Description

吸收性物品、不織布薄片及不織布薄片的製造方法Absorbent article, non-woven fabric sheet and manufacturing method of non-woven fabric sheet

本發明係關於吸收性物品、不織布薄片及不織布薄片的製造方法。The present invention relates to an absorbent article, a non-woven fabric sheet, and a manufacturing method of the non-woven fabric sheet.

以往以來，具備具有藉由顏料或染料構成的墨水之不織布薄片的吸收性物品為眾所皆知。例如，在專利文獻1，為了隱蔽排泄物，藉由墨水將不織布薄片著色成冷色系。 [先前技術文獻] [專利文獻] [專利文獻1]日本特開2008-93290號公報In the past, absorbent articles having non-woven fabric sheets with ink composed of pigments or dyes have been known. For example, in Patent Document 1, in order to conceal excrement, a non-woven fabric sheet is colored in a cool color with ink. [Prior Technical Literature] [Patent Literature] [Patent Document 1] JP 2008-93290 A

[發明所欲解決之問題] 在此，在將疏水性墨水配置於不織布薄片之罩體中，會有因疏水性墨水，造成構成不織布薄片的纖維間的間隙變窄，或該間隙被堵塞的情況。在此情況，由於配置有疏水性墨水的部分之通氣性惡化，故，在穿用具備該不織布薄片的吸收性物品的情況，會有容易產生悶熱之虞。 因此，本發明係為了解決前述課題，開發完成的發明，其目的係在於提供能夠抑制通氣性惡化之吸收性物品、不織布薄片及不織布薄片的製造方法。 一態樣之吸收性物品，係具備具有疏水性墨水的不織布薄片之吸收性物品，在前述不織布薄片的俯視視角，在前述不織布薄片，設有：配置有前述疏水性墨水之墨水區域、和未配置有前述疏水性墨水之非墨水區域，前述墨水區域的前述不織布薄片之厚度，係較前述非墨水區域的前述不織布薄片之厚度薄。 一態樣之不織布薄片係具有疏水性墨水且使用於吸收性物品之不織布薄片，其特徵為，在前述不織布薄片的俯視視角，在前述不織布薄片，設有配置有前述疏水性墨水之墨水區域、和未配置有前述疏水性墨水之非墨水區域，前述墨水區域的前述不織布薄片之厚度，係較前述非墨水區域的前述不織布薄片之厚度薄。 一態樣之不織布薄片的製造方法，係使用於吸收性物品之不織布薄片的製造方法，其特徵為具有：將藉由紫外線進行硬化的疏水性墨水配置於不織布之製程；及對至少配置有前述疏水性墨水的墨水區域，照射紫外線的製程。 在配置有疏水性墨水的墨水區域，藉由照射紫外線，可將從照射紫外線的裝置到不織布之間的空氣加溫。藉由已被加溫的空氣，可將不織布的纖維間之空氣加溫，因此，可使不織布的蓬鬆度增加。但，在墨水區域，因照射紫外線，使疏水性墨水會硬化而乾燥。藉此，以疏水性墨水使不織布的纖維彼此被接合，不織布的纖維彼此變得不易分離。藉此，即使墨水區域的不織布的纖維間的空氣被加溫，不織布薄片的蓬鬆度也不易增加。又，藉由照射於墨水區域之紫外線的能量，係因能量被用於疏水性墨水的硬化，故，墨水區域的不織布的纖維間的空氣不易加溫。其結果，能夠將墨水區域的不織布薄片之厚度作成較非墨水區域的不織布薄片之厚度薄。藉此，可製造能夠抑制吸收性物品的通氣性惡化之不織布薄片。[The problem to be solved by the invention] Here, when the hydrophobic ink is arranged in the cover of the non-woven fabric sheet, the gaps between the fibers constituting the non-woven fabric sheet may be narrowed or the gaps may be blocked due to the hydrophobic ink. In this case, since the air permeability of the portion where the hydrophobic ink is arranged is deteriorated, when the absorbent article provided with the non-woven fabric sheet is worn, there is a possibility that sultry may easily occur. Therefore, the present invention is an invention developed in order to solve the aforementioned problems, and its object is to provide an absorbent article, a non-woven fabric sheet, and a non-woven fabric sheet manufacturing method capable of suppressing deterioration in air permeability. One aspect of the absorbent article is an absorbent article provided with a non-woven fabric sheet with hydrophobic ink. In a plan view of the non-woven fabric sheet, the non-woven fabric sheet is provided with: an ink area where the hydrophobic ink is arranged, and a non-woven fabric sheet. The non-ink area where the hydrophobic ink is arranged, and the thickness of the non-woven fabric sheet in the ink area is thinner than the thickness of the non-woven fabric sheet in the non-ink area. One aspect of the non-woven fabric sheet is a non-woven fabric sheet that has hydrophobic ink and is used for absorbent articles. It is characterized in that, in a plan view of the non-woven fabric sheet, the non-woven fabric sheet is provided with an ink area where the hydrophobic ink is arranged, And the non-ink area where the hydrophobic ink is not arranged, the thickness of the non-woven fabric sheet in the ink area is thinner than the thickness of the non-woven fabric sheet in the non-ink area. One aspect of the method of manufacturing a non-woven fabric sheet is a method of manufacturing a non-woven fabric sheet used in absorbent articles, which is characterized by: disposing a hydrophobic ink hardened by ultraviolet rays on the non-woven fabric manufacturing process; and disposing at least the aforementioned The process of irradiating the ink area of the hydrophobic ink with ultraviolet rays. In the ink area where the hydrophobic ink is arranged, by irradiating ultraviolet rays, the air between the device that irradiates the ultraviolet rays and the non-woven fabric can be heated. With the heated air, the air between the fibers of the non-woven fabric can be heated, so that the bulkiness of the non-woven fabric can be increased. However, in the ink area, the hydrophobic ink hardens and dries due to ultraviolet radiation. Thereby, the fibers of the non-woven fabric are joined to each other with the hydrophobic ink, and the fibers of the non-woven fabric are not easily separated from each other. Thereby, even if the air between the fibers of the non-woven fabric in the ink area is heated, the bulkiness of the non-woven fabric sheet is not easily increased. In addition, the energy of the ultraviolet rays irradiated to the ink area is used to harden the hydrophobic ink. Therefore, the air between the fibers of the non-woven fabric in the ink area is not easily heated. As a result, the thickness of the non-woven fabric sheet in the ink area can be made thinner than the thickness of the non-woven fabric sheet in the non-ink area. Thereby, it is possible to manufacture a non-woven fabric sheet capable of suppressing the deterioration of the breathability of the absorbent article.

(1)實施形態之概要 依據本說明書及圖面的記載，至少可使以下的事項更明確。 一態樣之吸收性物品，係具備具有疏水性墨水的不織布薄片之吸收性物品，在前述不織布薄片的俯視視角，在前述不織布薄片，設有：配置有前述疏水性墨水之墨水區域、和未配置有前述疏水性墨水之非墨水區域，前述墨水區域的前述不織布薄片之厚度，係較前述非墨水區域的前述不織布薄片之厚度薄。 藉此，藉由厚度的差異，墨水區域的不織布薄片(以下稱為墨水部)係呈較非墨水區域的不織布薄片更凹陷的狀態，在不織布薄片形成凹部，亦即，形成空間。空氣係比起纖維糾纏的不織布薄片，更容易通過空間。因此，藉由以凹部使墨水部周邊的通氣性提升，能夠彌補因疏水性墨水造成容易降低的通氣性。其結果，能夠抑制吸收性物品的通氣性惡化。 若依據理想的一態樣，前述疏水性墨水係配置於厚度方向上之前述不織布薄片的一方側，在前述不織布薄片的一方側，設有比起前述墨水區域的周圍更朝前述厚度方向凹陷之凹部。由於在配置有疏水性墨水的一方側設置凹部，故，因疏水性墨水造成不易朝厚度方向通過的空氣能夠在凹部內朝平面方向通過。並且，凹部的側壁部分為墨水區域的周圍，故，凹部內的空氣容易透過側壁部分而通過墨水區域周圍之不織布薄片內。其結果，能夠抑制吸收性物品的通氣性惡化。 若依據理想的一態樣，前述非墨水區域的前述不織布薄片之纖維密度，係較前述墨水區域的前述不織布薄片的纖維密度小。藉此，由於非墨水區域的纖維間的間隙較大，故，在墨水區域的周圍之非墨水區域，空氣變得容易通過，使墨水區域周邊的通氣性提升，藉此，能夠彌補因疏水性墨水容易降低的通氣性。 若依據理想的一態樣，前述疏水性墨水係配置於前述厚度方向上之前述不織布薄片的一方側，前述不織布薄片的前述一方側之纖維的粗細度係較前述不織布薄片的另一方側之纖維的粗細度大。藉由使不織布薄片的一方側(亦即，配置有疏水性墨水之側)的纖維的粗細度增大，可增大該一方側的纖維間的間隙。藉此，在接近疏水性墨水的部分，可使空氣容易通過，能夠抑制通氣性惡化。 若依據理想的一態樣，前述疏水性墨水係配置於前述厚度方向上之前述不織布薄片的一方側，前述不織布薄片係具有從前述不織布薄片的另一方側朝前述厚度方向壓榨之壓榨部。在不織布薄片被壓榨的另一方側，因壓榨，造成纖維間的間隙變小。因此，藉由比起另一方側，在即使壓榨，纖維間的間隙也不易變小的不織布薄片的一方側，配置疏水性墨水，使得在接近疏水性墨水的部分，使空氣容易通過，能夠抑制通氣性惡化。 若依據理想的一態樣，具有與前述厚度方向上之前述不織布薄片的一方側抵接之抵接薄片，前述疏水性墨水係配置於前述不織布薄片的前述一方側。由於墨水區域的不織布薄片係較墨水區域的周圍之不織布薄片的厚度薄，故，在墨水區域，於不織布薄片與抵接薄片之間容易形成隙間(空間)。其結果，在墨水區域，變得容易通過不織布薄片與抵接薄片之間的間隙，能夠抑制吸收性物品的通氣性惡化。又，由於疏水性墨水配置於與抵接薄片抵接的不織布薄片的一方側，故，疏水性墨水不直接接觸於穿用者的肌膚，能夠抑制疏水性墨水附著於穿用者的肌膚。 若依據理想的一態樣，還具有複合薄片，其具有與前述厚度方向之前述不織布薄片的一方側抵接之抵接薄片、和前述不織布薄片，前述複合薄片，係具有前述不織布薄片與前述抵接薄片收縮之收縮區域，前述墨水區域的至少一部，係與前述收縮區域在前述厚度方向上重疊，在前述墨水區域的至少一部分，前述不織布薄片與前述抵接薄片係為非接合。藉此，由於在墨水區域的至少一部分，不織布薄片與抵接薄片未接合，故，不織布薄片與抵接薄片可朝厚度方向分離。在墨水區域的至少一部分，在藉由收縮區域的收縮而形成皺紋的情況，不織布薄片與抵接薄片變得容易分離，可擴大不織布薄片與抵接薄片之間的空間。其結果，空氣變得更容易通過不織布薄片與抵接薄片之間的間隙，能夠抑制吸收性物品的通氣性惡化。又，由於比起非墨水區域，墨水區域的剛性較高，故，在墨水區域，比較不容易形成皺紋，容易維持不織布薄片與抵接薄片抵接的狀態。即使為不織布薄片與抵接薄片抵接的狀態，藉由形成於不織布薄片的凹部，亦可彌補通氣性。 若依據理想的一態樣，前述不織布薄片，係具有將前述不織布薄片翻折之翻折部；及與前述翻折部相對向且與前述翻折部抵接之對向部，前述翻折部的前述疏水性墨水的至少一部分，係配置於前述對向部之與前述疏水性墨水在前述厚度方向上重疊的位置。藉此，翻折部的疏水性墨水的至少一部分，係在與對向部的疏水性墨水在厚度方向上重疊的區域，變得容易形成更大的空間。其結果，空氣變得更容易通過翻折部與對向部之間的間隙，能夠抑制吸收性物品的通氣性惡化。 若依據理想的一態樣，前述吸收性物品係具有吸收體，該吸收體是配置於較前述不織布薄片更靠近非肌膚面側，且與前述墨水區域及非墨水區域在厚度方向重疊，前述疏水性墨水係配置於前述不織布薄片的非肌膚面側，前述非墨水區域的前述不織布薄片的纖維密度係較前述墨水區域的前述不織布的纖維密度小。由於疏水性墨水配置於非肌膚面側，故，疏水性墨水不直接接觸於穿用者的肌膚，能夠抑制疏水性墨水附著於穿用者的肌膚。在非墨水區域，由於不織布薄片的厚度較厚，故，排泄物容易接觸到非墨水區域的不織布薄片，能夠加速開始進行排泄物的吸入。並且，由於墨水區域的纖維密度較大、且疏水性墨水配置於不織布薄片的非肌膚面側，故，能以不織布薄片的肌膚面側之表面全體，吸入排泄物。因此，能夠防止吸收速度降低。又，在墨水區域，即使因疏水性墨水，造成排泄物不易朝不織布薄片的非肌膚面側通過，排泄物也可經由非墨水區域而朝不織布薄片的非肌膚面側移動，因此，能夠抑制吸收性能降低。 若依據理想的一態樣，前述吸收性物品係具有吸收體，該吸收體是配置於較前述不織布薄片更靠近非肌膚面側，且與前述墨水區域及非墨水區域在厚度方向上重疊，前述疏水性墨水係配置於前述不織布薄片的肌膚面側，前述非墨水區域的前述不織布薄片的纖維密度，係較前述墨水區域的前述不織布薄片的纖維密度小。在非墨水區域，由於不織布薄片的厚度較厚，故，排泄物容易接觸到非墨水區域的不織布薄片，能夠加速開始進行排泄物的吸入。又，將在非墨水區域開始吸入的排泄物，能夠在纖維密度高的墨水區域的非肌膚面側之部分，藉由毛細管現象加以吸入，能夠抑制將排泄物吸入的速度降低。由於疏水性墨水係配置於不織布薄片的肌膚面側，故，在墨水區域，排泄物不易從不織布薄片朝肌膚面側回流，能夠減輕再回濕(re-wetting back)。 若依據理想的一態樣，還具有：配置於較前述不織布薄片更靠近非肌膚面側，且與前述墨水區域及非墨水區域在厚度方向上重疊的吸收體；及具有抵接於前述穿用者的肌膚的抵接面之肌膚面薄片，前述不織布薄片係在前述厚度方向上，配置於前述肌膚面薄片與前述吸收體之間。由於能夠以肌膚面薄片迅速地吸收排泄物，故，排泄物不會持續殘留於肌膚面薄片的抵接面，因此，能夠抑制排泄物沿著穿用者的身體漏出。又，由於在較具有疏水性墨水的不織布薄片更靠近肌膚面側，存在有肌膚面薄片，故，能夠抑制疏水性墨水附著於穿用者的肌膚。 若依據理想的一態樣，以前述墨水區域與前述非墨水區域的邊界作為境界，前述墨水區域的前述前述不織布薄片的厚度係較前述非墨水區域的前述不織布薄片的纖維密度薄。藉由在墨水區域與非墨水區域的邊界附近，改變不織布薄片的厚度，從不用配置疏水性墨水處，能夠設置凹部的側壁部分。藉此，能使墨水部周邊的通氣性提升，因此，能夠彌補因疏水性墨水造成容易降低的通氣性。其結果，能夠抑制吸收性物品的通氣性惡化。 一態樣之不織布薄片係具有疏水性墨水且使用於吸收性物品之不織布薄片，其特徵為，在前述不織布薄片的俯視視角，在前述不織布薄片，設有配置有前述疏水性墨水之墨水區域、和未配置有前述疏水性墨水之非墨水區域，前述墨水區域的前述不織布薄片之厚度，係較前述非墨水區域的前述不織布薄片之厚度薄。 一態樣之不織布薄片的製造方法，係使用於吸收性物品之不織布薄片的製造方法，其特徵為具有：將藉由紫外線進行硬化的疏水性墨水配置於不織布之製程；及對至少配置有前述疏水性墨水的墨水區域，照射紫外線的製程。在配置有疏水性墨水的墨水區域，藉由照射紫外線，可將從照射紫外線的裝置到不織布之間的空氣加溫。藉由已被加溫的空氣，可將不織布的纖維間之空氣加溫，因此，可使不織布的蓬鬆度增加。但，在墨水區域，因照射紫外線，使疏水性墨水會硬化而乾燥。藉此，以疏水性墨水使不織布的纖維彼此被接合，不織布的纖維彼此變得不易分離。藉此，即使墨水區域的不織布的纖維間的空氣被加溫，不織布薄片的蓬鬆度也不易增加。又，藉由照射於墨水區域之紫外線的能量，係因能量被用於疏水性墨水的硬化，故，墨水區域的不織布的纖維間的空氣不易加溫。其結果，能夠將墨水區域的不織布薄片之厚度作成較非墨水區域的不織布薄片之厚度薄。藉此，可製造能夠抑制吸收性物品的通氣性惡化之不織布薄片。

外裝體15係具備腰圍彈性構件WE，其具有伸縮性。腰圍彈性構件WE係配置成朝寬度方向W延伸，在寬度方向W上具有伸縮性。腰圍彈性構件WE係在前後方向L上配置有複數個。腰圍彈性構件WE係具有：配置於前外裝體20之前腰圍彈性構件22；及配置於後外裝體30之後腰圍彈性構件32。前腰圍彈性構件22係在厚度方向T上，配置於第1前側薄片25與第2前側薄片26之間。後腰圍彈性構件32係在厚度方向T上，配置於第1後側薄片35與第2後側薄片36之間。腰圍彈性構件WE係例如藉由可朝寬度方向W伸縮之橡膠線、或可朝寬度方向W伸縮之彈性薄片構成。腰圍彈性構件WE亦可例如藉由以可伸縮的薄片形成的外裝體15本身來構成。本實施形態的腰圍彈性構件WE係藉由橡膠線構成。 吸收性本體40係至少配置於胯下區域S3。吸收性本體40亦可配置遍及於前側區域S1、後側區域S2及胯下區域S3。吸收性本體40係前外裝體20及後外裝體30作為不同體構成，在前側區域S1及後側區域S2，分別與前外裝體20及後外裝體30接合。 吸收性本體40(吸收性物品1)係具有吸收體50。吸收體50係至少具有吸收芯材。吸收芯材係包含吸收液體的吸收材料。吸收芯材係包含例如粉碎紙漿或高吸收性聚合物(SAP)、或該等的混合物。吸收芯材係至少配置於胯下區域S3。吸收芯材可配置於前側區域S1，亦可配置於後側區域S2。吸收芯材係在前後方向L上，從前側區域S1延伸至後側區域S2的範圍。吸收體50亦可具有用來覆蓋吸收芯材之芯材繞包層。芯材繞包層係在厚度方向T上夾著吸收芯材。芯材繞包層係藉由例如薄紙、不織布等構成。 吸收性本體40係具有：位於吸收體50的肌膚面側T1之肌膚面薄片41；位於吸收體50的非肌膚面側T2之不透液性薄片42；及配置於較不透液性薄片42更靠近非肌膚面側T2之本體薄片43。肌膚面薄片41係具有抵接於穿用者的肌膚之抵接面。肌膚面薄片41係具有：覆蓋吸收體50的寬度方向W的中央之中央薄片41A；和在較中央薄片41A更靠近肌膚面側T1，覆蓋中央薄片41A的外側部之一對側薄片41B。肌膚面薄片41係具有透液性即可，例如可藉由不織布構成。不透液性薄片42係具有不透液性即可，例如可藉由薄膜構成。本體薄片43係具有疏水性即可，例如可藉由具有疏水性的不織布構成。 (3)不織布薄片 其次，使用圖2至圖5，說明關於不織布薄片10。吸收性物品1係具備以不織布構成的不織布薄片10。不織布係為例如熱風不織布、紡黏不織布、水針不織布等之任一者。不織布薄片10係第1前側薄片25、第2前側薄片26、第1後側薄片35、第2後側薄片36、中央薄片41A、側薄片41B、本體薄片43中的至少其中一者。 不織布薄片10具有疏水性墨水2。在不織布薄片10的俯視視角，在不織布薄片10，設有：配置有疏水性墨水2的墨水區域IR；及未配置有疏水性墨水2的非墨水區域NR。疏水性墨水2係例如藉由印刷進行配置(塗佈)。印刷疏水性墨水2的方法，可為柔版印刷，亦可為凹版印刷。疏水性墨水2係包含藉由紫外線(UV)硬化的材料。作為藉由紫外線硬化的材料，例如可舉出聚氨酯丙烯酸酯，丙烯酸樹脂丙烯酸酯，環氧丙烯酸酯。疏水性墨水2是否含有藉由紫外線硬化的材料，可藉由以下的方法進行測定。 第1，使用鑷子，從墨水區域IR的不織布薄片10(墨水部11)，採取疏水性墨水2。第2，使用傅立葉變換紅外線分光光度計(FT-IR)，對採取到的疏水性墨水2照射紅外線，測定官能基的峰值。第3，判定測定到的峰值與藉由紫外線硬化的習知材料之峰值是否一致。在測定到的峰值一致的情況，能夠判定疏水性墨水藉由紫外線硬化。 如圖2所示，墨水區域IR係具有：第1墨水區域IR1、第2墨水區域IR2、第3墨水區域IR3、及第4墨水區域IR4。第1墨水區域IR1係設在構成中央薄片41A之不織布薄片10。第2墨水區域IR2及第3墨水區域IR係在構成側薄片41B之不織布薄片10。第2墨水區域IR2係設在配置有立體皺褶之部分。第3墨水區域IR3係設在配置有腳皺褶之部分。第4墨水區域IR4係設在第2前側薄片26及第2後側薄片36。 再者，立體皺褶係可朝肌膚面側T1立起。立體皺褶係具有：藉由朝前後方向L具有伸縮性的第1彈性構件65之收縮，可立起的立起部；及將側薄片41B與配置於較側薄片41B更靠近非肌膚面側T2的構成構件接合之接合部。立體皺褶係藉由立起而形成為牆壁，可防止排泄物朝寬度方向W的外側移動。又，腳皺褶係配置於較立體皺褶更靠近寬度方向W的外側，且藉由朝前後方向L具有伸縮性的第2彈性構件66之收縮進行收縮。腳皺褶係與穿用者的腳圍吻合，防止排泄物從吸收性物品洩漏。 不織布薄片10係具有：藉由墨水區域IR的不織布薄片10構成的墨水部11；及藉由非墨水區域NR的不織布薄片10構成的非墨水部12。墨水部11係具有：疏水性墨水2存在的墨水層11A；及疏水性墨水2不存在的非墨水層11B。墨水層11A係在不織布薄片10疏水性墨水滲入的部分及該疏水性墨水2構成。 在本說明書中，[疏水性]係指不易與水混合或不易保持水分之性質，例如與離子交換水之接觸角度為80°以上者。再者，與離子交換水之接觸角度係可藉由日本特開2005-324010號公報之[初期接觸角度的測定]所記載的方法進行測定。 疏水性墨水2係配置於厚度方向T上之不織布薄片10的一方側。因此，疏水性墨水2，亦即，墨水層11A係可配置於厚度方向T上之不織布薄片10的非肌膚面側T2，亦可配置於厚度方向T上之不織布薄片10的肌膚面側T1。如圖4B、圖4C及圖5所示，在不織布薄片10的一方側，設有較墨水區域IR的周圍更朝厚度方向T凹陷的凹部S。亦即，設有從配置有疏水性墨水2之側朝厚度方向T凹陷的凹部S。圖4B及圖4C中，凹部S係從非肌膚面側T2朝肌膚面側T1凹陷。圖5A中，凹部S係從肌膚面側T1朝非肌膚面側T2凹陷。在圖5B，凹部S係在肌膚面側T1的不織布薄片10，從非肌膚面側T2朝肌膚面側T1凹陷，在非肌膚面側T2的不織布薄片10，從肌膚面側T1朝非肌膚面側T2凹陷。 如圖4B所示，墨水區域IR的不織布薄片10(亦即，墨水部11)之厚度Ti係較非墨水區域NR的不織布薄片10(亦即，非墨水部12)之厚度Tn薄。例如，非墨水部12的厚度Tn對墨水部11的厚度Ti之比(Tn/Ti)為0.85以下。在此情況，由於能夠增大藉由凹部S所形成的空間，故，可使吸收性物品的通氣性提升。又，厚度的比(Tn/Ti)亦可為0.2以上。在此情況，穿用者不易感到墨水區域IR與非墨水區域NR之邊界的階差。因此，不易對穿用者施加不舒服感，能夠抑制吸收性物品1的穿著舒適度惡化。例如在墨水部11的厚度Ti為1.1~1.3μm的情況，非墨水部12的厚度Tn係1.6~1.8μm。再者，墨水部11的所有厚度亦可不會比非墨水部12的所有的厚度大。 在不織布薄片10的俯視視角，以墨水區域IR與非墨水區域NR之邊界(以下稱為墨水邊界)作為境界，墨水區域IR的不織布薄片10的厚度Ti，係較非墨水區域NR的不織布薄片10的厚度Tn薄。凹部S的側壁部分係存在有未被疏水性墨水2覆蓋的部分。凹部S的側壁部分係非全部被疏水性墨水2覆蓋為佳。凹部S的底部係藉由墨水層11A構成，未以非墨水層11B構成。亦即，僅墨水層11A構成凹部S的底部。 再者，在圖3及圖4A中，請注意是以容易了解的方式顯示疏水性墨水2(墨水層11A)的配置場所，並非顯示疏水性墨水2的厚度更不是顯示不織布薄片10的厚度。 不織布薄片10的厚度係例如能藉由以下的方法進行測定。使用數位顯微鏡(例如基恩斯(KEYENCE CORPORATION)公司製的數位顯微鏡VHX-100)，從對不織布薄片10的切斷面垂直的方向進行放大圖像進行攝像。放大圖像為擴大成可對不織布薄片10的厚度方向T全體進行攝像的倍率的圖像，放大倍率為例如20至50倍。依據獲得的放大圖像，測定不織布薄片10的厚度。放大圖像係亦可為了容易測定厚度而進行圖像處理。分別在與非墨水區域NR之平滑的部分(亦即，未受到壓榨及印刷等的影響之部分)、和墨水區域IR，將在各別的3個部位之切斷面測定到的厚度之平均值作為不織布薄片10的厚度。 非墨水區域NR的不織布薄片10之纖維密度，係較墨水區域IR的不織布薄片10之纖維密度小。因此，墨水部11的非墨水層11B之纖維密度，係較非墨水部12的纖維密度小。不織布薄片10的纖維密度係例如能藉由以下的方法進行測定。具體而言，在測定墨水區域IR與非墨水區域NR之各自的不織布薄片10的纖維密度的情況，能採用以下的方法。 第1，將墨水部11與非墨水部12裁切成10mm×10mm的大小而作為試料。第2，使用掃描型電子顯微鏡(日本電子(股)公司製：JCM-5100)，將試料之與厚度方向T平行的切斷面放大觀察。倍率為能在一畫面內測量30~60條的纖維之斷面的倍率(例如：150~500倍)。第3，分別在墨水部11與非墨水部12，測量纖維的斷面之數量。具體而言，在預定面積的切斷面，計算被切斷的纖維的斷面之數量。在墨水部11，纖維為了迴避因吸收疏水性墨水2之影響，在厚度方向T上分成墨水層11A與非墨水層11B，並且測量非墨水層11B上之纖維的斷面之數量。不織布薄片10係藉由層積複數個纖維層所構成的情況，在墨水部11與非墨水部12，於相同的纖維層，計算被切斷的纖維的斷面之數量。第4，將獲得的纖維的斷面之數量換算成1mm2 左右的纖維的斷面之數量，將此作為纖維密度(條/mm2 )。測定是在3個部位進行，將測定值之平均值作為該試料的纖維密度。 再者，作為纖維密度，使用與厚度方向T平行的斷面之每單位面積的纖維的條數，但作為纖維密度，亦可使用每單位體積之纖維的條數。每單位體積之纖維的條數係例如可藉由X射線CT之解析來求取。在每單位面積的纖維密度、和每單位體積的纖維密度，數值雖不同，但，在纖維密度的相對的比較(例如，大小的比較)，則成為相同。 又，配置有疏水性墨水2的一方側的不織布薄片10的纖維密度，係較未配置有疏水性墨水2的另一方側的不織布薄片10之面的纖維密度小。藉此，可增大配置有疏水性墨水2之側的纖維間的間隙，在配置有疏水性墨水2之側，容易使空氣通過，能夠抑制通氣性惡化。再者，在此情況之纖維密度係能藉由以下的方法進行測定。 分別對於配置有疏水性墨水2的一方側的不織布薄片10之面(例如圖4的肌膚面薄片41之非肌膚面側T2的面)、和未配置有疏水性墨水2的另一方側的不織布薄片10之面(例如圖4的肌膚面薄片41之肌膚面側T1的面)，使用電子顯微鏡或顯微鏡(例如基恩斯(KEYENCE CORPORATION)公司製的VHX-2000等)進行攝像，獲得纖維的放大圖像。測定圖像中的每單位面積之纖維的面積。藉此，算出纖維的面積率。將纖維的面積率視為纖維密度，能夠比較一方側的不織布薄片10的纖維密度與另一方側的不織布薄片10的纖維密度。 又，配置有疏水性墨水2的一方側的不織布薄片10的纖維之粗細度，係較未配置有疏水性墨水2的另一方側的不織布薄片10的纖維之粗細度粗。因此，墨水層11A或接近墨水層11A的非墨水層11B之纖維的粗細度係較距離墨水層11A遠的非墨水層11B之纖維的粗細度粗。纖維的粗細度係例如能藉由以下的方法進行測定。 藉由電子顯微鏡或顯微鏡(例如基恩斯(KEYENCE CORPORATION)公司製的VHX-2000等)，獲得纖維的放大圖像，藉由測定相當於呈現在圖像中的纖維的直徑之2點間的距離來進行。分別在配置有疏水性墨水2的一方側的不織布薄片10之面(例如圖4的肌膚面薄片41之非肌膚面側T2的面)、和未配置有疏水性墨水2的另一方側之不織布薄片10的面(例如圖4的肌膚面薄片41之肌膚面側T1的面)，進行複數次(次數為以100為基準)之測定。將測定到的纖維之直徑的平均值作為纖維的粗細度。因此，纖維之直徑的平均值較大者，判定為纖維的粗細度為大。 又，在疏水性墨水2配置於肌膚面側T1的情況，在非墨水部12，肌膚面側T1的纖維的粗細度係較非肌膚面側T2的纖維的粗細度大。又，不織布薄片10係具有朝厚度方向T被壓榨的壓榨部(未圖示)。在墨水區域IR，亦可不設置壓榨部。因此，在不織布薄片10，僅在非墨水區域NR設置壓榨部。在墨水區域IR，亦可設置壓榨部。不織布薄片10具有從未配置有疏水性墨水2之另一方側進行壓榨之壓榨部。再者，不織布薄片10亦可具有從配置有疏水性墨水2之側進行壓榨之壓榨部。 又，吸收性物品1係具有複合薄片13。複合薄片13係包含：配置有疏水性墨水2之不織布薄片10；及與厚度方向T上之不織布薄片10的一方側抵接之抵接薄片。例如，如圖5A所示，在複合薄片13是藉由將第1薄片13A及第2薄片13B朝厚度方向T層積而構成的情況，第1薄片13A係為配置有疏水性墨水2之不織布薄片10，第2薄片13B係為與厚度方向T上之不織布薄片10的一方側抵接之抵接薄片。第1薄片13A與第2薄片13B是藉由接合部B接合。 如圖5A所示，複合薄片13係具有第1薄片13A(不織布薄片10)與第2薄片13B(抵接薄片)收縮之收縮區域CR。在收縮區域CR，亦可藉由複合薄片13所含有的彈性構件(例如腰圍彈性構件WE、第1彈性構件65、第2彈性構件66等)，使第1薄片13A及第2薄片13B收縮，亦可藉由第1薄片13A及第2薄片13B中的至少一方為薄片狀的彈性構件，使第1薄片13A及第2薄片13B收縮。 如圖5A所示，墨水區域IR的至少一部分係與收縮區域CR在厚度方向T上重疊。墨水區域IR的至少一部分係第1薄片13A與第2薄片13B為非接合。因此，將薄片彼此接合的接合部B係在厚度方向T上不與墨水區域IR重疊。亦可為墨水區域IR的所有範圍為非接合。 如圖4A所示，不織布薄片10係具有：不織布薄片10被翻折之翻折部10f；及與翻折部10f相對向，且與翻折部10f抵接之對向部10c。對向部10c係為不織布薄片10未被翻折的部分。如圖5B所示，翻折部10f中的疏水性墨水2之至少一部分，係配置於與對向部10c的疏水性墨水2在厚度方向T上重疊的位置。 又，如圖4所示，吸收體50係配置於較不織布薄片10更靠近非肌膚面側T2。吸收體50係與墨水區域IR及非墨水區域NR在厚度方向T上重疊。疏水性墨水2係配置於不織布薄片10的非肌膚面側T2。因此，墨水層11A係配置於不織布薄片10的非肌膚面側T2。如前述般，非墨水區域NR的不織布薄片10之纖維密度，係較墨水區域IR的不織布薄片10之纖維密度小。 又，墨水區域IR與非墨水區域NR之墨水邊界附近的非墨水區域NR(例如從墨水邊界起之5mm的範圍內)之不織布薄片10的纖維密度、和從墨水邊界起分離預定距離之非墨水區域NR(例如從墨水邊界起之10mm~15mm的範圍)之不織布薄片10的纖維密度之差為5%以內。藉此，由於在從墨水邊界的附近起之預定的範圍，非墨水區域NR的不織布薄片10的纖維密度不會大幅地改變，故，在非墨水區域NR，能使通氣性及吸收性能穩定。 又，墨水邊界近傍的墨水區域IR(例如墨水邊界起之5mm的範圍內)之不織布薄片10的纖維密度、與從墨水邊界起分離預定距離之墨水區域IR(例如從墨水邊界起之10mm~15mm的範圍)之不織布薄片10的纖維密度之差為5%以內。藉此，由於在從墨水邊界的附近起之預定的範圍，墨水區域IR的不織布薄片10的纖維密度不會大幅地改變，故，在墨水區域IR，能抑制通氣性及吸收性能大幅惡化。 如以上所述，在吸收性物品1，藉由墨水部11與非墨水部12之厚度的差異，墨水區域IR的不織布薄片10係為較非墨水區域NR的不織布薄片10更凹陷的狀態。藉由此厚度的差異，在不織布薄片10形成凹部S亦即空間。在此，在墨水層11A，因疏水性墨水2，會造成纖維間的間隙變小，或堵塞。因此，如圖4B所示，從墨水部11朝凹部S通過之空氣的量會減少。另外，由於比起纖維糾纏的不織布薄片10，空氣更容易通過空間，故，因疏水性墨水2造成不易朝厚度方向通過之空氣能夠在凹部S內朝平面方向P通過。並且，凹部S的側壁部分為墨水區域IR的周圍，故，凹部S內的空氣容易透過側壁部分而通過非墨水部12之不織布薄片10內。其結果，凹部S內的空氣可透過非墨水部12而變得容易與外部交換。因此，藉由以凹部S使墨水部11周邊的通氣性提升，能夠彌補因疏水性墨水2造成容易降低的通氣性。其結果，能夠抑制吸收性物品1的通氣性惡化。 又，非墨水區域NR的不織布薄片10之纖維密度，係較墨水區域IR的不織布薄片10之纖維密度小的情況，非墨水區域NR的纖維間的間隙變大。 藉此，在墨水區域IR的周圍之非墨水區域NR，空氣變得容易通過，使墨水部11周邊的通氣性提升，藉此，能夠彌補因疏水性墨水2容易降低的通氣性。 又，配置有疏水性墨水2的一方側(墨水層11A側)的不織布薄片10的纖維之粗細度，係較未配置有疏水性墨水2的另一方側(非墨水層11B側)的不織布薄片10的纖維之粗細度粗的情況，能夠使一方側的纖維間之間隙變大。藉此，在接近疏水性墨水2的部分，可使空氣容易通過，能夠抑制通氣性惡化。 又，在不織布薄片10具有從未配置有疏水性墨水2之另一方側(非墨水層11B側)進行壓榨之壓榨部的情況，在另一方側，因進行壓榨，使纖維間的間隙變小。因此，藉由比起另一方側，在即使進行壓榨，纖維間的間隙也不易變小的不織布薄片10的一方側，配置疏水性墨水2，使得在接近疏水性墨水2的部分，使空氣容易通過，能夠抑制通氣性惡化。 又，以墨水邊界為境界，墨水區域IR的不織布薄片10之厚度Ti係較非墨水區域NR的不織布薄片10之厚度Tn薄，故，在墨水邊界附近，可改變不織布薄片10的厚度。藉此，能從不配置疏水性墨水2處設置凹部S的側壁部分，故，能夠彌補因疏水性墨水2造成容易降低的通氣性。其結果，能夠抑制吸收性物品的通氣性惡化。 又，如圖5A所示，疏水性墨水2係配置於配置有作為抵接薄片之第2薄片13B之側的情況，藉由凹部S，可在第1薄片13A與第2薄片13B之間容易形成間隙(空間)。其結果，在墨水區域IR，變得容易通過第1薄片13A與第2薄片13B之間的空間，能夠抑制吸收性物品1的通氣性惡化。並且，由於疏水性墨水2未露出，故，疏水性墨水2不直接接觸於穿用者的肌膚，能夠抑制疏水性墨水2附著於穿用者的肌膚。 又，如圖5A所示，墨水區域IR的至少一部分係第1薄片13A與第2薄片13B為非接合。藉此，由於在墨水區域IR的至少一部分，第1薄片13A與第2薄片13B未接合，故，第1薄片13A與第2薄片13B可朝厚度方向T分離。在墨水區域IR的至少一部分，在藉由收縮區域CR的收縮而形成皺紋的情況，第1薄片13A與第2薄片13B變得容易分離，可擴大第1薄片13A與第2薄片13B之間的空間。其結果，空氣變得更容易通過第1薄片13A與第2薄片13B之間的間隙，能夠抑制吸收性物品的通氣性惡化。並且，由於比起非墨水區域NR，墨水區域IR的剛性較高，故，在墨水區域IR，比較不容易形成皺紋，容易維持第1薄片13A與第2薄片13B抵接的狀態。即使為第1薄片13A與第2薄片13B抵接的狀態，藉由形成於第1薄片13A的凹部S，亦可彌補通氣性。 又，如圖5B所示，翻折部10f中的疏水性墨水2之至少一部分，係配置於與對向部10c的疏水性墨水2在厚度方向T上重疊的位置，因此，在墨水部11彼此重疊的區域，變得容易形成更大的空間。其結果，空氣變得更容易通過翻折部10f與對向部10c之間的間隙，能夠抑制吸收性物品1的通氣性惡化。 並且，如圖4C所示，在疏水性墨水2配置於不織布薄片10的非肌膚面側T2的情況，能以不織布薄片10的肌膚面側T1之表面全體，吸入排泄物。並且，在墨水區域IR，即使因墨水層11A(疏水性墨水2)，造成排泄物E不易朝不織布薄片10的非肌膚面側T2通過，排泄物E也可經由非墨水部12而朝不織布薄片的非肌膚面側T2移動，因此，能夠抑制吸收性能降低。尤其是在墨水部11的纖維密度較非墨水部12的纖維密度小的情況，可藉由非毛細管現象，將被吸入於非墨水層11B的排泄物E吸入到非墨水部12，故，能夠防止吸收速度降低。 且，由於可透過凹部S，在吸收體50的表面上擴散，故，能夠防止吸收速度降低。又，被吸收體50吸收的排泄物E係藉由墨水層11A變得不易返回肌膚面側T1，故，能夠減低再回濕。 (4)第2實施形態 其次，使用圖6至圖8說明關於第2實施形態。圖6係自肌膚面側觀看吸收性物品1的示意平面圖。圖7及圖8係圖6中之F7-F斷面之吸收性物品1的示意斷面圖。圖8係說明各構件的配置關係的圖，各構件簡單化顯示。 作為第2實施形態的吸收性物品，以生理用衛生棉為例，說明實施形態。吸收性物品1係不限於生理用衛生棉，亦可為衛生護墊、或輕失禁用墊片等。吸收性物品1係固定於使用者的穿著用物品來使用。再者，針對與第1實施形態相同的部分，省略其說明。 吸收性物品1係具有一對翼片1W。一對翼片1W係較寬度方向W之吸收體50(吸收芯材)的外側緣更朝寬度方向的外側延伸伸出。因此，從前後方向L的中央部朝寬度方向W的兩外側延伸伸出。又，一對翼片1W係當使用吸收性物品1時可進行翻折。 吸收性物品1具有：肌膚面薄片41、第二薄片45、吸收體50、不透液性薄片42、及背後側薄片47。如圖3所示，在厚度方向T上，層積有肌膚面薄片41、第二薄片45、吸收體50、背後側薄片47、及不透液性薄片42。肌膚面薄片41、第二薄片45、吸收體50、不透液性薄片42、及背後側薄片47係藉由接合部接合固定。作為接合部，例如可使用熱熔膠接著劑等的接著劑HMA。第二薄片45係配置於肌膚面薄片41與吸收體50之間。第二薄片45為不織布薄片，可舉出例如熱風不織布、紡黏不織布、水針不織布等。 在本實施形態，肌膚面薄片41與第二薄片45係藉由接著劑HMA接著成一體的狀態下，將吸收體50以包住寬度方向W的端部的方式捲入。肌膚面薄片41係在吸收體50的非肌膚面側，在接合部84以接著劑HMA接合固定。構成肌膚面薄片41、第二薄片45及吸收體50成為一體之本體部80。 再者，在將各構件彼此接合固定的接著劑HMA，不需要在全區域塗佈接著劑。特別是藉由調整作為肌膚面薄片41與第二薄片45之間的接著劑HMA進行塗佈的接著劑的量、區域、塗佈圖案等，能夠確保本體部80中之較後述的一對本體接合部85更靠近寬度方向W的外側之柔軟性，能夠使肌膚觸感提升。 本體接合部85係將本體部80與非肌膚側薄片接合。在本實施形態，在本體接合部85，使用熱熔膠等的接著劑，將本體部80的非肌膚面側之面、和背後側薄片47的肌膚面側之面接合。如圖1所示，本體接合部85為沿著前後方向L之連續形狀。本體接合部85係配置於寬度方向W的兩側之端部。非肌膚側薄片，可僅為不透液性薄片42，亦可為將不透液性薄片42與背後側薄片47結合者。 肌膚面薄片41係具有寬度方向W的兩側之側端部朝非肌膚面側T2翻折之一對第1翻折部2h。一對第1翻折部2h係藉由本體接合部85，與背後側薄片47接合。一對第1翻折部2h的寬度方向之前端，係位於較本體接合部85的外側緣更靠近寬度方向W的內側。藉此，肌膚面薄片41(第1翻折部2h)的前端(邊緣)不會露出。因此，由於肌膚面薄片41的前端不會與穿用者的肌膚碰觸，故，可抑制肌膚觸感惡化。第二薄片45係具有寬度方向W的兩側之側端部朝非肌膚面側T2翻折之一對第2翻折部3h。背後側薄片47為疏水性的薄片構件，可舉出例如熱風不織布、紡黏不織布、水針不織布等。 在吸收性物品1的非肌膚側面(亦即，不透液性薄片42的非肌膚側面)，設有塗佈有接著劑等之中央黏著部8。藉由中央黏著部8在吸收性物品1使用時黏貼於貼身衣物等的穿著用物品之肌膚側面，將吸收性物品1固定於貼身衣物等。同樣地，在各翼片1W的厚度方向T之非肌膚側面(不透液性薄片42的非肌膚面側T2)，設有翼片黏著部9。 吸收體50係吸收排泄物而將其保持於內部之構件。在本實施形態，如圖3、圖4、圖6所示，吸收體50具有：第1吸收芯材51A、第2吸收芯材51B、及覆蓋薄片52。第1吸收芯材51A係為與第1實施形態的吸收芯材相同的結構。第2吸收芯材51B係為將吸液性粒狀物亦即高吸收性聚合物(所謂SAP)等從肌膚側面及非肌膚側面分別以薄紙等的透液性薄片夾持之薄片狀構件。覆蓋薄片52為透液性的薄片構件，可舉出例如熱風不織布、紡黏不織布、水針不織布等。 覆蓋薄片52係夾於第1吸收芯材51A與第2吸收芯材51B之間。 如圖8所示，第二薄片45具有疏水性墨水2。藉此，由於能夠以肌膚面薄片41迅速地吸收排泄物，故，排泄物不會持續殘留於肌膚面薄片41的抵接面。因此，能夠抑制排泄物沿著穿用者的身體漏出。又，由於在較具有疏水性墨水2的第二薄片45更靠近肌膚面側T1，存在有肌膚面薄片41，故，能夠抑制疏水性墨水2附著於穿用者的肌膚。 如圖6所示，亦可藉由疏水性墨水2，對吸收性物品1施加設計。疏水性墨水2配置於第二薄片45的肌膚面側T1。藉此，比起在第二薄片45的非肌膚面側T2配置疏水性墨水2的情況，可更容易辨識設計。 (5)變更例 其次，使用圖9，說明關於變更例。圖9係變形例之吸收性物品的示意斷面圖。圖9係與圖4B及圖4C同樣地，中央薄片41A及吸收體50的放大示意斷面圖。再者，在以下的說明，對於與前述作過說明的內容相同的說明予以省略。 如圖9所示，疏水性墨水2係配置於不織布薄片10的肌膚面側T1。在非墨水區域NR，由於不織布薄片10的厚度較厚，故，排泄物E容易接觸到非墨水區域NR的不織布薄片10，能夠加速開始進行排泄物E的吸入。又，排泄到墨水區域IR的排泄物E，容易與凹部S的側壁亦即非墨水部12接觸，可經由非墨水部12到達吸收體50。 在非墨水部12的纖維密度較墨水部11(非墨水層11B)的纖維密度小的情況，將在非墨水區域NR開始吸入的排泄物E，能夠在纖維密度高的墨水部11的，藉由毛細管現象加以吸入，因此，能夠抑制將排泄物E吸入的速度降低。且，由於疏水性墨水2係配置於不織布薄片10的肌膚面側T1，故，在墨水區域IR，排泄物不易從不織布薄片朝肌膚面側回流，能夠減輕再回濕(re-wetting back)。又，在不織布薄片10係具有抵接於穿用者的肌膚的抵接面的情況，由於疏水性墨水2配置於凹部S的底面，故，疏水性墨水不易附著於穿用者的肌膚。 (6)不織布薄片的製造方法 其次，使用圖10，說明關於不織布薄片10的製造方法。圖10係用來說明不織布薄片10的製造方法的圖。將製造過程之搬運構成零件方向作為搬運方向MD加以顯示。如圖10所示，將不織布10C朝搬運方向MD搬運。不織布10C係為藉由前述的不織布所構成之構成構件中的任一者連續之連續薄片。 在製程S10，將疏水性墨水2配置於不織布10C。藉由使用塗佈裝置210將疏水性墨水2塗佈於不織布10C，配置疏水性墨水。塗佈疏水性墨水2的方法，可為柔版印刷，亦可為凹版印刷。塗佈裝置210係藉由上下一對滾子構成。藉由使不織布10C通過滾子間的間隙，使位於至少其中一方的滾子上之疏水性墨水2塗佈於不織布10C。疏水性墨水2為藉由紫外線(UV)硬化的墨水。因此，疏水性墨水2係包含藉由紫外線(UV)硬化的材料。 在製程S20，係進行對於至少配置有疏水性墨水2的墨水區域IR，照射紫外線之製程。如圖10所示，使用照射裝置220，對墨水區域IR照射紫外線。在配置有疏水性墨水2的墨水區域IR，藉由照射紫外線，可將從照射裝置220到不織布10C之間的空氣加溫。藉由已被加溫的空氣，可將不織布的纖維間之空氣加溫，因此，可使不織布10C的蓬鬆度增加。但，在墨水區域IR，因照射紫外線，使疏水性墨水會硬化而乾燥。藉此，以疏水性墨水2使不織布10C的纖維彼此被接合，不織布10C的纖維彼此變得不易分離。藉此，即使墨水區域IR的不織布10C的纖維間的空氣被加溫，不織布薄片10的蓬鬆度也不易增加。又，藉由照射於墨水區域IR之紫外線的能量，係因能量被用於疏水性墨水的硬化，故，墨水區域IR的不織布10C的纖維間的空氣不易加溫。其結果，能夠將墨水區域IR的不織布10C之厚度作成較非墨水區域NR的不織布10C之厚度薄。 又，在製程S20，亦可對墨水區域IR的周圍的非墨水區域NR照射紫外線。藉此，在非墨水區域NR，紫外線能被變換成熱能，將不織布的纖維間的空間進一步加溫。藉此，在非墨水區域NR，可使不織布10C的蓬鬆度進一步增加。 再者，照射裝置220，不僅紫外線，亦可照射紅外線。藉此，由於能夠將不織布10C加溫，故，可將纖維間的空氣進一步加溫。又，不僅是照射裝置220，亦可藉由加熱裝置，將不織布10C的纖維間的空氣加溫。其結果，可使非墨水區域NR中之不織布10C的蓬鬆度進一步增加。 在製程S20，亦可對纖維的粗細度粗之側的面，配置疏水性墨水2。配置有疏水性墨水2之側的纖維的粗細度係較未配置有疏水性墨水2之側的纖維的粗細度粗。藉此，如圖10所示，當從配置有疏水性墨水2之面側照射紫外線時，纖維較粗者可增加蓬鬆度，因此，能夠增大凹部S的深度。其結果，藉由以凹部S使墨水部11周邊的通氣性提升，能夠彌補因疏水性墨水2造成容易降低的通氣性。 再者，在製程S10，因以一對滾子進行塗佈，所以不織布10C的蓬鬆度會因被一對滾子夾持而減少。再藉由製程S20，在非墨水區域NR，使不織布薄片10的蓬鬆度回復。另外，在墨水區域IR，不織布薄片10的蓬鬆度不用回復到較製程S10更前階段。 由於疏水性墨水2係藉由紫外線硬化的墨水，故，藉由照射紫外線，可使疏水性墨水乾燥。藉此，比起不照射紫外線而乾燥的情況，能夠縮短乾燥時間。其結果，不需要為了進行乾燥用而增長搬運路徑，能夠抑制製造裝置的大型化，並且亦可謀求製造時間的縮短。 然後，藉由切斷不織布10C，可製造能夠抑制吸收性物品1的通氣性惡化之不織布薄片10。使用所製造的不織布薄片10，能夠製造吸收性物品1。 (7)其他實施形態 以上，使用上述實施形態詳細說明了本發明，但，對該業者而言，本發明不限於本說明書中所說明的實施形態者。本發明在不超出申請專利範圍中的記載所限定的本發明的技術思想及範圍，能夠進行各種修正及變更加以實施。因此，本說明書的記載目的為舉例說明，並不是用來限定本發明。 例如，在前述第2實施形態，疏水性墨水2係配置於第二薄片45的肌膚面側T1，但，不限於此。疏水性墨水2亦可配置於第二薄片45的非肌膚面側T2。藉此，在吸收體50與第二薄片45之間容易形成凹部S(空間)，配合穿用者的動作，吸收體50能沿著穿用者的身體容易折彎成凸狀。其結果，吸收體50變得不易從穿用者的身體分離，可減低排泄物的洩漏。 前述實施形態、各變形例及其他實施形態之吸收性物品的結構，可適宜地進行組合。例如，對於第2實施形態的衛生棉，亦可與第1實施形態同樣地，使用具有疏水性墨水2之不織布薄片。(1) The outline of the embodiment is based on the description in this manual and the drawings, and at least the following items can be clarified. One aspect of the absorbent article is an absorbent article provided with a non-woven fabric sheet with hydrophobic ink. In a plan view of the non-woven fabric sheet, the non-woven fabric sheet is provided with: an ink area where the hydrophobic ink is arranged, and a non-woven fabric sheet. The non-ink area where the hydrophobic ink is arranged, and the thickness of the non-woven fabric sheet in the ink area is thinner than the thickness of the non-woven fabric sheet in the non-ink area. Thus, due to the difference in thickness, the non-woven fabric sheet in the ink area (hereinafter referred to as the ink portion) is in a more concave state than the non-woven fabric sheet in the non-ink area, and recesses are formed in the non-woven fabric sheet, that is, a space is formed. Air is easier to pass through space than non-woven sheets with entangled fibers. Therefore, by increasing the air permeability around the ink portion with the recessed portion, it is possible to compensate for the air permeability that is easily reduced due to the hydrophobic ink. As a result, it is possible to suppress the deterioration of the breathability of the absorbent article. According to an ideal aspect, the hydrophobic ink is arranged on one side of the non-woven fabric sheet in the thickness direction, and one side of the non-woven fabric sheet is provided with a recess that is more recessed in the thickness direction than the periphery of the ink area. Recess. Since the concave portion is provided on the side where the hydrophobic ink is arranged, air that is difficult to pass in the thickness direction due to the hydrophobic ink can pass in the planar direction within the concave portion. In addition, the side wall portion of the recessed portion is around the ink area, so air in the recessed portion can easily pass through the side wall portion and pass through the non-woven fabric sheet around the ink area. As a result, it is possible to suppress the deterioration of the breathability of the absorbent article. According to an ideal aspect, the fiber density of the non-woven fabric sheet in the non-ink area is lower than the fiber density of the non-woven fabric sheet in the ink area. As a result, since the gap between the fibers in the non-ink area is relatively large, it is easy for air to pass through the non-ink area around the ink area, and the air permeability around the ink area is improved, thereby making it possible to compensate for the hydrophobicity. The air permeability of the ink tends to decrease. According to an ideal aspect, the hydrophobic ink is arranged on one side of the non-woven fabric sheet in the thickness direction, and the thickness of the fibers on the one side of the non-woven fabric sheet is smaller than the fibers on the other side of the non-woven fabric sheet. The thickness is large. By increasing the thickness of the fibers on one side of the nonwoven fabric sheet (that is, the side where the hydrophobic ink is disposed), the gap between the fibers on the one side can be increased. Thereby, air can easily pass through the part close to the hydrophobic ink, and the deterioration of air permeability can be suppressed. According to an ideal aspect, the hydrophobic ink is arranged on one side of the non-woven fabric sheet in the thickness direction, and the non-woven fabric sheet has a pressing portion squeezed from the other side of the non-woven fabric sheet in the thickness direction. On the other side where the non-woven sheet is squeezed, the gap between the fibers becomes smaller due to the squeezing. Therefore, by arranging hydrophobic ink on one side of the non-woven fabric sheet that is less likely to become smaller even if squeezed than the other side, the portion close to the hydrophobic ink allows air to pass through easily and suppresses ventilation. Sexual deterioration. According to an ideal aspect, if there is a contact sheet that abuts on one side of the non-woven fabric sheet in the thickness direction, the hydrophobic ink is arranged on the one side of the non-woven fabric sheet. Since the non-woven fabric sheet in the ink area is thinner than the non-woven fabric sheet around the ink area, a gap (space) is easily formed between the non-woven fabric sheet and the abutting sheet in the ink area. As a result, in the ink area, it becomes easy to pass through the gap between the non-woven fabric sheet and the contact sheet, and it is possible to suppress deterioration of the air permeability of the absorbent article. In addition, since the hydrophobic ink is arranged on one side of the nonwoven fabric sheet that is in contact with the contact sheet, the hydrophobic ink does not directly contact the wearer's skin, and it is possible to prevent the hydrophobic ink from adhering to the wearer's skin. According to an ideal aspect, there is also a composite sheet having a contact sheet contacting one side of the non-woven fabric sheet in the thickness direction and the non-woven fabric sheet, and the composite sheet has the non-woven fabric sheet and the contact sheet. In the shrinkage area where the contact sheet shrinks, at least a part of the ink area overlaps the shrinkage area in the thickness direction. In at least a part of the ink area, the non-woven fabric sheet and the contact sheet are non-joined. Thereby, since the non-woven fabric sheet and the abutting sheet are not joined in at least a part of the ink area, the non-woven fabric sheet and the abutting sheet can be separated in the thickness direction. In at least a part of the ink area, when wrinkles are formed by the shrinkage of the shrinking area, the non-woven fabric sheet and the contact sheet become easy to separate, and the space between the non-woven fabric sheet and the contact sheet can be enlarged. As a result, it becomes easier for air to pass through the gap between the nonwoven fabric sheet and the contact sheet, and it is possible to suppress deterioration of the air permeability of the absorbent article. In addition, since the ink area has higher rigidity than the non-ink area, wrinkles are less likely to be formed in the ink area, and it is easier to maintain the state of the non-woven fabric sheet in contact with the contact sheet. Even in a state where the non-woven fabric sheet is in contact with the contact sheet, the recesses formed in the non-woven fabric sheet can compensate for air permeability. According to an ideal aspect, the non-woven fabric sheet has a folding portion for folding the non-woven fabric sheet; and an opposing portion facing and abutting against the folding portion, the folding portion At least a part of the hydrophobic ink is arranged at a position where the opposed portion and the hydrophobic ink overlap in the thickness direction. Thereby, at least a part of the hydrophobic ink in the folded portion is located in a region overlapping with the hydrophobic ink in the opposing portion in the thickness direction, and it becomes easy to form a larger space. As a result, it becomes easier for air to pass through the gap between the folded portion and the opposing portion, and it is possible to suppress deterioration of the air permeability of the absorbent article. According to an ideal aspect, the absorbent article has an absorber, which is arranged closer to the non-skin surface than the non-woven fabric sheet, and overlaps the ink area and the non-ink area in the thickness direction, and the hydrophobic The sexual ink is arranged on the non-skin surface side of the non-woven fabric sheet, and the fiber density of the non-woven fabric sheet in the non-ink region is lower than the fiber density of the non-woven fabric in the ink region. Since the hydrophobic ink is arranged on the non-skin surface side, the hydrophobic ink does not directly contact the wearer's skin, and it is possible to prevent the hydrophobic ink from adhering to the wearer's skin. In the non-ink area, since the thickness of the non-woven fabric sheet is relatively thick, the excrement easily touches the non-woven fabric sheet in the non-ink area, and the inhalation of excrement can be accelerated. In addition, since the fiber density of the ink area is high and the hydrophobic ink is arranged on the non-skin surface side of the non-woven fabric sheet, the entire surface of the non-woven fabric sheet on the skin surface side can suck excrement. Therefore, it is possible to prevent the absorption speed from decreasing. Also, in the ink area, even if the excrement is difficult to pass to the non-skin surface side of the non-woven fabric sheet due to the hydrophobic ink, the excrement can also move to the non-skin surface side of the non-woven fabric sheet through the non-ink area, so absorption can be suppressed Performance is reduced. According to an ideal aspect, the absorbent article has an absorber which is arranged closer to the non-skin surface than the non-woven fabric sheet and overlaps the ink area and the non-ink area in the thickness direction. The hydrophobic ink is arranged on the skin side of the non-woven fabric sheet, and the fiber density of the non-woven fabric sheet in the non-ink region is lower than the fiber density of the non-woven fabric sheet in the ink region. In the non-ink area, since the thickness of the non-woven fabric sheet is relatively thick, the excrement easily touches the non-woven fabric sheet in the non-ink area, and the inhalation of excrement can be accelerated. In addition, the excrement started to be sucked in the non-ink area can be sucked into the non-skin surface side of the ink area with high fiber density by capillary phenomenon, so that the rate of inhalation of excrement can be suppressed from decreasing. Since the hydrophobic ink is arranged on the skin surface side of the non-woven fabric sheet, in the ink area, excrement does not easily flow back from the non-woven fabric sheet to the skin surface side, and re-wetting back can be reduced. According to an ideal aspect, it also has: an absorber that is arranged closer to the non-skin surface side than the non-woven fabric sheet and overlaps the ink area and the non-ink area in the thickness direction; and has an absorbent body that abuts on the wearer In the skin surface sheet of the contact surface of the skin, the non-woven fabric sheet is arranged in the thickness direction between the skin surface sheet and the absorber. Since excrement can be quickly absorbed by the skin sheet, excrement does not continue to remain on the contact surface of the skin sheet, and therefore, leakage of excrement along the wearer's body can be suppressed. In addition, since the non-woven fabric sheet having hydrophobic ink is closer to the skin surface side, there is a skin surface sheet, so it is possible to prevent the hydrophobic ink from adhering to the skin of the wearer. According to an ideal aspect, with the boundary between the ink area and the non-ink area as a boundary, the thickness of the non-woven fabric sheet in the ink area is thinner than the fiber density of the non-woven fabric sheet in the non-ink area. By changing the thickness of the non-woven fabric sheet near the boundary between the ink area and the non-ink area, the side walls of the recesses can be provided without the need to arrange the hydrophobic ink. As a result, the air permeability around the ink portion can be improved, and therefore, the air permeability that is easily reduced due to the hydrophobic ink can be compensated. As a result, it is possible to suppress the deterioration of the breathability of the absorbent article. One aspect of the non-woven fabric sheet is a non-woven fabric sheet that has hydrophobic ink and is used in absorbent articles. It is characterized in that, in a plan view of the non-woven fabric sheet, the non-woven fabric sheet is provided with an ink area where the hydrophobic ink is arranged, And the non-ink area where the hydrophobic ink is not arranged, the thickness of the non-woven fabric sheet in the ink area is thinner than the thickness of the non-woven fabric sheet in the non-ink area. One aspect of the method of manufacturing a non-woven fabric sheet is a method of manufacturing a non-woven fabric sheet used in absorbent articles, which is characterized by: disposing a hydrophobic ink hardened by ultraviolet rays on the non-woven fabric manufacturing process; and disposing at least the aforementioned The process of irradiating the ink area of the hydrophobic ink with ultraviolet rays. In the ink area where the hydrophobic ink is arranged, by irradiating ultraviolet rays, the air between the device that irradiates the ultraviolet rays and the non-woven fabric can be heated. With the heated air, the air between the fibers of the non-woven fabric can be heated, so that the bulkiness of the non-woven fabric can be increased. However, in the ink area, the hydrophobic ink hardens and dries due to ultraviolet radiation. Thereby, the fibers of the non-woven fabric are joined to each other with the hydrophobic ink, and the fibers of the non-woven fabric are not easily separated from each other. Thereby, even if the air between the fibers of the non-woven fabric in the ink area is heated, the bulkiness of the non-woven fabric sheet is not easily increased. In addition, the energy of the ultraviolet rays irradiated to the ink area is used to harden the hydrophobic ink. Therefore, the air between the fibers of the non-woven fabric in the ink area is not easily heated. As a result, the thickness of the non-woven fabric sheet in the ink area can be made thinner than the thickness of the non-woven fabric sheet in the non-ink area. Thereby, it is possible to manufacture a non-woven fabric sheet capable of suppressing the deterioration of the breathability of the absorbent article.

The absorptive body 40 is arranged at least in the sub-crotch area S3. The absorptive body 40 may also be arranged throughout the front side area S1, the back side area S2, and the crotch area S3. The absorptive main body 40 is composed of the front exterior body 20 and the rear exterior body 30 as separate bodies, and is joined to the front exterior body 20 and the rear exterior body 30 in the front side region S1 and the rear side region S2, respectively. The absorbent body 40 (absorbent article 1) has an absorbent body 50. The absorber 50 has at least an absorbent core material. The absorbent core contains an absorbent material that absorbs liquid. The absorbent core material contains, for example, crushed pulp or super absorbent polymer (SAP), or a mixture of these. The absorbent core material is arranged at least in the sub-crotch region S3. The absorbent core material may be arranged in the front area S1 or may be arranged in the rear area S2. The absorbent core material extends in the front-rear direction L from the front side area S1 to the rear side area S2. The absorbent body 50 may also have a core material wrapping layer for covering the absorbent core material. The core material around the cladding layer sandwiches the absorbent core material in the thickness direction T. The core material wrapping layer is made of, for example, tissue paper, non-woven fabric, and the like. The absorbent body 40 has: a skin surface sheet 41 located on the skin side T1 of the absorber 50; a liquid impermeable sheet 42 located on the non-skin surface side T2 of the absorber 50; and a relatively liquid impermeable sheet 42 arranged on The main body sheet 43 closer to the non-skin surface side T2.

The main body sheet 43 may be hydrophobic, and may be formed of a non-woven fabric having hydrophobicity, for example. (3) Non-woven fabric sheet Next, the non-woven fabric sheet 10 will be described using FIGS. 2 to 5. The absorbent article 1 is equipped with the nonwoven fabric sheet 10 which consists of a nonwoven fabric. The non-woven fabric is, for example, any of hot-air non-woven fabric, spun-bonded non-woven fabric, water jet non-woven fabric, and the like. The nonwoven fabric sheet 10 is at least one of a first front sheet 25, a second front sheet 26, a first rear sheet 35, a second rear sheet 36, a center sheet 41A, a side sheet 41B, and a main sheet 43. The non-woven fabric sheet 10 has hydrophobic ink 2. In a plan view of the non-woven fabric sheet 10, the non-woven fabric sheet 10 is provided with: an ink region IR where the hydrophobic ink 2 is arranged; and a non-ink region NR where the hydrophobic ink 2 is not arranged. The hydrophobic ink 2 is arranged (coated) by printing, for example. The method of printing hydrophobic ink 2 may be flexographic printing or gravure printing. The hydrophobic ink 2 contains a material hardened by ultraviolet (UV). Examples of materials that are cured by ultraviolet light include urethane acrylate, acrylic resin acrylate, and epoxy acrylate. Whether or not the hydrophobic ink 2 contains a material that is cured by ultraviolet rays can be measured by the following method. First, using tweezers, the hydrophobic ink 2 is collected from the non-woven fabric sheet 10 (ink portion 11) in the ink region IR. Second, using a Fourier transform infrared spectrophotometer (FT-IR), the collected hydrophobic ink 2 is irradiated with infrared rays to measure the peak value of the functional group. Third, it is judged whether the measured peak value is consistent with the peak value of the conventional material cured by ultraviolet rays. When the measured peaks match, it can be determined that the hydrophobic ink is cured by ultraviolet rays. As shown in FIG. 2, the ink area IR has a first ink area IR1, a second ink area IR2, a third ink area IR3, and a fourth ink area IR4. The first ink region IR1 is provided on the non-woven fabric sheet 10 constituting the central sheet 41A. The second ink area IR2 and the third ink area IR are in the nonwoven fabric sheet 10 constituting the side sheet 41B. The second ink region IR2 is provided in the part where the three-dimensional wrinkles are arranged. The third ink area IR3 is provided in the part where the foot wrinkles are arranged. The fourth ink region IR4 is provided on the second front sheet 26 and the second rear sheet 36. Furthermore, the three-dimensional wrinkle system can stand up toward the skin surface side T1. The three-dimensional wrinkle system has: a standing portion that can stand up by the contraction of the first elastic member 65 that is stretchable in the front-rear direction L; and the side sheet 41B and the side sheet 41B are arranged closer to the non-skin surface side than the side sheet 41B The junction where the components of T2 are joined. The three-dimensional wrinkles are formed as walls by standing up, and can prevent excrement from moving to the outside in the width direction W. In addition, the foot gathers are arranged closer to the outside in the width direction W than the three-dimensional gathers, and are contracted by the contraction of the second elastic member 66 that is stretchable in the front-rear direction L. Foot wrinkles are in line with the wearer's foot circumference to prevent excrement from leaking from the absorbent article. The non-woven fabric sheet 10 has an ink portion 11 composed of the non-woven fabric sheet 10 in the ink region IR, and a non-ink portion 12 composed of the non-woven fabric sheet 10 in the non-ink region NR. The ink portion 11 has: an ink layer 11A in which the hydrophobic ink 2 exists; and a non-ink layer 11B in which the hydrophobic ink 2 does not exist. The ink layer 11A is constituted by the hydrophobic ink 2 and the portion of the nonwoven fabric sheet 10 where the hydrophobic ink penetrates. In this specification, [hydrophobicity] refers to the property that it is not easy to mix with water or to retain water, for example, the contact angle with ion-exchanged water is 80° or more. In addition, the contact angle with ion-exchanged water can be measured by the method described in [Initial contact angle measurement] in Japanese Patent Application Laid-Open No. 2005-324010. The hydrophobic ink 2 is arranged on one side of the non-woven fabric sheet 10 in the thickness direction T. As shown in FIG. Therefore, the hydrophobic ink 2, that is, the ink layer 11A can be arranged on the non-skin surface side T2 of the nonwoven fabric sheet 10 in the thickness direction T, and can also be arranged on the skin surface side T1 of the nonwoven fabric sheet 10 in the thickness direction T. As shown in FIG. 4B, FIG. 4C, and FIG. 5, on one side of the non-woven fabric sheet 10, a concave portion S that is recessed in the thickness direction T more than the periphery of the ink region IR is provided. That is, a concave portion S recessed in the thickness direction T from the side where the hydrophobic ink 2 is arranged is provided. In FIG. 4B and FIG. 4C, the recessed part S is recessed from the non-skin surface side T2 toward the skin surface side T1. In FIG. 5A, the recessed part S is recessed from the skin surface side T1 toward the non-skin surface side T2. In FIG. 5B, the concave portion S is the non-woven fabric sheet 10 on the skin surface side T1, which is recessed from the non-skin surface side T2 toward the skin surface side T1, and the non-woven fabric sheet 10 on the non-skin surface side T2 faces the non-skin surface side T1. Side T2 is recessed. As shown in FIG. 4B, the thickness Ti of the non-woven fabric sheet 10 (ie, the ink portion 11) of the ink region IR is thinner than the thickness Tn of the non-woven fabric sheet 10 (ie, the non-ink portion 12) of the non-ink region NR. For example, the ratio (Tn/Ti) of the thickness Tn of the non-ink portion 12 to the thickness Ti of the ink portion 11 is 0.85 or less. In this case, since the space formed by the recessed part S can be enlarged, the air permeability of an absorbent article can be improved. In addition, the ratio of thickness (Tn/Ti) may be 0.2 or more. In this case, it is not easy for the wearer to feel the step difference between the ink region IR and the non-ink region NR. Therefore, it is difficult to give a sense of discomfort to the wearer, and it is possible to suppress deterioration of the wearing comfort of the absorbent article 1. For example, when the thickness Ti of the ink portion 11 is 1.1 to 1.3 μm, the thickness Tn of the non-ink portion 12 is 1.6 to 1.8 μm. Furthermore, the total thickness of the ink portion 11 may not be greater than the total thickness of the non-ink portion 12. In the top view of the non-woven fabric sheet 10, the boundary between the ink region IR and the non-ink region NR (hereinafter referred to as the ink boundary) is taken as the boundary. The thickness Ti of the non-woven fabric sheet 10 in the ink region IR is lower than that of the non-ink region NR. The thickness of Tn is thin. In the side wall portion of the recess S, there is a portion that is not covered by the hydrophobic ink 2. It is preferable that not all the side walls of the recess S are covered by the hydrophobic ink 2. The bottom of the recess S is formed by the ink layer 11A, and is not formed by the non-ink layer 11B. That is, only the ink layer 11A constitutes the bottom of the recess S. Furthermore, in FIGS. 3 and 4A, please note that the arrangement location of the hydrophobic ink 2 (ink layer 11A) is shown in an easy-to-understand manner, not the thickness of the hydrophobic ink 2 nor the thickness of the non-woven fabric sheet 10. The thickness of the nonwoven fabric sheet 10 can be measured by the following method, for example. Using a digital microscope (for example, a digital microscope VHX-100 manufactured by KEYENCE CORPORATION), an enlarged image is taken from a direction perpendicular to the cut surface of the non-woven fabric sheet 10. The enlarged image is an image enlarged to a magnification that can image the entire thickness direction T of the nonwoven fabric sheet 10, and the magnification is, for example, 20 to 50 times. Based on the obtained enlarged image, the thickness of the non-woven fabric sheet 10 is measured. The enlarged image system may be image-processed for easy thickness measurement. The average of the thickness measured on the cut surface of 3 separate parts in the smooth part of the non-ink area NR (that is, the part that is not affected by pressing and printing) and the ink area IR. The value is taken as the thickness of the non-woven fabric sheet 10. The fiber density of the non-woven fabric sheet 10 in the non-ink region NR is lower than the fiber density of the non-woven fabric sheet 10 in the ink region IR. Therefore, the fiber density of the non-ink layer 11B of the ink portion 11 is lower than the fiber density of the non-ink portion 12. The fiber density of the nonwoven fabric sheet 10 can be measured by the following method, for example. Specifically, when measuring the fiber density of the nonwoven fabric sheet 10 in each of the ink region IR and the non-ink region NR, the following method can be adopted. First, the ink portion 11 and the non-ink portion 12 are cut into a size of 10 mm×10 mm and used as samples. Second, using a scanning electron microscope (manufactured by JEOL Ltd.: JCM-5100), the cross section of the sample parallel to the thickness direction T is enlarged and observed. The magnification is the magnification that can measure the cross-section of 30-60 fibers in one screen (for example: 150-500 times). Third, measure the number of cross-sections of fibers in the ink section 11 and the non-ink section 12 respectively. Specifically, the number of cross-sections of the fibers to be cut is calculated on the cut surface of a predetermined area. In the ink portion 11, the fibers are divided into an ink layer 11A and a non-ink layer 11B in the thickness direction T in order to avoid the influence of absorbing the hydrophobic ink 2, and the number of cross-sections of the fibers on the non-ink layer 11B is measured. When the non-woven fabric sheet 10 is formed by laminating a plurality of fiber layers, in the ink portion 11 and the non-ink portion 12 in the same fiber layer, the number of cut fiber sections is counted. Fourth, the number of cross sections of the obtained fibers is converted into the number of cross sections of fibers of about 1 mm 2 , and this is used as the fiber density (strips/mm 2 ). The measurement was performed at three locations, and the average of the measured values was used as the fiber density of the sample. In addition, as the fiber density, the number of fibers per unit area of a cross section parallel to the thickness direction T is used, but as the fiber density, the number of fibers per unit volume may also be used. The number of fibers per unit volume can be obtained, for example, by X-ray CT analysis. Although the numerical values of the fiber density per unit area and the fiber density per unit volume are different, the relative comparison of the fiber density (for example, the comparison of the size) becomes the same. In addition, the fiber density of the nonwoven fabric sheet 10 on one side where the hydrophobic ink 2 is arranged is lower than the fiber density of the nonwoven fabric sheet 10 on the other side where the hydrophobic ink 2 is not arranged. Thereby, the gap between the fibers on the side where the hydrophobic ink 2 is arranged can be increased, and the side where the hydrophobic ink 2 is arranged can easily allow air to pass through, and it is possible to suppress deterioration of air permeability. Furthermore, the fiber density in this case can be measured by the following method. For the surface of the non-woven fabric sheet 10 on one side where the hydrophobic ink 2 is disposed (for example, the non-skin surface side T2 of the skin sheet 41 in FIG. 4) and the non-woven fabric on the other side where the hydrophobic ink 2 is not disposed The surface of the sheet 10 (for example, the surface on the skin surface side T1 of the skin sheet 41 in FIG. 4) is imaged using an electron microscope or a microscope (for example, VHX-2000 manufactured by Keyence Corporation, etc.) to obtain an enlarged view of the fiber Like. Measure the area of fibers per unit area in the image. In this way, the area ratio of the fiber is calculated. Regarding the area ratio of the fibers as the fiber density, the fiber density of the nonwoven fabric sheet 10 on one side can be compared with the fiber density of the nonwoven fabric sheet 10 on the other side. The thickness of the fibers of the non-woven fabric sheet 10 on one side where the hydrophobic ink 2 is arranged is larger than the thickness of the fibers of the non-woven fabric sheet 10 on the other side where the hydrophobic ink 2 is not arranged. Therefore, the thickness of the fibers of the ink layer 11A or the non-ink layer 11B close to the ink layer 11A is larger than the thickness of the fibers of the non-ink layer 11B far from the ink layer 11A. The thickness of the fiber can be measured by the following method, for example. Obtain a magnified image of the fiber with an electron microscope or microscope (for example, VHX-2000 manufactured by Keyence Corporation, etc.), and measure the distance between two points corresponding to the diameter of the fiber shown in the image. get on. On the side of the non-woven fabric sheet 10 on one side where the hydrophobic ink 2 is disposed (for example, the non-skin surface side T2 of the skin sheet 41 in FIG. 4) and the non-woven fabric on the other side where the hydrophobic ink 2 is not disposed The surface of the sheet 10 (for example, the surface on the skin surface side T1 of the skin surface sheet 41 in FIG. 4) is measured multiple times (the number of times is based on 100). The average value of the measured fiber diameter is taken as the fiber thickness. Therefore, if the average value of the diameter of the fiber is larger, it is determined that the thickness of the fiber is larger. Moreover, when the hydrophobic ink 2 is arranged on the skin surface side T1, in the non-ink portion 12, the thickness of the fibers on the skin surface side T1 is larger than the thickness of the fibers on the non-skin surface side T2. In addition, the non-woven fabric sheet 10 has a press portion (not shown) that is pressed in the thickness direction T. In the ink area IR, the press part may not be provided. Therefore, in the nonwoven fabric sheet 10, a press part is provided only in the non-ink area NR. In the ink area IR, a press section can also be provided. The non-woven fabric sheet 10 has a pressing part that is pressed on the other side where the hydrophobic ink 2 is not arranged. Furthermore, the non-woven fabric sheet 10 may also have a pressing part that is pressed from the side where the hydrophobic ink 2 is arranged. In addition, the absorbent article 1 has a composite sheet 13. The composite sheet 13 includes: a non-woven fabric sheet 10 in which the hydrophobic ink 2 is arranged; and an abutting sheet that abuts on one side of the non-woven fabric sheet 10 in the thickness direction T. For example, as shown in FIG. 5A, when the composite sheet 13 is formed by laminating the first sheet 13A and the second sheet 13B in the thickness direction T, the first sheet 13A is a non-woven fabric in which the hydrophobic ink 2 is arranged. The sheet 10 and the second sheet 13B are contact sheets that contact one side of the non-woven fabric sheet 10 in the thickness direction T. The first sheet 13A and the second sheet 13B are joined by the joint B. As shown in FIG. 5A, the composite sheet 13 has a shrinkage area CR where the first sheet 13A (nonwoven fabric sheet 10) and the second sheet 13B (abutting sheet) shrink. In the shrinking area CR, the first sheet 13A and the second sheet 13B may be shrunk by elastic members contained in the composite sheet 13 (for example, waist elastic member WE, first elastic member 65, second elastic member 66, etc.). At least one of the first sheet 13A and the second sheet 13B may be a sheet-shaped elastic member to shrink the first sheet 13A and the second sheet 13B. As shown in FIG. 5A, at least a part of the ink region IR overlaps with the contraction region CR in the thickness direction T. At least a part of the ink region IR is that the first sheet 13A and the second sheet 13B are non-joined. Therefore, the joining portion B that joins the sheets to each other does not overlap with the ink region IR in the thickness direction T. The entire range of the ink region IR may be non-bonded. As shown in FIG. 4A, the non-woven fabric sheet 10 has a folded portion 10f in which the non-woven fabric sheet 10 is folded, and an opposing portion 10c facing the folded portion 10f and abutting on the folded portion 10f. The facing portion 10c is a portion of the non-woven fabric sheet 10 that is not folded. As shown in FIG. 5B, at least a part of the hydrophobic ink 2 in the folded portion 10f is arranged at a position overlapping with the hydrophobic ink 2 in the opposing portion 10c in the thickness direction T. Moreover, as shown in FIG. 4, the absorber 50 is arrange|positioned closer to the non-skin surface side T2 than the non-woven fabric sheet 10. As shown in FIG. The absorber 50 overlaps the ink region IR and the non-ink region NR in the thickness direction T. The hydrophobic ink 2 is arranged on the non-skin surface side T2 of the non-woven fabric sheet 10. Therefore, the ink layer 11A is arranged on the non-skin surface side T2 of the non-woven fabric sheet 10. As mentioned above, the fiber density of the non-woven fabric sheet 10 in the non-ink region NR is lower than the fiber density of the non-woven fabric sheet 10 in the ink region IR. Also, the fiber density of the non-woven fabric sheet 10 in the non-ink area NR near the ink boundary between the ink area IR and the non-ink area NR (for example, within 5 mm from the ink boundary), and the non-ink area separated by a predetermined distance from the ink boundary The difference in the fiber density of the non-woven fabric sheet 10 in the area NR (for example, the range of 10 mm to 15 mm from the ink boundary) is within 5%. Thereby, since the fiber density of the non-woven fabric sheet 10 in the non-ink region NR does not change significantly in a predetermined range from the vicinity of the ink boundary, the air permeability and absorption performance can be stabilized in the non-ink region NR. In addition, the fiber density of the non-woven fabric sheet 10 in the ink region IR near the ink boundary (for example, within 5 mm from the ink boundary) and the ink region IR separated by a predetermined distance from the ink boundary (for example, 10 mm to 15 mm from the ink boundary) The difference in the fiber density of the non-woven fabric sheet 10 is within 5%. Thereby, since the fiber density of the non-woven fabric sheet 10 in the ink region IR does not change significantly in a predetermined range from the vicinity of the ink boundary, the air permeability and absorption performance in the ink region IR can be suppressed from greatly deteriorating. As described above, in the absorbent article 1, due to the difference in thickness between the ink portion 11 and the non-ink portion 12, the non-woven fabric sheet 10 in the ink region IR is in a more concave state than the non-woven fabric sheet 10 in the non-ink region NR. Due to this difference in thickness, a recess S, which is a space, is formed in the non-woven fabric sheet 10. Here, in the ink layer 11A, due to the hydrophobic ink 2, the gap between the fibers may become smaller or clogged. Therefore, as shown in FIG. 4B, the amount of air passing from the ink portion 11 toward the concave portion S is reduced. In addition, since air is easier to pass through the space than the nonwoven fabric sheet 10 in which the fibers are entangled, the air that is difficult to pass in the thickness direction due to the hydrophobic ink 2 can pass in the plane direction P in the recess S. In addition, the side wall portion of the recessed portion S is around the ink region IR, so the air in the recessed portion S easily passes through the side wall portion and passes through the non-woven fabric sheet 10 of the non-ink portion 12. As a result, the air in the recessed portion S can pass through the non-ink portion 12 and can be easily exchanged with the outside. Therefore, by increasing the air permeability around the ink portion 11 with the recessed portion S, it is possible to compensate for the air permeability that is easily decreased due to the hydrophobic ink 2. As a result, it is possible to suppress the deterioration of the breathability of the absorbent article 1. In addition, the fiber density of the non-woven fabric sheet 10 in the non-ink region NR is smaller than the fiber density of the non-woven fabric sheet 10 in the ink region IR, and the gap between fibers in the non-ink region NR becomes larger. Thereby, in the non-ink area NR around the ink area IR, air becomes easier to pass, and the air permeability around the ink portion 11 is improved, thereby making up for the air permeability that is easily reduced by the hydrophobic ink 2. In addition, the thickness of the fibers of the non-woven fabric sheet 10 on one side (the ink layer 11A side) on which the hydrophobic ink 2 is arranged is smaller than that of the non-woven fabric sheet on the other side (the non-ink layer 11B side) on which the hydrophobic ink 2 is not arranged When the thickness of the fiber of 10 is thick, the gap between the fibers on one side can be increased. Thereby, in the portion close to the hydrophobic ink 2, air can easily pass through, and the deterioration of air permeability can be suppressed. In addition, when the non-woven fabric sheet 10 has a press section for pressing the other side (non-ink layer 11B side) where the hydrophobic ink 2 is not placed, the other side is pressed to reduce the gap between the fibers. . Therefore, by arranging the hydrophobic ink 2 on one side of the non-woven fabric sheet 10 that is less likely to become smaller even if squeezed than the other side, the hydrophobic ink 2 is arranged so that air can easily pass through the portion close to the hydrophobic ink 2 , Can suppress the deterioration of ventilation. In addition, with the ink boundary as the boundary, the thickness Ti of the non-woven fabric sheet 10 in the ink region IR is thinner than the thickness Tn of the non-woven fabric sheet 10 in the non-ink region NR. Therefore, the thickness of the non-woven fabric sheet 10 can be changed near the ink boundary. Thereby, the side wall part of the recessed part S can be provided from the place where the hydrophobic ink 2 is not arrange|positioned, and therefore, the air permeability which is easy to fall by the hydrophobic ink 2 can be compensated. As a result, it is possible to suppress the deterioration of the breathability of the absorbent article. In addition, as shown in FIG. 5A, when the hydrophobic ink 2 is arranged on the side where the second sheet 13B as a contact sheet is arranged, the recess S can be easily inserted between the first sheet 13A and the second sheet 13B. Form a gap (space). As a result, in the ink region IR, it becomes easy to pass through the space between the first sheet 13A and the second sheet 13B, and it is possible to suppress deterioration of the air permeability of the absorbent article 1. In addition, since the hydrophobic ink 2 is not exposed, the hydrophobic ink 2 does not directly contact the skin of the wearer, and it is possible to suppress the adhesion of the hydrophobic ink 2 to the skin of the wearer. Moreover, as shown in FIG. 5A, at least a part of the ink region IR is that the first sheet 13A and the second sheet 13B are non-joined. Thereby, since the first sheet 13A and the second sheet 13B are not joined in at least a part of the ink region IR, the first sheet 13A and the second sheet 13B can be separated in the thickness direction T. In at least a part of the ink region IR, when wrinkles are formed by the shrinkage of the shrinking region CR, the first sheet 13A and the second sheet 13B become easy to separate, and the gap between the first sheet 13A and the second sheet 13B can be enlarged. space. As a result, it becomes easier for air to pass through the gap between the first sheet 13A and the second sheet 13B, and it is possible to suppress the deterioration of the air permeability of the absorbent article. In addition, since the ink region IR has higher rigidity than the non-ink region NR, wrinkles are less likely to be formed in the ink region IR, and it is easy to maintain the state of contact between the first sheet 13A and the second sheet 13B. Even in the state where the first sheet 13A and the second sheet 13B are in contact, the air permeability can be compensated by the recess S formed in the first sheet 13A. In addition, as shown in FIG. 5B, at least a part of the hydrophobic ink 2 in the folded portion 10f is arranged at a position overlapping with the hydrophobic ink 2 of the opposing portion 10c in the thickness direction T. Therefore, in the ink portion 11 Areas that overlap each other become easier to form a larger space. As a result, it becomes easier for air to pass through the gap between the folded portion 10f and the facing portion 10c, and it is possible to suppress deterioration of the air permeability of the absorbent article 1. In addition, as shown in FIG. 4C, when the hydrophobic ink 2 is arranged on the non-skin surface side T2 of the non-woven fabric sheet 10, the entire surface of the non-woven fabric sheet 10 on the skin surface side T1 can suck excrement. In addition, in the ink region IR, even if the excrement E is difficult to pass to the non-skin surface side T2 of the non-woven fabric sheet 10 due to the ink layer 11A (hydrophobic ink 2), the excrement E can also pass through the non-ink portion 12 to the non-woven fabric sheet. Since T2 of the non-skin surface side of the product moves, it is possible to suppress the decrease in absorption performance. Especially when the fiber density of the ink portion 11 is lower than that of the non-ink portion 12, the excrement E sucked into the non-ink layer 11B can be sucked into the non-ink portion 12 by the non-capillary phenomenon. Prevent the absorption rate from decreasing. Furthermore, since it can penetrate the recessed part S and diffuse on the surface of the absorber 50, it can prevent that an absorption speed falls. In addition, the excrement E absorbed by the absorber 50 is not easily returned to the skin surface side T1 by the ink layer 11A, and therefore, rewetting can be reduced. (4) Second Embodiment Next, the second embodiment will be described with reference to Figs. 6 to 8. Fig. 6 is a schematic plan view of the absorbent article 1 viewed from the skin surface side. 7 and 8 are schematic cross-sectional views of the absorbent article 1 in the F7-F section in FIG. 6. FIG. 8 is a diagram illustrating the arrangement relationship of each member, and each member is displayed in a simplified manner. As an absorbent article of the second embodiment, a sanitary napkin is taken as an example, and the embodiment will be described. The absorbent article 1 is not limited to sanitary napkins for sanitary use, and may also be sanitary pads or pads for light incontinence. The absorbent article 1 is used by being fixed to a wearing article of a user. In addition, descriptions of the same parts as those of the first embodiment will be omitted. The absorbent article 1 has a pair of flaps 1W. The pair of flaps 1W extends outward in the width direction than the outer edge of the absorber 50 (absorbent core material) in the width direction W. Therefore, it extends from the center part of the front-rear direction L toward the both outer sides of the width direction W. As shown in FIG. In addition, the pair of flaps 1W can be folded when the absorbent article 1 is used. The absorbent article 1 has a skin surface sheet 41, a second sheet 45, an absorber 50, a liquid-impermeable sheet 42, and a back sheet 47. As shown in FIG. 3, in the thickness direction T, the skin surface sheet 41, the second sheet 45, the absorber 50, the back sheet 47, and the liquid-impermeable sheet 42 are laminated. The skin surface sheet 41, the second sheet 45, the absorber 50, the liquid-impermeable sheet 42, and the back side sheet 47 are joined and fixed by joining parts. As the joining portion, for example, an adhesive HMA such as a hot melt adhesive can be used. The second sheet 45 is arranged between the skin surface sheet 41 and the absorber 50. The second sheet 45 is a nonwoven fabric sheet, and examples thereof include an air-through nonwoven fabric, a spunbonded nonwoven fabric, and a water needle nonwoven fabric. In the present embodiment, the skin surface sheet 41 and the second sheet 45 are integrated by the adhesive HMA, and the absorber 50 is wound so as to wrap the end in the width direction W. The skin surface sheet 41 is attached to the non-skin surface side of the absorber 50, and is bonded and fixed to the bonding portion 84 with an adhesive HMA. The skin surface sheet 41, the second sheet 45, and the absorber 50 are integrated into the main body 80. In addition, in the adhesive HMA that joins and fixes each member to each other, it is not necessary to apply the adhesive to the entire area. In particular, by adjusting the amount, area, application pattern, etc. of the adhesive to be applied as the adhesive HMA between the skin face sheet 41 and the second sheet 45, it is possible to ensure that the main body part 80 is lower than a pair of main bodies described later. The flexibility of the joint 85 closer to the outside in the width direction W can improve the touch of the skin. The main body joining part 85 joins the main body 80 and the non-skin side sheet. In this embodiment, in the main body joining portion 85, an adhesive such as hot melt is used to join the non-skin surface side of the main body portion 80 and the skin surface side of the back sheet 47. As shown in FIG. 1, the body joint 85 has a continuous shape along the front-rear direction L. As shown in FIG. The body joint 85 is arranged at the ends of both sides in the width direction W. As shown in FIG. The non-skin side sheet may only be the liquid-impermeable sheet 42 or may be a combination of the liquid-impermeable sheet 42 and the back sheet 47. The skin surface sheet 41 has a pair of first folded portions 2h that have side ends on both sides in the width direction W folded toward the non-skin surface side T2. The pair of first folded portions 2h are joined to the back side sheet 47 by the main body joining portion 85. The widthwise front ends of the pair of first folded portions 2h are located closer to the inner side in the width direction W than the outer edge of the main body joint 85. Thereby, the front end (edge) of the skin surface sheet 41 (1st folded part 2h) is not exposed. Therefore, since the front end of the skin sheet 41 does not touch the wearer's skin, it is possible to suppress deterioration of the skin touch. The second sheet 45 has a pair of second folded portions 3h that are folded toward the non-skin surface side T2 with side ends on both sides in the width direction W. The back side sheet 47 is a hydrophobic sheet member, and examples thereof include an air-through nonwoven fabric, a spunbonded nonwoven fabric, and a water needle nonwoven fabric. The non-skin side of the absorbent article 1 (that is, the non-skin side of the liquid-impermeable sheet 42) is provided with a central adhesive portion 8 coated with an adhesive or the like. When the absorbent article 1 is in use, the central adhesive part 8 is adhered to the skin side of wearing articles such as underwear, so that the absorbent article 1 is fixed to the underwear or the like. Similarly, on the non-skin side (the non-skin surface side T2 of the liquid-impermeable sheet 42) in the thickness direction T of each flap 1W, a flap adhesive portion 9 is provided. The absorber 50 is a member that absorbs excrement and holds it inside. In this embodiment, as shown in FIGS. 3, 4, and 6, the absorber 50 has a first absorbent core material 51A, a second absorbent core material 51B, and a cover sheet 52. The first absorbent core material 51A has the same structure as the absorbent core material of the first embodiment. The second absorbent core 51B is a sheet-like member in which a super absorbent polymer (so-called SAP), which is a liquid-absorbent granular material, is sandwiched by liquid-permeable sheets such as tissue paper from the skin side and the non-skin side, respectively. The cover sheet 52 is a liquid-permeable sheet member, and examples thereof include an air-through nonwoven fabric, a spunbonded nonwoven fabric, and a water needle nonwoven fabric. The cover sheet 52 is sandwiched between the first absorbent core material 51A and the second absorbent core material 51B. As shown in FIG. 8, the second sheet 45 has hydrophobic ink 2. Thereby, since the excrement can be quickly absorbed by the skin surface sheet 41, the excrement does not remain on the contact surface of the skin surface sheet 41 continuously. Therefore, it is possible to prevent excrement from leaking along the wearer's body. In addition, since the skin surface sheet 41 is located closer to the skin surface side T1 than the second sheet 45 having the hydrophobic ink 2, it is possible to prevent the hydrophobic ink 2 from adhering to the skin of the wearer. As shown in FIG. 6, the hydrophobic ink 2 can also be used to design the absorbent article 1. The hydrophobic ink 2 is arranged on the skin surface side T1 of the second sheet 45. Thereby, compared with the case where the hydrophobic ink 2 is arranged on the non-skin surface side T2 of the second sheet 45, the design can be recognized more easily. (5) Modification example Next, using FIG. 9, the modification example will be described. Fig. 9 is a schematic cross-sectional view of an absorbent article of a modified example. Fig. 9 is an enlarged schematic cross-sectional view of the central sheet 41A and the absorber 50, similarly to Figs. 4B and 4C. In addition, in the following description, descriptions that are the same as those described above are omitted. As shown in FIG. 9, the hydrophobic ink 2 is arranged on the skin surface side T1 of the non-woven fabric sheet 10. In the non-ink region NR, since the thickness of the non-woven fabric sheet 10 is relatively thick, the excrement E easily touches the non-woven fabric sheet 10 in the non-ink region NR, and the inhalation of the excrement E can be accelerated. In addition, the excrement E excreted in the ink region IR easily comes into contact with the non-ink portion 12 that is the side wall of the recess S, and can reach the absorber 50 via the non-ink portion 12. When the fiber density of the non-ink portion 12 is lower than the fiber density of the ink portion 11 (non-ink layer 11B), the excrement E that starts to be sucked in the non-ink area NR can be absorbed in the ink portion 11 with high fiber density. The inhalation is caused by the capillary phenomenon, and therefore, it is possible to suppress a decrease in the rate of inhalation of excrement E. Furthermore, since the hydrophobic ink 2 is arranged on the skin surface side T1 of the nonwoven fabric sheet 10, in the ink region IR, excrement does not easily flow back from the nonwoven fabric sheet toward the skin surface side, and re-wetting back can be reduced. In addition, when the nonwoven fabric sheet 10 has a contact surface that abuts the wearer's skin, since the hydrophobic ink 2 is arranged on the bottom surface of the recess S, the hydrophobic ink does not easily adhere to the wearer's skin. (6) Manufacturing method of nonwoven fabric sheet Next, the manufacturing method of the nonwoven fabric sheet 10 is demonstrated using FIG. 10. FIG. FIG. 10 is a diagram for explaining the manufacturing method of the non-woven fabric sheet 10. Display the direction of conveying constituent parts in the manufacturing process as the conveying direction MD. As shown in Fig. 10, the nonwoven fabric 10C is conveyed in the conveying direction MD. The non-woven fabric 10C is a continuous continuous sheet of any one of the constituent members constituted by the aforementioned non-woven fabric. In the process S10, the hydrophobic ink 2 is disposed on the non-woven fabric 10C. The hydrophobic ink 2 is applied to the non-woven fabric 10C by using the application device 210 to arrange the hydrophobic ink. The method of coating the hydrophobic ink 2 may be flexographic printing or gravure printing. The coating device 210 is composed of a pair of upper and lower rollers. By passing the non-woven fabric 10C through the gap between the rollers, the hydrophobic ink 2 located on at least one of the rollers is applied to the non-woven fabric 10C. The hydrophobic ink 2 is an ink hardened by ultraviolet (UV). Therefore, the hydrophobic ink 2 contains a material hardened by ultraviolet (UV). In the process S20, a process of irradiating ultraviolet rays to at least the ink region IR where the hydrophobic ink 2 is arranged is performed. As shown in FIG. 10, the irradiating device 220 is used to irradiate the ink region IR with ultraviolet rays. In the ink region IR where the hydrophobic ink 2 is arranged, by irradiating ultraviolet rays, the air between the irradiation device 220 and the non-woven fabric 10C can be heated. With the heated air, the air between the fibers of the non-woven fabric can be heated, and therefore, the bulkiness of the non-woven fabric 10C can be increased. However, in the ink region IR, the hydrophobic ink is hardened and dried by irradiating ultraviolet rays. Thereby, the fibers of the non-woven fabric 10C are joined to each other with the hydrophobic ink 2, and the fibers of the non-woven fabric 10C are not easily separated from each other. Thereby, even if the air between the fibers of the non-woven fabric 10C in the ink region IR is heated, the bulkiness of the non-woven fabric sheet 10 is unlikely to increase. In addition, the energy of the ultraviolet rays irradiated to the ink region IR is used to harden the hydrophobic ink. Therefore, the air between the fibers of the non-woven fabric 10C in the ink region IR is not easily heated. As a result, the thickness of the non-woven fabric 10C in the ink region IR can be made thinner than the thickness of the non-woven fabric 10C in the non-ink region NR. In addition, in the process S20, the non-ink region NR around the ink region IR may be irradiated with ultraviolet rays. Thereby, in the non-ink region NR, the ultraviolet energy is converted into heat energy, and the space between the fibers of the non-woven fabric is further heated. Thereby, in the non-ink area NR, the bulkiness of the non-woven fabric 10C can be further increased. Furthermore, the irradiation device 220 can irradiate not only ultraviolet rays but also infrared rays. Thereby, since the non-woven fabric 10C can be heated, the air between the fibers can be further heated. In addition, not only the irradiation device 220, but also the heating device may heat the air between the fibers of the non-woven fabric 10C. As a result, the bulkiness of the non-woven fabric 10C in the non-ink region NR can be further increased. In the process S20, the hydrophobic ink 2 may also be arranged on the surface on the side where the thickness of the fiber is thick. The thickness of the fiber on the side where the hydrophobic ink 2 is arranged is larger than the thickness of the fiber on the side where the hydrophobic ink 2 is not arranged. Thereby, as shown in FIG. 10, when ultraviolet rays are irradiated from the side on which the hydrophobic ink 2 is arranged, the thicker fiber can increase the bulkiness, and therefore, the depth of the recess S can be increased. As a result, by increasing the air permeability around the ink portion 11 with the recess S, it is possible to compensate for the air permeability that is easily decreased due to the hydrophobic ink 2. Furthermore, in the process S10, since a pair of rollers are used for coating, the bulkiness of the non-woven fabric 10C is reduced by being clamped by the pair of rollers. Through the process S20, the bulkiness of the non-woven fabric sheet 10 is restored in the non-ink area NR. In addition, in the ink region IR, the bulkiness of the non-woven fabric sheet 10 does not need to be restored to an earlier stage than the process S10. Since the hydrophobic ink 2 is an ink hardened by ultraviolet rays, the hydrophobic ink can be dried by irradiating ultraviolet rays. Thereby, the drying time can be shortened compared to the case of drying without irradiating ultraviolet rays. As a result, it is not necessary to increase the conveyance path for drying, and it is possible to suppress an increase in the size of the manufacturing apparatus, and it is also possible to reduce the manufacturing time. Then, by cutting the non-woven fabric 10C, the non-woven fabric sheet 10 capable of suppressing the deterioration of the air permeability of the absorbent article 1 can be manufactured. Using the manufactured nonwoven fabric sheet 10, the absorbent article 1 can be manufactured. (7) Other Embodiments As mentioned above, the present invention has been described in detail using the above-mentioned embodiments, but for the industry, the present invention is not limited to the embodiments described in this specification. The present invention can be implemented with various modifications and changes without departing from the technical idea and scope of the present invention defined by the description in the scope of the patent application. Therefore, the purpose of the description in this specification is to illustrate and not to limit the present invention. For example, in the aforementioned second embodiment, the hydrophobic ink 2 is arranged on the skin surface side T1 of the second sheet 45, but it is not limited to this. The hydrophobic ink 2 may also be arranged on the non-skin surface side T2 of the second sheet 45. Thereby, a recess S (space) is easily formed between the absorber 50 and the second sheet 45, and the absorber 50 can be easily bent into a convex shape along the wearer's body in accordance with the movement of the wearer. As a result, the absorber 50 becomes difficult to separate from the body of the wearer, and the leakage of excrement can be reduced. The structure of the absorbent article of the foregoing embodiment, each modification example, and other embodiments can be appropriately combined. For example, for the sanitary napkin of the second embodiment, a non-woven fabric sheet having hydrophobic ink 2 may be used in the same manner as in the first embodiment.
