Description
本発明は、一定範囲の領域を一つの単位とする凹凸模様のある不織布に関する。より詳細には、特にワイパー用として、凹凸模様に起因する美観性を有し、かつ、好適な触感及び拭き取り性に優れた不織布である。また、その製法に関する。 The present invention relates to a nonwoven fabric having a concavo-convex pattern having a certain range of region as one unit. More specifically, it is a non-woven fabric that has an aesthetic appearance due to the uneven pattern and is excellent in tactile sensation and wiping property, particularly for wipers. Moreover, it is related with the manufacturing method.
不織布として、構成繊維同士が交絡によって形態保持しているスパンレース不織布がある。スパンレース不織布は、直接、肌に触れる用途、例えば、対人向けのウェットティッシュや使い捨てのおしぼり等に用いられたり、また、対物ワイパーとして、家具、自動車、床面等の清掃に使用されている。 As the nonwoven fabric, there is a spunlace nonwoven fabric in which the constituent fibers are held in shape by entanglement. The spunlace nonwoven fabric is used for direct skin contact, for example, for wet tissue for personal use, disposable towels, etc., and as an objective wiper for cleaning furniture, automobiles, floors and the like.
このようなスパンレース不織布に拭き取り性の改良や美観性を持たす為に、表面に模様を付与する事が要望される。模様を付与する方法としては、プリントによる樹脂転写や熱エンボスによる方法が挙げられるが、これらの方法は、スパンレース不織布の風合いを悪化させ、触感を損なったり、拭き取り性が低下するデメリットがある。 In order to provide such a spunlace nonwoven fabric with improved wiping properties and aesthetics, it is desired to provide a pattern on the surface. Examples of methods for imparting a pattern include resin transfer by printing and methods by heat embossing, but these methods have a demerit that deteriorates the texture of the spunlace nonwoven fabric, impairs the touch, and lowers the wiping property.
スパンレース不織布の風合いを維持し、かつ、模様が付与されてなるものとしては、高圧水流絡合処理の際に、開孔を有する支持体ネット上に繊維シートを載置して高圧水流を作用させることにより、開孔及び凹凸模様が付与されたスパンレース不織布が知られている。（特許文献１） In order to maintain the texture of the spunlace nonwoven fabric and the pattern is applied, the fiber sheet is placed on the support net having an opening to apply the high-pressure water flow during the high-pressure water entanglement treatment.

（不織布の製造）
次に本発明のスパンレース不織布の製造方法について説明する。
繊維ウェブは、カード法やエアレイ法などにより形成される。該繊維ウェブは、パラレルウェブ、クロスウェブ、ランダムウェブ、あるいはエアレイなどいずれであっても良く、特に限定されるものではない。
(Manufacture of non-woven fabric)
Next, the manufacturing method of the spunlace nonwoven fabric of this invention is demonstrated.
The fiber web is formed by a card method, an air array method, or the like. The fiber web may be any of a parallel web, a cross web, a random web, and an air lay, and is not particularly limited.
該凹凸模様を不織布に付与する方法としては、一定範囲の領域における平均的高さに差のある複数個の領域の組合せからなる織物を支持体として、該繊維ウェブの水流絡合処理を行う。当該水流絡合処理において、ウェブ構成繊維同士は三次元的に交絡させられるものの、該構成繊維は大きく移動しない為、不織布目付分布は、繊維ウェブを作成した時とほぼ同じ状態となる。即ち、該繊維ウェブの目付を、ほぼ均一に作成していれば、当該水流絡合処理後も、ほぼ均一な目付分布のスパンレース不織布が得られる。 As a method for imparting the concavo-convex pattern to the nonwoven fabric, the fiber web is hydroentangled with a woven fabric composed of a combination of a plurality of regions having a difference in average height in a certain range of regions as a support. In the hydroentanglement process, the web constituent fibers are entangled three-dimensionally, but the constituent fibers do not move greatly, so the nonwoven fabric basis weight distribution is almost the same as when the fiber web is created. That is, if the basis weight of the fiber web is made substantially uniform, a spunlace nonwoven fabric having a substantially uniform basis weight distribution can be obtained even after the hydroentanglement process.
しかしながら、水流絡合処理時に使用する支持体にある、平均的高さが異なる複数個の領域によって、不織布の各領域での平均厚み並びに密度に差を生じる事となり、不織布上に高密度領域(或いは低厚み領域)と低密度領域(或いは高厚み領域)が形成される。
この密度(厚み)差により、不織布上に明確な領域が外観的に認識される事となる。また、領域ごとに嵩高さが異なるため、さまざまな種類のゴミの拭き取り性に効果を発揮することとなる。即ち、当該不織布の凹凸模様において、凸部については、拭き取り対象物に接触して、汚れ等を拭き取る効果があり、凹部については、該汚れ等を捕獲する特徴を有している。
However, due to the plurality of regions having different average heights in the support used during the hydroentanglement treatment, a difference in the average thickness and density in each region of the nonwoven fabric results in a high density region ( Alternatively, a low thickness region) and a low density region (or high thickness region) are formed.
Due to this density (thickness) difference, a clear region on the nonwoven fabric is recognized in appearance. Moreover, since the bulk varies from region to region, it is effective for wiping off various types of dust. That is, in the concavo-convex pattern of the nonwoven fabric, the convex portion has an effect of wiping off dirt and the like by contacting the object to be wiped, and the concave portion has a feature of capturing the dirt and the like.
本発明における一定範囲の領域の形態は、四角形、格子状、スクエア状、多角形等が挙げられる。特に四角形は、その美観及び該当する支持体の製作容易性により好まれる。また、該不織布の領域の面積は、不織布の凹凸模様が目視で確認しやすくする為に、２５〜２５００mm2が好ましく、５０〜４００mm2がより好ましい。 Examples of the form of the region within a certain range in the present invention include a quadrangular shape, a lattice shape, a square shape, and a polygonal shape. In particular, a quadrangle is preferred due to its aesthetics and the ease of manufacturing the corresponding support. In addition, the area of the nonwoven fabric region is preferably 25 to 2500 mm 2 and more preferably 50 to 400 mm 2 in order to make it easy to visually confirm the uneven pattern of the nonwoven fabric.
また、不織布に形成される高密度領域と低密度領域は、山谷状に点在するものでもかまわないが、不織布全体の美観的及び拭き取り性の観点より、当該複数個の領域の組合せが規則的に配置されていることが望ましい。この場合、支持体上の当該複数個の領域の組合せが規則的に配置されていることが要求される。
特に、拭き取り性や外観上の美観、更に不織布の強度特性を考慮すると、高密度領域と低密度領域とは不織布の長さ方向、巾方向ともに交互に構成されることが望ましい。
In addition, the high-density region and the low-density region formed in the nonwoven fabric may be scattered in a mountain-and-valley shape, but the combination of the plurality of regions is regular from the viewpoint of the aesthetics and wiping property of the entire nonwoven fabric. It is desirable to be arranged in. In this case, it is required that the combination of the plurality of regions on the support is regularly arranged.
In particular, considering the wiping property, the appearance aesthetics, and the strength characteristics of the nonwoven fabric, it is desirable that the high density region and the low density region are alternately configured in both the length direction and the width direction of the nonwoven fabric.
不織布上の当該複数個の領域のうち、最小密度である領域の平均密度値が、最大密度である領域の平均密度値の２０％以上８０％以下であることが好ましく、その最大値の３０％以上７０％以下であることがさらに好ましい。８０％以下であれば、明確なる凹凸模様が発現される。また、密度差に起因する不織布凹凸差に物理的に汚れが引っかかると同時に付着しやすくなり、拭き取り性に効果を発揮する。さらに、汚れによっては、凹部分に汚れが保持され、再汚染を防ぐことが出来る。当該複数個の領域における最小密度である領域の平均密度値が、最大密度である領域の平均密度値の８０％を超える値であると、不織布表面が実質フラットになるため、意匠性が劣るようになるとともに、汚れに対して引っかかりにくく、十分な拭き取り性能を発揮しにくい場合があるし、一度拭き取った汚れが脱離等して再汚染する場合がある。また、最大密度である領域の平均密度値の２０％未満であると、不織布全体の強度特性が低下する等の問題が発生する。なお、本発明にいう平均密度値は、後述する方法により求めることができる。 Of the plurality of regions on the nonwoven fabric, the average density value of the region having the minimum density is preferably 20% or more and 80% or less of the average density value of the region having the maximum density, and 30% of the maximum value. More preferably, it is 70% or less. If it is 80% or less, a clear uneven | corrugated pattern will be expressed. Moreover, it becomes easy to adhere at the same time as dirt is physically caught on the unevenness difference of the nonwoven fabric due to the density difference, and exhibits an effect on wiping property. Furthermore, depending on the dirt, the dirt is retained in the concave portion, and recontamination can be prevented. If the average density value of the area that is the minimum density in the plurality of areas is a value that exceeds 80% of the average density value of the area that is the maximum density, the surface of the nonwoven fabric becomes substantially flat, so that the design is likely to be inferior. At the same time, it may be difficult to get caught by dirt, and it may be difficult to exhibit sufficient wiping performance, or dirt that has been wiped off may be detached and recontaminated. Further, if it is less than 20% of the average density value of the region having the maximum density, problems such as deterioration of strength characteristics of the entire nonwoven fabric occur. In addition, the average density value said to this invention can be calculated | required by the method mentioned later.
また、各領域の平均厚さについては、不織布上の該複数領域のうち、最小密度である領域の平均厚さが、最大密度である領域の平均厚さの１１０％以上１９０％以下であることが好ましく、更には１２０％以上１８０％以下であることが更に好ましい。厚み割合が１１０％未満であると、凹凸差が少なく、凹凸模様が不鮮明となり、種々のゴミへの多様な拭き取り特性が発揮できなくなる等の問題が発生する。逆に１９０％を超える場合、拭き取りの際の不織布と拭き取り対象面との抵抗が大きくなり、拭き取り効率に問題が発生することとなる。 Moreover, about the average thickness of each area | region, the average thickness of the area | region which is the minimum density among these several area | regions on a nonwoven fabric is 110% or more and 190% or less of the average thickness of the area | region which is the maximum density. Is more preferable, and it is further more preferable that they are 120% or more and 180% or less. If the thickness ratio is less than 110%, the unevenness difference is small, the uneven pattern becomes unclear, and various wiping characteristics for various kinds of dust cannot be exhibited. Conversely, when it exceeds 190%, the resistance between the nonwoven fabric and the surface to be wiped during wiping increases, and a problem occurs in wiping efficiency.
規則的に配置されている領域は複数個を組合せているが、単純な凹凸模様を希望する場合には、当該複数個が２個であることが好ましい。すなわち、本願発明の不織布は、高密度領域Ａと低密度領域Ｂとからなることが望ましい。 A plurality of regularly arranged regions are combined, but when a simple uneven pattern is desired, it is preferable that the number is two. That is, it is desirable that the nonwoven fabric of the present invention comprises a high density region A and a low density region B.
高密度領域をＡ、低密度領域をＢとすると、高密度領域と低密度領域とは不織布の長さ方向、巾方向ともにＡＢＡＢＡＢ・・・と交互に連続した構成とする不織布が、拭き取り性や外観上の美観、更に不織布の強度特性を加味すると望ましい。 When the high-density area is A and the low-density area is B, the non-woven fabric in which the high-density area and the low-density area are alternately continuous with ABABAB in both the length direction and the width direction of the non-woven cloth, It is desirable to take into account the aesthetic appearance and the strength characteristics of the nonwoven fabric.
本発明に使用される水流絡合処理の支持体は、一定範囲の領域における平均的高さに差のある複数個の領域の組合せからなる織物であるが、各領域での経糸と緯糸の織り方を異なるようにする事により、支持体の各領域に該当する不織布表面の模様は、異なった物となる。
支持体の織り方には、平織り、綾織、朱子織り等があるが、支持体において、隣り合った領域が、異なった織り方であると、その領域に該当する不織布の表面模様が異なる。この場合、該不織布において、前述「支持体上にある一定範囲の領域における平均的高さの差に起因する凹凸差」と「支持体の各領域の織り方に起因する模様」が相まって、不織布全体での凹凸模様は更に明確となり、美観的に好ましい。
The hydroentangled support used in the present invention is a woven fabric composed of a combination of a plurality of regions having a difference in average height in a certain range of regions, but wefts of wefts and wefts in each region. By making the directions different, the pattern on the surface of the nonwoven fabric corresponding to each region of the support becomes different.
There are plain weave, twill weave, satin weave, and the like as the weaving method of the support. When the adjacent regions are different weaves, the surface pattern of the nonwoven fabric corresponding to the region is different. In this case, in the nonwoven fabric, the above-mentioned “difference difference due to difference in average height in a certain range of region on the support” and “pattern resulting from the weaving method of each region of the support” are combined. The overall uneven pattern becomes clearer and is aesthetically preferable.
なお、本願発明の凹凸模様は、主として不織布の片側の面のみに発生し、もう片側の面の領域間の凹凸差は該不織布の領域の中で最も低密度な領域の厚みの１／５〜１／２０程度とフラットであり、例えばワイパー等で拭き取り面を特定したい場合にも、有用である。 The concavo-convex pattern of the present invention mainly occurs only on one side of the nonwoven fabric, and the concavo-convex difference between the regions on the other side is 1/5 of the thickness of the lowest density region in the nonwoven fabric region. For example, when it is desired to specify the wiping surface with a wiper or the like, it is useful.
また、不織布全体での凹凸模様は、不織布両面にて目視確認は出来るものの、主として凹凸模様が発生している面の方が明確な凹凸模様を有している。 Moreover, although the uneven | corrugated pattern in the whole nonwoven fabric can be visually confirmed on both surfaces of a nonwoven fabric, the surface where the uneven | corrugated pattern has mainly generated has a clear uneven | corrugated pattern.
本発明のスパンレース不織布全体の平均目付は、２０〜１００ｇ／m2であることが好ましく、特に、３０〜７０ｇ／m2がより好ましい。不織布全体の目付が２０ｇ／m2未満になると繊維量が少ない為、凹凸模様が不鮮明になる。また、１００ｇ／m2より大きい場合には、高圧水流処理において、充分な三次元交絡を形成する事が難しくなる。 The average basis weight of the total spunlaced nonwoven fabric of the present invention is preferably 20 to 100 g / m 2, in particular, 30~70g / m 2 is more preferable. When the basis weight of the whole nonwoven fabric is less than 20 g / m 2, the amount of fibers is small, and the uneven pattern becomes unclear. On the other hand, when it is larger than 100 g / m 2, it becomes difficult to form sufficient three-dimensional entanglement in high-pressure water flow treatment.
本発明の不織布は、種々のワイパーに用いることができ、ガラス、電気製品、家具、床面、ガスコンロ等の汚れの拭取りに使用する対物ワイパーやウェットティッシュや使い捨てのおしぼり等の対人ワイパーに使用できる。特にウェット状態で使用するウェットワイパーとして好適に使用することが出来る。 The non-woven fabric of the present invention can be used for various wipers, and used for interpersonal wipers such as objective wipers, wet tissues and disposable towels used for wiping dirt such as glass, electrical appliances, furniture, floor surfaces, gas stoves, etc. it can. In particular, it can be suitably used as a wet wiper used in a wet state.
本発明の不織布の両表面は、セルロース繊維により構成されているため、肌触りが良く、ウェットワイパーに含浸させた液体の液保持性が良好である。また、表面に付与された凹凸模様は、美観だけでなく、皮膚表面の拭き取り性にも寄与する。また、該不織布に含まれるポリエステル繊維は、不織布の嵩高性を保持する役割も担う為、ウェット状態であってもへたりが生じにくく、取り扱い性が良好である。更に該不織布に含まれる熱融着繊維は、前述ウェット状態でのへたり防止、不織布全体の強度、或いは、不織布凹凸模様の形態維持の役割を担っている。 Since both surfaces of the nonwoven fabric of the present invention are composed of cellulose fibers, the touch is good and the liquid retaining property of the liquid impregnated in the wet wiper is good. Moreover, the uneven | corrugated pattern provided on the surface contributes not only to aesthetics but also to the wiping property of the skin surface. Moreover, since the polyester fiber contained in this nonwoven fabric also plays the role which hold | maintains the bulkiness of a nonwoven fabric, even if it is a wet state, it is hard to produce sagging and its handleability is favorable. Furthermore, the heat-fusible fiber contained in the nonwoven fabric plays a role of preventing sag in the wet state, maintaining the strength of the nonwoven fabric as a whole, or maintaining the shape of the uneven pattern of the nonwoven fabric.
