Abstract
Description
本発明は、引張強力に優れたビニロン短繊維を含むスパンレース不織布の製造方法に関するものである。 The present invention relates to a method for producing a spunlace nonwoven fabric containing vinylon short fibers having excellent tensile strength.
ビニロン繊維は、他の繊維に比べて高強度であることから、その性能を活かした用途として、セメント複合材の補強用繊維として用いたり、法面補強や盛土補強等の土木分野に補強用ジオグリットとして用いられている。 Since vinylon fiber has higher strength than other fibers, it can be used as a reinforcing fiber for cement composites as an application that takes advantage of its performance, or geogrit for reinforcement in civil engineering fields such as slope reinforcement and embankment reinforcement. It is used as.
また、ビニロン繊維は、水溶性繊維であることから、ケミカルレースの基布として用いられている。すなわち、ビニロン繊維からなる基布に刺繍をした後、ビニロン繊維からなる基布を溶かして刺繍だけ残して模様をつくるというものである。また、ビニロン繊維の水溶性という特定を活かして、嵩高の不織布を得る方法が提案されている（特許文献１）。すなわち、ビニロン繊維、主体繊維、熱バインダー繊維を混合して、不織ウェブを形成し、熱処理によって、構成繊維同士を熱バインダー繊維のバインダー成分によって熱融着させた後、ビニロン繊維を溶かして嵩高の不織布を得るのである。
本発明者は、ビニロン繊維が有する高強力を活かし、機械的強度に優れた不織布であって、かつ柔軟で肌触りの良好な不織布を得ることができないかと検討した。柔軟で肌触りの良好な不織布としては、接着剤や熱接着により繊維同士を結合するのではなく、高圧水流の作用によって繊維同士が交絡してなるスパンレース法を適用するのがよいため、ビニロン繊維からなる短繊維ウェブに高圧水流を施したところ、極めて強度の低い不織布しか得られなかった。そこで、ビニロン繊維が有する高強力を活かすべく、さらに検討を重ねた結果、ビニロン繊維に特定の繊維を特定量混合してスパンレース法を適用すると、機械的強度が飛躍的に向上することを見出した。本発明は、このような知見に基づくものである。 This inventor examined whether the nonwoven fabric which was excellent in mechanical strength, and was flexible and had the soft touch could be obtained using the high strength which vinylon fiber has. As a non-woven fabric that is soft and has a good touch, it is better to apply a spunlace method in which fibers are entangled by the action of high-pressure water flow rather than bonding fibers by adhesive or thermal bonding. When a high-pressure water stream was applied to the short fiber web made of the material, only a nonwoven fabric with extremely low strength was obtained. Therefore, as a result of further studies to make use of the high strength of vinylon fiber, it was found that the mechanical strength is dramatically improved by applying a specific amount of vinylon fiber and applying the spunlace method. It was. The present invention is based on such knowledge.
すなわち、本発明は、ビニロン短繊維とセルロース系短繊維とを、７０〜３０／３０〜７０（質量比）の割合で混合し、カード機によって開繊して短繊維ウェブを得、次いで得られた短繊維ウェブを有孔支持体に担持させ、短繊維ウェブ側より高圧水流を該短繊維ウェブに施して、該短繊維相互間を交絡させ、その後、乾燥することを特徴とするビニロン短繊維を含むスパンレース不織布の製造方法を要旨とするものである。 That is, the present invention is obtained by mixing vinylon short fibers and cellulosic short fibers at a ratio of 70 to 30/30 to 70 (mass ratio), and opening with a card machine to obtain a short fiber web. The short fiber web is supported on a perforated support, and a high pressure water stream is applied to the short fiber web from the short fiber web side so that the short fibers are entangled and then dried. The subject matter of the present invention is to produce a spunlace nonwoven fabric containing
本発明で用いるビニロン短繊維は、いわゆるポリビニルアルコールを水や有機溶剤等の溶媒に溶かした紡糸原液を紡糸、延伸して得られる繊維である。本発明で用いるビニロン短繊維は、カード機により開繊させて短繊維ウェブを得ることを要するため、機械捲縮が付与されたものを用いる。機械捲縮が付与されていないと、カード機にて繊維同士が抱絡せずに、短繊維ウェブを得ることが困難となる。また、ビニロン短繊維の単糸繊度は、１〜５デシテックス程度がよい。繊度が１デシテックス未満になると、カード機で開繊しにくくなり、一方、５デシテックスを超えると、繊維の曲げ剛性が高くなるため、高圧水流による作用によって繊維同士が良好に絡合しにくくなる。 The vinylon short fibers used in the present invention are fibers obtained by spinning and drawing a spinning stock solution in which so-called polyvinyl alcohol is dissolved in a solvent such as water or an organic solvent. Since the vinylon short fiber used in the present invention needs to be opened by a card machine to obtain a short fiber web, the one provided with mechanical crimping is used. If mechanical crimping is not applied, fibers are not entangled in the card machine, making it difficult to obtain a short fiber web. The single yarn fineness of the vinylon short fiber is preferably about 1 to 5 dtex. If the fineness is less than 1 dtex, it will be difficult to open with a card machine. On the other hand, if it exceeds 5 dtex, the bending rigidity of the fibers will increase, and the fibers will not be easily entangled by the action of high-pressure water flow.
本発明で用いるセルロース系短繊維は、木綿繊維、レーヨン繊維、リヨセル繊維等が挙げられる。なかでも木綿繊維を用いることが好ましい。木綿繊維を用いることにより、ビニロン短繊維と混綿した結果、得られる短繊維の不織布は、飛躍的に強力が向上し、大きな技術的効果を奏するためである。 Examples of the cellulose short fibers used in the present invention include cotton fibers, rayon fibers, and lyocell fibers. Among these, it is preferable to use cotton fibers. As a result of using cotton fibers and blending with vinylon short fibers, the resulting non-woven fabrics of short fibers are remarkably improved in strength and exhibit great technical effects.
本発明で用いるビニロン短繊維およびセルロース系短繊維の繊維長は、カード機で開繊しうる程度の長さであればよく、一般に、繊維長が１０〜１００ｍｍ程度のものを用いる。 The fiber lengths of the vinylon short fibers and the cellulose short fibers used in the present invention need only be long enough to be opened by a card machine, and generally have a fiber length of about 10 to 100 mm.
本発明では、まず、ビニロン短繊維とセルロース系短繊維とをカード機で混綿し、開繊する。カード機とは短繊維群を針布で梳る機械である。カード機の入口に絡み合ったビニロン短繊維群およびセルロース系短繊維群を投入すると、これらの短繊維群が針布で梳られ、カード機の出口から開繊および集積された状態のシート状物が排出される。排出されたシート状物は、そのままの状態で搬送され、または二層以上に積層され、または適宜折り畳まれ（クロスレイド等）、短繊維ウェブが形成される。短繊維ウェブの目付は、１５〜１００ｇ／ｍ2で程度であればよく、用途に応じて適宜選択するとよい。 In the present invention, first, vinylon short fibers and cellulose short fibers are mixed with a card machine and opened. A card machine is a machine that rolls a group of short fibers with a needle cloth. When a vinylon short fiber group and a cellulosic short fiber group intertwined at the entrance of the card machine are introduced, these short fiber groups are beaten with a needle cloth, and a sheet-like material in a state where the fiber is opened and accumulated from the exit of the card machine. Discharged. The discharged sheet-like material is conveyed as it is, or laminated in two or more layers, or appropriately folded (cross-laid, etc.) to form a short fiber web. The basis weight of the short fiber web may be about 15 to 100 g / m 2 , and may be appropriately selected depending on the application.
短繊維ウェブを形成した後、これに高圧水流を施す。高圧水流を施す際、短繊維ウェブは、有孔支持体に担持する。そして、高圧水流は、それを短繊維ウェブに十分付与するため、短繊維ウェブ側、すなわち、有孔支持体側の反対側から、施される。高圧水流は、孔径０．０５〜２．０ｍｍの噴射孔から、高圧力（たとえば、１．５〜４０ＭＰａ）で水を噴出させて得られるものである。高圧水流は、短繊維ウェブに一回または二回以上、施される。この高圧水流が、有孔支持体に担持されている短繊維ウェブに衝突すると、高圧水流のエネルギーが短繊維ウェブの構成繊維を運動させるエネルギーとなり、短繊維相互間を交絡させるのである。そして、短繊維ウェブに衝突した後には、有孔支持体の孔から下方へ水が排出されるのである。有孔支持体としては、得られる不織布の用途に応じて任意のものを採用すればよい。比較的平滑な表面の不織布を得る場合は８０〜１００メッシュの細目織物からなる有孔支持体を用いればよいし、不織布の表面に凹凸を付与する場合は、所定の目開きを有する荒目織物（１５〜２５メッシュ）からなる有孔支持体を用いることができる。なお、ここでいうメッシュとは、１インチ当たりの線の和を指し、例えば１００メッシュの織物は、１インチ当たり１００本の線が存在するものを指す。 After forming the short fiber web, it is subjected to a high pressure water stream. When applying the high-pressure water stream, the short fiber web is supported on the perforated support. Then, the high-pressure water stream is applied from the short fiber web side, that is, the side opposite to the perforated support side in order to sufficiently impart it to the short fiber web. The high-pressure water flow is obtained by ejecting water at a high pressure (for example, 1.5 to 40 MPa) from an injection hole having a hole diameter of 0.05 to 2.0 mm. The high pressure water stream is applied to the short fiber web one or more times. When this high-pressure water stream collides with the short fiber web carried on the perforated support, the energy of the high-pressure water stream becomes energy that moves the constituent fibers of the short fiber web, and the short fibers are entangled with each other. And after colliding with a short fiber web, water is discharged | emitted below from the hole of a perforated support body. What is necessary is just to employ | adopt arbitrary things as a porous support body according to the use of the nonwoven fabric obtained. In order to obtain a nonwoven fabric having a relatively smooth surface, a perforated support made of a fine woven fabric of 80 to 100 mesh may be used. In the case of providing irregularities on the surface of the nonwoven fabric, a coarse woven fabric having a predetermined opening. A perforated support made of (15 to 25 mesh) can be used. In addition, a mesh here refers to the sum of the line per inch, for example, the fabric of 100 mesh points out that 100 lines per inch exist.
高圧水流を施した後の短繊維ウェブには、水が含浸されているため、短繊維ウェブを絞って過剰な水分を除去した後、熱風乾燥機等に通して、残余の水を蒸発除去する。以上のようにして、スパンレース不織布が得られる。 Since the short fiber web subjected to the high-pressure water flow is impregnated with water, the short fiber web is squeezed to remove excess water, and then passed through a hot air dryer or the like to evaporate and remove the remaining water. . A spunlace nonwoven fabric is obtained as described above.
本発明に係るスパンレース不織布は、構成繊維同士が機械的に交絡することによって形態保持してなるものであるため、肌触りが良好で柔軟である。したがって、従来、スパンレース不織布が用いられていた用途、すなわち、生活資材等に良好に用いることができる。また、吸水性を有するセルロース系繊維を含有していることから、ワイパー等の拭き布等としても良好に用いることができる。また、ビニロン短繊維の高強度を活かして、産業資材や土木資材等に適用することも期待できる。 Since the spunlace nonwoven fabric according to the present invention is formed by mechanically interlacing the constituent fibers to maintain the form, it has a good touch and is flexible. Therefore, it can be satisfactorily used for applications in which a spunlace nonwoven fabric has been used, that is, for daily life. Moreover, since it contains the cellulosic fiber which has water absorption, it can be favorably used as a wipe such as a wiper. In addition, it can be expected to be applied to industrial materials and civil engineering materials by utilizing the high strength of vinylon short fibers.
本発明の方法によって得られたビニロン短繊維を含むスパンレース不織布は、特定量のセルロース系短繊維を特定量混綿して、スパンレース法によって得られたものであり、スパンレース不織布特有の柔軟性と肌触りの良好さを保持しながら、強度が顕著に向上するという効果を奏する。 The spunlace nonwoven fabric containing the vinylon short fibers obtained by the method of the present invention is obtained by blending a specific amount of cellulosic short fibers with a specific amount, and is obtained by the spunlace method. While maintaining good touch, the effect of significantly improving the strength is achieved.
以下、実施例に基づいて本発明を説明するが、本発明は実施例に限定されるものではない。本発明は、スパンレース法を適用して不織布を得る際に、ビニロン短繊維とセルロース系短繊維とを特定の比率で混綿した短繊維ウェブを用いることにより、ビニロン短繊維のみからなる短繊維ウェブやセルロース系短繊維以外の繊維を混綿した短繊維ウェブと比べて、格別顕著に引張強力が向上するという知見に基づくものとして、解釈されるべきである。 EXAMPLES Hereinafter, although this invention is demonstrated based on an Example, this invention is not limited to an Example. The present invention uses a short fiber web in which vinylon short fibers and cellulosic short fibers are blended at a specific ratio when a non-woven fabric is obtained by applying the spunlace method. It should be construed as based on the knowledge that the tensile strength is remarkably improved as compared with a short fiber web blended with fibers other than cellulose-based short fibers.
