Description
本発明は、アクリル繊維で構成されたパイル布帛及びその製造方法に関する。 The present invention relates to a pile fabric made of acrylic fibers and a method for producing the same.
天然毛皮の毛並みは、毛先に集束性がなく、ソフトでぬめり感を有するものであり、近年このようなパイル布帛が求められている。しかしながら、合成繊維を用いて天然毛皮の特徴を有するようなパイル布帛が種々検討されているが、毛さばき性が低く、いまだ十分満足すべき天然毛皮様のパイル布帛を得るに到ってはいない。 The natural fur has no bundling at the end of the fur and has a soft and slimy feeling. In recent years, such a pile fabric has been demanded. However, various pile fabrics having characteristics of natural fur using synthetic fibers have been studied. However, a pile fabric having a natural fur-like shape that has low hairiness and is still satisfactory has not yet been obtained. .
例えば、扁平型のアクリル系非収縮繊維と繊度が２．２ｄｔｅｘ以下のアクリル系非収縮繊維を用いることにより、毛さばき性とソフト性を両立させたパイル布帛が提案されている（特許文献１）が、天然毛皮並のソフトな風合いを得ることは難しく、かつパイル布帛の回復性がないという欠点がある。また、収縮性の異なる２種以上の収縮繊維を含有させることにより、刺毛のヘタリを防ぎパイル布帛の硬化を生じさせないという提案がある（特許文献２）が、天然毛皮の柔らかな風合いを得るまでには到っていない。 For example, by using a flat acrylic non-shrinkable fiber and an acrylic non-shrinkable fiber having a fineness of 2.2 dtex or less, a pile fabric having both bristle and softness has been proposed (Patent Document 1). However, it is difficult to obtain a soft texture similar to that of natural fur, and there is a drawback that the pile fabric has no recoverability. In addition, there is a proposal that, by containing two or more kinds of shrinkable fibers having different shrinkage properties, preventing stinging of the stab and not causing the pile fabric to harden (Patent Document 2), a soft texture of natural fur is obtained. It has not reached.
さらに、収縮性繊維と非収縮性繊維を混合し、その収縮性繊維の１次若しくは２次クリンプ数を変化させることにより、風合いを維持したまま製造工程の生産性を高めるという提案がある（特許文献３）が、この方法ではパイル布帛の回復性や生産性は得られるが、天然毛皮の持つ、優れた風合いを発現させることは困難である。 Furthermore, there is a proposal to increase the productivity of the manufacturing process while maintaining the texture by mixing shrinkable fibers and non-shrinkable fibers and changing the number of primary or secondary crimps of the shrinkable fibers (patent) Reference 3) shows that this method provides recovery and productivity of pile fabric, but it is difficult to express the excellent texture of natural fur.
