- an elastic yarn is used as a knitting yarn around which a polyamide filament represented by nylon 6 and nylon 66 is wound as a covering yarn.
- these polyamide-based fibers have lower hygroscopicity than natural fibers, and therefore, when used in stockings that are directly touched and worn on the skin, stuffiness or stickiness due to sweating from the skin occurs.
- the polyamide fibers have high chargeability, when used in stockings, skirts and the like are easily clinged, and there is a great problem in terms of comfort.
- a method of adding an organic polymer compound having a hydrophilic group in a post-treatment step during dyeing or after dyeing is common, but in this case, since it is inferior in washing durability, it is not a solution. It was enough.

Abstract
Description
また、ポリアミド系繊維は帯電性が高いため、ストッキングに使用した場合、スカートなどがまとわりつきやすく、快適性の点で大きな問題があった。吸汗加工としては、染色中または染色後の後処理工程において親水性基を有する有機高分子化合物を付加する方法が一般的であるが、この場合、洗濯耐久性に劣るため、解決策としては不十分であった。
また、特許文献2に代表されるコンジュゲート糸を使用する方法では、コンジュゲート糸に捲縮性がないことから、ウーリー加工を行う必要があり、生産性の面で問題があった。
本発明はこれを踏まえて、生産性・透明性・肌触りを犠牲とすることなく、吸水性、吸湿性、制電性、捲縮性、接触冷感性を有するストッキング用複合繊維を得ることを、その目的とする。
本発明に用いる繊維形成性樹脂は、溶融可能な繊維形成性樹脂であればよく、ナイロン6やナイロン66等のポリアミド、ポリエチレンテレフタレートやポリブチレンテレフタレート、ポリエチレンナフタレート、全芳香族ポリエステル、ポリ乳酸等のポリエステル、ポリエチレンやポリプロピレン等のポリオレフィン等、又はこれらを主成分とする重合体、更にはポリフェニレンサルファイド、ポリエーテルエーテルケトン等の熱可塑性重合体が挙げられる。中でも、強度が高く、薄くても耐久性が得られる点から、ポリアミド(特にナイロン6)を使用するのが好ましい。
HO-(CO-PA-CO-O-PE-O)n -H
(式中、PAはポリアミドのブロック(ハードセグメント)、PEはポリエーテルのブロック(ソフトセグメント)、nは繰り返し単位を示す。)
また、ポリアミド単位としては、ナイロン6、ナイロン6,6、ナイロン12等が、ポリエーテル単位としては、ポリエチレングリコール、ポリテトラメチレングリコール等が好適に用いられる。

図1及び図2に示す複合繊維は、偏心芯鞘型であり、図3に示す複合繊維は、外側の繊維形成性樹脂BがC型である繊維である。
ストッキング用としては、捲縮率を高くするために、図1及び図2に示す偏心芯鞘型の複合繊維とすることが好ましい。
ポリエーテルブロックアミド共重合物の表面への露出角度は5~90°であることが必要であり、5~80°であることが好ましい。露出角度がこの範囲であれば、吸水性、吸湿性、制電性、接触冷感性に優れ、また、生産性、染色性も良好である。
ストッキングを製造するにおいては、本発明の複合繊維を100重量%用いてもよいし、他の繊維と交編してもよい。また、天然繊維と混紡して用いても構わない。使用割合は、本発明の複合繊維を20~100重量%の割合で使用するのが好ましい。また、目付、ゲージなどは特に規定するものではなく、目的に応じて適宜設定すればよい。
