【発明の属する技術分野】
本発明は生分解性合成繊維用紡績油剤及び生分解性合成繊維の処理方法に関する。ポリエステル、ポリアミド等から製造された合成繊維が様々な分野で広く利用されている。これらの合成繊維は、使用後、焼却処分や回収再生処理に供されるものもあるが、そのためには多大な手間と費用がかかるため、その多くは野山や海に放置されたり、埋立処分されているのが実情である。しかし、ポリエステルやポリアミド等から製造された合成繊維は生分解性が低いため、使用後、これらを野山や海に放置したり、埋立処分すると、環境障害、環境汚染、環境破壊等、様々な環境上の問題を引き起こす。そこで、このような問題を解決するため、セルロース誘導体、キチン・キトサン誘導体、乳酸重合体、乳酸共重合体等、生分解性の重合体から製造された合成繊維を用いることが考えられ、各種の生分解性合成繊維の開発が盛んに行なわれるようになっている。本発明は、かかる生分解性合成繊維用の紡績油剤及び生分解性合成繊維の処理方法に関する。
