High-strength modacrylic fibres, their preparation and use

摘要

Halogen-containing acrylic fibres composed of acrylonitrile copolymers containing at least 50% by weight of acrylonitrile and with halogen contents of 20 to 30% by weight, characterised by breaking strengths >/= 2.5 cN/dtex, E moduli >/= 400 cN/tex and elongations at break
