Abstract (en)
[origin: EP0032215A1] 1. Bicomponent fibres and threads of two components A and B, consisting of different acrylonitrile polymers arranged eccentrically to each other, having permanent three-dimensional crimp, characterised in that they consists of a more highly shrinkable component A, which consists of a polymer or a polymer mixture having a comonomer content of not more than 2% by weight, and a component B with lower shrinkage, which consists of a polymer having a comonomer content of 4-15% by weight, and in that they have a recovery power in the cold which enables them to still retain, after mechanical stress of 1 cN/dtex, at least 30% of the crimp which they had prior to the stress.
