1. fibre bundle that constitutes by bi-component, acrylic silk basically, described silk comprises:

  • With the gross weight of silk first component that to be the about 20wt% of benchmark~

    about 80wt% be made of first polymer based on acrylonitrile andWith the silk gross weight is second component that the about 80wt% of benchmark~

    about 20wt% is made of second polymer based on acrylonitrile, described second component and described first component are extended jointly, and have bigger hydrophily based on first polymer of acrylonitrile than second polymer based on acrylonitrile;

    The feature of wherein said silk be always be punctured into about 25%~

    about 50%, and the level of dying is lower than approximately-8 on the alkalescence.
