ACRYLONITRILE FIBERS, A PROCESS FOR PRODUCING ACRYLONITRILE FIBERS, AS WELL AS PRODUCING PREOXIDIZED FIBERS, FIBROUS ACTIVE CARBON OR CARBON FIBERS THEREFROM

摘要

Acrylonitrile fibers suitable for production of preoxidized fibers, fibrous active carbon and carbon fibers, which have thereon a water- soluble basic aluminum salt of the formula: ##EQU1##where (1) A, B and C stand for mutually different acid residues;PP(2) l and q are both an integer or decimal fraction larger than 0;P P (3) m, n and p are 0 or an integer or decimal fraction and make a total which is not zero;PP(4) l+mEm+nEn+pEp+q=6 (Em, En and Ep are the valence numbers of A, B and C, respectively); ##EQU2## in an amount of 0.005 to 5.0% by weight of aluminum element based on the fiber having the salt.
