Abstract
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: EQU Al.sub.2 (OH).sub.l (A).sub.m (B).sub.n (C).sub.p (Cl).sub.q (I) where PA1 (1) A, B and C stand for mutually different acid residues; PA1 (2) l and q are both an integer or decimal fraction larger than 0; PA1 (3) m, n and p are 0 or an integer or decimal fraction and make a total which is not zero; PA1 (4) l+mEm+nEn+pEp+q=6 (Em, En and Ep are the valence numbers of A, B and C, respectively); ##EQU1## in an amount of 0.005 to 5.0% by weight of aluminum element based on the fiber having the salt.
