Abstract
PURPOSE: A polymer mixture containing a vinyl polymer, cellulose acetate and a specific acrylic copolymer is wet spun and subjected to two-step drawing to produce title fiber with high water absorption, luster and dyeability with industrial advantage.
CONSTITUTION: (A) 50W98pts.wt. of a vinyl polymer, perferably of acrylonitrile or vinyl chloride, and (B) 50W2pts. of cellulose acetate are combined and (C) an acrylic polymer containing 5W30wt% of monomer of forumla I (X is R2, formula II; R1, R3 is H, methyl; R2 is H, ammonium, alkali metal; 1, m are 0W50 where 0<1+m≤50) is added to the above mixture in an amount of 0.5W50pts. per 100pts. of the mixture of (A) and (B). The resultant mixture is wet spun and subjected to primary drawing at a ratio of 2.5W8. The fiber swollen with water is dried at 100W180°C so that the water content comes down to less than 1wt%. Then, the secondary drawing is effected at a ratio of less than 3 to produce the objective fiber with a void volume of 0.05W0.75cm3/g.
