PURPOSE:To obtain the titled fiber having excellent feeling and washing resis tance, by applying a deodorizing component to swollen gel of an acrylic fiber after the drawing and water-washing steps in the wet-spinning of an acrylic synthetic fiber and drying and densifying the acrylic fiber gel. CONSTITUTION:The objective fiber can be produced by applying an effective deodorizing component to a porous swollen gel fiber containing preferably 2-30% cellulose acetate after the drawing and water-washing procedure and drying and densifying the applied gel fiber. The polymer constituting the fiber is preferably composed of >=80(wt)% acrylonitrile and <=20% vinyl monomer and a monomer containing sulfonic acid group. The effective deodorizing compo nent is preferably a compound extracted from the plant of Theaceae family and having the following properties. Ultraviolet absorption spectrum, absorption peak at 276+ or -2mmu (diluted to 1,000 times with water); boiling point, 180-200 deg.C (20mmHg); 20wt% propylene glycol solution exhibits refractive index of N<20>=1.418+ or -0.02, specific rotation of [alpha]<20>D=+0.007+ or -0.002, specific gravity of d<20>20=1.025+ or -0.02. |
