Abstract
A method of producing a highly shrinkable acrylic fiber by dissolving acrylic resin in a solvent, extruding the solution thus obtained in an aqueous coagulation bath, washing the resulting fiber with water to remove the solvent, drawing it hot in hot water, drying it, relaxing it by heating in the presence of water at a temperature higher than 110º C, hot stretching again in water at a temperature lower than 100º C, cooling the fiber in water, under tension at a temperature lower than 90º C and lower than that in the secondary bath of drawing in hot, preheating the fiber to a temperature between 90º C and the cooling temperature mentioned above, and then guiding the fiber to a curling machine to give it an appropriate degree of laughter, and then finally drying it below 95º C.
