Abstract

Nitrile acrylic fiber manufacturing process, which has a developable spiral curl when heated and a degree of contraction of 5 to 20%, with a contractibility of at least 30 milligrams per denier when submerged in water at 98ºC, in those which have been spun simultaneously and stretched two or more dissimilar polymeric components, said polymeric components consist, respectively, predominantly, in acrylonitrile and differing from one another in terms of thermal contraction, and being arranged eccentrically about the axis of the fiber, characterized in that the stretched fiber is heated in the relaxed state and stretched again to 1.05 to 1.25 times its initial length at temperatures of 100 to 200º C.
