Abstract

The invention provides an apparatus and process for providing crosslinked fibers or tows with non-symmetrical crimps. The process requires preheating precursor fibers or tows so as to soften the fibers prior to passing the fibers or tows through a horizontal stuffer crimper box to impart a crimp. The crimped fiber is then passed through a heating zone without stress or tension whereby the fibers or tows are carbonized. <IMAGE>
