Document Type and Number:
WIPO Patent Application WO/2022/145940
Kind Code:
A1
Abstract:
The present invention relates to a method for producing para-aramid fibers, and a para-aramid produced therefrom. The method for producing para-aramid fibers involves: spinning, into filament form, a spinning dope including a particulate additive, and then performing a series of coagulation and washing steps to remove the particulate additive from the spinning dope and thereby form recesses and protrusions on the surface thereof; and inducing crosslinking by treating with a crosslinking agent. Thus, the present invention can provide para-aramid fibers that exhibit improved rubber adhesion while maintaining, at an excellent level, or further improving the intrinsic properties, such as the mechanical properties, of para-aramid fibers.
