METHOD FOR FABRICATING ARAMIDE STAPLE FIBERS WITH HIGH STRENGTH AND BULKINESS

摘要

PURPOSE: A method for fabricating aramid staple fibers is provided to continuously perform staple process and to improve productivity.;CONSTITUTION: A method for fabricating aramid staple fibers comprises: a step of preparing aramid filaments(10) with 300 g/d or more of elasticity; a step of preparing a tow without rolling the aramid filaments; a step of performing thermal treatment of the tow; a step of crimping the tow; and a step of cutting the tow. The aramid filament contains para-based aromatic polyamide. The method further comprises a step of adding a primary emulsion to the tow.;COPYRIGHT KIPO 2012
