Study on the dyeability and hygroscopicity of polypropylene/cellulose acetate butyrate fibers by melt blending

摘要

Polypropylene/cellulose acetate butyrate(PP/CAB) blend fibers were prepared through melt blending and spinning. The dyeability, hygroscopicity, mechanical properties were investigated. The results showed that additional CAB could improve the dyeability and hygroscopicity of PP fibers. With increasing amount of CAB, the dyeability and hygroscopicity was also increasing. The tensile strength and elongation at break exhibited reduced with increasing content of CAB.
