Preparation and Property Study of PTT/CAB Blend Fibers

摘要

Poly(trimethylene terephthalate) (PTT)/cellulose acetate butyrate(CAB) blend fibers were prepared through melt blending and spinning in this paper. The mechanical properties, dyeability, and hydroscopicity of PTT/CAB fibers were studied. The results indicated that the tensile strength of PTT/CAB blend fibers reduced slightly and the elongation at break increased with CAB content rising. And the dye uptake and moisture absorption percentage of PTT/CAB blend fibers increased as more CAB was added, i.e., in some degree, CAB added improved PTT fiber's dyeability and hydroscopicity.
