Abstract

To improve the dyeability of polypropylene (PP) fibers, PP/poly(trimethylene terephthalate) (PTT) blend fibers with various PTT contents were prepared using a commercial pilot spinning apparatus. The PP/PTT blend fibers were melt-pressed at $260^{\circ}C$ and quenched in ice-water to form PP/PTT blend films, and the thermal properties of the blend films were analyzed. DSC analysis showed that the melting temperature of the PP in the blends was unaffected by PTT blending and that PP and PTT crystallized independently. However, the melt crystallization temperature ($T_{mc}$) increased slightly with increasing the PTT content in PP/PTT blends. Synchrotron WAXS analysis of the annealed PP/PTT blend films showed that the crystal structure of PP in the blend films was the $\alpha$-form irrespective of the presence of PTT. SEM showed that PTT existed as spherical particles in the PP/PTT blends and that the particle size increased with increasing PTT content, which indicates that PTT was immiscible with PP. This immiscibility helped enhance the dyeing properties of the blend PP fibers.
