Abstract

In order to develop dyeable polypropylene fibers, polypropylene-polar polymer blends and their blend fibers, which were prepared via melt blending of polypropylene(PP) with ethylene-vinyl acetate copolymer containing 28 wt% of vinyl acetate(EYA(28)) and 38 wt% of vinyl acetate (EVA(38)) and phenolic resin novolac (PRN), at various compositions, were studied. Solubility parameter, thermal property, flow behavior. mechanical property, morphology, and miscibility of the blends were investigated. The blends of PP/EVA(28) exhibited enough compatibility to give a blend having no clear phase seperation and had excellent fiber forming ability. It was found that additive polymers could be dispersed without phase separation in the order of EVA(28) > EVA(38) > PRN and they affected the mechanical properties of PP. PP/EVA(38) and PP/PRN blends showed considerable decrease in flow and mechanical properties compared to those of pure PP. But PP/EVA(28) blends did not show property.
