Abstract

In order to impart dyeablility on to Polypropylene fiber, PP/EVA blend in the form of fibers and film were preparared using melt blending process. Ethylene vinylacetate containing 28wt% of vinylacetate(EVA(28)) was used as a copolymer. In the study of mechanical properties, tenacity and initial modulus decreased with increasing EVA concentrations, whilst extension at break increased with increasing EVA contents. Their results in the dyeing behavior show that dye adsorption increased with increased EVA contents for both blend fibers and films. The extent of dye uptake of red dye to modified polypropylene fibers was greater than that of Blue and Yellow counterparts due to the difference behavior of dye particles in dyeing bath.
