Influence of Spinning Technology on Dye Uptake of Modified Polypropylene Fiber

摘要

By adding small amount of olefin polymer additive, the dyeability of polypropylene fiber can be improved.Research results show that the improvement of dyeing performance of modified PP fiber is mainly due to the formation of looser structure of PP matrix and the microchannels among additive particles in blended fiber. The dye uptake of drawn fibers decreases with drawing ratios obviously and changes with temperature of heat plate and heat roller a little.
