YBP可染丙纶树脂的研制及纺丝工艺研究

在聚丙烯中加入一种染色性能优异的高聚物进行共混纺丝,可改善丙纶可染性.考察了共混树脂(YBP)复配比、流变特性、热性能及可纺性.结果表明:改性剂添加量为6%时,适当调整纺丝拉伸工艺,可制得强度≥40 cN/tex,延伸度为40%～60%的 YBP 可染丙纶.在常压下沸染,用分散染料上色,其上色率≥82%.

STUDY ON THE PREPARATION OF DYEABILITY YBP RESIN AND ITS SPINNING PROCESS

The dyeability of PP fiber was improved by means of blend spinning with a kind of polyester having ex-cellent dyeability.The YBP compound ratio,rheologic property,thermal property and spinnability of YBPwere investigated.If 6% modifier was selected,the tenacity of YBP fiber is higher than 40cN/tex,and elon-gation at break is about 40%～60%.Dyed by disperse dyes under normal pressure,the coloring proportion ishigher than 82%.
