摘　　要：针对人棉纱的特点,设计两组分别以K-2000和DS变性淀粉为主配制了2组浆料.分别对2组浆料及其交汇的性能及有关指标进行对比测试.并分别使用2组浆料对人棉纱进行上浆,对比分析上浆后纱线的毛羽降低率、增强率、减伸率等性能指标.实验结果表明,以K-2000为主取代PVA的浆料配方可以改善人棉纱的上浆性能.According to the viscose yarn properties ,two sets of sizing formula were developed ,which mainly added modified starch K-2000 and modified starch DS respectively .T he slurry and film properties were tested ,then the two formulations of the slurry were used on viscose yarn sizing respectively .The sized yarn hairiness decreasing rate ,strengthening enhancement ratio ,elongation reduction rate and other performance indicators are analyzed .The result shows that the sizing performance of viscose yarn is im-proved after using K-2000 size to replace PVA .
