几种胶粉用于涤棉纱浆纱性能研究

Study on sizing performance of several gum powders to polyester cotton yarn

为了对聚酯浆料有一个综合性了解和评价,将醋酸酯淀粉分别与聚酯、PVA、聚丙烯酰胺(PAM)配伍,形成3种胶粉浆料.通过实验,对这3种胶粉浆料的浆液性能、浆膜性能等进行了测试分析,并对涤棉纱线进行上浆实验,对比分析了上浆后纱线的毛羽降低率、增强率、减伸率等性能指标,所得数据可作为纺织企业对聚酯胶粉浆料使用时的参考.

In order to obtain a comprehensive understanding and evaluation about polyester size, it is dis- cussed that acetic ester starch respectively mixed in proportion with polyester, PVA, polyacrylamide （PAM） and formed in three kinds of gum powder size. By many experiments, size performance and film properties of these size were tested and analyzed. The sizing experiment was carried on polyester cotton yarns. It was compared and analyzed that the sized yarn hairiness reducing rate, increasing rate, reduc- ing rate and other performance indicators. The data can be used as the reference when textile enterprise uses polyester gum powder size.
