腈纶/铜氨纤维/羊毛混纺纱上浆问题研究

Study on sizing matters of acrylic/copper ammonia fiber/wool blended yarns

为寻找一种适合于腈纶/铜氨纤维/羊毛混纺纱上浆的浆料配方,以醋酸酯淀粉、聚丙烯酰胺、聚乙烯醇为原料设计了2种浆料配方,测试了浆料的浆液、浆膜和浆纱性能,对比分析了2种配方浆料的上浆率,混纺纱浆纱后的增强率、减伸率、增磨率及毛羽降低率等性能指标。结果表明,当浆料配方为聚乙烯醇1799、聚丙烯酰胺、醋酸酯淀粉、蜡片的占比分别为10%、30%、55%、5%时,更适于腈纶/铜氨纤维/羊毛混纺纱上浆,其浆膜的综合性能较好,浆液黏度及黏度热稳定性优异,浆纱各项性能均较佳。

In order to find a suitable sizing formula for copper ammonia fiber / wool / acrylic blendedyarns, two kinds of sizing formulas were designed by using acetate starch, polyacrylamide and PVA. Wetested properties of size, size film and sized yarn, and conducted a contrastive analysis on sizingpercentage, enhancement rate, reducing elongation rate, increased grinding rate, hairiness decreasingrate and other performance indicators between two formulas after sizing process. The results showed that itwas suitable for sizing of copper ammonia fiber / wool / acrylic blended yarns when sizing formulas of PVA1799, polyacrylamide, starch acetate and wax represent respective percentage of 10%, 30%, 55%and 5%. Therefore, we achieved better size film with comprehensive properties, excellent sizing viscosityand thermal stability, and best sizing properties.
