With the trend towards light weight worsted wool fabrics, yarn linear density becomes smaller and smaller and single yarns would have replaced traditional ply yarns in processing of wool fabrics. It is necessary to solve the difficulties of weaving by single yarn, and sizing is one of the most effective measures. Oxidized starch, PVA and polyacrylamide size are used to form a formula of mixed sizing, and 15 groups are designed via uniform design. Two main properties of abrasion resistance and hairiness have been selected to do regression analysis. The results show that the best proportion of mixing sizing is 43% of oxidized starch, 29% of PVA and 28% of polyacrylamide size.%随着毛纺产品的日益轻薄化,纱线线密度越来越小,在生产加工中单纱将取代传统的股线,因此必须解决单纱织造难题,而毛纱上浆是有效方法之一.采用氧化淀粉、聚乙烯醇(PVA)和聚丙烯酰胺组成的复配浆料,利用均匀设计方法设计了15种配方,选取耐磨性和毛羽作为主要质量指标,进行回归分析,得出各组分的影响,进而得出适合试样毛纱上浆的浆料最佳配比为氧化淀粉质量分数为43％、PVA质量分数为29％和聚丙烯酰胺质量分数为28％.
