摘　　要：为解决木棉纱在织造过程中开口不清、断头率高等实际生产问题,本文针对木棉和棉纤维的特性,采用相似相容的原理,选择PVA1299、氧化玉米淀粉、聚丙烯酸配制浆料.并采用L9(34)正交实验法,确定上浆工艺中的含固量、PVA和氧化玉米淀粉的比例、氧化玉米淀粉与聚丙烯酸类浆料配比、浆槽温度等4个因素,再考核其增强率、毛羽降低率、耐磨次数、减伸率、上浆率等5个指标,最终确定各因素随各水平的变化规律和最佳上浆工艺:含固量9%,PVA、氧化玉米淀粉和聚丙烯酸为1.5∶1∶0.04,最佳浆槽温度为95℃.In order to solve actual problem in kapok fabric production, special characteristics of kapok fiber and cotton fiber were studied for sizing, including water repellent and oil absorption based on carboxaldehyde radicals of kapok fiber. Solution and similitude theory was adapted to select out three sizes such as partially alcoholized PVA 1299, oxidized corn starch and polyacrylic acid. L9（3^4）orthogonal experiment method was adapted on three measures involved of solid content, proportion of PVA and core starch, temperature in sizing box. Then three indicators of strength enhancement rate, decrease rate of hairiness and number of abrasive resistance were tested. Finally, change rules from each measure to levels and optimal sizing process were given. The sizing process is as solid content was 9%, ratio of PVA, oxidized corn starch and polyacrylic acid is 1.5： 1： 0.04, best temperature in sizing box is 95℃.
