本文将木薯淀粉进行酸解和羧甲基化反应，制得了酸解羧甲基复合变性淀粉，对其进行了红外表征和浆液、浆膜性能的测试，并通过涤棉高支高密织物的上浆对比试验研究其实际浆纱织造效果。试验结果显示：酸解羧甲基复合变性淀粉属于高浓低粘浆料，粘度热稳定性好，浆膜性能均优于一般变性淀粉，对涤棉粘附性好，浆纱耐磨性、毛羽贴伏性好，织机效率、合格品率高，布品平整柔软，可以作为一种优良的涤棉高支高密织物浆纱材料。

In this paper, the acidolysis carboxymethyl composite modified starch was prepared by acidolysis and carboxymethylation reaction of cassava starch. Its structure was characterized by IR, the size property and sizing film property were tested and the practical sizing and weaving effect were studied through sizing contrast test on polyester/cotton high-count-density fabric. The test results show that the sizing agent has high concentration and low but thermal-stable viscosity, and the size film performance is better than conventional modified starch. It has good adhesion to polyester/cotton fabric, good sizing abrasion resistance and hairiness coverage as well as high loom efficiency and quality rate.
