摘　　要：测试分析了醋酸酯淀粉的性能、特点及聚乳酸长丝的性能与温度的关系,对比分析了醋酸酯淀粉浆液性能及其浆膜性能,并对纤度为83 dtex的聚乳酸长丝进行了上浆试验。结果表明:聚乳酸长丝在温度达到60℃以上时,性能发生变化较大,而醋酸酯淀粉在60℃及以下时仍能保持较高的黏度稳定性,满足中低温条件下聚乳酸长丝的上浆工艺,浆丝效果良好。The performances and characteristics of starch acetate were researched and the relationship between the properties of PLA fiber and the temperature was analyzed.The acetate starch liquid properties and film properties,and the fineness 83 dtex poly lactic acid fiber filament sizing experiments were compared.The results show that the performance of poly lactic acid fiber filament changes greatly when the temperature is over 60 ℃, but starch acetate at 60℃ and below can still maintain a high viscosity stability and satisfy sizing process of poly lactic acid fiber filament under low temperature. The effect of finished filament is good.
