水解淀粉与乙二醛对棉织物的抗皱整理

采用水解淀粉与乙二醛复配整理剂对棉织物进行抗皱整理,通过正交试验,讨论水解淀粉、乙二醛和催化剂用量、焙烘温度和焙烘时间等因素对整理后棉织物折皱回复角提高率和断裂强力保持率的影响。得出最优整理工艺参数:淀粉质量浓度40 g/L、乙二醛质量浓度7 g/L、催化剂质量浓度40 g/L、焙烘温度140℃、焙烘时间5 min。在此最优工艺条件下,整理后棉织物的折皱回复角提高率为30%~45%,断裂强力保持率为88%~95%。

Crease-resistant finishing of cotton fabric with glyoxal and hydrolyzed starch

A plain weave cotton fabric was treated with the mixture agent of glyoxal and hydrolyzed starch to impart the fabric crease-resistant property.The influence of the amounts of hydrolyzed starch,glyoxal and catalyst,baking temperature and time on the fabric crease recovery angle and strength retention was discussed comprehensively through orthogonal experiment.The premium finishing technology was that,hydrolyzed starch(40 g/L),glyoxal(7 g/L),catalyst(40 g/L),baking temperature(140 ℃,) baking time(5 min.) Under these conditions,the crease recovery angle was increased by 30%～45%,and the breaking strength retention kept as high as 88%～95%.
