摘　　要：文章用环氧封端硅油(ETSO)与聚醚胺ED-600、聚醚胺T-403发生开环反应并进行乳化处理,制备了聚醚嵌段氨基有机硅抗皱整理剂,并对真丝织物进行抗皱整理正交试验,选择最优抗皱整理工艺。研究乳化剂占原料比例对聚醚嵌段氨基有机硅抗皱整理剂性能的影响,以及研究了聚醚嵌段氨基有机硅抗皱整理剂对真丝织物的抗皱整理工艺,探讨了整理剂质量浓度、固化温度和固化时间等因素对真丝织物折皱回复角的影响。通过正交试验得出最佳工艺条件为:聚醚嵌段氨基有机硅抗皱整理剂质量浓度20 g/L、固化温度110℃、固化时间5 min。整理后真丝织物具有良好的抗皱性能,急弹性回复角和缓弹性回复角分别为65°和103.4°、急弹性回复角增加率和缓弹性回复角增加率分别为39.2%和36.2%,经纬向断裂强力保留率分别为91.5%和90.6%、白度保留率为99.5%,整理后真丝织物的手感更加柔软、质地更加细腻,厚度无明显变化。此外整理后的真丝织物健康安全,甲醛测试报告为未检出,具有良好的抗皱性和耐洗性,且具有一定的疏水性能。Silk fabrics are widely popular due to their unique properties such as material luster,comfortable wearing,smooth,delicate texture,soft feel and good drapability.However,their easy wrinkling properties seriously affect the appearance of silk fabrics and limit their widespread application.Therefore,it is necessary to carry out anti-wrinkle finishing on silk fabrics to improve their anti-wrinkle performance.Meeting the wrinkle resistance requirements of silk fabrics during use has always been a hot research topic.In the early days,N-hydroxymethylamide resin finishing agents were commonly used for wrinkle resistance of silk fabrics.Although the finished fabric has a certain wrinkle resistance effect,the silk fabrics treated with such compounds have formaldehyde residue problems,which can pose a threat to human health.With the increasing living standards of modern people,the demand for environmentally friendly and green textile products continues to expand.The research on formaldehyde-free anti-wrinkle finishing agents has good prospects and demand.At present,the formaldehyde-free anti-wrinkle finishing agents that have been extensively studied mainly include polycarboxylic acids,epoxy compounds,glyoxals,organic silicon,and waterborne polyurethane.The carboxyl group,epoxy group and other reactive groups in epoxy terminated silicone oil react and crosslink with the active group of silk fibers,improving the wrinkle resistance of silk fabrics.At the same time,polysiloxane molecules can improve the problem of strength loss caused by stress concentration caused by cross-linking in the finished fabric,reducing the strength damage of the finished fabric.Polysiloxane molecular segments diffuse and tightly cover the surface of silk fabrics,while polyether and amino segments are tightly adsorbed on silk fibers.The cyclic polysiloxane segments are tightly arranged in the outermost layer of silk fibers,while the polyether segments restrict the movement of the polysiloxane segments on the fiber surface.At the same time,the polyet
