摘　　要：为提高棉织物的免烫效果,采用丝光、液氨、丝光—液氨以及液氨—丝光分别对漂白棉织物进行预处理,并对处理后织物进行潮交联整理,测试了织物的折皱回复性能和拉伸断裂性能,研究了不同预处理工艺对棉织物免烫整理效果的影响。结果表明:液氨处理可提升漂白织物的折皱回复性能和强力;液氨和丝光联合处理的工艺顺序影响处理后棉织物性能,“丝光—液氨”处理对织物折皱性能和强力的提升均高于“液氨—丝光”处理;液氨联合潮交联整理后织物折皱回复角最高,可达270.67°,其强力保留率为77.42%;“丝光—液氨”联合潮交联整理后织物强力保留率最高,可达82.97%,折皱回复角为266.17°;4种预处理联合潮交联可有效提升整理后织物强力保留率,同时达到较好免烫效果。In order to improve the anti-wrinkle effect of cotton fabrics,the bleached cotton fabrics were pretreated with mercerizing,liquid ammonia,mercerizing-liquid ammonia and liquid ammonia-mercerizing,respectively.Then the fabrics with different pretreatments were subjected to moisture crosslinking finishing.The wrinkle recovery performance and tensile breaking properties of all treated fabrics were tested.The effect of different pretreatments on cotton fabrics and their moisture crosslinking finishing were systematically investigated.The results show that the liquid ammonia treating improves the wrinkle recovery and strength.The order of liquid ammonia treating and mercerizing in combined treatment has a significant effect on the performance of treated fabrics.The improvement in the wrinkle performance and strength of the"mercerizing-liquid ammonia"treatment on bleached cotton fabrics was found greater than that of the"liquid ammonia-mercerizing".Fabrics with single liquid ammonia pretreatment and moisture crosslinking finishing presents the highest wrinkle recovery angle,which reaches 270.67°,and the strength retention rate is 77.42%.Fabrics with the combined mercerizing-liquid ammonia pretreatment and moisture crosslinking finishing have the highest strength retention rate,which is 82.97%,and the wrinkle recovery angle is 266.17°.The four pretreatments combined with moisture crosslinking finishing process offer the potential to improve the strength retention rate of treated cotton fabrics and to maintain satisfied anti-wrinkle performance.
