阳离子改性对棉织物无甲醛耐久压烫效果的影响

为提高耐久压烫棉织物的性能,用阳离子改性剂对其进行处理,经红外分析证实了改性反应的发生。探索了经阳离子改性提高耐久压烫棉织物的染色效果且不影响染色织物折皱回复性的最佳工艺。通过测试织物折皱回复性、强力及其涂料、直接染料染色性能,表明棉织物经阳离子改性后对织物耐久压烫的折皱回复性有一定提高,可以减小织物的强力损失,且具有较好的耐洗性。对耐久压烫织物的可染性有较大提高,尤其对涂料染色效果改善明显。

Effects of cationic modification on non-formaldehyde durable press finished cotton fabric

In order to improve the properties of durable press finished cotton fabric,cationic modification of the cotton fabric was performed and modification reaction on the cotton was confirmed by infrared analysis.The optimal process of cationic modification of cotton fabric was investigated,which could improve the dyeability of durable press treated cotton fabric without affecting its wrinkle resistance.The wrinkle recovery angle,strength,dyeability with pigment and direct dyes of the cotton fabric were tested.The results indicated that the cotton fabric after cationic modification has the wrinkle recovery angle improved,less strength loss,and better washing fastness.The dyeability of the non-formaldehyde durable press finished cotton fabric after cationic modification was improved significantly,especially with pigment dyeing.
