改性棉织物的涂料染色工艺探讨

Discussion on pigment dyeing of modified cotton fabric

采用PECH-amine对棉织物改性,自制低温自交联粘合剂为固色剂,探讨其在涂料染色中的应用性能.结果表明：棉织物经PECH-amine改性后,改变了棉纤维对涂料的吸附能力,使得涂料对棉纤维的上染率和染深性提高;经自制低温自交联粘合剂交联固着,改性棉织物的染色牢度和手感均较好.探讨了棉织物的改性及涂料染色工艺,优化的改性工艺为：改性剂4 g/L,烧碱6~8 g/L,浴比1∶30,80℃处理30 min,水洗至中性.优化的涂料染色工艺为：涂料〈8%（owf）时,浴比1∶20,中性条件下90℃染色50 min,取出,水洗,皂洗,水洗,烘干.

Cotton fabric was modified with PECH-amine.Using self-made low temperature self-crosslinking agent as fixing agent,the application property of fixing agent in pigment dyeing was discussed.The results showed that the PECH-amine modification of cotton fabric changed the adsorption ability of cotton fiber to pigment,which increased the dye uptake and color depth of pigment on cotton fibers.The fixation of self-made low temperature self-crosslinking agent brought about good color fastness and handle.The modification of cotton fabric and pigment dyeing technology were investigated,the optimal modification technology was as follows： 4 g/L of modifier,6~8 g/L caustic soda,1∶30 of liquor ratio,and dyed at 80 ℃ for 30 min,washed to neutral.The optimal pigment dyeing technology was as follows： pigment 8%（owf）,1∶20 of liquor ratio,dyed at 90 ℃ for 50 min under neutral condition,the sample was withdrawn,washed,soaped,washed and dried.
