分散染料色浆免蒸化水洗印花工艺

Color Paste Free-Steaming and Free-Washing Printing Process of Disperse Dyes

传统分散染料印花工艺存在污水排放量大、色度深、难降解,且能源浪费大等问题,文中采用色浆免蒸化水洗工艺处理涤氨单面布,介绍了工艺配方及条件,测试了处理后织物的染色牢度、手感及亲水效果,进行生产实践并与传统分散染料印花工艺进行对比结果表明,批量生产中色浆免蒸化水洗工艺各项色牢度较好,且织物手感和亲水性优异,不仅可以替代传统的分散染料印花工艺,而且省去了蒸化、水洗两道工序,节约了大量的水资源和蒸汽资源,实现了零污水和零污泥排放,提高了企业的经济效益。

Traditional disperse dye printing process has problems such as large discharge of sewage, deep color, difficult to degrade, and high energy waste. In this paper, the color paste free-steaming and free-washing printing process was used to treat polyester and spandex single-sided cloth, and the formula and conditions were introduced .The dyeing fastness, hand feeling and hydrophilic effect of the treated fabric were tested, and the production practice was carried out, which was compared with the traditional disperse dye printing process. The results show that the color fastness of color paste free-steaming and free-washing printi ng process in production is better, and the fabric handle feel and hydrophilicity is excellent, which can not only replace the traditional disperse dye printing process, but also eliminate the steaming and washing, which saves a lot of water resources and steam resources, realizes zero sewage and zero sludge discharge, and improves the economic benefits of the enterprise.
