纯涤不倒绒碱减量染色一浴法工艺的应用

Application of one-bath process of alkali peeling and dyeing for un-falling polyester fluff

通过对传统纯涤不倒绒染整工艺的分析,根据蓬莱嘉信耐碱型分散染料能在强碱下染色的特性,实现了纯涤不倒绒碱减量染色一浴法。介绍了该工艺的配方、条件,列举了绍兴二印大生产的结果。探讨了适合纯涤不倒绒碱减量染色一浴法的分散染料以及能够控制其匀染的助剂,比较了一浴法工艺与传统工艺的综合成本,得到了较完善的一浴法工艺,避免了传统工艺中的庛病,减少了水、电、汽的用量,缩短了工时,减少了污染物的排放,且产品染后色泽纯正靓丽,悬垂度与手感俱佳。

Based on the analysis of traditional dyeing and finishing process of pure polyester un-falling fluff, as well as the dyeing characteristic of Penglai Jiaxin alkali resisting disperse dyes under strong alkali, one bath method of alkali peeling and dyeing for pure polyester no-falling-fluff was realized. The recipe and conditions of the one bath method were introduced, the results of mass production in Shaoxing Printing and Dyeing Co., Ltd. were enumerated. Disperse dyes, as as well auxiliaries used for level dyeing, applicable for pure polyester no-falling-fluff one-bath process of alkali peeling and dyeing were discussed. By comparing costs of one bath method and traditional process, a better one bath process was obtained. This process avoids the defects in traditional process, and is with lower water, electricity and gas consumption, as well as shorter time and little pollutant emission. Furthermore, the dyed fabric present pure vivid color with better drapability and handle.
