摘要
采用弱酸性染料染锦纶,对一浴一步法和一浴两步法染色-固色这两种工艺进行了探讨,测试并分析了温度、固色剂种类、固色剂用量、pH值对染色性能的影响。结果表明,弱酸性染料染锦纶可以实现染色-固色同浴,减少了水和蒸汽的用量,缩短了染色时间,降低了染色成本;一浴一步法染色-固色工艺所得染色织物色牢度不及一浴两步法染色-固色工艺,而且工艺条件控制不好容易造成面料的固色斑;一浴两步法染色-固色工艺是可行的。
The two kinds of processes about dyeing and fixation in one bath for one step and one bath for two steps of polyamide dyed by weak acid dyes were discussed, and the effects of temperature, the kinds of fixation agent, the dosage of fixation agent and pH value on dyeing property were tested and analyzed. The results show that polyamide dyed by weak acid dyes can successfully employ dyeing and fixation in one bath, and it reduces the dosage of water and steam, shortens dyeing time and decreases dyeing costs; the color fastness of fabric dyed by the method of one bath for one step is not as good as that by one bath for two steps, and it can cause fixation spot when the control of process condition is not appropriately controlled; the method of Dyeing and Fixation in one bath for two steps is feasible.
