直接染料无醛固色剂TF-234Y浓的性能及应用研究

摘要

A new concentrated direct dyes formaldehyde-free fixing agent TF-234Y was prepared in view of the existing problems in direct dyes fixing agents, the environmental protection and market demands in this paper. The test and analysis of the formaldehyde content, heavy metal ions content and aromatic amine content which can cause cancer etc. proved that the dense fixing agent TF-234Y contained no harmful substances. Experiment results showed that when the fixing agent was applied to the medium or deep color cotton knitted fabric and cotton/brocade/ammonia(80/18/2)blended fabric dyed with direct dyes, the dense fixing agent TF-234Y was able to bviously improve various color fastness and was more excellently than fixing agent Y. Especially the effect of the dense fixing agent TF-234Y on the handle and color change of after treated fabrics was much less than that of fixing agent Y.%　　针对目前直接染料固色剂存在的问题以及环保、市场需求，制备出了直接染料无醛固色剂TF-234Y浓。通过对甲醛、重金属离子、致癌芳香胺等指标的检测分析，证实TF-234Y浓不含有害物质，用其对直接染料所染的中、深色棉织物、棉/锦/氨（80/18/2）混纺织物进行固色并检测固色后织物的综合性能，发现TF-234Y浓可以明显提升染色物的各项色牢度，其固色性能优于固色剂Y，尤其是对染色物的手感、色差变化的影响比固色剂Y要小得多。
