改性聚酯纤维用防活性染料沾色剂的制备及其适用性

Preparation and application of anti-reactive dye staining agent for modified polyester fibers

以聚乙烯吡咯烷酮K30、十六烷基三甲基溴化铵和脂肪胺聚氧乙烯醚为原料,采用最优化试验设计配制了一种阳离子染料可染聚酯纤维防活性染料沾色剂。研究了防沾色剂对染料水溶液光谱吸收性能的影响及其在活性染料染色中的普遍适用性。结果表明,聚乙烯吡咯烷酮K30、十六烷基三甲基溴化铵和脂肪胺聚氧乙烯醚复配物可有效减弱活性染料对聚酯沾色,质量比为5∶1∶5的复配物效果最好。防沾色剂对活性染料水溶液的光谱吸收曲线、最大吸收波长和吸光度无明显影响,且对活性染料具有良好的普遍适用性。

For cationic dyeable polyester fibers, an anti-reactive dye staining agent was prepared from polyvinylpyrrolidione K30, cetyl trimethyl ammonium bromide and polyoxyethylene alkyl amine by optimum experiment design. The effect of anti-staining agent on spectra absorbability of aqueous dye solution was studied, and its universal applicability in reactive dyeing was also discussed. The results show that polyester staining of reactive dyes can be effectively weakened by the compound of polyvinylpyrrolidione K30, eetyl trimethyl ammonium bromide and polyoxyethytene alkyl amine, and the best anti-staining effect can be achieved when their mass ratio was kept at 5：1 ： 5. Anti-staining agent has no visible effect on the spectra absorption curve, maximum absorption wavelength and absorbance of aqueous dye solution. And the anti-staining agent shows good universal applicability in reactive dyes.
