摘要
采用正交试验探讨了脂肪胺聚氧乙烯醚(1815)、亚甲基二萘磺酸钠(NNO)、平平加O和丙烯酸接枝淀粉对锦纶、棉织物染色性及防沾色性的影响.分析了染色过程中4种助剂对弱酸性染料上染锦纶及活性染料上染棉时上染性能和沾色性能的影响;分析了皂洗过程中4种助剂对弱酸性染料沾色棉和活性染料沾色锦纶的影响.研究结果表明:单独使用1815虽有一定防沾色效果,但会明显降低弱酸性染料染锦纶或活性染料染棉的上染率以及织物的表面色深度,但与助剂NNO或接枝淀粉共同使用时,在染色或皂洗过程中能较多降低弱酸性染料对棉或活性染料对锦纶的沾色,而对染料上染纤维的影响较小.
The influences of four assistants [fatty amine polyoxyethylene ether （1815）, sodium methylenebisnaphthalene sulfonate （NNO）, peregal O and acrylic acid grafted starch] on dyeing behavior and anti-staining of polyamide and cotton fabric were investigated by orthogonal experiments. During dyeing process, the effects of the assistants on dyeing performance of polyamide and staining of cotton using acid dyes, and dyeing performance of cotton and staining of polyamide using reactive dyes were analyzed. During soaping, the influences of the assistants on cotton staining of acid dyes and polyamide staining of reactive dyes were analyzed. The result indicates that 1815 has certain anti-stain effect, but it could distinctly reduce the dye uptake of polyamide dyeing of acid dyes, cotton dyeing of reactive dyes and the apparent color depth of fabric. But when it was used with NNO or grafted starch, they can reduce the staining of the acid dyes on cotton fabrics and reactive dyes on polyamide during the dyeing and soaping processes, and have little effect on fiber dyeing.
