涤纶亲水整理与分散染料同浴染色工艺研究

Research on Hydrophilic Finishing and Dyeing of Polyester Fabric in One Bath

以自制的新型聚酯聚醚共聚物为亲水整理剂,采用高温高压法,对涤纶织物进行亲水整理同浴染色。研究整理剂用量对分散染料上染率和织物亲水性、色差以及色牢度的影响。结果表明:低温型染料上染率几乎不受影响,而中、高温型影响较大;织物亲水性在用量为6%时达到最佳;中、低温型染料染色织物色差在用量小于6%时影响小,而高温型染料染色织物色差在用量小于4%时影响小;同浴染色未影响染色牢度。因此,只要选择适用的分散染料和适量的整理剂,涤纶亲水整理同浴染色是可行的。

In order to reduce energy consumption and emission in dyeing and finishing process, self made new type polyester polyether copolymer hydrophilic finishing agent and disperse dyes are used to finish and dye PET fabric in one bath by high temperature pressure dyeing method. The effect of dosage of finishing agent on dyeing uptake, hydrophilicity, washing durability, chromatism and color fastness of dyed PET fabric are studied. The results show： The effect of dyeing uptake of fabric dyed with finishing a- gent and low-temperature dyes is small, but, to medium and high-temperature disperse dyes, the effect is bigger. When the dosages of finishing agent is 6%, the hydrophilicity is good. To low and medium temperature dyes, when the dosage of finishing agent is less than 6%, the chromatism is small, to high-temperature dyes, when the dosage of finishing agent is less than 4%, the chromatism is small. And the color fastness is not affected. So dyeing and finishing of polyester fabric in one bath is advisable as long as suitable dyes and suitable amount of finishing agent are chosen.
