摘要
用于涤纶低温染色的促进剂具芳香族酯类结构,利于聚酯纤维增塑和膨化;其芳环结构及其所具有的羟基和羧基,通过氢键又利于吸附和携载染料。将具有该结构的环保型促进剂BLB用作涤纶低温染色的促染剂。结果表明,在105℃保温60 min及pH值7的工艺条件下,染浴中添加2%(owf)BLB,可使上染率达到95%以上,促染效果明显,并具有良好的色牢度;在低温条件下,BLB能显著提高偶氮、蒽醌和杂环分散染料的提升性。
The accelerating effect of environmental-friendly accelerator BLB on disperse dyeing of polyester at low temperature was studied. As a result, it was showed that the BLB, with a concentration of 2%（o. w. f.）, could increase the dye-uptake up to 9.5% and dyed fabric with good color fastness under pH value 7 and 105℃ ×60min. Meanwhile, it was also found that the BLB could improve the building-up property of disperse dyes with the structures of azo,anthraquinone and heterocyclic ring under low temperature, showing good adaptability to different kinds of disperse dyes.
