HBP-HTC改性真丝织物活性染料染色性能研究

Research on reactive dyeing of silk fabric modified with HBP-HTC

超支化合物是一类具有特殊结构和性能的聚合物,合成简便,价格低廉,具实用价值,采用端氨基超支化合物季铵盐(HBP-HTC,表面富含季铵盐阳离子)对真丝织物进行阳离子改性处理,研究了改性后真丝织物的活性染料染色性能.结果表明:经HBP-HTC改性的真丝织物在无盐促染下有效地提高了活性染料的上染能力,并且获得了较好的匀染性,但对其色牢度和色光略有影响.

Hyperbranched compound was kind of polymer with special structure and characteristics, which was easy to be prepared, low cost and has practical value. The fabric was modified with the self-made quaternary ammonium salt of amino-terminated hyperbranched polymer （HBP-HTC, surface with abundant cationic qua- ternary ammonium salt imino group） and dyeability of the modified silk fabric was investigated. The results showed that the modified silk fabric has higher dye uptake in the absence of the electrolytes, and has good level-dyeing property, but the modification influenced the color fastness and the hue slightly.
