摘要
采用自制的端胺基超支化合物（HBP-NH2）对棉织物进行阳离子改性，研究棉织物活性染料无盐染色的可行性。分别对改性溶液中HBP-NH2浓度、pH值、浸渍时间、焙烘温度和染色前水洗等因素进行探讨，得出最佳无盐染色工艺：HBP-NH2浓度6g／L，pH值5．5—6．0，80℃烘干5min，120℃焙烘3min，热水清洗后采用活性染料无盐染色。试验表明，棉织物无盐染色可获得与未改性棉织物常规染色相当的K／S值和染色牢度。
The self-made amino-terminated hyperbranched polymer （HBP-NH2 ） was applied to modify cotton fabrics in order to achieve salt-free dyeing with reactive dyes. Factors of pH value, concentration of HBP-NH2, dipping time, curing temperature and washing process prior to dyeing on dyeing behaviors were discussed. Optimum conditions were defined as follows： cotton fabric was treated with 6 g/L HBP-NH2 at pH value 5.5 - 6.0, then dried at 80℃ for 5 min , cured at 120℃ for 3 min and rinsed with hot water. The modified dyeings had similar K/S value and fastness compared to those of the conventional dyeings, even no salt was added to the dye bath in modified fabric dyeing.
