摘　　要：制备不同端氨基超支化聚合物(HBP-NH2)用于真丝纤维改性,提高真丝织物用活性染料进行无盐染色的上染率和染色牢度。以二乙烯三胺与丙烯酸甲酯为原料,改变合成单体的反应时间(0～6 h),制备出不同的端氨基超支化聚合物HBP-NH2(0)～HBP-NH2(6)。通过红外光谱和氨基含量测试证明HBP-NH2中含有大量的氨基和亚氨基等碱性基团,热重分析显示HBP-NH2具有较好的热稳定性。将制备的7种HBP-NH2分别用于真丝织物的改性,改性后的真丝织物在以活性染料进行的无盐染色试验中,表现出较好的染色性能,其中以HBP-NH2(5)改性后的真丝织物具有较高的染色K/S值和较好的色牢度。将HBP-NH2作为真丝纤维改性剂,可以实现用活性染料对真丝织物进行无盐染色的目标。In this study, hyperbranched poly amide-amine （HBP-NH2） polymers with different terminal groups were pre- pared to modify silk fiber for improving the dye uptake and color fastness of silk fabric dyed with salt-free reactive dye. Diethylenetriamine and methylacrylate were used as material to prepare HBP-NH2 （0） -HBP-NH2 （6） which had different amino end groups by changing reaction time （0 -6 h） of the monomer. The results of Fourier transform infrared spectro- scopic analysis and amino content determination showed that there are a lot of alkaline groups including amino and imino groups in HBP-NH2. Thermogravimetric analysis indicated that HBP-NHz had good thermal stability. The prepared 7 kinds of HBP-NH2 were used for fiber modification of silk fabric respectively, and the modified silk fabric was then dyed with salt-free reactive dye. The results showed that the modified silk fabric had good dyeing property and the silk fabric modified by HBP-NH2 （5）had higher K/S value and color fastness. Salt-free dyeing of silk fabric with reactive dye couldbe realized by using HBP-NH2 as fiber modifier.
