中文摘要：

研究了通过原子转移自由基聚合（ATRP）法接枝的共聚真丝，制备了大分子真丝引发剂，并用能谱（EDs）检测了真丝上溴的相对含量；然后将单体甲基丙烯酸二甲氨乙酯（DMAEMA）接枝到真丝上，用傅立叶转换红外光谱（FT-IR）、X-射线衍射和扫描电镜（TEM）等对接枝真丝进行了结构分析，并对接枝前后真丝的各项性能进行了测试．结果表明：DMAEMA已成功地接枝到真丝上，且接枝反应主要发生在纤维表面；接枝后真丝的白度、强力等性能均有所下降．与原样相比，染色性能也发生了变化，接枝后的真丝活性染料更容易上染．

英文摘要：

The silk grafted by atomic transfer radical polymerization （ATRP） was studied. A macromolecular initiator was prepared for the silk, and the relative content of bromine on silk was determined by EDS. Then dimethylaminoethyl methacrylate monomer （DMAEMA） was grafted onto the silk, and the products were analyzed for their structures by FT-IR, X-ray diffraction and TEM. The various properties of the grafted silk were also tested. The results showed that DMAEMA was successfully grafted onto the silk, and the grafting reaction primarily occured on the fiber surface, and the grafted silk had lowered whiteness and strength. The dyeing performance was also changed as compared to the control samples. The grafted silk was easier to be dyed with reactive dyes.
