微波法对真丝纤维的接枝改性研究

Study on the graft modification of silk fibers by microwave

采用微波法用柠檬酸对真丝纤维进行接枝改性,测试了改性纤维的形态结构和主要性能.结果表明:微波法可以在短时间内使柠檬酸接枝到真丝纤维表面;接枝后真丝纤维的断裂强度和延伸度基本不受影响;吸湿性和染色性得到提高.

Microwave was used in graft modification of silk fibers with citric acid. The morphological structures and main properties of the modified fibers were tested. The results showed that the microwave method could graft citric acid onto the silk fiber surface in a short time, that the strength at break and prolongation of the grafted silk fibers were not affected, and the hydroscopicity and dyeing property were raised.
