In order to realize the immobilization of collagen, chitosan and sericin on the surface of polypropylene fabric, the fabric is treated by ammonia and nitrogen low temperature plasma to produce reactive groups, and then the epoxy compounds (ethylene glycol diglycidyl ether, trimethylolpropane triglycidyl ether) are used as crosslinkers for a bridging process. Single factor experiment is carried out to investigate the influence of crosslinking parameters (temperature, time and the dosage of crosslinker) on immobilization yield. Chemical composition changes on the surface of the treated samples is analyzed by infrared spectroscopy, which indicated that the ammonia plasma treatment can produce more active groups. The results showed that immobilization rate of samples crosslinked by ethylene glycol diglycidyl ether is superior to that of trimethylolpropane triglycidyl ether. It also can be found that the fabric had a better wettability and antimicrobial properties. The whiteness and comfort property of chitosan-polypropylene fabric decreased slightly.

使用等离子体预处理将功能性生物分子固定在聚丙烯织物上

为实现胶原蛋白、壳聚糖和丝胶在聚丙烯织物表面的固定化，织物经氨氮低温等离子体处理产生反应基团，再经环氧化合物（乙二醇二缩水甘油醚、三羟甲基丙烷三缩水甘油醚）用作桥接过程的交联剂。进行单因素实验以研究交联参数（温度、时间和交联剂用量）对固定化产率的影响。通过红外光谱分析了处理后样品表面的化学成分变化，表明氨等离子体处理可以产生更多的活性基团。结果表明，乙二醇二缩水甘油醚交联的样品固定率优于三羟甲基丙烷三缩水甘油醚。还可以发现该织物具有更好的润湿性和抗菌性能。壳聚糖-丙纶织物的白度和舒适性略有下降。
