乙内酰脲抗菌剂在真丝纤维上的应用

The application of hydantoin antibacterial agent to silk fabrics

采用水相接枝法和浸轧法将乙内酰脲抗菌剂接枝或固着在真丝纤维上,探讨了水相接枝工艺因素对真丝纤维增重率的影响,比较了不同整理工艺对织物染色K/S值的影响,并用红外光谱和扫描电子显微镜表征了接枝真丝纤维结构的变化.结果表明,乙内酰脲抗菌剂能在过硫酸铵的引发下与真丝纤维发生接枝共聚反应,而K/S值的变化则取决于整理方式,先染色后整理使K/S值下降,而先接枝后染色则K/S值增加.

The hydantoin antibacterial agent was grafted or anchored onto the silk fibers by grafting in aq. phase and padding process. The influences of the process factors in the grafting in aq. phase on the silk weighting were investigated. The K/S values of textile dyeing from different finishing processes were compared, and the IR spectra and SEM were used to symbolize the structure changes of the grafted silk fibers. The grafting polymerization of hydantoin antibacterial agent was shown to have happened on the silk fibers when initiated by ammonium persulfate. The K/S value changes depended on the finishing modes： dyeing before finishing lowered the K/S values, and the grafting followed by dyeing raised the K/S values.
