新型防霉剂CM1在丝织品保护中的应用研究

为探讨新型防霉剂CM-1在丝织品保护中的效果,通过抑菌活性和模拟环境加速老化实验,检验了其用于丝织品保护中的生物活性,皿内抑菌实验表明防霉剂有很好的生物活性,且具广谱性。结合多种仪器分析,通过热老化、光老化、酸碱水解老化等方法验证防霉剂对丝织品后期安全性影响。结果表明,防霉剂能有效抑制丝织品褪色,红外光谱显示样品的化学结构没有变化,扫描电镜结果说明防霉剂可使样品对抗热老化,对样品表面有保护作用,拉力试验和X-射线衍射论证了防霉剂对丝织品的拉力强度和结晶度均没有影响。

Application of new fungicide CM1 in silk conservation

A new fungicide CM1 was tested for its bioactivity against mildew for use in silk conservation.Culture dish experiments shows that the fungicide has very good bioactivity and is broadspectrum.Accelerated ageing tests were also designed to test the fungicide for longterm use and to see whether it caused degradation of silk or not.Heat ageing,light ageing,and acid and base ageing were used in this evaluation.The change in physical and chemical properties of untreated and treated silk after ageing was assessed by different methods.The results show that the fungicide can inhibit color fading of most treated silk.Infrared Spectroscopy (IR) revealed no chemical change of fungicide treated and untreated silk after ageing by different methods.Scanning Electronic Microscopy (SEM) showed that the fungicide can protect silk from heat ageing.Xray diffraction (XRD) and tear strength testing showed no difference in physical properties between fungicide treated and untreated silks after ageing by different methods.
