中文摘要：为建立蚕丝接枝率的定量分析方法,使用甲基丙烯酰胺(MAA)单体对桑蚕丝进行接枝反应,得到一系列不同接枝率的接枝蚕丝纤维组样。分别应用热重和红外光谱分析技术对系列接枝蚕丝纤维进行表征与分析发现,在表征曲线中出现了新的特征峰,且随接枝率的增加,新特征峰面积逐渐增大。采用Origin9.1数学分析软件中的Gaussian分峰法分别对热重DTG曲线和红外吸收光谱曲线进行分峰、拟合,建立接枝率和新特征峰面积比值间的线性函数关系模型,并对已知接枝率的企业样品进行验证。结果表明,蚕丝接枝率的相对误差均小于5%,结合热重或红外光谱检测建立数学线性函数模型是一套测试蚕丝纤维接枝率的有效定量分析方法。

外文摘要：In order to establish a quantitative analysis method for grafting rate of silk,a series of grafted silk fiber(PMSF)samples with different grafting rates were obtained by the grafting mulberry silk with methylacrylamide(MAA)monomers.The PMSF samples were characterized and analyzed by thermogravimetric analysis and infrared spectroscopy.It was found that a new characteristic peak appeared in the characterization curve after grafting treatment,and the area of the new characteristic peak gradually increased with the increase of grafting rate.The Gaussian method of Origin9.1 mathematical analysis software was used for peak division and fitting of derivative thermogravimetric analysis curve and infrared radiation absorption spectrum curve respectively.A linear function model between grafting rate(weighing method)and the area ratio of corresponding new characteristic peaks was established,and the samples with known grafting rates provided by an industrial partner were verified.The results showed the relative error of grafting rate of silk was less than 5%,indicating that the establishment of the mathematical linear function model combined with thermogravimetric or infrared spectroscopy detection is an effective quantitative analysis method for the determination of the grafting rate of PMSF.
