天然彩色茧丝纤维的丝胶固着技术研究

Study on sericin fixation technology of naturally colored silk fiber

为更多保留天然彩色茧丝纤维丝胶中的色素,采用乙烯单体接枝和戊二醛交联相结合的方法对黄红色天然彩色茧丝进行处理,研究了交联和接枝处理以及接枝和交联次序对天然彩色茧丝增重率和色泽的影响。研究结果表明:交联和接枝处理增强了丝胶间或与丝素的结合力,能较好地保留天然彩色茧丝丝胶内的色素成分;而颜色的饱和度较未处理丝纤维低,颜色变暗,色调偏向绿光;先交联工艺对纤维K/S值和颜色特征值的影响较小,是一种较好的处理方法。

In order to better keep the pigments in the naturally colored silk fiber, this study discusses the effect on the weight gain rate and color of the yellow-red naturally colored cocoon filament with the glutaraldehyde cross-linking and vinyl monomer grafting treatment. The results point that： the grafting and cross-linking treatment can enhance the binding force between sericin and fibroin and better keep the pigments in the naturally colored silk fiber; at the same time, the color saturation is lower than that of the untreated silk fiber; the color turns dark and the color tone tends to be green. The first cross-linking technology fiber has little effect on the K/S value and color feature value. It is a good treatment method.
