家蚕丝素蛋白阳离子化及其对羊毛性状的影响
|
摘要
为提高羊毛织物的穿着舒适性,以碳化二亚胺(EDC)为激活剂激活家蚕丝素蛋白侧链上的羧基,使其与精胺反应得到阳离子化丝素蛋白,并将其整理到羊毛上,借助扫描电子显微镜、X射线衍射仪、傅里叶红外光谱仪、差示扫描热量仪对整理后的羊毛进行分析与表征。结果表明:整理后的丝素蛋白Zeta电位由-3. 58 m V上升到5. 41 m V;改性羊毛鳞片层表面被丝素蛋白膜包裹,其表面形成了更多的氢键和酰胺键,晶体结构更稳定,耐热分解性能提高,但力学性能下降;不同改性程度的家蚕丝素蛋白对羊毛结构的影响无明显差异,改性处理使羊毛酸性染料上染率下降。
In order to improve the wearing comfort of wool fabrics,1-( 3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride( EDC) was used as an activator to activate carboxyl group on the silk fibroin side chain to react with spermine. The cationized silk fibroin was then arranged on the finished wool fiber. The finished wool was characterized by scanning electron microscopy,X-ray diffraction,Fourier infrared spectroscopy and differential scanning calorimetry analysis. The results show that Zeta potential of silk fibroin rises from-3. 58 m V to 5. 41 m V,and the modified wool fiber scale layer is coated by a silk fibroin film. The wool fiber possesses more hydrogen bonds and amide bonds,and the crystal structure of wool fiber is more stable. The heat-resistant decomposition performance of the cationized silk fibroin treated wool fibers is improved,but the mechanical properties are decreased.However,no significant difference exists in wool fiber structure with different silk fibroin solution modification. Wool fibers have a reduced dye uptake ratio for acid dyes.
