摘　　要：为提高棉织物的力学性能和热稳定性,采用互穿聚合物网络(IPN)技术,制备了聚N-异丙基丙烯酰胺/丝胶IPN水凝胶;并以戊二醛(GA)为交联剂,通过浸渍法将IPN水凝胶用于棉织物的改性整理。采用傅里叶变换红外光谱仪、扫描电子显微镜、差示扫描量热仪、X射线衍射仪、热失重分析仪和万能材料拉力机对改性棉织物进行测试和表征。结果表明:IPN水凝胶的最低临界溶液温度为30. 79℃;改性棉织物表面和纤维之间形成一层改性凝胶膜,但其结晶2θ角没有偏移;改性棉织物的断裂强度、断裂伸长率和弹性模量分别提高了29. 39%、35. 24%和17. 58%,分解温度提高了61. 79%。In order to improve the mechanical properties and the thermostability of cotton fabrics,the N-isopropyl acrylamide/silk sericin IPN hydrogel was prepared by the interpenetrating polymer network( IPN) technology. The glutaraldehyde( GA) was used as crosslinking agent,and the IPN hydrogel was adopted to modify the cotton fabrics by the impregnation method. The IPN hydrogel and modified cotton fabrics were characterized by Fourier transform infrared spectroscopy,scanning electron microscopy,differential scanning calorimetry,X-ray diffraction,thermogravimetric analysis and universal material tension machine. The results show that the lowest critical solution temperature is 30. 79 ℃ for the hydrogel. A layer of modified hydrogen film is formed between the surface of modified cotton fabrics and the fibers,which crystal 2θ angle has no shift. The breaking strength,elongation at break and elasticity modulus are improved by 29. 39%,35. 24% and 17. 58%,respectively. The decomposition temperature of modified cotton fabrics is raised by 61. 79%.
