利用MG-6600型拒水拒油剂以及柠檬酸抗皱剂,以轧烘焙、电子束辐照接枝、等离子体预处理-电子束辐照接枝三种工艺对棉织物进行后整理.傅里叶红外光谱(FTIR)证明拒水拒油剂与柠檬酸已成功接枝于棉纤维上;扫描电子显微镜(SEM)分析表明经三种工艺整理后的棉织物表面均有一层覆盖物,且经等离子预处理后的织物表面出现纵向条纹.通过测量棉织物折皱回复角(WRA)、对水的接触角(WCA)、对油(正十六烷)的接触角(OCA)大小来表征织物性能的变化.结果表明,在等离子体预处理-电子束辐照接枝工艺条件下,棉织物的抗皱、拒水、拒油性能达到最优,其WRA为185.9°,WCA为158.9°,OCA为129.1°,断裂强力、白度值均能满足服用要求,同时棉织物的耐水洗性能大大提高.%MG-6600 and citric acid were used as a water and oil repellent and as an anti-wrinkle agent, respectively. Cotton fabrics were subjected to one of the following three processes: (1) the pad-dry-cure process, (2) electron beam irradiation grafting, and (3) plasma pretreatment, followed by electron beam irradiation grafting. Fourier transform infrared spectroscopy (FTIR) proved that MG-6600 and citric acid were successfully grafted onto the cotton fiber. Scanning electron microscopy showed that the surfaces of the three types of treated cotton fabrics were covered by layers. Further, longitudinal stripes appeared on the surface of the fabric subjected to plasma pre-treatment. The change in the cotton fabric properties was characterized by measuring the wrinkle recovery angle (WRA), the contact angle (WCA), and the contact angle to oil (n-hexadecane) (OCA). The results showed that the wrinkle resistance and the water and oil repellency were optimized when the fabric was subjected to plasma pretreatment and electron beam irradiation: the WRA, WCA, and OCA were 185.9°, 158.9°, and 129.1°. Further, the breaking strength and whiteness of the cotton fabric met the requirements of the apparel standards, and the washing durability of cotton fabric was significantly enhanced.
