电子辐射技术抗菌整理棉织物研究

Antibacterial finishing of cotton fabrics by electron beam irradiation

选用卤胺抗菌剂甲基丙烯酰胺(MAM)为单体,采用预辐射、共辐射工艺制备抗菌棉织物。研究了辐射量对织物含氯量和断裂强力的影响。同时,将辐射工艺与轧烘焙工艺所制备的抗菌棉织物做比较。织物经红外光谱和扫描电镜表征,断裂强力及抗菌性测试。结果表明:3种工艺所制备抗菌棉织物在红外光谱和扫描电镜表征中无明显差别。但经共辐射工艺所制备的抗菌棉织物断裂强力较好、且杀菌效果明显。

Pre-irradiation process and co-irradiation process was employed in antibacterial finishing of cotton fabrics with N-halamine antiseptics methacrylamide（MAM）as monomer.The effects of irradiation dose on chlorine content and breaking strength of cotton fibers were studied.Meanwhile,the electron beam irradiation was compared with dip-pad-cure procedure.The treated cotton fabrics characterized by FT-IR spectra and SEM,and examined by breaking strength and antibacterial test.The results showed that the FT-IR spectra and SEM of the grafted cotton fibers via three methods had no obvious difference.However,the treated cotton fabrics via co-irradiation process performed better in breaking strength,and obtained good antibacterial property.
