摘　　要：选用(3-丙烯酰胺丙基)三甲基氯化铵(APTAC)为抗菌单体,采用真空等离子体工艺制备抗菌牛仔织物。根据不同溅射气体、流量、功率等条件下织物甲基橙吸附静电荷程度,正交试验策略优化最佳整理工艺,并采用X射线能谱分析、扫描电子显微镜、傅里叶变换红外光谱仪对整理后的纯棉牛仔织物进行表征,测试分析了整理前后织物的强力、手感风格、透气性及抗菌性能。结果表明:在溅射气体为Ar/O2混合且溅射流量比例为50:50、功率为500 W、处理时间为5 min条件下,APTAC成功接枝到牛仔织物上,且不会影响其透气性和力学性能。抗菌测试表明:改性后牛仔织物在30 min的接触时间内,对金黄色葡萄球菌(S.aureus)的灭活率为92.8%,对大肠杆菌O157:H7(E.coli O157:H7)的灭活率为94.87%,具备较好的抗菌性能。The antimicrobial agent 3-(acrylamidopropyl)trimethylammonium chloride(APTAC)was grafted onto vacuum plasma‒treated denim fabrics.Optimal treatment conditions,including sputter-gas species,gas pressure,power,and duration were investigated using Orthogonal Array Testing Strategy(OATS)analysis.The obtained denim fabrics were characterized using energy dispersive X-ray(EDS),Fourier transform infrared spectroscopy(FTIR),and scanning electron microscopy(SEM).Strength,tactile quality,air permeability,and antibacterial properties of the denim fabric before and after grafting were characterized.The results showed that APTAC was successfully grafted onto the denim fabric under conditions using an argon/oxygen mixture as sputtering gas,a sputtering flow ratio of 50:50,a vacuum plasma discharge power of 500 W,and a treatment time of 5 min without affecting the fabric’s air permeability or mechanical properties.Antibacterial efficacy tests showed that APTAC-treated cotton fabric inactivated 92.8% of S.aureus and 94.87% of E.coli O157:H7 in 30 min contact time,thereby achieving sound antimicrobial activity.
