涤服非织造布的制备及抗菌性能研究

Study on the preparation and antibacterial properties of polyester or silver nonwoven fabrics

银系抗菌材料因其持久、高效的抗菌效果被广泛应用于医疗卫生、宋纺、服饰等领域，但银离子易被还原、对光和热比较敏感，耐气候性并不强。中空载银纤维较大程度避免了银离子与外界环境的接触，有效延长材料的抗菌性能。以中空载银纤维和涤纶纤维为原料，通过水剌法制备涤／银抗菌非织造布。对不同配比的涤／银抗菌非织造布的表面形态、柔软性、透气性及抗菌性能进行测试与研究。结果表明：随着载银纤维含量的增加，涤／银非织造布的柔软性和透气性降低，抗菌性增强。当载银纤维含量为5％时．抑菌率已达到76%。

In this paper, a novel spun-laced nonwoven fabric was prepared by using PET fiber with hollow fiber containing silver particles （HF-Ag）, The properties of softness, air perme- ability and antibacterial were analyzed. The results showed that the PET/HF-Ag spun-laced non- woven had a good biomedical performance, and with the increase of the content of HF-Ag fiber, its antibacterial increased while softness and air permeability decreased. When the concentration of HF-Ag was 5%, the inhibitory ratio reached up to76%.
