Abstract

Antibacterial and deodorizing garments are essential for ensuring human health. However, achieving durable antibacterial and deodorizing properties in polyester (PET) fabrics remains a significant challenge, as such treatments often compromise moisture permeability and must withstand repeated washing cycles. In this study, these challenges were well addressed through the synthesis of a multifunctional agent, PHMG-β-CD/TP, a host-guest inclusion complex with β-cyclodextrin (β-CD) as the host and tea polyphenols (TP) as the guest. By grafting 5 % o.w.f. of PHMG-β-CD/TP onto PET fabrics, the resulting functional fabrics, PET-5 %, demonstrated outstanding antibacterial rates of 99.99 % against E. coli and S. aureus after 30 washing cycles and a deodorization rate of 99.69 %. Moreover, compared to untreated PET fabrics, PET-5 % retained its moisture permeability and breaking strength while exhibiting significantly enhanced hydrophilicity. This study provides an effective strategy for developing multifunctional antibacterial and deodorizing PET fabrics, paving the way for applications in high-performance garments and other textile products.

抗菌和除臭聚酯织物，增强亲水性，透湿性，拉伸强度和洗涤耐久性

抗菌和除臭服装对确保人体健康至关重要。然而，在聚酯（PET）织物中实现持久的抗菌和除臭性能仍然是一个重大挑战，因为这种处理通常会损害透湿性，并且必须承受反复洗涤循环。在本研究中，通过合成一种多功能试剂PHMG-β-CD/TP，以β-环糊精（β-CD）为宿主，茶多酚（TP）为客体的主客体包合物，很好地解决了这些挑战。将PHMG-β-CD/TP接枝至PET织物上，得到的PET-5%功能织物经30次洗涤后，对大肠杆菌和金黄色葡萄球菌的抑菌率为99.99%，除臭率为99.69%。此外，与未经处理的PET织物相比，PET-5%在保持其透湿性和断裂强度的同时，亲水性显著增强。该研究为开发多功能抗菌除臭PET织物提供了有效的策略，为高性能服装和其他纺织产品的应用铺平了道路。
