Healthcare workers in the hospital environment are at risk of infection and body fluids such as saliva, bacterial contamination, oral bacteria, etc. directly or indirectly exacerbate this issue. These bio-contaminants, when adhered to hospital linens and clothing, grow substantially, as conventional textile products provide a favorable medium for bacterial and viral growth, adding to the risk of transmitting infectious diseases in the hospital environment. Textiles with durable antimicrobial properties prevent microbial colonization on their surfaces and help contain the spread of pathogens. This longitudinal study aimed to investigate the antimicrobial performance of PHMB-treated healthcare uniforms during prolonged usage and repetitive laundry cycles in a hospital environment. The PHMB-treated healthcare uniforms displayed non-specific antimicrobial properties and remained efficient (>99% against and ) after use for 5 months. With the fact that no antimicrobial resistance was reported towards PHMB, the presented PHMB-treated uniform may reduce infection in hospital settings by minimizing the acquisition, retention, and transmission of infectious diseases on textile products.
医院环境中的医护人员面临感染风险，唾液、细菌污染、口腔细菌等体液会直接或间接加剧这一问题。这些生物污染物附着在医院床单和衣物上时会大量滋生，因为传统纺织产品为细菌和病毒的生长提供了有利介质，增加了医院环境中传染病传播的风险。具有持久抗菌性能的纺织品可防止微生物在其表面定植，并有助于遏制病原体的传播。这项纵向研究旨在调查在医院环境中长期使用和重复洗涤周期下，聚六亚甲基双胍（PHMB）处理的医护制服的抗菌性能。经PHMB处理的医护制服表现出非特异性抗菌性能，在使用5个月后仍保持高效（对[具体细菌1]和[具体细菌2]的抗菌率>99%）。鉴于未报告对PHMB产生抗菌耐药性，所展示的经PHMB处理的制服可能通过最大限度减少纺织产品上传染病的获取、留存和传播来降低医院环境中的感染率。
