Abstract

COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and healthcare-associated infections (HAIs) represent severe problems in health centers and public areas. Polyester/cotton (PES/CO) blend fabrics have been functionalized with copper oxides on an industrial scale. For functionalization, the impregnation dyeing technique was applied. The functionalized samples were tested virologically against SARS-CoV-2 and human coronavirus (229E) according to ISO 18184-2019 and microbiologically against (ATCC 25922) bacteria according to ASTM E2149-2013. The results show that the fabric functionalized with copper oxides inactivated both viruses after 30 min of exposure, presenting excellent virucidal activity against 229E and SARS-CoV-2, respectively. Furthermore, its inactivation efficiency for SARS-CoV-2 was 99.93% and 99.96% in 30 min and 60 min exposure, respectively. The fabric inhibited bacterial growth by more than 99% before and after 10 and 20 washes. In conclusion, 265 m of PES/CO fabric (wide 1.7 m) was functionalized in situ on an industrial scale with copper oxide nanoparticles. The functionalized fabric presented virucidal and bactericidal properties against SARS-CoV-2 and .

摘要

新型冠状病毒肺炎（COVID-19）由严重急性呼吸综合征冠状病毒2（SARS-CoV-2）引起，医疗保健相关感染（HAIs）是医疗中心和公共场所的严重问题。聚酯/棉（PES/CO）混纺织物已在工业规模上用氧化铜进行功能化处理。对于功能化处理，采用了浸染染色技术。根据ISO 18184-2019对功能化样品进行了针对SARS-CoV-2和人冠状病毒（229E）的病毒学测试，并根据ASTM E2149-2013对其进行了针对（ATCC 25922）细菌的微生物学测试。结果表明，用氧化铜功能化的织物在暴露30分钟后使两种病毒均失活，分别对229E和SARS-CoV-2表现出优异的杀病毒活性。此外，其对SARS-CoV-2的灭活效率在暴露30分钟和60分钟时分别为99.93%和99.96%。该织物在洗涤10次和20次前后均能抑制细菌生长超过99%。总之，265米宽1.7米的PES/CO织物在工业规模上用氧化铜纳米颗粒进行了原位功能化处理。功能化织物对SARS-CoV-2和……表现出杀病毒和杀菌性能。 （注：原文中“against (ATCC 25922) bacteria”这里括号前的内容缺失，译文按原文翻译）
