Abstract

This study aims to explore the essential functional requirements associated with controlling the proliferation of microbes in the domain of textiles used in public health areas. Herein, three antimicrobial agents, specifically iodopropylbutylcarbamate (IPBC), 1-hydroxypyridine-2-thioketone zinc (ZPT), and 2-octyl-3-isothiazolinone (OIT), were chosen for fabric finishing based on their notable effectiveness, minimal toxicity, cost-efficiency, and chemical stability. Utilizing Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) as representative bacterial strains, the Minimum Inhibitory Concentration (MIC50) of individual and combined antimicrobial agents was measured, and their antimicrobial effectiveness was rigorously evaluated. Concurrently, the antimicrobial effectiveness, whiteness, and mechanical durability of the fabric following antimicrobial treatment were thoroughly examined. The results demonstrate that some combinations of the three antimicrobial agents elicit additive effects on both S. aureus and E. coli. Notably, at an equivalent ratio of IPBC, ZPT, and OIT and a total concentration of 0.2 wt. %, the inhibition rates against both bacterial strains surpass 99%. Upon application to nylon fabric, the treated material demonstrates significant antimicrobial properties, with minimal reduction observed in the whiteness and tensile strength of the treated nylon. This study provides practicable strategies relevant to the production of textiles endowed with antimicrobial properties.

通过复合抗菌剂提高纺织品的杀菌性能。
本研究旨在探讨在公共卫生领域使用的纺织品中,与控制微生物增殖相关的基本功能要求。在此,我们选择了三种抗菌剂,特别是氨基甲酸碘丙基丁酯(IPBC)、1-羟基吡啶-2-硫酮锌(ZPT)和 2-辛基-3-异噻唑啉酮(OIT),这些抗菌剂具有显著的功效、最小的毒性、成本效益和化学稳定性,可用于织物整理。以金黄色葡萄球菌(S. aureus)和大肠杆菌(E. coli)为代表菌株,测定了单独抗菌剂和组合抗菌剂的最低抑菌浓度(MIC50),并对其抗菌效果进行了严格评估。同时,还对抗菌处理后织物的抗菌效果、白度和机械耐久性进行了全面检测。结果表明,三种抗菌剂的某些组合对金黄色葡萄球菌和大肠杆菌都有增效作用。值得注意的是,当 IPBC、ZPT 和 OIT 的比例相等且总浓度为 0.2 wt. % 时,对这两种细菌菌株的抑制率都超过了 99%。在应用于尼龙织物时,经处理的材料显示出显著的抗菌特性,而且经处理的尼龙的白度和拉伸强度的降低幅度极小。这项研究为生产具有抗菌特性的纺织品提供了切实可行的策略。

期刊介绍: Biointerphases emphasizes quantitative characterization of biomaterials and biological interfaces. As an interdisciplinary journal, a strong foundation of chemistry, physics, biology, engineering, theory, and/or modelling is incorporated into originated articles, reviews, and opinionated essays. In addition to regular submissions, the journal regularly features In Focus sections, targeted on specific topics and edited by experts in the field. Biointerphases is an international journal with excellence in scientific peer-review. Biointerphases is indexed in PubMed and the Science Citation Index (Clarivate Analytics). Accepted papers appear online immediately after proof processing and are uploaded to key citation sources daily. The journal is based on a mixed subscription and open-access model: Typically, authors can publish without any page charges but if the authors wish to publish open access, they can do so for a modest fee. Topics include: bio-surface modification nano-bio interface protein-surface interactions cell-surface interactions in vivo and in vitro systems biofilms / biofouling biosensors / biodiagnostics bio on a chip coatings interface spectroscopy biotribology / biorheology molecular recognition ambient diagnostic methods interface modelling adhesion phenomena.
