Due to the increase in biological hazards to global security particularly after COVID-19 crises, the need to develop effective and adaptable technologies to protect humans from biological warfare agents (viruses, bacteria, fungi) has increased. Current protective textiles against biohazards are fabricated through finishing of textiles with bioactive agents. However, bioactive agents are leached from the treated textiles due to the poor durability following their accumulation in environment. The objective of this research was to design a sustainable approach for developing ecologically sound antimicrobial textiles in which the antimicrobial agent is covalently bonded to fabric and does not leach into the effluent when laundered. For this, a novel bifunctional reactive finish was synthesized in which chloroxylenol (antimicrobial agent) was covalently integrated into two reactive systems (triazine and vinyl sulfone). For structural validation, 13C NMR, 1H NMR, and, FTIR characterization were employed. The as-synthesized reactive finish was applied on the cotton fabric through pad-dry-cure method. The antimicrobial action of treated fabric (before and after 20 laundry cycles) towards viruses, bacteria, and fungi as well as ultraviolet protection factor (UPF) were evaluated according to standard. The treated fabric showed significant fungicidal (>85 %) bactericidal (>95 %), and viricidal (>85 %) action, that remained effective even after 20 washes, revealing that antimicrobial agent has not leached during washing of treated textiles which established non-leaching behavior of the treated textiles. The treated fabric also exhibited outstanding UPF values (>135). The current study has proposed a novel approach for the fabrication of ecologically sustainable antimicrobial textiles and the proposed method is easily scalable at industrial level.

使用环保的新型纤维活性生物活性剂开发防护棉纺织品以抵御生物危害和有害紫外线辐射

由于对全球安全的生物危害增加,尤其是在 COVID-19 危机之后,开发有效和适应性强的技术来保护人类免受生物战剂(病毒、细菌、真菌)侵害的需求增加了。目前针对生物危害的防护纺织品是通过用生物活性剂整理纺织品制成的. 然而,由于在环境中积累后的耐久性较差,生物活性剂会从处理过的纺织品中浸出。这项研究的目的是设计一种可持续的方法来开发生态无害的抗菌纺织品,其中抗菌剂与织物共价结合,并且在洗涤时不会渗入废水中。为此,合成了一种新型的双功能活性整理剂,其中氯二甲酚(抗菌剂)共价结合到两个活性系统(三嗪和乙烯基砜)中。对于结构验证, 13C NMR,1采用 H NMR 和 FTIR 表征。将合成后的活性整理剂通过浸轧干固化法施涂在棉织物上。根据标准评估处理过的织物(20次洗涤循环前后)对病毒、细菌和真菌的抗菌作用以及紫外线防护系数(UPF)。处理过的织物显示出显着的杀菌 (>85%) 杀菌 (>95%) 和杀病毒 (>85%) 作用,即使在 20 次洗涤后仍然有效,表明在洗涤处理过的纺织品期间抗菌剂没有浸出- 处理过的纺织品的浸出行为。处理过的织物还表现出出色的 UPF 值 (>135)。
