Highly Antibacterial Efficacy of a Cotton Fabric Treated with Piperazinyl Schiff Base

Due to the structure of hierarchical aligned cellulose fibrils, cotton fabric used in clothing possesses excellent moisture and thermal managements. Such yet may retain metabolic excrements sebum secretions discharged from human skin, which reproduce microorganisms harmful for health. However, incorporating antimicrobial coating into can sufficiently resist microorganism growth. In this work, a water-soluble antibacterial named N-(4-(allyloxy) benzylidene)-2-(piperazin-1-yl) ethanamine (NABPE) was synthesized produce rechargeable fast sterilization fiber (M-cotton/NABPE). M-cotton/NABPE exhibited high effective activity, inhibition ratios against Escherichia coli (E. coli) Staphylococcus aureus (S. aureus) were 94 % 93 %, respectively. Chlorination performed with sodium hypochlorite solution form N-Cl bond on fabrics, resulting biocidal efficacy up 100 via contact killing duration 5 min. After 25 washing cycles, still maintained an rate 91.95 92.15 E. S. aureus, Furthermore, fabrics showed integrated properties UV stability, long-term robust activity (chlorine recharging >5000 ppm) durability. This research provides fundamental insights synthesis NABPE prolonged M-cotton/NABPE, thereby pave pathway incorporate economic environmental-friendly suitable finishing fabric.
