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

Abstract

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

Novel Schiff base transition metal complexes for imparting UV protecting and antibacterial cellulose fabric: Experimental and computational investigations

“…[11] More recently, piperazinyl Schiff base has been used to treat CF for potent antibacterial effects. [30] In this study, a cellulose-based azomethine ligand was prepared. Its Fe (III), Mn (II), and Cr (III) complexes were developed as UV protective, and antimicrobial textile fabric will be investigated.…”

Nonleaching Antimicrobial Cotton Fabrics Finished with Hyperbranched Polylysine

“…In this work, a novel nonleaching antimicrobial CF, named HPL-CF, has been prepared by grafting antimicrobial HPL onto the CF with an effective and widely used silane coupling strategy (Scheme 1). 38,39 HPLs are covalently attached to the CF surface without altering the morphology and integrity of the CF. HPL-CFs exhibit excellent antimicrobial activities against E. coli, S. aureus, and C. albicans and maintain a >98% antimicrobial ratio after 50 washing cycles, demonstrating excellent washing durability.…”
