Bactericidal Effect of Cotton Fabric Treated with Polymer Solution Containing Silver Nanoparticles of Different Sizes and Shapes

Abstract

Stable silver nanoparticles in solutions of sodium-carboxymethylcellulose (Na-CMC) were synthesized and their structure and physico-chemical properties were evaluated. The form and sizes of silver nanoparticles formed in solutions of CMC and cotton fabrics were studied using UV-VIS spectroscopy, atomic force microscopy and transmission electron microscopy methods. It was found that silver nitrate concentration increase in sodium carboxymethylcellulose solutions, as well as photoirradiation of the hydrogel lead to the changes of the silver nanoparticles size and shape. Investigations have also shown that spherical silver nanoparticles with sizes of 5-35 nm and content of 0.0086 mass% in cotton fabrics possess high bactericidal activity. Stabilization of silver nanoparticles has preserved bactericidal and bacteriostatic activities during the washing of cotton fabrics and textiles on their base.

Advancements in Enhancing Antibacterial Properties of Cotton Fabric through Chitosan and Nanoparticles

“…utilized pure sodium‐carboxymethylcellulose (Na−CMC) with a degree of substitution (DS)=0.65–0.85 and degree of polymerization (DP)=200–400 as polymer matrices along with cellulosic fibers and cotton textiles to get desired fabric. An aqueous silver nitrate solution was used to form AgNPs in Na‐CMC solutions [16] . For synthesizing AgNPs, Dawoud et al.…”

“…One of the most extensively used antibacterial agents is nano‐silver (n‐Ag), due to its large surface area and bacterial growth inhibition quality [14–16] . Chen et al.…”

Polysaccharides and Metal Nanoparticles for Functional Textiles: A Review

“…Yunusov and colleagues reported the stabilizing and reducing properties of a cellulose derivative, carboxymethylcellulose (CMC) [ 134 ]. Carboxymethyl groups attached to the hydroxyl groups of glucose confer hydrophilic properties to this biopolymer [ 135 ].…”

“…Green synthesis, through precursors of biological origin, such as polysaccharides, prevents pollution and mitigates cytotoxicity during the early stages of chemical processes [ 168 ]. Successful synthesis and stabilization of MNPs using these biological macromolecules was achieved in several works by the coordination bonds between the metal salts and functional groups of polysaccharides [ 46 , 72 , 86 , 88 , 105 , 115 , 134 ]. Poor MNP adhesion in textiles is an important challenge for the textile industry, as it results in excessive leaching during washing and disposal, which should be considered prior to their application [ 169 ].…”

“…It is noteworthy that various naturally occurring biologically active substances can be transferred to the microorganism on the surface of nanoparticles. The effect of silver nanoparticles is directly related to their size and shape: the smaller the particle size (optimal 1-10 nm) and the higher their concentration, the more significant the anti-microbial effect; triangular particles are more effective compared to the rod-like and spherical ones (Ahmad et al 2020;Da Silva et al 2020;Talapko et al 2020;Yunusov et al 2020;Enas et al 2021).…”
