Chitosan hydrogel‐coated cotton fabric: Antibacterial, pH‐responsiveness, and physical properties

Abstract

In this work, chitosan hydrogel has been synthesized and used to impart pH‐sensitivity and antimicrobial finish to cotton fabric. In order to enhance the incorporation rate of hydrogel, anionic, and cationic activation of the textile surface was applied and then compared. The antibacterial activity of the fabric was then studied. The results revealed an enhancement of the antibacterial activities of the modified fabrics against Escherichia coli, Listeria monocytogene, and Staphylococcus aureus bacteria's. The capacity of material to respond to pH change was studied and confirmed using contact angle method. The anionic fabric treated with hydrogel showed a better pH‐responsiveness. Scanning electron microscopic testing results has also confirmed that the deposition of hydrogel was clearly better with the anionic activation. The characteristics of breathability of the fabrics were analyzed. The results show that the moisture management behavior of the finished materials is significantly better than the control one. Although the permeability to air has reduced by 10%, the permeability to water vapor remained practically unchanged. Furthermore, the effects of the antibacterial finishing on the physical properties of the cotton fabrics were also investigated. It was established that the functionalized samples have changed structure parameters, thickness, air permeability, tensile strength, and resistance to wrinkles. © 2018 Wiley Periodicals, Inc. J.

Evaluation of single-component chitosan fiber: from advanced materials to contemporary fashion manufacturing

“…Such an approach has also been adapted in a previous study on the effect of demineralization on degradable chitosan fiber. 9 Other articles involve bio-performances, such as cell growth 10 and emission 11 promotion, acid resistance, 12,13 and chemical extraction. 14,15 Articles involving the anti-microbial performance of chitosan mostly focus on the solution state, and therefore in this study we conducted chitosan anti-microbial performance tests in both its fiber and solution states.…”

Yarn-reinforced hydrogel composite produced from woven fabrics by simultaneous dissolution and cross-linking

“…15 Woven glass fabric–reinforced and high energy-dissipative polyampholyte matrix hydrogel composite as strong structural biomaterial with high toughness and tensile properties were produced by Huang et al 13 Cotton (Co) fabric was treated with as-synthesized chitosan hydrogel for pH sensitivity and antimicrobial properties. 16 The surface of fabric was modified with hydrogel via covalent bonding for wound dressing application that the hydrogel structure was isolated from protein. 17 Konjac glucomannan–based hydrogel was prepared and coated on glass fabrics for oil–water separation in harsh environments.…”

One-step preparation of woven fabric-reinforced hydrogel composite

“…The load-to-failure capacity of neat textiles via hydrogel infiltration and wear resistance of the hydrogel matrix were improved. Recent studies were reported in the literature on hydrogel coated or treated fabric structures, but one-step preparation of fabric-reinforced hydrogel structures from a woven fabric has not been studied [16–18].…”
