Chitosan Natural Polymer Material for Improving Antibacterial Properties of Textiles

Abstract

In recent years, the textile industry has been seeking to develop innovative products. It is a good choice to organically combine materials with superior functional characteristics and commercial textiles to form products with excellent performance. In particular, textiles made of biological functional materials are often beneficial to human health, which is an interesting research direction. As a biopolymer material, chitosan has the advantages of strong availability, low cost, excellent safety, outstanding performance, etc., particularly the antibacterial property, and has broad application prospects in the textile field. This review provides an overview of the latest literature and summarizes recent innovations and state-of-the-art technologies that can add value to textiles. To this end, preparation of chitosan fiber, synthesis of chitosan nanofiber, antibacterial activity of chitosan fiber, antibacterial activity of chitosan nanofiber, etc., will be discussed. Furthermore, the challenges and prospects of chitosan-based materials used in textiles are evaluated. Importantly, this review can not only help researchers understand the development status of antibacterial textiles, but also help researchers discover and solve problems in this field through comparative reading.

Chitin oligosaccharides for the food industry: production and applications

“…Allison [47] used 30% H 2 O 2 to degrade partially deacetylated chitosan at 90 °C and obtained a mixture of CHOS and COS. Moreover, CHOS could also be prepared by the acetylation of COS, in which chitin was dissolved in concentrated hydrochloric acid while heated in boiling water and then acetylated with acetic anhydride [48,49]. Although the preparation of CHOS by the chemical method is relatively easy to operate, the reaction process is difficult to control, and the products were often with uneven MW distribution.…”

Antimicrobial polymeric composites for high-touch surfaces in healthcare applications

“…When the pH is lower than pKa, amines in the chitosan can be protonated so that electrostatic interaction occurs between the positively charged polymer and the negatively-charged bacterial cell wall, whereas chelation and hydrophobic interaction predominate the antimicrobial performance of chitosan when pH is higher than pKa. While chitosan is typically used as an additive for coating textiles to provide antimicrobial activity 39 , it has also been shown to provide antimicrobial activity when incorporated into polymer composites such as poly(methyl methacrylate) 40 . ε-poly-L-lysine (EPL) is an intrinsic cationic lysine homopolymer (n=25-30) with ε-amino and α-carboxyl groups bonded by amides.…”

Fluorescence and electrochemical integrated dual-signal sensor for the detection of iron ions in water based on an ITO substrate

“…S4a, † the maximum fluorescence intensity was obtained at a pH-I of 9.5, indicating that Chi-FITC-4MU had the best synthetic effect, because the chitosan was precipitated in alkaline solution. 38,39 The effect of the buffer solution pH on the formation of Chi-FITC-4MU-Fe 3+ was investigated using acetate buffer with the pH-II range of 2.0-6.0.
