“…Wang et al loaded nano-silver particles on the surface of cotton ber by covering the surface of cotton ber with polydopamine/polyethyleneimine coating, and the washing resistance and the slow-release property of AgNPs on the ber were greatly improved (Liu et al 2020). Zhou et al grafted CMC and methacrylate onto the cotton fabric to load a coating on the surface of the cotton fabric, then used the coating to x the AgNPs onto the surface of the cotton fabric, The stability of AgNPs on the surface of cotton fabric was improved (Zhou et al 2019). Alternatively, crosslinkable polymers or crosslinking agents have been used to strengthen the binding force between AgNPs and cotton ber.…”

Silver nanoparticles (AgNPs) loaded on the cotton ber can endow the ber with good antibacterial activity, but the AgNPs on the surface of cotton ber will leach out with the increase of washing times, which will not only greatly reduce the antibacterial properties of cotton ber, but also cause pollution to the environment. In this paper, carboxyl groups were introduced into cotton ber by three methods, namely selective oxidation, butane tetracarboxylic acid (BTCA) grafting and polyacrylic acid (PAA) adsorption. The silver ions (Ag + ) were adsorbed on the cotton bers through electrostatic attraction, and after reduction, the AgNPs were loaded onto the cotton bers, and the AgNPs distribution on the ber and its effect to the washing resistance of AgNPs were studied. The results showed that the selective oxidation and the BTCA grafting can introduce carboxylic groups into the interior of cotton bers while the PAA adsorption only imports carboxyl groups on the surface of the ber. As a consequence, AgNPs were formed inside of the cotton ber when the selective oxidation and the BTCA grafting were employed, while AgNPs can only be loaded on the surface of the ber by the PAA adsorption method. AgNPs inside of the ber have high energetic adherence, resulting in silver-cotton fabric nanocomposites with strong slow-release property and long-term antibacterial ability. The fabric nanocomposites prepared by selective oxidation and BTCA grafting exhibited high AgNPs retention rate and excellent antibacterial activity even after 80 washing cycles.

“…38 L-Methionine (MET) improves the durability of antibacterial cotton fabrics. 39 The main reason for the antibacterial effect of hydrophobic amino acids is probably the specific structure of the amino acids. For example, this Pro residue in α-helical generates a kink in the peptide backbone, due to the absence of an amide proton, providing a hydrogen bond donor, and it is usually found within amphoteric α-helical peptides.…”

Walnut (Juglans regia L.) cake meal constitutes a significant amount of solid byproduct from the production of walnut oil, comprising more than 40% protein. However, it is usually not well utilized. Therefore, an antibacterial peptide was obtained by hydrolyzing walnut oil residue protein with pepsin based on the diameter parameters of the antibacterial zone in this research. The purified antibacterial peptide WRPH-II-6 was obtained by two-part purification (ultrafiltration and reversed-phase liquid chromatography) and possessed higher antibacterial activity against Escherichia coli (MIC = 1.33 mg/mL), Staphylococcus aureus (MIC = 0.33 mg/mL), and Bacillus subtilis (MIC = 0.66 mg/mL). The amino acid sequence of WRPH-II-6 was identified as TGSAVPSPRASATATMEMAAAMGLMPGSPSSVSAVMSPF, where the presence of a large proportion of hydrophobic amino acid residues, such as alanine, proline, and methionine, explained the marked antibacterial activity of WRPH-II-6. The harsh sensitivity experiment demonstrated that WRPH-II-6 retains the stability of antibacterial activity when exposed to broad-spectrum pH values, variable temperatures, and long-lasting UV irradiation. The antibacterial mechanism of the WRPH-II-6 peptide against S. aureus and B. subtilis involves nonmembrane disruption: the contact of anions and cations causes the folding and collapse of the bacterial cell membrane to achieve the inhibitory effect. The antibacterial mechanism against E. coli is membrane disruption, which markedly disrupts the bacterial cell membrane to achieve the bactericidal effect. Significantly, the walnut residual protein hydrolysate is a potent preservative and antibacterial agent.

Excitingly, the antibacterial activity of PIVCSBs/silver/cotton fabric was much higher than that of the PIVCSBs/cotton fabric, which may be related to the additional loading of silver nanoparticles.…”

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.
