“…The hydroxyl groups of cellulose chains on the cotton surface form coordination bonds with the AgNPs, but the quantity of the coordination bonds is limited by the three-dimensional shapes of the cotton fiber and AgNPs. As reported in a number of papers [38,[41][42][43][44][45][46] using the binder of the modified chitosan, both the quantity (chitosan chains wrapping on the Ag NP surface) and the bond strength (amino groups are stronger than hydroxyl groups) of the coordination bonds with Ag NP increased, resulting in a stronger adsorption of the AgNPs on the cotton surface. Figure 9 shows the TGA data of the original cotton, the modified cotton fabrics before and after 30 laundering cycles.…”

“…The modified fabrics exhibited durable antimicrobial effect after 10 washing cycles (BR > 99 %). Li et al [41] reported a novel graft polymerization method using 2-aminoethyl methacrylate as the monomer. Because the primary amine groups in the monomer form coordination bonds with the Ag ions, the resulting polymer tightly wraps the AgNPs, and simultaneously adheres to the fiber surface via the hydrogen bonds between the ester and the hydroxyl groups.…”

This article focuses on the functional finishing of textiles using silver nanoparticles (AgNPs) and chitosan derivative binder, which was synthesized by a modification of chitosan using α-ketoglutaric acid. The binder covalently linked to cotton fabric via esterification of the hydroxyl groups on the cotton surface, and tightly adhered to surface of the AgNPs by coordination bonds. As a result, the coating of AgNPs on the cotton fabric showed excellent antibacterial property and laundering durability. After 30 consecutive laundering cycles, the Ag content on the fabrics decreased to 37.6 %, but the bacterial reduction rates against both S. aureus and E. coli were maintained over 95 %. It has potential applications in a wide variety of fields such as sportswear, socks, and medical textile.

There is growing interest in the area of conductive textiles in the scientific and industrial community. Herein, we successfully prepared a conductive textile via covalently grafting polyaniline (PANI) onto cotton by a multi-step treatment process. The conductivity of the resultant fabric could be tuned by immersing in water having different pH values. The conductive and insulating properties of the textile could be conveniently switched by alternately immersing in acidic and alkaline bath solutions. Most importantly, the resultant conductive fabrics were able to withstand 40 simulated dry-wash cycles, with almost no decay in the electrical conductivity, indicating their excellent dry-wash durability. The present strategy for fabricating conductive fabrics with excellent switchability of electrical properties and dry-wash durability is expected to provide inspiration for the production of multifunctional conductive textiles for use in hash or sensitive conditions.

“…It is also potential that the attachment of AgNPs onto fabrics is by AgNPs‐amino groups interaction. An observation was carried out for cotton fibers incorporated with AgNPs . X‐ray photoelectron spectroscopy investigation confirmed that there was the coordination force of the amino group in the monomer with AgNPs.…”

This article provides a comprehensive understanding of development of textiles functionalized with silver nanoparticles (AgNPs). There are three established methods to fabricate textiles functionalized with AgNPs, namely, solution‐immersion, layer‐by‐layer deposition, and sonochemical. In addition, several textile types such as cotton, wool, polyester, silk, cotton/polyester blend, polyamide, and regenerated cellulose have been used for the fabrication. The AgNP deposition mechanism on textiles is mainly due to electrostatic interaction between AgNPs and textile constituents. It was exhibited that the deposition of AgNPs on textiles can transform their textiles colors. In addition, it was demonstrated that the deposition of AgNPs on textiles is not permanent, particularly against washing treatment. Textiles modified with AgNPs have several promising applications such as antibacterial, antifungal, catalyst, electronic devices, water treatment, sun protection, air treatment, and surface‐enhanced Raman scattering, which are comprehensively discussed in this article. Future challenges in fabricating textiles functionalized with AgNPs remain on how this can be carried out to improve long‐term stabilization of AgNPs on textiles to achieve their permanent deposition by employing greener approaches.
