Innovative Multi-Protection Treatments and Free-Salt Dyeing of Cotton and Silk Fabrics

Abstract

In recent years, with the improvement of the living standard, people pay more attention to the health function of textiles that could be a shield or pathogen transmission medium. In the present work, surface cationization of cotton and silk fabrics was demonstrated by increasing the nitrogen content (N %) values. Different treatment techniques were successfully applied using chitosan, UV absorber, and reactive dye for producing multipurpose protective cotton and silk fabrics. Protective properties such as UV-blocking activity achieved a remarkable enhancement in UPF values (50+) and excellent protection. The anti-odor activity as measured by antibacterial reduction percentage was 98% for cotton and 99% for silk fabrics. Significant enhancement in dyeability values of cotton and silk fabrics are demonstrated. The durability of the treated fabrics was assessed after 30 repeated washing cycles and the treatment formulations showed sustainable UV blocking properties and anti-odor efficiency.

“…The fabrics were then thoroughly rinsed with water and finally dried at ambient temperature. The optimum treatment type and conditions were obtained as mentioned in detail in the previously published work [2]. -Simultaneously UV absorber treatment and dyeing: Cotton and silk fabrics were subjected to simultaneously salt-free UV absorber treatment [3% o.w.f.]…”

“…They acquire wide acceptance and appreciation between peoples as apparel products because of their properties such as good moisture absorption, dyeing affinity, thermal tolerance, perspiration management and comfort, good folding, shiny aspect, soft handle, good elegant drape. The next step in the design process is pattern engineering, and finally, the garment assembly allowing them to fulfill the predetermined requirements, comfort, protection and functionality [2,6].…”

“…The function of a UV absorber finishing of textiles is to absorb UV radiation effectively throughout the UV region (280-400 nm). UV absorbers convert the electronic excitation energy into thermal energy through a fast-reversible intramolecular proton transfer reaction [2]. Textiles act as carriers for microorganisms, especially in natural fibers such as cotton and silk because of their hydrophilic nature.…”

“…They prevent unpleasant odor on intimate apparel, underwear, socks, athletic wear, and even daily use outfits. Additionally, the unpleasant odor has a negative impact on textiles and their comfort properties and the aesthetic function [2].…”

“…As the ozone layer was far less protective, more UV light hits the earth. Long-term exposure to Ultraviolet light can progress to a variety of skin disorders, namely skin aging acceleration, photodermatoses (acne) and skin cancer, skin inflammation and corneal scarring [1,2].…”
