The main goal of the present study was the fabrication of wood/polyvinyl chloride (WPVC) composite with enhanced properties. In this regard, the wood fibers were primarily bleached with sodium chlorite and then dyeing of fibers was carried out with green walnut shells as a natural dye. Influences of natural dye on color, antibacterial, and mechanical properties of the composite were investigated. The WPVC composite showed excellent antibacterial activity measured against two common pathogenic bacteria including Escherichia coli and Staphylococcus aureus. Also, negligible toxicity of the composite was proven with cytotoxicity test. Furthermore, the color variation of the bleached sample after light irradiation was negligible, which demonstrated the proper colorfastness of the composite.

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.

“…3−5 Consequently, there is growing interest in hair dyes based on natural molecules owing to their abundance, biocompatibility, low toxicity, and eco-friendliness. 6−8 Various plants, including walnut hull, 9 chamomile, 2 and logwood, 10 have been reported in literature for their potential application as natural hair dye sources. In general, natural colorants have poorer retention ability than synthetic dyes: their degradation by light and color fading after wash may limit their use as well as the low color intensity due to the low adhesion and permeability.…”

Plant-based colorants in hair dyeing are popular due to their lower toxicity for health and the environment compared to conventional chemically synthesized dyes. However, the application of plant colorants in hair dyeing is limited due to their low adsorption and poor fastness. In this study, we aimed to enhance the hair dyeing performance of a plant-based colorant (curcumin) by prelinking thiol groups (referred to as "click dyeing") and investigated the dyeing effect and restorative function. The results demonstrated that click dyeing significantly improved curcumin's coloring ability and color fastness, with the retention ratio of color reaching 80% after seven shampoo washes. Additionally, click dyeing enhanced the mechanical properties of the bleached hair and reduced keratin loss. Fluorescence labeling experiments confirmed that curcumin reacted with the introduced thiol groups through a thiol-Michael click reaction. After click dyeing, the mechanical properties of the hair fibers were repaired due to the formation of chemical bonds during the click reaction, resulting in a 9.81% increase in tensile strength compared to bleached hair before the hair dyeing process. The mechanism behind this enhancement lies in the restoration of the keratin conformation by click dyeing, bringing various properties back to their original state. Furthermore, the study verified curcumin's ability to resist photoaging through xenon arc lamp radiation and electron spin resonance (ESR) spectroscopy.
