“…A few studies published recently found that the use of organic UV absorbers like o-hydroxyphenyl hydrazines, o-hydroxyphenyl benzotriazole, o-hydroxyl benzophenones and o-hydroxyphenyl triazines, as well as nanomaterials of titanium dioxide, silicon dioxide and zinc oxide, improved the UV-protective property of textiles, with an enhanced UPF compared with that of untreated fabrics. [195][196][197] However, the potential effects of these synthetic substances on the environment and human health are a major concern that may restrict their widespread use. [198][199][200][201][202][203] To reduce the use of hazardous agents, scientists around the world have been working on fabricating UVprotective textiles using plant-based dyes.…”

The current study provides the first review of alizarin, a natural dye, in terms of its historical aspects and its potential for functional applications in textiles. The review begins with a brief overview of natural alizarin and its occurrence in Rubiaceae family plants, followed by a discussion of alizarin acquisition from its botanical sources through conventional and advanced extraction methods. A special emphasis of this study is on the identification of natural alizarin colourants in archaeological and cultural textiles by using analytical methods based on reflectance, Raman spectroscopy, mass spectrometry and chromatographic profiles. In addition, the functional properties of natural alizarin, including its antimicrobial activity, anti‐oxidant activity, insect repellence and ultraviolet protection, are analysed. This paper summarises the methods for obtaining alizarin for coloration, as well as advanced techniques for detecting alizarin in historical textiles, and potential applications of natural alizarin as a functional textile dye.

“…Higher UPF values correspond to higher protection levels with more effective UV radiation (UVB and UVC) blocking ability. AS/NZS 4399:1996 Sun Protection Evaluation classifies different UPF values as bad (< 15), good (14-24), very good (25-39), and excellent (> 40) [41,42]. The UV protection ability of the undyed wool (native pristine wool) was found to be poor with a UPF value of 12.25.…”

“…Among the different metal mordants, Fe/Cu combination provided the best results of the highest protection levels with a UPF value of 60.61. The UV protection performance of natural dye extracts is due to the energy dissipation of the absorbed UV radiations throughout the conjugated structures of dye chromophores [42].…”

This work presents the valorization of Millettia laurentii carpentry sawdust waste into sustainable natural dye for ecological dyeing and functional finishing of wool textiles. A simple aqueous extraction method was used to isolate natural dye, then the extracted bio-dye was subjected to different qualitative and quantitative analyses. Wool yarns were dyed in conjunction with different metal salts (aluminum sulfate, ferrous sulfate, copper sulfate, and zinc sulfate) and their binary combinations (Al/Fe, Al/Cu, Al/Zn, Fe/Cu, Fe/Zn, and Cu/Zn) as mordants. Practically, 11 different eco-friendly shades were developed of varying hues and tones employing 75% (o.w.f.) of M. laurentii sawdust. The antibacterial action against E. coli and S. aureus, free radical scavenging power, and UV protection properties of dyed wool yarns were recorded. The introduction of different metal salts and their combinations enhanced the color properties with a semi-durable antimicrobial and antioxidant finish. Statistical analysis of the color parameters of binary mixed metal combinations confirms the synergetic contribution of individual metal ions in each combination. The amount of individual mordant adsorbed (weight percentage) from a particular combination was further assessed by EDX analysis of mordanted dyed wool yarns. Overall, the results suggest that copper sulfate and ferrous sulfate pre-treatment were the best combinations (Fe/Cu) for wool yarns in conjunction with 75.0% (o.w.f.) M. laurentii sawdust, considering the color fastness, antimicrobial, and antioxidant properties. The results provide ample scope for the upcycling of timber industry waste into a natural dye for the eco-friendly coloration of wool textiles.

“…The demand for protective clothing in the global market has increased in the past few years because of the increasing awareness among consumers about the destruction caused by microbes, UV radiation, dust, chemicals, moths, fire, and other hazardous substances. Hence, specialty garments and furnishings are expected to have desired qualities like water and oil resistance, fire retardancy, self-cleaning, insect and moth repellent, UV protection, and microbial resistance. , Nanoparticles of metal and metal oxides such as Ag, ZnO, Al 2 O 3 , TiO 2 , SiO 2 , and Cu are known agents for imparting various functional finishes to the textiles as summarized in Table .…”

Today, consumers are well aware of the functional protection properties of textiles, in addition to their aesthetic appearance. The use of nanoparticles for specialty finishing is an emerging area in textile processing and engineering. With the advancement in technology, it is possible to fabricate nanoparticles of the desired size and shape with various functional properties. Reports are available on the use of nanoparticles for antimicrobial, UV protection, flame retardant, and hydrophilic and hydrophobic finishes on textiles. Pathogens are a potential threat to humans and also gaining resistance to conventional antimicrobial agents. Thus, it is needed to find new and sustainable antimicrobial formulations. Metal nanoparticles have the potential ability to penetrate and destroy the cell membrane structure and eventually cause cell death. The nano-finished textiles could find various medical and hygienic applications. This review discusses recent research attempts to impart antimicrobial finishes to textiles using metal nanoparticles, focusing on the action of microbes on textiles, the synthesis and application of nanoparticles, their antimicrobial properties, the mechanism of action, toxicity studies, and important applications.
