One of the directions of development in the textiles industry is the search for new technologies for producing modern multifunctional products. New solutions are sought to obtain materials that will protect humans against the harmful effects of the environment, including such factors as the activity of microorganisms and UV radiation. Products made of natural cellulose fibers are often used. In the case of this type of material, it is very important to perform appropriate pretreatment before subsequent technological processes. This treatment has the aim of removing impurities from the surface of the fibers, which results in the improvement of sorption properties and adhesion, leading directly to the better penetration of dyes and chemical modifiers into the structure of the materials. In this work, linen fabrics were subjected to a new, innovative treatment being a combination of bio-pretreatment using laccase from Cerrena unicolor and modification with CuO-SiO2 hybrid oxide microparticles by a dip-coating method. To compare the effect of alkaline or enzymatic pretreatment on the microstructure of the linen woven fabrics, SEM analysis was performed. The new textile products obtained after this combined process exhibit very good antimicrobial activity against Candida albicans, significant antibacterial activity against the Gram-negative Escherichia coli and the Gram-positive Staphylococcus aureus, as well as very good UV protection properties (ultraviolet protection factor (UPF) > 40). These innovative materials can be used especially for clothing or outdoor textiles for which resistance to microorganisms is required, as well as to protect people who are exposed to long-term, harmful effects of UV radiation.

“…Studies into the light stabilization of knitted materials, reported in papers [14,15], are aimed at improving the promtective properties of knitted materials against UV radiation relative to human skin. Based on the use of metal oxide nanoparticles, the authors of work [14] developed knitted fabrics with a high degree of protection against UV radiation and antibacterial properties.…”

Analysis of modern production indicators of textile products by types in the world shows that knitwear manufacture volume exceeds that of woven fabrics [3-5]. This is due to the fact that knitwear, owing to the knitted structure, is characterized by elasticity, thermal conductivity, by the capability to drape, and is indispensable in the manufacture of hosiery, underwear, sportswear. However, it should be noted TECHNOLOGY ORGANIC AND INORGANIC SUBSTANCES

“…14 Overexposure to solar-UVR (i.e., ∼5% of terrestrial solar radiation) can cause sunburn, skin aging, and increase skin cancer risk. 15 Increasingly active human lifestyles, including outdoor activities, raise the probability and risk of exposure, especially in the face of changing climates. 16,17 While suncreams are established for sun protection, they are often insufficiently, irregularly, and improperly applied.…”

We report on the in situ silver-seeded generation and growth of pure wurtzite zinc oxide (ZnO) onto woven cotton fabric substrates via sonochemical deposition. Coating leaching issues and limitations related to processing temperature often restrict the direct application of crystalline metal oxides onto soft matter substrates under ambient conditions. Herein, we describe a mechanochemical synthesis route that allows for the direct generation and durable incorporation of crystalline metal and metal oxide materials onto polymeric substrates, at high loading, without the use of binders, annealing steps, low-vacuum processing, or any other conventionally encountered processing procedures. The model system of Ag-seeded, ZnO on woven cotton textile fabrics presented here demonstrates this efficacy while further doping of the system with Fe allows for the ZnO coating optical properties to be readily tuned. Samples were characterized with X-ray diffraction, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, UV−vis transmittance-reflectance spectroscopy, inductively coupled plasma optical emission spectroscopy, as well as air permeability and tensile testing. While the results for this model system show excellent crystallinity, attachment durability/washfastness, and tunable optical parameters, this synthesis method also offers broader routes to the ready incorporation of textured crystalline metal, metal oxide, and other systems into low-temperature stable, soft matter substrates. For the illustrative application of UV-blocking capability, the coated substrates output consistently high UV-protection factor values (>UPF50), even after 51 wash laundering cycles, and with near-complete suppression of UV-A and UV-B radiation.
