Sodium lignosulfonate (NLS), a biomass waste procured from paper and pulp industries as brown colour water soluble powder, is explored in this article as dye for nylon 6 fabrics in aqueous media by the exhaustion method. The fastness and functional properties of the dyed nylon 6 fabrics were studied. The dyeing process parameters were optimised using Box–Behnken response surface design and the ANOVA technique. The NLS treated dyed nylon fabric exhibited an excellent ultraviolet protection factor (UPF), as high as 62.13. The NLS dyed nylon fabrics were characterised using FTIR, FESEM, EDX and instruments. The ultraviolet protection factor (UPF) and colour strength (K/S) values are significantly increased with an increase in the concentration of NLS without any loss of tensile properties and thermal stability. Moreover, NLS treatment has excellent wash fastness. This dyeing process for synthetic fibre like nylon can be a cleaner and more eco-friendly approach by utilising waste biomass of paper from the pulp industries.

The effect of sodium lignosulfonate (LS) treatment on nylon fabric for enhancing its ultraviolet protection ability has been studied. Various concentrations of LS were applied on nylon fabric using the exhaust method and the treatment was optimized using Box–Behnken response surface design. The ultraviolet protection factor (UPF) is achieved, as high as 62.13 with one such LS-treated nylon fabric. The LS-treated nylon fabrics were characterized using FTIR, FESEM, Energy dispersive X-ray (EDX), and Thermo-gravimetric analysis (TGA) instruments. The UPF and color-strength (K/S) values are signifi cantly increased with an increase in the concentration of LS without any loss of tensile properties and thermal stability. The LS treatment has excellent wash fastness.

Despite the beneficial effects of ultraviolet (UV) radiation on the skin, radiation can cause sunburn, skin aging, allergies and even skin cancer. Textiles can provide effective protection against such damage. Unlike cosmetics, using textiles to protect the skin has only recently been researched. The design and modification of fabrics leading to a high protection against UV radiation is a relatively new application. It is important to consider the kinds of textiles to be used because most of the garments worn during summer, the time of highest exposure, are light and colourless materials that provide the lowest protection. Here, we report the synthesis and characterisation of nanosized zinc oxide particles known to absorb UV light. Sol-gel-based inorganic-organic hybrid polymers were modified with these particles and applied to cellulosic cotton (100%) and cotton/polyester (65/35%) fabrics. These modified inorganic-organic hybrids polymers were based on 3-GPTMS. The complete finishing sol prepared in this work has a marked long stability. The effectiveness of the novel finishing was determined by UV-visible spectroscopy to evaluate the UV protection factor. The influences of the finishing for general textile properties such as tensile strength, elongation, air permeability, degree of whiteness, wear resistance, stiffness and the durability of the treatments were investigated.

In spite of some beneficial effects of ultraviolet (UV) radiation on skin, radiation can cause sunburn, skin aging, allergies and even skin cancer. Textiles can provide effective protection against such damage of UV radiation. Unlike cosmetics, using textiles protecting the skin or at least enhancing protection has only recently been researched. The design and modification of fabrics leading to a high protection against UV radiation is a relatively new application. It is very important to consider the kind of textile to be used, most of the garments worn during summer, the time of highest exposition, are light and colourless materials and therefore provide the lowest protection. We report the synthesis and characterization of nanosized zinc oxide particles known to highly absorb UV light. Sol-gel based inorganic-organic hybrid polymers were modified with these particles and were applied to cellulosic cotton (100%) and cotton/polyester (65/35%) fabrics. These modified inorganicorganic hybrids polymers were based on 3-glycidyloxypropyltrimethoxysilane (GPTMS). Complete finishing sol prepared in this work has remarked long stability for further processing. The effectiveness of the novel finishing was determined by UV-Vis spectroscopy and by evaluation of the ultraviolet protection factor (UPF). The influences of the finishing for some general textile properties as e.g. tensile strength, elongation, air permeability, degree of whiteness, wear-resistance, stiffness as well as the durability of the treatments were investigated.
