The study was interested in nanotechnology and zinc oxide nanoparticles because of their properties that allow us to use them in the production of protective clothing for some groups exposed to the risk of ultraviolet rays, as the researcher treated the cloth under study with three concentrations of nanoscale zinc oxide particles (0.5-0.75- 1 g / ml), as well as the study concerned with improving the knitting techniques in line with the efficiency of the processing performance, as the knitting was carried out with the simple and English connection with three knitting stitch densities (3-5-7 stitches / cm) and then conducting laboratory tests to know the change in the properties of the fabric resulting from the treatment And to determine the best techniques for knitting so that the protective garment can perform its purpose with the highest efficiency and quality, and it is evident from the laboratory analysis that treating the fabric under study with nanoscale zinc oxide particles improves some properties of the cloth such as (softness - durability - high rate of protection from UV rays - resistance to bacteria), where the improvement of these properties increases further. By increasing the concentration of nanoscale zinc oxide particles. It has also been proven that treating the cloth under study with nanometric zinc oxide particles reduces some of the fabric's properties such as (air permeability - impregnation) due to the result of the treatment, where the spaces between the fabric fibers are filled with nanometric zinc oxide particles, which reduces its permeability to air and water, but by an acceptable rate. The research also found that treating the studied fabric with nanoscale zinc oxide particles gives it the property of resistance to bacteria, which increases with increasing the concentration of nanometer zinc oxide particles, and that the difference in the density of the sewing stitches under study affects the value of the UPF protection factor from ultraviolet rays, and this is evident in the simple link where The stitch density (7 stitches / cm) achieves the highest protection. Also, the difference in the type of the sewing joint under study gave a better protection coefficient (UPF) with that of the English L-S joint.
