In order to prevent or reduce the effects of UV on the human body, there are several ways to protect skin from UV exposure, such as cosmetics, lotions and clothing, but each of them have their own pros and cons, such as the formation of cosmetic allergies, dislike of aromas, and lack of air proof and dislike of textile composition and temperature proof. So much emphasis is placed on natural products and materials, which for humans has minimal risk, good optical properties of UV radiation weakening and air permeability. It is known that Succinite possesses excellent optical properties and non-allergenic properties. The aim of this work is to compare optical absorbency of materials with different combinations of natural fibers and fibers with Succinite microparticles, and their ability to reduce the exposure in UV range 280-400 nm. To compare optical absorbency in UVB (280–315 nm) and UVA (315 400 nm), as well calculate of the ultraviolet protection factor UPF both before and after laundering of the treaded samples. Application of Succinite microparticles treatment of cotton and polyamide/cotton blend fabrics UV protection is studied. The effectiveness of the treatment is assessed using the standardized tests, such as UV-V is spectrophotometry (using spectrophotometer UV – Vis Thermo Spectronic Heλios) and the calculation of the ultraviolet protection factor UPF both before and after rinsing of the trodden samples. UPF were calculated according to AATCC Test Method 183. It is found that the performance of Succinite particles as UV-absorbers can be efficiently transferred to fabric materials through the impregnation. The UV tests indicate a significant improvement of UV absorbing activity of Succinite treated textiles.
