SUMMARY:

Skin protection is the main objective of textiles. Textiles are the barrier between the skin and the environment. Their functionalization with ultraviolet ray blockers does not alter the properties of the yarns, but prevents the skin from absorbing UV-A and UV-B rays. Data regarding the detection of skin cancer in Brazil correspond to 25% of all malignant tumors registered in the country. The main agent is natural ultraviolet radiation, coming from the sun, more precisely UV-B. This study aims to understand the behavior of Jersey knitted fabric functionalized with Anti-UV blockers. For this purpose, three Jersey structures were analyzed and their characteristics and properties investigated regarding the characteristic in the knit, the functionalization and relative permeability to water vapor. The tests were conducted on finished fabrics, the data obtained were evaluated and the results show that the samples are functionalized with Ti02, which is an inorganic, toxicity-free, eco-friendly material that has potential and is used as a UV protection agent. Through SEM analysis, it was diagnosed that the structure and characteristics of the Jersey fabric were not modified after the functionalization of the fabric with UVR, and that the yarns remain woven in the same direction, and that all the samples studied registered permeability to water steam.
