Abstract

Ultraviolet rays represent a very low fraction of the solar spectrum which damages all living organisms and their metabolisms. Such radiations can cause a variety of symptoms, from basic tanning to extremely malignant skin cancers, fabrics with correct design specification, absorbers, and finishing methods, can play a very important role as a shielding system against the deterious effects of Ultraviolet rays.
This study will stress on bi-layer knitted fabrics because knitted goods of all kinds are widely popular due to their flexibility ability to adjust, stretch when worn to a specific shape and their general comfortable wear. Knitted fabrics are widely used in Sportswear, summer clothes, under wears and Childs' clothes due to their excellent stretch and recovery, porosity, air permeability. Also knitted fabrics especially weft knitted fabrics are easier to be produced, and less cost compared to woven fabrics. Because of this fact, most previous research concerns woven structures that are typically less porous and offer higher protection against UV. The possibility of obtaining knitted fabrics with sufficient UV protection factor is of great interest, however, as knitted fabrics are more suitable for both sports and casual summer fashion garments. Current literature on the UV protection factor of knitted fabrics is very small and mostly concerns fabrics developed in machines with relatively large gauges This study is trying to find a solution for this problem by studying the Influence of weft knitted fabrics Construction with its' different parameters for Protection against Ultraviolet Radiation in sportswear applications.
