RESEARCH OF UV SHIELDING PROPERTIES OF POLYESTER/VISCOSE WOVEN FABRIC

The aim of present work was to develop the fabric which provides shielding from ultraviolet rays present in the sunlight. Carded Polyester/Viscose Ring yarns with Blend ratios 75/25, 60/40, and 55/45 and Polyester/Viscose/Lycra Ring yarns with blend ratio 70/25/5 having linear density of 20 Tex were produced. The fabric samples were woven with constant warp density of 125 ends per inch and for each blend three weft densities (65, 80, 95 picks per inch) were selected. Combining all, twelve different samples of fabric were prepared. These fabrics were first treated with pre-treatment process and then dyeing of all samples were carried out by using disperse dye and reactive dye for Polyester and Viscose respectively. The UPF of the fabric was determined by the in vitro method using an Ultraviolet Transmittance Analyser UV-2000F. Results show excellent UPF along with good air permeability and provide best protection in UVB and UVA region for all the samples.
