A comprehensive study on the general performance properties of Viloft-blended knitted fabrics

Viloft fiber is used frequently in sportswear and underwear in recent years. The purpose of this study is to determine the advantages of Viloft blends used for sportswear, taking into account objective measurements and subjective wear trials. In the study, 1 x 1 rib-knitted fabrics were produced from 20 tex yarn made by blending Viloft fiber and natural, synthetic, or functional fibers. 100% cotton, 100% viscose, and 100% Coolmax, the most preferred fabrics for sportswear were produced as well. Tight-fitting T-shirts with short sleeves and round neck were produced from these fabrics. Physical, mechanical, and transfer properties of the fabrics were measured. Besides, wear trials were conducted with five volunteers using the T-shirts, and mean skin temperature, microclimate relative humidity, and pulse rates were measured. According to the results, the mechanical properties of Viloft-blended fabrics have not been superior than commercial fabrics. Viloft/wool fabrics showing high thermal resistance and water vapor resistance have had poor transfer properties. Viloft/Coolmax fabrics with low water vapor resistance and high moisture management properties have come to the forefront in terms of liquid moisture comfort among Viloft-blended fabrics. It has been observed that knitted fabrics produced by blending Viloft/wool are not preferable options for sportswear. Viloft/Coolmax, Viloft/Thermolite, and Viloft/polyester fabrics have been advantageous for all activity levels.
