Investigation on comfort properties of plasma treated polyester fabrics

Abstract

Thermal comfort is the factor governed by the movement of heat, moisture and air through the fabric. The maintenance of thermal balance is probably the most important attribute of clothing and has drawn the attention of many textile workers. The main problem associated for thermal comfort is the incompatibility between the requirement of heat conservation during low metabolic activity and heat dissipation at high energy level. There are numerous factors regarding conditions of thermal comfort, such as age, sex, adaptation, season and heat-flow conditions as well as physical conditions existing next to skin surface. newlineThis research focuses on the thermal comfort and moisture management behavior of polyester respect to the type of the yarn (spun, micro denier, continuous filament and hollow), linear density of the yarn (111 dtex and 166 dtex), and the loop length of the knitted fabric (0.25 cm, 0.27 cm and 0.29 cm). The oxygen plasma treatment also carried out to study improvement in the thermal comfort behavior of polyester fabrics. The air permeability of continuous filament yarn fabric and micro denier yarn knitted fabrics were noticed to be higher than the spun yarn knitted fabrics. The 150D micro denier yarn fabric has the highest air permeability and 100D spun yarn fabric newline
