A study of air permeability and ventilation resistance of fabrics made with air jet textured yarns.

In this study, an investigation of the air permeability and ventilation resistance of the polyester and nylon air jet textured fabrics and 100 % cotton fabrics have been conducted. Twenty-seven fabrics were manufactured by use of Two way Anova with replication experiment. Polyester and nylon 6 air jet textured yarns were used in the weft way and 100%cotton yarn in the warp way for fabric production. 100%cotton fabric was also produced for comparison purpose. The warp of 2/80s cotton yarn was constant for all samples. The fabrics were manufactured by using three different weaves i.e., plain weave, 2/1 twill weave, and 5 end satin weaves with three levels of pick densities i.e., 60, 72 and 84. Air permeability and ventilation resistance of twenty-seven fabrics were tested by using standard testing methods. The test results were analysed statistically by use of Minitab software. Performance of produced air textured woven fabrics were assessed and compared with 100 % cotton fabrics, with respect to air permeability and ventilation resistance characteristics. It has been concluded from this research study that yarn type, type of weave and fabric construction parameter i.e., pick density influences the air permeability and ventilation resistance of the fabrics.
