Properties of Air Covered Yarn as Influenced by Air Pressure and Delivery Speed: A study for the Extension of Textile Technology

摘要

Air covered yarn was produced from thermoplastic, cellulosic or non organic filament yarns using compressed air. Loops were formed on the surface of the filament yarn, giving it a voluminous character. Depending on the material used, the loop structure results in a yarn with characteristics resembling those of conventional staple fibre yarn. The present study was planned to explore, "Properties of air covered yarn as influenced by air pressure and delivery speed". Following parameters of covered yarn such as delivery speed; air pressure of air nozzle and denier of spandex were studied. The present study should be discussed with the textile experts in the textile industries to find out the solution of the problems they faced, where as the results of the said study must be shared to improve the quality not only but also for eco-friendly in the sense of financial matters.
