EFFECT OF POLIESTER POY FIBRE CROSS-SECTION ON THE YARN PROPERTIES OF AIRJET TEXTURING
Journal Title: Annals of the University of Oradea. Fascicle of Textiles, Leatherwork - Year 2016, Vol 0, Issue 1
Abstract
POY yarns are well know and commercialized since 1970s. On the other hand, air-jet textured yarns are very common due to their unique structure which looks like natural spun-staple yarns. In the air-jet texturing process, the yarn is textured by overfeeding into a high-pressure of air to create a looped and more natural yarn appearance and also the bulkiness level of the yarn is controlled by input speed and jet-take out speed. This process reassigns flat, continous synthetic yarns into entangled, convoluted, bulky, spun like structured yarns. They are of higher bulk, exhibits increased covering power, have a more subdued lustre and are warmer in hand. Therefore, air-jet textured yarns possess some unique properties that require investigation. Hence, in this study, first the texturing process is introduced briefly and its principle of manufacturing is illustrated, later four different types of yarns were produced with two different fibre cross-sections at the three different nozzle types and three different core yarn feeding. The produced yarn production details are given and their breaking strength, elongation and work of rupture are studied along with their morphological structures by using light microscope and SEM. The aim of this study is to investigate the effect of POY fibre cross-section on air-jet textured yarn mechanical properties. The overall results showed that coarser air-jet textured yarns with a round shape have higher breaking strength, elongation and work of rupture than the trilobal shaped yarns. On the other hand, half matted yarn which was applied TiO2 has also presented better breaking strength and elongation.
