ATY can offer an entirely different look and hand to any fabric. It can be used in a very broad range of fabrics from simple lightweight scrim all the way to very heavy duty soft luggage fabrics, from lightweight swim wear to heavy weight parkas. Several filament yarns can be mixed to construct the ideal ATY for a certain endues. ATY is a rather expensive yarn if the denier is low. But higher deniers compare very favorable with competitive spun yarns.
ATY yarns are made from POY, ATY is a yarn with zillions of small loops, which give it a distinct feeling and look whereas DTY is a yarn with preferably no loops at all. The loops in ATY contribute to the bulk and loft of a fabric, whereas in DTY the even crimp in every filament creates the bulk and volume of a fabric.
One or more ends of filament yarn are overfed at a constant rate to a special air jet, which blows, depending on the amount of overfeed between the inlet and outlet feeds, the yarns into a continuous string of smaller and larger loops. Similar as in the tangling of yarns the center of the ATY becomes randomly braided. The individual filaments are compacted by the air stream, which stabilizes the loops.
