Air-jet texturing process is by far the most versatile of all the yarn texturing methods in terms of type of yarns, it’s linear density, and variety of effects that can be brought about using the same machine. In this case, the proportional length increase of the hank after being subjected to a high tensile force is the measured variable and criterion for the stability of the yarn structure. Air-jet texturing process is a purely mechanical method that uses a cold air-stream to produce bulked yarns with spun touch and warmth. Air Textured Yarn: Textured filament yarn obtained by overfeeding filament yarn into a turbulent stream of air. For this reason, it was expedient to produce air-textured yarn composed of polyester and polytetrafluoroethylene … 1 0 obj 5 0 obj ATY can offer an entirely different look and hand to any fabric.

They can be broadly divided into single, ply, cord, and rope yarns. The weaves used for calvary twill and elastique are the same. This is confirmed by image analysis of air-textured yarns, the results of online tension measurements and tensile tests conducted on the yarns. But sewing threads can not be produced from polytetrafluoroethylene only, because it is not strong. However, the most important qual-ity parameters of air-textured yarns are: instability; physical bulk; boiling-water shrinkage; size, form and frequency of loops; and tensile properties. Figure 1. Several filament yarns can be mixed to construct the ideal ATY for a certain endues. The air textured yarns closely resemble spun yarns in their appearance and physical characteristics. Air-textured yarn (ATY) is an excellent substitute for the synthetic hand of false twist textured yarns.
