Texturing Machine Stretch Ratio:
The draw ratio is generally determined by the residual draw ratio of POY, which directly affects the fineness, strength and elongation of the silk. With the increase of draw ratio, the strength of the filament increases, the elongation decreases, the crimp rate is low, and the crimp stability increases. This is mainly because with the increase of the draw ratio, the macromolecules of the fibers are stretched and aligned along the fiber axis, the orientation degree of the drawn filaments increases, and the crystallization of macromolecules is induced at the same time, thereby increasing the strength of the filaments. Due to the increase in the degree of orientation of macromolecules in the fiber at high draw ratios, the possibility of further stretching decreases, so during the drawing process, the ability to be re-stretched decreases; in addition, due to the increase in the draw ratio, the tension High limits the rapid displacement required for the development of fiber crimps, and the fibers are densely crimped, so the crimp rate decreases and the crimp stability increases. If the stretching ratio is too low, the tension is small, and it is easy to fluctuate and slip, resulting in tight twist. Therefore, appropriately increasing the draw ratio within a certain range can stabilize the twisting, the difference between the spindles is small, the A rate of dyeing is increased, and the difference in post-processing can be reduced. For single slender fibers, the stretch should not be too large, and the adjustable range is relatively narrow.

Application of an auto-doffing device allows less manpower to be needed and for the yarn to be maintained at the specified length. These features suit application to warp yarn. Special yarn such as differential shrinkage yarn for use in peachskin-like fabrics and slub yarn (knubbed yarn) for splash-pattern fabrics can also be produced depending on the specifications of the machine used.

Nylon ATY is often used in sportswear, umbrellas and bags.

Fabric woven with this yarn has been utilized in famous sports brands and is well-known all over the world.

Air-jet texturising process is a purely mechanical method that uses a cold air-stream to produce bulked yarns of low extensibility. The feed yarns need not be restricted to the synthetic filament yarns. The air-textured yarns resemble spun yarns in their appearance and physical characteristics. The air-jet texturising process is by far the most versatile of all the yarn texturising methods in that it can blend filaments together during processing.

polyester high stretch yarn make garments whose shapes do not get distorted, mainly after washes. polyester high stretch yarn can be washed by machine or by hand and make the best components of projects to generate warmth, such as knitted/crocheted baby blankets

When polyester high stretch yarn are used on their own or along with others in blended form, polyester is good at increasing your beloved projects’ stability and durability. polyester high stretch yarn are the best options for making outerwear clothing and accessories that are heavily used and washed, such as scarves, hats, and gloves. polyester high stretch yarn can also be used in the making of various household items such as cup holders, bath rugs, and washable upholstery.
