JGT1200D Type Air Jet Texturing Machine For Sale

Air Textured Yarn Drawing Machine has the following functions: it feeds continuous fibers (POY/FDY) such as nylon and polyester into an air texturizing nozzle with a feed roller set at arbitrary speed, interlaces that yarn with air or blends them using turbulence generated by compressed air inside the nozzle, and then produces yarn known as DTY.


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.
