Background technique

More than 90% of the post-processing of chemical fiber pre-oriented yarn adopts the stretching deformation process. The equipment for the stretching deformation process is called a texturing machine, and the false twist spindle is the key component of the texturing machine.

At present, most pre-oriented yarns on the market use friction discs or aprons for false twisting, which is characterized by high efficiency, but friction discs or aprons will cause more or less damage to the yarn and affect the quality of the yarn. Therefore, this type of equipment is mainly used to produce low-cost, popular clothing fabrics and other textiles.

Some pre-oriented yarns are false-twisted by using a rotor-type false twister. Although the efficiency of this equipment is relatively low and the cost is high, it can ensure the high quality of the yarn, and can generally be used to manufacture high-grade, high-value-added clothing fabrics.
