The main function of the false twisting machine is to twist several untight arranged threads into a tight arranged thick thread and increase the elasticity of the thick thread, the false twisting machine is composed of a plurality of false twisting mechanisms, and the main working process of the false twisting mechanism can be divided into four processes of double twisting, heating, false twisting, winding and the like.

The existing false twisters require heating and cooling of the yarn after twisting, which are necessary conditions for achieving false twisting effect by using the thermoplastic property of synthetic fiber. Heating is carried out in the twisting stage in the false twisting process, and the purpose is to eliminate the internal stress generated by twisting by utilizing the thermal motion of molecules so as to fix the twisting deformation. In addition, the plasticity of the strand silk is enhanced after being heated, the rigidity is weakened, the twisting tension can be reduced, and the twisting is convenient.

The purpose of the cooling is to fix the plastic deformation obtained by the twisting deformation. If the filaments in the thermoplastic state immediately pass through a rotating holder (small rotor), untwisting will not work, resulting in stiff filaments with very poor loft. When the fiber is cooled to the second transition temperature (the glass transition temperature is below 81 ℃, the deformation after twisting is solidified, and each monofilament still keeps the original curled shape although untwisted, so that the fiber is fluffy and elastic.

The above prior art solutions have the following drawbacks: because the temperature change of the heating and cooling processes is large, the temperature of the yarn entering the heating device is low, and the hot air in the heating device is contacted with the yarn to easily generate water drops, so that once the yarn absorbs the water drops, various performances of the yarn are changed, and the integral effect of false twisting is influenced.
