The working principle of the one-step false twisting machine is mainly based on the false twisting deformation technology. Through a specific false twisting device, the filament is highly twisted, heat set, and untwisted to produce false twisting deformation yarn. The following is a detailed explanation of the working principle of the one-step false twisting machine:
1、 The principle of false twisting deformation
False twisting deformation is the use of the bending and twisting resistance of the filament itself, which causes the filament to twist back through the action of a false twisting device. During the false twisting process, the filament is highly twisted to form a high twist filament. Subsequently, these high twist filaments undergo heat setting treatment to fix the deformation. Finally, perform untwisting treatment to make the filament appear fluffy and curled.
2、 One step false twisting machine workflow
Raw material preparation: Select suitable long filaments as raw materials, such as polyester, nylon, etc. The quality of raw materials must meet production requirements, including indicators such as fineness, strength, elongation, etc.
False twisting deformation: The filament is highly twisted by a false twisting device. There are various types of false twists, such as rotor type false twists, friction disc type false twists, and ring type false twists. These false twisters use different working principles to twist the yarn back. Rotor type false twisting device: The small rotor is driven by a speed increasing wheel, and the false twisting rotor is adsorbed by a magnetic steel component with strong magnetic force to twist and deform the processed wire.
Friction disc false twisting device: controls twisting torque and filament tension by controlling sliding.
Twisting ring type false twisting device: Two twisting rings overlap and rotate around their respective axes at opposite speeds, applying pressure to the filament to achieve twisting.
Heat setting: Twisted filaments undergo heat setting treatment to fix deformation. The temperature and time for heat setting should be set according to the yarn material and process requirements.
Twisting: After heat setting, the filament is subjected to untwisting treatment to give it a fluffy and curled effect.
Winding: The untwisted filament is wound to form a finished product of false twisted deformed yarn.
3、 Key parameter control
In the production process of one-step false twisting machine, the control of key parameters is crucial for product quality. These parameters include:
Twist: Twist is an important parameter for false twist deformation yarn, which should be set reasonably according to the yarn variety and specifications to avoid excessive twisting causing yarn breakage.
Tension: During the heat setting and winding processes, the tension of the yarn should be appropriately controlled to avoid excessive stretching or relaxation due to excessive or insufficient tension.
Temperature: The heat setting temperature needs to be set according to the yarn material and process requirements. Too high or too low can affect the deformation effect and stability of the yarn.
Time: The length of the shaping time can also affect the deformation effect of the yarn, and should be adjusted according to the yarn specifications and process requirements.
4、 Application Fields and Market Demand
False twisted deformed yarn is widely used in textiles, clothing, home textiles and other fields, which can enhance the fluffiness, elasticity and hand feel of fabrics. With the increasing demand for textile quality from consumers, the market demand for fake twisted yarn is constantly growing and has broad market prospects.
In summary, the one-step false twisting machine uses specific false twisting devices and process flow to process long filaments into false twisting deformed yarns with fluffy and curled effects. The control of key parameters is crucial for product quality in the production process. Meanwhile, false twist deformed yarn has broad application prospects in the fields of textiles, clothing, home textiles, and more.
