Ceramic friction discs for false twisting machines are key functional components. They are primarily used in the false twisting texture process of chemical fiber spinning (such as polyester, nylon, and polypropylene). Their core function is to twist and untwist the moving chemical fiber bundles through high-speed rotation and friction, thereby imparting properties such as fluffiness and elasticity to the yarn. They are indispensable parts for producing high-end textile fabrics (such as imitation cotton, imitation wool, and elastic fabrics).
Main Features
Compared to traditional metal friction discs, ceramic friction discs have significant advantages:
1. Extremely High Wear Resistance: Engineering ceramics (such as alumina ceramics and zirconia ceramics) have extremely high hardness, effectively resisting long-term high-speed friction from chemical fibers, resulting in a service life far exceeding that of metal discs.
2. Stable Coefficient of Friction: The stable coefficient of friction between the ceramic disc and the fiber ensures uniform stress on the yarn throughout the processing, thus guaranteeing the uniformity and stability of the final product quality.
3. Minimal Fiber Damage: The smooth, burr-free surface of ceramics, along with its moderate frictional properties, minimizes cutting or abrasion of individual fibers during processing, effectively reducing fuzz and breakage rates, and improving the strength and quality of the finished yarn.
4. High Temperature Resistance: Ceramic materials can withstand the high temperatures generated during false twisting. Their stable physical and chemical properties prevent softening or deformation under high temperatures.
5. Corrosion Resistance and Antistatic Properties: Ceramic is an inert material that does not readily react with spinning oils or chemicals in the environment, exhibiting excellent corrosion resistance. Furthermore, through special treatment, it can be endowed with a certain degree of antistatic capability, preventing fiber entanglement.
