Functions of Textile Ceramic Discs

– This Textile ceramic discs have yarn guiding and conveying function ：
In textile machinery, textile ceramic discs often play a crucial role in guiding yarn. Generally, the surface of the disc is equipped with precise wire grooves or yarn guiding grooves. Yarn can move smoothly and orderly along these grooves to ensure accurate conveyance from the yarn bobbin to the textile processing area.

– Our Textile ceramic discs have wear resistance and protection function：
 In the textile production process, there is continuous friction between yarn and the disc. Ceramic discs, with their excellent wear resistance, can withstand this friction for a long time without easily generating surface wear, scratches, and other conditions. This not only guarantees the service life of the disc itself and extends the maintenance cycle of textile equipment, but also avoids adverse effects on yarn quality caused by rough or damaged disc surfaces.

Physical performance characteristics of Textile Ceramic Discs:

  1. High temperature resistance:
    Some textile processes may involve high-temperature environments, such as heat treatment of yarn. The ceramic materials used in textile ceramic discs mostly have good high-temperature resistance. For example, silicon nitride ceramics can still maintain stable mechanical properties at high temperatures without softening or deforming, enabling the disc to adapt to various different textile processes and broadening its application range.
  2. Low density:
    Compared with similar parts made of some metal materials, the density of textile ceramic discs is usually lower. This characteristic means that when installed and used in textile equipment, it will not add excessive weight burden to the rotating system of the equipment, helping the equipment operate flexibly, reducing the power consumption during equipment operation, and also facilitating the overall structural layout and installation and debugging operations of the equipment.
  3. High surface smoothness:
    After fine processing, the surface of textile ceramic discs can reach a very high smoothness. This is conducive to the smooth sliding of yarn on its surface, reducing unnecessary frictional resistance between yarn and the disc. It can not only make the yarn run more smoothly, reduce the probability of yarn fluffing and breakage, but also assist in adjusting the tension of yarn so that it has a more appropriate and stable tension state when entering subsequent textile processes.

Chemical performance characteristics of Textile Ceramic Discs:

  1. High chemical stability:
    Ceramic materials have strong tolerance to common chemical substances such as acids, alkalis, and salts. In the textile production process, even if in contact with textile auxiliaries (such as dye liquor in the dyeing process, which may contain acidic or alkaline substances), chemical reagents for cleaning, or in a workshop environment with certain corrosive gases, textile ceramic discs will not react chemically with them and be corroded or damaged.
  2. Good oxidation resistance:
    When exposed to an aerobic environment such as air for a long time, textile ceramic discs will not be prone to oxidation reactions like some metal materials. There will be no situations such as the generation, thickening, or peeling of oxide films that affect their performance and appearance.
