The Practical Application of Alumina Ceramic Rods in the Textile Industry
I. Yarn Guide and Thread Guide Rod
1.Application in High-speed Yarn Guiding
As the core component of the yarn guide, the alumina ceramic rod is applied in processes such as high-speed winding and texturing. Its high hardness (Mohs hardness grade 9) and surface finish can significantly reduce the friction between the silk thread and the yarn guide, minimize the generation of static electricity, and avoid the accumulation problem of "white powder" caused by the adsorption of impurities due to static electricity. Thus, it can improve the quality of the silk thread and reduce the rate of broken threads. For example, the alumina ceramic yarn guide rods produced by Henan Jiyuan Xiongdi Materials Co., Ltd. have been used in automatic winders, replacing the traditional metal materials and extending the equipment maintenance cycle.
2.Precise Tension Control
In the wire tensioner and winding device, the alumina ceramic rod ensures the uniformity of the yarn tension through its high wear resistance and chemical stability. Its low coefficient of thermal expansion can maintain dimensional stability during high-speed operation, avoiding the deformation problem caused by the rise in temperature.
II. Rotating Components and Driving Parts
1.High-precision Ceramic Roller Rods
Alumina ceramic rods are used as rotating components in the processes of yarn stretching, winding, and texturing. For example, in chemical fiber production equipment, the ceramic roller rods undergo ultra-precision surface processing to reduce yarn entanglement failures. Meanwhile, their low density can reduce the inertia during high-speed rotation, saving energy consumption.
2.Driving Parts of Rapier Looms
The driving pinions of rapier looms are made of alumina ceramic rods. Compared with metal materials, their wear resistance is increased by 3 to 5 times, and their dynamic friction coefficient is low, making them suitable for scenarios of high-speed reciprocating motion and significantly reducing the frequency of equipment maintenance.
III. Friction Disk and Yarn Cutting Apparatus
1.Ceramic Friction Disk Support Shaft
As the support shaft of the friction disk, the alumina ceramic rod bears high-frequency frictional loads in the winder. For instance, a ceramic rod made of 99% alumina can withstand a high-temperature environment below 1200°C. Even after long-term use, it can still maintain the stability of its surface structure, avoiding fluctuations in yarn quality caused by wear and tear.
2.Yarn Cutting Scissors Assembly
In the yarn cutting device of the automatic winder, the alumina ceramic rod serves as the fixed shaft or transmission component of the scissors. By taking advantage of its anti-adhesion property and chemical inertness, it prevents the attachment of yarn residues and ensures the accuracy of the cutting action.
