Products Description

Alumina Textile Ceramic Eyelet is a yarn or wire-guiding component made from high-purity alumina (Al₂O₃) ceramic material. It is commonly used in textile machinery, cable processing, and related industries. Its structure is ring-shaped or tubular, featuring a smooth central hole designed to guide fibers, yarns, or metal wires during high-speed operation, reducing friction and wear. Alumina ceramic is renowned for its excellent wear resistance, high-temperature resistance, and chemical stability, allowing this eyelet to maintain precision and durability in demanding industrial environments over long periods.

Main Performance

High Wear Resistance: Alumina ceramic has high hardness (Mohs hardness of grade 9), effectively resisting long-term friction from yarns or wires and extending service life.
High-Temperature Resistance: Capable of withstanding high temperatures (typically up to 1600°C or higher) without deformation or degradation during high-temperature processing.
Chemical Inertness: Highly resistant to acids, alkalis, and organic solvents, making it suitable for corrosive environments.
Low Friction Coefficient: Smooth surface, often polished, reduces resistance and static electricity generation when yarns pass through.
Electrical Insulation: Provides good insulation properties, suitable for electronic textiles or anti-static applications.
High Mechanical Strength: Excellent compressive and flexural strength, capable of withstanding mechanical shocks and loads.

Product application

Textile Industry: Used as yarn guides in spinning machines, looms, knitting machines, and sewing machines to reduce yarn wear and improve production efficiency.
Cable Manufacturing: Guides copper wires, optical fibers, etc., during wire drawing and coating processes to protect surfaces.
Automation Equipment: Guides ropes or belts in robotic or conveyor systems to reduce friction.
High-Temperature Environments: Suitable for high-temperature applications such as glass fiber production and heat treatment lines.
Medical Textiles: Used in processing equipment for medical sutures or specialty fibers.
Aerospace: Provides precise guidance and durability in the weaving and processing of composite materials.
Electronics Industry: Used in wire insulation coating or micro-coil winding to prevent static buildup.
