Ultra-High Wear Resistance
With extremely high hardness and abrasion resistance, 99% alumina ceramic significantly outperforms metal or plastic eyelets, greatly reducing replacement frequency.
Low Coefficient of Friction
The smooth surface (polished to Ra ≤0.2μm) minimizes resistance to yarn/filament movement, preventing fuzz formation and yarn breakage, ensuring consistent textile quality.
High Temperature & Chemical Stability
Operates reliably at high temperatures (>1000°C long-term), resistant to acids, alkalis, and oxidation, with no chemical reaction to processed fibers.
Pink Appearance
The pink color is not only aesthetic but also useful for visual line identification (e.g., distinguishing different processes or sizes) without affecting any functional performance.
Precision Forming
Smooth, burr-free hole edges with tolerance controlled within ±0.02mm, ensuring precise and consistent thread paths.
Synthetic fiber spinning (polyester, nylon, spandex, etc.)
Fiberglass and carbon fiber manufacturing
High-speed texturing machines, two-for-one twisters, splicing machines
Sewing thread and industrial yarn coating lines
