Spinnerets are the core precision components in the chemical fiber spinning process. Specifically designed for melt spinning of thermoplastics such as polyester, nylon, and polypropylene, these critical tools shape polymer melt into continuous filaments. They are essential for producing high-quality fibers used in sportswear, industrial filtration fabrics, synthetic leather, and high-performance specialty yarns.
Technical Advantages
Ultra-High Machining Precision: Leveraging proprietary manufacturing techniques, we deliver exceptional hole geometry accuracy. Our circular hole diameter tolerance can reach ±0.001mm, while slit width accuracy for profiled holes is maintained at ±0.001mm, ensuring uniform melt flow and consistent filament denier.
Diversified Capillary Design: Beyond standard round holes, we specialize in a wide array of profiled designs (e.g., triangular, Y-shaped, flat, cross). By altering the fiber cross-section, our spinnerets enable unique fabric properties such as enhanced luster, soft hand-feel, moisture management, and improved bulk.
Superior Surface Finishing: We offer various surface finish options, including mirror, matte (sandblasted), and super-mirror. Additionally, functional coatings (such as CrN, TiN, TiC) can be applied to significantly enhance wear resistance, improve melt wettability, extend cleaning cycles, and ultimately reduce your operational maintenance costs.
Key Specifications
Materials
Manufactured from high-quality, corrosion-resistant and high-temperature-resistant materials, including Stainless Steel (e.g., 304, 316) and Hastelloy, ensuring durability under high-pressure spinning conditions.
Micro-Hole Machining Capabilities
Round Hole Diameter: As small as Φ0.02mm – Φ0.06mm
Profiled Slit Width: Can be as narrow as 0.04mm, supporting complex multi-lobal and composite designs
Surface Roughness: Inner walls of capillaries and the spinning surface achieve an extremely low roughness (e.g., Ra ≤ 0.2 μm), guaranteeing stable spinning performance and minimizing filament breakage
Process Compatibility
Fully compatible with major melt spinning processes, including FDY (Fully Drawn Yarn), POY (Partially Oriented Yarn), and BCF (Bulked Continuous Filament).
Why Choose Us
With decades of precision engineering experience and continuous innovation, we do not just manufacture spinnerets; we provide comprehensive fiber solution consulting. From initial capillary design and material selection to advanced surface treatments, we collaborate with you to achieve your desired fiber properties and production efficiency. Whether for standard apparel textiles or specialized industrial applications, our spinnerets are engineered to deliver optimal performance and superior production yields.
