| High Light | Air Gap Spinning Spinneret ，Polymer Spinning Spinneret | ||
Dry-wet spinning spinneret plates (also known as air-gap spinning nozzles or dry-jet wet spinning spinnerets) are precision-engineered components specifically designed for the unique requirements of the dry-wet spinning process. This advanced spinning method, developed in the 1960s, combines the advantages of both dry and wet spinning: the polymer solution is extruded through the spinneret, passes through an air gap (typically less than 30mm), and then enters a coagulation bath.
Our dry-wet spinning spinneret plates are engineered to meet the extreme demands of high-performance fiber production, including aramid (Kevlar®, Nomex®), high-strength PAN precursors for carbon fiber, PBI, PVA, and other super-high molecular weight polymers. These spinnerets enable the production of fibers with exceptional strength and modulus, utilizing larger orifice diameters (0.15-0.3mm) and achieving spinning speeds 5-10 times higher than conventional wet spinning (600-1,200 m/min).
Specialized Orifice Geometry: Engineered to prevent solution dripping and maintain stable filament formation during air-gap transit
Anti-Stringing Design: Minimizes filament breaks during high-speed extrusion through air layer
Controlled Die Swell: Compensates for polymer elastic recovery in the air-gap region
Uniform Flow Distribution: Ensures consistent filament diameter across all holes despite high-speed operation
Ultra-Precise Hole Diameters: ±0.001mm (1μm) achievable for holes 0.03-0.5mm – industry-leading precision
Hole Depth Accuracy: ±0.01mm (special grade) for consistent L/D ratios
L/D Ratio Flexibility: From 1/1 to 25/1 depending on polymer rheology and process requirements
Slot/Capillary Precision: For non-circular holes, slit width tolerance ±0.001mm (special grade)
Premium Alloys: Stainless steel, Hastelloy, and specialized corrosion-resistant materials
Multi-Layer High-Strength Construction: Patented composite structure with titanium alloy high-strength layer, nickel-chromium corrosion-resistant layer, and high-temperature resistant layer for extended service life
Surface Coating Options: Wear-resistant coatings, anti-drip surface treatments specifically for air-gap processing
Thermal Stability: Maintains dimensional precision at operating temperatures up to 300°C+
Anti-Solution-Spreading Design: Specialized plate surface treatment to prevent polymer solution from spreading along the spinneret face – a critical challenge in dry-wet spinning
Optimized Air-Gap Performance: Engineered for consistent filament formation with air-gap distances typically <30mm
High-Speed Compatibility: Designed for spinning speeds of 200-2,000 m/min (up to 5-10* faster than conventional wet spinning)
High-Concentration Solution Capability: Accommodates higher concentration spinning dopes for improved productivity
Extended Service Life: Multi-layer reinforced construction and premium materials
Reduced Filament Breakage: Optimized orifice geometry for high-speed air-gap transit
Consistent Product Quality: Uniform fiber properties from first meter to last
Lower Energy Consumption: Optimized pressure drop across distribution system
Minimized Downtime: Reduced cleaning frequency with anti-fouling surface treatments
