,Circular Array Spinneret
Annular (ring-type) Lyocell spinneret plates feature specialized circular hole arrangements designed specifically for optimized cellulose-NMMO solution distribution in Lyocell fiber production. These precision-engineered spinnerets utilize concentric circular patterns that provide superior fiber distribution, uniform quenching characteristics, and enhanced process stability. The annular design facilitates better airflow management, more efficient solvent evaporation, and improved fiber properties in the environmentally-friendly Lyocell production process.
