Product Details
This Ceramic Air Jet Nozzle Complete Set is a core component for DTY (Draw Textured Yarn) False Twist Texturing Machines. The nozzle insert is manufactured using a precision dry-pressing and high-temperature sintering process with Alumina (Al₂O₃), ensuring excellent dimensional consistency, structural uniformity, and long-term operational stability.
The air jet mechanically intertwines continuous filaments to create the desired interlaced structure, ensuring optimal yarn tightness, improving winding quality, and minimizing filament and yarn breakage during subsequent processing.
Bore shape options: circular or elliptical, matching network nozzle ceramic design requirements.
