Draw Winding and POY Processing Machinery
category
Draw winding and POY processing machinery draws partially oriented yarn produced by melt spinning at intermediate speeds to develop full orientation and crystallinity in the polymer structure, producing fully drawn yarn with defined tenacity, elongation, and thermal stability for applications requiring fully oriented filament properties in yarn for weaving, knitting, and industrial textile use without the texturing crimp geometry of draw-textured yarn.
Role
Provides the drawing process that develops the full mechanical properties of synthetic filament yarns from the partially oriented precursor produced at intermediate spinning speeds, enabling the separation of spinning and drawing operations that improves spinning productivity while maintaining yarn property quality through controlled draw ratio and temperature application in separate draw winding machines for flat yarn production.
