PET, PA, PP |
I. Overview
FDY (Fully Drawn Yarn): One-step fully drawn process; high tenacity (≥3.5 cN/dtex); high equipment investment; relatively high energy consumption; directly used for weaving (e.g., silk-like fabrics, high-speed weaving warp yarns).
POY (Pre-Oriented Yarn): Semi-finished product requiring texturing; elongation >50%; low tenacity; requires secondary processing; primarily used as feedstock for DTY (e.g., stretch fabrics for apparel).
HOY (Highly Oriented Yarn): High elongation; limited end-use performance; produced via ultra-high-speed spinning at lower cost; serves as a substitute for staple fibers (e.g., carpets, nonwovens).
