Polyester yarns are a cornerstone of the textile industry, offering durability, elasticity, and cost-effectiveness. Among the various types, Polyester Partially Oriented Yarn (POY), Fully Drawn Yarn (FDY), and Draw Textured Yarn (DTY) serve distinct roles in fabric production.

POY Yarn Series

What Are Polyester POY Yarns?

Polyester POY (Partially Oriented Yarn) is a semi-processed filament yarn produced through high-speed spinning. It has moderate molecular orientation but requires further drawing or texturing to enhance its strength and elasticity.

Key Features of POY Yarns:
Intermediate Product: Used as a precursor for DTY and FDY.
High-Speed Production: Cost-efficient due to rapid manufacturing.
Soft & Smooth Texture: Ideal for further processing.

Comparing POY with FDY and DTY Yarns

1. Polyester FDY (Fully Drawn Yarn)
Fully Oriented: Unlike POY, FDY undergoes complete drawing during production.
High Strength & Low Elongation: Suitable for woven fabrics, linings, and industrial textiles.
Uses: Apparel, home textiles, and technical fabrics.

2. Polyester DTY (Draw Textured Yarn)
Textured & Elastic: Made by drawing and crimping POY, giving it bulk and stretch.
Soft & Voluminous: Used in knitwear, sportswear, and upholstery.
Advantages: Better insulation, comfort, and aesthetic appeal.

Applications of POY, FDY, and DTY Yarns

Yarn Type Primary Uses Key Characteristics
POY (Partially Oriented Yarn)
  • Raw material for DTY production
  • Sewing threads
