What Is POY Filament Yarn? Uses, Applications & Industry Benefits

By /

“Learn the key uses of POY filament yarns in textile manufacturing, including DTY, FDY, knitting, weaving, apparel, and home textile applications.”

POY (Partially Oriented Yarn) filament yarns are an important intermediate product in the man-made fiber industry, especially for polyester and nylon. They are widely used because of their versatility, cost-effectiveness, and ability to be further processed into various yarn types.

Main Uses of POY Filament Yarns

1. Base Material for Texturizing

  • The primary use of POY is for texturizing into DTY (Draw Textured Yarn).
  • Through draw-texturizing machines, POY is stretched and heat-set to produce DTY, which has:
    • More elasticity
    • Better bulk
    • Softer feel
    • Improved strength
  • DTY is used in apparel, home textiles, socks, sportswear, etc.

2. Warping & Weaving (after drawing)

  • POY can be drawn and used directly in weaving/knitting after conversion into:
    • FDY (Fully Drawn Yarn)
    • HOY (High Oriented Yarn)
  • Applications include linings, sarees, lightweight fabrics, curtains, taffeta, and other woven fabrics.

3. Knitting Applications (after further processing)

  • Used for producing:
    • Circular knit fabrics
    • Warp knit fabrics
    • Tricots and Raschel fabrics

4. Blended Fabrics

  • POY-derived yarns are blended with:
    • Cotton
    • Viscose
    • Spandex (for stretch fabrics)
  • Used in shirts, trousers, sportswear, leggings, etc.

5. Home Textiles & Industrial Textiles

Converted POY yarns (mainly DTY/FDY) are used in:

  • Upholstery fabrics
  • Curtains
  • Bed sheets
  • Carpets and rugs (for pile yarn)
  • Automotive textiles

6. Narrow Fabrics & Elastic Tapes

  • POY + Spandex combinations are widely used in elastic bands, lingerie tapes, and waistbands.

Summary

POY filament yarns are not generally used directly; instead, they serve as the primary raw material for producing DTY, FDY, and other drawn/textured yarns used in a wide range of textile applications including apparel, home textiles, industrial fabrics, and stretch materials.
