Polyester Filament Yarns — FDY & POY
Made-to-order polyester filament yarns for textile manufacturing, including FDY (Fully Drawn Yarn) and POY (Partially Oriented Yarn). Specifications can be produced according to required denier, filament count, lustre, colour and end application.
What Are Polyester Filament Yarns?
Polyester filament yarns are continuous synthetic yarns produced from polyester polymer. Unlike spun yarn, which is made from short staple fibres, filament yarn consists of long continuous filaments.
Different production stages create different yarn types. FDY is fully drawn and ready for direct textile processing, while POY is partially oriented and is normally used as an intermediate yarn for further drawing, texturing or other processing.
FDY — Fully Drawn Yarn
What Is FDY?
Fully Drawn Yarn is polyester filament yarn that has been fully drawn during production to achieve stable molecular orientation and dimensional consistency.
It is generally supplied ready for weaving, knitting and other textile manufacturing processes.
Key Characteristics
- Smooth filament structure
- Good tensile strength
- Dimensional stability
- Low shrinkage options where required
- Consistent processing performance
- Available in different lustres and constructions
Typical FDY Applications
Apparel & Fashion Textiles
- Woven fabrics
- Knitted fabrics
- Linings
- Fashion textiles
- Lightweight fabrics
Industrial & Home Textiles
- Upholstery fabrics
- Home furnishings
- Narrow fabrics
- Industrial textile structures
- Technical applications
POY — Partially Oriented Yarn
What Is POY?
Partially Oriented Yarn is a polyester filament yarn produced with partial molecular orientation.
POY is normally not the final textile yarn. It is commonly used as feed yarn for additional processing such as drawing or texturing.
Typical Uses of POY
- Production of DTY
- Further drawing and texturing
- Specialised filament processing
- Intermediate textile manufacturing
FDY vs POY
| Parameter | FDY | POY |
|---|---|---|
| Full Name | Fully Drawn Yarn | Partially Oriented Yarn |
| Production Stage | Fully drawn and stabilised | Partially oriented |
| Primary Use | Direct weaving, knitting and textile production | Further processing |
| Structure | Smooth continuous filament | Continuous filament requiring additional processing |
| Typical Next Stage | Fabric production | Drawing or texturing, including DTY production |
FDY, POY and DTY — What Is the Difference?
| Yarn | Description | Typical Characteristic |
|---|---|---|
| FDY | Fully drawn polyester filament yarn | Smooth, stable and ready for textile processing |
| POY | Partially oriented polyester filament yarn | Intermediate material for further processing |
| DTY | Draw textured polyester yarn | Bulk, softness, crimp and controlled stretch |

Need Help with the Specification?
If you do not have a complete technical specification, provide the intended textile application and any existing yarn data you have.
We can discuss the requirement with the producing mill and identify suitable manufacturing options.
Made-to-Order Industrial Supply
Elmika supplies polyester filament yarns against customer requirements rather than from standard retail stock.
Once the yarn specification and commercial terms are agreed, production is arranged with the manufacturing mill and the finished yarn is shipped directly to the customer’s nominated destination.
