FDY, or Fully Drawn Yarn, is a continuous polyester filament that is fully stretched and oriented during spinning. It is also commonly searched as full draw yarn. FDY provides high strength, low elongation, dimensional stability and a smooth, lustrous appearance.
Polyester FDY yarn can be used directly in weaving and knitting for garments, linings, sportswear, home textiles and technical fabrics. Buyers can select the yarn according to denier, filament count, luster, color, cross-section and final fabric requirements.
1. Production Process
POY (Partially Oriented Yarn) is produced at high speed by spinning molten polyester into yarn that is only partially stretched. It requires further processing like texturizing or drawing before use.
FDY (Fully Drawn Yarn) is made by stretching POY to full orientation during spinning, giving it maximum strength and stability. It is ready for direct use in weaving or knitting.
2. Physical Characteristics
POY has lower tensile strength, higher elongation, and a dull or slightly cloudy appearance.
FDY offers higher tensile strength, low elongation, and a smooth, lustrous finish.
3. Usage
POY is mostly used to produce Draw Textured Yarn (DTY) for fabrics that require elasticity and bulk.
FDY is used directly in manufacturing of fabrics for garments, home textiles, and technical applications.
Full draw yarn boasts a wide range of applications owing to its diverse excellent properties. In clothing fabrics and home textiles, full draw yarn is frequently utilized for the production of sportswear, underwear, swimsuits, bed sheets, curtains, and more, thanks to its high strength, wear resistance, ease of cleaning, and wrinkle resistance. Additionally, FDY is also employed in the production of various industrial textiles, such as seat belts and conveyor belts. Furthermore, FDY can be utilized for the creation of decorative materials like wallpaper, carpets, and tapestries, catering to diverse styles and needs in interior decoration. Moreover, in other domains, FDY can be used to manufacture products such as ropes, fishing nets, and filters.
High Strength and High Modulus: Full Draw Yarn has high strength and modulus due to sufficient stretching during the spinning process.
Good Stability: Full Draw Yarn has a high elastic recovery rate and is not prone to shrinkage or expansion.
Good Wear Resistance: The fiber surface of Full Draw Yarn is smooth, and the friction coefficient between fibers is small, therefore it has excellent wear resistance.
Easy to Process and Dye: Full Draw Yarn has good processability and dyeability, making it convenient to dye various colors.
Versatile Applications: Full Draw Yarn is widely used in clothing, home textiles, industrial textiles and other fields.
Before requesting a quotation, buyers should confirm the required denier, filament count, luster, color, cross-section, package type and intended textile application. These factors affect yarn appearance, processing performance and the characteristics of the finished fabric.
Smoothness and color consistency are important for linings and decorative fabrics, while strength and dimensional stability may be more important for technical textiles and other performance-oriented applications.
What does FDY mean in textile production?
FDY stands for Fully Drawn Yarn. It is fully stretched and oriented during spinning and can normally be used directly in weaving or knitting.
Is FDY yarn suitable for direct weaving?
Yes. FDY is already fully drawn, so it generally does not require an additional drawing process before fabric production.
What is the difference between FDY and POY?
POY is only partially oriented and normally requires further drawing or texturing. FDY is fully drawn and offers higher strength, lower elongation and greater dimensional stability.
Where is FDY yarn commonly used?
FDY is used in garments, linings, sportswear, curtains, upholstery, home textiles and selected technical textile applications.
