FDY (Full Draw Yarn) is a synthetic fiber filament with high orientation and moderate crystallinity, obtained by incorporating a stretching process during the spinning process. FDY exhibits high strength, stability, and elasticity, making it widely used in clothing production and home textile products. Additionally, its good breathability and durability enhance clothing comfort and reduce the likelihood of deformation. Furthermore, Polyester Full Draw Yarn can also be utilized for the production of various industrial materials, such as tire cords and conveyor belts.
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.
FDY boasts a wide range of applications owing to its diverse excellent properties. In clothing fabrics and home textiles, FDY 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.
