IT IS ABOUT POY AND FDY YARN .

1. Introduction to POY Yarn and FDY Yarn Discover the fascinating world of POY yarn and FDY yarn. Learn about their production processes, features, applications, and the key differences between them. BY SAMIR

2. Definition of POY Yarn POY yarn, or Partially Oriented Yarn, is a filament yarn made from polyester or silk, characterized by its low twist and high strength.

3. Production Process of POY Yarn 1 Polymer Melting The polyester or silk polymer is melted to form a viscous liquid. 2 Extrusion The polymer is extruded through spinnerets to form continuous filaments. 3 Hot Stretching The filaments are stretched and heated to align the polymer molecules for increased strength.

4. Features and Advantages of POY Yarn Softness POY yarn has a smooth and soft texture, making it ideal for comfortable clothing. High Strength POY yarn exhibits excellent strength properties, ensuring durability in various applications. Good Elasticity It has moderate elasticity, providing flexibility and comfort in fabrics.

5. Definition of FDY Yarn FDY yarn, or Fully Drawn Yarn, is a type of filament yarn that is stretched or drawn to achieve better properties like improved strength and resilience.

6. Production Process of FDY Yarn 1 Polymer Melt Spinning The polymer is melted and extruded through spinnerets to form continuous filaments. 2 Hot Drawing The filaments are stretched using heat or steam to orient the polymer molecules for enhanced properties. 3 Cooling and Winding The stretched filaments are rapidly cooled and wound onto bobbins for further processing.

7. Applications and Differences between POY and FDY Yarn 1 POY Yarn Applications POY yarn is commonly used in textiles, such as apparel, home furnishings, and automotive fabrics. 2 FDY Yarn Applications FDY yarn finds versatile applications in products like clothing, upholstery, and industrial fabrics. 3 Key Differences POY yarn has lower tenacity and elongation compared to FDY yarn, while FDY yarn offers better dyeability and higher abrasion resistance.
