What's the Difference Between Recycled Polyester FDY and DTY? A Guide for Fabric and Textile Buyers

When sourcing polyester yarn, understanding the difference between FDY (Fully Drawn Yarn) and DTY (Draw Textured Yarn) is essential. Whether you're manufacturing garments, home textiles, or industrial fabrics, choosing the right yarn type can significantly impact product texture, appearance, and performance. But what exactly sets recycled polyester FDY and DTY apart—and how do you decide which is best for your needs?

Understanding Recycled Polyester FDY: Smooth, Strong

Recycled Polyester FDY is made through a one-step spinning and drawing process, resulting in fully drawn filaments with high tensile strength and excellent uniformity. It is commonly used in weaving and knitting applications where smoothness, luster, and stability are desired.

Key Features of FDY:

1. High strength and low shrinkage

2. Smooth texture

3. Suitable for weaving applications like suit fabrics, home textiles, and linings

4. Often used where shape retention and clean surface are required

Unpacking Recycled Polyester DTY: Textured, Voluminous, and Soft

Polyester DTY is produced by texturizing partially drawn yarn (POY) through a mechanical process that introduces crimp, bulk, and elasticity to the yarn. This gives it a more cotton-like feel, making it ideal for comfort-focused applications.

Key Features of DTY:

1. Crimped and elastic structure for softness

2. Matte or semi-dull finish, depending on treatment

3. Ideal for garments, especially sportswear and innerwear

4. Excellent comfort properties

If your priority is smooth, durable, and glossy fabrics, FDY may be your best fit. On the other hand, if you’re targeting comfort, breathability, and elasticity, DTY offers the characteristics needed for modern garment production.
