Comprehensive Analysis of DTY and FDY Polyester Yarn

Polyester yarn is one of the most widely used materials in the textile industry, among which DTY (low-stretch yarn) and FDY (fully-drawn yarn) are the two most representative types of yarn. Many buyers often face doubts during the selection process: What is the difference between DTY and FDY? Which one is more suitable for my needs?

What are DTY and FDY polyester yarns?

DTY (Draw Textured Yarn, low-stretch yarn)

DTY is a polyester yarn that has been stretched and deformed. It has good elasticity and fluffiness, soft surface feel, and is suitable for weaving elastic fabrics.

Features: high elasticity, bulkiness, skin-friendly and comfortable.

Applications: widely used in clothing, home textile fabrics, sports goods, such as sportswear, blankets, curtains, etc.

FDY (Fully Drawn Yarn, fully drawn yarn)

FDY is a yarn formed by high-speed stretching treatment, with high strength, low elongation, smooth silk and good gloss.

Features: high strength, smooth surface, excellent wear resistance.

Application: Mainly used to make high-quality fabrics, such as satin, curtains, automotive fabrics and industrial fabrics.

The main difference between DTY and FDY

How to choose the right polyester yarn?

Choose by end use

• Clothing fabrics: If elasticity and comfort are required, DTY polyester yarn is recommended. Such as sportswear, underwear, etc.
• High-strength fabrics: If wear resistance and smoothness are required, FDY polyester yarn can be selected. Such as industrial fabrics and automotive fabrics.

Choose by fabric style

• Pursue softness and fluffy: Choose DTY, the fabric is more skin-friendly and comfortable.
• Pursuing smoothness and crispness: Choose FDY, the fabric has more texture and gloss.

Choose according to cost requirements

The prices of DTY and FDY are different. For products that pursue high cost performance, the production cost of DTY is more economical, while FDY is more suitable for high-end fabric production.

Introduction to the production process of DTY and FDY

DTY production process

Polyester slices → Spinning → Stretching → False twist deformation → Winding → Finished product

During the false twist deformation process, the yarn is given elasticity and curling characteristics, giving it a soft and fluffy feel.

FDY production process

Polyester slices → Spinning → High-speed stretching → Winding → Finished product

The FDY process stabilizes the yarn through high-speed stretching, reduces the elongation of the yarn, makes its surface smooth, and improves its strength.
