What Is Polyester Draw Textured Yarn and How Is It Made?

Polyester draw textured yarn is produced through a mechanical texturing process that imparts bulk and stretch to the fibers. The production begins with partially oriented yarn (POY), which is drawn to align the polymer molecules and increase strength. Simultaneously, it undergoes texturizing, often using false twist texturing methods, to create crimps and loops in the filaments. This results in a soft, voluminous yarn with enhanced elasticity, making it ideal for fabrics that require comfort and flexibility. The process ensures consistent quality and allows for customization based on end-use requirements.

Stages in the production of Polyester DTY:

• Feeding the POY supply into the texturing machine
• Drawing the yarn to orient the polymer chains
• Heating and twisting to set the texture
• Cooling and untwisting to lock in the bulk
• Winding the finished yarn onto packages

Key Properties of Polyester DTY
