Detailed FDY and DTY processes

Everyone who is engaged in the textile industry often sees words such as FDY and DTY in the fabric, and it is difficult for newcomers who are new to the industry to distinguish the difference between the two. FDY and DTY are actually spinning processing methods, not specifically referring to a certa... read more

Harm of elastic silk exposed in fabric

First, the formation of elastic silk exposed 1. Air twist knot: 1) For rovings of 20 or less, because the content of spandex yarn is low, it is better covered in air twisting, so it generally does not appear. 2) More than 30 yarn counts. Because the yarn counts are thinner and have a higher content ... read more

High tensile strength and elastic modulus of DTY

Draw texturing yarn(DTY) is an ideal raw material for knitting or woven processing. It is a textured yarn type of polyester chemical fiber. In addition to general polyester, it has high breaking strength and high modulus of elasticity, excellent heat setting, good resilience, heat resistance, In add... read more

Relation Between POY, DTY, POY and FDY

POY Refers to incompletely drawn chemical fiber filaments with a degree of orientation obtained by high-speed spinning between unoriented and drawn yarns. Compared with undrawn yarn, it has a certain degree of orientation and good stability. It is often used as a special yarn for drawn textured yarn... read more

DTY quality evaluation

The quality indicators of polyester DTY(draw texturing yarn) include physical indicators and appearance indicators. The main quality indicators are introduced below. I. Strength and Elongation As for the strength of the fiber, it is not as high as possible. For example, the damage of polyester fabri... read more
