The Difference Of Polyester DTY, FDY, POY
POY (Partially Oriented Yarn)
Polyester POY is a fiber obtained through high-speed spinning technology with a certain degree of orientation. Its degree of orientation is between that of unoriented and fully stretched filaments. POY filaments are characterized by good stability, but they are usually not used directly in the final product, but as a special raw material for the manufacture of stretched, false-twisted and deformed filaments DTY.

FDY (Fully Drawn Yarn)
Polyester FDY fiber is fully stretched during the spinning process and have high strength and gloss. The quality of this fiber is stable and suitable for making a variety of high-quality clothing and textiles, such as suit fabrics and shirt fabrics. Due to its excellent physical properties and appearance, FDY is widely used in the textile industry.

DTY (Draw Textured Yarn)
Polyester DTY is a specially treated fiber with stretchable properties. During the production process, DTY fibers are stretched and deformed to give them better elasticity and deformation. This kind of fiber is commonly used in textiles that require deformation, such as stretch clothing and knitwear.

The difference between FDY and DTY Yarn
– Processes of manufacturing: FDY is drawn and DTY is making texture.
– FDY has high strength than DTY because it is fully drawn yarn.
– FDY cannot stretch much as DTY. Some products don’t need a stretch. FDY is more suitable than DTY.
– DTY is softer than FDY because it has a soft crimp texture. The texture will give a soft hand feel. It is usually produced in upholstery or skin-clinging garment.
– DTY has more stretch because texture also gives flexibility as it brings the produce of some items which need stretching.
