What is the POY,DTY,FDY?

Polyester filament can generally be divided into POY(Partially Oriented Yarn),FDY(Fully Drawn Yarn) DTY(Drawn Textured Yarn) three categories.

1,POY(Partially Oriented Yarn)

POY receives the orientation degree of high-speed spinning in orientation between the wire and tensile wire not completely stretch of chemical fiber filament.Compared with undrawn yarn, it has a certain degree of orientation, good stability, often used for tensile false twist textured yarn (DTY) special wire.

POY is mainly used in texturizing to make textured yarn, also known as Polyester Drawn Textured Yarn (DTY). POY can also be used in draw warping for weaving and warp knitting of fabrics.

POY yarn is available in different lustre like Semi-Dull POY and Bright POY. T


Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted & drawn and have a certain flexibility. DTY yarn is mainly used in weaving & knitting of fabrics for making clothes, home furnishings, seat covers, bags and many other uses.

DTY yarn can be in Semi Dull or Bright or Trilobal Bright depanding upon the type of sections of filaments.

Polyester DTY yarn can also be obtained in various colors by the dope dyed technology or by conventional dyeing.

3,FDY(Fully Drawn Yarn)

It is also know as Polyester Filament Yarn (PFY) or Spin Draw Yarn (SDY). FDY traditionally called filament is mainly used as weft or weaves in making fabrics. , its gloss good, no curled up, elongation is small.

FDY yarn is mainly available in 3 lustre - Semi-dull (SD), Bright (BR) having circular section & Trilobal Bright (TBR) having triangular cross-sections.
