Polyester Fully Drawn Yarn / Polyester Filament Yarn : FDY
Polyester FDY is the abbreviation for Polyester Fully Drawn Yarn. It is also know as Polyester Filament Yarn (PFY) or Spin Draw Yarn (SDY). It is produced by a process similiar to POY manufacturing except that the yarn is produced at higher spinning speeds coupled with intermediate drawing integrated in the process. This allows stabilisation through orientation and crystallization. FDY is mainly used as weft or weaves in making fabrics. FDY can be knitted or woven with any other filament yarn to get fabric of various different varieties. It is mainly used in Home Furnishing Fabrics, Fashion Fabrics, Denim, Terry Towel and others.
