polyester filament and staple difference, polyester fiber filament and staple two types.Polyester filament, is the length of more than a kilometer of silk, filament winding into a group.Polyester staple fiber is a few centimeters to ten centimeters of staple fiber.

Polyester filament, is made of polyester filament.Polyester is one of the most important synthetic fibers and is the commodity name of polyester fiber in China.It is terephthalic acid (PTA) or terephthalic acid dimethyl ester (DMT) and ethylene glycol (MEG) as raw materials, through esterification or transesterification and condensation reaction of the preparation of fiber high polymer - polyethylene terephthalate (PET), made of fiber by spinning and post-processing.

Polyester staple fiber is made from polyester (i.e., polyethylene terephthalate, PET, polymerized by PTA and MEG) and then spun into the fiber after cutting the tow.Polyester staple, cotton type staple and wool type.


Polyester staple fiber is used for spinning, such as making wool, weaving and so on;Polyester filament can be generally divided into three categories: POY (pre-oriented filament), fdy (fully drawn filament), and DTY (low-elastic filament).POY is mainly used for post-processing production, such as production of DTY, DT and ATY. It can also be directly applied to the silk textile industry.FDY is mainly used in the garment and textile industry.DTY is an ideal raw material for knitting (weft knitting, warp knitting) or machine knitting, suitable for making clothing fabrics (such as suits, shirts), bedding (such as quilt cover, bedspread, mosquito net) and decorative articles (such as curtain cloth, sand cloth, wall cloth, automobile interior decoration cloth).

Long fiber like silk, short fiber like cotton, the same long fiber and short fiber, of course, short fiber cloth feel soft, and generally with a point of wool.Filament cloth made stiff, elastic silk made soft, each has its own characteristics, filament elastic silk can be mixed weave, interweave.
