1, The nature is different: the filament is a continuous fiber, such as silk, and chemical fiber when the continuous filament is sprayed. Short fiber is a length of a few millimeters to tens of millimeters of fiber, such as cotton, wool, hemp, and other natural fibers.

2, The production is different: filament is usually a dozen or dozens of single filaments woven together. Staple fibers are made by cutting filament. Staple fibers must go through the spinning process so that the fibers can be twisted together to form a continuous yarn for weaving.

3.Feel different: filament fabric surface smooth, strong luster, commonly used as a summer fabric. Short fiber fabric surface hair, plump and fluffy, is often used in autumn and winter fabrics. Polyester staple fiber is made of polyester (that is, polyethylene terephthalate, referred to as PET, which is polymerized from PTA and MEG) and then spun into strands after cutting the fiber. Polyester staple fiber split cotton type staple fiber and wool type. Polyester staple fiber is used for spinning, such as yarn, weaving, etc., the polyester filament can usually be divided into POY (pre-oriented filament) FDY (full draft filament) DTY (low elastic filament), and other three categories.
