JapanPolyester staple fibers (hereinafter referred to as staple fibers) are short fibers obtained by spinning, drawing and cutting polyester (PET) produced by polymerizing PTA and ethylene glycol in a molten state. Because of its wide range of uses and low price, its market has grown rapidly since it entered my country in the 1970s, and it has become an important raw material for textile, clothing, home textiles and other industries.
Measurement method of staple fiber
Denier (denier, abbreviated as D) is a method of expressing the fineness of chemical fibers, which refers to the mass grams per 9000 meters of yarn or fiber at a certain moisture regain. The larger D is, the thicker the fiber is.
The special number (tex, namely tex) refers to the mass grams per kilometer of yarn or fiber at a certain moisture regain. The commonly used unit is dtex (decitex, referred to as decitex), 1dtex=0.1tex.
The conversion method of common unit denier and dtex is: dtex (dtex)=1.11*denier (D), such as 1.56dtex=1.4D
