Polyester staple fiber (PSF)-polyester fiber producer from China
Polyester staple fiber (PSF)is kind of polyester fiber made directly from PTA and MEG or PET chips or from recycled PET bottle flakes
PSF made from PTA and MEG or PET chips is known as virgin PSF and PSF made from recycled PET flakes is calledrecycled PSF
100% virgin PSFis usually costly than recycled PSF and is also more hygienic
Polyester staple fiber is widely used inspinning, weaving nonwoven
PSF is mainly used forfiber fillingsin pillows and sofa
It is also used widely in spinning to make polyester spun yarn which is then knitted or weaved into fabrics

PSF is mainly classified assolid and hollow polyester staple fiber
Hollow PSF can also have some properties likeconjugated, siliconized, slick and dry PSF
These properties are usually represented as HSC (hollow conjugated siliconized), HCNS (hollow conjugate non-siliconized) or slick PSF that has a smooth finish
Depending on the luster, PSF can be classified as semi dull and bright
By mixing color master-batch,dope dyed PSFcan also be obtained in optical white, black and several colors

Polyester staple fiber is available in different deniers with different cut-lengths
It is mainly available in 1.4, 1.5, 3, 6, 7D, 15D and cut lengths like 32, 38, 44, 64mm
PSF is mainly produced in India, China, Taiwan, Indonesia, Vietnam, Malaysia and Korea
