Polyester Staple Fibre : PSF
Polyesters are made by polymerisation of Purified Terephthalic Acid (PTA) and Mono Ethylene Glycol (MEG). The polymer thus obtained is melt spun and the bundle of continuous filaments obtained by melt spinning is called tow. The tow is subjected to further processes like drawing, crimping, spin finish application and then cut into fixed lengths to get cut fibres almost equal in length to cotton fibres. These cut fibres are known as PSF.
Polyester Staple Fibre is widely used in spinning, weaving non-woven. PSF is mainly used for fibre fillings in pillows and sofa. Depending on the lustre, PSF can be classified as Semi Dull and Bright. By mixing color master-batch, dope dyed PSF can also be obtained in Optical White, Black and several colors.
