Polyester Staple Fibre (PSF) is kind of Polyester Fibre made directly from PTA & MEG or PET Chips or from Recycled PET Bottle Flakes. PSF made from PTA & MEG or PET Chips is known as Virgin PSF and PSF made from Recycled PET Flakes is called Recycled PSF. 100% virgin PSF is usually costly than recycled PSF and is also more hygienic. Polyester Staple Fibre is widely used in spinning, weaving non-woven.PSF is mainly used for fibre fillings in 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 as Solid & Hollow Polyester staple fiber. Hollow PSF can also have some properties like Conjugated, 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 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.
Polyester Staple Fibre is available in different Deniers with different cut-lengths. It is mainly available in 1.4D, 1.5D, 3D, 6D, 7D, 15D and cut lengths like 32mm, 38mm, 44mm, 64mm.
Flame retardant polyester fiber, abbreviated as FR-PET, refers to the copolymerization, blending or finishing, and other methods to make polyester fiber with non-combustible or non-flammable properties under combustion conditions to achieve the flame retardant effect.
In the chemical fiber market, polyester fiber is the most widely used and has the largest production. But it has the disadvantage of flammability. Flame retardant polyester fiber is a kind of functional fiber specially developed to improve the flammability defect of an ordinary one. It is widely used in apparel, household, decoration, non-woven fabrics, and fillers.
The fiber flame retardant effect of our FR-PET can reach the European standard NF P92-507M1 level. It is a phosphorus copolymer flame retardant. Phosphorus content can reach 6500ppm. The limit of oxygen index is no less than 30. Compared with FR-PET made from flame retardant masterbatch, our flame retardant fiber has more effective phosphorus element content, better dyeing uniformity, lower cost, and better stability.
FR PET Fabric Characteristics
1. Excellent and permanent flame retardant properties
It has good performance in preventing flame spread, smoke release, melt resistance, and durability, meeting the requirements of flame retardant fabrics in the fields of decorative materials, automobile interiors, old and young clothing, workwear, and militaery canvas tents, etc.
2. Distinctive varieties series
It can meet the requirements of different customers. Except for the regular bright or semi-dull grade FR PET, advanced varieties also include full-dull grade flame retardant, cationic flame retardant, and melt-resistant drop flame retardant. It can meet the requirements of different customers.
3. Stable and durable flame retardant performance, high dyeing rate, and good dyeing uniformity
