Polyester Staple Fiber (PSF) is a material produced from synthetic chemical compounds with various uses in the textile, automotive and furniture industries. The phrase "staple fiber" often refers to natural fiber such as cotton or wool.

Due to the high demand for Polyester Staple Fiber (PSF) in the world's market, PSF is one of the company's top products. TPC is the recognized Polyester Staple Fiber and Spun yarn manufacturer with approximately 233,600 tons annually.

Polyester Staple Fiber (PSF) is made from the polymerization process of polyester material such as PTA (Purified Terephthalic Acid) and MEG (Mono Ethylene Glycol) under a high temperature and pressure. Polymer becomes staple fibers after the spinning and drawing process when cut short according to specific cut length.

Deniers and cut length are the significant factors for Polyester Staple Fiber (PSF). The size and length are related to the end product. Denier could be created in numerous sizes up to POY, such as 1.0/1.2/1.4 D, etc. The cut length can be various. Furthermore, most using cut lengths are 31/38/44/51 mm.

The differences in denier and cut length also affect the difference in-hand feel and product size. The smaller denier and shorter cut length bring a softer and smoother feeling.

There are two types of Polyester Staple Fiber (PSF).

1.Virgin Polyester Staple Fiber (PSF)

Virgin Polyester Staple Fiber (PSF) is made from non-renewable polyester and uses an energy-intensive process. The colors that we provide are:

1.1 Raw White (RW)

RW is a natural color for the polyester did not pass any dyed process.

1.2 Dope Dyed Black (DDB)

DDB is the black color polyester staple fiber. The black master-batch creates the black color since the beginning of the POY process with high-temperature. Therefore, DDB PSF will have non-staining function quality and pale color.

2. Recycled

2. Recycled Polyester Staple Fiber (GPSF)

The colors of recycled polyester staple fiber which TPC provides are:

2.1 Raw White (RW)

RW is slightly different from virgin PSF; its color looks pretty yellow, which is natural from the process.

2.2 Dope Dyed Black (DDB)

DDB for recycled polyester looks similar to virgin PSF. It contains a black master-batch since the process of melting before injecting. For this reason, there is no difference between Dope-Dyed Black virgin PSF and Dope Dyed Black Recycled PSF by vision.

Recycled Polyester Staple Fiber is made from PET/Polyester waste and post-consumer PET bottles.

Recycled polyester, also known as R-PET, is obtained by melting down existing plastic and re-spinning it into new polyester fiber. It is a great way to divert plastic from our landfills and the production of recycled polyester requires far fewer resources than new fibers and generates fewer Co2 emissions.

But there is a mechanical test to detect which one is made from recycled and made from a virgin. It has standardized testing. Typically, the recycled fibers and yarns will be tested by a third party qualified by Global Recycled Standard (GRS), the standard certificate of recycling material, and the tracking process.

PSF luster

Refers to the degree of light reflected from surfaces of fibers or the degree of gloss or sheen that the fiber possesses.

1.Full dull

Semi-dull yarn is manufactured from raw materials with low luster compared to partially oriented bright yarns used to manufacture semi-dull polyester textured yarn.

Full dull yarns are manufactured from raw materials modified chemically and physically to reduce their normal luster. A few of the qualities of full dull yarns are that they have high tenacity and strength and look like cotton fiber. In addition, these yarns are of good pendent, soft visual appeal and a strong covering. Full dull yarns have various applications in manufacturing apparel, home textiles, etc.

Semi dull, partially oriented yarns have more strength and durability. The end-user applications of semi-dull partially oriented yarns are in the garment and apparel industries for weaving and embroidery works. These semi-dull yarns are available in various deniers and filaments.

What kind of product is made from Polyester Staple Fiber (PSF)?

1. Soften product

PSF Yarn is used in Non-Woven carpets, wadding, and filtration industries as a poly-fill for stuffing cushions, pillows, soft toys, quilts, etc.
