PET is the most common thermoplastic polymer in the polyester family. The first US commercial polyester fiber production was completed in 1953 by DuPont™ under the name Dacron®. It is the same polymer resin utilized in the plastic bottle industry. It is now the most widely used fiber, even surpassing cotton. Polyester is strong and resistant to shrinking, stretching, creasing, insects and most chemicals. The specific properties, however, vary significantly depending on the type of polyester fiber. Many are modified to increase flame, crush or oil resistance. The fiber cross section is often made into different shapes to change the feel and appearance of the fibers. It is often blended with wool, cotton, rayon, or flax. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less fire-resistant and can melt when ignited.


A manufactured fiber in which the fiber forming substance is any long-chain synthetic polymer composed of at least 85% by weight of an ester of a substituted aromatic carboxylic acid, including but not restricted to substituted terephthalic units, p(-R-O-CO- C6H4-CO-O-)x and parasubstituted hydroxy-benzoate units, p(-R-O-CO-C6H4-O-)x.

According to wikipedia, Polyester is a category of polymers that contain the ester functional group in their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. The material is used extensively in clothing.

Polyester Fiber Production

The most common polyester for fiber purposes is poly (ethylene terephthalate), or simply PET. This is also the polymer used for many soft drink bottles and it is becoming increasingly common to recycle them after use by remelting the PET and extruding it as fiber. This saves valuable petroleum raw materials, reduces energy consumption, and eliminates solid waste sent to landfills.

PET is made by reacting ethylene glycol with either terephthalic acid or its methyl ester in the presence of an antimony catalyst. The reaction is carried out at high temperature and vacuum to achieve the high molecular weights need to form useful fibers. PET is produced in a melt spun and drawing process. The three processes utilized in the production of PET fiber are polymerization, melt-spinning, and drawing or hot stretching the fibers based upon their elongation requirements.

Some Major Polyester Fiber Uses

Polyester fiber is used in production of various textile products, which are made of polyester fiber base. It gives the material stability, keeps textiles forms strength and is also well suited for matching with natural fibers.

Variation of polyester fiber products include over twenty different species with a width ranging from 0.11 to 1.7 tex and a length from 6 to 102 mm.

Polyester fibers are widely used in the production of cotton, linen, wool yarns and fabrics, as well as non-woven materials, warmth-keeping fabrics, floor coverings, fur fabrics, artificial leather and paper industries.

Polyester fibers meet the highest requirements of dynamicallyand rapidlydeveloping textile industry.

  • Apparel: Every form of clothing
  • Home Furnishings: Carpets, curtains, draperies, sheets and pillow cases, wall coverings, and upholstery
  • Other Uses: hoses, power belting, ropes and nets, thread, tire cord, auto upholstery, sails, floppy disk liners, and fiberfill for various products including pillows and furniture

General Polyester Fiber Care Tips

  • Most items made from polyester can be machine washed and dried. Use warm water and add a fabric softener to the final rinse cycle. Machine dry at a low temperature and remove articles as soon as the tumbling cycle is completed.
  • If ironing is desired, use a moderately warm iron.
  • Most items made from polyester can be dry-cleaned. (For specific instructions, refer to garment's sewn-in care label.)

Advantages of polyester

  • Our polyester fiber has many advantages over non-polyester materials.
  • It is available, relatively inexpensive, and easy to process through most types of non-woven machinery.
  • It’s extremely versatile. It ranges from very soft to very firm.
  • It’s more durable. Polyester absorbs less than one percent of moisture by weight, offers good dimensional stability under a variety of conditions, and has unique filling properties.
  • Polyester is easy to machine wash and dry clean. It has excellent memory characteristics to retain its shape, and unlike natural fibers, VNFIBER polyester is non-allergenic and doesn’t promote the growth of bacteria. What’s more, it’s recyclable – something everyone can embrace.
