Polyester Properties, Production, Price, Market and Uses


Polyester is world’s most commonly used polymer. This synthetic polymer is made from petroleum-derived ethylene glycol and terephthalic acid. They are either thermoplastics or thermoset based on their chemical composition and structure. Majorly used Polyester polymer is thermoplastics.


Polyester Thread

What is Polyester?

Polyester is a kind of polymer with some specific materials. It is often defined as a long chain of polymers with a composition of 85% ester with a dihydric alcohol and terephthalic acid. It is a type of Polyethylene terephthalate used for any fabric or textile and made using polyester yarns and fiber.

It primarily includes naturally occurring chemicals like cutin of plant cuticles and synthetics formed by step-growth polymerization such as polybutyrate. Usually, natural polyesters are biodegradable while most of the synthetic ones are not.

These materials are extensively used in the clothing industry. They are also used for manufacturing number of other products such as bottles, films, tarpaulin, canoes, liquid crystal display, film insulation for insulating tapes and many others.


Majorly these materials can be classified into two broad categories which are:

  • Saturated Polyesters- These are those type which has saturated form of backbones. Thus, they are not as reactive as the unsaturated polyesters are. They usually have low molecular liquids and are used as plasticizers or reactants.
  • Unsaturated Polyesters- These are kind of materials which have their backbones of alkyl thermosetting resins characterized by vinyl Unsaturation. They are usually used for reinforced plastics. These are the most commonly used and economical family of resins.

History of Polyesters

It was first invented by British Chemist John Rex Whinfield and James Tennant Dickson. It became popular in 1970 when it was advertised as a kind of miracle fiber which was worn for 68 days and was still presentable without ironing.

Soon it became a cheap and easily available form of fabric. Nowadays this polyester fabric is being extensively used for clothing, furnishing, textiles and more.

Characteristics of Polyester

These materials inhibit following basic properties:

  • They are durable and resistant to many chemicals.
  • They also provide strong resistance against abrasion, wrinkle and stretching or shrinking.
  • It can easily retain its shape and hence is good for making outdoor clothes for harsh climates.
  • Resins are lightweight and extremely strong in nature.
  • They can be easily washed and dried.

Physical Properties

Tenacity- (5-7 gm/den) Polyester filaments and staple fibers are strong because of their crystalline nature and this nature permits formation of highly effective Vander Wall’s forces. The fiber inhibits good tenacity due to the hydrogen bonds and this tenacity remains unchanged even if it is wet.

Elastic-Plastic Nature- It has good elasticity. The crystalline nature of fiber prevents wrinkle and crease.

Hydrophobic Nature- These materials are hydrophobic in nature and dry quickly. This is due to the polarity and the very crystalline nature of resins which resist entry of water molecules.

Thermal Properties

The melting point is 250°C and is a poor conductor of heat with low resistance towards heat. It can easily melt on heating. As it is a thermoplastic fiber thus, is capable of being shaped or turned when heated.

Chemical Properties

Acids & Alkalis – They are resistant towards acids in cold conditions but degrades by H2S04 in high temperature.

Alkaline conditions are seen in laundering hydrolyze the ester group of the polymer. The crystalline nature prevents from hydrolysis to a great extent and usually, it is the surface which gets hydrolyzed.

Bleaches- It does not require bleaching and can easily retain its whiteness. If necessary chlorine bleaches are used.

Sunlight & Micro-organisms- It can withstand sun’s UV rays and is highly resistant to acidic pollutants present in the atmosphere. It is also resistant towards bacteria and other micro-organisms.

Color Fastness- It is difficult for dye molecules to penetrate in the fiber during the dying process. It retains its color after regular wash.

Solvent- Solvents for polyesters are Chlorinated Hydrocarbon, F3COOH, and Phenol (in hot conditions).

Production Process of Polyester

How is Polyester made?

It is made up of long chains of polymers. Today the two major kinds of materials produced are Polyethylene terephthalate (PET) and poly-1, 4-cyclohexylene dimethylene (PCDT). PET is used on a wider range as it stronger than PCDT. However, in terms of elasticity and resilience, PCDT has more consumer uses.

These pellets or chips are synthesized from petroleum-based products. The process of synthesis is carried out using a chemical reaction which involves coal, petroleum, air, and water. These resins are made up of purified terephthalic acid (PTS) or dimethyl terephthalate (DMT)

The most common type of chemical reaction used to make these plastic materials occur at very high temperatures in vacuum. Usually, a petroleum by-product (alcohol) and carboxyl acids are mixed to produce a compound monomer or “ester” This reaction process is known as polymerization.

The polymer material created in the process of polymerization is further extruded into long fibers that are stretched for some time (Approximately 5 minutes) to gain original length.

How is Polyester Fiber Made?

These materials are produced in a very different and fascinating way. It is primarily an artificial man-made fiber.  These polymers are manufactured from petroleum from which the constituent acids and alcohols are derived.

Three basic steps involved in the synthesis of polyester are:

  • Condensation Polymerization- In this step acid and alcohol are reacted in a vacuum at very high temperatures. Once the process of polymerization has occurred the material is extruded to a casting in form of a ribbon. As it cools down the ribbon hardens and is cut into chips.
  • Melt-spun fiber- Further, in this step chips are dried completely, then the hopper reservoirs are used to melt these chips.As it is a melt-spun fiber, chips are heated, extruded through the spinnerets and cools upon hitting the air. Finally, it is loosely wound around cylinders.
  • Drawing– The resultant formed fibers are stretched to about five times their original length. This helps in reducing the width. As now the resin is ready in fiber form, it can be as filaments or can also be crimped and cut into staple lengths as per requirement.

Recycling of Polyester

These materials are made from petroleum, a non-renewable source of energy that means the environment is damaged during its extraction. It is not very hazardous as it is being recycled on a very large scale.

It is commonly recycled in form of textile material using clear plastic water bottles or the PET as a prime source of raw material. The recycling process involves following steps:

  • The collected PET bottles are sterilized, dried and then crushed into small chips.
  • Further, these chips are heated and made to pass through a spinneret from strings of yarn.
  • Then the yard is wound up in form of spools.
  • After this fiber is made to pass through a crimping machine to get a fluffy wooly texture
  • Lastly, the yarn is baled, dyed and knitted into polyester fabric.

In this recycling process, the most common form of textile made using recycled material is fleece which is a knitted pile fabric often, being used by outdoor clothing companies to primarily manufacture jackets.
