Polyester Fabric: A Comprehensive Guide

Polyester fabric, also known as polyethylene terephthalate (PET), is a versatile synthetic material that is widely used in various consumer and industrial applications. In this comprehensive guide, we’ll delve into the characteristics, production, uses, and environmental impact of polyester fabric. Let’s explore the world of polyester fabric together.

What is Polyester Fabric?

Polyester fabric is a type of synthetic textile that is derived from polymers primarily composed of compounds within the ester functional group. It is made from ethylene, which can be derived from petroleum or other sources. Polyester fabric is known for its durability and resistance to environmental conditions, making it suitable for a wide range of applications.

It is commonly blended with natural fibers like cotton to improve properties such as shrinkage, durability, and wrinkle resistance. However, the blend may reduce the comfortability of the fabric. Polyester is highly breathable and has excellent moisture-wicking abilities, making it ideal for activewear and outdoor apparel.

A Brief History of Polyester Fabric

The journey of polyester fabric began in 1926 when it was first synthesized as Terylene by W.H. Carothers in the UK. British scientists continued to develop better forms of ethylene fabric, catching the interest of American investors and innovators.

During World War II, polyester fiber gained popularity as a material for parachutes and other war materiel. After the war, polyester found a new consumer market in the postwar economic boom. Consumers were drawn to its improved durability compared to natural fibers.

However, in recent decades, concerns about the environmental impact of polyester have arisen. Nonetheless, polyester remains one of the most widely-produced fabrics globally, and it can be found in almost every type of consumer apparel.

How is Polyester Fabric Made?

It is primarily made from polyethylene terephthalate (PET), which is derived from ethylene glycol and dimethyl terephthalate. The production process involves several steps:

  1. Reacting ethylene glycol with dimethyl terephthalate at high heat to form a monomer.
  2. Reacting the monomer with dimethyl terephthalate again to create a polymer.
  3. Extruding the molten polyester polymer into long strips, which are cooled, dried, and broken into small pieces.
  4. Melting the small pieces to create a honey-like substance, which is then extruded through a spinneret to form fibers.
  5. Depending on the desired type of fibers, the polyester filaments may be cut or treated with various chemicals.
  6. The polyester fibers are spun into yarn and undergo post-production processes such as dyeing.

It can also be made from plant-based sources, where ethylene is derived from cane sugar instead of petroleum. This alternative provides a more environmentally-friendly option, although it may be less durable than petroleum-based polyester.

Types of Polyester Fabric

There are several types of polyester fabric, each with its own unique characteristics and applications. The three major types of polyester fabric include:

  1. Ethylene Polyester (PET): This is the most common type of polyester fabric and is often referred to as simply “polyester.” It is widely used in the textile industry and offers a good balance of durability and affordability.
  2. Plant-Based Polyester: Some polyester fabrics are made from plant-based sources such as cane sugar. These fabrics are biodegradable and offer a more sustainable alternative to petroleum-based polyester.
  3. PCDT Polyester: PCDT polyester is less common but is known for its elasticity and durability. It is often used in heavy-duty applications such as upholstery and curtains.

Each type of polyester fabric has its own advantages and uses, allowing for a wide range of applications in various industries.

Uses and Applications of Polyester Fabric

Polyester fabric is incredibly versatile and is used in numerous applications across different industries. It is commonly used in apparel, including shirts, pants, hoodies, dresses, jackets, underwear, socks, and more. The durability and resistance to environmental conditions make polyester fabric suitable for both casual and formal wear.

In addition to apparel, polyester is also used in home furnishings such as sheets, blankets, curtains, and upholstery. Its stain-resistant properties make it a popular choice for households with children or pets. Industrial applications of polyester include LCD displays, holographic film, boat materials, and tarps.

It is also widely used in the production of bottles, films, packaging materials, and even high-performance products like car tires. Its versatility and affordability contribute to its widespread use in various industries.

Environmental Impact of Polyester Fabric

While polyester fabric offers many benefits, it also has a significant environmental impact. The production of polyester involves the extraction and refinement of fossil fuels, which contribute to pollution and the depletion of limited resources. The manufacturing process releases harmful synthetic byproducts, and the dyes and treatment processes used in polyester production can contaminate the environment.

Furthermore, It is not biodegradable and can take centuries to degrade in the environment. Washing polyester fabrics can release microfibers into the water supply, which harms marine life and contaminates drinking water.

However, efforts are being made to develop plant-based polyester alternatives that are biodegradable and have a lower environmental impact. These alternatives offer hope for a more sustainable future for polyester fabric.

Certifications for Polyester Fabric

Polyester fabric may be eligible for various certifications, particularly recycled polyester. Certifications such as OEKO-TEX Standard 100 and the Global Recycle Standard (GRS) ensure the authenticity of recycled polyester. These certifications help consumers make more informed choices and promote sustainable practices in the textile industry.

It’s important to note that It is not eligible for organic certification due to the extensive chemical manufacturing processes involved, even for plant-based alternatives.


Polyester fabric is a widely-used and versatile material with various benefits and applications. Its durability, resistance to environmental conditions, and affordability make it a popular choice in the textile industry. However, it also has a significant environmental impact, prompting the exploration of more sustainable alternatives.

As consumers, it is crucial to consider the environmental impact of the fabrics we choose and support initiatives that promote sustainability in the textile industry. By making informed choices and supporting certifications for recycled polyester, we can contribute to a more sustainable future.

Remember, when choosing polyester fabric, opt for high-quality products and consider recycling or repurposing them when they reach the end of their lifecycle. Together, we can work towards a more sustainable and environmentally-friendly textile industry.
