1. What is Polyester?
Definition and Origin of Polyester
Polyester is a polymer fibre synthesised using petrochemical derivatives, most commonly ethylene glycol and terephthalic acid. “Polyester” is a group of polymers bonded to each other by ester functional groups. Although the base fabric comes from petroleum, modern technology allows polyester to be made from recycled fibres, which makes it an increasingly popular sustainable fashion material.
Polyester first evolved in the early 1940s when the British chemists John Rex Whinfield and James Tennant Dickson synthesized polyethylene terephthalate (PET). It entered the marketplace in the 1950s, and quickly swept up the trend with its greater strength, affordability and convenience than natural fibres such as cotton and wool.
How Polyester is Manufactured
Polyester is manufactured in several major steps, primarily through a chemical process called polymerization. Here’s a simplified explanation:
Polymerization:
Ethylene glycol and terephthalic acid are heated and bonded under high pressure to create long chain polymers of polyethylene terephthalate (PET). This creates a melted plastic.
Extrusion:
The molten PET is pumped through spinnerets (tools with very small holes) to produce thin polyester filaments. These filaments are then cooled and frozen.
Drawing:
Polyester fibres that have hardened are stretched (or “drawn”) to increase their stiffness and stretch. This also squares the molecular shape of the fibers, making them more durable.
Spinning and Weaving:
The fibres pulled from the yarn are spun into yarn, and the yarn is then knitted or woven into cloth.
Key Properties of Polyester
Polyester is popular because of its outstanding properties, enabling it to be used for an extensive variety of applications:
Durability:
Polyester fibers are impervious to abrasion, tear and pilling, making them ideal for products that require durable features.
Wrinkle Resistance:
In contrast to natural fibers, polyester is soft and doesn’t wrinkle, which means it doesn’t require ironing.
Moisture-Wicking:
Polyester repels water because it’s hydrophobic. It has the ability to remove moisture from the body and make you feel dry and comfortable.
Lightweight:
Polyester, however durable, is also thin, making it ideal for clothing and industrial use.

3. Key Properties of Polyester Fabrics
The durability and popularity of polyester fabrics result from an encapsulated mix of features that make them adaptable to a variety of applications.
a. Moisture-Wicking and Quick-Drying
Polyester is naturally water repellent, meaning it repels instead of absorbs water. This feature allows polyester to keep moisture from your skin, which is ideal for sportswear, active wear, and outdoor clothing. If used while you do physical activity, polyester keeps you comfortable and dry by drawing sweat up to the surface of the fabric where it quickly evaporates.
Quick-Drying Advantage:
The quick-drying characteristics of polyester make it especially convenient for athletes, outdoors enthusiasts, and travellers. Polyester clothes and gear dry more rapidly than cotton or wool, even when they’ve been steamed, wet or washed. This feature helps to minimise downtime and make things easier, especially when you are out in the open and on the road where drying is of utmost importance.
Performance Applications:
The wicking properties of polyester are usually complemented with treatments or blended with other fibers to create high-performance sports and outdoor clothing.
b. Resistant to Shrinking and Stretching
Polyester is renowned for its high dimensional stability. Polyester, unlike natural fibers, doesn’t stretch or lose shape after washing or use. This strength against deformation stems from its synthetic polymer matrix, which confers innate stability and toughness.
Shrink-Resistant:
Polyester clothing and fabrics retain their size even after several washings and repeated heat treatments. This feature prevents garments from shrinking or stretching over time.
Stretch-Resistant:
Polyester is less stretchy than wool or cotton. This makes polyester a perfect fabric for fabrics in which the shape and structure of the fabric is important, including uniforms, upholstery, and industrial fabrics.
c. Wrinkle and Fade-Resistant
Polyester fabrics resist wrinkles and maintain a wrinkle-free finish without the use of ironing. It’s an easy-to-maintain property that’s a benefit for consumers and businesses alike.
Wrinkle Resistance:
Polyester is wrinkle resistant because the synthetic fibers don’t crease as much as natural fibers. It is one of the most commonly used fabrics for travel attire, uniforms, and home furniture that needs to stay clean.
Fade Resistance:
Polyester resists dye in an impressive way, allowing for rich hues that don’t fade from washing or sunlight. Which makes it an excellent material for outdoor gear, curtains, and upholstery that require stain resistance.
d. Lightweight and Breathable
Despite being sturdy and strong, polyester is lightweight, so it’s comfortable to wear and easy to work with. Textile technology has also enhanced the breathable qualities of polyester, making it appropriate for clothing that can be worn in the summer and used as sportswear.
Lightweight Fabric:
Polyester’s suppleness also makes garments and equipment lighter in weight, so it’s perfect for uses where weight is a major concern, including outdoor and travel wear.
