How Polyester Fabric Is Made

Polyester Fabric is a popular synthetic material that can be used in clothing, upholstery, and other products. While it is not as soft and supple as cotton or silk, it is durable, inexpensive, and easy to work with. It also resists fading from sun exposure and is mildew-resistant. It is also wrinkle-free and hypoallergenic, making it a good choice for garments that will be regularly washed. Polyester is also available in a wide range of colors and textures.

Unlike natural fibers, which are harvested from living plants, polyester is created by chemically combining petroleum-derived ethylene with dimethyl terephthalate. The resulting polymer is then spun into thread or yarn to form the fabrics that are used in everyday clothing, draperies, and furniture covers.

Ethylene polyester (commonly known as PET) is the most common type of polyester, and it accounts for about 90% of all polyester made. To produce it, ethylene is reacted with dimethyl terephthalate in a high-heat reaction chamber. The resulting polymer chips are then melted and extruded through spinnerets, which have tiny holes. The shape and quality of these holes can be changed to create different kinds of fibers, and the resulting threads are twisted together into yarn. This process is known as melt spinning.

In addition to the basic woven polyester that is used in apparel, there are many other types of fabrics made from it, including taffeta, satin, velvet, and corduroy. In some cases, the polyester is used as a substitute for cellulose in natural fabrics, such as cotton. This makes the garments much cheaper, but it also affects how soft and supple the fabric is.

There are even plant-based forms of polyester that use ethylene sourced from sugar cane or other plants. These kinds of plant-based fabrics are less environmentally harmful than those made from fossil fuels, which require large amounts of energy to create and refine.

Once the polyester is woven into fabric, it can be dyed in a variety of shades and patterns. Some are designed to mimic the look of other materials, such as silk or suede. Others are designed to be more functional, such as in waterproof outdoor clothing and gear, or for medical and industrial applications.

It is impossible to find modern consumer apparel that does not contain some kind of polyester. Despite its negative environmental impacts, it is one of the most versatile and inexpensive fabrics in the world. Because it is highly resilient, it can withstand heavy use and still be washed and worn many times over. It can also withstand extreme heat without melting or burning, whereas most natural fibers will char. However, it does not degrade naturally in the environment and may take centuries to break down completely. This is a major reason why it is important to dispose of polyester clothing properly and recycle as much of it as possible.
