Polyester

Overview

Polyester is a synthetic, manufactured fibre derived from petrochemicals. The fibre is produced as a filament but can be cut into a staple to be spun

It is the world's most commonly used fibre, primarily due to the low cost of production and perceived ease of care.

Some polyester textiles are starting to be made from recycled polyester, rPET, frequently from the melting down and spinning of plastic bottles.

Polyester textiles shed plastic microfibres throughout their use and wash, which is contributing to a buildup of microplastics in the environment.

Context of Use

Polyester is frequently used in clothing such as t-shirts, jumpers/hoodies, skirts and dresses across all seasons, it's often used in fast fashion as it is relatively inexpensive to produce.

Polyester is commonly blended with other fibres (such as cotton) to create textiles that have favourable properties from both fibres. Favourable properties of polyester include 'wash and wear' meaning it's less likely to wrinkle in the wash and need ironing, strength and resistance to wear/abrasions, and elasticity. It can be used to make textiles that are 100% polyester.

Polyester is used in a range of homewares including upholstered furniture, bath towels, sheets, curtains and floor coverings.

Polyester is frequently used in sportswear due to its elasticity and ability to recover from being stretched. Although polyester is hydrophobic (it resists water) meaning it normally wouldn't wick moisture away from the skin, some brands/fabrics of polyester have been engineered to have a cooling effect

Care Guide

The following is a general guide to caring for this textile, however you should always refer to and follow the instructions on the care label of each garment.

How to Wash

Polyester can be machine washed or hand washed. Wash like colours together.

Washing Temperature

Polyester can be washed warm (40C) or cold. Using cold water will reduce your energy consumption.

Detergents and Bleach

Most laundry detergents are suitable for polyester, consider using one that has a low environmental impact

Bleach should be avoided when removing stains from polyester as it can damage the fibres. If bleach must be used consider using a non-chlorine based bleach.

Drying

Polyester is well suited to line drying, it will dry quickly and with few wrinkles. If you must tumble dry use the coolest setting possible on the machine.

Ironing

Polyester rarely requires ironing. If it must be ironed use the coolest or synthetic setting on the iron.

Storing

Polyester should be stored in a well ventilated area away from direct light

Recycle

100% polyester can be recycled. Currently some clothing stores offer take back schemes, however the practice is very limited.

Technologies are emerging to recycle polyester that has been blended with natural fibres. At present, access to these technologies isn't readily available for the public.
