Polyester fiber is one of the most widely used synthetic fabrics in clothing and other products. It is made from purified terephthalic acid (PTA) and monoethylene glycol (MEG) through a process called polycondensation. This process polymerizes the raw materials into polyester polymers which are then spun or drawn into long chains called polyester fibers.

Properties and Uses of Polyester

Some key properties of polyester fibers that have led to its widespread use include:

Durability: Polyester Fiber are very durable and resistant to abrasion, wrinkles, and shrinking. Garments made from polyester maintain their shape and do not require ironing. This makes them suitable for activewear.

Low Maintenance: Polyester fabrics are easy to wash and dry. They retain their properties even after multiple washes and do not require special care. This simplifies garment maintenance.

Shape Retention: As mentioned earlier, polyester fabrics resist wrinkles very well. They retain their shape and drape even after being crumpled or folded for long periods. This is useful for dress fabrics, home furnishings etc.

Drying Performance: Polyester fabrics dry very quickly as water tends to bead up on the fiber surface rather than getting absorbed. This makes polyester a preferred choice for swimsuits, sportswear and activewear.

Variety of Properties: Depending on how it is spun and fabricated, polyester can mimic the properties of other natural fabrics like cotton, silk, wool etc. It is suitable for diverse applications like clothing, home furnishings, industrial fabrics.

Types of Polyester Fabrics

The basic polyester fiber can be processed into different constructions to produce various polyester fabrics with unique properties:

Plain Polyester: This is the basic polyester yarn or fiber woven or knitted into plain fabrics without additional finishes or processes. Used in t-shirts, dresses, quilts, etc.

Microfiber Polyester: Thinner polyester fibers less than 1 denier in size that create ultra-soft and lightweight fabrics. Used in delicate fabrics, dry-fit garments, filtration.

Fleece Fabric: Polyester staple fibers are needlepunched to form lightweight insulating fabrics without weaving or knitting. Used in jackets, activewear.

Velvet Polyester: Cut loop pile yarns create a plush surface. Used for drapes, upholstery, evening wear accents.

Gabardine Polyester: A tightly woven durable twill weave fabric suitable for blazers, trousers.

Double Knit Polyester: A stretchy knit fabric produced on a double knitting machine. Used in swimwear, leggings, shaping garments.

Satin Polyester: A smooth, lustrous fabric made from highly twisted polyester yarns. Used in evening and bridal wear, wall coverings.

Eco-Friendly Polyester Production

While polyester production uses petroleum-based resources, manufacturers are undertaking efforts to adopt eco-friendly practices:

Use of Recycled Polyester: Post-consumer polyester waste is collected, cleaned and reprocessed into recycled polyester fibers and fabrics. Brands are increasing use of recycled polyester in garments and products.

Adoption of Renewable Resources: Research is ongoing into using bio-based raw materials like plant-based MEG to partially replace petrol-based MEG in polyester production. This helps reduce dependence on non-renewable resources.

Reduction of Water Use: Newer production techniques aim to reuse and recycle water in polyester manufacturing as much as possible to minimize fresh water intake.

Lowering of Carbon Emissions: Switching to cleaner energy sources for polyester manufacturing and optimizing reactor efficiencies can help lower greenhouse gas emissions from the process.

While polyester will likely continue being a plastics-based fabric, the textile industry is working on new production methods and materials to make it more sustainable for the future.

Due to its durability, long-lasting qualities, low maintenance needs and wide range of properties, polyester fiber has become the most widely used man-made fiber globally. From clothing to home furnishings to industrial applications, polyester continues dominating various markets. Improvements in production techniques also aim to reduce polyester’s environmental footprint over time. As long as petroleum byproducts exist, polyester is set to stay as a top synthetic fabric choice.
