What is Polyester Fabric?
How is Polyester Fabric Made?
Polyester is a synthetic fiber created from polymers that come from oil. Polyester fibers are produced through a series of intricate processes that amalgamate oil and chemical compounds. Unlike modal, polyester is built purely from synthetic fibers, making it cheaper.
Polyester retains a certain degree of unmatched quality and strength due to its man-made origin. It can be stitched into a range of fabrics, from heavy-duty, cold-weather jackets to light, breathable, activewear. This polymer is versatile, which also explains its demand in the textile industry.
Key Properties of Polyester
Polyester has a reputation for being one of the most durable materials, being water resistant, and, unlike most fabrics, it doesn’t retain moisture, making it ideal for activewear. Polyester retains a certain degree of warmth and has good insulating properties. When densely woven, it can retain a certain degree of warmth which makes it perfect for jackets and other cold-weather apparel. This is also one of the reasons why polyester is most often compared to modal.
Warmth Comparison: Is Modal Warmer Than Polyester?

Texture also affects comfort level. A lighter fabric like modal can feel cool and soft and airy, while polyester tends to feel heavier, warmer and more constricting.
Durability and Longevity
Of the two, polyester is more durable. It stretches, shrinks, and fades less even after multiple washes. This makes it more suitable for activewear, sports, and outerwear. It provides warmth over time and keeps its shape.
While modal fabric is strong, it is not as durable as polyester. It wears out faster particularly when washed too often. It does, however, hold the colour well and does not pill on garments.
Indirectly, modal’s lack of durability negatively affects its warmth retention. A worn out modal fabric has less structure, and thus less insulating capability, while polyester outperforms.
