Polyester

Quick answer

Synthetic fibre made from petroleum. Quick-drying, durable, but not absorbent. Used in microfibre and blends.

Polyester is a synthetic fibre made from petroleum-derived polymers. It's the world's most-produced fibre and appears in many textile applications, including towels.

Properties

Advantages: - Very quick drying - Durable and strong - Resists shrinking and stretching - Holds shape well - Affordable - Doesn't wrinkle easily

Disadvantages: - Not absorbent (hydrophobic) - Can feel synthetic - Holds odours - Not biodegradable - Petroleum-derived (environmental concern) - Sheds microplastics when washed

In Towels

Polyester appears in:

Microfibre towels: Blended with polyamide (usually 80/20 or 70/30 polyester/polyamide). The microfibre structure overcomes polyester's poor absorbency.

Cotton-polyester blends: Added to cotton for durability and faster drying. Common in institutional/hotel towels. Typical blend: 80/20 cotton/polyester.

Quick-dry towels: Polyester's hydrophobic nature aids fast drying.

Why Cotton-Poly Blends?

Adding polyester to cotton: - Increases durability (survives industrial washing) - Speeds drying time - Reduces cost - Sacrifices some absorbency

Hotels and institutions often prefer blends for laundry efficiency.

Environmental Concerns

Polyester: - Made from fossil fuels - Not biodegradable - Sheds microplastics during washing - Energy-intensive production

For eco-conscious buyers, natural fibres are preferred.
