Polyester

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.
