Microfibre

Quick answer

Synthetic fibre finer than 1 denier (thinner than silk). Usually polyester/polyamide blend. Absorbs rapidly, dries fast.

Microfibre (or microfiber) is synthetic fibre with diameter less than one denier - finer than silk, invisible to the naked eye. Most microfibre towels use a polyester/polyamide (nylon) blend.

How It Works

The ultra-fine fibres create massive surface area relative to weight. When split (wedge-shaped), surface area increases further. This surface area:

  • Traps and holds water between fibres
  • Creates capillary action for absorption
  • Grabs particles (why microfibre is used for cleaning)

Unlike cotton, microfibre doesn't absorb water into the fibre - it holds water between fibres through surface tension.

Properties

Advantages: - Extremely quick drying - Lightweight and packable - High absorbency for weight - Low friction (good for hair towels) - Sand releases easily

Disadvantages: - Synthetic feel some dislike - Can feel "grabby" on skin - May hold odours if not washed properly - Sheds microplastics when washed - Not biodegradable

Quality Varies

Microfibre quality depends on: - Fineness: Finer = better performance - Blend ratio: Higher polyamide often means softer - Split vs unsplit: Split fibres absorb better - GSM: 300-400 typical for towels

Cheap microfibre may be coarse and less effective.
