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.
