Mercerised Merino

Mercerised Merino enhances the look and feel of wool fabric, whilst retaining all its natural advantages.

The mercerisation process for Merino wool is a chemical-based process normally applied to wool top or scoured loose wool which creates a ‘cashmere-like’ feel and a ‘silk-like’ appearance.

The technology


The mercerisation of wool involves the removal of the scale structure from the surface of the wool fibre which creates a smoother fibre surface, the effect of which is to increase the sheen. The second part of the process involves the application of a very fine layer of silicone polymer which is grafted permanently onto the fibres’ surface.

The application of the silicone polymer brings about significant improvement in the hand feel.

Although as a result of the treatment, the actual diameter (micron) of the fibre does not change, the perceived improvement in hand feel is the equivalent of using wool 2 - 3 microns finer.

The features

  • Improved hand-feel for worsted-spun and woollen-spun knitwear.
  • Brighter shades.
  • Machine-washable. 
  • More compatible for blending with noble fibres. 
  • Improved drape/fluidity. 
  • Improved comfort especially in next to skin products. 
  • Starting to become established in the area of coatings and accessories.
