Washdolly Science

 

 

Washdolly is a micro fibre cloth made of two synthetic polymers: 75% polyester and 25% polyamide. Polyester likes to bind to fat, which is why the cloth works well to wipe away grease and dirt without using chemicals. The clever production technique increases the surface area of the long, tiny fibres. Polyester and polyamide are arranged as alternating wedges (see microscopic photo) that are split up by high-pressure jets which create many extremely fine fibres. When water is applied to the cloth, it is stored between the pores of the fibre rather than binding directly to them. The result is a much faster drying fabric. Microfibres are able to attach themselves to the tiniest microscopic dirt particles because of a microscopic adhesive force between micro fibres and dirt known as van derr Waals force. Van derr Waals was a Dutch chemist (1827-1923) who won the Nobel Prize for discovering this force, which explains why geckos can walk on walls and ceilings - they use the tiny hairs on the bottoms of their toes.

Result: This sticky force attracts dirt and grease with millions of micro fibres in this highly porous material with a large surface area that fits in the palm of your hand, removes your makeup with ease while cleaning your face, grips boogies and is gentle on skin.
