The purpose of dyeing is to give a fabric a precise colour, most often different from its natural colour (or white colour) by means of dyes. 

At Crouvezier Développement, we work with several types of dyes: 

 – Reactive dyes : 

Offers a very rich range of shades. These dyes have excellent wash-fastness and chemical agents fastness properties (except for chlorine). They are used for dyeing cellulosic materials such as cotton, linen or viscose.  

– Vat dyes : 

These dyes are very resistant to washing, light, rubbing, perspiration and chemical agents (even chlorine). They are used for dyeing cellulosic materials such as cotton, linen or viscose. 

– Direct dyes : 

These dyes have good light fastness. They are mainly used for dyeing light colours. 

– Disperse dyes : 

They are insoluble in water but can be dispersed using appropriate products. They are used for dyeing polyester. 

– Pigment dyes : 

These are small coloured particles insoluble in water, which are incorporated into resins that are applied to the fibre. They are used for artificial and synthetic fibres. However, the resulting dyes are rub-sensitive.
