Mechanical and chemical finishing

The first step when the fabric leaves the loom is the pretreatment of the fabric. Crouvezier Développement specialises in the following pre-treatments: singeing, desizing, bleaching, washing.

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.

Singeing consists in burning off projecting fibres, without damaging the fabric, in order to obtain a smooth surface and minimise pilling. This technique is commonly used on natural fibre fabrics and synthetic and natural fibre blend fabrics.

The purpose of bleaching is to remove natural colouring matters with the production of a pure white material. Washing : This step consists of cleaning the fabric of any excess chemical residues from the previous steps.
