Apparatus and method for carrying out optical readings on textile materials submitted to dyeing

A method for carrying out optical readings on textile materials submitted to dyeing, the method comprising the steps of:

• providing a first optical reading chamber into which a dyeing bath flows, said dyeing bath being drawn out of a dyeing tank or machine carrying out a dyeing process on a given textile material;
• providing a sample made of the same material of which said textile material is made and positioning said sample in said first optical reading chamber;
• providing a second optical reading chamber into which a dyeing bath coming from said dyeing tank or machine flows;
• executing a reflectance optical reading inside said first chamber and a transmittance optical reading inside the second chamber and transmitting the signals respectively corresponding to the light reflected by the specimen surface in the first chamber and/or corresponding to the light transmitted through the fluid contained in said second chamber, said signals being transmitted to an optical processing means.
