Objectives

Background – For the competitiveness of the textile sector the concern is determinative/implementation of techniques that allow to make well (to dye, to print...) to the first one, for form to contribute for the increment of the quality with rigorous control of involved costs. The increasing search of quality conjugated with functional elements that allow them to differentiate of the conventional, sends to us for the domain of the technologies of would dyeing and print in its varied flowing.
Aims – to give a theoretical and pratical of dyeing processes, that they make possible its integration in a finishing section.

Program

Introduction of dyeing sector in the textile row.
Study of the colour. Studies of the equations and equipment used for evaluation of the colour.
Study of the relation of the color with the chemical constitution.
Classification of the dyestuff and its relation with the textile fibers.
Study of the main properties of fasteness and its relation with dyestuff and used fibers.
Study of the general theory of the dyeing.
Study of the direct, vat, reactive, sulphureous, dispersed, acid and cationic dyestuff.
Study of the dyeing processes of celullosic, polyester, polyamide, acrilic, wool fibers and the mixtures of polyester with celullosic.
Ambiental problems related to the dyeing process.
New technologies/process
