Chemical Textile Technology Laboratory

Presentation

The Chemical Textile Technology Laboratory develops activities related with physical chemistry, optimization and control of chemical-textile industrial processes of preparation, dyeing and finishing with the aim to obtain fully integrated processes, both from industrial and environmental point of view.

Lines of research

• Physical-chemistry and dyeing kinetics.
• Reproduction of processes at laboratory and pilot plant scale
• Optimization of processes to minimize its environmental impact.
• Studies of application of new auxiliaries and products for preparation, dyeing and finishing operations.
• Enzymatic applications.
• Quality control of final product: colour fastness to standardized agents (according ISO 105), shrinkage, pilling, UV protection factor, permeability, surface properties.
• Colour measurement: chromatic coordinates, colour differences, degree of whiteness.

Equipment

• Reflection spectrophotometer.
• UV-Vis spectrophotometer.
• Fluorescence spectrophotometer.
• UV diffuse transmittance analyser.
• Appliances and tools to making dyes in a laboratory and in a pilot plant.
• Equipment for colour fastness testsaccording to ISO 105: Xenotest, Linitest, Fixotest, Crockmeter.
• Air and water permeability testers.
• Martindale abrasion tester.
• Contact angle analyser.
