Learning outcomes Study different techniques and processes in the areas of finishing and printing of textile materials. Empower students with knowledge about the principles of textile finishing and printing, including products, machinery and processes. Identify and describe the different techniques and processes for finishing and printing textile materials.
Relate the properties of textile materials with finishing processes.
Apply CAD systems for engraving screen printing and rollers.
Select the most suitable printing processes depending on the textile and the wanted effect.
Perform experimental work that simulates industrial textile finishing and printing operations and discuss the results obtained.
Matching technologies to market demand.
Relate finishing and printing processes with environmental aspects and energy costs.
Syllabus General aspects of the finishing process on different textile materials. Chemical and mechanical finishes. Chemistry of crosslinkers. Detergents and detergency. Coatings.

Teaching Methodologies and Assessment Criteria The course is structured with theoretical classes and practical-laboratory classes. In the theoretical classes, theoretical and technological knowledge, associated with the syllabus of the curricular unit, is transmitted and examples are presented to illustrate the main functions of each application, encouraging discussion and problem solving. The practical-laboratory classes take place in the laboratories that support the functioning of the curricular unit, where the student will carry out various experimental works with practical application of theoretical and technological knowledge. At the end of each experimental work, students prepare a written report describing the processes applied and a reasoned discussion of the results obtained. The curricular unit assessment consists of a written test (during the teaching-learning period) with a weight of 50%, and the continuous assessment of the laboratory component (including reports and discussion) with a weight of 50 %.
Language Portuguese. Tutorial support is available in English.
