Learning outcomes |
The UC allows us to understand the chemistry of textile fibers, chemical processing and its effect on fibers. The student will be able to understand: the chemical and molecular structure of polymers and fibers, the behavior of different chemical agents, control parameters, and chemical pre-treatments. Thus, students should
1 Know the chemical and molecular structure, chemical composition and functional groups involved in the reactivity of textile fibers.
2 Be able to apply the appropriate experimental techniques to analyze the chemical properties of different fibers, related to the quality of materials, in the different stages of textile processing: Control parameters.
3 Know and be able to carry out the different textile chemical pre-treatments.
4 Acquire knowledge regarding the chemical composition and chemical properties of the most used artificial and synthetic fibers, molecular stability and degradation.

Teaching Methodologies and Assessment Criteria |
The course is structured in theoretical and practical-laboratory classes. The teaching and learning methodology will be student-centered. The teacher, in theoretical classes, exposes the contents of the curricular unit and presents examples and applications for discussion, encouraging reflection and problem solving. The practical-laboratory classes will take place in the Textile Chemistry Laboratory, where the students can work with different machines/equipment and carry out various experimental works in the area of Textile Chemistry. Students must prepare, at the end of each experimental work, a written report in which they must apply the acquired knowledge and scientifically discuss the results obtained. The UC assessment consists of a written test (during the teaching-learning period) with a weight of 70%, and the continuous assessment of the laboratory component (including reports and discussion) with a weight of 30 %.
