Entry requirements NA
Mode of delivery Face-to-face
Learning outcomes Learn about materials and processes of textile technology Learn about the concept of fabric and the weave parameters Know the weaves of simple fabrics, colour effects and patterns Learn about the technical parameters of fabrics, their analysis methodology and influence on performance
The student should develop skills for recognize and know how to apply the textile materials, for recognize and analyze the production flows of textile chain and for understand the equipments operation. The student must have capacity to draw patterns of warp and weft fabrics, in simple fabrics, fundamental weaves and the derived from these; to analyze and identify structural parameters of fabrics and relate to the influence on performance

Teaching Methodologies and Assessment Criteria Teaching/learning activities fall in theoretical, theoretical-practical lectures and assignments. Teaching-learning methodology comprises exposure lectures by professor, is active and cooperative, encouraging reflection and focusing on student acquisition of concepts, the resolution of problems, the research and practical work. The pedagogical methodology, using audiovisual media, is made up by the presentation of theoretical contents and theoretical-practical practice. Students develop works with limitations previously imposed, in order to get to the heart of its individuality of expression. The works are presented orally and discussed in the class.

Evaluation of knowledge
- Written test - weight of 50%;
- Practical works - weight of 20%;
- Sintesis work - weight of 30%.

The attendance contributes to evaluation favouring the presence in classes.
Criteria: frequency - minimum 6 values;
approval, no examination needed - minimum 10 va
Language Portuguese. Tutorial support is available in English.
