Learning outcomes |
At the end of the course, the student should be able to:
1) Gather skills at the level of fundamental concepts of different spinning processes, such as: count number, blending, doubling, drafting, twisting, and respective calculation;
2) Identify and differentiate short fiber and long fiber spinning processes in terms of operation flow and used equipment;
3) Plan the production process depending upon the main characteristics of the intended yarn;
4) Characterize the produced yarns in terms of structure and properties. Practical use of apprehended concepts in spinning quality control.
5) Explore new technologies, particularly CAD systems for the simulation, development and optimization of yarn production.
6) Learn some techniques in terms of markets and yarn selling.
7) Manage and plan the production of a spinning company.

Teaching Methodologies and Assessment Criteria |
Presentation, through face-to-face sessions and with the participation of students, of the theoretical, theoretical- practical and practical contents related to the concepts and techniques described in the syllabus.
Applied technical study of several linear textile structures. Applied examples, developed by students, in cooperative learning, based on real situations in the spinning industry.
Practical exercises in yarn development using digital techniques with individual and group practical exercises. Conducting successful case research in the industry and/or market of the spinning industry.
Autonomous study and preparation of deliverables: report and project for the development of a yarn.
The classification of the UC is obtained by an exam and by the evaluation of practical rep+orts. Final grade is given through the formula:
FINAL NOTE = 0.65 x T + 0.35 x P.
Subtitle:
T = Theoretical component grade
P = Practical component grade
