Subject fundamentals
This course aims to provide an overview on fibers applied in engineering, describes their properties and application. The course first provides basic ideas on the preparation, the structures and the properties of polymers from which fibers are obtained, then describes a selection of characterization techniques, finally discusses the main processing technologies (from spinning methods to obtain fibers to finishing processes). Applications in different fields will be discussed, including textiles, structural composites for mechanics and aerospace, non conventional fields (such as biomedical devices and flexible electronics).
Basics on the scientific literature and on the bigliographic search are also presented.
Expected learning outcomes
By completing this course the student will know the composition and the structure of fibers, their relationship with properties, the main applications and processing methods. By examining the scientific literature and by doing assignments, students will acquire abilities in data acquisition, their critical discussion, communication and problem solving skills.
Prerequisites / Assumed knowledge
Students should know the basic concepts of general chemistry and material science.
Contents
Fibers, microfibers, nanofibers: geometrical characteristics, structures, physico-chemical properties.
Basics on 1) synthesis and structure of polymers for fibers 2) polymer morphologies and properties 3) some techniques for the physico-chemical characterization of fibers (mainly fibers for textile)
Fibres:
Natural fibers (animal fibers i.e. wool, silk; cellulosic fibers i.e. cotton, hemp, linen): chemical structures, morphologies, properties, processes
Man-made fibers (nylon, polyesters, acrylics, polyolefins, elastomers): chemical structures, morphologies, properties, some industrial synthetic processes
Special fibers (aramids, carbon fibers, carbon nanotubes): chemical structures, properties, syntheses)
Spinning processes: wet spinning, dry spinning, melt spinning, and gel spinning, electrospinning
Finishing processes: surface modification of fibers, sizing. Basics on dying processes.
Applications of fibers for: textiles, innovative textiles (geotextile, medical textile, textile for automotive), composites, smart materials (adaptive and responsive fibers, flexible electronics)
Delivery modes
Weekly lectures and seminars; 6-7 assignments in which students apply concepts learned in lectures and solve problems; each student will choose a topic and make a two-page report on it searching data in the scientific literature. A visit to a textile plant is scheduled.
Texts, readings, handouts and other learning resources
Handouts will be available.
Most of the readings on organic chemistry are from this textbook:
Kaplan, N.S. A Practical Guide to Fibre Science Abhisek Publications 2009 (e-book available at the Politecnico Central Library)
Several topics of the course are found in the following books available at Politecnico Libraries:
Mattila H. Intelligent textile and clothing Woodhead Pub. 2006
Hu, J.Adaptive and Functional Polymers, Textiles and Their Applications World Scientific & Imperial College Press 2011
Pan N. Functional Textiles for improved performances, protection, health Woodhead Pub. 2011
Assessment and grading criteria
The grade is determined by a written test assessing the knowledge of the topics (45 min, closed-book, closed-notes examination, 7-8 questions, 2 problems), by the evaluation of the assignments and by grading the report. The grade is the weight average of the different marks (50% for the written test, 20% for the assignments, 30% for the report)
