Polymer science.
Polymer science.
Definition and scope of technical textiles. Milestones in the development of technical textiles. Market overview: worldwide consumption of technical textiles by product type and by application. Mechanical properties of textiles: definition of linear density, tensile strength, tenacity, elongation, yield points, modulus, elastic recovery. (6 hours) High performance fibres (20 hours) - Meta-aramid fibers: structure, polymerization, spinning, post-spinning processes, properties, applications for heat and flame protection. - Liquid crystal polymers: lyotropic and thermotropic liquid crystals. Dry-jet wet spinning of high-strength fibres. Para-aramids. Liquid crystal heterocyclic fibres (PBO Zylon, PBT). Liquid crystals aromatic copolyester (Vectran). Applications of para-aramids and other liquid crystal polymers in the field of ballistic protection. - High strength- high modulus polyethylene (Dyneema). Gel spinning. Superdrawing. - Carbon fibres: Application of carbon fibres in composites manufacturing. - Glass fibres: Time-temperature transformation curves. Fibre glass compositions. Optical fibres. Composite: use of fibres in composites, mechanical properties of composites, effect of yarn interlacing on composites properties. Heat and flame protection: inherently flame retardant fibres (Basofil, Kynol, arimid, modacrylics), chemically modified fibres (intumescent systems, FR finishing of cotton, viscose, wool). Textiles for sportswear: introduction to thermo-physiological comfort. Effect of environment, metabolism and clothing on thermal comfort. Criteria for designing high-performance sportswear: wicking properties and liquid management of fabrics, water vapour permeability, air permeability, thermal resistance. Models for predicting comfort: Fanger model and predictive mean vote. Heat and mass balance across the human body (20 hours). Smart textiles (14 hours): stimuli-responsive polymers for smart textiles, phase-change materials, shape-memory materials. Wearable technologies: electronic textiles, conductive polymers, screen printing technique. Use of smart and wearable technologies to improve safety and performance at work and during sports activities.

The course will be made of lectures (48 hours) and work groups (12 hours) during which the students will focus on specific applications of high performance fibres (for instance, agrotextiles) and will deliver a presentation to the class-mates at the end of the course.

Modalità di esame: Prova scritta (in aula); Elaborato progettuale in gruppo;
Exam: Written test; Group project;
The assessment will be made of a written examination (1.5 hours) composed of 3 open-questions on the course topics. No consultation of books and notes is possible during the written examination. Maximum grade of the written exam 24/30. The remaining 6 points will be obtained by the assessment of the team-work presentation. The oral examination will consist in the development of a specific topic assigned to each team. Every student will present in English a part of the team work, using a ppt presentation. Among possible themes, the analysis of the 12 categories of technical textiles or advanced sportswear for specific sports.
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
Modalità di esame: Prova scritta su carta con videosorveglianza dei docenti; Elaborato progettuale in gruppo;
The exam will be an individual online oral assessment (24/30 maximum grade) plus an online team work presentation (6 points max), which will be discussed by the team members during the scheduled lectures.
