High-performance fibres for composites, sportswear and protection

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.
