Learning outcomes
Within this subject students obtain information about these areas: construction and design of woven fabrics, influence of input fabric parameters on fabric structure as well as on weaving process and final mechanical and end-use properties. Students obtain information about areal and spatial geometry of woven fabric, analysis internal position of individual threads in plain weave and other different interlacing, definition of float part in weave. Information and definition of waviness, threads crimp, definition of fabric geometry on the basis of transversal and longitudinal cross section.
Orientation in these fields: structure and fabric geometry, interlacing of threads and their fabric geometry definition, fabric structure versus fabric properties.
Prerequisites
Knowledge of weaving, yarns structure, mathematics.
