Course content
Lectures: 1. Computer-aided textile design systems, approaches to modeling, designing textile structures in line - fiber - yarn - flat textile (woven fabric, knitted fabric). 2. Basic quantities and relations describing fibers. Effect of fineness and density of fibers on the geometric parameters of the linear textile. Effect of twist on the geometrical and mechanical properties of the fiber bundle (yarn). 3. Single and ply yarn. Designing structural parameters and mechanical - physical properties of ply yarn. Experimental methods of measuring selected structural parameters of ply yarn. 4. Prediction of the mechanical properties of linear textiles. Tensile stress, tenacity and elongation of yarn (Solovev, Neckar, Pan, regression model of Uster statistics). Yarn bending rigidity (regression model, continuum mechanics). 5. Designing the properties of blended linear textiles. Influence of blending ratio of fibers on the geometrical and mechanical properties of linear textiles (number of fibers in the yarn cross-section, packing density, diameter, strength, ductility). Critical blending ratio and optimization of blending ratio. Experimental methods of measuring selected structural parameters of blended yarn. 6. General rule of structures of textiles (flat and spatial structure of woven and knitted fabrics) in relation to their properties. Formulation of crucial parameters affecting the properties of flat textiles intended for apparel and technical applications. 7. Definition of structural elements of pores in interlacing, Brierley's theory of tight woven fabric for determining the sett of woven fabric. 8. The geometry of the fabric, the classification of interlacing by Novikov, waved threads in the fabric, modeling thread interlacing in the fabric - a mathematical expression of binding wave for the definition of shortening of threads in the fabric. 9.-10. Uniaxial and biaxial stress of woven and knitted fabrics. Modeling mechanical properties of woven fabrics (strength, ductility) in plain and non-plain interlacing. 11. -12. Prediction of selected utility properties - surface covering, porosity, thickness, roughness, permeability of woven fabrics, etc. Mathematical modeling and experimental methods for the evaluation of utility properties of fabrics. 13. Designing properties of warp single jersey with complementary threads (called laying-in structures) with respect to the used materials and utilization. Effect of strength and dimensional stability, the benefits of warp knitted fabrics. 14. Design and modeling of warp knitted double faced knitted fabric and impact of its geometrical parameters on the design of prediction of mechanical and physical properties. Practice: Project form of practices: Modeling properties of textile structures in modules: linear textile assemblies (yarns) - - flat formations (woven fabric, knitted fabric), the use of selected models for the design, creation of simple algorithms, linking results from individual modules, based on a combination of mathematical modeling and experimental research.

Learning outcomes
The aim of the course is to introduce students to ways of designing textile structures in modules - fibers - yarn - flat textile (woven, knitted fabric). Students are acquainted with the current computer aided textile design systems including software LibTex and ProTkaTex developed at FT TUL. There are analyzed utilization of mathematical, physical and regression models for the prediction of selected mechanical and utility properties of linear and flat textiles. There are mentioned the assumptions for equations validity, sensitivity to input parameters and their reproducibility and variability of the results is discussed in relation to experimental data.
Student will obtain knowledge of textile construction and design, creation and verification of models.
