2 Students' perspectives from previous years A fantastic experience on so many levels. Would absolutely do it all over again. I miss the way from dormitory to student campus, walking on a road made of stone through forests, and the bridge and the exquisite buildings.

3 Topic 1 Topic 2 Topic 3 Topic 4 Topic 5 Influence of nozzle type on yarn quality in open end rotor spinning from the point of view of belt fibres analysis Gabriela Krupincová, Department of Structures and Technology The structure of open end spun yarn is characteristic by the occurrence of belt fibres on yarn surface. The effect of nozzle type as one of the most important parts of the openend rotor spinning system on yarn quality will be realized. The set of 100% cotton yarns spun under same condition and same level of Phrix twist coefficient 65ktex2/3m- 1 will be used as an experimental material. The number of belts fibres, length of belt fibres, and distance of their centres will be evaluated by using image analysis NIS Elements. Obtained results will be compared by the theoretical hypothesis and earlier studies of various authors (state of art). Application of phenomological nonlinear elastic mathematical models in modelling of selected woven min Petr Henyš, Department of Structures and Technology The aim of this project is to compare suitability of existing phenomological nonlinear elastic models (neo-hooken, Mooney-Rivlin, Yeoh, Ogden, Gasser ) for selected woven materials. The first step consists in experimental testing of selected materials. The second step consists in data treatment and model s parameters fitting in selected software (Matlab, Python ). Parametrical study of the tear resistance of selected woven min Lukáš Čapek, Department of Structures and Technology The aim of this project is to provide an idea about parameters influencing the tear resistance of selected woven. The parameters are: orientation of sample, morphology of fabric, stretch velocity and shape of initial crack. Consequently, the total energy needed for crack propagation will be compared.

4 Topic 6 Topic 7 Topic 8 Topic 9 Thermal properties of sports fabrics with dependency on structure parameters and maintenance Pavla Těšinová, Department of Textile Evaluation Clothing for sports is dependent on layering of garment and its individual thermal properties and on the set and air layer between which will be studied on commercial materials and computed by simple physical equations. Moisture management of knitted materials by various methods Pavla Těšinová, Department of Textile Evaluation Moisture management of knitted fabrics is complex problem and methods how to measure are more with different aspects. Topic is more concerned to compare techniques on defined laboratory prepared set of samples. Correlation between methods will be studied. Bending rigidity on multilayer materials Ludmila Fridrichová, Department of Textile Evaluation Bending rigidity of materials will be studied where lamination, bonding etc. were applied. This materials can be used for technical application and their bending parameters are important for example in car seats industry where cost is important same as quality. Preparation and Analysis of Aerogel Embedded Micro/Mesoporous membranes 2-3 months Mohanapriya Venkataraman, Department of Material Engineering The main aim of the study will be the selection of suitable polymer and preparation of micro/mesoporous active membrane with aerogel particles both in granular and powder form created in high voltage electrostatic field. The composition and physical properties (viscosity, surface tension, electrical conductivity) of dispersion will be optimized from point of view of spinnability and formation of nano structural arrangements (nanofibrous assembly, porous particular membranes, electronetted structures), process conditions of electrospinning (production rate, distance of electrodes, temperature, humidity and voltage) oriented to the preparation of selected nanostructural arrangements (nanofibrous assembly, porous particular membranes, electronetted structures). The preparation of membranes with tunable porosity created will be investigated and analyzed using different test methods.

5 Topic 10 Topic 11 Topic 12 Design and Fabrication of Thermal Instruments for Extreme Temperatures 2-3 months Mohanapriya Venkataraman, Department of Material Engineering The study will explore new experimental methods, design and fabricate new instruments to study the thermal properties of textile fabrics under extreme temperatures using different methods. Several techniques are available to determine the thermal conductivity of fabrics. The results from the new measurement techniques will be used for classification of materials and eventually for quality assessment of all type of insulation materials at extreme temperatures. Also, possibility of using the new equipment for selected thermal measurement experiments will be explore through comparison with measurements from similar methods.

The impact test parameters and textile reinforcement along with matrix, interphase effects, impact failure modes and major evaluation techniques for impact damage analyses will be explored. The focus of this work is to find the impact loading properties of different types of woven kevlar fabric structures before and after impregnation with resin. The analysis will be done at different impact times and different magnitude of forces. Total deformation, equivalent strain and equivalent stress created on these fabrics will be determined. By incorporating the interface of fabric and matrix, the impact resistance will also be predicted numerically. The simulated results will be validated with experimental data. A compatible resin/matrix system has to be selected along with the fabric in order to develop sufficient resistance to impact. The three-dimensional woven kevlar-epoxy composites will be used for effectively resistance to impact due to interface of fiber and matrix system. Incorporation of nanoparticulate fillers in the composite will be investigated. TECHNICAL UNIVERSITY OF LIBEREC Faculty of Textile Engineering Studentska 1402/ Liberec 1 5/7

Simulations will be conducted in 3-D fibrous geometries resembling the microstructure of a fibrous material. Assuming that the heat transfer through the interstitial fluid is independent of the geometrical parameters of the solid phase, resulting values will be used to predict the effective thermal conductivity of the whole media. Conductive, convective and radiative losses will be modeled. Textile structures with protective functions Textiles structures will be produced and evaluated with current knowledge on textile materials and clothing, and their use in the protection of humans in hostile environments. It will be evaluated under extreme conditions in a wide variety of industries. It will also be evaluated if they are suitable for health and safety workers in the defence, police and fire service. Novelties in 3D corrugated nonwovens Struto and Rotis techniques will be used to develop 3D corrugated nonwovens. These samples will be evaluated for various functional properties including thermal, acoustic and compression characteristics. The suitability in automotive and other industrial environment will be evaluated.
