Theme: Relations between stress-stra<strong>in</strong> curves <strong>of</strong> <strong>in</strong>dividual fibers and s<strong>in</strong>gle staple yarnsSupervisor: pr<strong>of</strong>. Ing. Bohuslav Neckář, DrSc.Contact email <strong>for</strong> more <strong>in</strong><strong>for</strong>mation: bohuslav.neckar@tul.czThe pr<strong>in</strong>ciple aim <strong>of</strong> this work is a deeper understand<strong>in</strong>g <strong>of</strong> some processes determ<strong>in</strong><strong>in</strong>g <strong>in</strong>ternal mechanics<strong>of</strong> yarn, its tenacity and break<strong>in</strong>g stra<strong>in</strong>. It is observed that 1) mean stress-stra<strong>in</strong> curve <strong>of</strong> fibers showsusually higher stress-values then mean stress-stra<strong>in</strong> curve <strong>of</strong> yarn, and 2) the break<strong>in</strong>g po<strong>in</strong>t on stress-stra<strong>in</strong>curve <strong>of</strong> a yarn lies usually by other (smaller) value <strong>of</strong> break<strong>in</strong>g stra<strong>in</strong> <strong>in</strong> relation to correspond<strong>in</strong>g fibers. So,the fiber tenacity utilization is a common effect <strong>of</strong> both <strong>of</strong> these processes. The work <strong>in</strong> this field shall beconcentrated to:a) Experimental <strong>study</strong> <strong>of</strong> stress-stra<strong>in</strong> curves <strong>of</strong> fibers and yarns. We th<strong>in</strong>k about cotton sp<strong>in</strong>n<strong>in</strong>g, i.e.cotton type <strong>of</strong> fibers (chemical above all), and r<strong>in</strong>g- and OE-technologies.b) Theoretical analysis <strong>of</strong> experimental results based on mathematical model<strong>in</strong>g <strong>of</strong> significantphenomena (fiber slope <strong>in</strong> yarn body – generalization <strong>of</strong> Gegauff’s idea, variability <strong>of</strong> fiber crimp –idea <strong>of</strong> Neckář and Das, etc.) determ<strong>in</strong><strong>in</strong>g differences between mentioned stress-stra<strong>in</strong> curves.c) Theoretical analysis <strong>of</strong> yarn breaks <strong>in</strong> relation to fiber breaks. Mathematical (stochastic) model<strong>in</strong>g <strong>of</strong>destruction processes <strong>in</strong> yarns (variability <strong>of</strong> fiber properties – idea <strong>of</strong> Neckář and Das, <strong>in</strong>fluence <strong>of</strong>gauge length – ideas <strong>of</strong> Peirce, Neckář and Das, etc.)Theme: Relations between woven fabric structure and geometrical roughness <strong>of</strong> woven fabricSupervisor: Ing.

Some special protective garments like anti-ballistic vests do not support the water and vapour transfer <strong>in</strong> thethickness direction. There<strong>for</strong>e, moisture must be evaporated from the edges <strong>of</strong> the used cloth<strong>in</strong>g pieces.Un<strong>for</strong>tunately, standard methods do not make possible to measure and <strong>in</strong>vestigate the <strong>in</strong>-plane moisturetransfer <strong>in</strong> fabrics. In the <strong>study</strong>, a new experimental method will be used, which enables the determ<strong>in</strong>ation <strong>of</strong>this unusual way <strong>of</strong> moisture transfer <strong>in</strong> textiles. Experimental results will be compared with the theoreticalones.Thema: Air transmission <strong>in</strong> the plane <strong>of</strong> protective garmentsSupervisors: pr<strong>of</strong>. Ing.

That is why newstandards <strong>of</strong> test<strong>in</strong>g <strong>of</strong> cloth<strong>in</strong>g under conditions simulat<strong>in</strong>g the real radiation flux were developed <strong>in</strong> the lastdecade. However, heat flux <strong>in</strong> these test<strong>in</strong>g systems is measured by means <strong>of</strong> dynamic thermal calorimeters,which exhibit certa<strong>in</strong> disadvantages. In the <strong>study</strong>, a novel method <strong>of</strong> determ<strong>in</strong>ation <strong>of</strong> thermal resistance <strong>of</strong>firemen cloth<strong>in</strong>g will be used, which is based on the use <strong>of</strong> vertical hotplate which enable steady state heatflux measurements by means <strong>of</strong> special high temperature resistant sensors.Thema: Cool<strong>in</strong>g efficiency <strong>of</strong> fabrics made <strong>of</strong> micro and nan<strong>of</strong>ibresSupervisors: pr<strong>of</strong>.

In the <strong>study</strong>, the effect <strong>of</strong> the mentioned parameters <strong>of</strong>fabrics made <strong>of</strong> micro- and nan<strong>of</strong>ibres on their cool<strong>in</strong>g flow will be theoretically and experimentally analyzed.Thema: Air permeability <strong>of</strong> fabrics as the function <strong>of</strong> the air humidity and temperatureSupervisor: pr<strong>of</strong>. Ing. Luboš Hes, DrSc. Dr. h. c.Supervisor specialist: doc. Ing Vladimír Bajzik, <strong>Ph</strong>.D.Contact email <strong>for</strong> more <strong>in</strong><strong>for</strong>mation: lubos.hes@tul.cz, vladimir.bajzik@tul.czIn last decades, many studies were published, <strong>in</strong> which the effect <strong>of</strong> the air humidity and temperature on thefabrics air permeability was theoretically and experimentally analyzed. However, most <strong>of</strong> the studies refers tothe fabric permeability at the standard laboratory conditions, but <strong>in</strong> the real life, fabrics are also used atdiferent climatic conditions. The purpose <strong>of</strong> the <strong>study</strong> is to <strong>in</strong>vestigate theoretically and experimentally the airpermeability (air flow) <strong>of</strong> selected textile fabrics (differ<strong>in</strong>g <strong>in</strong> structure and composition) at large extension <strong>of</strong>the air humidity and temperature.

The drape pr<strong>of</strong>ile exhibits cyclic changes <strong>of</strong> the drape shape <strong>in</strong> the polardiagram when the same fabric is dynamically stressed. The experimental <strong>study</strong> will be based on thedevelopment <strong>of</strong> the <strong>in</strong>strument and s<strong>of</strong>tware <strong>for</strong> measurement <strong>of</strong> the dynamic drape coefficient. Thetheoretical part aims at the description <strong>of</strong> the mathematical model <strong>for</strong> the prediction <strong>of</strong> the drape pr<strong>of</strong>ile <strong>of</strong> thefabric.
