    In this baccalaureate work are measured mechanical properties of 10 samples of semi-permeable fabrics. The theoretic part deals with the wear comfort of semi-permeable fabrics and offers their common classification. In addition there are described also investigated mechanical properties and methods of their measurement. The experimental part contains information about the measurement itself. There were investigated shearing and bending rigidity, extensibility, drapeability and abrasive resistance. In addition was measured surface mass. The interpretation contains both results of measurement and individual characteristics comparison. The conclusion is devoted to the marketing research which was performed by questioning. Its purpose was to find out the interest of users in the surveyed materials and also their disparity perception between wearing rigid and elastic semi-permeable fabrics.

    Vliv neplstivých úprav na tepelný komfort vlněných tkanin

    This thesis observes the influence of anti-felt finishing on thermal comfort of woollen fabrics on wet state. The theoretical part contains a description of the sheep wool as well as information about anti-felting treatments. It also deals with thermophysiological comfort. In the practical part is described performing of anti-felting treatments - acid wet chlorination, enzymatic hydrolysis, laser treatment. Thermal resistance, thermal conductivity and thermal absorptivity were measured for both, treated and untreated fabrics, in different wet states. The measurement was carried out with measuring advice called Alambeta. The evaluation was performed using the regression graphs and cluster analysis. It was found that the treatments based on the partial destruction of the fibre surface lead to the deterioration of thermal comfort of woollen fabrics on wet state. The final part explains the causes of these changes.
