Abstract
Tato práce je zaměřená na zkoumání vlivu vlhkosti na ohybovou tuhost. V teoretické části jsou představeny pojmy ohybová tuhost, přistroj, na kterém se ohybová tuhost měří, klimatické podmínky za jakých se měří a dosavadní výzkum.V praktické části byla zkoumána ohybová tuhost na tkaninách, které poskytla společnost SYNTEX s.r.o. Měření čtvercových vzorků bylo provedeno na přístroji TH-7 a pomocí klimatické komory byly vzorky klimatizovány na předem určenou vlhkost a teplotu. Data z TH-7 byly exportovány do programu EXCEL a z něho vyhodnocovány pomocí grafů a jednofaktorové analýzy ANOVA, která byla ověřena Tuskeyho testem. Dále bylo zkoumáno zakrytí textilií pomocí obrazové analýzy. Na základě výsledků měření ohybové síly při různé vlhkosti byla nalezena funkční závislost pro vliv vlhkosti na ohybovou tuhost.
This thesis is focused on analyzing the effect of humidity on bending stiffness. The theoretical part introduces the concepts of bending rigidity device to which the bending stiffness measures, the climatic conditions under which it was measured and current research. In the practical part was investigated bending rigidity on fabrics provided by the company Syntex Ltd. Square measurement of samples was performed on a TH-7, and use the climatic chamber, the samples were conditioned at a predetermined humidity and temperature. Data from the TH-7 were exported to Excel and from him evaluated using graphs and a one-way ANOVA was validated Tuscey test. Furthermore, it was examined covering fabrics using image analysis. Based on the measurement results of bending forces at different humidity was found functional dependence for the effect of humidity on the bending stiffness.
