Abstract
Tato diplomová práce je zaměřena na prozkoumání vlivu strukturních parametrů multifilové tkaniny na prodyšnost. V rámci jejího zpracování byla nejprve podrobně prostudována dosavadní teoretická základna zaměřená na téma struk-tury monofilu, multifilu a tkanin z něj vyrobených a také na zatím zjištěné po-znatky o prodyšnosti a pórovitosti tkanin. Dále pak byly proměřeny vzorky režných multifilových tkanin, především průměry a šířky nití v osnově a útku a velikosti pórů. Ty pak byly přepočteny na zakrytí a pórovitost a následně byly zjištěné hodnoty srovnány s naměřenou pro-dyšností a byly popsány zjištěné vztahy mezi zjištěnými veličinami.
This diploma thesis is focused on exploration of influence of the multifilament fab-ric structure parameters on the air permeability. At the first part there are the current theories of the structure of monofilament, multifilament and fabric and their influence on the air permeability and fabric po-rosity summed. At the next - experimental part, the samples of grey multifilament fabrics were measured. The multifilament diameter was calculated, width of the multi-filament in warp and weft and pores area were measured. The cover factor and porosity were calculated and these results were compared with measured values of the air permeability. The founded relations among values were described.
