Abstract
Diplomové práce se zabývá studiem adheze nanovlákenných vrstev k nosným materiálům. Jako výchozí adhezní systémy byly použity disperze od firmy BASF a Collano. Teoretická část této práce je zaměřená na seznámení se základními pojmy souvisejícími s adhezi a její strukturou, adhezními systémy a způsoby jejich nanášení, kohezi, elektrostatickým zvlákňováním, výrobou nosné textilie spun-bond a způsobem testování zkoumaných materiálů. Experimentální část práce se zabývá nanášením adhezních systémů na nosnou textilii spun-bond a elektrostatickým zvlákňováním polyuretanu na adhezní vrstvy o různých plošných hmotnostech. U výsledných vzorků byla provedena mechanická zkouška oděru a zkouška prodyšnosti.
This graduation thesis dwell on studying of nanofibers' layers adhesion with support materials. As basic adhesion systems were used aqueous dispersions, made by BASF and Collano companies. Theoretical part of the graduation thesis is focused on basic concepts connected with adhesion and it's structure as well as adhesion systems and method of their spreading. In this part are also mentioned: cohesion, electrospinning, making support textile spun-bond and finally way of testing in connection with surveyed materials. Experiment part of the graduation thesis is focused on method of spreading adhesion systems on the support textile spun-bond and also on electrospinning of polyurethane on the adhesion layers - with different surface weights. With final samples were made testing of abrasion and permeability testing.
