Abstract
Tématem bakalářské práce bylo provést povrchovou degradaci polyesterových vláken a folií působením alkálie, kyseliny a plazmy. Změny degradovaného povrchu polyesterových vláken byly sledovány pomocí barvících testů kationtovými a reaktivními barvivy. Polyesterová tkanina byla modifikována alkálií, kyselinou a plazmou v určitých časových intervalech. Jednotlivé časové modifikace byly obarveny a proměřeny na remisním spektrofotometru. Změna barevnosti byla sledována jako závislost K/S hodnoty na čase úpravy. Změny povrchu materiálu po alkalické a kyselé hydrolýze byly porovnávány pomocí rastrovací elektronové mikroskopie.
The topic of my bachelor work was to perform surface degradation of polyester threads and foils by the instrumentality of alkali, acid and plasma. Changes of degradated surface of polyester threads were monitored by colouring tests with basic and reactive dyes. Polyester fabric was modified by alkali, acid and plasma in specific time intervals. Particular time modifications were couloured and scaled by remising spectrophotometer. The change of colour scheme was monitored as dependence of K/S value on time of pretreatment. Changes of surface of material after an alkaline hydrolysis and acidolysis were compared by scanning electron microscope .
