Abstract
Diplomová práce se zabývá nešpinivou úpravou textilií. Práce popisuje špínu a její složení, hlavní faktory ovlivňující špinivost textilií, druhy nešpinivých úprav a prostředky pro získání nešpinivé úpravy. V rámci vypracování diplomové práce bylo osloveno několik českých a zahraničních společností, které nešpinivé textilie vyrábějí. Laboratorně byl vyroben materiál s obsahem TiO2 částic. U textilií byly zjišťovány základní parametry, jako je tloušťka, jemnost přízí a plošná hmotnost. Pomocí elektronové mikroskopie byl zkoumán povrch textilie a přítomnost nešpinivé úpravy. Ke zjišťování špinivosti textilií byly navrženy speciální metody a následně byly textilie experimentálně otestovány. Byl měřen kontaktní úhel mezi textilií a kapkou destilované vody, červeného vína a oleje. Dále byla sledována špinivost pomocí nové metody založené na sbírání modelové nečistoty valící se kapkou vody. Cílem práce je zhodnotit kvalitu textilií s nešpinivými úpravami, které trh nabízí. V ekonomické části se práce věnuje cenám těchto materiálů a pomocí dotazníků byl realizován průzkum trhu a řešen potenciál zákazníka.
This thesis deals with the anti - soiling finish of fabrics. The work describes the soil and its composition, the main factors influencing the staining rate of textiles, the types of anti - soiling finish and the agents to get anti - soiling finish. Several Czech and foreign companies which produce self - cleaning fabric were approached in developing of this thesis. The materials containing TiO2 particles were made in laboratory. The basic parameters of fabric such as thickness, yarn fineness and areal mass fabrics were evaluated. Using electron microscopy has been studied surface fabric and the presence of anti - soiling finish. The staining rate was surveyed by designed methods and the textiles were tested experimentally later. The contact angle was measured between the fabric and a drop of distilled water, red wine and oil. Furthermore, the staining rate was observed by new method. The method is based on collecting of model soil by rolling drop of water. The aim of this thesis is assess the quality of self - cleaning textiles, which market offers. The economic part deals with the prices of these materials and the research of market was carried out by using of questionnaires and the potential of customer was dealt with.
