Předložená disertační práce se zabývá přípravou liposomů (mikroenkapsulovaných forem) textilních barviv a pomocných barvířských prostředků a jejich převedením na suchou formu usušením na rozprašovací sušárně.
Byly připraveny suché formy liposomů přímých, reaktivních, disperzních a kyselých barviv. Dále byly připraveny liposomy NaCl, u kterých byla přídavkem kationických látek ovlivňována hodnota ZETA potenciálu. Dále byly připraveny liposomy dispergátorů (Spolostan 4P) a síranu amonného. Jejich účinek v procesu barvení byl srovnatelný s účinkem mikroenkapsulovaného barviva.
Pomocí vytahovacích křivek, stanovením sytostí vybarvení a celkové barevné diference vybarvovaných materiálů byl studován vliv mikroenkapsulovaných forem barviva na změny procesu barvení textilních substrátů za laboratorních podmínek. Byl potvrzen vliv mikroenkapsulace na koloristické chování barviv.
Prakticky použitelný je poznatek krytí pruhovitosti polyamidového hedvábí aplikací mikroenkapsulovaných forem kyselých barviv a/nebo síranu amonného. V tomto případě se jedná o nový a dosud nepublikovaný poznatek.
Významné je také zvýšení sytosti vybarvení použitím mikroenkapsulovaných forem ve srovnání s typovou formou barviva.
Annotation in English
The dissertation concerns preparation of liposomes (microencapsulated forms) of textile dyes and textile auxiliary agents and their conversion into the dry form employing spray dryer.
Liposomes of direct, reactive, disperse and acid dyes were prepared and converted into the dry form. Liposomes of NaCl were prepared and values of their ZETA potential were influenced by addition of cationic substances. Liposomes of dispersants (Splostan 4P) and ammonium sulphate were also prepared. Their effect in process of dyeing was comparable with effect of microencapsulated form of textile dye application.
Interference of dyeing processes (laboratory conditions) while applying of microencapsulated forms of textile dyes was studied. This was done by comparison of exhaust curves and by assesment of depth of shade of dyeing and total colour difference values.
Impression of microencapsulation technology colouristic bahaviour of textile dyes was confirmed.
Barriness affection (decrease) of polyamide silk dyeing by microencapsulated forms of acid dyes and/or ammonium sulphate represents practical usable finding (new finding, still no publish).
Increasing of depth of shade of dyeing by microencapsulated forms (in comparison with conventional dyeing) brings also practicall evidence.
