New Dyes and Application Technologies Developed at University of Pardubice

Popis výsledku v původním jazyce

The paper concerns following subjects. A/ New reactive dyes for dyeing wool based on N-methyl-N-carboxymethyl-2-aminoethyl-sulfonyl reactive group (-SO2CH2CH2N(CH3)CH2COOH), where covalent bond between dye and fibre is formed in an acid bath. The dyed wool exhibits very high wet fastness. B/ Black mordant dyeing of wool, where oxidative bichromates (or chromates) are substituted by hydrogen peroxide. C/ Preparation and formulation of liposomes of textile auxiliaries suitable as an additive to the dye-baths. The encapsulated textile auxiliary agent is used for the encapsulation of water-soluble or water-insoluble dye, in such a way that first the dye is dissolved or dispersed in water, whereupon the liposome of textile auxiliary agent (e.g., salt or dispersant) is added. Since the textile auxiliary agent rapidly diffuses through the membrane, it is gradually dissolved in water. On the other hand, the dyestuff or pigment, having a large molecule and much lower solubility in water, is exp
