Abstract
The modern textile finishing industry faces the challenge of breaking new ground and making radical changes. Since the textile industry is one of the biggest polluters, it is necessary to develop new ecologically and economically sensible methods of finishing, dyeing, textile care, etc. The studies presented here were carried out to achieve colour effects on textiles by using natural dyes of plant origin extracted from onion skins in the screen-printing process. Flavonoid dyes extracted from onion skins were used, which belong to the group of mordant dyes due to their dyeing properties and require the addition of metal salts. For this reason, the possibility of pre-treating cotton material by cationisation and argon plasma as well as a combination of these methods was investigated. It has been shown that these methods of cotton treatment prior to screen printing can replace the use of aluminum salts in the printing paste when it comes to achieving colour parameters and satisfactory fastness properties.
