Influence of Flavonoid Dyes on the Color and Pro - Health Benefits of Linen Fabrics

Abstract

ABSTRACT The paper presents analyses of flavonoid dyestuffs i.e., marigold (Tagetes patula L.), dyer’s broom (Genista tinctoria) and weld (Reseda luteola L.) Color analysis and potential health-promoting properties of linen fabrics dyed with extracts from the above-mentioned plants were also carried out. The study, based on many years of experience, led to carrying out dyeing with extracts of selected plants on an industrial scale and to creating a collection of naturally dyed linen apparels for adults and children. Dyeing was performed only with plant extracts. The experiments included fabric pre-treatment processes with the use of 5 mordants: alum, soda, citric acid, copper sulfate and iron sulfate. The paper discusses optimization of the dyeing process by testing the dyed fabrics spectrophotometrically and determining the colorimetric properties (L *, a *, b *) and the colors according to the Pantone (Color) Matching System (PMS). Laboratory research was implemented into industrial production line and a pilot collection of fabrics was made. These fabrics were used to make 2 collections of clothing with health-promoting properties for children and adults. Linen fabrics, with interesting, subtle colors, with antimicrobial activity showed positive effects on the skin, which was more moisturized and very well protected against UV radiation.,,
