Electrokinetic properties of wool and cotton fabrics dyed with the flower extract of spanish broom plant

The use of natural dyes derived from natural plant sources for textiles dyeing has increased in recent years as consumers increasingly desire to replace synthetic chemicals with natural compounds. A natural dye from Spanish broom was produced by aqueous extraction. Wool and cotton fabrics were dyed in acidic medium. The electrokinetic properties of the dyed textiles were analysed as well as laundering durability and the colour fastness. The results showed that 5 washing cycles had no effect on the colour intensity of the dyed wool fabrics, suggesting that the pigments extracted from the flowers of Spanish broom have a high potential as a source of natural dyes, for protein rather than cellulosic fibres.
