Colours

loggaUp until the mid-1980’s yarns here at Wålstedts were dyed by hand in open vats. Lasse Wålstedt developed a system which he named “The practical colour system”. This system served as a reference and key in order to help the manual dying process. He used the method of vat dyeing which with only a few dye baths gave all the colours of the colour circle. The dyes used were very hardy and colour variations were achieved when the yarn was dyed multiple times. With Indigo as a base, blue and green colours were dyed in a unique brilliance which today has never been replicated. Today modern dyes for wool and computer operated dyeing machines are used. In tune with today’s demanding environmental requirements, colours have been developed to be adsorbed by the yarn by almost 100 percent. With such dyeing methods, heat is saved as the dye bath can be recycled up to ten times by simply adding more pigment and chemicals. Fifteen different pigments are used that can be combined to dye thousands of different shades. The dyeing then takes place in a closed dyeing machine. These colors can be re-dyed to achieve light refraction effects.
