Dyeing of Wool




Wool in its natural form features a neutral shade and has got to be dye to get varied hues. In most cases, wool are often bleached or dye at any of the processing stages though it's commonly done after washing or when it's spun into yarn. Wool which is dyed at the yarn stage is mentioned as yarn dye while stock dye wool is that the name given to wool which is dye right after washing. Plant colours are often used for a natural dyeing process though chemical are those preferred for commercial applications. The dyes used for wool are chemically anionic in nature. Two factors that determine the speed of dyeing are the pH and therefore the rate of increase in temperature of the dye bath liquor. Wool is claimed to be dye or bleached successfully if one achieves the uniformity, correct shade, requirements of colour fastness at minimum cost and least environmental damage on a uniform basis.

There are several which go down well with wool fabric to develop colourfast finish in varied hues starting from soft pastels to intense brights. Wool is generally dye using dye . These require extremely hot waters for consistent results. Acid are cheaper and wash fast and provides best results as far as wool cares . The resulting colour depends on the number of dye used, temperature, time that the material is immersed within the dye and therefore the length of the material . Wool are often dyed using direct too. However, these don't have the vivid brightness and aren't so wash fast. Cellulose fibres are dyed with these directly without using mordants. Reactive on the opposite hand were initially used for cellulose fibres alone. However, today, varied sorts of this dye are wont to dye wool, nylon, silk, acrylics along side their blends.

Yarn of wool is completed either at hank form or at-package form; however, the hank form is more popular. Yarns of wool are immersed during a large container containing the dye bath from a rung over which they're hung. Wool yarns are dye in bulk by this method as this helps to realize maximum colour penetration.

Wool are often dye within the loose-fibre stage too. Bales of scoured wool are first weighed before being delivered to the house. they're then opened near the machine after which they're manually immersed into the vessel. For achieving even loading into the machine the fibre could also be made wet before being packed.

Woolen garments in beautiful patterns are flaunted on fashion ramps with leather boots in various shades to match. All because of the acid direct dyes and leather dyes!

The continued growth and expansion led to formation of several subsidiary plants. However, one thing remains common across the plants is strict adherence to quality norms, compliance of statutory formalities and industry best practices.
