The Washing Off Agent is suitably used in textile industries for removing hydrolyzed dye before coloring applications on fabrics designed from cotton. These compounds are formulated by making use of optimum grade constituents to make sure that these are blended with chelating properties. These chemical formulations are also superior for improvising the crocking and washing fastness.
Available Brand: Sequel-40
Sequel - 40 is efficient dispersing ( protective colloid) and chelating agent for all stages in the dyeing of textile made from cellulose and blends.
Chemical Composition: Acrylic copolymer
Solubility: Easily dilutable in cold water
Compatibility: Good resistance of acids, alkalies, & electrolytes, commonly used in dyeing liquors. Compatible with cationic mild alkaline conditions.
Sequel - 40 exhibits an excellent dispersing effect on Raw Cotton impurities (Waxes & Pentinates) and on the precipitates caused due to hard water.
Sequel - 40 also has a moderate chelating effect on metal ions. Consequently Sequel - 40 eliminates the adverse effect of Calcium and Mg ions on the solubility of anionic dyes & their affinity to cellulosics.
Sequel - 40 has limited chalating potential, insufficient to remove metal ions from metal complex dyes hence it does not impair the shade & fastness properties of dyeing obtained with reactive and direct, metal complex dyes.
Sequel - 40 is non-foaming with no affinity for anionic dyes.
Sequel - 40 is multifunctional auxiliary used for all stages in dyeing cellulosic and its blends. For continuous processes, 1-2/g/I of Sequel - 40 is recommended in padding bath.
In batch dyeing process following example are offered:
Dyeing Polyester / Cotton: 1-2 g/I Sequel - 40 at beginning of dyeing cycle,
Dyeing Cotton with Vat Dyes: High concentrations of Ca and Mg ions in grey cotton are responsible for substantial losses in color yield losses in liquorsof low to moderate hardness (150 mg Ca / Litr).(If water is of greater hardness then a stronger chelating agent will be necessary)
Dyeing Cotton with Reactive & Direct Dyes: if the water is hard, calcium carbonate may be precipitated during the dyeing of raw cotton with reactive and direct dyes. Sequel - 40 is very effective dispersant for the calcium carbonate thus formed and maintains it in a finely dispersed state. As a result, opalescence of the dyeingliquor is avoided.
All reactive Dye System needs Sequel -40 in the dyeing cycle to prevent following problems.
Dye Re-deposition during washing
Dulling of shades
