Sulfur dyes are insoluble in water but soluble in solution of alkaline reducing agents that convert them into their leuco form in which they have high affinity for fibre. Sulphur dyes liquid blacks are fully or partially reduced liquids. Since Sulphur black liquids have substantivity for cellulose, therefore they are ready for immediate use. Calculated amount of reducing agent may be required during application. Sulphur black liquid dyes are designed for use in continuous process using Rope and Slasher dyeing denim techniques as well as batchwise processing using Jig, Wench, and Jet dyeing techniques. All liquid products are available in redder as well as greener tones.
Sulphur Liquid Black Q:- Fully reduced Liquids requiring negligible addition of reducing agent at the time of application.
Sulphur Liquid Black B:- Environmentally friendly partially reduced liquid having low sulphide content. Calculated amount of reducing agent will be required during application.
Sulphur Liquid Black BLS:- Environmentally friendly partially reduced concentrated liquid having negligible free sulfides content. Calculated amount of reducing agent will be required during application.
Sulphur Liquid Black:- Sulphur liquid dyes are developed from the Sulphur Dyes by a solubilisation process and are characterized by their complete solubility in water, whilst maintaining the many advantages of the conventional Sulfur dye. It has negligible free sulfides content. In water solution they are virtually non-substantive, a property which makes them useful for many specialized dyeing techniques.
Sulfur Black Powder:- Conventional Sulfur black dyes in powder form available in various strengths. Widely used in traditional textile process houses that use batch operations using Jig, Wench, and Jet dyeing techniques.
Sulphur liquid black specially developed for the pulp & paper industry is a partially reduced liquid product with negligible free sulfides content ensuring no release of hydrogen sulphide gas during the acidification process.
Sulphur Liquid Black BLS-P:- Sulphur Liquid Black BLS-P is an environmentally friendly liquid product that has application in dyeing wide range of pulp & paper. It is used in laminate, decor, packaging and industrial papers.
Solubilized Sulfur Black is a highly water soluble dye that has application in dyeing leather to provide deep penetration.
Sulphur Liquid Black:- Sulphur liquid dye is Solubilized Sulfur Black and has negligible free sulphide content. It's high solubility in water provide the advantage of deep penetration in leather as compared to conventional direct dyes.
Sulphur Black Powder:- Conventional Solubilized Sulfur Black in powder form.
