Product Range

Textile

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. Bhanu's Sulphol liquid blacks are fully or partially reduced liquids. Since Sulphol liquids have substantivity for cellulose, therefore they are ready for immediate use. Calculated amount of reducing agent may be required during application. Sulphol 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.

Sulphol Liquid Black Q	Fully reduced Liquids requiring negligible addition of reducing agent at the time of application.
Sulphol Liquid Black B	Environmentally friendly partially reduced liquid having low sulphide content. Calculated amount of reducing agent will be required during application.
Sulphol Liquid Black BLS	Environmentally friendly partially reduced concentrated liquid having negligible free sulfides content. Calculated amount of reducing agent will be required during application.
Sulphosol Liquid Black	Sulphosol liquid dyes are developed from the Sulphol 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.
