Disperse dyes are less soluble in water and used for dyeing synthetic textile materials. Disperse dyes is mainly used for dyeing polyester yarn of fabric. in the other hand, Reactive dyes are used for coloring cotton or cellulosic fiber.
A question could be appear in your mind that why this dye is called disperse dyes? It has a simple answer. Disperse dye is so called because it is non soluble and molecularly dispersed therefore dispersing agent is necessary for cooperation with disperse dyes.

Properties of Disperse Dyes:

• Disperse dye is one kind of organic substances which is free of ionizing group.
• Disperse dye is non-soluble in nature.
• Disperse dye is insoluble in water.
• Dispersing agent is needed for dyeing with disperse dyes.
  Fastness properties specially wet and light fastness is good to excellent.
• Disperse dyes are applied in acidic condition.
• Disperse dyes are widely used for dyeing synthetic fibers. Polyester fiber is dyed by disperse dyes but nylon, acrylic also can be dyed with this.
• Disperse dyes dyeing is carried out in high temperature.
• In some case carrier method is applied for dyeing of polyester with disperse dyes
• Disperse dyes are economical.
• Molecular size of disperse dyes are smaller than other dyes.
• Disperse dyes are derivatives of azo, anthraquinone, nitro and quinine groups.

Disperse dyes dyeing is carried out in high temperature for this reason dyeing machine should have the capability of serving this process.

Different dyes manufacturing companies manufacture disperse dyes. Choose your color brand on which you can trust for better dyeing.
