Disperse dyes are synthetic dyes. Additionally, it is one kind of organic substance that is free of ionizing groups. In fact, disperse dyes are less soluble in water and used for dyeing synthetic textile materials. Basically, disperse dyes uses for dyeing polyester yarn or fabric. On the other hand, Reactive dyes are used for coloring cotton or cellulosic fiber.
A question could appear in your mind why this dye is called disperse dyes? It has a simple answer. Disperse dye is so-called because it is nonsoluble and molecularly dispersed therefore dispersing agent is necessary for coloration with dispersed dyes.
Properties of Disperse Dyes:
The following are the properties of dispersed dyes. they are-
- Firstly, disperse dye is one kind of organic substances which is free of ionizing group.
- Secondly, this dye is non-soluble in nature.
- Thirdly, disperse dye is insoluble in water.
- Therefore, dispersing agent is essential for dyeing with disperse dyes.
- Fastness properties such as wet and light fastness is good to excellent.
- After that, disperse dyes apply in acidic condition.
- Moreover, disperse dyes widely use for dyeing synthetic fibers. Polyester fiber is dyed by disperse dyes but nylon, acrylic also can be dyed with this.
- Disperse dyes dyeing significantly carry out in high temperature.
- In some case carrier method is applied for dyeing of polyester with disperse dyes
- Besides this, disperse dyes are economical.
- Molecular size of disperse dyes are smaller than other dyes.
- Lastly, disperse dyes are derivatives of azo, anthroquinone, nitro and quinine groups.
In sum, different dyes manufacturing companies manufacture disperse dyes. So, choose your color brand which you can trust for better dyeing.
