1.Disperse dyes are nonionic dyes. So they are free from ionizing group.
2.They are ready made dyes and are insoluble in water or have very low water solubility.
3.They are organic coloring substances which are suitable for dyeing hydrophobic fibers.
4.Disperse dyes are used for dyeing man made cellulose ester and synthetic fibers specially acetate and polyester fibers and sometimes nylon and acrylic fibers.
5.Carrier or dispersing agents are required for dyeing with disperse dyes.
6.Disperse dyes have fair to good light fastness with rating about 4-5.
7.The wash fastness of these dyes is moderate to good with rating about 3-4.
8.Of all dyestuffs disperse dyes are of smallest molecular size.
9.Generally disperse dyes are derivatives of azo, anthroquinone, nitro and quinine groups.
10.They do not undergo any chemical change during dyeing.
11.In presence of nitrous oxide, textile materials dyed with certain blue and violet disperse dyes with an anthraquinone structure will fade. This is called gas fading of disperse dyes which is a defect of this dye.
Acid dyes are highly water soluble, and have better light fastness than basic dyes. The textile acid dyes are effective for protein fibers such as silk, wool, nylon and modified acrylics. They contain sulphonic acid groups, which are usually present as sodium sulphonate salts. These increase solubility in water, and give the dye molecules a negative charge. In an acidic solution, the -NH2 functionalities of the fibres are protonated to give a positive charge: -NH3+. This charge interacts with the negative dye charge, allowing the formation of ionic interactions. As well as this, Van-der-Waals bonds, dipolar bonds and hydrogen bonds are formed between dye and fibre. As a group, acid dyes can be divided into two sub-groups: acid-leveling or acid-milling.
