Basic Dyes are cationic soluble salts of coloured bases. Basic dyes are applied to substrate with anionic character where electrostatic attractions are formed. Basic dyes are not used on cotton as the structures are neither planar nor large enough for sufficient substantivity or affinity. Basic dyes are called cationic dyes because the chromophore in basic dye molecules contains a positive charge. The basic dyes react on the basic side of the isoelectric points. Basic dyes are salts, usually chlorides, in which the dyestuff is the basic or positive radical. Basic dyes are powerful colouring agents.Its applied to wool, silk, cotton and modified acrylic fibres. Usually acetic acid is added to the dyebath to help the take up of the dye onto the fibre. Basic dyes are also used in the coloration of paper. ADVANTAGES:- High Tinctorial strength Moderate substantively Relatively economical Wide shade range Includes some of the most brilliant synthetic dyes Shows good brightness

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.
1.Reactive dyes are anionic dyes, which are used for dyeing cellulose, protein and polyamide fibres. 2.Reactive dyes are found in power, liquid and print paste form. 3.During dyeing the reactive group of this dye forms covalent bond with fibre polymer and becomes an integral parts of the fibre. 4.Reactive dyes are soluble in water. 5.They have very good light fastness with rating about 6. The dyes have very stable electron arrangement and can protect the degrading effect of ultra-violet ray. 6.Textile materials dyed with reactive dyes have very good wash fastness with rating Reactive dye gives brighter shades and has moderate rubbing fastness. 7.Dyeing method of reactive dyes is easy. It requires less time and low temperature for dyeing. 8.Reactive dyes are comparatively cheap 9.Reactive dyes have good perspiration fastness with rating 4-5. 10.Reactive dyes have good perspiration fastness.
Acrylic (Cationic) Dyes are specially developed for dyeing Acrylic Fibre which is widely used in the manufacturing of Blankets, Carpets, Knitting Goods, Decorative Fabrics, Fur Toys, Dress Materials, Sarees, etc. These dyes are characterized by their strong tinctorial power, outstanding brightness and excellent fastness properties. They are also suitable for Dyeing and Printing which are free from German Banned Amines. They are water soluble mainly applied to acrylic fibres, but some use for wool and silk. Usually acetic acid is added to the dyebath to help the uptake of the dye onto the fibre. APPLICATION: Please refer to our technical for further information. Sr. No.Product NameC.I. NameC.I.
