Acid  dyes are water soluble dyes and generally applied on  wool with addition of acid  or acid salts. Acid dyes can also be applied on :

• Polyamide
• Silk
• Leather
• Paper.

 Acid dyes consists of dyes belonging to azo 1:1 Metal Complex, 1:2 Metal complex and acid milling dyes. These acid dyes  can be applied by different dyeing method depending on the class they belong.

We offer reactive dyes. Reactive dyes a chromophore contains a substituent taht is activated and allowed to directly react to the surface of the substrate. Reactive dyes are available in following range :


(a) Reactive cold brand :- dyes  also called M brand dyes are highly reactive requiring comparatively Milder condition  in dye fixation. Dyeing can be done at normal room temperature (about 25 to 30 degree C) by using soda ash. Reactive M Brand is applicable to cellulosie textile by batch wise and continues method in convenient textile machinery like open vat.

(b) Reactive HE Series :- (High Exhaust series dyes) He Dyes are reactive dyes for cellulosie material and are designed to give high fixation by exhaust dyeing method, when applied at temperature 75 to 90 Degree. HE Dyes are suitable for cotton and other cellulosie material. These Dyes process significantly higher exhaustion and fixation efficiency which result in appreciable cost reduction as compare to conventional reactive dyes.

( c) Reactive H Brand :- H Brand are monochlorotriazine  Reactive dyes having a low reactivity and low substantivity .Since these have low reactivity they required more severe condition for fixation with cellulosie material they are ready soluble  by pouring water of 80 to 85 Degree on powder and stirring well. They are applicable on cellulosie material by both dyeing and printing

(d) Reactive ME dyes :- (Bi – Functional ) ME Dyes are low temperature  high exhaust reactive dyes for dyeing padding  and printing of all dyes of  cellulosie material.these dyes offer high grade of all round fastness properties and excellent alkalis stability. Fixation temperature of these dyes  is 60 Degree

(e) Reactive VS Brand dyes :- are Reactive dyes possessing Vinyl sulphone as the reactive group in the process of alkalis, these  dyes chemically read which the hydroryl group of cellulosie  and form firm, convacend linkages.these dyes are versatile enough to suit different dyeing method. Results are excellent and shade come clean and brilliant no variation in dyeing and printing.

We manufacture a wide range of optical whitening agent that is used in a variety of papers, particularly in papers having high whiteness. Consequently, the papers have a bright fluorescent appearance under UV illumination.

• Optical whiteners
• Optical Whitening Agents (OBAs)
• Fluorescent Whitening Agents (FBAs)
• Fluorescent Whitening Agents (FWAs)

All optical whitening agents are dyes that absorb light in the ultraviolet and violet region (usually 340-370nm) of the electromagnetic spectrum and re-emit light in the blue region (typically 420-470nm). Our range of whiteners is fabricated using fluorescent activity which has a rapid emission reaction. Using these additives enhances the appearance of color of paper or fabric, resulting in a supposed whitening effect. This method increases the general quantity of blue light reflected, making the material appear less yellow. 
 
Fluorescent dyes such as umbelliferone and stilbenes are the most familiar chemicals having the whitening property. They attract energy in the UV fraction of the spectrum and re-emit it in the blue fraction of the visible spectrum. After being treated with an optical whitener, a white surface appears whiter as it discharges additional visible light than shines on it. The yellow and brown tones of the material are hided by the blue light released by the whitener, making the material appear whiter.

Solvent dyes are used to colour :

Organic solvents
Hydrocarbon Fuels
Waxes Lubricants
Plastics

These solvent dyes are completely soluble in water and oil. These solvent dyes are insoluable in water . They form a ollidal solution in solvents.  Solvent dyes are used for gold immitation of metalized polyester films. aLso used in making inks, inkjets inks and glass coloration.
