RAJAFIX REACTIVE ME BRAND DYES are mixed Bifunctional reactive dyes where Vinyl Sulfone group is linked to chromophore through a mono chloro triazine group as a bridge link. They are applicable on cellulosic material at lower dyeing temperature 60^oC. The main features of these 'Bifunctional' dyes are as under :

• The dye-fibre bond between Vinylsulphone group and cellulose is stable to acid hydrolysis, so that stability of dyed goods in industrial acidic atmosphere is very good with the time lapse.       
• The dyes which are not fixed during the dyeing process can be washed off easily because the hydrolyzed dye has low substantivity and thus there is a little risk of staining of adjacent whites.       
• Excellent leveling properties.           
• Better reproducibility in dyeing.       
• High exhaustion and high fixation efficiency.       
• Good all round fastness properties.    

Bi-functional dyes are applicable on cellulosic materials by dyeing as well as printing methods.

Remazol 'VS' Brand Dyes are Reactive Dyes possessing Vinyl sulphone as the reactive group. In presence of alkali, these dyes chemically react with the hydroxyl group of cellulose and form firm, convalent linkages. These dyes are versatile enough to suit different dyeing methods. Results are excellent and shades come clean and brilliant with no variation in dyeing as well as in printing.
'VS' dyestuffs posses poor affinity for cellulosic fibers in absence of salt and alkalis. For this reasons, they are suitable for use on pad. Their substantivity can be increased by addition of giauber's salt or common salt and alkali, making the dyestuff suitable on all conventional dyeing machine for loose material, yarn in hanks and packages and piece goods. The dyeing methods may therefore, be classified under the padding and exhaust processes, standing baths are not recommended, as in alkaline medium inactivation of the dyestuffs by reaction with water takes place as a side reaction.

VS dyestuff posses poor affinity for cellulosic fibres in absence of salt and alkalis. For this reasons, they are suitable for use on pad. Their substantivity can be increased by addition of glauber's salt or common salt and alkali, making the dyestuff suitable on all conventional dyeing machines for loose material, yarn in hanks and packages and piece goods. The dyeing methods may therefore, be classified under the padding and exhaust processes, standing baths are not recommended, as in alkaline medium inactivation of the dyestuffs by reaction with water takes place as a side reaction.

The main features of VS dyes are :

• Process excellent brightness and good wet fastness.       
• They are dischargeable.       
• They are suitable for exhaust & different pad dyeing methods and discharge printing.       
• Ease of washing off unfixed dyestuffs i.e. minimum staining of the white grounds in printing.       
• They are applicable at 40^oC and 60^oC.   

We manufacture of reactive high exhaust dyes, optimum quality reactive high exhaust dyes which are highly apt for the dyeing purpose of cellulosic and other cotton materials. We stand a bit above the traditional dyes because of the higher fixation and exhaustion efficiency of the dyes which reduces the cost involved appreciably. Good build up are of particular importance for dyeing polyester and cellulic blends of garments which holds the dye for longer period. As compared to the conventional dyes the wastage too is less which makes us the one among the best he cotton dye manufacturers. We stand supreme among the prime reactive dyes exporters from india.

We are offering reactive m dyes, reactive m brand dyes are highly reactive requiring comparatively milder conditions in dye fixation. They are primarily meant for dyeing at normal room temperature (about 25 - 30 deg. C) using soda ash or sodium bicarbonate. Parshwactive m brand dyes are applicable to cellulosic textiles by batch-wise, semi-continuous and continuous methods in conventional textile machinery like open-vat, package, jet, jig, winch and padding mangle. The versatility in various application procedures and the availability of wide range of bright and fast shades are the outstanding features of this class of dyestuffs. We offer one of the best quality reactive cold brand dyes which are highly demanded by all. We are also one of the well known reactive cold brand dye manufacturers and exporters from india. general characteristics of 'm' brand dyes stabilitythe dyestuff should be stored in cool and dry conditions. The containers should be tightly closed when not in use. High temperature, humidity and alkaline ph conditions reduce the stability of the dyes in solution. water supplysoft of the softened water should be employed, avoiding alkalinity especially while dissolving the dyes. When hard water is available, it should be softened with sequestering agents. In dyeing, the ph of the water supply should be within the limits ph -7-8. method dyeingreceive cold water in the dye bath (recommended ml ratio 1 to 15), add required quantity of common salt or gluber salt. Paste required dyes with the water and dissolve by adding water 30 c to same. Add dissolved dye to the dye bath. Enter material and run till 15 to 20 minutes. Add required amount of soda ash (as solution) and again run the material for 45 to 60 minutes, squeeze, wash with water and soap at boil with 2gl soap, wash with water and dry. Soaping treatment is highly essential to remove unfixed dye to produce dyeings of high washing fastness.
