    • The Series that we offer is shown below:

      Hot Dyes

      These are named as 'HOT NAMED DYES'. These dyes are applied under strong alkaline conditions at high temperature of application compared to 'M' Dyes. These Dyes contains very good fastness properties to wash, perspiration, light etc. These dyes are suitable particularly for printing cotton, viscose.

    • 'M' SERIES DYES

      These are called 'COLD BRAND DYES'. These dyes are having very good reactivity fastness properties. These dyes require milder alkaline conditions for applications & fixation at the optimum temperature of 25-35 deg c.

    • 'HE' SERIES DYES

      These dyes belong to the new class of SunActive® Dyes, having high substantivity and superior exhaustion. HE dyes are recommended for dyeing of cellulosic material by batchwise method on jigger, winch or open vat etc, for obtaining brighter shades.

    • 'ME' SERIES DYES

      We introduced a new range of bifunctional reactive 'ME' Dyes for our customers who are too conscious of energy consumption. In 'ME' Dyes one molecule is fused with two reactive group vinyl sulphone as well as monochlorotriazine.

FREQUENTLY ASKED QUESTIONS

Reactive dyes are a class of highly coloured organic compounds that form a covalent chemical bond with the fibre molecules during dyeing — typically with hydroxyl groups in cellulosic fibres like cotton. This chemical bond makes reactive dyes extremely wash-fast and durable compared to other dye classes. They require alkaline conditions (usually with soda ash or sodium hydroxide) and heat for fixation.
M Series (Cold Brand) reactive dyes have high reactivity and fix at low temperatures of 25–35°C under mild alkaline conditions, ideal for sensitive fabrics. HE Series (High Exhaustion) dyes have high substantivity and are used in batchwise dyeing (jigger, winch) for brighter shades with better exhaustion. ME Series (Bifunctional) dyes contain two reactive groups (vinyl sulphone + monochlorotriazine) in one molecule, offering better fixation efficiency and making them suitable for energy-saving dyeing processes.
Reactive dyes are primarily used on cellulosic fibres including cotton, viscose/rayon, linen, jute, and hemp. They can also be applied to silk and wool, though different reactive chemistry and process conditions may be required. They are not suitable for polyester or nylon, for which disperse dyes and acid dyes respectively are used.
Reactive dyes offer excellent wash fastness (4–5 rating), good light fastness, perspiration fastness, and rubbing fastness. Their covalent bond with the fibre gives them superior durability compared to direct or vat dyes. High exhaustion (HE) series dyes specifically offer superior exhaustion and fixation rates, minimising dye waste in the effluent.
India is a significant global producer of reactive dyes, with manufacturers supplying to textile mills in Asia, Africa, and Europe. Vipul Organics Ltd. is a leading reactive dyes manufacturer and exporter in India, offering a comprehensive SunActive® range across Hot Brand, M Series, HE Series, ME Series, and Vinyl Sulphone categories — including Reactive Black, Reactive Red 195, Reactive Yellow 145, Reactive Blue 21 & 222, Reactive Orange 35, and specialty grades like Reactive Super Black R/G and Reactive Black WNN.
