Reactive Dyes
Reactive dyes are the dominant dye class for cotton and cellulosic fibers, forming covalent bonds with cellulose hydroxyl groups under alkaline conditions to produce wash-fast, bright shades with excellent rubbing and perspiration fastness that meet the demands of modern retail washing programs and global export compliance requirements. Available in mono-, bi-, and multi-functional reactive chemistries (vinyl sulfone, monochlorotriazine, bifunctional), reactive dyes offer an unmatched combination of brilliant color strength across the complete spectrum, reproducible shade matching, and the durability required for quality garment and fabric programs. Cold pad-batch, exhaust, and continuous pad-steam processes all accommodate reactive dyes, making them the standard choice for high-quality cotton fabric and garment dyeing.
Key Applications
- High-quality exhaust dyeing of cotton fabric and yarn for fashion and export
- Cold pad-batch reactive dyeing of cotton woven fabric at ambient temperature
- Continuous pad-steam dyeing of cotton fabric in solid and multicolor designs
- Reactive dyeing of viscose, modal, and lyocell fibers
Frequently Bought Together
Direct Dyes
Direct dyes are anionic water-soluble azo and stilbene colorants that exhaust directly onto cellulosic fibers from a neutral or weakly alkaline electrolyte bath without the need for chemical fixation auxiliaries, making them among the simplest and most cost-effective dye classes for cotton, viscose, and linen in commodity shades across a full color range.
Textile Dyes & AuxiliariesIndigo Blue
Indigo Blue is the iconic vat dye responsible for the distinctive blue color of denim fabric, applied to cotton warp yarns by continuous rope or slasher dyeing using a sodium hydrosulfite reducing bath followed by air oxidation in multiple dip-nip cycles to build up the characteristic surface-dyeing that produces the ring-dyeing effect essential to authentic denim fading behavior.
Textile Dyes & AuxiliariesSulphur Dyes
Sulphur dyes are a broad class of inexpensive, water-insoluble colorants for cellulosic fibers that are applied in solubilized leuco form from an alkaline sodium sulfide reducing bath, exhaust onto cotton at moderate temperatures, and are then re-oxidized within the fiber to form their insoluble colored structure.
