Basic Dyes
Basic dyes (cationic dyes) are highly brilliant, intensely colored ionic colorants with strong affinity for acrylic, modacrylic, and paper fibers, and secondary affinity for mordanted wool and silk, providing saturated fluorescent-level hues in red, blue, yellow, green, and violet that cannot be achieved with any other dye class. On acrylic fiber, basic dyes exhaust from an acetic acid bath and form strong ionic bonds with the anionic sulfonate groups in the acrylic polymer chain, producing deep, level dyeings with good light fastness on properly dye-receptive fiber. The brilliant color strength and low cost of basic dyes make them the exclusive dyestuff class for acrylic fiber dyeing in both yarn and fabric form.
Key Applications
- Exhaust dyeing of acrylic yarn and fabric in vibrant shades
- Dyeing of acrylic-wool and acrylic-nylon blend fabrics
- Paper and leather coloring in specialty applications
- Mordant dyeing of wool and silk for craft and specialty use
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.
