Description
The chemical essence and structure of Reactive Black 5. Reactive Black 5 is a diazo type dual-reactive dye that has set a new standard in the reactive dyes field. Its unique chemical structure is complex: two H acid residues act as coupling components, connecting azo groups to form the main conjugated chromogenic system. Reactive Black 5 has two reactive groups on the molecular side: usually a monochlorotriazine and a b-sulfate, ethylsulfone. It is a M-type dye. Reactive Black 5: Physical and chemical properties Reactive Black 5 powder is typically a uniform, grayish-black or black. The aqueous solution of Reactive Black 5 is black. It is readily soluble in water. Its dyeing mechanism, as a dual-reactive dye, is critical: its monochlorotriazine can undergo nucleophilic subtraction reaction with cellulose fibres at lower temperature, while its vinyl sulfone can undergo nucleophilic additive reaction under alkaline conditions. This dual reactive dye can bind fibers with two different covalent bonds, creating a “bridging effect”. Reactive Black 5 has a number of performance characteristics. Reactive Black 5 is designed to overcome the disadvantages of single reactive dyes, such as their low fixation rates and insufficient colorfastness. Its dual active group synergistic effect brings significant advantages: High fixation rate. Two active groups improve the rate of dye utilization, reduce the chromaticity in wastewater, and increase the reaction rate with fibers. The dyes are superior in many ways, including washfastness, chlorine water fastness and rub fastness.

The application of Reactive Black 5
1.High-end textile dyeing
Reactive Black 5 is primarily used to achieve the best black dyeing results.
Reactive Black 5 can be used to dye pure cotton fabrics, including woven and knitted fabrics. Reactive Black 5 is the dye of choice for black cotton products due to its deep black color, excellent washing and rubbing resistance and high quality.
Reactive Black 5 can also be used to dye fibers like viscose and modal. This will help overcome the low colorfastness of these fibres when dyed directly. It produces high-quality fabrics for underwear, homewear and fashion.
Reactive Black 5 is also suitable for dyeing cotton in interwoven or blended fabrics, such as cotton/polyester or cotton/spandex. To obtain a fabric that is uniformly black and has a high level of fastness, it is usually dyed with polyester first, and then with cotton using Reactive Black 5.
Reactive Black 5, a dye for hemp fabrics, such as ramie or linen, is used to meet the demand of the market for black natural hemp clothing and textiles.
2.Fields that require special colorfastness requirements
Reactive Black 5 Dual Active Baseband is indispensable for textiles that need rigorous processing due to its high fixation rate, strong bonding abilities and high bonding rates.
Reactive Black 5 is suitable for textiles used in hotels, such as bedsheets, duvets, pillowcases and towels. Reactive Black 5 has a high washfastness, which ensures that the color will remain deep even after high-frequency industrial washing.
Medical apparel and public textiles – meet their strict washing and disinfection requirements.
Reactive Black 5 can be used for black sportswear, outdoor clothing and other products. Its excellent sun and moisture resistance guarantees color stability even after prolonged sun exposure or sweat immersion.
Reactive Black 5 is a dye that has a better resistance to chlorine than many other reactive dyes.
3. Printing and Special Craftsmanship
Reactive Black 5 can be used to print directly on cellulose fibre fabrics with good colorfastness and clear patterns.
Reactive Black 5 can be used for discharge printing as well, due to its ability to break the azo group under the influence of strong reducing agents. Printing with reducing agent can produce white or colored patterns.
