Product Description
Reactive Black HN Reactive Black 8 is a printing dye of good light fastness as well as washing fastness. It gives a sort of gray tint in lighter shade. This is accessible with good solubility and is accessible with long life stability. It has strong colouring property and can be added in a diluted solution. Reactive Black HN Reactive Black 8 is suited for the cotton, linen, silk, viscose, polyamide fiber and wool dyeing process. This is apt for the direct printing.
Key Points:
- It is functional as the most widely used reactive dye that performs the textile finishing.
- It is a diazo dye, which can be decolorized via facultative anaerobic bacteria
- It is also apt for the coloring for wool as well as polyamide
- It helps in the biodegradation of RB5-containing wastes.
Superior Performance for Textile Applications
Reactive Black HN delivers deep, uniform black shades with reliable, high tinctorial strength and resistance to water, washing, and light. Its anionic nature ensures excellent compatibility with natural fibers and optimal fixation when using sodium carbonate. Textile industries benefit from its stability in neutral to slightly alkaline pH environments.
Eco-Friendly Compliance
Committed to sustainable production, Reactive Black HN is azo-free and meets REACH regulatory standards. This makes it a responsible choice for manufacturers concerned about environmental impact and consumer safety, further backed by its non-hazardous transport classification.
Flexible and Efficient Usage
With its fine powder form and high purity of 99%, Reactive Black HN is easy to measure and disperse, allowing precise dosage control. Its compatibility with other dyes supports creative shading possibilities while ensuring consistent, vibrant results across diverse textile materials.
FAQ's of Reactive Black HN Reactive Black - 8:
Q: How do I use Reactive Black HN Reactive Black - 8 for dyeing textiles?
A: To dye textiles with Reactive Black HN, dissolve the fine powder in water, maintain a neutral to slightly alkaline pH (7-8), and use sodium carbonate as the recommended fixation agent. Adjust the dosage according to desired shade intensity and ensure even distribution for uniform coloring.Q: What types of fibers can Reactive Black HN be applied to?
A: Reactive Black HN is versatile and suitable for dyeing cotton, viscose, wool, and silk. Its high tinctorial strength ensures long-lasting, intense black shades on both cellulosic and protein-based fibers.Q: When should I use sodium carbonate during the dyeing process?
A: Sodium carbonate should be added after dissolving the dye and wetting the fibers, as it acts as the fixation agent. Introducing sodium carbonate helps bond the dye to the textile molecules, optimizing color durability and wash fastness.Q: Where should Reactive Black HN be stored?
A: This dye must be stored in a cool, dry place in its original HDPE bags or cartons. Proper storage will preserve its quality, prevent moisture absorption, and uphold its 2-year shelf life.Q: What benefits does Reactive Black HN offer in textile manufacturing?
A: Manufacturers gain consistent, eco-friendly, and deep black coloration with excellent wash and light fastness. The dye's easy solubility, compatibility with other dyes, and odorless profile further improve operational efficiency and worker safety.Q: Is Reactive Black HN compatible with other dyes for shaded effects?
A: Yes, Reactive Black HN is chemically compatible with other reactive dyes. This allows for customized shading and unique color blends to meet specific design requirements and customer preferences.Q: What distinguishes Reactive Black HN as an eco-friendly choice for textile dyeing?
A: Reactive Black HN is azo-free and complies with REACH guidelines, ensuring minimal environmental impact and increased safety for end users. Its non-toxic, non-hazardous classification makes it suitable for responsible manufacturing practices.Tell us about your requirement
