Basic Violet 7 (also known internationally as C.I. 48020 or Cationic Violet 16 / Red 2G analogs depending on market standards) represents a vital class of polymethine/cationic dyes famed for delivering peerless brilliance on polyacrylonitrile (acrylic) fibers, modacrylics, and cationic-dyeable polyesters. The chemical architecture depends on highly conjugated nitrogen-containing rings that optimize light absorption in the green spectrum, reflecting an intensely bright violet-to-pink shade.
Sunrise Chem is actively pioneering the shift away from traditional sodium-amalgam reduction steps and toxic solvents towards advanced green catalytic alkylation methods. By replacing halogenated organic solvents with eco-safe aqueous phase catalysts, we reduce our environmental load index by up to 45%. This advancement is critical to meeting the stringent restricted substance limits (RSLs) demanded by high-street apparel brands.
To eliminate inorganic salts that can impair solubility and build up in dyeing baths, Sunrise utilises advanced ultrafiltration membrane technology. This process produces high-purity crystalline powders and highly stable liquid forms. Microencapsulation technologies are also in development, designed to reduce dusting, prevent cross-contamination, and optimize solubility at lower temperatures.
By filtering out inorganic salts, we ensure excellent solubility and prevent scale build-up in high-velocity dyeing equipment.
Our modified molecular structures achieve over 95% dyestuff uptake, lowering wastewater COD/BOD levels for treatment plants.
Our formulation is free from banned arylamines and heavy metals, meeting ZDHC MRSL guidelines.
Cooperating with textile and paper mills for many years shows that the factory has established a strong and reliable business relationship. This kind of long-term collaboration can bring numerous benefits, such as consistent orders, shared resources, and mutual support. It also indicates that the factory has a good track record of delivering quality products and meeting the needs of its partners.
Our mission is to drive business growth by providing reliable and customized products. We aim to contribute to our customers' success by delivering first-class products and exceptional service. By building lasting partnerships, we strive to act as a catalyst for our clients' success.
Basic Violet 7 is the industry standard for dyeing acrylic fibers, yarn, and blends, offering brilliant colors and high lightfastness. Our formulations ensure level dyeing, avoiding color spots on delicate fabrics.
In the paper industry, Basic Violet 7 provides high-impact color for tissue, specialty packaging, and decorative papers. It is also compatible with water-soluble flexographic inks, offering fast drying times and stable rheological properties.
As supply chain volatility grows, Sunrise Chem has upgraded our facilities to align with Industry 4.0. Our factory utilizes closed-loop automated manufacturing systems where raw materials, reaction temperatures, pH levels, and drying processes are monitored by advanced sensors.
We work directly with key petrochemical manufacturers to secure reliable access to dye intermediates, insulating our partners from market shortages.
Our online spectrophotometric monitoring systems adjust color values during synthesis to maintain a color difference (Delta E) of less than 0.5 between batches.
We operate advanced biological wastewater treatment units alongside multi-stage evaporators to capture and recycle chemicals, minimizing our environmental footprint.
Environmental protection is the cornerstone of our innovation. We dedicate ourselves to providing eco-friendly, high-quality colorants that balance productivity with environmental harmony, driving the industry towards a more sustainable development path while delivering high-performance products—for a greener textile industry and a sustainable future.
With years of experience, we have successfully established strong partnerships in many countries. Our dedication to meeting global demands and exceeding customer expectations has earned us a reputation as a reliable supplier worldwide. If you are looking for reliable, high-quality Dyes, we invite you to choose us as your trusted partner.
The ZDHC program is a collaborative effort by leading brands, retailers, and suppliers in the textile and footwear industry to reduce the use of hazardous chemicals. The focus of this certification is on eliminating the release of hazardous chemicals into the environment throughout the entire supply chain. Achieving ZDHC certification indicates that our company has implemented robust chemical management procedures and has met the stringent requirements for chemical handling, wastewater treatment, and pollution prevention.
The Global Organic Textile Standard (GOTS) is a certification that ensures the organic status of textiles from the harvesting of raw materials to environmentally and socially responsible manufacturing. The GOTS certification guarantees that the textiles are made from organic fibers, that chemical inputs are minimized, and that strict environmental and labor standards are met throughout the production process. GOTS certified products are considered to be sustainable, safe, and ethical.
B2B chemical procurement requires strict attention to consistency, environmental compliance, and supply chain security. For purchasing directors sourcing Basic Violet 7, ensuring batch-to-batch uniformity is critical to avoiding variations in textile shading.
Sunrise Chem meets these requirements through rigorous quality management. Our analytical laboratories are equipped with HPLC and spectrophotometers to test dye parameters. We also offer tailored adjustments in color strength (e.g., 100%, 200%, 250% standard concentrations) to fit our clients' specific recipes.
Our chemical application engineers provide on-site technical support to help optimize textile bath parameters, matching colors to client substrates and advising on wastewater treatment.
We manage logistics and storage to ensure a stable supply of dyes, maintaining dynamic safety stocks for high-demand items to minimize delivery lead times.
Basic Violet 7 is a cationic dye engineered for acrylic and modacrylic fibers, offering excellent color strength, level exhaustion, and compatibility with other cationic dyes. It is also used in specialty paper sizing, decorative paper coatings, and writing inks.
We align with ZDHC Level 3 and hold GOTS certification. Our manufacturing plants utilize closed-loop systems to eliminate hazardous substances, ensuring compliance with REACH and other global environmental standards.
Yes, our lab uses spectrophotometric analysis to customize shade values, color strength, and physical form (powder or liquid) to match client specifications.
When stored in cool, dry, well-ventilated conditions in its original sealed packaging, Basic Violet 7 has a shelf life of up to 36 months. High humidity and direct sunlight should be avoided to prevent compaction.
Our automated process control maintains temperature deviations within ±0.5°C and pH within ±0.1 units during the synthesis reaction, keeping color variation (Delta E) below 0.5.
