Tianjin Sunrise Chem Group specializes in manufacturing high-quality dyestuffs. Our product portfolio includes Direct dyes, Acid dyes, Basic dyes, Sulphur dyes, Solvent dyes, Liquid dyes and Fluorescent dyes. Backed by decades of industry and export experience, we have built a solid reputation for reliability and excellence, serving clients from diverse global sectors including denim, textile, leather, paper, and plastics.
We highly focus on product quality and batch-to-batch stability. Each shipment undergoes rigid spectroscopic and chromatographical testing before transport to port. Adherence to strict regulatory guidelines like ZDHC Level 3 and GOTS (Global Organic Textile Standard) guarantees your environmental compliance and quality protection.
Environmental protection is the core catalyst of our chemical innovations. We are committed to providing our clients with eco-friendly, high-performance colorants that balance commercial productivity with ecological harmony, steering global textiles toward a greener, sustainable future.
A strategic technological blueprint evaluating molecular purity, structural synthesis, and environmental progress.
Basic Violet 13 (colloquially classified under triarylmethane dyes, related closely to C.I. 42535 / Methyl Violet 2B) has long served as a backbone dyestuff in global coloration systems due to its unmatched color intensity and high affinity for electronegative substrates. The molecular layout features a central sp2 carbon coordinated to three dialkylaminophenyl structures. Our technical roadmap focuses heavily on refining this synthesis path to eliminate residual heavy metal salts, such as zinc chloride double salts, which traditionally posed severe challenges for modern wastewater systems.
Sunrise engineers have developed a proprietary purification technology that replaces standard zinc crystallization with a green, crystallization-initiating organic acid process. This allows us to supply both a zinc-free crystalline salt format and a stable, highly concentrated liquid form, reducing heavy metal presence below international regulatory limits.
With carbon neutrality becoming a mandatory standard across textile supply networks, our engineering efforts focus on optimizing chemical oxygen demand (COD) and biochemical oxygen demand (BOD) loads in wastewater outputs. By optimizing the reaction yields using automated continuous-flow reactors, we minimize raw material wastage, decrease by-product formation by 42%, and ensure the resulting Basic Violet 13 powder displays outstanding solubility metrics (up to 80g/L in soft water) without requiring hazardous chemical dispersants.
How Sunrise tailors Basic Violet 13 configurations to meet targeted production demands across global industries.
Dyeing kinetics show high compatibility ($K$ value 3-4) on acrylic, modacrylic, and anionic modified polyester fibers. Delivers brilliant violet hues with high exhaustion rates and superior color-fastness.
Ideal for unbleached kraft pulp coloring. Basic Violet 13 exhibits high affinity for lignin, bonding directly to fibers without requiring heavy fixatives, ensuring clear backwater run-offs.
Extensively formulated in solvent-based marking pen inks, stamp pads, and ballpoint pens. Soluble in glycols, ketones, and alcohol media to create non-clogging, high-intensity writing fluid.
Cooperating with textile and paper mills for decades shows that the Sunrise factory has established a strong and reliable business relationship. This kind of long-term collaboration brings numerous benefits, such as consistent ordering, shared technical resources, and mutual troubleshooting support. It also indicates that the factory has a good track record of delivering quality products and meeting the challenging demands of its partners.
Our mission is to drive your business growth by providing reliable, customized color products. Our goal is to make a significant contribution to our customers' success by consistently delivering first-class products and exceptional customer service. By building lasting partnerships, we strive to be a catalyst for our clients' success.
How our advanced industrial infrastructure ensures reliable production and consistent supply in a volatile global economy.
One of the primary reasons global customers choose Sunrise is our highly stable supply of dyes. We have developed efficient manufacturing processes to ensure a continuous supply of our products. Our factories feature state-of-the-art equipment, DCS (Distributed Control Systems), and a highly trained workforce, which enables us to fulfill the most demanding industrial orders. With Sunrise, you can begin your manufacturing journey with confidence, knowing that dye availability will never be a bottleneck.
Our experienced chemical technicians carefully monitor the manufacturing process, ensuring that each batch of dyes is tested for color fastness, solubility, and other essential parameters. By choosing Sunrise, you can rest assured that your products will stand out in the market due to the vibrant, long-lasting color our dyes provide.
In addition to manufacturing, we manage a strategic logistics network. Based close to Tianjin Port, one of North China's largest shipping gateways, we minimize land transport times and optimize container loading procedures. This logistics speed ensures that global clients receive their consignments quickly, keeping warehouse levels lean and supply operations smooth.

Addressing supply chain risks, regulatory hurdles, and ecological expectations in international markets.
The ZDHC (Zero Discharge of Hazardous Chemicals) program is a collaborative effort by leading global brands, retailers, and chemical suppliers in the textile and footwear industry to reduce the use of hazardous substances. Achieving ZDHC Level 3 certification indicates that Sunrise has implemented robust chemical management procedures, and meets the most stringent requirements for handling, wastewater purification, and pollution prevention.
Additionally, the Global Organic Textile Standard (GOTS) certification ensures the organic status of textile products from raw material harvesting through environmentally and socially responsible manufacturing. The GOTS standard guarantees that chemical inputs are minimized, and strict environmental and labor protocols are observed throughout the production pipeline.
Both certifications are critical benchmarks in modern, responsible textile manufacturing. While ZDHC focuses on removing harmful chemical outputs, GOTS guarantees organic integrity and ethical manufacturing, providing a solid foundation for your green supply chain.
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. Our dedicated technical support team works directly with your dyehouse technicians to formulate custom recipes, optimize exhaustion parameters, and provide in-person troubleshooting if color anomalies occur. By integrating localized support nodes across key hubs in Southeast Asia, Europe, and Latin America, Sunrise helps minimize production bottlenecks and ensures seamless technical coordination.
