High-purity organic and inorganic coloring formulas engineered for precision textile, paper, leather, and plastic applications.
The global dyestuff and pigments industry serves as a crucial backbone for modern manufacturing, playing a key role in the aesthetic and functional properties of textiles, leather, paper, plastics, and specialized chemical coatings. With rapid industrialization and shifting consumer demands, the global commercial volume of dyestuffs continues to grow, driven by advances in textile engineering, packaging paper dynamics, and high-performance polymer coloration. Today's commercial ecosystem demands more than just vibrant colorants; it requires suppliers who can deliver absolute batch-to-batch consistency, deep technical customization, and strict compliance with ecological safety regulations.
As a leading OEM Dyes manufacturer and supplier, Tianjin Sunrise Chem Group bridges the gap between scientific color synthesis and heavy industrial applications. In a market where supply chain resilience is paramount, OEM dye formulation has transformed from basic toll processing to complex co-development. Modern global operations require localized application intelligence to handle challenges such as water hardness variance in regional textile mills, varying fiber affinity in cellulose pulp, and thermal stability requirements in polymer extrusion. The capability to synthesize customized Direct, Acid, Basic, Sulphur, Solvent, and Liquid Dyes marks the transition of a supplier from a raw material provider to a strategic growth partner.
Tianjin Sunrise Chem Group specializes in the development, manufacturing, and export of premium-grade dyestuffs. Our product portfolio spans a comprehensive array of colorant classes including Direct Dyes, Acid Dyes, Basic Dyes, Sulphur Dyes, Solvent Dyes, Liquid Dyes, and Fluorescent Dyes. With decades of industry and export experience, Sunrise has built a reputation for reliability and excellence, serving clients from diverse sectors including denim finishing, commercial textiles, leather tanning, paper mills, and industrial plastics. We prioritize product stability and quality above all else; each shipment undergoes rigorous quality assurance testing before leaving our port. Our ZDHC Level 3 and GOTS certifications ensure that our partners can operate in compliance with strict ecological regulations.
At Sunrise, we understand that off-the-shelf color formulations do not always meet the unique physical and chemical challenges of advanced production systems. Our team of experts works closely with partners to develop customized solutions, tailoring chemical concentrations, physical states, and dispersion behaviors to match specific application setups. By seeking strategic global partnerships, we continue to expand our reach, offering mutual growth opportunities to mills, chemical distributors, and manufacturing enterprises worldwide.
Environmental protection is a key driver of modern color chemistry. The global textile, footwear, and paper industries are under continuous scrutiny from regulatory bodies and consumer groups demanding cleaner production cycles. This shift has changed the criteria for selecting chemical suppliers. Achieving ZDHC Level 3 certification (Zero Discharge of Hazardous Chemicals) is a key validator of chemical safety. It confirms that the supplier's chemical formulations do not intentionally contain substances listed on the ZDHC Manufacturing Restricted Substances List (MRSL), ensuring compliance from raw material procurement through chemical synthesis to final packaging.
Verifies that all chemical formulations and processes avoid intentional use of MRSL-restricted substances, helping protect wastewater streams and local environments.
Guarantees the organic status of textile components from harvesting through environmentally and socially responsible manufacturing practices.
Delivers high-performance color fastness and brilliance while reducing the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) of discharge.
Complementing this is the Global Organic Textile Standard (GOTS), which ensures the organic integrity of textiles at all stages of production. GOTS-compliant dyes must meet strict criteria regarding toxicity, biodegradability, and heavy metal concentrations. By aligning our production with GOTS and ZDHC Level 3, Sunrise assists downstream partners in meeting strict corporate social responsibility (CSR) targets. This commitment supports clean wastewater management, reduces environmental impact, and provides our customers with reliable, compliant products for a sustainable market.
Industrial dyeing requires customized solutions tailored to specific fiber chemistry, substrate characteristics, and process technologies. Sunrise addresses these requirements across multiple industrial applications:
Sulphur dyes remain the standard for authentic denim wash-downs and deep black shades. Sunrise’s Sulphur Black Crystal and Liquid formulations provide excellent solubility and reduction potential. They offer deep penetration into cotton fibers while maintaining the wash-fastness required for modern enzymatic and ozone stone-washing techniques.
High-speed papermaking requires rapid color exhaustion and clean backwater properties. Liquid formulations, such as Liquid Direct Yellow R and Basic Violet 1, offer easy handling and dust-free operations. They help prevent specking, improve shade consistency across paper webs, and minimize cleaning downtime during product transitions.
Leather applications require excellent solvent solubility and leather-grain penetration, criteria met by Solvent Black 34 and Solvent Black 5. For plastic applications, such as in Iron Oxide Black 27, thermal stability is critical. Our inorganic pigment selections resist decomposition at temperatures up to 260°C, maintaining polymer integrity and color stability during extrusion.

The industrial dyestuff industry is moving towards cleaner chemistry, digital color matching, and raw material circularity. Sunrise's technology roadmap focuses on developing bio-based dye intermediates to reduce reliance on petrochemical inputs. We are investigating bio-derived aromatics to synthesize dyes that deliver equivalent tinting strength and fastness properties to traditional formulas.
A major focus of our research and development is minimizing water consumption. In traditional exhaust dyeing, the water footprint can be significant. By adjusting the molecular structure of our direct and acid dyes, we aim to increase the dye exhaustion rate (exhaustion value $E > 95\%$), minimizing residual color in the effluent. Additionally, we are expanding our liquid dye technologies. Liquid dyes eliminate the dust hazards associated with powder dyes, improving work environment safety while supporting automatic metering systems in paper and textile mills. This approach helps reduce errors, conserve resources, and lower the overall carbon footprint of coloring operations.
Fulfilling bulk contracts requires efficient logistics management alongside reliable chemical synthesis. Over decades, Sunrise has established a robust distribution network. We work closely with chemical freight forwarders to ensure that hazardous and non-hazardous dyestuffs are packaged, labeled, and shipped in compliance with international maritime laws.
Whether managing container loading for large shipments of Sulphur Black or transporting stabilized liquid colorants, our logistics team coordinates closely with port authorities. We provide all necessary documentation, including Safety Data Sheets (SDS), Certificates of Analysis (CoA), and ecological certifications. Our structured warehousing ensures inventory is stored under temperature-controlled, moisture-free conditions, preventing degradation and guaranteeing that the chemical properties of our products remain stable upon arrival.
