Explore our premium selection of dyes, synthetic colorants, and heavy-duty formulations engineered for textile, paper, and industrial applications.
Tianjin Sunrise Chem Group stands at the forefront of the global chemical synthesis sector, specializing in the research, optimization, and mass-scale manufacturing of high-quality dyestuffs. Our product portfolio spans 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 an unyielding reputation for reliability and excellence, serving global clients from diverse sectors including denim finishing, textile processing, leather tanning, paper mills, and industrial plastics formulation.
Our operational philosophy is anchored on two pillars: quality stability and technological innovation. Every batch undergoes strict chromatography and spectrophotometric testing before shipment, ensuring absolute color consistency. With certifications including ZDHC Level 3 and GOTS (Global Organic Textile Standard), Sunrise Chem guarantees compliance with the world's most demanding environmental and toxicity standards.
Sulphur Black BR (specifically C.I. Sulphur Black 1) remains the absolute anchor colorant for denim cotton warp yarn dyeing and heavy cotton fabrics globally. B2B buyers face shifting market dynamics: environmental regulations are restricting low-end, high-sulfur crude alternatives, while demand for deep, carbon-neutral blacks continues to rise.
Our long-term collaboration with major textile and paper mills worldwide is a testament to the stability of our chemical formulations. Long-term partnerships deliver mutual advantages: consistent supply forecasting, optimized bath configurations, and custom adjustments for shade variations. Our core mission is to empower textile processors with dyes that ensure optimal fastness while reducing chemical oxygen demand (COD) in wastewater treatment plants.
Delivering advanced application engineering for continuous dyeing machines, rope dyeing lines, and exhaust dyeing setups.
Our Sulphur Black BR is engineered to ensure excellent affinity and penetration in continuous rope and slasher dyeing lines. By controlling the oxidation speed and pH levels, we prevent bronzing defects and achieve deep, uniform shades of black across millions of meters of yarn.
Sunrise provides specialized liquid direct and sulphur formulations designed for rapid fixation on cellulose fibers. These solutions prevent bleeding and improve the mechanical strength of colored kraft papers and heavy-duty packaging boards.
For bovine and synthetic leathers, our acid and basic dye ranges guarantee deep penetration through the collagen matrix. The results are highly saturated tones, excellent lightfastness, and compatibility with modern polyurethane and acrylic coatings.

We do not just produce and export dyes and pigments; we prioritize long-term cooperation with our B2B customers, providing them with technical services that exceed their expectations. Our manufacturing processes are continually optimized to ensure a steady supply of dyes, even during periods of raw material volatility.
Our plants are equipped with modern synthesis reactors, automated spray dryers, and standardization blenders. Every batch is measured against a standard master batch to maintain color strength tolerances within 2%. By choosing Sunrise Chem, you can plan your production cycles with confidence, knowing that supply delays and color variations are minimized.
The Zero Discharge of Hazardous Chemicals (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. Achieving ZDHC Level 3 certification—the highest level in the program—indicates that our chemical formulations comply with the manufacturing restricted substances list (MRSL) and do not contain intentionally added hazardous chemicals.
Additionally, our GOTS (Global Organic Textile Standard) certification guarantees that our colorants can be used in organic textile manufacturing. GOTS ensures the organic status of textiles from the harvesting of raw materials to environmentally and socially responsible manufacturing. By partnering with Sunrise, you gain access to colorants that help you meet environmental audits, lower wastewater treatment costs, and satisfy eco-conscious consumers.

Our standard Sulphur Black BR (C.I. Sulphur Black 1) is typically supplied at 200% to 240% concentration relative to the international standard. We can also customize the strength to meet specific formula requirements for your dyeing processes.
Our quality control lab tests every production run using computerized spectrophotometers. We keep standard master batches on file and verify that new shipments have a color variance (Delta E) of less than 0.5 before dispatch.
Sodium sulfide (Na2S) is the standard reducing agent used to solubilize the dye. In eco-certified mills, glucose-based reducing systems or sodium hydrosulfite can also be used, depending on the machine setup and wastewater limits.
Yes, our Sulphur Black BR is certified to ZDHC Level 3. This indicates that our products do not contain intentionally added hazardous chemicals on the ZDHC MRSL list, helping you meet strict brand audits.
Sulphur Black BR powder has a shelf life of up to 3 years when stored in a cool, dry place in its original sealed packaging. Liquid sulphur dyes are typically stable for 1 year and should be protected from freezing temperatures.
Our facility in Tianjin, close to Xingang port, allows us to coordinate shipping logistics efficiently. We offer bulk options, including 25kg bags, 500kg jumbo bags, and custom drum configurations to fit your mill's handling equipment.
A majority of our direct, acid, and sulphur dyes are approved under the Global Organic Textile Standard (GOTS). This allows them to be used in the processing of certified organic cotton and natural fibers.
Bronzing is usually caused by premature dye oxidation on the fabric surface. This can be prevented by maintaining proper dye bath alkalinity, keeping temperature controls consistent, and rinsing thoroughly before the oxidation step.
Yes. We can supply our dyes as free-flowing, low-dust granules, standard powders, or pre-reduced liquids to ensure compatibility with your factory's automated weighing and dispensing systems.
Yes, our lab team can perform color matching. You can send us a substrate sample and target shade, and we will formulate a recipe using our dyes to match your specifications for fastness and tone.
