Our comprehensive color portfolio includes Direct Dyes, Acid Dyes, Basic Dyes, Sulphur Dyes, Solvent Dyes, Liquid Dyes, and Fluorescent Dyes. Engineered to serve diverse industrial sectors—from premium textiles, denims, and leathers to paper pulp and technical plastics—we ensure that every batch exhibits brilliant shade consistency, excellent fastness properties, and optimized dissolution behaviors.
With decades of specialized synthesis and export experience, Sunrise Chem Group has built an international reputation for unmatched quality. We support global brands as a trusted OEM manufacturer, translating complex color requirements into robust, sustainable chemical solutions. Rather than offering basic off-the-shelf colorants, we cooperate deeply with technical mills to customize formulations for modern machinery, fast-cycling dyeing baths, and stringent ecological requirements.
A technical guide on how Sunrise Chem Group synthesizes high-performance acid colorants for wool, silk, polyamide (nylon), and leather substrates.
Acid dyes are water-soluble anionic dyestuffs containing one or more sulfonic acid (—SO₃H) or carboxylic acid groups that form ionic bonds with the protonated amino groups of protein and polyamide fibers in an acidic bath. As a leading OEM acid dye brands manufacturer, Sunrise Chem Group leverages deep molecular synthesis capabilities to supply dyes optimized for leveling, migration, and build-up behaviors.
Formulated with smaller molecular structures, these dyes display outstanding migration and leveling capability even on uneven substrates. Ideal for fine wool knitwear, silk fabrics, and light-shade nylon, where absolute visual uniformity is paramount. Requires precise pH control between 4.0 and 5.5.
Synthesized with larger, aromatic hydrophobic groups, milling dyes yield excellent wet fastness properties with medium leveling characteristics. They are highly responsive to auxiliary agents and exhibit high affinity for natural fibers, making them the preferred choice for heavy woolens and blanket fabrics.
Incorporating a metal atom (usually chromium or cobalt) within the dye molecule, 1:2 metal complex dyes provide the ultimate level of light, washing, and perspiration fastness. Widely utilized in premium automotive upholstery, durable nylon carpets, outdoor apparel, and heavy-duty leather products.
Our long-term partnerships with leading textile, leather, and paper mills globally demonstrate Sunrise Chem Group’s robust supply capabilities. China represents the epicenter of chemical synthesis infrastructure. By locating our key production nodes in industrial zones near major ports, we secure unbeatable logistical advantages, consistent raw material availability, and highly optimized processing economics that we pass directly to our OEM brand partners.
Our vertical integration enables us to control the synthesis pathway from intermediate precursors right down to the finished spray-dried powder or standardized liquid solution. This strict control insulates our global buyers from market volatility, raw material shortages, and inconsistent dye strengths. With Sunrise Chem Group, you gain a partner capable of keeping your production lines active, regardless of macro-level supply disruptions.
Navigating the complex landscape of international chemical compliance to ensure friction-free product imports and consumer safety.
For multinational corporations and global fashion brands, procuring chemical dyestuffs involves strict adherence to health, safety, and environmental guidelines. Uncertified dyes containing banned arylamines, heavy metal impurities, or restricted alkylphenol ethoxylates (APEOs) present severe financial and reputational risks. That is why Sunrise Chem Group enforces a zero-compromise approach to ecological compliance.
We are a certified ZDHC Level 3 manufacturer, meaning our formulations have been tested and registered on the ZDHC Gateway to ensure they conform to the stringent requirements of the Manufacturing Restricted Substances List (MRSL). This represents the highest level of assurance in the textile industry, verifying that restricted chemicals are not used during the chemical synthesis stages.
Furthermore, our GOTS (Global Organic Textile Standard) certificate guarantees that our colorants are approved for use in organic textile processing. GOTS certified products are monitored for environmental management, social responsibility, and low ecotoxicity, ensuring your end products can confidently carry organic credentials.

Modern printing and dyeing enterprises operate under intense regulatory scrutiny. Whether it is compliance with the EU REACH registration system, handling regional wastewater restrictions in Central America, or ensuring skin-contact safety for garments sold in North America, we provide direct local technical and regulatory assistance. Our chemists collaborate closely with regional distributors to offer on-site trials, troubleshoot bath exhaustion levels, and optimize recipes for maximum dye fixation, which drastically reduces environmental load.
Chemical sustainability is not just a regulatory hurdle; it is the cornerstone of our continuous innovation. We dedicate ourselves to supplying green colorants that strike the perfect balance between vibrant color yields and minimal environmental impact. Our research team focuses on developing low-salt dye structures, metal-free acid colorants, and ready-to-use liquid alternatives that reduce water usage during dye-bath rinsing cycles.
Our goal is to build long-term business relationships based on absolute trust and mutual benefits. By providing customized OEM branding solutions, we help chemical distributors, wholesalers, and private labels design their product lines. From specific color shade strengths (ranging from 100% standard to 200% super-concentrated formulations) to specialized dust-free granulate shapes, we customize our manufacturing to align with your business goals.
Furthermore, we support eco-conscious brands looking to implement complete circular manufacturing. By providing full lifecycle documentation, raw material certificates, and analytical test reports for each batch of dyes, we help our partners complete third-party audits seamlessly.

Expert insights regarding the application, storage, customization, and environmental compliance of industrial acid dyestuffs.
The primary differences lie in molecular size, level of sulfonation, and affinity. Leveling dyes have small molecular weights and high sulfonation, making them highly soluble and capable of excellent migration, though they have moderate wet fastness. Milling and supermilling dyes have larger structures, lower sulfonation, higher affinity, and superior wash fastness, but require tighter pH control (higher acidity) to prevent uneven dyeing.
ZDHC Level 3 is the highest chemical safety certification level. It means the dyestuff formulation has been independently audited and tested to verify it does not contain any restricted substances defined in the ZDHC MRSL. This minimizes environmental risk in wastewater and protects consumers, ensuring the dyestuff is safe for import to Europe, North America, and other regulated markets.
Yes. As a primary OEM manufacturer, we offer standard concentration levels (such as 100% or 150%) as well as custom highly concentrated versions. For liquid dyes, we can adjust the formulation’s viscosity, density, and pH to match the specifications of automated injection systems and industrial textile printing lines.
We use state-of-the-art spectrophotometric analysis (such as Datacolor systems) to test every batch against international standards. High-performance liquid chromatography (HPLC) is employed to monitor chemical purity. A shipment is released for export only after the Delta E color difference values fall below 0.5 compared to the master standard.
We support various packaging standards, including 25kg iron drums, carton boxes, woven sacks, and 500kg to 1000kg bulk bags. For liquid colorants, we provide sealed HDPE drums and IBC totes. Customized labels, barcodes, and private branding are available upon request.
Dyes should be stored in a cool, dry, and well-ventilated warehouse, kept away from direct sunlight, moisture, and high heat. Ensuring drums remain tightly sealed when not in use prevents powder clumping and helps retain optimal dye solubility over a long shelf life.
