Discover our highly stable synthetic organic dyes engineered for rigorous industrial demands and environmental compliance.
In modern global manufacturing, Sulphur Dyes represent the cornerstone of cost-effective, high-fastness coloration, particularly in denim and heavy-duty cotton fabrics. As global regulatory bodies impose tighter limits on chemical emissions, the demand for high-purity, environmentally compliant OEM sulphur dyestuffs has surged.
At SUNRISE, we bridge the gap between traditional chemical stability and modern ecological requirements. Standard sulphur dyestuffs often carry high concentrations of free sulfides and heavy metal impurities. Through our innovative synthesis and purification routes, we provide OEM dye solutions that significantly reduce ecological footprints, making them ideal for Tier-1 textile brands aiming for strict wastewater conformance.
Our manufacturing processes focus on reducing the reliance on aggressive reducing agents. By offering optimized leuco-liquid forms alongside standard powder options, we allow mills to minimize water consumption, standardize color yields, and guarantee batch-to-batch consistency.
Decades of synthesis expertise delivering premium Direct, Acid, Basic, Sulphur, and Fluorescent dyes.
Tianjin Sunrise Chem Group specializes in manufacturing high-quality dyestuffs. Our comprehensive color 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 an international reputation for reliability and excellence, serving clients from diverse sectors including denim, textile, leather, paper, and plastics.
We prioritize quality control and stability above all. Every batch of dyestuff undergoes strict testing prior to port delivery, ensuring that physical properties, tinctorial strength, and chemical components match technical requirements. Our ZDHC Level 3 and GOTS certificates provide our clients with solid quality assurance.
We pride ourselves on offering customized OEM solutions. Our technical teams work closely with global mill operators to deliver tailored concentrations, dust-free granules, and customized liquid dyes that improve batch efficiency.

Highly concentrated azo dye formulated for vibrant reds in wool, nylon, and blended synthetic textiles. Optimized for uniform levelness and high wet-fastness ratings under demanding commercial wash tests.
Meeting the strict requirements of ZDHC Level 3, GOTS, and international zero-discharge guidelines.
For contemporary garment manufacturers, compliance is just as critical as color precision. The textile industry has shifted away from suppliers that cannot verify their environmental footprint. By manufacturing dye formulations that adhere to the Zero Discharge of Hazardous Chemicals (ZDHC) program and the Global Organic Textile Standard (GOTS), SUNRISE helps ensure that your finished products comply with global retail restrictions.
Our ZDHC Level 3 status confirms that our production processes, raw materials, and chemical inventory have been independently audited to eliminate the use of hazardous substances. This helps reduce wastewater treatment loads at customer dyeing facilities.
The Global Organic Textile Standard (GOTS) certification ensures that our chemical inputs meet organic processing standards. This enables dyehouses to process organic cotton under certified chain-of-custody requirements.
We screen for banned aromatic amines, heavy metal content, and free formaldehyde, ensuring safe export handling and helping to prevent costly batch rejections at destination ports.
Consistent production capacity and secure logistics operations optimized for international sea and rail transit.
At SUNRISE, we do more than just manufacture dyes and pigments. We prioritize building reliable, long-term partnerships by providing services that meet our clients' logistical needs. Secure product packaging, containerization, and warehouse storage are critical to preventing moisture absorption and oxidation of sulphur and direct dyestuffs.
Our modern factory features state-of-the-art synthesis lines, mechanical filter presses, and automated spray-drying towers. This infrastructure ensures uniform particle size distributions, helping to eliminate dusting issues in the dyehouse kitchen. Our proximity to major shipping terminals ensures container availability and prompt port delivery.
Our customer support teams assist with customs clearance, certificate of analysis (COA) documentation, and shipping schedules, facilitating hassle-free border clearance.
How Sunrise is adapting synthesis strategies to meet the requirements of low-emission processing.
Traditional sulphur dyeing relies on sodium sulfide as a reducing agent, which can generate hydrogen sulfide gas in effluent streams. To address this, SUNRISE is focused on two main development paths:
By investing in these technological shifts, we help global mills prepare for stricter environmental regulations while maintaining high coloration performance.
Tailored packing, customized formulation concentrations, and full technical documentation support.
We collaborate with chemical distributors and large-scale textile mills to establish reliable OEM channels. Our customizable solutions include:
Adjustable Active Content: We calibrate dye concentration percentages to match specific cost and application requirements.
Custom Formulations: We offer customizable liquid-to-powder ratios, micro-granule options, and specialized anti-dusting agents to suit diverse dyehouse equipment.
White-Label Packaging: We provide customizable labeling and packaging sizes, ranging from 25kg bags to bulk IBC containers.
Our experienced customer support team is available to address any questions, provide safety datasheets (SDS), and assist in resolving technical challenges.
Expert technical answers to common questions regarding formulation, usage, and logistics.
