As a global leader in high-performance dyestuffs, Tianjin Sunrise Chem Group specializes in the R&D and precision manufacturing of industrial colorants. Our expansive synthesis capabilities yield a comprehensive catalog featuring Direct dyes, Acid dyes, Basic dyes, Sulphur dyes, Solvent dyes, Liquid dyes, and Fluorescent dyes.
Backed by decades of industrial manufacturing and export excellence, we have established an unyielding reputation for reliability. We support critical chemical processes for multi-national players across the denim, textile, leather, paper, and plastic sectors. Quality control and color consistency form the core of our operations; hence, every single batch undergoes rigorous spectrophotometric evaluation prior to port dispatch.
Importantly, our facilities operate at the vanguard of environmental safety. By securing ZDHC Level 3 and GOTS (Global Organic Textile Standard) certifications, we ensure that our supply chain mitigates harmful effluent discharge, aligning your procurement with stringent modern environmental codes.
Direct Blue 108 is an anionic copper-complex phthalocyanine or polyazo dyestuff designed specifically for high affinity towards cellulosic matrices. The molecular design incorporates multiple sulfonic acid functional groups, which grant excellent water solubility. This structural formation ensures steady diffusion into raw cotton, linen, viscose, and kraft paper fibers during exhaust dyeing processes.
The chemical bonding mechanism of Direct Blue 108 relies on a combination of hydrogen bonding and Van der Waals forces, aligning within the amorphous zones of cellulose fibers. To assist design engineers and procurement officers, the exact specifications and colorfastness data are summarized in the industrial matrix below:
| Technical Parameter | Standard Specification Value | Testing Protocol |
|---|---|---|
| Chemical Class | Azo / Copper Complex Direct Dye | Chromatographic Analysis | CAS Registry Number | 1324-58-9 / 61725-05-1 | CAS Index Registry |
| Physical Appearance | Uniform Deep Blue Powder / Granules | Visual Quality Control |
| Water Solubility | ≥ 40 g/L (at 90°C) | Gravimetric Method |
| Lightfastness (ISO 105-B02) | Grade 5 - 6 | Xenon Arc Lamp Exposure |
| Washfastness (ISO 105-C06) | Grade 3 - 4 (Medium Fixation) | Mechanical Laundering Test |
| Acid / Alkali Resistance | Grade 4 (Highly Stable) | Chemical Reactivity Test |
In the contemporary global chemical market, raw material price volatility and strict eco-audits challenge the continuity of manufacturing plants. At Sunrise Chem, we solve these supply challenges through backward integration. By securing crucial intermediates and executing lean synthesis methods, we ensure a stable, year-round dye supply regardless of local environmental shutdowns or global logistics disruptions.
Our long-term partnerships with leading textile mills, paper manufacturers, and leather tanneries highlight our capabilities. Sunrise Chem does not simply act as a merchant vendor; we function as a strategic growth catalyst, aligning product consistency, regulatory compliance, and cost-efficiency to fortify our clients' market positions.
We integrate cutting-edge science and global compliance parameters to supply high-purity dyestuffs that elevate yield efficiency.
Features superior salt-controlled kinetics ensuring outstanding migration behavior, avoiding blockages, dye spots, and uneven shade distribution in high-capacity continuous dyeing machinery.
Complies directly with strict environmental limits for restricted substances, keeping heavy metals, free aromatic amines, and hazardous chemical residuals far below GOTS thresholds.
Optimized for liquid blending and powder dissolution, Direct Blue 108 shows excellent compatibility with common industrial sizing agents, fixing agents, and anti-crease resins.
Direct Blue 108 is engineered to perform reliably across a variety of substrates. Our specialized applications deliver predictable, outstanding results under harsh conditions.
Applied via exhaust and pad-batch dyeing methods on cotton yarn, knitwear, and woven fabrics. Exhibits high exhaustion rates at medium to high temperatures (80°C - 90°C), resulting in deep, rich blue shades that withstand repeated domestic laundering cycles.
Perfect for raw pulp staining, sizing press coloring, and surface coatings of paperboards. Demonstrates rapid affinity to unbleached and bleached kraft fibers, producing clear, non-bleeding blue shades suitable for high-end packaging paper.
Exhibits uniform penetration across chrome-tanned and vegetable-tanned leather structures. Sunrise Chem's Direct Blue 108 guarantees excellent surface coverage without cracking or bronzing, preserving the natural soft hand of premium leather products.
Modern chemistry demands ecological accountability. The global textile supply chain operates under intense environmental scrutiny. Tianjin Sunrise Chem Group meets this challenge proactively. Our manufacturing sites are built on advanced clean-production principles, utilizing closed-loop wastewater recovery systems to isolate, neutralize, and safely dispose of synthesis byproducts.
By complying with the ZDHC (Zero Discharge of Hazardous Chemicals) Program Level 3, we certify that our formulation recipes exclude restricted alkylphenol ethoxylates (APEOs), formaldehydes, and hazardous heavy metals. Additionally, our GOTS certification guarantees that all raw materials are traceable, clean, and ethically processed, helping brands capture green markets worldwide.
We coordinate shipments efficiently across several continents, guaranteeing safe packing and rapid dispatch times.
Looking ahead, Tianjin Sunrise Chem is investing heavily in smart color chemistry. Our R&D division focuses on reducing salt consumption during exhaustion processes. By modifying the chemical structure of direct dyes like Direct Blue 108, we aim to increase exhaustion levels to over 95%, dramatically cutting downstream COD and BOD treatment costs for textile mills.
In addition, we are exploring enzymatic washing processes and bio-based raw intermediates. Replacing petroleum-derived synthesis blocks with renewable carbon sources allows us to provide high-purity industrial dyes with a drastically reduced carbon footprint. Partner with Sunrise Chem to secure cutting-edge, sustainable solutions that protect your profits and the planet.
