High-purity chemical dyes engineered for consistent performance across textile, paper, and industrial sectors.
Understanding the technical necessity, market placement, and industrial value of Cationic Red X-GRL (Basic Red 46).
Basic Red 46, systematically known in chemical engineering circles as Cationic Red X-GRL, is a crucial synthetic monoazo dye characterized by its phenomenal binding capabilities on acrylic, modacrylic, and cationic-dyeable polyester (CDP) fibers. As a highly vibrant dye, it acts as the primary component in creating rich reds, brilliant pinks, and deep burgundy shades when formulated alongside basic yellow and blue elements.
Globally, the demand for Basic Red 46 has surged. This is heavily driven by the expanding consumption of acrylic yarns, blankets, high-performance sportswear, and knitwear. Modern consumer preference dictates textiles that resist fading through numerous washes and withstand extreme exposure to sunlight. Basic Red 46 meets these strict parameters due to its structural affinity to the negatively charged acid groups embedded inside the molecular makeup of acrylic polymers.
As leading global brands transition away from low-durability pigments, professional dyers require manufacturers who can supply Basic Red 46 that is free from toxic impurities. Understanding this shift, Tianjin Sunrise Chem Group utilizes precise synthesis methods to limit non-functional salts and heavy metals, offering superior solubility and reliable exhaustion metrics for large-scale operations.

We dedicate ourselves to supplying clients with eco-friendly, high-performance colorants that balance manufacturing efficiency with environmental harmony. We strive to drive the global dyestuff industry towards a more sustainable development path, creating a greener textile sector and a more sustainable future.
Tailoring dye characteristics to specific regional substrate requirements and industrial application methods.
Applied extensively in major textile hubs for coloring acrylic yarns, socks, and sweaters. It utilizes precise temperature-controlled exhaustion phases to ensure excellent level dyeing on acrylic hanks and package-dyed yarns, preventing color-strike at critical temperatures.
Used widely for technical fabrics requiring flame retardancy, such as modacrylic/cotton or modacrylic/polyester blends. Basic Red 46 preserves structural fibers while delivering deep, uniform red hues with minimal thermal migration under harsh conditions.
Specially formulated in liquid form or high-solubility powders for paper mills. Excellent compatibility with sizing agents and starches allows the colorant to be added directly to the pulp slurry, resulting in bright red packaging boards and specialty cardstocks.
Because cationic dyes have a high affinity for acrylic fibers, they tend to dye rapidly once the temperature reaches the glass transition state (Tg, approx. 80°C). Our engineers recommend using a high-performance cationic retarder (such as 1227 or trimethyl benzyl ammonium chloride) and keeping the heating rate at exactly 0.5°C to 1°C per minute between 80°C and 98°C to prevent unlevel dye spots and optimize fastness ratings.
Pioneering green synthesis processes and advanced molecular optimization to meet the strict demands of the future.
Replacing traditional heavy-metal catalysts in the azo-coupling reaction stage. Our R&D is focused on organic green catalysts to guarantee zero hazardous by-products, ensuring compliance with future ecological updates.
Modifying Cationic Red molecular branches to lower the thermal energy barrier. This allows for rapid bonding at 85°C–90°C instead of boiling, helping textile mills reduce fuel and energy costs.
Transitioning from fine crystalline powders to micro-granular structures. This minimizes dust in handling areas, improves safety for operators, and makes automatic dosing systems more precise.
Why sourcing from Sunrise Chemical Group guarantees stable supply lines amidst volatile global trade conditions.
In the chemical sector, supply chain continuity is vital. Tianjin Sunrise Chem Group mitigates disruption risks through deep backward integration. We manufacture key precursors and intermediates in-house rather than relying entirely on third-party suppliers. This buffer limits price volatility and insulates our customers from localized raw material shortages.
Our strategically positioned manufacturing plant near Tianjin Port (one of the largest deep-water shipping gateways in Northern China) provides clear logistical benefits. It enables prompt inland transfers and offers direct sea routes to textile manufacturing regions in Southeast Asia, South Asia, South America, Europe, and the Middle East. Our on-site warehouses also maintain a constant surplus inventory of basic, direct, and sulphur dyes to fulfill urgent, high-volume orders with minimal delay.
We combine advanced, computer-controlled synthesis plants with real-time laboratory batch verification to ensure that every shipment matches standard color coordinates, fastness, and strength specifications. This reliable workflow minimizes laboratory adjustments for our clients, saving valuable production hours.
Meeting the strict environmental guidelines of modern global supply chains (ZDHC Level 3, GOTS, and ISO standardizations).
Modern global brands require strict chemical compliance. The textile industry continues to move away from restricted arylamines and hazardous heavy metals. To address this, SUNRISE products comply with key international safety certifications:
We work directly with regional technical agencies and testing laboratories to supply buyers with up-to-date Safety Data Sheets (SDS), Technical Data Sheets (TDS), and certification documents. This documentation helps clear custom checks and simplifies compliance verification for local textile finishers.
Professional solutions to common chemical, logistical, and technical concerns when sourcing from China.
Our standard Basic Red 46 (Cationic Red X-GRL) is typically supplied at 250% strength, but we can standardize the strength anywhere from 100% to 250% to match customer specifications. The dye is formulated as a salt-balanced organic monoazo compound with excellent stability and clean water solubility.
We run spectrophotometric assays and comparative test dyeings on every production lot. We evaluate the color value (strength) and color coordinates (L*, a*, b* values) against an established retention standard. No batch is approved for packaging unless it falls within our strict ΔE < 0.5 tolerance limit.
No. Basic Red 46 is cationic (positively charged) and will react with anionic compounds to form insoluble precipitates, resulting in tarring and spotting. Dyers should use only non-ionic or cationic retarders and leveling agents to maintain dispersion stability.
Our standard packaging includes 25kg multi-layer iron drums, fiber drums, or heavy-duty cartons on fumigated pallets, with custom labeling options. We provide complete chemical export documentation, including SDS (GHS compliant), TDS, Certificate of Analysis (COA), and certificate of origin documentation to expedite customs clearance.
