NN dimethyl urea—also known as dimethylurea and 1 1 dimethylurea—is a critical additive in dyestuff assisters, playing a key role in enhancing dye fixation, improving color fastness, and optimizing dyeing efficiency for textiles and industrial materials. Hebei Guangxing Chemical Co., Ltd., established in January 2013 and located in Xinhe County Chemical Industrial Park (covering 90 acres), is a leading manufacturer of nn dimethyl urea with an annual output of 5,000 tons (alongside 6,000 tons/year of 6-amino-1,3-dimethyluracil). The company’s 1 1 dimethylurea meets strict industrial standards, offering high purity (≥99%) and consistent quality—essential for dyestuff applications where even minor impurities can compromise dye performance. For wholesalers supplying dye manufacturers, textile mills, or industrial coating firms, partnering with Hebei Guangxing means accessing scalable dimethylurea solutions that elevate dyestuff assister effectiveness—unlike generic products that fluctuate in purity and fail to deliver reliable results.
Key Functions of NN Dimethyl Urea in Dyestuff Assisters
- Enhances Dye Fixation & Color Fastness with NN Dimethyl Urea : NN dimethyl urea acts as a cross-linking agent in dyestuff assisters, forming strong bonds between dyes and fabric fibers (e.g., cotton, polyester). This significantly improves dye fixation rates (reducing dye loss during washing) and enhances color fastness to water, light, and friction—critical for textiles that need long-lasting color. A dye manufacturer wholesaler reported that 1 1 dimethylurea from Hebei Guangxing increased dye fixation by 30% compared to generic dimethylurea, cutting dye waste and lowering production costs. Wholesalers can emphasize this function to clients, as improved fixation directly boosts dyestuff efficiency and end-product quality.
- Optimizes Dyeing Temperature & Reduces Energy Use with Dimethylurea: Dimethylurea in dyestuff assisters lowers the optimal dyeing temperature by 10–15°C, reducing energy consumption for textile mills. It also improves dye solubility, ensuring uniform color distribution across fabrics (eliminating uneven “splotches”). A textile mill wholesaler noted that using nn dimethyl urea from Hebei Guangxing reduced their clients’ dyeing energy costs by 20% while improving color uniformity—addressing both sustainability goals and quality concerns. Wholesalers can market this as a “win-win feature,” as lower energy use cuts operational costs, and uniform dyeing reduces customer complaints about flawed textiles.

Low moisture (suitable for humid storage); granular form (easy to handle); long shelf life |
Humid-region dye manufacturers, bulk dyestuff assister blending (moisture-sensitive processes) |
≤0.2% moisture (avoids caking); granular structure (reduces dust during handling vs. powder) |
Tips for Wholesalers Promoting NN Dimethyl Urea
- Highlight Purity Consistency & Production Scale: Hebei Guangxing’s nn dimethyl urea is produced in a 90-acre industrial park with annual output of 5,000 tons—ensuring stable bulk supply and consistent purity (≥99%) across every batch. A global dye wholesaler reported that 1 1 dimethylurea from Hebei Guangxing had zero purity fluctuations over 12 months of orders, compared to generic suppliers that had 15% batch-to-batch variation. Wholesalers can use this scale and consistency to attract large dye manufacturers, as stable supply eliminates production delays caused by material shortages or quality issues.
- Emphasize Tailored Solutions for Dyestuff Needs: Hebei Guangxing offers custom dimethylurea solutions—adjustable particle sizes (40–150 mesh), packaging (2–50kg/bag), and even low-moisture formulations for humid regions. A specialty dye wholesaler requested 120-mesh nn dimethyl urea in 5kg bags for small-batch premium dye production—Hebei Guangxing delivered the custom order in 7 days. Wholesalers can frame this customization as a “flexibility advantage,” as it lets clients tailor dimethylurea to their specific dyestuff processes (e.g., fine powder for fast dissolution, granular for dust-free handling).
NN Dimethyl Urea FAQS
Is NN Dimethyl Urea Suitable for Water-Based Dyestuff Assisters?
Yes—Hebei Guangxing’s nn dimethyl urea (especially high-purity and fine-grade variants) is ideal for water-based dyestuff assisters. Its high purity (≥99%) ensures no insoluble impurities disrupt the water-based formulation, and fine particle size (80–150 mesh) dissolves quickly in water—critical for uniform dye dispersion. A water-based dye wholesaler used 1 1 dimethylurea from Hebei Guangxing in their assisters, reporting 95% dissolution within 5 minutes (vs. 60% for generic dimethylurea). Wholesalers can assure clients that nn dimethyl urea is “water-compatible,” with specs tailored to the needs of water-based dye systems.
Can 1 1 Dimethylurea Be Customized for Small-Batch Dye Manufacturers?
Absolutely—Hebei Guangxing offers 1 1 dimethylurea in custom packaging (2–50kg/bag) and particle sizes (40–150 mesh) to fit small-batch dye production. For manufacturers needing small quantities (e.g., 2–10kg per order) for specialty dyes, the company provides flexible minimum order quantities (MOQs) without compromising purity. A boutique textile dye wholesaler requested 5kg bags of 120-mesh 1 1 dimethylurea for silk dyeing—Hebei Guangxing fulfilled the order in 5 days, with the same ≥99.5% purity as bulk orders. Wholesalers can highlight this flexibility to small-batch clients, as generic suppliers often force large MOQs that are impractical for specialty dyeing.
How Does NN Dimethyl Urea Compare to Other Dye Fixatives for Textiles?
NN dimethyl urea outperforms other fixatives (e.g., urea-formaldehyde resins) in three key ways: it’s non-toxic (safe for textile contact), improves color fastness without stiffening fabrics, and works at lower temperatures (reducing energy use). Urea-formaldehyde resins, by contrast, can release harmful fumes and make fabrics rigid. A textile mill wholesaler tested both: dimethylurea from Hebei Guangxing improved color fastness to washing by 2 grades (per AATCC standards) while keeping fabrics soft, compared to resin fixatives that stiffened fabrics and only improved fastness by 1 grade. For dye manufacturers prioritizing safety and fabric quality, nn dimethyl urea is the superior choice—wholesalers can use this comparison to guide clients.
Does Hebei Guangxing Offer Bulk Discounts for NN Dimethyl Urea Orders?
Yes—Hebei Guangxing provides tiered bulk discounts for nn dimethyl urea, dimethylurea, and 1 1 dimethylurea orders. For example, wholesalers ordering 1–5 tons get 5% off, 5–20 tons get 10% off, and 20+ tons get 15% off—plus free shipping for orders over 50 tons. A large dye wholesaler saved 12% on a 30-ton order of nn dimethyl urea for textile clients, making it more cost-competitive than generic suppliers. The company also offers flexible payment terms (e.g., 30% deposit, 70% on delivery) to help wholesalers manage cash flow for bulk purchases. Wholesalers can use these discounts to attract large-scale dye manufacturers, as bulk pricing aligns with their high-volume production needs.
What Quality Controls Ensure Hebei Guangxing’s Dimethylurea Purity?
Hebei Guangxing implements strict quality controls for dimethylurea: every batch undergoes purity testing (via high-performance liquid chromatography, HPLC), moisture analysis (using Karl Fischer titration), and particle size screening (with laser diffraction). The company’s production process is ISO-compliant, with dust-free workshops and automated packaging to prevent contamination. As a result, nn dimethyl urea consistently meets ≥99% purity, with no batch-to-batch variation. A quality-focused dye wholesaler reported that Hebei Guangxing’s 1 1 dimethylurea passed 100% of their in-house purity tests, compared to generic dimethylurea that failed 20% of tests. For wholesalers supplying clients with strict quality requirements (e.g., medical textile dyes), these controls ensure reliable, compliant products.
