Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Textile Grade Iron Oxide Pigments
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Modernizing Textile Coloration
Deqing Demi Pigment Technology Co., Ltd. is at the forefront of the "Dry-Dyeing" revolution. We recognize that the textile industry is moving away from water-intensive dyeing processes. Our textile-grade series is designed for "Mass Coloration"—adding color directly to the polymer melt. We provide the permanent, light-stable color foundation that allows textile manufacturers to create high-performance fabrics that are as kind to the environment as they are durable.
Textile Grade Usage Areas
- Outdoor Fabrics: UV-permanent coloring for awnings, umbrellas, and tents.
- Military Uniforms: Low-IR signature pigments for camouflaged gear.
- Automotive Carpets: High-heat stable colorants for car interiors and mats.
- Non-Woven Fabrics: Durable coloring for medical and industrial textiles.
Textile Grade Technical Specs
| Metric | Value | Standard |
| Particle Size (D99) | < 2.0 μm | Laser Diffraction |
| Filter Pressure Value | < 1.0 bar/g | EN 13900-5 |
| Heat Stability | Up to 300∘C | Internal Method |
| Wash Fastness | Grade 5 (Excellent) | ISO 105-C06 |
| Moisture Content | Max 0.2% | ISO 787-2 |
Performance Characteristics
- Permanent Fusion: The color is locked inside the fiber, not just on the surface.
- UV-Shielding: Protects the polymer fiber from sunlight degradation.
- Chemical Resistance: Unaffected by dry cleaning, bleaching, or harsh detergents.
- Water-Saving: Eliminates the need for traditional liquid dyeing baths.
Q: Can these be used for "Melt-Spinning" Polyester?
A: Yes, our pigments are heat-stable enough for PET spinning and fine enough to pass through standard mesh filters.
Q: Is the color safe for skin contact?
A: Absolutely. Our mineral pigments are inorganic and certified to meet Oeko-Tex Standard 100 requirements.
Fiber Technical Support
We offer "Filterability Testing," providing the exact bar-pressure data for our pigments in your specific resin (PP, PA, or PET) to ensure long production runs.
Custom Masterbatch Pellets: We can provide our textile pigments pre-formulated into fiber-grade masterbatches for immediate use in your spinning lines.
The Science of Solution Dyeing
In textile science, we focus on "Particle Interference." If a pigment particle is too large, it creates a weak point in the fiber, leading to "Breakage." We employ "Wet Milling" technology to ensure that 100% of our particles are significantly smaller than the fiber diameter. This allows the pigment to act as a reinforcing filler rather than a defect. We also optimize the "Aspect Ratio" of the particles to ensure that light is reflected uniformly, providing a consistent luster and color depth across miles of yarn.
