The Golden Formula for Raw Material Proportions:
The base color of reflective fabric is determined by the glass microsphere coating, much like a palette requiring precise proportions:
Substrate Selection: The base color deviation of polyester fiber must be controlled within ±5%.
Microsphere Refractive Index: 1.9-2.4 corresponds to different color temperatures.
Adhesive Transmittance: The transparency of water-based resin affects the final color saturation.
Colorant Addition: Inorganic pigments should not exceed 8% of the total weight.
Every action on the production line affects the color direction:
Coating Speed: 18-22 meters per minute achieves uniform film thickness.
Curing Temperature: 120°C Minimal color difference fluctuation within the -140℃ range
Pressure control: Roller pressure deviation exceeding 0.2mm will result in striped color differences.
Ambient humidity: Color stability is ideal under 45-55%RH conditions.
Intelligent adaptation to application scenarios: The same reflective fabric will exhibit different appearances under different environments:
Light source differences: Bluish under sunlight, yellowish under sodium lamps (pre-testing required)
Observation angle: Higher color saturation at a 15° angle.
Lifespan: Natural aging over five years will cause a decrease in brightness of approximately 12%.
Cleaning method: High-pressure water jet washing may accelerate surface fading.
