Leather Rubbing Colorfastness Tester

Abrasion & Color Transfer Testing
A reciprocating arm (10–200 mm/s) rubs leather samples against abrasive pads (cork, sandpaper) while UV-Vis spectrometers quantify dye transfer (ΔE <0.5 ISO 105-J02). A humidity chamber (RH 65% ±5%) simulates sweat-induced fading.

Key Parameters

• Rubbing Cycles: Up to 10,000 cycles with load cells (5–20 N).
• Color Fastness: Graded 1–5 (ISO 105-X12) for handbags and upholstery.

Applications

• Apparel: Tests workwear for color retention during industrial use.
• Automotive: Validates leather seat covers for UV/sweat resistance.
• Luxury Goods: Ensures consistency in exotic skin products.

Industry Impact
Reduces returns by 22% for tanneries using pre-test quality scoring.

Innovation
Robotic arms replicate human motion patterns (e.g., sitting friction), outperforming ASTM D5267 methods.
