4-station Leather Rubbing Color Fastness Tester

Criterios aplicables

The tester adheres to global colorfastness and material testing protocols, including:

• ISO 11640 (Leather – Color fastness to rubbing)
• SATRA TM170 (Standard method for color fastness to rubbing)
• AATCC 8 (Colorfastness to Crocking: AATCC Crockmeter Method)
• ISO 105-X12 (Textiles – Color fastness to rubbing)
• GB/T 3920 (China’s national standard for color fastness to rubbing)

These standards ensure consistent evaluation of color transfer, dye adhesion, and surface durability.

Parámetros principales

Principio de funcionamiento

The tester operates via controlled mechanical abrasion:

1. Sample Mounting: Leather or fabric specimens are clamped into 4 individual stations.
2. Friction Head Application: A weighted abrading cloth (9 N load) moves back and forth across the sample surface.
3. Cycle Execution: The machine completes 50–100 cycles (customizable) to simulate wear.
4. Color Assessment: Post-test, the abrading cloth is evaluated for dye transfer using a gray scale (AATCC EP1, ISO 105-A03) or spectrophotometer.

Test Principle & Applications

• Color Fastness Evaluation (ISO 11640/AATCC 8):
  • The abrading cloth is rated on a 1–5 gray scale (1 = severe staining, 5 = no transfer).
  • Pass/fail criteria depend on industry standards (e.g., ≥4 for automotive upholstery).
• Key Industries:
  • Leather Goods: Validating color retention in handbags, shoes, and furniture.
  • Automóviles: Testing seat covers, steering wheels, and interior trims.
  • Ropa: Assessing dye stability in jackets, gloves, and accessories.

The 4-Station Leather Friction Color Fastness Tester streamlines quality control, enabling manufacturers to optimize formulations, reduce rejections, and meet regulatory compliance efficiently. Its multi-sample capability and adherence to global standards make it a cornerstone of material testing laboratories.
