4-station Leather Rubbing Color Fastness Tester

Tillämpliga standarder

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.

Arbetsprincip

The tester operates via controlled mechanical abrasion:

Sample Mounting: Leather or fabric specimens are clamped into 4 individual stations.

Friction Head Application: A weighted abrading cloth (9 N load) moves back and forth across the sample surface.

Cycle Execution: The machine completes 50–100 cycles (customizable) to simulate wear.

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.

Automotive: Testing seat covers, steering wheels, and interior trims.

Apparel: 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.
