4-station Leather Rubbing Color Fastness Tester

Application

1. Leather Product Quality Control

This involves colorfastness testing for leather uppers, linings, garments, bags, and other products.

It ensures that leather products maintain a good appearance and performance during long-term use, meeting consumer demands.

2. New Product Development

This involves evaluating the rub fastness performance of new leather materials to provide a basis for product improvement.

It optimizes leather dyeing processes and enhances the market competitiveness of products.

3. Third-Party Testing Institutions

This provides independent colorfastness testing services for leather product manufacturers.

It ensures that products meet relevant standards or customer requirements, increasing customer trust.

Standards

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.

Feature

1. Dry and Wet Friction Test Supports dry or wet wool felt as the friction medium, simulating friction conditions under different environments.

2. Multi-Station Parallel Testing The four-station design allows for simultaneous testing of four samples, improving testing efficiency.

3. Damage and Discoloration Assessment The friction color fastness grade of the leather is evaluated based on the degree of staining on the wool felt after friction and the discoloration of the leather itself.
