Test Principle

The Rubbing Color Fastness Tester evaluates material rubbing performance by simulating actual friction conditions using a specified load, defined rubbing head shape, and standardized reciprocating distance.

The rubbing head repeatedly rubs the test material to assess color transfer, rubbing marks, and wear degree caused by friction, thereby determining the rubbing color fastness of the material.

Operating Instructions

Sample Preparation:

Select an appropriate rubbing head and load weight according to the material type.

Equipment Setup:

Set the curvature radius of the test table and the load value in accordance with the test standard to ensure accurate test conditions.

Start Test:

Press the start button; the rubbing head automatically performs the specified reciprocating motion and records test data.

Test Completion:

After the test, evaluate the sample according to color difference assessment standards and perform data analysis.

Safety Precautions:

Ensure the safety cover is properly installed during operation to prevent accidental contact with moving components.
