Gakushin Colorfastness Abrasion Tester
The Gakushin Colorfastness Abrasion Tester is a six-station rubbing test instrument designed to evaluate color transfer, crocking resistance, and abrasion durability of various materials. By simulating repeated rubbing conditions under controlled pressure and movement, the tester helps determine whether materials maintain color stability and surface performance after friction. It is widely used in textile, leather, automotive interior, plastic products, and laboratory quality evaluation applications.
Application
The Gakushin Colorfastness Abrasion Tester is a 6-station rubbing tester used for evaluating crocking, color transfer, and abrasion resistance of leather, fabric, vinyl, stitched seams, plastics, and other materials.
Each station is equipped with:
An adjustable zero-force balanced arm
A removable rub head and retainer, independently weighed
Spring-loaded clamps on the reciprocating table for secure specimen attachment
This allows six unique specimens to be tested simultaneously under controlled conditions. The tester is ideal for automotive, textile, leather, and research laboratories requiring reproducible colorfastness and abrasion testing under dry or wet conditions.

FAQ
(1) What is the Gakushin Colorfastness Abrasion Tester used for?
We use this tester to evaluate whether materials maintain color stability and surface durability after repeated rubbing. It is commonly used for fabrics, leather, automotive interiors, plastics, and coated materials where color transfer and abrasion resistance are important quality indicators.
(2) What materials can be tested with this rubbing tester?
We apply this equipment for textile fabrics, leather products, vinyl materials, automotive interior components, plastic surfaces, and stitched materials. The tester helps compare different materials and finishing processes under controlled dry or wet rubbing conditions.
(3) What is the difference between dry and wet rubbing tests?
We perform dry rubbing tests to evaluate normal friction-related color transfer, while wet rubbing tests simulate conditions where moisture affects material performance. The selection depends on the product application and the requirements of the applicable testing standard.
(4) Which industries commonly use a Gakushin Colorfastness Abrasion Tester?
We supply this type of tester mainly for textile manufacturers, automotive interior suppliers, leather product companies, material research centers, and third-party laboratories. These industries use test results for quality control, material selection, and product verification.
(5) How should customers select a suitable colorfastness abrasion tester?
We recommend that customers confirm the required testing standards, material type, rubbing load, test method, and number of stations needed for laboratory efficiency. Our QINSUN engineers can provide professional technical guidance and detailed parameters to help customers select suitable testing equipment.
