Gakushin Tester

This Gakushin Type Rubbing Tester is a standard testing machine of the Type II rubbing tester (GAKUSIN TYPE) specified in JIS L0849 Test Method of Rubbing Fastness in JIS Textile-Tests For Color Fastness. It is applied to determine the color resistance of dyed or printed textiles to rubbing thus providing evidence for textile products R&D and acceptance inspection.

It is reported that this tester is stricter than the ordinary horizontal reciprocation rubbing color fastness tester whose evaluating results are worse with the same specimen tests.
