Rotary Crockmeter YG(B)571XZ

[Instrument Name]: Rotary Crockmeter, Rubbing Color Fastness Tester

[Scope of Application]:

It is used to evaluate the degree of color transfer from the surface of colored textiles to other surfaces due to friction. It is applicable to various types of colored yarns and fabrics made from different fibers, including those that are dyed, printed, or colored via other methods. It is particularly suitable for printed textiles with surface areas too small for testing with standard crockmeters.
