Dry Wet rubbing fastness Tester

Brief Introduction:

AATCC Manual Crockmeter is designed with a base, rubbing rotation mechanism and a counter. Fix the specimen and sand paper with the specimen clamp on one side of the base.

Rotate the knob to rub the friction head with the white cotton cloth against the specimen in reciprocation motion with specified strokes. After ten times of friction between the white cloth and the specimen, assess the color transfer to the white cloth with a gray scale and the stability of dyed fabric specimen or surface coating so as to provide reference data for material assessing and selection.
