The electronic crockmeter applies to textiles, knitted fabrics, leather, power of metal plates, printing and other industries. Evaluation of friction test for color fastness. Therefore available to the routine testing of production and scientific research units and the development of standards. This instrument uses advanced technology, with automatic control circuit, and is more advanced at home and abroad friction color fastness instrument. And versatile, reciprocating frequency can be set.

Application:

Used to determine the colour fastness of cotton, chemical fiber, blended, other coloured fabrics and leather to dry or wet rubbing. Motorised for frequent use and long run tests.

A piece of dyed test cloth and a piece of white cotton cloth are rubbed against each other though the tester in a specific pressure and stroke.
The color fastness of the sample is graded by comparing the coloring of the white cotton with the gray scale. Fitted with digital electronic presettable counter for strokes.

Standards:

1. GB/T3920-97 "color fastness of textiles abrasion test method, "

2. GB/T5712-97 "organic solvent-resistant textile friction color fastness test method"

3. GB/T420-90 "printing and dyeing cloth scrub fastness test method "
