METER – DIGITAL MODEL is used to determine the Color Fastness against rubbing
Pre-set Counter with LCD Display.One of the test for determination of colour fastness
of dyed or printed textiles or leather is the crocking test. This crock meter suppliers is used for the determination of
colour fastness against rubbing, either under dry or under wet conditions. In this test and moving brass finger of
specified shape and size rubs against the test specimens under test and the
amount of colour transferred to a piece of abradant fabric fixed over the base
of the moving finger are graded with the help of standard grey scales to
evaluate the colour fastness against rubbing.
‘VGOTECH’ Crock Meter Suppliers consists of a rigid flat metalic platform on which the test specimen
can be held firmly and a abrading finger which rubs against it under a
specified load.The platform is fixed
over the base of the equipment and lies in a horizontal plane.The test specimen is held firmly over an
abrasive paper which is pasted on the upper face of the platform, with the help
of two pins holding it at both ends.
abrading finger has a flat circular rubbing face which is covered with 4 piece
of white abradant fabric during the test.
The abradant fabrics picks up colour lost by the test specimen during
rubbing. It is held over the finger with
the help of a tapered ring. Motion to
the finger is given through a reciprocating arm with runs an two ball bearings
to minimize friction and to apply a uniform load on the finger. The arm is
moved by a manually operated crank and connecting link.
The Crock Meter equipment is finished in dark metallic paint
and bright chrome plating to give it a corrosion resistant finish.
