Test specifications
Test number : AATCC Test Method 8-2005,ISO 105-X12,
This test specifies a method for determining the resistance of the colour of textiles of all kinds, including textile floor coverings and other pile fabrics, to rubbing off and staining other materials.
Crockmeter
is used for testing the transference of color from the surface of one material
to another by either wet or dry rubbing.
Specifications
of apparatus as per standard :- ISO 105, BS 1006, AATCC 8, BS EN 20105
Testing
of color fastness to Dry Rubbing
Properly mount the specimen and test cloths. Reset
the counter . The finger is positioned
on the specimen at the base’s front end and handle is rotated in the clockwise
direction at the rate of approximately 1 revolution per second. The handle is
then rotated equal to the number of strokes specified by the test method.When
the desired number of strokes is reached, the crocking cloth is removed from
the finger and its degree of staining has to be evaluated by SDC grey scale.
Testing
of color fastness to Wet Rubbing:
A fresh piece of crocking cloth is soaked in distilled
water and the excess water is removed so that it contains its own mass of
water.This wet piece of the crocking cloth is fixed over the end of the finger
of the Crockmeter and the test is undertaken.
The dyed or printed fabric is mounted on the lower platform.Then 10 cycles are rubbed with a white fabric. The extent of color that rubs away onto the white fabric is determined against the grey scale for staining. click here for detail:- Standard Test method
