IS 4802 : 1988 Method for determination of colour fastness of textile materials to dry-cleaning

1 Scope

1.1 This standard prescribes a method for determination of colour fastness oftextile materials of all kinds and in all forms to dry-cleaning.

1.2 The test prescribed in this standard is not suitable for evaluation ofthe durability of textile finishes, nor it is intended for use in evaluating theresistance of colours to spot and stains removal procedures used by thedry-cleaners (see Notes 1 and 2).

Note 1 - This test covers colours fastness to dry-cleaning only; commercialdry-cleaning practice normally involves other operations, such as waterspotting, solvent spotting, steam pressing, etc, for which other standard testmethods are available, if the full `dry- cleanability of the textile is to beassessed.

Note 2 - The presence of absorbed water in either the fabric or dry-cleaningsolution, or the presence of a detergent water in the dry-cleaning solution, hasnot been found to be a critical factor in assessing colour fastness, This testgives results which correlate satisfactorily with those obtained in commercialdry-cleaning.
