StandardDetails

1.1 This part of ISO 105 specifies a method for de- termining the resistance of the colour of textiles of all kinds and in all forms to dry cleaning. 1.2 This method is not suitable for the evaluation of the durability of textile finishes, nor is it intended for use in evaluating the resistance of colours to spot and stain removal procedures used by the dry-cleaner. 1.3 This test covers colour fastness to dry cleaning only; commercial dry-cleaning practice normally in- volves other operations such as water spotting, sol- vent spotting, steam pressing, etc., for which other Standard test methods are available if the full “dry cleanability” of the textile is to be assessed. 1.4 The presence of absorbed water in either the fabric or the dry-cleaning Solution, or the presence of a detergent and water in the dry-cleaning Solution, has not been found to be a critical factor in assessing colour fastness. This test gives results which correlate satisfactorily with those obtained in commercial dry cleaning. 1.5 Fastness to dry cleaning, without further quali- fication, means fastness to dry cleaning in per- chloroethylene. However, if required, other solvents may be used.
