NATIONAL FOREWORD

This Indian Standard (Part D01) which is identical with ISO 105-D01 : 2010 ‘Textiles - Tests for colour fastness - Part D01: Colour fastness to drycleaning using perchloroethylene solvent’ issued by the International Organization for Standardization (ISO)was adopted by the Bureau of Indian Standards on recommendation of the Chemical Methods of Test Sectional Committee and approval of the Textile Division Council.

Colour fastness of dyed/printed textile materials to various agencies during their further treatment or actual use, is an important performance requirement from the users or consumers point of view. The various agencies, to which textile materials may be subsequently subjected may include water, acids, alkalis, organic solvents, washing, laundering, dry-cleaning, perspiration, light, gaseous fumes, bleaching, rubbing, carbonizing, felting, degumming etc. and the colour of textile materials should be fast to these agencies and should not change considerably. The colour should also not bleed and stain the adjacent fabrics which are subjected to these agencies along with coloured fabrics. The colour fastness property of coloured textiles is, therefore, measured in terms of colour fastness, ratings with respect to change in colour and/or staining of adjacent fabrics.
