IS/ISO 105 : PART C07 : 1999 : Textiles - Tests for colour fasteness : Part C07 Colour fasteness to wet scrubbing of pigment textiles

Note : (Superseding IS 11908 : 1986)

NATIONAL FOREWORD

This Indian Standard (part CO?) which is identical with ISO 105-CO? : 1999 'Textiles - Tests for colour fastness - Part CO?: Colour fastness to wet scrubbing of pigment printed textiles' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Chemical Methods of Test Sectional Committee and approval of the Textile Division Council.

This standard supersedes IS 11908 : 1986 'Method for determination of colour fastness of textile fabrics to wet scrubbing'.

Colour fastness of dyedlprinted textile materials to various agencies during their further treatment or actual use is an important performance requirement from the viewpoint of the user or consumer. The various agencies to which textile materials may be subsequently subjected may include water, acids, alkalis, organic solvents, washing, laundering, drycleaning, perspiration, light, gaseous fumes, bleaching, rubbing, carbonizing, felting, 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 andlor staining of adjacent fabrics.

Since colour fastness is one of the most important requirement for export of textiles, it is considered essential that Indian Standards related to colour fastness are completely harmonized with International Standards. The various Indian Standards on colour fastness testing, are, therefore , being revised to align them with the corresponding International Standardsand are being published in Parts A to Z.

This standard is intended to test colour fastness of textile materials to domestic or commercial laundering procedures used for normal household articles. Industrial and hospital articles may be subjected to social laundering procedures which may be severe in some respects.
