IS/ISO 105 : Part C10 : 2006 Textiles - Tests for Colour Fastness - Part C10 : Colour Fastness to Washing with Soap or Soap and Soda

NATIONAL FOREWORD

This Indian Standard (Part C10) which is identical with ISO 105-C10 : 2006 'Textiles - Tests for colour fastness - Part C10: Colour fastness to washing with soap or soap and soda' issued by the Internat ional Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Chemical Methods of TestSectional 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 viewpoint of the user or consumer. The various agenc ies 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 agE!ncies 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.

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 Standards.The Indian Standards are being published in Sections A to Z.
