Foreword

This revised standard adopts ISO 105-C09.2001 "Textiles Tests for color fastness Part C09. resistance to domestic and commercial laundering color fastness Oxidative bleaching reaction of low temperature bleach activator containing phosphate-free detergent standard "and its amendments ISO 105-C09.2001 /Amd. 1.2003.

This standard is based on ISO 105-C09.2001 redrafted with ISO 105-C09.2001 main differences are as follows.

--- Section A. 3 and Chapter B. Chapter 3 increase the use of other means of stirring the contents, delete the mixing time;

--- Modifying paragraphs A. After washing 6 cleaning method of composition of the sample;

--- Increased first A. Chapter 9, "before the assessment, consider the sample on the standard atmospheric conditions cut wet 1h." In the first B. Chapter 10 a Cause, followed sequentially numbered postponed.

The Standard Annexes A and B are normative appendix.

The standard proposed by China Textile Industry Association.

This standard by the National Standardization Technical Committee on Basic Standards Subcommittee Textiles (SAC/TC209/SC1) centralized.

1 Scope

This standard specifies all types of textiles (except wool and silk) through the use of bleaching agents (peroxide bleaching system) family and business After the washing process industry, its color determined by the method.

Textiles after several domestic and commercial laundering procedures, due to the oxidation bleaching action will make it outstanding variation phenomenon.

This standard does not apply to the adjacent fabric staining evaluation.

This standard specifies the use of the standard detergent ECE phosphate-free, sodium perborate tetrahydrate and the bleach activator tetraacetylethylenediamine (TAED) wash Fandi program (see Appendix A), and the use of standard AATCC1993 phosphorus detergent (excluding fluorescent whitening agent), sodium perborate monohydrate and bleaching Active agents nonanoyl benzene sulfonate (SNOBS) washing procedures (see Appendix B).

This method is only for this standard detergent and bleach system. Other detergents and bleach systems may use different test conditions and ingredients.
