GB/T 23343-2009 Textiles - Tests for colour fastness - Colour fastness to domestic and commercial laundering - Oxidative bleach response using a non-phosphate reference detergent incorporating a low temperature bleach activator
Textiles - Tests for colour fastness - Colour fastness to domestic and commercial laundering - Oxidative bleach response using a non-phosphate reference detergent incorporating a low temperature bleach activator
This standard specifies a method for determining the shade change of textiles, of all kinds (excluding silk and wool), to domestic/commercial laundering procedures in which a bleach activator (oxygen bleaching system) is used.
Shade change behavior, resulting from oxygen bleaching, may be observed on the textile after multiple domestic/commercial launderings.
This standard is not applicable for the assessment of the dye staining of adjacent fabrics.
This standard specifies a procedure incorporating the use of ECE non-phosphate reference detergent, sodium perborate tetrahydrate, and the bleach activator tetra-acetylethylenediamine (TAED) (see Appendix A) and another one using the AATCC 1993 zero phosphate reference detergent (without optical brightener), and incorporating sodium perborate monohydrate and the bleach activator sodium nonanoyloxybenzenze sulphonate (SNOBS) (see Appendix B).
This method is applicable to only the detergent and bleaching systems specified in in this standard. Other detergents and bleaching systems may adopt different test conditions and composition contents.
