26、le A specimen of the textile in contact with one or two specified adjacent fabrics is immersed in the bleaching solution, rinsed and dried. The change in colour of the specimen and the staining of the adjacent fabric(s) are assessed with the grey scales. 4 Apparatus and reagents 4.1 Test tube, of di
27、ameter and length such that the composite specimen roll will have a reasonably snug fit in the tube and be covered by the bleaching solution (4.3). 4.2 Reflux condenser, fitting the test tube (4.1), to reduce evaporation from the bleaching bath during the test. 4.3 Bleaching bath, of the composition
28、 given in Table 1. Prepare the bleaching bath as follows: Place cold grade 3 water (4.7) in the bath. Add sodium silicate (or sodium pyrophosphate for bath 3). Add magnesium chloride. Adjust the pH. Add hydrogen peroxide. Heat to the appropriate temperature specified in Table 1. 4.4 Adjacent fabrics
29、, each measuring 40 mm 100 mm (see ISO 105-A01:1989, subclause 8.3). Either: 4.4.1 A multifibre adjacent fabric complying with ISO 105-F10. Or: 4.4.2 Two single-fibre adjacent fabrics, complying with the relevant sections of F01 to F08 of ISO 105-F:1985, one piece being made of the same kind of fibr
30、e as that of the textile to be tested, or that predominating in the case of blends, and the second piece being made of the fibre as indicated in Table 2, or, in the case of blends, of the kind of fibre second in order or predominance, or as otherwise specified. 4.5 If required, a non-dyeable fabric
31、(for example polypropylene). 4.6 Grey scale for assessing change in colour, complying with ISO 105-A02, and grey scale for assessing staining, complying with ISO 105-A03. 4.7 Grade 3 water (see ISO 105-A01:1989, clause 8.2).

33、pecimen; or b) attach a specimen measuring 40 mm 100 mm between the two single-fibre adjacent fabrics (4.4.2), also measuring 40 mm 100 mm, by sewing along one of the shorter sides. 5.2 Where yarn or loose fibre is to be tested, take a mass of the yarn or loose fibre approximately equal to one-half
34、of the combined mass of the adjacent fabrics and a) place it between a 40 mm 100 mm piece of the multifibre adjacent fabric and a 40 mm 100 mm piece of the non-dyeable fabric (4.5) and sew them along all four sides (see ISO 105-A01:1989, subclause 9.6); or b) place it between a 40 mm 100 mm piece of
35、 each of the two specified single-fibre fabrics and sew along all four sides. 6 Procedure 6.1 Loosely roll the composite specimen in the direction of the long edge, place the 40 mm roll into the test tube containing the appropriate bleaching solution (see Table 1) and keep it well covered by the ble
