22、od for determining the resistance of the colour of textiles composed of natural and regenerated cellulose, and synthetic fibres, to the action of mild bleaching with sodium chlorite as employed in textile processing. 2 Normative references The following standards contain provisions which, through re
23、ference in this text, constitute provisions of this part of ISO105. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO105 are encouraged to investigate the possibility of applying the most recent e
24、ditions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

26、t fabric: Multifibre. 3 Principle A specimen of the textile in contact with one or two specified adjacent fabrics is treated in a sodium chlorite 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
27、 and reagents 4.1 Glass container, fitted with a reflux condenser or other means of reducing evaporation of the bath, thus preventing the need to modify the bath during the test. 4.2 Sodium chlorite solution,1g/l, brought to pH3,5 with acetic acid immediately before the test. The exact concentration
28、 of the sodium chlorite solution employed is determined by titration with sodium thiosulfate solution. 4.3 Adjacent fabrics (see ISO105-A01:1989, subclause8.3). Either: 4.3.1 A multifibre adjacent fabric, complying with ISO105-F10. Or: 4.3.2 Two single-fibre adjacent fabrics, complying with the rele
29、vant sections of F01 to F08 of ISO105-F:1985, to be assessed for staining. 4.4 If required, a non-dyeable fabric (for example, polypropylene). 4.5 Grey scale for assessing change in colour, complying with ISO105-A02, and grey scale for assessing staining, complying with ISO105-A03. 5 Test specimen 5
30、.1 If the textile to be tested is fabric, a) attach a specimen measuring40mm 100mm to a piece of the multifibre adjacent fabric(4.3.1), also measuring40mm 100mm, by sewing along one of the shorter sides, with the multifibre fabric next to the face of the specimen; or b) attach a specimen measuring40
31、mm 100mm between the two single-fibre adjacent fabrics(4.3.2), also measuring40mm 100mm, 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 of the combined mass of the adjacent fabrics and a)
32、 place it between a40mm 100mm piece of the multifibre adjacent fabric and a40mm 100mm piece of the non-dyeable fabric(4.4) and sew them along all four sides (seeISOA01:1989, subclause9.6); or b) place it between a40mm 100mm piece of each of the two specified single-fibre fabrics and sew along all fo
33、ur sides. 6 Procedure 6.1 Wet out the composite specimen in the sodium chlorite solution(4.2) and immerse it in the solution for1h without agitation, at a temperature of80 C 2 C and at a liquor ratio of50:1. 6.2 Rinse the composite specimen for10min in cold, running tap-water. Open out the composite
34、 specimen by breaking the stitching on all sides except one of the shorter sides and dry by hanging it in air at a temperature not exceeding60 C with the parts in contact only at the remaining line of stitching.EN ISO 105-N03:1995 4 BSI 10-1999 6.3 Assess the change in colour of the specimen and the
35、 staining of the adjacent fabric(s) with the grey scales(4.5). 7 Test report The test report shall include the following particulars: a) the number and date of publication of this part of ISO105, i.e.ISO105-N03:1993; b) all details necessary for the identification of the sample tested; c) the numeri
36、cal rating for the change in colour of the specimen; d) if single-fibre adjacent fabrics were used, the numerical rating for staining of each kind of adjacent fabric used; e) if a multifibre adjacent fabric was used, the type of multifibre adjacent fabric used and the staining of each type of fibre
37、in the multifibre adjacent fabric.EN ISO 105-N03:1995 BSI 10-1999 5 Annex ZA (normative) Normative references to international publications with their relevant European publications This European Standard incorporates, by dated or undated reference, provisions from other publications.
