26、fabrics is treated in a sodium chlorite solution, rinsed and dried. The change in colour of the specimen and the staining of the adja- cent fabric(s) are assessed with the grey scales. 4 Apparatus and reagents 4.1 Glass container, fitted with a reflux condenser or other means of reducing evaporation
27、 of the bath, thus preventing the need to modify the bath during the test. 4.2 Sodium chlorite solution, 2,5 gil, containing 0,l g of acid sodium pyrophosphate per litre. brought to pH 3,5 with formic acid immediately before the test. The exact concentration of the sodium chlorite em- ployed is dete
28、rmined by titration with sodium thiosulfate solution. 4.3 Adjacent fabrics (see IS0 105-A01:1989, sub- clause 8.3). Either: 4.3.1 A multifibre adjacent fabric, complying with IS0 105-FIO. Or: 4.3.2 Two single-fibre adjacent fabrics, complying with the relevant sections of Fol to F08 of IS0 105-F:198
29、5, 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, compiying with IS0 105-A02, and grey scale for as- sessing staining, complying with IS0 105A03. 5 Test specimen 5.1 If the textile to be tested is fabric
30、, a) or b) attach a specimen measuring 40 mm x 100 mm to a piece of the multifibre adjacent fabric (4.3.11, also measuring 40 mm x 100 mm, by sewing along one of the shorter sides, with the multifibre fabric next to the face of the specimen; attach a specimen measuring 40 mm x 100 mm between the two
31、 single-fibre adjacent fabrics (4.32, also measuring 40 mm x 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 of the combined mass of the adjacent fabrics and a) place it between a
32、40 mm x 100 mm piece of the multifibre adjacent fabric and a 40 mm x 100 mm piece of the nondyeable fabric (4.4) and sew them along all four sides (see IS0 A01:1989, subclause 9.6); or b) place it between a 40 mm x 100 mm piece of each of the two specified single-fibre fabrics and sew along all four
33、 sides. 6 Procedure 6.1 Wet out the composite specimen in the sodium chlorite solution (4.2) and immerse it in the solution for 1 h without agitation, at a temperature of 80 “C f 2 “C and at a liquor ratio of 50:l. 6.2 Rinse the composite specimen for 10 min in cold, running tap-water. Open out the
34、composite 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 exceeding 60 “C with the parts in contact only at the remaining line of stitching. 6.3 Assess the change in colour of the specimen and the staining of the adjac
35、ent fabrick) with the grey scales (4.5). 7 Test report The test report shall include the following particulars: the number and date of publication of this part of IS0 105, .e. IS0 105-N04:1993; all details necessary for the identification of the sample tested; the numerical rating for the change in
36、colour of the specimen; if single-fibre adjacent fabrics were used, the nu- merical rating for staining of each kind of adjacent fabric used; if a multifibre adjacent fabric was used, the type of multifibre adjacent fabric used and the staining of each type of fibre in the multifibre adjacent fabric
