21、 the colour of textiles com- posed 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 reference in this text, constitute p

25、abric: 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 adja- cent fabric(s) are assessed with the grey scales. 4 Apparatus
26、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, 1 911, brought to pH 3,5 with acetic acid immediately before the test. The exact concentrati
27、on of the sodium chlorite sol- ution employed is determined by titration with sodium thiosulfate solution. 4.3 Adjacent fabrics (see IS0 105-AO1 :1989, cub- clause 8.3). Either: 4.3.1 A multifibre adjacent fabric, complying with IS0 105-F1 O. Or: 4.3.2 Two single-fibre adjacent fabrics, complying wi
28、th the relevant sections of Fol to F08 of IS0 105-F:1985, to be assessed for staining. Page 4 EN IS0 105-NO3 : 1995 4.4 If required, a non-dyeable fabric (for example, polypropylene). 4.5 Grey scale for assessing change in colour, complying with IS0 105-A02, and grey scale for as- sessing staining,
29、complying with IS0 105A03. 5 Test specimen 5.1 If the textile to be tested is fabric, a) 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 fa
30、ce of the specimen; or b) attach a specimen measuring 40 mm x 100 mm between the two single-fibre adjacent fabrics (4.321, atso 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 equa
31、l to onehalf af the combined mass of the adjacent fabrics and a) place it between a 40 mm x 100 mm piece of the multifibre adjacent fabric and a 40 mm x 100 mm piece of the non-dyeable 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
32、100 mm piece of each of the two specified single-fibre fabrics and sew along all four sides. 6 Procedure I 6.1 Wet out the composite specimen in the sodium chlorite solution (4.21 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
33、. 6.2 Rinse the composite specimen for 10 min in cold, running tap-water. Open out the 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 s
34、titching. 6.3 Assess the change in colour of the specimen and the staining of the adjacent fabric(s1 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 IS0 105, .e. IS0 105-N03:1993; b) all details
35、necessary for the identification of the sample tested; c) the numerical rating for the change in colour of the specimen; d) if single-fibre adjacent fabrics were used, the nu- merical rating for staining of each kind of adjacent fabric used; e) if a multifibre adjacent fabric was used, the type of m
36、ultifibre adjacent fabric used and the staining of each type of fibre in the multifibre adjacent fabric. _ CEN EN*ISO*LO5- NO3 95 3404589 0096332 T79 W Page U EN IS0 105-NO3 : 1995 Annex ZA (normative) Normative references to international publications with their relevant European publications This
