For assessing change in colour and staining, complying with FZ/T 01023 and FZ/T 01024.5 Test Specimena) Attach a specimen 100 mm × 40 mm to a piece 100mm×40mm of the multifibre adjacent fabric (5.5.1). Sew along one of the shorter edges, with the multifibre adjacent fabric next to the face side of the specimen;6 Operating ProcedureAdopting the same procedure, wet a composite specimen in the acid solution at pH 5.5 (±0.2) (4.4). Then test it in a separate pre-heated test device. Note. Up to 10 test specimens, each separated from the next by one plate, can be tested in one test device simultaneously. If less than 10 specimens are prepared, all 11 plates must still be used to maintain the correct nominal pressure. Open out each composite specimen (by breaking the stitching except on one of the shorter sides, if necessary). Dry it by hanging it in air at a temperature not In many cases of cellulosic fibres dyed with direct dyes containing copper, or after treatment with copper salts, the prescribed tests and natural perspiration bring about a removal of copper from the dyeings.7 Test ReportThe test report shall include the following information. a) serial number of this Standard; b) all details of the sample tested; ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
