The UK participation in its preparation was entrusted by Technical Committee TCI/25, Chemical properties, to Subcommittee TCI/25/-/10, Colour fastness, which has the responsibility to: aid enquirers to unde
4、rstand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on

20、rdization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right t
21、o be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft Internation
22、al Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75%of the member bodies casting a vote. International Standard ISO105-X08was prepared by Technical Committee ISO/TC38, Textiles, Subc
23、ommittee SC1, Tests for coloured textiles and colorants. This fourth edition cancels and replaces the third edition (ISO105-X08:1987), of which it constitutes a technical revision. ISO105was previously published in thirteen “parts”, each designated by a letter (e.g. “Part A”), with publication dates
24、 between1978and1985. Each part contained a series of “sections”, each designated by the respective part letter and by a two-digit serial number (e.g. “Section A01”). These sections are now being republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric
25、 designations. A complete list of these parts is given in ISO105-A01. Descriptors: Textiles, dyes, tests, determination, colour fastness, soaps.iv blankENISO105-X08:1997 BSI 09-1999 1 1 Scope This part of ISO105specifies a method for determining the resistance of the colour of textiles of all kinds,
26、 except loose fibre, to the action of soap solutions such as those used in degumming raw silk. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of ISO105. At the time of publication, the editions indicated were valid. All
27、standards are subject to revision, and parties to agreements based on ISO105 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

29、es Tests for colour fastness Part F: Standard adjacent fabrics. 3 Principle A specimen of the textile in contact with adjacent fabrics is treated with a soap solution, then rinsed and dried. The change in colour of the specimen and the staining of the adjacent fabrics are assessed by comparison with
30、 the grey scales. 4 Apparatus and reagents 4.1 Vessel, of capacity500ml, with appropriate reflux condenser. 4.2 Soap, containing not more than5%moisture and complying with the following requirements based on dry mass: free alkali, calculated as Na 2 CO 3 : 0,3g/kg maximum; free alkali, calculated as
31、 NaOH: 1g/kg maximum; total fatty matter: 850g/kg minimum; titre of mixed fatty acids prepared from soap:30 C maximum; iodine value: 50maximum. The soap shall be free from fluorescent brightening agents. 4.3 Soap solution, containing7g of soap (4.2) per litre of grade3water (4.5). 4.4 Sodium carbona
32、te, anhydrous (Na 2 CO 3 ). 4.5 Grade 3water, (see ISO105-A01:1994, subclause 8.1). 4.6 Two single-fibre adjacent fabrics, one piece made of raw silk, complying with section F06of ISO105-F:1985, the other made of the same kind of fabric as that of the textile to be tested or that pre-dominating in t
33、he case of blends, complying with the relevant section of F01to F08of ISO105-F:1985. 4.7 Grey scale for assessing change in colour, complying with ISO105-A02, and grey scale for assessing staining, complying with ISO105-A03. 5 Test specimen 5.1 If the textile to be tested is fabric, attach a specime
34、n measuring40mm 100mm between the two single-fibre adjacent fabrics (4.6), also measuring40mm 100mm, by sewing along one of the shorter sides. 5.2 If the textile to be tested is yarn, knit it into fabric and treat it as in5.1 or form a layer of parallel lengths of it between the two adjacent fabrics
35、 (4.6), the amount of yarn taken being approximately equal to half the combined mass of the adjacent fabrics. Sew along all four sides to hold the yarn in place and to form a composite specimen. 6 Procedure 6.1 Treat the composite specimen in the vessel (4.1) for10min under reflux with a lightly boi
36、ling soap solution (4.3) at a liquor ratio of 100 : 1. 6.2 After10min, add0,5g of anhydrous sodium carbonate (4.4) per litre of the boiling soap solution and keep boiling lightly for another110min (2h in all). 6.3 Remove the composite specimen from the soap solution, rinse twice in cold grade3water
37、(4.5) and then for10min in cold, running tap-water. Squeeze the composite specimen thoroughly, open it out (by breaking the stitching on all sides except one of the shorter sides, if necessary) and dry it by hanging it in air at a temperature not exceeding60 C, with the three parts in contact only a
38、t the remaining line of stitching. 6.4 Assess the change in colour of the specimen and the staining of the adjacent fabrics by comparison with the grey scales (4.7). 7 Test report The test report shall include the following information: a) the number and year of publication of this part of ISO105, i
39、.e. ISO105-X08:1994;ENISO105-X08:1997 2 BSI 09-1999 b) all details necessary for the identification of the sample tested; c) the numerical grey scale rating for the change in colour of the specimen; d) the numerical grey scale rating for staining of each kind of adjacent fabric used.ENISO105-X08:199
