21、tion of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committ
22、ee. International organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Drafi International Standards adopted by the tec
23、hnical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 105-206 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for
24、cooured textiles and colorants. IS0 105 was previously published in thirteen “parts”, each designated by a letter (e.g. “Part A), with publication dates between 1978 and 1985. Each part contained a series of “sections”, each designated by the respective part letter and by a two-digit serial number (
25、e.g. Section A01)”). These sections are now being republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric designations. A complete list of these parts is given in IS0 105-A01. Annex A of this part of IS0 105 is for information only. STD.BSI BS EN IS0

27、tly referred to as colorants, and which may also contain different types and amounts of migration inhibitors. The degree of migration is obtained by visual examination or by reflectance measurements. The test method may be used to compare the migration propensity of dyes and the effect on migration
28、of different types of migration inhibitors, thickeners and electrolyte. The method may also be used to evaluate a pad liquor with which migration has been found on a continuous dye range. 2 Normative reference The following standard contains provisions which, through reference in this text, constitu
29、tes provisions of this part of IS0 105. At the time of publication, the edition indicated was valid. All standards are subject to revision and parties to agreements based on this part of IS0 105 are encouraged to investigate the possibility of applying the most recent edition of the standard listed

IS0 105-A02: 1993, Textiles - Tests for colour fastness - Part A02 Grey scale for assessing change in colour. 3 Definitions For the purposes of this part of IS0 105, the following definitions apply. 3.1 degr
31、ee of permanence. dye: Colorant applied to or formed on a substrate, via the molecularly dispersed state, which exhibits some 3.2 migration: Movement of a chemical, dye or pigment between fibres, within a substrate or between substrates due to capillary forces. NOTE - Migration may occur in textile
32、processing, testing, storage and use. 3.3 pigment: Colorant in particulate form which is insoluble in a substrate, but which can be dispersed in the substrate to modify its colour. 3.4 pad: Impregnation of a substrate (usually fabric) with a liquor, followed by squeezing between rollers. 1 STD-BSI B
33、S EN IS0 105-ZOb-ENGL 2000 3624b67 0905b23 721 EN IS0 105-206:2000 4 Principle Fabric impregnated with test colorant alone, or with test colorant and migration inhibitor, is dried.while partially covered with a watch glass, permitting differential drying and therefore, migration to occur. The degree
34、 of migration is evaluated by visual examination or by reflectance measurements of the covered and uncovered areas. NOTES 1 When drying conditions are not constant and/or uniform, uneven migration may occur, causing shade variations during a run, or shade differences between the face and back, or be
35、tween the side and centre of the fabric. 2 The pad liquor composition may be modified by varying the amount or type of migration inhibitor and tested in the laboratory prior to the application on the range. The colorant concentration, the fabric and the wet pickup should be the same in the laborator
36、y as used on the range. It is then possible to correlate the test results with the improvement experienced in practice. Two procedures are described: Procedure A. The fabric assembly is allowed to dry at room temperature. The procedure is very simple, but time- consuming (overnight). Procedure B. Th
37、e fabric assembly is dried in a laboratory dryer or oven, either with, or without air circulation. This procedure is faster but somewhat more complicated than procedure A. 5 Apparatus and materials 5.1 Fabric pieces for dyeing. NOTE - For disperse dyes, vat dyes and pigments, generally the preferred
38、 fabric is a blend of 65 %:35 % (mh) polyester: cotton gabardine or heavy twill, heat set, bleached and mercerized. For soluble dyes with affinity to cellulose (e.g. reactive dyes), the preferred fabric is a bleached and mercerized 100 % cotton gabardine or heavy twill. However, any other fabric int
39、ended for use on a continuous dye range may be chosen. 5.2 Balance, capable of weighing to an accuracy of 1 mg. 5.3 Laboratory padder. 5.4 Glass plate, 350 mm x 600 mm, for procedure A. 5.5 Watch glasses, 90 mm diameter with 22 mm arch punch. 5.6 Laboratory pin frame, for procedure B. 5.7 Aluminium
40、rings, 110 mm outer diameter, 80 mm inner diameter, 1 mm thickness, for procedure B. 5.8 Clips, e.g. metal binder clips for procedure B. 5.9 Laboratory dryer or oven, for procedure B. 5.10 Grey scale for assessing change in colour, in accordance with IS0 105-A02. 5.11 Spectrophotometer, for reflecta
41、nce measurements. 6 Test specimen Colorant(s), migration inhibitor, thickening agent and other auxiliaries (e.g. electrolyte for reactive dyes) in desired concentration(s) to be tested as appropriate.

42、It is the users responsibility to use safe and proper techniques in handling materials in this test method and to follow good laboratory practices. Consult manufacturers for specific details, such as material safety data sheets and other manufacturers recommendations. Users should also comply with a
43、ny national and local safety regulations. 7.1 Procedure A Cut a 150 mm x 300 mm piece of fabric (5.1), weigh it using the balance (5.2) and then pad it using the laboratory padder (5.3) at (20 f 2) OC. If other padding temperatures are used, these shall be stated in the test report. Generally the we
44、t pickup is 60 % by mass, but may be adjusted to simulate wet pickup of a particular fabric to be run on a particular range. The pad bath contains colorants and usually, auxiliaries. NOTE - Observe padder safety. Normal safeguards on padders should not be removed. Ensure that there is an adequate gu
45、ard at the roller nip point. A foot-operated kick-off is recommended. Obtain the desired wet pickup by adjusting the pressure at the nip of the pad rolls. Calculate the percent wet pickup as the mass gained by the substrate after padding using the following equation: WP = 1 O0 x (% - I where WP ml m
46、o is the percent mass wet pickup; is the mass of the fabric after padding; is the mass of the fabric before padding. Immediately after padding place the fabric on a flat glass plate (5.4). Place the watch glass (5.5) on the fabric as shown in figure 1, and leave the fabric to dry at room temperature
47、. Remove the watch glass and determine the degree of migration in accordance with clause 8 by comparing the dye concentration in the area of the fabric which was covered by the watch glass to the dye concentration in the area of the fabric which was not covered.

49、20 mm) to fit a Laboratory pin frame (5.6). Immediately after padding mount the fabric taut on the pin frame (5.6), sandwiched between two watch glasses (5.5), one on the fabric face and one directly underneath on the back of the fabric. Hold the watch glasses in place with two aluminium rings (5.7) and clips (5.8) as shown in figure 2. Dry the fabric assembly horizontally at (100 f 2) “C for approximately 7 min (or until dry) in a laboratory dryer or oven (5.9). Remove the watch glasses and remove the fabric from the pin frame.
