The work of preparing International Standards is no
23、rmally carried out through ISO 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 committee. International organizations, governmental and non- governmental, in liaison with ISO, also take part i
24、n the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard
25、 requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 105-Z06 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. ISO 105 was previously published in thirteen “parts”, each designated by
26、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 (e.g. “Section A01)”). These sections are now being republished as separate documents, themselves designat
27、ed “parts” but retaining their earlier alphanumeric designations. A complete list of these parts is given in ISO 105-A01. Annex A of this part of ISO 105 is for information only.

28、 BSI LANOITANRETNI DRADNATS OSI)E(8991:60Z-501 OSI 1 Textiles Tests for colour fastness Part Z06: Evaluation of dye and pigment migration 1 Scope This part of ISO 105 describes a method for assessing the migration propensity of a pad liquor system containing dyes or pigments, subsequently referred t
29、o 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 of different t
30、ypes 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, constitutes provisions
31、 of this part of ISO 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 ISO 105 are encouraged to investigate the possibility of applying the most recent edition of the standard listed below. Members
32、 of IEC and ISO maintain registers of currently valid International Standards. ISO 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 ISO 105, the following definitions apply. 3.1 dye: Colorant appl
33、ied to or formed on a substrate, via the molecularly dispersed state, which exhibits some degree of permanence. 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 processing, test
34、ing, 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.

36、ntial drying and therefore, migration to occur. The degree 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
37、run, or shade differences between the face and back, or between 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 fab
38、ric and the wet pickup should be the same in the laboratory 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 ver
39、y simple, but time- consuming (overnight). Procedure B. The 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 dispe
40、rse dyes, vat dyes and pigments, generally the preferred fabric is a blend of 65 %:35 % (m/m) 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 % cotto
41、n gabardine or heavy twill. However, any other fabric intended 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.
42、5.6 Laboratory pin frame, for procedure B. 5.7 Aluminium 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 accordan
43、ce with ISO 105-A02. 5.11 Spectrophotometer, for reflectance 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.

Consult manufacturers
45、for specific details, such as material safety data sheets and other manufacturers recommendations. Users should also comply with any national and local safety regulations. 7.1 Procedure A Cut a 150 mm 300 mm piece of fabric (5.1), weigh it using the balance (5.2) and then pad it using the laboratory
46、 padder (5.3) at (20 2) C. If other padding temperatures are used, these shall be stated in the test report. Generally the wet 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, auxil
47、iaries. NOTE Observe padder safety. Normal safeguards on padders should not be removed. Ensure that there is an adequate guard 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
48、wet pickup as the mass gained by the substrate after padding using the following equation: WP = 1001 1 0 m m where WPis the percent mass wet pickup; m1is the mass of the fabric after padding; m0is the mass of the fabric before padding. Immediately after padding place the fabric on a flat glass plate
49、 (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. 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.
