International organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electr

Publication as an International Standard requires approval by at least75% of the member bodies casting a v
23、ote. International Standard ISO105-Z03 was prepared by Technical Committee ISO/TC38, Textiles, Subcommittee SC1, Tests for coloured textiles and colorants. ISO105 was previously published in thirteen “parts”, each designated by a letter (e.g.“Part A”), with publication dates between1978 and1985. Eac
24、h part contained a series of “sections”, each designated by the respective part letter and by a two-digit serial number (e.g.“SectionA01”). These sections are now being republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric designations. A complete
25、list of these parts is given in ISO105-A01. Descriptors: Textiles, acrylic fibres, dyeing, colour fastness, dyes, tests, colour-fastness tests, compatibility.ENISO105-Z03:1998 BSI 04-1999 1 1 Scope This International Standard specifies a method for determining the behaviour of a basic dye in relatio
26、n to its compatibility with other basic dyes when applied to acrylic fibres in the presence of those basic dyes. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this part of ISO105. At the time of publication, the editi
27、on indicated was valid. All standards are subject to revision, and parties to agreements based on this part of ISO105 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid Intern
28、ational Standards. ISO3696:1987, Water for analytical laboratory use Specification and test methods. 3 Principle In the dyeing of acrylic fibres with basic dyes, the classic parameters, e.g.the time of half-dyeing, of individual dyes do not give a true indication of their dyeing behaviour in admixtu
29、re with other basic dyes. Since, under normal dyeing conditions, basic dyes show virtually no migration in acrylic fibres, compatibility is of major importance in selecting dye combinations with optimum, level, dyeing behaviour. Compatibility is assessed against one of two defined five-step scales:
30、a yellow scale and a blue scale. The assessments are made using the scale showing the greatest difference in hue from that of the dye undertest. The compatibility value of the dye is assessed by determining its dyeing behaviour in combination with each of a series of reference dyes in the relevant s
31、cale. NOTEThe recommended reference dyes have been chosen because a) they form two series encompassing the compatibility behaviour of nearly all basic dyes recommended for acrylic fibres; b) the dyes in a series are spaced to produce approximately equal visual effects; c) the corresponding reference
32、 dyes from both scales are compatible. 4 Safety precautions NOTEThese safety precautions are for information purposes only. The precautions are ancillary to the test procedures and are not intended to be all-inclusive. It is the users responsibility to use safe and proper techniques in handling mate
33、rials in this test method. Consult manufacturers for specific details such as material safety data sheets and other recommendations. 4.1 Follow good laboratory practice. Wear safety glasses in all laboratory areas and a single-use dust respirator while handling powder dyes. 4.2 Handle all chemicals
34、with care. 4.3 Use chemical goggles or a face shield, impervious gloves and an impervious apron during handling of concentrated acetic acid. 4.4 Ensure that an eyewash/safety shower is located nearby and an organic-vapour respirator with full face-piece is readily available for emergency use. 4.5 Th
35、e basic dyes listed in this method belong to the following classes: 4.6 Any national and local safety regulations should also be complied with. 5 Apparatus and materials During the test, use only reagents of recognized analytical grade and only grade3 water as defined in ISO3696. 5.1 Apparatus for d
36、yeing at a40 : 1 liquor : goods ratio at the required constant temperature. 5.2 Reference dyes 1) . The constitution of the scales, and the recommended amounts of reference dyes to be used in the test, are shown in Table 1. The percentages given produce dyeings approximately1/2 of1/1 standard depth

39、9 Table 1 Reference dyes NOTEFor ease of visual assessment, it is recommended that the dyes under test and the reference dyes be used in a concentration which produces approximately1/2 of 1/1 standard depth when dyed on most acrylic fibres. It should be understood, however, that it is not critical t
40、hat the compatibility is assessed at standard depth, since identical values are obtained at other depths and in other ratios of reference and test dyes. 5.3 Acetic acid, glacial. 5.4 Sodium acetate crystals (CH 3 COONa3H 2 O). 6 Procedure 6.1 Prepare20 to30 specimens (four to six for each dyebath),
41、all of equal mass, each specimen consisting of one piece or skein of the acrylic fibre used for the test. 6.2 Pretreat the specimens of material to be used in the test for10min at approximately95 C in an aqueous solution containing1% (omf) of glacial acetic acid(5.3) and1% (omf) of sodium acetate cr
42、ystals (5.4) (to give a pH-value of4,5 0,2) at a liquor : goods ratio of40 : 1. Then lightly squeeze the material out and keep it wet ready for use. 6.3 Set five dyebaths, one for each of the reference dyes, at95 C, a liquor : goods ratio of40 : 1 and apH-value of4,5 0,2 with X % (omf) of the approp
43、riate reference dye (blue or yellow), Y % (omf) of the dye under test, 1% (omf) glacial acetic acid(5.3), 1% (omf) sodium acetate crystals(5.4), where Y corresponds to the amount of dye under test required to give a dyeing approximately1/2 of1/1 standard depth on the acrylic fibre chosen and X is as
44、 given in Table 1. NOTEThese percentages and the liquor: goods ratio refer to the mass of an individual specimen as defined, i.e.to one skein or piece, and not to the combined mass of the four to six specimens required for each dyebath. 6.4 Four to six specimens of material are needed for each dyeba
45、th. Proceed with each of the prepared dye-baths as follows: Enter the first specimen into the dyebath at the required temperature for the required time at this temperature (see note1). Remove this specimen of material and dye the second specimen in the same way as the first. Repeat this procedure wi
46、th the remaining two to four specimens, except that the last specimen shall be dyed to complete exhaustion. NOTE 1Acrylic fibres can vary widely in their dyeing characteristics. The test is conducted in such a manner that all available dye is exhausted in approximately equal portions on to each of t
47、he five specimens used. In order to accomplish this, it may be necessary to adjust the dyeing temperature within the range90 C to100 C and/or the dyeing time for each specimen within the range5min to10min. NOTE 2The test is valid only under the conditions defined. Compatibility values may be affecte
48、d by the presence of anionic substances e.g.anionic surfactants or anionic dyes in the dyebath. NOTE 3The yellow and blue reference dyes of compatibility value 2,0 are not fully compatible when applied in combination. The differences observed are exaggerated if wet-spun acrylic fibres are used. NOTE
49、 4It should be clearly understood that the test is one for compatibility and not a measure of the extent to which incompatibility may lead to unlevelness when combinations of basic dyes are applied to acrylic fibres. 6.5 Rinse in grade3 water and dry each specimen immediately after it is removed from the dyebath. Mount the specimens in the sequence in which they were dyed.
