21、9 Foreword ISO (the International Organization for Standardization) 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
22、 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 in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matte
23、rs of electrotechnical standardization. Draft International Standards adopted by the technical 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 ISO105-Z07
24、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 between 1978 and 1985. Each part contained a series of “section
25、s”, 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 designations. A complete list of these parts is given in ISO1
26、05-A01. Annex A of this part of ISO105 is for information only. Descriptors: Textiles, dyeing, colour fastness, dyes, tests, colour fastness tests, determination, solubility.ENISO 105-Z07:1997 BSI 04-1999 1 1 Scope This part of ISO105 describes a method for the determination of the application solub
27、ility of water-soluble dyes in the range 40 C to 90 C and of their solution stability. The method is not intended to measure absolute solubility. NOTE 1Several factors which may influence test results are listed in Annex A. 2 Normative references The following standards contain provisions which, thr
28、ough reference in this text, constitute provisions of this part of ISO105. At the time of publication, the editions indicated were 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 r
29、ecent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 1773:1976, Laboratory glassware Boiling flasks (narrow-necked). ISO 3696:1987, Water for analytical laboratory use Specification and test methods. 3 Principle Se
30、veral solutions of known concentration, including the solubility limit, of the dye to be tested are prepared at a specified temperature. The solutions are then filtered under suction at this temperature in a heatable Nutsch filter and the application solubility limit determined by visual assessment
31、of the filter residues and the measured flow-through time of the filtrate. The application solubility of dyes is normally determined at 90 C. For certain classes of dyes the solubility is determined at a lower temperature. In selecting the test temperature, the manufacturers recommendations are foll
32、owed. The temperature is indicated in the test report (e.g.application solubility limit determined at 90 C, 60 C, etc.). The solution stability of dyes is determined by storing for 2h and, as the case requires, cooling the above-mentioned solution before filtration and assessment. The dissolving and
33、 storage temperatures are indicated in the test report (e.g.solution stability at 90 C/60 C, 60 C/60 C, etc.). 4 Apparatus and reagents 4.1 Erlenmeyer flask, wide-mouthed, capacity500ml, complying with ISO1773. 4.2 Heating bath, thermostatically controlled, with magnetic stirring bar 40mm long by 6m
34、m diameter, speed of stirrer 500r/min to 600r/min. 4.3 Water bath, with temperature regulator (heating/cooling) for adjusting the storage temperature (e.g.60 C, 30 C or 25 C). 4.4 Nutsch filter (Bchner funnel), heatable, of glass, steel or porcelain, of inner diameter 70mm, capacity at least 200ml,
35、having more than 100holes with a total surface area of holes (evenly distributed) of not less than 200mm 2 . 4.5 Thermostatic device (optional), with circulation pump to adjust temperature of Nutsch filter. 4.6 Vacuum apparatus 4.6.1 Suction bottle, capacity 1 litre to 2 litres. 4.6.2 Piston or memb
36、rane pump, of sufficiently high suction capacity to create a full vacuum of at least 50kPa under pressure. 4.6.3 Apparatus to adjust and maintain a given vacuum, preferably coupled with a manometer. 4.7 Stopwatch, to measure flow-through time. 4.8 Filter paper, circular, 70mm 2mm diameter.

An amount of 200ml is designated as normal. More water may be add
39、ed to the solution, but such additions shall be reported together with the dye solubility values. NOTE 3No account is taken of changes in volume as a function of temperature, or those caused by the addition of dye. 5 Preparation of solutions 5.1 The concentrations at which the dye solutions are prep
40、ared shall be chosen considering the expected application solubility limit of the dye: 5.2 To determine solubility at 90 C, paste a known amount of the test dye and introduce it into the wide-mouthed Erlenmeyer flask (4.1) with a portion of the 200ml water (4.9) at about 60 C, but not in excess of t
41、he dissolving temperature of the dye. When the dye is completely wetted out, add the rest of the water to the flask. Place this solution into the heating bath (4.2) maintained at 95 C. Switch on the magnetic stirrer. When the solution has attained a temperature of95 C 2 C, continue stirring at this
42、temperature for a further 5min (total stirring time approximately 10min). Then filter the solution (seeclause 6) immediately to determine the solubility of the dye at 90 C. Repeat the process for each concentration of dye under test. 5.3 To determine solubility at temperatures below 90 C, paste a kn
43、own graduated amount of the test dye and introduce it into a wide-mouthed Erlenmeyer flask with a portion of the 200ml water(4.9) at the desired dissolving temperature until the dye is completely wetted out. Then add the rest of the water to the flask. Place the solution in the heating bath maintain
44、ed at the desired dissolving temperature; stir the solution for 10 min and then filter (seeclause6). Repeat the process for each concentration of dye under test. 5.4 To determine the solution stability at the desired temperature (e.g. 60 C, 30 C or 25 C), place the Erlenmeyer flask with the solution
45、 prepared according to 5.1 or 5.2 into a bath maintained at the desired temperature (see4.3) and allow to stand for 2h before filtration. Before filtering, mix the solution thoroughly by tilting the flask to and fro. 6 Filtering the solutions NOTE 4In order to avoid any temperature shock effects, it
46、 is essential that heated solutions are filtered through equipment already brought to the same temperature as the solution under test. Ideally this is best done using a jacketed filter funnel, but acceptable results can also be obtained using preheated funnels, either by immersion in a water bath or
47、 oven, or by passing water preheated to the test temperature through the equipment immediately prior to carrying out the test. When using this latter technique, the amount of water should be determined locally in order that the filter funnel can be heated to the same temperature irrespective of its
48、geometry and the ambient conditions. In all cases when using preheating techniques rather than a jacketed funnel, the test solution should be passed through the test equipment immediately after removing it from its heating medium. 6.1 Preheat the Nutsch filter (4.4) to the test temperature and maint
49、ain at this temperature throughout the entire filtration operation. 6.2 Immediately before filtering, wet out two filter papers (4.8) in the Nutsch filter in a double layer using at least 50ml water at the test temperature. 6.3 Adjust the vacuum (4.6) to 3kPa to 4kPa, which is equivalent to 300mm to 400mm water column pressure. 6.4 Filter the dye solution obtained as in 5.1, 5.2 or5.3 at the recommended temperature and measure the flow-through time with a stopwatch. Visually examine the flask which contain
