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, governmen

    23、tal 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 International Standards adopted by the technical committees are circulated to the mem

    24、ber bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO105-X14 was prepared by Technical Committee ISO/TC38, Textiles, Subcommittee SC1, Tests for coloured textiles and colorants. This third edit

    25、ion cancels and replaces the second edition (ISO 105-X14:1987), of which it constitutes a minor revision. ISO 105 was previously published in thirteen “parts”, each designated by a letter (e.g.“Part A”), with publication dates between1978 and1985. Each part contained a series of “sections”, each des

    26、ignated 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 ISO105-A01.iv bl

    27、ankEN ISO105-X14:1997 BSI 09-1999 1 1 Scope This part of ISO105 specifies a method for determining the resistance of the colour of wool in all forms to acid chlorination using sodium dichloroisocyanurate 1) . This simulates the manufacturing operation in which a liquid containing or liberating activ

    28、e chlorine under mildly acid conditions is used for imparting shrink-resistant properties to wool in textiles. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO105. At the time of publication, the editio

    29、ns 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 recent editions of the standards indicated below.

    31、silver. 3 Principle A specimen of the textile is treated in a formic acid buffer solution to which solutions of sodium dichloroisocyanurate and sodium hydrogensulfite are added successively, and is then rinsed and dried. The change in colour of the specimen is assessed by comparison with the grey sc

    32、ale. 4 Apparatus and reagent 4.1 Grade 3 water (see ISO105-A01:1994, sub-clause8.1), both for making up solutions and for use by itself. 4.2 A freshly prepared aqueous solution containing3,0g of anhydrous sodium formate per litre and an amount of sodium dioctylsulfosuccinate wetting agent equivalent

    33、 to0,5g of the solid per litre, and buffered to pH4,0 0,2 with formic acid (approximately1g of90% formic acid is required per litre). To avoid difficulties in dissolving the sodium dioctylsulfosuccinate, either pipette 0,83 ml of a60% (or8,3ml of the60% solution diluted tenfold) per litre of final v

    34、olume into the previously prepared solution of formate, made up to approximately90% of the final volume; or dissolve each 0,5g of the solid sodium dioctylsulfosuccinate in100ml of water by bringing to the boil, then add to the formate solution, previously made up to approximately80% of the final vol

    35、ume. In both cases, after adding the sodium dioctylsulfosuccinate, add formic acid to adjust the pH and make up to final volume. The final solution is often slightly cloudy. 4.3 A freshly prepared aqueous solution containing11,27g of sodium dichloroisocyanurate dihydrate (C 3 N 3 O 3 Cl 2 Na.2H 2 O)

    36、 per litre. Sodium dichloroisocyanurate dihydrate with a typical available chlorine content on a mass basis of55% should preferably be used;11,27g of this is equivalent to10,0g of commercial anhydrous product with62% available chlorine. The amount of any other sodium dichloroisocyanurate formulation

    37、 used should be adjusted to be equivalent in terms of available chlorine. Pure sodium dichloroisocyanurate contains32,24% chlorine, all of which is hydrolysed to oxidizing hydrochlorous acid, so the available chlorine is twice this, or64,48% (unlike the case of chlorine gas, where available chlorine

    38、 and chlorine content are the same because only half of the molecule is converted to hypochlorous acid). 4.4 A freshly prepared aqueous solution of sodium hydrogensulfite containing3,29g of NaHSO 3per litre, prepared by dissolving3,0g of sodium metabisulfite (Na 2 S 2 O 5 ) in1litre of water. 4.5 Eq

    39、uipment ensuring continuous agitation of the test specimen, its complete immersion at a liquor ratio of47:1, no overflow of liquor during agitation at a liquor ratio of60:1, and ready access to the specimen. 1) 1,3-dichloro-1,3,5-triazine-2,4,6(1H, 3H, 5H)-trione sodium salt.EN ISO105-X14:1997 2 BSI

    40、 09-1999 The equipment should permit continuous agitation and immersion of the specimen in the test solution, especially immediately after the sodium dichloroisocyanurate solution is added. Ready access to the specimen is required so that it may be manipulated easily and quickly, for example tamped

    41、with a flattened glass rod to help in wetting out, or temporarily raised above the liquor level to prevent direct contact with the concentrated sodium dichloroisocyanurate solution. Suitable apparatus is a) a device allowing the specimen to reciprocate in a vertical direction whilst immersed continu

    42、ally in the solution; b) a device in which the vessel contents (the test solution and the specimen) are agitated; c) a device with a hand-stirrer. 4.6 Electronic pH meter, preferably, or narrow-range pH-indicator paper. 4.7 Starch-iodide test paper 4.8 Grey scale for assessing change in colour, comp

    43、lying with ISO105-A02. 5 Test specimen 5.1 The specimen shall be air-dry under laboratory conditions. The content of dichloromethane-extractable matter, determined in accordance with ISO3074, shall not exceed0,5%, calculated with respect to the original mass of the conditioned specimen (especially i

    44、f testing to specify dye fastness), or, if testing for suitability for bulk processing, shall be typical, after appropriate pretreatments, of the bulk to be processed. 5.2 It may be found advantageous for the mass of the test specimen to be a multiple of0,5g, i.e.2,0g or more. 5.3 The rib of section

    45、 and the body section of a garment shall be tested separately. 5.4 If the textile to be tested is yarn, knit it into plain fabric, or test it in hank form. 5.5 If the textile to be tested is loose fibre, comb and compress some of it into a sheet, of preferred minimum dimensions40mm 100mm. Place the

    46、sheet on a lightweight undyed polyester fabric of the same size and sew the two together with stitching round the edges. Use a method of agitation (see4.5) that does not cause the composite specimen to disintegrate or, if this is not possible, use a composite specimen incorporating an additional she

    47、et of light-weight undyed polyester fabric of open structure, with the test specimen sandwiched between the two sheets of polyester fabric. 6 Procedure 6.1 Carry out the operations described in6.2 to6.8 inclusive, treating each specimen in a separate bath. 6.2 Constant stirring or other agitation is

    48、 required throughout the test and is particularly important immediately after adding the sodium dichloroisocyanurate solution (4.3) and sodium hydrogensulfite solution (4.4). 6.3 For each gram of mass of the specimen, use47ml of the formic acid buffer solution (4.2) at pH 4,0 0,2, immerse the specim

    49、en at an initial temperature of 25 C 2 C, wet out thoroughly, then keep agitated in this solution for at least10min. Adequate wetting out is extremely important, especially if the materials have not been scoured previously (see10.4 of ISO105-A01, but note that kneading by hand is not suitable for this test). 6.4 For each gram mass of the specimen, add3,0ml of the sodium dichloroisocyanurate solution (4.3) at25 C 2 C, carefully but rapidly, interrupting agitation as little as possible and minimizing direct contact of
