The work of prepari

17、ng International Standards is normally 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 lia

18、ison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of

19、technical committees is to prepare International Standards. 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. Attention is

20、drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

31、O 1833 specifies a method, using sodium zincate, to determine the percentage of viscose, cupro or modal fibre, after removal of non-fibrous matter, in textiles made of binary mixtures of viscose or most of the current cupro or modal fibres and raw, scoured, kiered or bleached cotton. Where a cupro o

32、r modal fibre is present, a preliminary test should be carried out to see whether it is soluble in the reagent. The method is not applicable to mixtures in which the cotton has suffered extensive chemical degradation, nor when the viscose, cupro or modal fibre is rendered incompletely soluble by the

33、 presence of certain permanent finishes or reactive dyes that cannot be removed completely. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest editi

ISO 1833-1, Textiles Quantitative chemical analysis Part 1: General principles of testing 3 Principle The viscose, cupro or modal fibre is dissolved from a known dry mass of the mixture, with sodium zincate solution. The residue is co

35、llected, washed, dried and weighed; its corrected mass is expressed as a percentage of the dry mass of the mixture. The percentage of viscose, cupro or modal fibre is found by the difference.

36、in ISO 1833-1 together with those given in 4.1, 4.2, 4.3 and 4.4. 4.1 Sodium zincate (stock solution). Determine the NaOH content of sodium hydroxide pellets and dissolve the equivalent of 180 g of NaOH in 180 ml to 200 ml of water. Stir the solution continuously with a mechanical stirrer, and add g

37、radually 80 g of zinc oxide of analytical reagent quality, at the same time gradually heating the solution. When all the zinc oxide has been added, heat the solution until it boils gently; continue boiling the solution until it becomes clear or only slightly turbid, then cool it, add 20 ml of water,

38、 stir thoroughly, cool to room temperature, and make up to 500 ml with water in a graduated flask. Filter the solution through a sintered glass filter, with pore size 40 m to 90 m, before use. 4.2 Sodium zincate, dilute solution (working solution). To 1 volume (accurately measured) of stock sodium z

39、incate solution add, while stirring, 2 volumes of water. Mix thoroughly, and use within 24 h of preparation. 4.3 Ammonia, dilute solution. Dilute 200 ml of concentrated ammonia solution ( = 0,880 g/ml) to 1 I with water. 4.4 Acetic acid, dilute solution. Dilute 50 ml of glacial acetic acid to 1 I wi

40、th water. 5 Apparatus Use the apparatus described in ISO 1833-1 together with those given in 5.1, 5.2 and 5.3. 5.1 Mechanical shaker. 5.2 Mechanical stirrer. 5.3 Conical flask, minimum capacity 500 ml, glass-stoppered. 6 Test procedure Follow the general procedure given in ISO 1833-1, and then proce

41、ed as follows. To the specimen contained in the conical flask, add 150 ml of freshly prepared dilute sodium zincate solution per gram of specimen. Insert the stopper and shake the flask vigorously on the mechanical shaker for (20 1) min. Filter the contents of the flask through the weighed filter cr

42、ucible. Apply suction to the crucible to remove excess liquor, again replace the residue in the flask by means of forceps, add 100 ml of ammonia solution, and shake the flask for 5 min on the mechanical shaker. Filter the contents of the flask through the same weighed filter crucible and wash any fi

43、bres from the flask into the crucible with water. Wash the crucible and residue with 100 ml of acetic acid solution, and then thoroughly with water. Do not apply suction until each washing liquor has drained under gravity. Finally, drain the crucible using suction, dry the crucible and residue, then

44、 cool and weigh them.
