The work of preparing International Standards is n
19、ormally 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
20、n 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 technical committees is to prep
21、are 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 drawn to the possibility that s

32、1Textiles Quantitative chemical analysis Part 6: Mixtures of viscose or certain types of cupro or modal or lyocell and cotton fibres (method using formic acid and zinc chloride) 1 Scope This part of ISO 1833 specifies a method, using a mixture of formic acid and zinc chloride, to determine the perce
33、ntage of cotton, after removal of non-fibrous matter, in textiles made of binary mixtures of viscose or some cupro, modal and lyocell fibres, with cotton. If a cupro or modal or lyocell fibre is found to be present, a preliminary test is carried out to see whether it is soluble in the reagent. The m
34、ethod is not applicable to mixtures in which the cotton has suffered extensive chemical degradation, nor when the viscose, cupro, modal or lyocell fibre is rendered incompletely soluble by the presence of certain permanent finishes or reactive dyes that cannot be removed completely. WARNING This par
35、t of ISO 1833 calls for the use of substances/procedures that may be injurious to the health/environment if appropriate conditions are not observed. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety/environment at any stage. 2

37、ative chemical analysis Part 1: General principles of testing 3 Principle The viscose, cupro, modal or lyocell fibre is dissolved out from a known dry mass of the mixture, with a reagent composed of formic acid and zinc chloride. The residue is collected, washed, dried and weighed; its corrected mas
38、s is expressed as a percentage of the dry mass of the mixture. The percentage of viscose, cupro, modal or lyocell fibre is found by difference.

39、ghts reserved4 Reagents Use the reagents described in ISO 1833-1, together with those specified in 4.1 and 4.2. 4.1 Formic acid/zinc chloride reagent. Prepare a solution containing 20 g of anhydrous zinc chloride (minimum assay to be 98 %) and 68 g of anhydrous formic acid, made up to 100 g with wat
40、er. The harmful effects of this reagent should be borne in mind, and full precautions should be taken in its use. 4.2 Ammonia, dilute solution. Dilute 20 ml of concentrated ammonia solution ( 0,880 g/ml) to 1 I with water. 5 Apparatus Use the apparatus described in ISO 1833-1, together with those de
41、scribed in 5.1 and 5.2. 5.1 Conical flask, minimum capacity 200 ml, glass-stoppered. 5.2 Heating apparatus, suitable for maintaining the temperature of the flask at (40 2) C or (70 2) C. 6 Test procedure Follow the general procedure described in ISO 1833-1, and then proceed as follows. Place the spe
42、cimen without delay in the conical flask preheated to 40 C. Add 100 ml of formic acid/zinc chloride reagent per gram of specimen, preheated to 40 C. Stopper the flask and shake it. Allow the flask and contents to remain at 40 C for 2 h 30 min, shaking it twice during this time at intervals of about
43、45 min. In case of difficulties dissolving some man-made fibres at 40 C, apply the same procedure but at 70 C for 20 min. Filter the contents of the flask through the weighed filter crucible and wash any fibres from the flask into the crucible with the reagent. Rinse with a further 20 ml of reagent,
44、 preheated to 40 C. Wash the crucible and residue thoroughly with water at 40 C (or at 70 C when applicable). Rinse the residue with 100 ml of cold ammonia solution, ensuring that the residue remains totally immersed in the solution for 10 min, then rinse with cold water. Do not apply suction until
45、each washing liquor has drained under gravity. Finally, drain the crucible using suction, dry the crucible and residue, and cool and weigh them. 7 Calculation and expression of results Calculate the results as described in the general instructions of ISO 1833-1. The value of d is 1,02 for all types
46、of cotton, except when the temperature of 70 C is applied; then d is 1,03.
