7、(E) ISO 2006 All rights reserved iiiForeword 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 i
8、nterested 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 in the work. ISO collaborates closely with the International Electrotechn
9、ical 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 prepare International Standards. Draft International Standards adopted by th
10、e 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.

22、f mixtures of natural and regenerated cellulose fibres and polyester fibre. 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 edition of the refere
23、nced document (including any amendments) applies. ISO 1833-1, Textiles Quantitative chemical analysis Part 1: General principles of testing 3 Principle The cellulose fibre is dissolved out from a known dry mass of the mixture, with 75 % (mass fraction) sulfuric acid. The residue is collected, washed
24、, dried and weighed; its mass is expressed as a percentage of the dry mass of the mixture. The proportion of cellulose fibre is found by the difference. 4 Reagents Use the reagents described in ISO 1833-1 together with those given in 4.1 and 4.2. 4.1 Sulfuric acid, 75% (mass fraction). A suitable re
25、agent can be prepared by adding carefully, while cooling, 700 ml of concentrated sulfuric acid ( 1,84 g/ml) to 350 ml of distilled water. After the solution has cooled to room temperature, dilute it to 1 I with water. The concentration is not critical within the range 73 % to 77 % (mass fraction) su
26、lfuric acid. 4.2 Ammonia, dilute solution. Dilute 80 ml of concentrated ammonia solution ( 0,880 g/ml) to 1 I with water. ISO 1833-11:2006(E) 2 ISO 2006 All rights reserved5 Apparatus Use the apparatus described in ISO 1833-1 together with those given in 5.1 and 5.2. 5.1 Conical flask, minimum capac
27、ity 500 ml, glass-stoppered. 5.2 Heating apparatus suitable for maintaining the temperature of the flask at (50 5) C. 6 Test procedure Follow the general procedure given in ISO 1833-1, and then proceed as follows. To the specimen contained in the conical flask, add 200 ml of sulfuric acid per gram o
28、f specimen. Insert the stopper and shake the flask carefully to wet out the specimen. Maintain the flask at (50 5) C for 1 h, shaking the flask and contents gently at intervals of about 10 min. Filter the contents of the flask through the weighed filter crucible using suction. Transfer any residual
29、fibres to the crucible by washing out the flask with a little more sulfuric acid. Drain the crucible using suction, and wash the residue on the filter once by filling the crucible with a fresh portion of sulfuric acid. Do not apply suction until the crucible has drained under gravity or stood for 1
30、min. Wash the residue successively several times with cold water, twice with dilute ammonia solution, and then thoroughly with cold water, draining the crucible using suction after each addition. Do not apply suction until each washing liquor has drained under gravity. Finally, drain the crucible us
31、ing suction, dry the crucible and residue, then 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 1,00. 8 Precision On a homogeneous mixture of textile materials, the confidence limits of the results obtained by this method are not greater than 1 for the confidence level of 95 %.
