6、xtilchemische Prfver-fahren und Fasertrennung. The Introduction of ISO 1833-1 is summarized below as a help to users of this standard: In general, the methods described in the various parts of ISO 1833 are based on the selective solution of an individual component. Once a component is dissolved from

7、 a test specimen, the insoluble residue is weighed and the percentage of the soluble component(s) is calculated from loss in mass. ISO 1833-1 gives information that is common to all of these analytical methods for all fibre mixtures, regardless of their composition. This general information should b

8、e used when applying the other parts of the ISO 1833 series; each of these parts contains a more detailed description of a method that is applicable for a specific fibre mixture. If one of these methods is based on a principle other than selective solution, this is expressly stated and described in

9、detail in the respective part of the standards series. Fibre mixtures used during processing and, to a lesser extent, in finished textiles may contain fats, waxes or dressings which either occur naturally or are added to facilitate processing. Fibre mixtures may also contain salts and other water-so

10、luble matter. Some or all of these substances can separate during analysis and be erroneously calculated as soluble fibre components. To avoid this error, non-fibrous matter should be removed before analysis. A method of pre-treatment for removing oils, fats, waxes and water-soluble matter is given

11、in ISO 1833-1:2006, Annex A. In addition, textiles may contain resins or other matter added to bind the fibres or to confer special properties, such as water repellence or crease resistance. Such matter, including dyestuffs in exceptional cases, may interfere with the action of the reagent on the so

12、luble components and/or may be partially or completely removed by the reagents. This type of added matter can thus also cause errors and should be removed before the sample is analysed. If it is impossible to remove such added matter, the methods are no longer applicable. Dye in dyed fibre is consid

13、ered to be an integral part of the fibre and is not removed. Most textile fibres contain water, the amount of which depends on the type of fibre and the relative humidity of the ambient air. These analyses are conducted on the basis of dry mass, and a procedure for determining the dry mass of analyt

14、ical samples and residues is given in ISO 1833-1. The result is thus obtained on the basis of the dry mass of the dry fibres only. 2 DIN EN ISO 1833-3:2011-01 Provisions have been made for recalculating results on the basis of a) permissible deviations agreed upon for moisture content1)b) permissibl

15、e deviations agreed upon for humidity, as well as for 1) the fibrous matter separated during pre-treatment, and 2) non-fibrous matter (e.g. dressings, processing oils or sizing assistants) which can be considered as being a commonly used commercial article that is part of the fibre. In some methods,

16、 the insoluble components of a mixture may be partially dissolved in the reagent used to dissolve the soluble component(s). Whenever possible, reagents have been chosen that have little or no effect on the insoluble fibres. If a loss in mass is known to occur during the analysis, the result should b

17、e corrected; correction factors are given for this purpose. These factors have been determined in several laboratories by treating, with the appropriate reagent as specified in the method of analysis, fibres cleaned by pre-treatment. These correction factors apply only to undegraded fibres. If the f

18、ibres have been degraded during processing, different correction factors may be necessary. The methods described in this series apply for single determinations; at least two determinations should be made on separate samples, further determinations can be made where desired. Before the analyses are c

19、arried out, all fibres in the mixture should be identified. For the purposes of confirmation, it is recommended that alternative methods be used in which the component that would have made up the residue when using the standard method is dissolved first, unless this is not technically possible. Wher

20、e practically possible, the components of a mixture are to be manually separated if the method described in ISO 1833-1:2006, Annex B is to be primarily used instead of the chemical analytical methods described in the other parts of ISO 1833.

ISO 1833-1, Textiles Quantitative chemical analysis Part 1: General principles of testing 3 Principle The acetate is dissolved out from a known dry mass of the mixture, with acetone. The residue is collected, washed, dried and weighed;

46、its mass, corrected if necessary, is expressed as a percentage of the dry mass of the mixture. The percentage of acetate is found by difference. 4 Reagents Use the reagents described in ISO 1833-1 together with that described in 4.1. 4.1 Acetone, distilling between 55 C and 57 C. 5 Apparatus Use the

47、 apparatus described in ISO 1833-1 together with that described in 5.1. 5.1 Conical flask, minimum capacity 200 ml, glass-stoppered. 5DIN EN ISO 1833-3:2011-01 EN ISO 1833-3:2010 (E) 6 Test procedure Follow the general procedure described ISO 1833-1, and then proceed as follows. To the specimen cont

48、ained in the conical flask, add 100 ml of acetone per gram of specimen, shake the flask, allow it to stand for 30 min at room temperature, and then decant the liquid through the weighed filter crucible. Repeat the treatment twice more (making three extractions in all), but for periods of 15 min only

49、, so that the total time of treatment in acetone is 1 h. Wash the residue into the filter crucible with acetone, and drain using suction. Refill the crucible with acetone and allow it to drain under gravity. Finally, drain the crucible using 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.
