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 comp

7、onent is dissolved from 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 gener

8、al information should be 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 s

9、tated and described in 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 s

10、alts and other water-soluble 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-s

11、oluble matter is given 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 o

12、f the reagent on the soluble 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 If it is impossible to remove such added matter, the methods are no longer applicable.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

13、in dyed fibre is considered 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

14、 the dry mass of analytical 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 1833-14:2011-01 Provisions have been made for recalculating results on the basis of a) permissible deviations agreed upon for moistur

15、e content1)b) permissible 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

16、 fibre. In some methods, 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 analy

17、sis, the result should be 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 und

18、egraded fibres. If the fibres 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. B

19、efore the analyses are carried 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 te

20、chnically possible. Where 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.

DIN EN ISO 1833-14:2011-01 EN ISO 1833-14:2010 (E) 41 Scope This part of ISO 1833 specifies a method, using acetic acid, to determine the percentage of

43、 acetate, after removal of non-fibrous matter, in textiles made of mixtures of acetate and certain chlorofibres or after-chlorinated chlorofibres. 2 Normative references The following referenced documents are indispensable for the application of this document.

44、cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. 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 glaci

45、al acetic acid. The residue is collected, washed, dried and weighed; its corrected mass is expressed as a percentage of the dry mass of the mixture. The percentage of acetate is found by the difference. 4 Reagents Use the reagents described in ISO 1833-1 together with that given in 4.1. 4.1 Glacial

46、acetic acid, distilling at 117 C to 119 C. SAFETY PRECAUTIONS The harmful effects of this reagent shall be borne in mind, and full precautions shall be taken during use. 5 Apparatus Use the apparatus described in ISO 1833-1 together with those given in 5.1 and 5.2. 5.1 Conical flask, minimum capacit

DIN EN ISO 1833-14:2011-01 EN ISO 1833-14:2010 (E) 56 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 100 ml of glacial acetic acid per gram of specimen

48、. Insert the stopper and shake the flask for 20 min on the mechanical shaker. Decant the supernatant liquid through the weighed filter crucible. Repeat the treatment twice using 100 ml of fresh reagent each time, making three extractions in all. Transfer the residue to the filter crucible, drain usi

49、ng suction, and rinse the crucible and residue with 100 ml of acetic acid and then three times with water. After each rinse, allow the liquor to drain through the crucible for 2 min before draining using suction. Finally, 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.
