The work of preparing International Standards is norm
10、ally 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 in t
11、he work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular th
12、e different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this docu
13、ment may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

16、 shrinkage in dry-hot air (after treatment) 1 Scope This International Standard specifies methods for the determination of dry-hot air shrinkage (after treatment) of synthetic filament yarns, skein method and single-end method. The skein method provides two forms of measurement which are of manual a
17、nd automatic types. The single-end method gives the result by manual measurement. In case of dispute, manual measurement procedure is to be used. If these methods are not applicable, the corresponding test methods may be agreed between interested parties. This International Standard is applicable to
18、 synthetic filament yarns of linear density less than 3 000 dtex. This International Standard is not applicable to partially oriented yarns. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For
19、 dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 139, Textiles Standard atmospheres for conditioning and testing 3 Terms and definition For the purposes of this document, the following ter
20、ms and definitions apply. 3.1 shrinkage in dry-hot air (after treatment) decrease in length of a specimen as a result of thermal treatment in dry-hot air, expressed as a percentage of its original length, which measured under tension before and after treatment 4 Principle Under specific condition, a
21、 test specimen is treated in dry-hot air. Shrinkage is calculated as variation in length, measured before and after treatment. 5 Apparatus and materials 5.1 Skein winding reel, which meets the following requirements: a) 1 000 2,5 mm reel circumference, driven either automatically or manually; b) a t
22、raversing mechanism to avert overlapping when several skeins are wound at the same time; c) a tensioning device to maintain tension within the recommended limits, accurate to within 10 %; d) a device to count reel revolutions, preferably capable to stop winding automatically and warn when nearing th
23、e specified number of reel revolutions; INTERNATIONAL ST ANDARD ISO 18067:2015(E) ISO 2015 All rights reserved 1 ISO 18067:2015(E) e) a mechanism to reduce the reel circumference for easy removal of the skein. 5.2 Length-measuring stand, which meets the following requirements: a) a stand for measuri
24、ng specimen length of least 1 mm gauge length; b) a millimetre scale to determine specimen length, accurate to within 1 mm; c) a steel hook or a clamp, where the top of the hook or the lower side of the clamp (where the specimen hung from) is positioned in line with the zero index of the scale; d) t
