Textiles - Woven fabrics - Construction - Methods of analysis - Part 2: Determination of number of threads per unit length (ISO 7211-2:1984 modified)

This standard specifies methods for determination of number of threads per unit length of woven fabrics.

Textilien - Gewebe - Untersuchungsverfahren - Teil 2: Bestimmung der Anzahl der Fäden je Längeneinheit (ISO 7211-2:1984 geändert)

Der vorliegende Teil von ISO 7211 beschreibt drei Verfahren für die Bestimmung der Anzahl von Fäden je Zentimeter in gewebten Flächengebilden. Jede der drei Verfahren darf verwendet werden, wobei die Wahl von der Art des gewebten Flächengebildes abhängt. Für den Schiedsfall wird jedoch Verfahren A empfohlen.

Fo reword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of developing International Standards is carried out through IS0 technical committees. Every member body interested in a subject for which a technical committee has been authorized 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 7211 I2 was developed bY Technical Committee ISO/TC 38, Textiles, and was circulated to the member bod ies in November 1982. It has been approved by the member bodies of the following countries: The member body tech nical gro unds Australia Belgium Brazil Bulgaria Canada China Czechoslovakia Egypt, Arab Rep. of Finland Germany, F.

INTERNATIONAL STANDARD ISO7211/2-1984(E) Textiles - Woven fabrics - Construction - Methods of analysis - Part 2: Determination of number of threads per unit length 1 Scope and field of application This part of IS0 7211 specifies three methods for the deter- mination of the number of threads per centimetre in woven fabrics. Any of the three methods may be used, the choice depending on the character of the fabric. However, in case of dispute method A is recommended. Method A: Dissection of fabric, suitable for all fabrics. This is the most laborious method but has fewer limitations than the others; in particular, it is the only one that is really suitable for the examination of certain folded structures and other complicated weaves. Method B: Counting glass, suitable for woven fabrics with more than 50 threads per centimetre. Method C: Traversing thread counter, suitable for all fabrics. Where the number of threads per centimetre is low, it may be convenient to express the results as the number of threads per decimetre. NOTE - Methods using parallel line gratings and tapered line gratings have been given in the annex for information. These methods have not been considered accurate enough to be used as standard test methods but can be used to give rough and ready estimates for routine testing. 2 Reference IS0 139, Text/i/es - Standard atmospheres for conditioning and testing. 3 Principle Three methods of determining the number of threads per centimetre are specified, any of which may be used, the choice depending on the character of the fabric. The prin- ciples are as follows: Method A: A section of fabric of dimensions in accor- dance with those given in clause 4 is dissected and the number of threads counted. The threads that are counted are preferably short, 1 or 2 cm being suitabl Method B: The number of threads visible with aperture of a specified counting glass is determined. to be e. n the Method C: The number of threads per centimetre of the fabric is determined with the aid of a traversing thread counter. 4 Minimu
