19、or determining the linear density of yarn from a fabric differs from that of yarn from a package in that, in the former instance, the crimp imposed upon the yarn by the interlacing of warp and weft must be taken into account. Also, the long lengths of yarn used in tests from a package may not conven
20、iently be taken from a fabric. The results obtained may be subject to appreciable personal error unless a standard method is adopted and adequate samples are taken. This part of ISO 7211 is divided into four sections. Sections 1 and 4 deal with items applicable to both methods; section 2 specifies t
21、he method for determination of the linear density of yarn removed from fabric, without removal of non-fibrous matter; and section 3 specifies the method for determination of linear density of yarn removed from fabric after removal of non-fibrous matter. It may be noted that the linear density of yar
22、n obtained by these methods may not be same as that of the original yarn used in the fabric. Section 1. General 1 Scope and field of application This part of ISO 7211 specifies methods for the determination of linear density of yarn removed from fabric. It relates to yarns of nominally uniform linea
23、r density; it describes the method of removing threads from fabric, and specifies the number of threads whose straightened length is to be determined and the methods of determining the mass of all the threads. 2 References ISO 139, Textiles Standards atmospheres for conditioning and testing.
