Foreword

The revision of this Standard uses ISO 7211-5:1984 "Textiles - Woven fabrics -

Construction - Methods of analysis - Part 5: Determination of linear density of

yarn removed from fabric".

This Standard was redrafted based on ISO 7211-5:1984. The main differences

between this Standard and ISO 7211-5:1984 are as follows:

1 Deleted the introduction;

2 Replaced the international standards by corresponding national standards

or industry standards in normative references;

3 Added inapplicable content in the scope and used partial content of

introduction as notes;

4 Simplified the description of sample quantity; deleted the requirements for

containing different weft tubes; the warp and weft samples were unified

into 2 blocks; weft group weighing was changed to weigh together;

5 Added the calculation of drying value plus official moisture regain;

6 Added the relevant sub-clauses for determination of strand line density

and its representation method (7.3 and 8.3);

7 Added "Sample description" in test report.

This Standard replaces FZ/T 01093-1999 "Textiles - Woven fabrics -

Construction - Methods of analysis - Determination of linear density of yarn

removed from fabric".

Compared with FZ/T 01093-1999, the main technical modifications in this

Standard are as follows:

1 modified 1.3 of the scope in FZ/T 01093-1999 as the content of note;

2 simplified regulation of standard atmospheres for humidity conditioning

and testing;

3 deleted the requirement that the sample preferably contains 5 weft tubes

in the sample request; the warp and weft samples are unified into 2 blocks;

weft group weighing is changed to weighing together;

4 added the calculation of drying value plus official moisture regain.

analysis - Determination of linear density of yarn

removed from fabric

1 Scope

This Standard specifies two methods for determining linear density of yarn

removed from fabric. One method is to determine the linear density of yarn

removed from fabric without removing the non-fibrous material. The other

method is to determine the linear density of yarn removed from fabric after

removal of non-fibrous materials. Choose one of them as needed.

This Standard applies to the determination of the linear density of yarn removed

from most woven fabrics. It is not applicable to the fabrics that the curl on the

yarn cannot be eliminated under a certain straightening tension, and the yarn

is damaged during weaving, finishing and analysis of the method.

NOTE: The linear density of the yarn in the fabric obtained by the method of this Standard may be different

from the linear density of the original yarn before weaving. If the sample is not large enough, the results

may vary significantly.
