Textiles — Woven fabrics - Construction - Methods of analysis — Part 5: Determination of linear density of yarn removed from fabric

Threads are removed from rectangular strips of fabric, the straightened length of a portion of them is determined and their mass is determined either in equilibrium with the standard atmosphere for testing textiles (method A) or oven-dry plus the commercial allowance given in ISO 6741/4 (method B). Linear density is calculated from the mass and the sum of the straightened length.
