23—A THEORETICAL ANALYSIS AND EXPERIMENTAL STUDY OF THE PLAIN SQUARE WEAVE: PART II: THE ASSESSMENT OF THE LENGTH OF YERN PER UNIT CELL IN THE WOVEN STRUCTURE

Techniques for obtaining an accurate assessment of the length of yarn in a unit cell of a woven structure are given. The effect of sett, cover factor, and state of relaxation are particularly examined with these techniques. The stress–strain relations of yarns at low loads, comparable with those for woven yarns, are demonstrated.
