Examination of the Load-Elongation Properties of Fabrics, Yarns and Fibres at 20 and 40 C

A previous study by the authors on the effect of low temperatures on coated and uncoated fabrics raised certain points which were left unanswered. This study addresses these points. It was found that the load-elongation curve of the fabric is not necessarily the same as that of a yarn or a filament; differences in the percent elongation at break of a fabric and its yarn depend on the physical properties of the yarn; inconsistent differences in the percent change in the percent elongation at break for warps and wefts of the same fabric as the temperature is decreased is procedure-dependent and it is the fabric, yarn and filament working in concert which give each fabric its unique load-elongation curve.
