Effect of Construction on Strain distribution in Woven Fabrics under Uniaxial Tensile Deformation

Woven fabrics form an integral part of technical textiles where strength is of prime importance. Amongst various factors found to affect the tensile properties of woven fabrics, change in weave and numbers of yarns is expected to alter initial crimps, ease of crimp interchange and fabric assistance in both the principle directions of testing. Accordingly, a strain analysis of plain and satinette woven fabric samples in raveled strip testing mode were undertaken in this work. The samples were generated under similar weaving conditions while varying only the pick density systematically. An analysis of the strain pattern reveals many interesting observations, the most significant ones being (1) the direct relation between the percentage yarn strength utilization in fabric with the uniformity of strain levels along the two principal directions and (2) a significant difference in the strain distribution of samples tested along warp and weft directions irrespective of the construction.
