Abstract

Despite the fact that tensile behavior of woven fabrics has been previously explored, the nonisotropic material qualities of fabrics can be considered from various points of view. From this perspective, this study is carried out to comprehensively inspect the tensile behavior of woven fabrics. Since worsted fabrics are considered in outwear clothing and their extension under low loads determines their shaping on the body, the extension behavior of the worsted woven fabrics in various directions was probed thoroughly. It was found that fabric stress variations in terms of time in all directions trace in a parabolic manner but the shape of the curve (open or close form) depends on the fabric direction. The above mentioned phenomenon is related to weft and warp yarn crimps and their contribution to tolerating the tensile load. In all fabric directions, it is possible to identify the tensile behavior index, which is the time of change in the fabric’s tensile behavior. The value of tensile behavior index against fabric direction follows a sinusoidal function, and it is affected by fabric weave structure and density.

Highlights

Fabric’s mechanical properties have an important influence on fabric behavior during the manufacture and final product end uses
Since fabric is a nonisotropic material, it is expected that its extension behavior under tensile loads changes according to the fabric direction
The results revealed that at the 95% confidence interval, the effect of weft density and weave structure is significant on the tensile behavior of woven fabrics

Summary

Introduction

Fabric’s mechanical properties have an important influence on fabric behavior during the manufacture and final product end uses. This behavior is the result of warp and weft yarn’s orientation to the direction of tensile load in each sample.
