Evaluating Shear Rigidity of Woven Fabrics

Abstract

A new shear tester of woven fabrics based on the trellis shear model is described. The tester can be used to carry out shear deformation experiments under quite low tensile stresses. The values of shear rigidity tested on the new tester were compared with those tested on the uniaxial tensile tester and the KES (Kawabata’s Evaluation System) instrument. The results confirm that the tester is more feasible and effective for measuring shear behavior in a natural state. This study establishes a foundation for constructing a universal instrument that can be used to measure shear deformation under any conditions.

Analysis of shear characteristics of woven fabrics and their interaction with fabric integrated structural factors

“…In-plane shear together with bending of woven fabrics crucially determine the fabric drape, which is defined as the ability of the fabric to fit onto a three-dimensional object. 3 The shear behavior of woven fabrics is a mechanical feature that determines the suitability of the fabric as apparel. The drape, handle, and pliability are fabric properties that are affected by fabric shear behavior.…”

Effects of dot-type adhesive and yarn float on shear stiffness of laminated fabric with interlining

“…The difference in numbers of fixed interlacing points and adjacent yarns was due to the different yarn counts and weave densities. For the fabrics, there was an increase in the ratio of the number of fixed points in the vicinity of adhesive mass of 10 g/m 2 . C (percentage of interlacing points that are fixed) as a function of adhesive mass for each fabric is shown in Figure 9.…”

“…Skelton [1] investigated the limit of shear deformation according to geometrical parameters and proposed an equation for approximating the shear stiffness from a fabric's weight and thickness. Kawabata et al [2] proposed general in-plane finite deformation theory including the shear deformation taking into account the interlacing yarn torque. The model was verified experimentally by Niwa et al [3].…”

Finite Element Analysis of Bias Extension Test of Dry Woven

“…In the composite industry, the shearing behaviour of dry woven plays a crucial role in fabric formability when doubly curved surfaces must be covered [1][2][3][4][5][6][7][8][9]. The ability of fabric to shear within a plain enables it to fit three-dimensional surfaces without folds [10][11][12].…”
