The effect of adhesive interlining on the creep behavior of a woven fabric in the bias direction was investigated. Three-element viscoelastic models were used to approximate the creep behavior of a face fabric and adhesive interlining. The creep model of a laminated fabric comprised a six-element model connected in parallel with the three-element model. Creep tests were carried out using face fabrics, adhesive interlinings, and their laminated fabrics without and with bonding adhesive interlining by hanging samples in the 45° bias direction under their own weight for 7 days. Creep strains of face fabrics bonded with adhesive interlining were found to be weaker than those of the face fabrics. The creep behavior for the face and interlining fabrics could be approximated using the three-element viscoelastic model with appropriate parameters. The experimental creep behavior of a laminated fabric without bonding was similar to the experimental behavior. However, the experimental creep of laminated fabrics with bonding interlining was less than the calculated creep owing to the increase in stiffness due to the adhesive. By revising the six-element model with the strains just after hanging and for 2 days, it was possible to predict the creep strain over 7 days.

“…Crossing yarns in the bias direction of fabric are more easily deformed than those in the yarn direction. [1][2][3] Bias-cut fabric is able to give a soft look and drape, and is thus usually used for flared skirts or dresses. Bias-cut fabric is also partly used for circular skirts.…”

“…Buckenham 9 compared the KES-F and bias extension test methods and concluded that the bias extension test is more appropriate for characterizing fabrics in the trellising deformation. Takatera et al 10 carried out the bias extension test using the rod-clamp method and concluded that deformation in a fabric sample tested with the bias extension method cannot correspond to the pure shear state when large loads are applied. Potluri et al 11 proposed a wide strip bias extension test and investigated the meso-scale shear deformation of textile composites.…”

The ability of a textile product to change shape under motion-based diagonal forces defines the shear behavior of a fabric and its suitability for a wearable garment design. The principal aim of this study is to introduce a new shear frame and investigate the effects of raw material and setting on in-plane shear behavior of woven fabrics. For this purpose, the mechanical properties of systematic and commercially available non-systematic fabrics were measured. A novel approach to determine the in-plane shear behavior of woven fabrics via two complementary shear frame measurements was presented. The results were also compared with a conventional method known as the bias extension method. It was established that the proposed method provides more accurate and precise results. In order to investigate the correlation between in-plane shear behavior and other mechanical properties, bending rigidity and extension ability of fabrics were measured as well. The analyses regarding the relations between selected fabric parameters showed that there are considerably high correlation coefficients. The effect of raw material and setting was likewise found out to be statistically significant.

“…done by many other researchers [9][10][11][12][13][14][15][16][17], and a great number of testers have been developed. Although those works opened a new era of understanding the mechanical properties of woven fabrics and designing the fabric tensile testers, it should be noted that because of the complex mechanical properties of woven fabrics, the existing testers which are theoretically capable of making the measurement are still unsuitable to be applied into the practical use or have serious limitations.…”

A new creditable and effective multi-axial circular tensile tester (MACTT) with 16 load sensors installed around a circumference has been developed. The new tester can be used to measure tensile properties in various directions with one sample simultaneously under the same initial conditions. As a result, not only an error can be reduced but also the experiment samples and time can be saved. The experiment results show good agreement with the theoretically approximate values calculated based on the Hooke's Law. We have also compared the stress distributions obtained by the new tester with those tested by the KES (Kawabata's Evaluation System) instrument and the results confirm that the new tester is theoretically reasonable and practically feasible for measuring orthotropic tensile properties of the fabrics with symmetrical structures, and that the new tester can also be used to test and evaluate the anisotropic tensile properties of those fabrics with no orthogonal main axes.
