Analysis of warp knitted fabric structure. Part V: experimental study on the initial modulus of warp knitted fabrics

In the previous parts of this series, tensile properties of warp knitted fabrics were investigated using energy method. For this purpose, the geometry of fully threaded two-guide bar structures, i.e. tricot, locknit, reverse locknit, satin and sharkskin were modeled by considering the fabric density...

Summary:In the previous parts of this series, tensile properties of warp knitted fabrics were investigated using energy method. For this purpose, the geometry of fully threaded two-guide bar structures, i.e. tricot, locknit, reverse locknit, satin and sharkskin were modeled by considering the fabric density, yarn diameter and the number of front and back bar underlaps. Then, the theoretical models for the initial modulus of aforementioned structures were obtained. In the present study, the initial modulus of actual fabrics has been calculated using presented models in previous parts. Then, a new test method was defined for tensile testing of warp knitted fabric, specifically. Thereafter, the initial modulus of prepared samples has been measured by using tensile tester in order to compare with theoretical values, based on derived test conditions. Reasonable agreements between theoretical and experimental results showed that generated models are capable to predict the initial modulus of fully threaded two-guide bar warp knitted fabrics, adequately.
