The Theoretical Behavior of a Tricot Warp Knitted Fabric Subjected to Biaxial Stresses

A mathematical model of a two guide bar tricot warp knitted fabric under biaxial stresses wasdeveloped in this paper and the behavior of this approximation of a real fabric was analyzed. Somefactors such as yarn jamming, fabric geometric relations, fabric stress-strain relations, development ofbiaxial geometry and effect of yarn friction and extensibility were considered.The work follows theearlier work in which the theoretical behavior of a plain weft knitted fabric under biaxial stresses isinvestigated.The results of the theoretical analyses show a good agreement with the previous work andindicate that warp knitted fabric develop a unique mechanical behavior from its geometry and ability todeform by interyarn slipping. This structural behavior combines with the tensile properties of the yarnsto give the final behavior of 'the fabric.
