Spatial structure`s analysis of 3D knitted spacer fabric

Abstract

The subject of this paper concerns an identification of a spatial structure of a warp-knitted spacer fabric, paying particular attention to the structure of the inner layer. The transverse elasticity of the knitted fabric, both in static and dynamic terms, will depend on the properties of the monofilament, its shape and Young's modulus. The environments of OptaView and Inventor programs were used in the research. Analytical activities were selected that enabled the creation of theoretical models. The empirical verification showed the compliance of the model objects with the actual shape of the threads. It has been proved that the developed methodology can be used in the description of the spatial structure of the spacer knitted fabric as an indispensable element in the numerical experiment of the mechanical properties of the knitted fabric.
