3-Dimension Simulation for Loop Structure of WeftKnitted Fabric Considering Mechanical Properties of Yarn

Abstract

The three-dimension weft- knitted loop model was constructed using the simulated yarn which was made by mass-spring system. The simulated yarn was constructed with the cross-sections consisting of the mass-points connected by the springs within the mass-points. In the simulated yarn, two types of springs were used to describe tensile and bending behaviour of the model. The geometrical knitted loop structure was constructed by setting the cross-sections of the simulated yarn in the loop model considering with the loop parameters. The mechanical properties of the loop model under the tensile condition were expressed by using some formulae considering with the construction of the knitted structure.
