Deformation of Cotton Weft-Knitted Fabric Subjected to Tensile Loads

ABSTRACT

The main goal of paper presented is to introduce the SolidWorks environment to model the complex structure of knitted fabric. The geometrical model according to Leaf and Glaskin consists of some paths of unequivocal shape. The problem is described using the physical model and the set of mathematical equations. The structure is next discretized by means of finite element net and used to investigate the biaxial tensile elastic properties of cotton plain knitted fabrics. The obtained theoretical results are verified with a good convergence by means of tensile tests of knitted fabrics.

摘要

本文的主要目的是用 SolidWorks 环境对针织物的复杂结构建模。根据 Leaf 和 Glaskin 的几何模型包括一些明确形状的路径。本文使用物理模型和一组数学方程描述问题，然后通过有限元网络对该结构进行离散化，并将其用于研究棉平针织物的双轴拉伸弹性性能。通过针织物的拉伸试验发现了良好收敛性，这就验证了所获得的理论结果。
