Structure of Spun Yarn and Its Mechanical Non-Linear Property in the Initial Region of Tensile Deformation

This article analyzes the mechanical non-linear property of spun yarn in initial tensile deformation which has an important bearing on the handle of fabrics.The article describes observations and a statistical analysis of spun yarn structures in different stages of tensile deformation.This statistical analysis mathematically expresses spun yarn structure and makes it possible to present an idealized mechanical structure model.
