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

Part 1: Observation and Analysis of Structure of Spun Yarn

Abstract

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.
