Abstract

This paper presents theoretical modeling for predicting the optimum twist angle on yarn made by open end rotor spinning machine in textile industry. Fiber movement on yarn can be used for predicting the optimum twist angle which can be used to reduce yarn breaking in spinning process. In this research the twist angle has been found and the result of this research shows the twist angle around 45°; and the theoretical result of the ratio of rotor diameter to fiber length is .

Highlights

In textile industry the study of the fiber movement inside yarn has been researched of many researchers
Trommer [8] has found that the limitation of the ratio of rotor diameter to fiber length is more than 0.7
It has found that the limitation of the ratio of rotor diameter to fiber length is more than 0.7

Summary

Introduction

In textile industry the study of the fiber movement inside yarn has been researched of many researchers. According to Rohlena [1], Lawrence [2] and Hearle [3], fiber movement on yarn will influence the yarn breakage. According to Lawrence [2], the characteristic of spun yarn can be determined by the fiber movement and yarn structure as Figure 1. According to Lawrence [2] and Rohlena [1], the ratio of yarn length to fiber length, K f , will influence the strength. The influence of ratio K f to the properties of yarn such as diameter of yarn, angle twist, strength, hairiness, yarn delivery, and yarn twist will be discussed and derived in this paper looking from the fiber-yarn movement on cylindrical coordinate and using Lagrange methods
