STUDY OF TENSILE STRENGTH AND BREAK ELONGATION OF COTTON YARNS PRODUCED BY OPEN-END SPINNING

Abstract

Cotton is the natural textile fiber used most popular in the world to produce yarns, threads, apparel, home
furnishings, and other industrial products. Yarn quality is largely influenced by raw cotton materials and
spinning technology, dependent on demand quality cotton yarn can be produced by some spinning
technologies, but most commonly ring spinning and Open-End spinning technology.
The article presents the results of research on tensile strength and break elongation of 3 types of 100%
cotton yarns Ne10/1, Ne16/1 and Ne20/1 produced by open-end spinning at Eight March Textile Company
Limited and Hoang Thi Loan Company. Tensile strength and break elongation are determined by ISO 2062:2009
standard on TENSILON instrument. The results indicate that the higher yarn’s count density is, the smaller its
tensile strength is. Tensile strength of 3 types produced by Eight March Textile Company Limited is much more
higher than that of 3 types produced by Hoang Thi Loan company. Yarn break elongation slightly reduces incase
yarn’s count density increases. Break elongation of 3 types produced by Eight March Textile Company Limited is
more higher than that of 3 types produced by Hoang Thi Loan company.
