Yarn quality is largely influenced by raw cotton materials andspinning technology, dependent on demand quality cotton yarn can be produced by some spinningtechnologies, 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 CompanyLimited and Hoang Thi Loan Company. Tensile strength and break elongation are determined by ISO 2062:2009standard on TENSILON instrument. The results indicate that the higher yarn’s count density is, the smaller itstensile strength is. Tensile strength of 3 types produced by Eight March Textile Company Limited is much morehigher than that of 3 types produced by Hoang Thi Loan company. Yarn break elongation slightly reduces incaseyarn’s count density increases. Break elongation of 3 types produced by Eight March Textile Company Limited ismore higher than that of 3 types produced by Hoang Thi Loan company.
