Isfahan University of Technology Journal of Computational Methods in Engineering 2228-7698 23 1 2022 12 31 Estimation of Open-End Cotton Yarn Strenght from Fiber Physical Characteristics Estimation of Open-End Cotton Yarn Strenght from Fiber Physical Characteristics 203 209 2866 FA S. A. Hosseini G. Afkhami A. Tabibi And A. Sadeghi Journal Article 2022 12 31 Physical properties of cotton yarns are affected by the characteristics of cotton fibers such as fineness, length, maturity and strength. This relationship has been worked out by means of multivariable regression and stepwise method for an open-end spun (NeC 20) cotton yarn. Moreover, with the help of linear programming, it was made possible to determine the percentage of different cottons in the blend with the aim of reducing the yarn price to a minimum while keeping the yarn quality to a certain level.
