摘要

Despite the development of artificial neural network and computer simulation models that predict yarn tensile properties, the mathematical model is still very important being the base for all models. In this research, three mathematical models have been applied for evaluation of coefficient of fiber strength utilization in staple spun yarns before break at same value of yarn strains. The experiments were conducted on cotton, viscose and polyester fibers, and yarns. The results indicated that our model exhibited least prediction error followed by Pan's and Frydrych's models for cotton and viscose but for polyester, Pan's model produced least error followed by Frydrych's model and our model. The superiority of our model might be resulted from the introduction of the phenomena of fiber directional distribution in the staple spun yarns.
