C ALCULATIONS In order to predict the yarn quality through digital simulation, it is essential to predict the yarn quality with higher accuracy in the spinning process. In this paper, a further exploration was made to this part and artificial neural network model was built to predict yarn strength and evenness. And also it was verified that the system did the good job for predicting yarn tenacity and evenness CV% exactly with the relative error of less than 4% after the model being trained. The accuracy can meet the demand of spinning factories and so the predicting results would be useful for guiding the spinning practice.
