Predicting of properties of blended yarn with polypropylene fibers

The method of blended yarn properties predicting is developed. Predicting of the properties of the yarn with polypropylene fibers shows that usage of the developed method can significantly reduce the computational errors of yarn breaking. tenacity as compared with the results of the calculation using the formula of professor A. N. Vanchikov. The advantage of the developed method is ability of prediction of the complex blended yarn characteristics.
