ESTABLISHING THE RELATIONSHIP BETWEEN YARN STRENGTH AND PROPERTIES OF INITIAL FIBERS AND TWIST
The article is devoted to the study of the influence of the scale factor on the strength properties of the tested samples of various materials. The proposed method of calculating the cross-section of samples of textile materials made of yarn or chemical threads is based on summing the cross-sectional areas of all fibers in the sample, which are subject to rupture during its stretching. The main point in the proposed calculation method is the correct, as accurate as possible, determination of the proportion of breaking fibers when stretching the sample.
