Annotation: The strength of spinning products formed by the wet finning method is determined by the adhesion forces that arise between the contacting fibers. To predict the strength of yarn and roving obtained in this way, it is necessary to know the number of fiber contacts in the cross section of the product. Studies of the distribution of fibers in the section of linen roving have been carried out and a method for determining the number of fiber contacts has been proposed. The initial data are digitized images of roving sections obtained using a digital microscope. After threshold processing of the image, the perimeters and areas of continuous sections occupied by fiber sections were calculated. The area of a single fiber is defined as the average area of the five smallest sections in the section. Based on the analysis of these data, a mathematical model of the dependence of the number of contacts between fibers on the perimeter of the section of the spinning product was constructed.
