The aim of the study is to develop a methodology for the objective determination of tissue hairiness indicator. The study used analytical and experimental research methods. The weight method for studying the hairiness of tissues was substantiated by the analytical method. As an experimental research method, the weighing method for determining tissue hair indices using the ToupView computer program was used. The research results showed that the assessment of tissue hairiness is a prerequisite for the development of optimal technological modes of production and prediction of the surface properties of tissues. The analysis of modern methods for studying the hairiness of tissues has become the criterion for choosing the weight method, the developed algorithm of which includes: obtaining an enlarged image of the surface of the tissue and determining the real diameter of the villi by means of an applied computer program; thermally removed villi from the surface of the fabric; determination of the mass of the removed pile as the difference between the initial mass of tissue samples and the mass of tissue without pile; calculation of a quantitative indicator of tissue hairiness. The obtained quantitative indicator is named the fabric hairiness index and shows the total pile length, which is related to the unit area of the tissue. A weighing method for determining fabric hairiness indicators was developed, and a quantitative indicator, the tissue hairiness index, was first proposed. The proposed method for determining the hairiness of tissues does not require special equipment and can be used in production and laboratory conditions. An objective assessment of tissue by the hairiness index can be used in a comparative analysis of tissues of various nature and degree of hairiness, in the examination of tissues and in the design of fabrics with specified surface properties.
