The simplified technique of mechanical characteristics of tricot, based on structural element extraction, is developed. The given technique differs from earlier known for relative simplicity of a mathematical description and possibility to predict strength parameters of tricot. The results the developed technique and experimental data about strength of tricot defined by a method "press through by a ball" are compared.
