Purpose: In order to describe the rheological properties of textile products there have been used various models but none of them delivers the complementary solution for textiles subjected to different fields of loads. Therefore the idea presented by Hasley in 1945 was an inspiration for us to propose the new rheological model based on theory of plastic-elastic solids. Design/methodology/approach: It was assumed that the modified rheological model would consist of two parallel parts: I - Hooke’s spring with rigidity C1 and II - Hooke’s spring with rigidity C2, connected in series with a frictional element with a constant resistance, T and additional force Kε22, and a piston with a weight m displacing in a liquid with a viscosity η, where ε22 is a shift of the piston from its initial position. Findings: The proposed model represents adequately stress – strain relationships of polypropylene monofilaments subjected to tensile test. The results indicate that for each investigated type of nonwovens there is no significant difference between the shape of the theoretical and experimental elastic recovery curve during the recovery test. Research limitations/implications: The application of presented model was used for illustration of the description of relaxation of polypropylene monofilament subjected to tensile load and rheological properties of non-woven fabrics made also from polypropylene fibres subjected to the compression loads. Originality/value: The new rheological model was proposed. It can be universal for description of mechanical behaviour of textiles subjected to the tension or compression loads.
