Abstract
The effect of the tension of chemical fibres (monofilaments, complex, reinforced) on their behavior in twisting was investigated. The use of a nylon 6 core instead of Lavsan in combination yarn decreases the stiffness of the yarn in twisting and the generated moment in additional twisting and also decreases the critical moment and increases the critical twisting value, favoring snarl formation. The practical applicability of the Greenhill and Ross criteria for estimating the critical parameters of formation of snarls in twisting fibres of different structure with low tension (fibre slackness). The best agreement of the experimental data with the calculated results was observed for nylon monofilament.
