Abstract:

In order to improve the resolution of tufted carpet and enhance its quality, constructing a proper yarn tension model is the key to accurately control the pile height of tufted carpet. This paper firstly introduced the components of a carpet tufting machine and the path of yarns. Then, Euler formula derived from А.П.МИНаКОВ’ is introduced into yarn tension system. Considering yarn bundle as viscoelastic load, sectional modeling for the yarn tension system is undertaken, including models of jacquard roller, constant tension guide yarn roller, and multi-layer yarn guides. Finally, the correctness of the models is verified by comparing the simulated yarn tension curves with those achieved by experimental methods. This research provides a reference for further work in designing yarn tension controllers.
