ZUSAMMENHÄNGE ZWISCHEN DEN GARNEIGENSCHAFTEN, DER GEWEBE-DICHTEPARAMETERN UND DER EINSTELLUNGSPARAMETERN DER MASCHINEN

Abstract

The author has compared the parameters describing fabric density and weaveability. These parameters can be calculated from the cover factor, the density index (this takes also the yarn crossings into consideration) and the yarn stress in the weaving process. The analysis has proved that the structural co-efficient refiects the most sensitively the reldations of weaveability, and the author demonstrates in this article the connection of the structural co-efficient with the multiple density index. Practical measurements prove that yarn stress during the weaving process follows the theoretical relationships with the structural co-efficient and the elasticity co-efficient. This latter one expresses the elasticity of the warp threads and the woven fabrie, resp. Also the relation of the structural co-efficient and the machine setting has been analysed. The results of measurements have proved that the machine setting parameters, i.e., the basic load, the pre-closing of the shed and the breaking angle of the basis level form characteristically the relation of the structural co-efficient and the density index.
