 Full text | Abstract: Part II of this article is a continuation of the one presented in Fibres & Textiles in Eastern Europe, No. 1/2008. Part I outlined the innovation of a method of linking yarns by pneumatic interlacing in relation to filament – staple yarns, as well as only staple yarns. The method, the techniques, and the equipment used, as well as the factors selected for estimation of the linked yarns were presented in Part I together with an analysis of the influence of the parameters on the tensile strength properties. In Part II linked yarn parameters, such as hairiness, the unevenness of linear density, the number of faults, and interlacing cohesiveness were analysed. The investigation indicated the dependence of all the process parameters tested, such as the speed and pressure of the air, the construction design of the entangling nozzles, and the properties of the component yarns used, on the linked yarn properties. The initial research carried out indicated the chance of using the highly-efficient technique of pneumatic interlacing as a new means of linking filament and staple yarns, and confirmed the need of further research in this field. |
