 Full text | Abstract: In many cases single yarns do not fulfill the requirements necessary for the production of certain types of textiles. At the same time, they do not have most of the characteristics that are important for textile production with outstanding quality parameters. Therefore, the twisting process is employed to produce twisted yarns which can be used to produce fabrics for various applications. The breaking properties of twisted yarn depend on the strength of the component yarns, the number of strands, the twisting amount, the friction forces between the yarns, as well as on the twisting method used. The use of known parameters of twisted yarns determines the relations defining their breaking force. The breaking force is here defined as a function of the breaking forces of the component yarns, the number of yarns twisted in the yarn, and their angle to the twisted yarn axis. In addition, based on experimental results and the theorethical equations, real mathematical relations were established which can serve to project the breaking forces of ring and rotor twisted yarns obtained by the method of double layer twisting. This will simplify and improve the technical preparation of the weaving process. |
