Abstract:

The aim of this research was to investigate the mechanical indices of fabrics with fancy yarns before and after fatigue loading and develop a mathematical simulation of the elongation at break of the fabrics investigated. For this purpose fancy yarns were produced in one process using hollow spindles and these yarns were used to weave fabrics. In this research we analyzed and forecasted the breaking force and elongation at break of fabrics with fancy yarns in their structure. It was also noted that the relationships obtained give a possibility to design fabrics with fancy yarns characterised by the best particular properties. It was estimated that fatigue loading significantly influenced the structure of the fancy yarns and consequently changed the mechanical indices of the fabrics containing these yarns. The elongation at break in the weft direction after fatigue increased in almost all fabric variants investigated. Moreover the biggest increase was observed for fabrics containing fancy yarns with waves and a spiral structure, as well as for fabrics containing fancy yarns with a non-periodically located open and closed loop structure.
