Ifluence of Yarn Texturing Technological Parameters and Fabric Structure on Tensile Properties of the Polipropylene Fabric
Keywords:air textured yarn, woven fabrics, tensile properties of the fabrics
Tensile properties of the woven fabric are very important properties for upholstered furniture manufacturers. In this study the dependencies of tensile properties of the fabric on yarn air texturing parameters and fabric structure were investigated. It was found, that breaking force and elongation at break depends more on yarn structure, than on air pressure in the texturing jet. The difference of fabric elongation at break does not exceed 2 % and difference of fabric breaking force does not exceed 5 % when yarns of the same structure but produced with different air pressure in the texturing jet were used in weft. In the case when different structure yarn produced with same pressure in the texturing jet were used in weft, there were difference of breaking force and elongation at break up to 25 % stated. There were also investigated tendencies of tensile properties of fabric dependencies on fabric structure itself. It was stated that weave of the fabric influences elongation at break and breaking force of the fabric.
