Investigação estatística do impacto da composição de fios, comprimento da laçada e pontos flutuantes no comportamento da energia de ruptura e tenacidade em tecidos jersey, piquet simples e piquet duplo

Abstract

This research focuses on the statistical analysis of the effects of yarn composition, loop length and float stitches on the strength and tenacity properties of Jersey, single Piquet and double Piquet fabrics. These samples were then subjected to breaking strength tests to measure the energy required for the fabric to rupture and the fabric's ability to resist rupture. The results obtained were statistically analyzed, using the Design-Expert software to identify the relationships between the studied variables. It was possible to observe that the composition of the threads, the length of the loop and the omitted stitches had a significant impact on the behavior of the breaking energy and tenacity of the fabrics. In particular, certain yarn compositions have demonstrated greater tear strength and toughness compared to others. In particular, 100% polyester yarn compositions demonstrated higher tear strength and toughness compared to others. In addition, the loop length had a direct influence on the results regarding tenacity and breaking energy in the Jersey structure, the amount of floating points also influenced these properties in the Single Piquet and Double Piquet structures, showing that changes in these parameters can lead to significant changes on the strength and tenacity characteristics of. These findings have important implications for the textile industry as they provide valuable information on how yarn composition, loop length and float stitches can affect the quality and performance of Jersey, single-Piquet, and double-Piquet fabrics. These insights can help in optimizing the manufacturing process and creating fabrics with specific properties, meeting the demands of application needs, and improving the final engineering properties of the product.
