Efectos de las Tramas Textiles sobre la Resistencia a la Tracción y Confort Textil en Tejidos Estructurados Impresos en 3D

In this article, an experimental investigation was carried out, about the effects of textile wefts on the tensile strength of 3D printed fabrics. Two additive manufacturing technologies were used: i) fused deposition modeling (FDM) and ii) stereolithography (SLA). Three types of textile wefts were designed in a chainmail pattern, which resemble the main characteristics of a conventional textile for clothing. Through computer-aided design (CAD) the textile structures were sketched, which through a .STL format, were transferred to a 3D printing software, and consequently, they were printed. The specimens were subjected to traction tests to analyze the behavior of the linked structures under tensile loads. The results indicate that the elements structured in the chainmail pattern show a statistically significant effect between the design of the textile weft and its tensile strength. Se analizaron también algunas propiedades importantes en textiles, gramaje, TEX y flexibilidad. This study opens an important field of research on the mechanical resistance of textile structures manufactured by 3D printing, oriented for applications in wearables that have a promising future in the fields of medicine, aerospace, sports, fashion, etc.
