CARACTERIZACIÓN FIBRA DE FIQUE PARA CALZADOCarolina Abril
La búsqueda de alternativas que contribuyen a la preservación del medio ambiente es una marcada tendencia global; sin embargo, ha sido un movimiento poco abordado desde la industria de la moda. Este importante sector económico puede realizar un aporte significativo incorporando elementos ecológicos con alto contenido en diseño e investigación, para crear prendas innovadoras y de calidad. Esta es la filosofía que rige a ECOCALZER, una microempresa que elabora calzado y complementos de moda empleando fibra de fique. La empresa considera que es clave explotar sus habilidades en diseño y optimizar el comportamiento de la fibra para sus productos. Se realizó un proyecto de investigación para evaluar las propiedades clave de la fibra de fique para emplearla como materia prima en la elaboración de calzado, lo que la clasifica como una investigación de carácter descriptivo. En este trabajo se caracterizó fibras de fique mediante RAMAN y TGA, encontrando que su composición está basada en polímeros naturales como celulosa y lignina. Posteriormente se evaluaron sus propiedades mecánicas en estado de entrega y luego de envejecimiento en cámara ultravioleta (UV), comparando el comportamiento de las fibras en medio húmedo y en seco. Se encontró que la resistencia a la abrasión del tejido disminuyó con la humedad y la radiación UV. El tejido presentó una buena resistencia a la flexión en presencia de humedad, observando también que la radiación UV solo lo afecta negativamente cuando está seco. La adhesión del tejido fabricado con fibra de fique al cuero no presentó diferencias respecto a otros materiales usados en la industria del calzado. Se encontró que el tejido sin envejecer es más resistente a la tensión en dirección transversal que longitudinal y que posterior al envejecimiento, esta propiedad disminuye en ambas direcciones. En general, la humedad y la radiación UV afectaron las propiedades evaluadas, un comportamiento que debe estudiarse en futuras investigaciones. Se evidenció que es factible para las pequeñas y micro empresas desarrollar innovación mediante la realización de proyectos de investigación aplicada apoyándose en alianzas estratégicas con entidades educativas y de investigación.
The document provides an extended characterization of Nb3Sn-coated Nb cavity cutouts and Nb coating deposited on Cu substrate. For the Nb3Sn coating, it was found that one half cavity performed poorly due to insufficient and varying thickness of the Nb3Sn layer. Sn-deficiency regions were also observed in the cutouts that could impact superconducting performance. For the Nb film on Cu, preliminary issues identified included surface roughness and potential small Nb carbide inclusions, while no heavy element contamination or grain boundary oxides were found. Further investigation is needed to understand the structural properties.
