    Fabric topgraphy influence on nanofibers deposition
    (Wydawnictwo Politechniki Łódzkiej, 2022) Ljungerg, Ida; Sánchez-Martínez, Ainhoa; Martínez-González, Inés; Mínguez-García, David; Montava, Ignacio; Díaz-García, Pablo
    Interest in nanotechnology has increased in recent years and the textile sector has not been left out of this technology. Obtaining nanofibers opens up multiple applications in fields such as filtration. However, due to the fragility of said nanofibers, conventional textiles can serve as a support for the created nanofiber net. In this work we intend to demonstrate the influence of the weave pattern on the homogeneity of nanofibers deposited on the fabric. Two fabrics characterised by wave patterns showing different topography are studied. Authors demonstrate there is a strong influence of topography on the nanofibers deposition. Nanofibers tend to cover wave´s fibres in a higher plane first and it require longer periods to find some fibres on lower planes.

    Fiber cross-section influence on the deposition of nanofibers on textile weaved structures
    (Wydawnictwo Politechniki Łódzkiej, 2022) Mínguez-García, David; Capablanca, Lucía; Montava, Ignacio; Díaz-García, Pablo
    Roughness is directly related to the increase of adhesion between surfaces. Different cross section on fibres implies different longitudinal shape of fibres, altering the roughness of filaments. In this study, a procedure to evaluate the nanofibers adhesion to the substrate has been designed. In order to test it, different cross-section shapes are evaluated to demonstrate its influence on the nanofibers net adhesion. Circular, tetralobal and trilobal fibres were tested. Focused on corroborating it, two yarns with different filament fineness were also tested. Different weights are placed on an acetate film which is placed on the nanofibers net. The pressure helps the nanofiber to move to the acetate. This procedure helps to determine the influence of fibre cross-section or roughness, demonstrating the adhesion of nanofibers net on the structures is enhanced with higher roughness.
