    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.

    Research on surface geometry of woven fabrics of different structure
    (Wydawnictwo Politechniki Łódzkiej, 2022) Kosiuk, Gabriela; Matusiak, Małgorzata
    The geometric structure of surface of textile materials is of significant functional, operational and aesthetic importance. Generally, the geometric structure of the surface of materials consists of three main elements: shape, waviness and roughness [1,2]. Parameters characterizing a quality of fabrics surface, i.e. surface topography are strongly related to the fabrics’ structure, raw material composition and a way of finishing. The aim of presented work was to analyse the parameters characterizing the geometric structure of the surface of cotton woven fabrics with different weaves. Totally, 12 fabric variants were the objects of the investigations. They were woven fabrics of 6 weaves and 2 kinds of weft yarn. Surface topography measurements were made by means of the MicroSpy® Profile profilometer by FRT the art of metrology™ [3]. Using the Mark III software cooperating with the profilometer, the basic parameters characterizing the geometric structure of the fabrics’ surface were determined according to standard [4]. Results showed that the fabrics differ between each other in the aspect of the majority of parameters characterizing the surface geometry. Statistical analysis confirmed that weave and linear density of weft yarn significantly influence the surface properties of the investigated fabrics.
