Pozycja 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, PabloInterest 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.Pozycja Estimating biodegradation of cotton fabric by soil burial(Wydawnictwo Politechniki Łódzkiej, 2022) Sánchez-Martínez, Ainhoa; Belda-Anaya, Raquel; Capablanca, Lucía; Payá, Jaime Gisbert; Bonet-Aracil, MarilésToday we can see a greater awareness of sustainability and environmental protection, however, there are many environmental impacts that are not measured and therefore taking measures to minimize them is not easy. In this article we intend to evaluate the biodegradability of a cotton fabric through the generation of one of the greenhouse gases, CO2. For this, the cotton fabric is buried in an artificial ecosystem and accelerated aging is carried out. The results show that the biodegradability of cotton fabric is around 70-80% of the biodegradability of cellulose.
