Development and Durability Analysis of the Functionalized Fabric

Abstract

Nowadays, building insulation must be more and more effective to avoid energy loss. This can result in the lack of ventilation which can cause an increase in the concentration of pollutants in the indoor air, such as Volatile Organic Compounds (VOCs) which are harmful to human health. Different approaches have been proposed to reduce this problem such as ventilation, filtration, depolluting plants, etc. The aim of this study consists of developing functionalized textile substrate allowing the VOCs degradation, ideally into H₂O and CO₂, by the photocatalytic effect under visible light. It is necessary to have photocatalytic activity under visible light for indoor applications as the UV light is filtered by window glasses. To achieve this objective, firstly the samples of woven cotton fabrics are functionalized with the dispersion of silver doped/non-doped TiO₂ in Carboxymethyl Cellulose (CMC) and water by padding process. After that, the treatment sustainability of the functionalized fabric is determined.
