Development of fabrics for adsorbing carbon dioxide and other pollutants from indoor air

Abstract

An attempt has been made to develop cotton-treated fabrics to be used as home textile and decorative products inside the
room, which can adsorb carbon dioxide and thus reduce indoor air pollution. Cotton fabric has been treated with bentonite
clay, aerosol fumed silica and zeolite separately, and then evaluated for adsorption of CO2 gas using newly developed
NITRA fabric gas adsorption efficiency testing equipment. It is found that the fabric treated with a 4% concentration of
bentonite clay, 3% concentration of aerosol fumed silica, and 2% concentration of zeolite adsorbs 23.62%, 28.04%, and
21.35% of CO2 respectively in 24 h. Treated samples are also tested for various physical properties like breaking strength,
flexural rigidity, etc.
