Nanoparticles of Activated Natural Zeolite on Textiles for Protection and Therapy

Activated natural zeolite clinoptilolite is microporous hydrated aluminosilicates crystals with well-defined structures containing AlO4 and SiO4 tetrahedral linked through the common oxygen atoms. It is to point out that zeolites act as strong adsorbents and ion-exchangers but having many other useful properties. Zeolites are nontoxic substance, excellent for UVR and microbes protection, for proteins and small molecules such as glucose adsorption. Due to its cationexchange ability, zeolites have catalytic properties and for that multiple uses in medicine and industry, agriculture, water purification and detergents. The present paper is an attempt to modify cotton and polyester fabrics for summer clothing with addition of natural zeolite nanoparticles for achieving UV and antibacterial protective textiles. For this purpose cotton fabrics were mercerized and polyester fabrics modified by alkaline hydrolysis and by EDA (ethylenediamine) aminolysis. Zeolite in this paper refers to activated particles of clinoptilolite, with some fraction of nanoparticles produced by tribomechanical processing in the patented machine.
