Se sintetizó nanopartículas de peróxido de zinc (ZnO2) por el método sol-gel y se las caracterizó estructural y morfológicamente. Las nanopartículas sintetizadas fueron suspendidas en un medio acuoso para funcionalizar tejidos textiles de algodón, obteniendo textiles con propiedades antimicrobianas. La funcionalización fue mediante el proceso de impregnación sobre tejido seco, haciendo uso del equipo denominado Foulard de impregnación. Las muestras textiles impregnadas fueron analizadas microbiológicamente frente a cepas de bacterias Pseudomonas aeruginosa (ATCC 10145) y Escherichia coli (ATCC 25922), posterior a estos análisis se realizaron controles de solideces, análisis de sus propiedades físicas y control del color. De los análisis realizados se concluye que los textiles funcionalizados con nanopartículas de ZnO2 poseen propiedades antimicrobianas. Además las propiedades físicas y las solideces del textil no son afectadas luego del proceso de funcionalización.

Zinc peroxide (ZnO2) nanoparticles were synthesized by sol-gel method and characterized structurally and morphologically. The synthesized nanoparticles were suspended in aqueous medium to functionalize cotton textile fabrics, getting textiles with antimicrobial properties. The functionalization was by impregnation process over dry woven, making use of equipment called impregnation Padder. The impregnated textile samples were microbiologically analyzed against Pseudomonas aeruginosa (ATCC 10145) and Escherichia coli (ATCC 25922) strains. Subsequently, fastness control, physical properties studies and color control analysis were performed over the textiles. We concluded that the textiles functionalized with ZnO2 nanoparticles have antimicrobial properties, moreover, physical properties and textile fastness are not affected after the functionalization process.
