Improvement of silver nanoparticle impregnation on cotton fabrics using a binder

| description | In this work, silver nanoparticles were synthesized by the polyol process, which reduces silver nitrate with ethylene glycol. The temperature effect and the polyvinylpyrrolidone (PVP) amount were studied. The temperatures used were 100, 120 and 140 °C. Three ratios of 0.00, 0.25, and 0.50 (% w/w) of PVP/AgNO3 were established. Nanoparticles with sizes less than 30 nm were obtained in conditions of 120 °C and 0.5 % w/w of PVP/AgNO3. Posteriorly, nanoparticles in concentrations of 10 and 20 ppm were deposited on cotton fabric by the pad-dry-cure technique, in order to analyze their bactericidal properties against the Gram positive bacteria Staphylococcus aureus 25923. The tests showed that cotton fabric with nanoparticles in concentrations of 10 and 20 ppm had good bactericidal properties, reducing bacterial colonies by over 98 %. Finally, a washing stability study of the fabrics impregnated with silver nanoparticles was performed, and an acrylic binder was added during the impregnation process. The results were obtained by bacteriological analyzes. |

Se estudió el efecto de la temperatura y la cantidad de polivinilpirrolidone (PVP). Las temperaturas utilizadas fueron 100, 120 y 140 °C. Se establecieron tres relaciones: de 0.00; 0.25 y 0.50 (% w/w) de PVP/AgNO3. Las nanopartículas con tamaños menores de 30 nm se obtuvieron en condiciones de 120 °C y 0.5 (% w/w) de PVP/AgNO3.Las nanoparticulas obtenidas en concentraciones de 10 y 20 ppm fueron luego depositadas en telas de algodón, mediante la técnica “pad-dry-cure” (tela curada y seca), a fin de analizar sus propiedades contra la bacteria Gram positiva Staphylococcus aureus 25923. Las pruebas mostraron que las telas de algodón con una concentración de 10 y 20 ppm tenían buenas propiedades bactericidas, debido a la reducción de las colonias de bacterias por encima del 98 %. Finalmente, se llevó a cabo un estudio de estabilidad del lavado de las telas impregnadas con las nanopartículas de plata, y, además, se utilizó un ligante acrílico durante el proceso de impregnación. Los resultados se obtuvieron mediante análisis bacteriológicos.
