Abstract

Se describe un tratamiento para textiles, economico, libre de contaminacion, que se aplica en una celda (30) electroquímica de bajo voltaje, que merceriza (o desengrasa), acidula y opcionalmente blanquea con efluentes y sin la compra de ácidos neutralizantes o blanqueadores a granel, cáusticos. La celda (30) produce base en la cámara (38) catodica para la mercerizacion y una cantidad equivalente de ácido en la cámara (36) anodica para neutralizar la tela. Se utilizan electrodos (32, 34) de difusion de gas para uno o ambos electrodos y pueden generar simultáneamente peroxido de hidrogeno para el blanqueo. La configuracion preferida es una pila de electrodos bipolares, en la cual uno o ambos del ánodo (32) y cátodo (34) son electrodos de difusion de gas y en donde no se desprende gas de hidrogeno en el cátodo (34).
