Abstract

PRODUCCION DE PIELES DE COLORES EXTREMADAMENTE SOLIDOS, NO INFLAMABLES, IMPERMEABLES, LAVABLES Y SECABLES A MAQUINA A PARTIR DE CUEROS AZULES HUMEDOS, MEDIANTE UN PROCEDIMIENTO QUE TIENE LA VENTAJA DE GENERAR VOLUMENES DE RESIDUOS TOXICOS SUSTANCIALMENTE REDUCIDOS. LOS CUEROS AZULES HUMEDOS, SE LAVAN Y TRATAN PARA UNIFORMIZAR EL PH EN SU SUPERFICIE Y EN SU INTERIOR, Y PRODUCIR AL MENOS UNA DE LAS CARACTERISTICAS FINALES DE LA PIEL, COMO LA FLEXIBILIDAD. ESTA FASE ESTA SEGUIDA POR LA INTRODUCCION DE ADITIVOS EN LOS POROS DEL CUERO, QUE ORIGINAN CARACTERISTICAS ADICIONALES, Y LA SUSTITUCION POR UNO O MAS AGENTES SUAVIZANTES, DE LAS GRASAS ORIGINALMENTE PRESENTES EN DICHOS POROS. A CONTINUACION, EN UNA APLICACION TIPICA DE LA INVENCION, SE TIÑE Y SE FIJAN LAS SUSTANCIAS PREVIAMENTE INTRODUCIDAS EN LOS POROS. ESTA FASE VA SEGUIDA POR INMERSION EN UN AGENTE IMPERMEABILIZANTE HIDROFOBO, Y TAMPONADO PARA UNIFORMIZACION E INCREMENTO DEL PH. UN TRATAMIENTO ULTERIOR CONFIERE A LAS PIELES ASI OBTENIDAS A PARTIR DE LOS CUEROS BRUTOS, UN TACTO SEDOSO Y AGRADABLE, AL TIEMPO QUE EL TRATAMIENTO CON SILICONA HIDROFOBA PROPORCIONA IMPERMEABILIZACION Y LAVABILIDAD. ESTA FASE ESTA SEGUIDA POR UNA SEGUNDA ETAPA DE FIJACION.
