Abstract

SE UTILIZAN UNOS ELEMENTOS DE DETECCION EN UN METODO PARA LA FABRICACION CONTINUA DE FILAMENTOS DE CELULOSA HILADA CON DISOLVENTES PARA DETECTAR LA PRESENCIA DE "DESECHOS" O DE CUALQUIER OTRO MATERIAL NO DESEADO EN LOS FILAMENTOS. EN CONSECUENCIA, SE PRESENTA UN METODO PARA LA PRODUCCION DE UNA ESTOPA DE FILAMENTOS CONTINUOS DE CELULOSA HILADA CON DISOLVENTES SEGUN EL CUAL: I) LA CELULOSA SE DISUELVE EN UN DISOLVENTE DE OXIDO DE AMINA PARA OBTENER UNA SOLUCION DE CELULOSA CALIENTE, II) LA SOLUCION DE CELULOSA CALIENTE SE EXTRUYE A TRAVES DE UN CONJUNTO DE MATRIZ PARA FORMAR UNA ESTOPA DE FILAMENTOS CONTINUOS Y III) SE HACE PASAR A LA ESTOPA A TRAVES DE UN BAÑO DE AGUA PARA LIXIVIAR EL OXIDO DE AMINA, EN DONDE LA MEJORA CONSISTE EN: IV) HACER PASAR A LA ESTOPA DE FILAMENTOS CONTINUOS A TRAVES DE UNOS ELEMENTOS DE DETECCION, V) LOS ELEMENTOS DE DETECCION COMPRENDEN UN HAZ QUE SE PROYECTA A TRAVES DE LA ESTOPA Y TIENEN UN ELEMENTO DE RECEPCION EN EL LADO OPUESTO DE LA ESTOPA, EN DONDE EL ELEMENTO DE RECEPCION SE CALIBRA DE MODO QUE GENERE UNA SEÑAL SI EL OBSCURECIMIENTO DEL HAZ POR PARTE DE LA ESTOPA VARIA EN UNA CANTIDAD MAYOR A UNA PREDETERMINADA. TAMBIEN SE PRESENTA UN APARATO QUE INCLUYE LOS ELEMENTOS DE DETECCION.
