    METODO DE TRATAMIENTO TERMICO CON VAPOR DE AGUA PARA FIBRA DE POLIBENZAZOL.

    . Solicitante/s: THE DOW CHEMICAL COMPANY. Inventor/es:

    ESTA INVENCION SE DIRIGE A LA MEJORA DE LA TECNOLOGIA DE TRATAMIENTO TERMICO PARA LA FABRICACION DE GRANDES CANTIDADES DE FIBRAS DE POLIBENZAZOL. LAS FIBRAS SE TRATAN CON CALOR UTILIZANDO VAPOR COMO EL GAS DE TRATAMIENTO TERMICO EN UN DISPOSITIVO QUE PROPORCIONA UN VAPOR DE FLUJO RAPIDO, CORRIENTE, CONTRACORRIENTE O TANTO CORRIENTE COMO CONTRACORRIENTE.
