Abstract

FIBRAS DE POLIBENZAZOL SE PUEDEN SECAR RAPIDAMENTE SIN DAÑOS INDEBIDOS A LA FIBRA EXPONIENDOLAS A DOS O MAS TEMPERATURAS DE PUNTO DETERMINADO CON LAS TEMPERATURAS QUE ESTAN SELECCIONADAS RELATIVAS AL CONTENIDO DE HUMEDAD RESIDUAL DE LA FIBRA. EL TIEMPO DE ESTANCIA REQUERIDO POR LA FIBRA EN CADA TEMPERATURA PROGRESIVAMENTE MAS ALTA SE PUEDE REDUCIR SI LA FIBRA ESTA SIEMPRE EN CONTACTO PLENO CON LA TEMPERATURA DE PUNTO DETERMINADO DEL EQUIPO DE SECADO.
