Abstract

Un sistema y método para proporcionar una pluralidad de fibras de una hilera; someter las fibras a aire de enfriamiento; atenuar las fibras a través de una unidad de estiramiento cerrada; reducir una velocidad de la pluralidad de fibras en un difusor que se separa de una salida de la unidad de estiramiento cerrada en una dirección de desplazamiento de las fibras, el difusor que tiene paredes laterales divergentes opuestas; y someter las fibras a una carga electrostática aplicada antes de que las fibras entren en el difusor, en donde la carga electrostática se aplica por una o más unidades de carga electrostática.
