Abstract
Son ensenados un nuevo metodo de formacion de fibra, y aparato relacionado, en el cual los filamentos extruidos de material de formacion de fibra son dirigidos a traves de una camara de procesamiento que es definida mediante dos paredes paralelas, al menos una de las cuales es susceptible de ser movida en forma instantanea hacia y fuera de la otra pared; de preferencia, ambas paredes pueden moverse en forma instantanea hacia y fuera entre si. Los medios de movimiento son conectados al menos con una pared susceptible de ser movida para proporcionar un movimiento instantaneo. En una modalidad, el medio de movimiento comprende el medio de desviacion para desviar en forma elastica al menos una pared hacia la otra pared. El movimiento de la pared hacia y fuera de la otra pared es suficientemente facil y rapido de modo que la pared se movera fuera de la otra pared en respuesta a aumentos de presion dentro de la camara aunque regresara con rapidez a su posicion original por el medio de desviacion en base a la reanudacion de la presion original dentro de la camara. En otra modalidad, el medio de movimiento comprende el medio de oscilacion, el cual oscila la pared a una rapida velocidad. La invencion tambien proporciona nuevas telas no tejidas, las cuales comprenden una masa colectada de fibras que incluye fibras interrumpidas en forma aleatoria mediante segmentos de fibra aislados, los cuales a su vez estan constituidos de cadenas de polimeros orientados aunque difieren en morfologia de la porcion principal de la fibra.
