Abstract

Procedimento per fabbricare un nastro continuo di velo formato da filamenti polimerici termoplastici. Per la produzione dei filamenti polimerici viene impiegato un filatoio con camera di raffreddamento collegata a valle e con canale di stiramento. Le portate dei flussi polimerici che fuoriescono dal filatoio, le portate dell'aria di raffreddamento e/o dell'aria del processo di stiramento, la velocità' e la temperatura dell'aria di raffreddamento e/o dell'aria del processo di stiramento vengono scelte in modo tale, per cui i singoli filamenti polimerici presentano un ridotto diametro del filamento e un ridotto grado di cristallizzazione. I filamenti polimerici vengono depositati su di un nastro con filtro in modo da formare un nastro continuo di velo del prodotto preliminare. Quest'ultimo viene riscaldato alla temperatura di stiramento e viene stirato entro un campo di stiramento compreso tra il 100% e il 400% sia in direzione longitudinale sia anche in direzione trasversale, ossia in senso biassiale. Successivamente avviene una fissazione termica. Il grado di cristallizzazione viene aumentato nel nastro continuo di velo così ottenuto.
