Abstract

Procedimiento de hilatura para polímeros viscoelásticos en particular polímeros olefínicos de alto peso molecular, caracterizado por el hecho de que polímeros que, en estado de fusión o en soluciones, solos o mezclados entre sí, se presentan como fluidos viscoelásticos dotados de un componente de elasticidad muy elevado y por consiguiente tienen un flujo o paso diferente del de los fluidos newtonianos, se hilan mediante hileras provistas de agujeros con una relación longitud/ diámetro superior a 1 y de preferencia comprendida entre 1,1 y 30.
