Abstract

L'invention a trait à des propriétés d'élongation améliorées de fibrilles-film plexifilamentaires filées éclair. La technique permettant d'obtenir ces propriétés améliorées consiste à accroître le rapport longueur-diamètre de l'orifice de filage, et de réduire la proportion de polymère dans la solution de filage.
