Abstract

L'invention concerne un tissu sans trame, son procédé de fabrication et ses applications. Le procédé comprend les étapes de déroulement, de regroupement, de division, d'étalement et de collage de fibres à haute résistance. Les fibres à haute résistance collées sont combinées sur au moins un côté de celles-ci avec un film de polyéthylène; au moins deux couches de feuilles à orientation unique sur lesquelles est formé le film sont combinées de manière orthogonale pour produire le tissu sans trame. Lorsqu'il est combiné, au moins un film de polyéthylène est disposé entre deux feuilles à orientation uniques adjacentes. Le procédé de fabrication permet la production du tissu sans trame de grande performance. Le tissu sans trame empêche le problème de stratification et d'augmentation de la dépression lorsqu'il est transformé en un produit pare-balles.
