Patent

CA 2687825

The invention relates to a textile coating (2) made from a web (3) of fibres including a first area (5) and a second area (7). The first area is a cohesion area were the fibres (4) of the web (3) are integrated into a tight entanglement (5) holding said fibres (4) and located only on a portion of the thickness (3) of the web. The invention also relates to a method for making a textile coating that comprises: a) while applying an alternating electric field to the web (3) having at least one face (8A, 8B) bearing a heat-fusible powdery binder (12), introducing the powdery binder (12) into the web (3) so as to concentrate the binder (12) at the first area (5); c) melting the binder (12) by supplying heat; and d) leaving or making the binder (12) to cure.

Un revêtement textile (2) est fabriqué à partir d'une nappe (3) de fibres comprenant une première région (5) et une deuxième région (7). La première région est une zone de cohésion où les fibres (4) de la nappe (3) s'intègrent dans un enchevêtrement serré (5) retenant ces fibres (4) et qui est situé sur seulement une partie de l'épaisseur (6) de la nappe (3). Un procédé de fabrication du revêtement textile comprend des étapes dans lesquelles : a) en soumettant à un champ électrique alternatif la nappe (3) dont au moins une des faces (8A,8B) porte un liant thermo fusible en poudre (12), on introduit ce liant en poudre (12) dans la nappe (3), de manière à concentrer ledit liant (12) au niveau de la première région (5), puis c) on fait fondre le liant (12) par un apport de chaleur, puis d) on laisse ou on fait durcir le liant (12).
