Patent

CA 2183748

The invention relates to a spacer fabric, in particular a velour fabric, having a first layer (1) and a second layer (2) and pile threads (4, 5, 6, 7) joining the layers (1, 2) together. To obtain such a spacer fabric in particular as a basis for the production of a building component formed therefrom by resinification, in which despite increase in strength there is the least possible increase in total weight and/or in which there is achieved as simple and effective as possible processing having regard to resinification, the invention proposes that between the layers (1, 2) and joined to or starting from the freely floating pile threads (4, 5, 6, 7), there be provided branches running in weft and/or warp direction, which branches, in so far as they are woven, are accommodated in a cross-over region between two pile threads (4, 5, 6, 7), each of which alternates from layer to layer (additional weft threads), or runs alternately around neighbouring additional weft threads (additional warp threads).

L'invention concerne un tissu à deux couches espacées, en particulier du velours, constitué d'une première (1) et d'une deuxième couches (2) reliées entre elles par des fils de poil (4,5,6,7). Pour fabriquer un velours de ce type destiné, plus particulièrement, à être utilisé pour la production d'un composant obtenu par résinification dudit velours, et afin d'assurer, malgré une augmentation de la densité, un poids total aussi faible que possible et/ou le traitement le plus simple et le plus efficace possible pour ce qui concerne la résinification, on forme, entre les couches (1, 2), des branches s'étendant dans le sens de la trame et de la chaîne et attachées aux fils de poil (4,5,6,7) flottant librement ou partant de ces derniers. Ces branches, si elles sont tissées, sont insérées dans une zone de croisement entre deux fils de poil (4,5,6,7) placés en alternance entre les couches (fils de trame supplémentaires) ou s'étendent, en alternance, autour des fils de trame supplémentaires voisins (fils de trame supplémentaires).
