Abstract:
1. A method for fabricating multilayer fabrics having a prescribed integration pattern with winding yarns and binder yarns, comprising the steps of: (a) providing a plurality of winding yarn carriers arranged in a multilayer structure along a first direction and configured such that each winding yarn carrier is operably movable with respect to one another along a second direction that is perpendicular to the first direction, wherein each winding yarn carrier has a set of supply yarn packages adapted for supplying the winding yarns to form a winding yarn layer, whereby the supplied winding yarns from the plurality of winding yarn carriers form a plurality of winding yarn layers; (b) forming a plurality of crossover points of the winding yarns by moving at least one winding yarn carrier along the second direction according to the integration pattern; (c) transporting the binder yarns through the plurality of winding yarn layers at predetermined locations along the first direction, and locking the binder yarns in place; (d) pushing the binder yarns toward the fell of the multilayer fabrics; (e) taking up the formed multilayer fabrics; and (f) repeating steps (b)-(e) until the multilayer fabrics are fabricated to have desired dimensions.
