Abstract:
A method for producing a structured textile material that is made of at least two different base nonwoven fabrics, each having a characteristic color, comprising the steps of:providing at least a first base nonwoven fabric and a second base nonwoven fabric that differs from the first nonwoven fabric, both the first and second nonwoven fabrics containing thermoplastic binding fibers capable of binding fibers of the nonwoven fabrics when activated;inserting an intermediate layer of material capable of adhesive connection to the first and second nonwoven fabrics and laminating the first base nonwoven fabric, the intermediate layer, and the second base nonwoven fabric to form a laminate, without activating the thermoplastic fibers contained therein;needling at least one side of the laminate to create a structured pattern thereon, the needling being performed by one of a fork needle including a fork and a crown needle including a crown, the one of the fork and the crown being completely filled with fibers of one of the base nonwoven fabric before the fork passes through another one of the base nonwoven fabrics; andactivating the intermediate layer and the thermoplastic fibers of the base nonwoven fabrics,wherein the resulting textile exhibits the starting color of one of the fabrics, unmixed with the starting color of the other of the fabrics in the pattern, background and reverse side of the laminate.
