Abstract
A nonwoven carrier material including at least a first part and a second part whereby the first and the second part including at least two layers of thermoplastic fibers. The first part and the second part are connected with each other in a connecting area to form the nonwoven carrier material whiteout thickness and weight variations in the connecting area. Further, a method for connecting a first and a second part of a nonwoven carrier material to form a connected nonwoven carrier material.
Claims19
A nonwoven carrier material, comprising at least a first part having a thickness and a second part having a thickness,
- wherein the first part and the second part each comprise at least a first and a second thermoplastic fiber layer that are each comprised of fibers,
- wherein the fibers in the first and the second thermoplastic fiber layers of the first part and/or the second part are filaments,
- wherein the first part and the second part are connected with each other via a connecting area to form the nonwoven carrier material,
- wherein the first part and the second part form together a form-fit connection in the connecting area,
- wherein the nonwoven carrier material is obtained by a method comprising removing part of the thickness of the first part and part of the thickness of second part to form the first thermoplastic fiber layer and the second thermoplastic fiber layer in such a way that the first part and the second part together form the form-fit connection in the connecting area, and
- wherein the nonwoven carrier material is free of impregnant prior to forming the form-fit connection in the connecting area.
