A muffler insert for motor vehicles, in particular for passenger cars and motor trucks, in the form of a shaped material made from glass fiber material, has a wound continuous glass fiber material which includes a textured glass fiber. When producing the muffler insert the glass fiber material is wound around a carrier in order to form a shaped material, and this shaped material is used as a muffler insert, if appropriate after further processing steps.

1. A muffler insert for motor vehicles made from a glass fiber material, the glass fiber material being obtainable in the form of a wound shaped material of the glass fiber material being wound around at least one carrier, wherein the glass fiber material is a continuous material, wherein the glass fiber material comprises a textured glass fiber, wherein the wound shaped material is present in form of a shaped mat or of a molding, and wherein the wound shaped material has no binder. 2. The muffler insert as claimed in claim 1, wherein the glass fiber material comprises a fancy-textured glass fiber. 3. The muffler insert as claimed in claim 1, wherein the wound shaped material is in a form obtainable by the glass fiber material being wound around at least two carriers. 4. The muffler insert as claimed in claim 1, wherein the wound shaped material thus obtained in the form of a wound blank is permanently consolidated in order to form a consolidated shaped material. 5. The muffler insert as claimed in claim 4, wherein consolidation is by means of air swirling, stitching, interlinking, knotting, needling, felting or crocheting. 6. The muffler insert as claimed in claim 1, wherein the shaped material has no additional consolidation of any kind. 7. The muffler insert as claimed in claim 1, wherein the basic yarn of the fancy-textured glass fiber material contains a melt thread or at least one fiber of the glass fiber material. 8. A method for producing a muffler insert for mufflers, the muffler insert comprising a sound-damping, sound-absorbing or insulating shaped material made from glass fiber material wherein the glass fiber material is a continuous glass fiber material, and the glass fiber material is a textured glass fiber material comprising: winding of the glass fiber material around at least one carrier in order to produce a sound-damping, sound-absorbing or insulating shaped material in the form of a wound blank, wherein the wound blank is in a permanent shape in the form of a shaped mat or of a molding and no binder is used in the production of the muffler insert. 9. The method as claimed in claim 8, wherein the glass fiber material has a fancy-textured glass fiber. 10. The method as claimed in claim 8, wherein the continuous glass fiber material is a single-strand continuous filament. 11. The method as claimed in claim 8, wherein the glass fiber material is wound around at least two carriers. 12. The method as claimed in claim 8, further comprising the step of permanent consolidation of the wound blank present on the carriers, in order to form said sound-damping, sound-absorbing or insulating shaped material, said permanent consolidation being performed by means of air swirling, stitching, interlinking, knotting, needling, felting or crocheting. 13. A muffler having a muffler insert as claimed in claim 1. 14. The muffler insert as claimed in claim 1 being configured for passenger cars or motor trucks with internal combustion engines. 15. The muffler insert as claimed in claim 1 wherein the glass fiber material is a continuous filament. 16. The method as claimed in claim 8, wherein the muffler insert is configured for passenger cars or motor trucks with internal combustion engines.
