Abstract: 1. Elastic inserts consisting of a substrate on the basis of a woven fabric, a knitted fabric or a knitted fabric with weft insertion, with the material of the warp and weft thread being a filament yarn, and having an adhesive layer and having an adhesive layer applied to one side of this substrate, characterized in that the insert is shagged on the side that is not provided with the adhesive. 2. Insert according to claim 1, characterized in that the filament yarn is produced from polyester and/or polyamide. 3. Insert according to claim 1 or 2, characterized in that the filament yarn has a yarn fineness ranging from 15 dtex to 440 dtex. 4. Insert according to one of the claims 1 to 3, characterized in that the filament yarn has a yarn fineness in the range of 30 dtex to 180 dtex. 5. Insert according to one of the claims 1 to 4, characterized in that warp thread and/or weft thread consist of false-twist textured polyester or polyamide filament yarns. 6. Insert according to one of the claims 1 to 5, characterized in that the filament yarns comprise in addition a twist. 7. Insert according to claim 6, characterized in that the twist lies in the range of 20 to 1,000 T/m. 8. Insert according to claim 6 or 7, characterized in that the twist is in the range of 100 to 400 T/m. 9. Method for the production of an elastic insert of a substrate on the basis of a woven fabric, knitted fabric or knitted fabric with weft insertion, with the material of the warp thread and/or weft thread being a filament yarn, and with an adhesive layer applied to one side of the substrate, by: (a) production of a gray woven fabric, a gray knitted fabric optionally with weft insertion of filament yarns, (b) optionally performing a dying step, (c) thermo-stabilization of the gray woven fabric or knitted fabric, (d) coating one side of the obtained gray woven fabric or knitted fabric with an adhesive, characterized in that as a further step a shagging is performed with the surface not provided with adhesive. 10. Method according to claim 9, characterized in that the shagging takes place by emerization. 11. Method in accordance with claim 10, characterized in that for the emerization an emerization paper is used which is wound like a spiral onto at least one emerization roller, with the surface of the insert being shagged by rubbing on this at least one emerization roller. 12. Method according to claim 11, characterized in that the emerization paper has a graining ranging from 40 to 1,000, preferably 100 to 500. 13. Method according to one of the claims 9 to 12, characterized in that the emerization takes place before the coating of the substrate with the adhesive. 14. Method according to one of the claims 9 to 13, characterized in that the emerization takes place during a finishing method before the coating. 15. Method according to one of the claims 9 to 12, characterized in that the emerization takes place after the coating of the substrate with the adhesive. 16. Method according to one of the claims 11 to 15, characterized in that the several emerization rollers are driven independent of each other and rotate independent of each other with or counter the movement of the elastic insert. 17. Method according to one of the claims 1 to 16, characterized in that the at least one emerization roller rotates at a rate of 8 to 20 m/min. 18. Use of an elastic insert according to one of the claims 1 to 8 for reinforcement of pieces of clothing, in particular the front parts of clothing.
