Disclosed is a noise-absorbent fabric for a vehicle and a method for manufacturing the same. The noise-absorbent fabric for the vehicle includes a mono-layered nonwoven fabric and a binder. The mono-layered nonwoven fabric is formed of a super fiber, such as an aramid fiber, with a fineness of about 1 denier to about 15 deniers and a thickness of about 3 mm to about 20 mm. The binder is located in the same layer as the nonwoven fabric to maintain a three-dimensional shape of the nonwoven fabric.

The noise-absorbent fabric of claim 1, wherein the super fiber is selected from aramid, polybeszoxazole (PBO), polybenzimidazole (PBI), polyimide (PI), and carbon fiber. 3. The noise-absorbent fabric of claim 1, wherein the super fiber is an aramid fiber. 4. The noise-absorbent fabric of claim 1, wherein the nonwoven fabric has a density of about 200 g/m2 to about 1,200 g/m2. 5. The noise-absorbent fabric of claim 1, wherein the thermosetting resin solution comprises an epoxy resin of about 10 wt % to about 60 wt % as of the thermosetting resin, the catalyst of about 1 wt % to about 5 wt %, the flame retardant of about 10 wt % to about 40 wt %, and the residual solvent. 6. The noise-absorbent fabric of claim 5, wherein the epoxy resin is selected from the group consisting of bisphenol A diglycidyl ether, bisphenol F diglycidyl ether, polyoxyproplyene diglycidyl ether, and bisphenol A diglycidyl ether polymer, and combinations thereof. 7. A method for manufacturing a noise-absorbent fabric for a vehicle, comprising: forming a nonwoven fabric by a needle punching process using a super fiber with a fineness of about 1 denier to about 15 deniers and a thickness of about 3 mm to about 20 mm;impregnating the nonwoven fabric in a thermosetting resin solution;drying the impregnated nonwoven fabric; and curing the dried nonwoven fabric at a temperature of at least 200° C.,wherein the thermosetting resin solution comprises a thermosetting resin of about 10 wt % to about 60 wt %, a curing agent of about 2 wt % to about 10 wt %, a catalyst, a flame retardant and a solvent. 8. The method of claim 7, wherein the super fiber is selected from aramid, polybeszoxazole (PBO), polybenzimidazole (PBI), polyimide (PI), and carbon fiber. 9. The method of claim 7, wherein the super fiber is an aramid fiber. 10. The method of claim 7, wherein the nonwoven fabric is formed by continuously performing up-down needling, down-up needling, and up-down needling. 11. The method of claim 7, wherein in the needle punching process, the aramid nonwoven fabric is formed by needle strokes of about 30 time/cm2 to about 350 time/cm2. 12. The method of claim 7, wherein the thermosetting resin solution comprises an epoxy resin of about 10 wt % to about 60 wt % as of the thermosetting resin, the catalyst of about 1 wt % to about 5 wt %, the flame retardant of about 10 wt % to about 40 wt %, and the residual solvent. 13. The method of claim 12, wherein the epoxy resin is selected from the group consisting of bisphenol A diglycidyl ether, bisphenol F diglycidyl ether, polyoxyproplyene diglycidyl ether, and bisphenol A diglycidyl ether polymer, and combinations thereof. 14. A fabric, comprising: a mono-layered nonwoven fabric formed of a super fiber with a fineness of about 1 denier to about 15 deniers and a thickness of about 3 mm to about 20 mm; anda binder located in a same layer as the nonwoven fabric to maintain a three-dimensional shape of the nonwoven fabric,wherein the binder is formed from a thermosetting resin solution comprising an epoxy resin of about 10 wt % to about 60 wt %, a curing agent of about 2 wt % to about 10 wt %, a catalyst of about 1 wt % to about 5 wt %, a flame retardant of about 10 wt % to about 40 wt %, and a residual solvent. 15. The fabric of claim 14 wherein the super fiber is selected from aramid, polybeszoxazole (PBO), polybenzimidazole (PBI), polyimide (PI), and carbon fiber. 16. The fabric of claim 14 wherein the super fiber is an aramid fiber. 17. The fabric of claim 14 wherein the epoxy resin is selected from the group consisting of bisphenol A diglycidyl ether, bisphenol F diglycidyl ether, polyoxyproplyene diglycidyl ether, and bisphenol A diglycidyl ether polymer, and combinations thereof. 18. The fabric of claim 17 wherein the super fiber is selected from aramid, polybeszoxazole (PBO), polybenzimidazole (PBI), polyimide (PI), and carbon fiber. 19.
