Stitched fabric type self-repairing inner tube

The invention provides a stitched fabric type self-repairing inner tube. A thin fabric with certain elasticity and very high strength is cut into a variety of flaky materials or cylindrical materials capable of being stitched and sewed to be of the shape of the inner tube, a layer of sealant (2) is paved in the fabric (1), and an isolation layer (3) covers the sealant. At the stitching site of the stitched material, no sealant is paved on a strip (4) with certain width on the fabric at one side, a layer of isolating strip (6) is clamped between the fabric at the fabric edge (5) at the other side and the sealant, the fabric edge (5) and the strip (4) are overlapped and stitched and the isolating strip is stripped off, and needle eyes are sealed by a sealing strip (7). Therefore, the self repair of the inner tube is completed.
