Abstract
A knitted fabric is knitted from at least three sets of thermoplastic polyurethane (TPU) yarns and has a technical face and a technical back opposite to each other. The knitted fabric has a concave-convex pattern region and a flat plane region continuously knitted with the concave-convex pattern region. In the flat plane region, loops in the technical face are disposed corresponding to loops in the technical back in a one-to-one manner. In the concave-convex pattern region, the number of loops in the technical face is less than the number of loops in the technical back, so the concave-convex pattern region is arched toward the technical back with respect to the flat plane region.
