The invention discloses a manufacturing method of a sewing-free umbrella. The method comprises the step of connecting an umbrella face onto an umbrella framework for supporting the umbrella face, wherein the specific steps are as follows: (1) providing a fixing part, wherein the longitudinal cross section of the fixing part is roughly in the shape of U, the fixing part is provided with a closed end for being sheathed and clamped on the umbrella framework and an open end for being connected with the umbrella face in a penetrating mode, and a pair of teeth for being connected with the umbrella face in a penetrating mode and then being buckled and locked on the umbrella framework are respectively arranged on the corresponding end surfaces on two sides of the open end of the fixing part, and (2) sheathing and clamping the closed end of the fixing part on the umbrella framework, and using the teeth at the open end to be connected with the umbrella face in a penetrating mode, and then be buckled and locked on the umbrella framework. By utilizing the manufacturing method, the connection between the umbrella face and the umbrella framework does not need to be sutured, only the fixing part needs to be sheathed and clamped on the umbrella framework, then the umbrella face is connected in a penetrating mode and further buckled and locked on the umbrella framework, and the specific operation can be completed through a professional clamp, thereby greatly improving the production efficiency; and the manufactured umbrella is simple in structure, firm and durable, and the umbrella has no seams and is more attractive in appearance. The manufacturing method of the sewing-free umbrella is the reformation and technical regeneration of the traditional structure for connecting the umbrella face with the umbrella framework.
