Abstract
The invention provides a method for manufacturing shoe material containing leather and cloth and a shoe material made therefrom. The method includes the steps of: a) material preparation; b) leather treatment; c) gluing; d) TPU (thermoplastic polyurethane) placement; and e) hot pressing. This saves time compared to the sewing process. The shoe material includes a cloth, a leather, a first hot-melt adhesive layer selectively provided on said leather or said cloth, and a TPU film having a second hot-melt adhesive layer covered on the leather and the cloth with the second hot-melt adhesive layer in contact with the leather and the cloth. In this way, the problem of excessive adhesive is avoided.
