At the same time, sprayed glue loss is reduced, and the peeling force between the PU leather base cloth layer and a 3D mesh and plastic skeleton may be greatly improved, and the amount of glue sprayed on the overall molding is reduced, thus saving on the cost of glue. The problem of avoiding an insufficient peeling force of a coated sample due to the glue permeation of the base cloth fabric during the coating and glue spraying process is solved.
