The present disclosure concerns a module (100) for inline embossing of a leather product (1) comprising a leather support sheet (2) having a surface finish layer of one or more partially cured coating layers. The module comprises an application means (10) to apply a protective foil (4) onto the partially cured layer (3) to form a laminate (5). The module also comprises a pressure group (20) including an embossing roller (21) having an outer surface with a relief structure (22) so as to emboss a negative of the surface relief structure into the leather product, across the protective foil.

A method for producing a multilayer laminar product includes the operations of providing a laminar support, covering a first face of the laminar support with a first covering layer in a polymer resin and consolidating, at least partially, the covering layer. The method further envisages providing, above the first covering layer, a laminar element free of any protective film. The method further envisages pushing an embossed surface against the first covering layer with interposition of the laminar element and causing the polymerization of the first covering layer.

The invention relates to a footwear comprising a footwear upper (FU) attached to a sole (S), the footwear upper comprising - at least one leather base layer (LBL) having a base layer top grain surface and - at least one leather attachment layer (LAL) having atop grain surface and a flesh- side surface, wherein the leather base layer (LBL) is glued to the leather attachment layer (LAL) with the base layer top grain surface facing the flesh-side ofthe leather attachment layer (LAL).

manufacturing recycled leather by using leather. In the present invention, a method for manufacturing leather using a resin and a substrate sheet is technically characterized by comprising the steps of: crushing scraps or waste products generated during the cutting or production of genuine leather to produce crushed leather particles; classifying the crushed leather particles by particle size or component; mixing the crushed leather particles with the resin used in the manufacture of the leather; and dissolving the crushed leather particles in a solvent, followed by filtration for use.

The invention relates to the technical field of simulated cow leather preparation, in particular to a reduced regenerated cow leather material and a manufacturing process, the reduced regenerated cow leather material comprises a cow leather fiber layer, a mixed reinforcing layer connected with the cow leather fiber layer, and a PU film layer connected with the mixed reinforcing layer; wherein the mixed reinforcing layer is formed by intertwining and connecting superfine fibers (or other fibers) and cowhide fibers, and the cowhide fibers in the cowhide fiber layer and the mixed reinforcing layer are cowhide fibers obtained from regenerated cowhide materials. The superfine fibers in the mixed reinforcing layer are superfine fibers obtained from water-soluble figured sea-island fibers through a water decrement splitting method; the production process of the reduced regenerated cow leather material adopts a water decrement splitting method to perform splitting treatment on the water-soluble figured sea-island fiber base cloth. According to the method, green and environment-friendly manufacturing of the reduction type regenerated cowhide material is achieved, and the quality of the reduction type regenerated cowhide material is improved.
