A method of manufacturing a footwear includes the steps of providing a leather base layer and providing a leather attachment layer. The leather base layer and the leather attachment layer are fixed against each other with an intermediate application of adhesive between them. The applied adhesive is activated. The leather base layer and the leather attachment layer are forced against each other under a pressure with the adhesive between them. The adhesive is cured and thereby the leather base layer and the leather attachment layer are bonded to each other. The bonded leather base layer and the leather attachment layer are integrated as part of the footwear.

The invention relates to a method for introducing weaknesses into a decorative material comprising a decorative layer and a carrier layer, preferably used for airbag coverings in motor vehicles, wherein the method comprises the following steps: a) introducing different weaknesses (21) by means of a laser (20) into sections (30) of the decorative material (10) for test purposes, wherein the different weaknesses (21) differ from one another in that the different weaknesses (21) are introduced using different parameters of the laser (20); b) measuring the tear properties of the sections (30); c) determining which section (30) which has a desired tear property and associating the relevant parameters of the laser (20) with this section (30); d) setting the laser (20) at the parameters associated in accordance with e); e) introducing weaknesses (22) into the decorative material (10) by means of the laser (20) set in accordance with step e).

Provided are a biodegradable eco-friendly material and a manufacturing method thereof. The biodegradable eco-friendly material includes a biodegradable base fabric into which paper mulberry yarn and cotton yarn are mixed and woven, a leather layer made of a biodegradable material attached to one side of the base fabric, and a coating layer attached to the other side of the base fabric. Here, the base fabric may be woven in a state where 74 to 76 parts by weight of the cotton yarn and 24 to 26 parts by weight of the paper mulberry yarn are mixed.

A multi-color embroidered leather article includes a leather substrate having a finish surface and a reverse surface and embroidery floss embroidered onto the finish surface. The multi-color leather article is prepared by an embroidery method. The method includes placing the leather substrate on a backing, with the reverse surface in direct contact with the backing; assembling an embroidery hoop on the leather substrate and the backing; embroidering the leather substrate and the backing; removing the embroidery hoop; removing the backing; and clipping excess embroidery floss from the reverse surface.

A multi-layered orthopedic insole has at least four layers. The first layer is leather, the second layer is molded high-density recycled latex foam, the third layer is a molded, rigid density cork-EVA (Ethylene-Vinyl Acetate) footbed, and the fourth or bottom layer is moleskin or moleskin coated to provide a natural grip for gripping a shoe insole. The different layers are fused to form the orthopedic insole of the present invention. The third layer of the multi-layered insole is generally thicker than the other layers and includes sidewalls covered in a leather wrap. The multi-layered orthopedic insole is specifically designed to provide comfort and support to a user's foot using the specified materials, shapes, and contours.

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.

Provided are a biodegradable eco-friendly material and a manufacturing method thereof. The biodegradable eco-friendly material includes a biodegradable base fabric into which paper mulberry yarn and cotton yarn are mixed and woven, a leather layer made of a biodegradable material attached to one side of the base fabric, and a coating layer attached to the other side of the base fabric. Here, the base fabric may be woven in a state where 74 to 76 parts by weight of the cotton yarn and 24 to 26 parts by weight of the paper mulberry yarn are mixed.

Cards made in accordance with the invention include a specially treated thin decorative layer attached to a thick core layer of metal or ceramic material, where the thin decorative layer is designed to provide selected color(s) and/or selected texture(s) to a surface of the metal cards. Decorative layers for use in practicing the invention include: (a) an anodized metal layer; or (b) a layer of material derived from plant or animal matter (e.g., wood, leather); or (c) an assortment of aggregate binder material (e.g., cement, mortar, epoxies) mixed with laser reactive materials (e.g., finely divided carbon); or (d) a ceramic layer; and (e) a layer of crystal fabric material. The cards may be dual interface smart cards which can be read in a contactless manner and/or via contacts.

Process for moulding a composite product (9) for coatings, comprising providing an aesthetic layer (1) comprising an aesthetic material chosen from: natural leather, a first composite material comprising a textile layer and a coating layer comprising polyurethane or polyvinyl chloride or thermoplastics olefins and a second composite material comprising a non-woven fabric comprising polyester or polyamide fibres immersed in a polyurethane matrix, with the polyurethane in weight percentage greater than or equal to 15% and less than or equal to 60% and the polyester or the polyamide in weight percentage greater than or equal to 40% and less than or equal to 85%, providing a support layer (2) comprising a solid polyolefin thermoplastic foam, providing a semi-finished product (3) comprising the aesthetic layer (1) and the support layer (2) coupled together, heating the semi-finished product (3) to bring the support layer (2) to a plastic state, forming the semi-finished product (3) by pressing against each other a first (11) and a second half-mould (12) of a mould (10) with the semi-finished product (3) interposed between the conformation surfaces (13) of the two half-moulds, and with the support layer (2) in the plastic state, cooling the semi-finished product (3) to bring the support layer (2) to a solid state and to realize the composite product (9).

Cards made in accordance with the invention include a specially treated thin decorative layer attached to a thick core layer of metal or ceramic material, where the thin decorative layer is designed to provide selected color(s) and/or selected texture(s) to a surface of the metal cards. Decorative layers for use in practicing the invention include: (a) an anodized metal layer; or (b) a layer of material derived from plant or animal matter (e.g., wood, leather); or (c) an assortment of aggregate binder material (e.g., cement, mortar, epoxies) mixed with laser reactive materials (e.g., finely divided carbon); or (d) a ceramic layer; and (e) a layer of crystal fabric material.
