Abstract
Disclosed therein is a reinforced leather. The reinforced leather includes: a leather sheet layer made of a leather-like material; a bonded layer positioned on an upper face of the leather sheet layer; a textile layer positioned on an upper face of the bonded layer and made of cotton fabrics; and a coated layer positioned on an upper face of the textile layer. The reinforced leather can remedy the shortcoming that leather-like materials produced from waste resources get torn easily, be used as leather for shoes due to its high tensile strength and shear strength, and provide a beautiful appearance.
Claims
1. A reinforced leather comprising: a leather sheet layer made of leather wastes, scrap leather, or recycled leather materials; a bonding layer of non-fibrous and singular layer, the bonding layer positioned directly on an upper face, a lower face, and only one side surface of the leather sheet layer to thereby surround three surfaces of the leather sheet layer; a textile layer positioned directly on an upper face of the bonding layer, on a lower face of the bonding layer, and on a corresponding one side surface of the bonding layer to thereby surround the bonding layer, the textile layer being made of cotton fabrics, synthetic resin or non-woven fabrics to enhance mechanical strength of the leather sheet layer; and a coating layer positioned directly on an upper face of the textile layer to further enhance mechanical strength of the leather sheet layer while also improving external appearance of the textile layer positioned on the upper face of the bonding layer; wherein the bonding layer is one selected from urethane adhesives, acrylic adhesives, and hot melted adhesives, to provide a bond of the upper face, the low face and the only one side surface of the leather sheet layer with the textile layer; and wherein the coating layer is one selected from a PVC layer and a polyurethane coating layer.
2. The reinforced leather comprising of claim 1, wherein the coating layer is achieved within a range of temperatures from 70 C. to 80 C.
Description
BRIEF DESCRIPTION OF THE DRAWINGS
(1) The above and other objects, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention in conjunction with the accompanying drawings, in which:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
(5) Reference will be now made in detail to the preferred embodiment of the present invention with reference to the attached drawings.
(6)
(7) As shown in
(8) The leather sheet layer 10 is made of a leather-like material, and the leather-like material is a previously developed and well-known technology as described above, and hence, detailed description thereof will be omitted.
(9) The bonded layer 20 is positioned on the upper face of the leather sheet layer 10.
(10) It is preferable that the bonded layer 20 is one selected from urethane adhesives, acrylic adhesives and hot melt adhesives.
(11) The textile layer 30 is positioned on the upper face of the bonded layer 20 and is made of cotton fabrics.
(12) Furthermore, of course, the textile layer 30 may be made of synthetic fiber or non-woven fabrics.
(13) The coated layer 40 is positioned on the upper face of the textile layer 30.
(14) It is preferable that the coated layer 40 is formed by one selected from polyurethane coating (PU coating) and PVC coating.
(15) The reinforced leather 100 according to the first preferred embodiment having the above-mentioned structure is produced as follows.
(16) First, as shown in
(17) It is preferable that the coated layer 40 is formed by one selected from polyurethane coating (PU coating) and PVC coating, and the coating is achieved within a range of temperature from 70 C. to 80 C. The PU coating and PVC coating are widely known coating methods, and hence, detailed description thereof will be omitted.
(18) In the meantime,
(19) Referring to
(20) Moreover,
(21) Referring to
(22) As described above, since the textile layer 30 and the coated layer 40 are formed on the leather sheet layer 10 through the bonded layer, the reinforced leather according to the present invention can remedy the shortcoming that leather-like materials produced from waste resources get torn easily, be used as leather for shoes or material for sofa sheets due to its high tensile strength and shear strength, and provide a beautiful appearance.
(23) While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
