Hereinafter, a method of manufacturing a natural cork leather according to the present invention will be described in detail with reference to the drawings and examples.
FIG. 1 is a flow chart showing a method of manufacturing a natural cork according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of a natural cork skin produced by a method of manufacturing a natural cork according to an embodiment of the present invention. 3B is a view showing a state in which a cork bark cut sliced in a normalized state is laminated and press-formed. Fig. 3B is a photograph showing a state in which a cork bark, FIG. 4A is a photograph showing a state in which a cork bark which has been smoothed and dried is cut sliced in an unfixed form, FIG. 4B is a photograph showing a state in which a cork bark produced by press molding a sliced cork bark Fig. 5 is a photograph showing a process of manufacturing a cork fabric by slicing a cork cube.
The present invention relates to a method for producing natural cork leather using natural cork, which comprises a cork fabric manufacturing step (S10), a nonwoven laminating step (S20), a sanding step (S30), a PU laminating step (S40) And a resin coating step (S50).
The cork fabric manufacturing step (S10) is a step of manufacturing a cork fabric with a cork bark. Referring to the drawings, the cork fabric manufacturing step (S10) includes a cork bark ripping and drying step (S11), a cork cube manufacturing step (S12), a fabric And a slice manufacturing step (S13).
The cork bark ripening and drying step (S11) is a step of boiling the dried cork bark into steam and drying it.
The natural cork bark is harvested without cutting, and the extracted natural cork bark is dried for 6 months to 1 year. The first dried cork bark is boiled in the steam and then dried again for a second time. As described above, the cork bark, which has been smoothed and dried, is flattened by the boiling process, and the texture becomes dense and the texture softens.
In the step of manufacturing the cork cube (S12), the cork bark obtained through the cork bark ripening and drying step (S11) is sliced, and the cut slice is press-formed to manufacture a cube. The cube thus produced is sliced and cut into cork fabrics. The pattern of the cork fabric is variously formed according to a method of stacking the cut slices in the process of forming the cube.
For example, if a regular pattern of cork fabric is to be obtained, the cork bark that has undergone the cork bark ripening and drying step (S11) is regularly laminated to form a cork cube. More specifically, the cork bark that has undergone the cork bark ripening and drying step (S11) is sliced to have a predetermined width and length, and the cut slices are arranged so as to overlap each other in the longitudinal direction or the transverse direction, The cork cube is produced by press molding. 3A and 3B are photographs showing such a process. FIG. 3A is a photograph showing a state in which the cork bark, which has undergone the cork bark ripening and drying step (S11), has been sliced into a predetermined width and length (width 10 cm x length 15 cm) and standardized. The cork bark sliced in the normalized state as described above is laminated in the transverse direction or the longitudinal direction, and ISAR SC 495/5 adhesive is applied between the laminated slices and pressed to form a cork cube having a size of 950 mm x 650 mm do. At this time, it is preferable that the bonding temperature is 30 DEG C or more and the compression strength is 100 kpa or more. FIG. 3B is a photograph showing a state in which a sliced cork bark in a standardized state is laminated and press-formed.
Next, in order to obtain irregularly shaped cork fabric, the cork bark is irregularly laminated by the cork bark ripening and drying step (S11) to form a cork cube. More specifically, the cork bark that has undergone the cork bark ripening and drying step (S11) is sliced at an irregular level, and the sliced slices are molded into a molding die to produce a cork cube.
FIG. 4A is a photograph showing a state in which a dried cork bark, which has undergone the cork bark ripening and drying step (S11), has been sliced in an unformed manner. The cork bark, which is sliced without slicing, is placed in a 950 mm X longitudinal 650 mm frame with a cork bark and a cork cube is formed with a compression strength of 200 kpa or more. FIG. 4B is a photograph showing a cork cube manufactured by press-molding a cork bark sliced in a non-standardized form into a mold.
The fabric slice manufacturing step (S13) is a step of slicing the slice cue produced in the step (S12) of manufacturing the cork cube to obtain a cork fabric. 5 is a photograph showing a process of manufacturing a cork fabric by slicing a cork cube. The slice fabric is preferably sliced to a thickness of 0.6 to 1.0 mm.
The step S20 of laminating the nonwoven fabric is a step of laminating and bonding the nonwoven fabric sheet to one surface of the cork fabric fabricated in the cork fabric fabricating step S10. That is, the cork fabric (950 mm in length x 650 mm in length, 0.6 to 1.0 mm in thickness) manufactured in the cork fabric manufacturing step (S10) was extruded using a 0.1 mm thermoplastic polyurethane film (TPU film) First laminate over sheet (0.05t). The nonwoven fabric sheet is interposed between the cork fabric and the polyurethane fiber sheet to be laminated in the next step to reinforce the strength of the natural cork leather. The thermoplastic polyurethane film is used as an adhesive film for bonding the cork fabric and the nonwoven fabric sheet.
The sanding step S30 is a step of flatly sanding the other surface of the cork fabric laminating the nonwoven fabric sheet. The laminated cork fabric of the nonwoven sheet is not sliced to a constant thickness due to its elasticity when slicing the cork cube, so that the thickness is not constant. In the present invention, the cork fabric is processed to a predetermined thickness through the sanding process. It is preferable that the total thickness of the cork fabric laminated with the nonwoven fabric sheet by sanding is in the range of 0.35 to 0.45 mm since it can satisfy the quality of natural cork leather such as strength and flexibility of the product.
The PU laminating step S40 is a step of laminating the polyurethane fiber sheet to the outer surface of the nonwoven fabric sheet of the cork fabric laminating the nonwoven fabric sheet in the nonwoven fabric laminating step S30. That is, in the nonwoven fabric laminating step S30, the cork fabric (total thickness 0.35 to 0.45 mm) laminated with the nonwoven fabric sheet was coated with a PU (polyurethane) fiber sheet (thickness 0.7 to 0.9 mm) using TPU film mm) with a 180 ° compression strength at a pressure of 1 m / bar.
The resin coating step S50 is a step in which the resin is coated on the other surface of the cork fabric laminating the polyurethane fiber sheet laminated in the PU laminating step S40. The resin is preferably a polyurethane such as a laminated polyurethane fiber sheet, and the coating is performed by spraying or applying the resin onto the other surface of the cork fabric which is sanded with the resin solution.
The method of manufacturing the natural cork leather described above and shown in the drawings is only one embodiment for carrying out the present invention and should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is defined only by the matters set forth in the following claims, and the embodiments improved and changed without departing from the gist of the present invention are obvious to those having ordinary skill in the art to which the present invention belongs It will be understood that the invention is not limited thereto.
