Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a molded product mainly made of cut natural leather waste.

[Conventional technology]

In the past, various proposals have been made regarding molded products containing cut leather scraps as a component, but in all conventional technologies, the scraps are shredded and defibrated before use, which makes it difficult to manufacture molded products. The process for this was essential.

In addition, since the molded products that have been proposed so far are composed of defibrated leather fibers, they can only provide the feel and appearance of imitation leather.

[Problem that the invention attempts to solve]

Unlike conventional molded products, the present invention does not require a defibration process, and the feel and appearance of the molded products are significantly different from conventional molded products of this type. The purpose is to provide molded products.

[Means and actions for solving problems]

Therefore, the structure of the present invention is characterized in that leather chips made of cut scraps of natural leather cut to a suitable area are integrated into a layered structure with the orientation of the chips substantially aligned through a suitable thermoplastic resin. It is a thing,
Since the molded product of the present invention having such a structure has a layered structure with the leather chips aligned in the same direction, the flat side of the leather chips with the same orientation exhibits a mosaic tile shape woven by each leather chip. The thicker side of the leather chip has a laminated paper pattern, so the front side can be selected to suit the intended use.

〔Example〕

Figure 1 is a plan view of an example of the molded product of the present invention, and Figure ² is a front view of the same. While laminating the chips, a suitable thermoplastic resin P is placed in the gap between each chip C as a binding material, and the chips are integrated by hot pressing to form a block shape.

The thermoplastic resin used may have either hard or soft properties after molding, and can be molded into any shape such as a sheet, board, or block. Further, the resin may be colored, but preferably it is transparent and can be molded. This is because the oriented leather chips are visible from the outside. Furthermore, the resin may be heat-fusible in order to enhance the bonding of each chip.

On the other hand, for board-shaped or block-shaped molded products, the molded size may be handled as a unit, but it may be subjected to post-processing such as slicing it with a slitter or cutting it into board-block shapes as appropriate. . Incidentally, during molding, fine pieces of metal glass, stone, wood, rubber, etc. may be added and kneaded to the leather chips.

The molded products of the present invention that are molded in this way are either block-shaped or sheet-shaped, and can be hard or soft, respectively, so they can be used as flooring materials, wall covering materials, etc. made of conventional wood materials, metals, ceramic tiles, etc. It can be used in the same way as furniture materials. In addition, the soft sheet-like material can be used for bags such as shoes and bags in the same way as conventional leather or synthetic resin sheets.

〔effect〕

The molded product of the present invention is molded with the leather chips made from cut scraps of natural leather aligned in almost the same direction, so that the leather chips that are visible from the outside in the surface direction and the thickness direction (or the opposite) of the molded product are molded. The patterns are different, and it is convenient for the user to use it with the side of the pattern facing up according to his/her preference. In addition, since the cutting waste is used as is, the patterns created by the leather chips processed into various textures and colors can be effectively displayed.

In addition, the molded product of the present invention has the advantage that it can be manufactured easily because it uses cut natural leather scraps that are simply shredded to approximately the same size, so there is no defibration process like conventional products. This also means that worn-out shoes, bags, etc. can be shredded and used as composition materials for the molded products of the present invention.
Therefore, it is possible to effectively utilize resources by using cut scraps, and to reuse resources by cutting and using discarded leather products.

The present invention is as described above, and is extremely useful as a molded product made by cutting natural leather cutting waste and using it as a composition material as it is.
