Description

Foil leather

The present invention relates to a leather, and more particularly to a coated leather having a layered structure.

The types of leather can be basically divided into natural leather, recycled leather and artificial leather because of different sources. Among them, the raw materials of natural leather are taken from the raw skin of animals and then processed through various leathers, along with the material and leather structure. Different from natural leather, it can be divided into top layer and second layer. Since the top layer has dermis and leather, it has good structural strength and natural special and clear texture, so it belongs to high-grade leather. The second layer of leather is usually combined with a layer of, for example, a polyurethane (PU) film. The layered structure of the leather is generally called a film leather, that is, the conventional film leather basically comprises: A layer of a film base made of a PU material and a layer of leather bonded to the base layer of the film.

In addition to the use of the base layer of the film to increase the structural strength of the leather layer, the conventional film leather also has gas permeability, folding resistance, water resistance and texture similar to natural leather, so it is a low price but good quality. Leather material. Despite this, the tensile strength of the base layer and the leather layer of the conventional film leather is insufficient, so that there is a problem that the tensile strength is insufficient as a whole. On the other hand, the color of the general film leather is relatively monotonous. If a trademark or a pattern is to be placed on the leather, it can only be printed on the surface of the film base layer, but the pattern is printed directly on the surface of the film base layer, not only the trademark or the pattern. It is easy to be worn and peeled off, and the aesthetics of the product cannot be sustained.

It is an object of the present invention to provide a coated leather having better tensile strength and maintaining better and lasting aesthetics.

The main feature of the present invention is that the film leather comprises a film base layer, a leather layer, and a tensile fiber layer bonded between the film base layer and the skin layer.

A secondary feature of the present invention is that the base layer of the film has a see-through surface, and the film leather further comprises a printed layer bonded to the layer of the tensile fiber and facing the see-through surface of the base layer of the film.

The beneficial effect of the invention is that the tensile strength of the coated leather can be improved by using the toughness of the tensile fiber layer, and the printed layer provided on the tensile fiber layer can be maintained by being protected by the base layer of the film. Good and lasting beauty.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 1, 2, and 3, an embodiment of the coated leather 1 of the present invention comprises a film base layer 11, a leather layer 12 having the same area and spaced apart from the film base layer 11, and a film layer 11 and the skin layer. a tensile fiber layer 13 between the material layers 12, a first bonding layer 14 for bonding the film base layer 11 and the tensile fiber layer 13 together, and a bonding of the tensile fiber layer 13 and the leather layer 12 A second bonding layer 15 is bonded together, and a printing layer 16 is printedly bonded to one surface 131 of the tensile fiber layer 13.

The film base layer 11 is made of a plastic material, preferably made of polyurethane (PU). In the embodiment, the film base layer 11 is made of a translucent PU material, preferably. It is a transparent PU material having a see-through surface 111 away from the tensile fiber layer 13, and a bonding surface 112 spaced from the see-through surface 111 and adjacent to the tensile fiber layer 13. In the present embodiment, the first and second adhesive layers 14, 15 are preferably made of a PU-based adhesive, that is, an adhesive similar in nature to the base layer 11 of the film, and the leather layer 12 is taken from natural leather. Jia is a leather that is commonly known as a two-layer leather.

The material of the tensile fiber layer 13 of the present embodiment is not particularly limited, and a fabric having fine perforation and toughness, such as a non-woven fabric, a woven fabric, or the like, is preferably used, and the printing layer 16 is bonded to the tensile fiber. The surface 131 of the layer 13 is on the surface of the film base layer 11. The printed layer 16 can completely cover the surface 131 of the tensile fiber layer 13 as shown in the embodiment, or can be disposed on the surface 131 corresponding to a partial area of the surface 131, or a plurality of intervals, that is, the printed layer 16 It is not necessary to have a complete connection, and the printed layer 16 may be a variety of beautiful patterns or geometric figures, etc., in addition to a logo pattern or a trademarked character having a marking effect.

Referring to Figures 2 and 4, in the present embodiment, the film leather 1 is first formed into a film-like film base layer 11 from a PU material, and the printing layer 16 is provided on the surface 131 of the tensile fiber layer 13. Next, the film base layer 11 is placed in a pressing mold, and the see-through surface 111 of the film base layer 11 is faced downward, and then a PU-based adhesive is applied on the bonding surface 112 of the film base layer 11, and then The tensile fiber layer 13 having the printed layer 16 is placed over the adhesive while the printed layer 16 is oriented toward the film base layer 11. Finally, a layer of PU-based adhesive is further applied to the tensile fiber layer 13, and the leather layer 12 is placed, and then the assembly is heated and pressurized.

In the process of thermocompression bonding, since the tensile fiber layer 13 and the skin layer 12 are densely covered with minute pores, and the properties of the film base layer 11 are similar to those of the PU-based adhesive, and can be combined in thermocompression bonding. The process of infiltrating into the tensile fiber layer 13 and the skin layer 12, so that when the PU-based adhesive is cooled and hardened, not only the first bonding layer 14 and the second bonding layer 15 can be formed. The tensile fiber layer 13, the leather layer 12, and the film base layer 11 can also be firmly bonded.

It can be seen from the above description that the coated leather 1 of the present invention not only has a novel structure, but also the tensile fiber layer 13 interposed between the leather layer 12 and the film base layer 11 can improve the tensile strength of the coated leather 1 . Thereby, the lack of the tensile strength of the conventional coated leather is improved. On the other hand, the present invention forms the film base layer 11 with a light-transmitting material, and the structure of the printed layer 16 is provided by using the tensile fiber layer 13 as a carrier, in addition to enhancing the marking effect and aesthetics of the film-coated leather 1. Since the printed layer 16 is covered by the wear-resistant film base layer 11, the printed layer 16 can be prevented from being worn and dropped. Therefore, in addition to having a better tensile strength, the coated leather 1 of the present invention can also extend the aesthetics, labeling effect and value of the product.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
