Embodiment 1

[0025] Example 1 The following steps are adopted to realize the present invention:

[0026] (1) Use a shoveling machine to cut the leather in layers to obtain a surface with a thickness of 0.6mm;

[0027] (2) Cover the cut surface of the dough with a layer of hot melt adhesive TPU film, and use a hot press for the first hot pressing. The pressure of the hot press is 0.3par, the temperature is 120℃, and the first hot pressing time is 15s. After cooling for 5 minutes;

[0028] (3) Use the shape mold to cut the dough after the first heat pressing and cooling to obtain the hollow dough and hollow parts, and cut the distance between the outer contour line and the inner contour line of the figure using the shape mold, that is, the graphic The line thickness is 0.1mm, so that when the obtained hollow part is filled in the corresponding hollow part on the hollow surface, the gap between the figure of the hollow part and the corresponding hollow part is 0.1mm;

[0029] (4) Fill the hollow par...

Embodiment 2

[0030] Embodiment 2 The following steps are adopted to realize the present invention:

[0031] (1) Use a shoveling machine to cut the leather in layers to obtain a dough with a thickness of 0.5mm;

[0032] (2) Cover the cut surface of the dough with a layer of hot melt adhesive TPU film, and use a hot press for the first hot pressing. The pressure of the hot press is 0.2par, the temperature is 110°C, and the first hot pressing time is 10s. After cooling for 3 minutes;

[0033] (3) Use the shape mold to cut the dough after the first hot pressing and cooling to obtain the hollow dough and hollow parts, and cut the distance between the outer contour line and the inner contour line of the figure using the shape mold, that is, the graphic The line thickness is 0.05mm, so that when the obtained hollow part is filled in the corresponding hollow part on the hollow surface, the gap between the figure of the hollow part and the corresponding hollow part is 0.05mm;

[0034] (4) Fill the hollow ...

Embodiment 3

[0035] Embodiment 3 The following steps are adopted to realize the present invention:

[0036] (1) Use a shoveling machine to cut the leather in layers to obtain a dough with a thickness of 0.7mm;

[0037] (2) Cover the cutting surface of the dough with a layer of hot melt adhesive TPU film, and use a hot press for the first hot pressing. The pressure of the hot press is 0.4par, the temperature is 125°C, and the first hot pressing time is 20s. After cooling for 6 minutes;

[0038] (3) Use the shape mold to cut the dough after the first heat pressing and cooling to obtain the hollow dough and hollow parts, and cut the distance between the outer contour line and the inner contour line of the figure using the shape mold, that is, the graphic The line thickness is 0.2mm, so that when the obtained hollow part is filled in the corresponding hollow part on the hollow surface, the gap between the figure of the hollow part and the corresponding hollow part is 0.2mm;

[0039] (4) Fill the holl...

Abstract

The invention discloses a seamless splicing production technology of leather. The leather is processed to be with a certain thickness in advance; then a shape mould is used for cutting, and the hollow-face leather with hollow patterns and hollow parts corresponding to the hollowing positions are obtained; and pressurizing and forming are conducted under a certain temperature, pressure and time by combining a hot press. The defect that according to an original leather splicing production technology, a splicing layer is liable to peel off and crack, is not attractive, not durable and the like is relieved. Tight and seamless attaching of splicing pieces can be achieved, obtained splicing patterns are high in stereoscopic impression and attractive in appearance, portions of the splicing patterns are more attractive and durable, a product is high in stereoscopic impression, and the decoration effect is good. The whole production technology process is simple in step, short in operation time, high in efficiency, safe and environmentally friendly.

Description

Technical field [0001] The invention relates to a leather production process, in particular to a seamless splicing production process of leather, and belongs to the technical field of leather and leather product processing. Background technique [0002] Luggage products have become the necessities of people’s lives. In various occasions such as work, business, and travel, all kinds of luggage have gradually developed from a single function to a diversified and individualized development. People are concerned about the decorativeness of luggage. , Uniqueness requirements are getting higher and higher. [0003] The existing decoration methods on the leather surface of luggage mostly adopt the following two methods. One way is to print or spray directly on the leather surface to form patterns or patterns on the surface of the leather. For example, CN103132347A discloses a method of dyeing and printing on the surface of artificial leather, by printing, spraying or coating on the dyeab...
