Description

Technical Field

[0001] The utility model relates to the technical field of artificial leather, in particular to a PVC artificial leather with extra-deep patterns. Background Art

[0002] Artificial leather is a plastic product that looks and feels like leather and can be used instead of it. It is usually made of fabric as a base, coated with synthetic resin and various plastic additives. Artificial leather mainly includes two types: PVC artificial leather and PU synthetic leather. The currently popular surface pattern forming process for PVC artificial leather is the vacuum pattern forming process. This forming process has the advantages of clear patterns and high efficiency for shallow patterns, but has disadvantages such as uneven pattern edges and concave pattern tops for very deep patterns. This seriously affects the appearance of the product, resulting in low production efficiency and unstable product quality, which is not conducive to mass production. Therefore, in order to avoid the shortcomings of the existing technology, it is necessary to improve the existing technology. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings and deficiencies in the prior art and to provide a special deep-patterned PVC artificial leather with a simple structure and high production efficiency.

[0004] The utility model is realized through the following technical solutions:

[0005] A special deep pattern PVC artificial leather comprises a base fabric layer and a PVC foam layer attached to the upper surface of the base fabric layer. The PVC foam layer is provided with a plurality of pores with a diameter of Φ0.3mm to Φ0.7mm. The upper surface of the PVC foam layer is embossed with a pattern.

[0006] Furthermore, the thickness of the PVC foam layer is 0.5 mm to 1.5 mm.

[0007] Furthermore, the upper surface of the PVC foam layer is embossed with plain texture.

[0008] Furthermore, the thickness ratio of the PVC foam layer to the base fabric layer is 1:4 to 1:2.

[0009] Furthermore, the PVC foam layer is fixedly attached to the base fabric layer by an adhesive, and the adhesive is evenly scraped onto the surface of the base fabric layer by a knife.

[0010] Furthermore, the amount of the adhesive applied on the surface of the base fabric layer is 100 g / m2 to 140 g / m2.

[0011] Compared with the prior art, the utility model provides a plurality of air holes in the PVC foam layer, so that the pattern on the upper surface of the PVC foam layer is conveniently pressed and set. During processing, the PVC foam glue is first calendered and attached to the base cloth, and a foaming machine is used to foam the plain grain to a specified thickness. Then, a needle wheel is used to roll the needle to produce air holes with a diameter of about 0.5 mm on the surface of the artificial leather. Then, the surface of the artificial leather is heated, and the gas inside is discharged from the air holes. Then, a pattern suction machine is used to suck the pattern to make the pattern clear. The pattern edge of the extra-deep pattern is smooth, and the top of the pattern is not concave. The product has a beautiful appearance, high production efficiency, stable product quality, and is conducive to mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] like Figure 1 The utility model shows a PVC artificial leather with a particularly deep pattern, comprising a base fabric layer 1 as a bottom layer and a PVC foam layer 2 attached to the upper surface of the base fabric layer 1. The PVC foam layer 2 is provided with a plurality of pores 3, each having a diameter of 0.3 mm to 0.7 mm. The upper surface of the PVC foam layer 2 is embossed with a pattern. The pores 3 provided in the PVC foam layer 2 facilitate embossing the pattern on the upper surface of the PVC foam layer. During processing, the PVC foam is first calendered and attached to the base fabric. A foaming machine is used to foam the plain grain to a specified thickness. A needle wheel is then used to produce pores with a diameter of approximately 0.5 mm on the surface of the artificial leather. The surface of the artificial leather is then heated to allow the gas inside to be discharged from the pores. A pattern absorbing machine is then used to absorb the pattern, resulting in a clear pattern. The edges of the particularly deep pattern are smooth, and the top of the pattern is not concave. The product has an aesthetically pleasing appearance, high production efficiency, stable product quality, and is conducive to mass production.

[0017] In a specific implementation, the thickness of the PVC foam layer 2 is 0.5 mm to 1.5 mm.

[0018] The upper surface of the PVC foam layer 2 is embossed with plain grain, which makes the structure of the PVC artificial leather more stable and improves the surface texture and aesthetics of the PVC artificial leather.

[0019] In a specific implementation, the thickness ratio of the PVC foam layer 2 to the base fabric layer 1 is 1:4 to 1:2.

[0020] The PVC foam layer 2 is fixedly attached to the base fabric layer 1 by an adhesive, and the adhesive is evenly scraped onto the surface of the base fabric layer 1 by a knife scraping method.

[0021] The amount of adhesive applied on the surface of the base fabric layer 1 is 100 g / m2 to 140 g / m2, so that the adhesion between the PVC foam layer 2 and the base fabric layer 1 is more stable and firm.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
