Description

Technical Field

[0001] This invention relates to the field of leather and fur product processing technology, specifically to a process for splicing fur materials. Background Technology

[0002] Shearling leather combines the toughness of leather with the texture of fur, making it commonly used in clothing, bags, and other products. Its natural texture and color possess unique artistic value. Currently, the technology for applying shearling leather to decorative painting is relatively scarce. Existing fur-based decorative paintings mostly involve simple cutting and piecing together of the fur, failing to fully utilize the dual characteristics of leather and fur in shearling leather. Furthermore, the production process often relies on manual cutting, resulting in low precision and inefficiency. Misalignment and weak bonding are common problems during piecing together, leading to unattractive finished products with short lifespans, failing to meet market demand for high-quality shearling leather decorative paintings.

[0003] Furthermore, existing patchwork painting techniques mostly use ordinary glue, which suffers from weak adhesion, easy detachment, and the glue may damage the leather material, affecting the texture and environmental friendliness of the finished product. Therefore, there is an urgent need for a production method that can solve the above problems, achieve precise cutting and secure splicing, and fully reflect the artistic value of leather.

[0004] However, the following typical technical problems still exist in the existing splicing process: (1) Unstable splicing structure: Most processes rely solely on adhesive fixation without taking reinforcement measures for the splicing seams. Under changes in temperature and humidity or external forces, the edges are prone to warping, delamination, or even cracking, affecting the integrity and service life of the work. (2) Single visual layers: When splicing, the coordination of the height, direction and texture of the fur is often ignored, resulting in a flat picture, blurred boundaries, and a lack of three-dimensionality and artistic expression. (3) Insufficient process precision: manual cutting makes it difficult to ensure the splicing and matching of complex patterns, especially in multi-piece misaligned color separation design, which is prone to problems such as misalignment, excessive gaps or overlap, reducing the aesthetics of the finished product; (4) Lack of systematic process control: Existing methods rely heavily on experience and have not established standardized processes for key aspects such as gross height control, backing selection, composite fixing methods and frame protection, resulting in large batch-to-batch differences and making it difficult to achieve industrial replication.

[0005] Although some literature mentions the application of fur in the field of decoration, it mostly focuses on the cutting of whole hides or simple collage. There is no complete technical solution on how to systematically improve the structural strength and artistic quality of collages through methods such as staggered color separation, differential trimming of fur height, adhesive bonding and professional framing.

[0006] Therefore, there is an urgent need for a pure physical splicing painting processing technology specifically for fur materials. This technology does not rely on any heat processing or chemical modification, but achieves high-quality fur art products with clear patterns, rich layers, solid structure and long-term preservation through precise cutting, scientific splicing, composite fixing and professional protection. Summary of the Invention

[0007] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0008] In view of the problems existing in the prior art, the inventors have proposed the present invention.

[0009] Therefore, the purpose of this invention is to propose a processing technology for splicing fur materials. Through the systematic design of splicing fixation, fur height adjustment, humidity and shape control, step-by-step temperature control and subsequent processing, this technology solves the problems of fur charring, splicing failure and unclear patterns in the prior art, thereby obtaining a finished product with clear patterns, natural layers, solid structure and good feel.

[0010] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fur splicing process, comprising the following steps: S1. Cut the whole piece of cowhide into pieces; S2. After cutting out multiple pieces of fur material, separate the colors and splice them together in a staggered manner, and then glue and fix the spliced ​​whole onto the backing. S3. After the components are pasted and fixed, clean the surface, and then comb and seal them. S4. Place the processed finished product into a frame to obtain a fur patchwork painting.

[0011] As a preferred embodiment of the fur splicing process described in this invention, in step S1, the cutting and blanking is performed using a CNC vibrating knife cutting machine.

[0012] As a preferred embodiment of the fur material splicing process described in this invention, in step S3, the bonding between the fur material and the backing is done with No. 1 white latex, and the splicing joint is further fixed by stitching or pressing.

[0013] As a preferred embodiment of the fur splicing process described in this invention, the backing material is cowhide, canvas, or polyester fabric with a thickness of 0.4–3.0 mm.

[0014] As a preferred embodiment of the fur splicing process described in this invention, the process further includes adjusting the fur height on the fur surface after step S2 and before step S3, wherein the adjusted fur height is 2 to 15 mm, preferably 3 to 8 mm.

[0015] As a preferred embodiment of the fur splicing process described in this invention, step S3 is followed by combing and vacuuming the spliced ​​surface.

[0016] As a preferred embodiment of the fur splicing process described in this invention, the staggered color splicing refers to arranging and splicing fur sheets of different colors, textures, or fur lengths in an alternating pattern to form a decorative image with a sense of layering.

[0017] As a preferred embodiment of the fur splicing process described in this invention, the frame is made of acid-free cardboard substrate and UV-resistant glass to protect the color and structural stability of the fur.

[0018] This invention describes a fur patchwork product made using a fur patchwork processing technique.

[0019] As a preferred embodiment of the fur splicing process described in this invention, the surface of the product has no carbonization marks or heat damage areas, and the pattern is formed entirely by the natural color of the fur and the splicing configuration.

[0020] The beneficial effects of this invention are as follows: By employing a staggered color-separated splicing process using multiple pieces of fur material, combined with precise cutting, composite fixing, and fur height adjustment techniques, the problems of traditional fur decorative paintings such as monotonous patterns, weak splicing, and poor layering are effectively solved. The composite fixing method, which combines CNC cutting with No. 1 white latex bonding and sewing or pressing, improves splicing accuracy and structural stability. By adjusting the fur height and performing surface combing and dust removal, not only is the visual texture and tactile feel optimized, but also the blurring of patterns caused by messy fur is avoided. The framing uses acid-free cardboard and UV-resistant glass, ensuring the long-term preservation of the product. Detailed Implementation

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the examples in the specification.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "example" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the invention. An embodiment appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment that selectively excludes other embodiments.

[0024] Example 1 This embodiment provides a method for splicing and processing fur materials using a splicing process, specifically including the following steps: Vegetable-tanned rabbit skin strips and cowhide pieces were selected as multiple pieces of fur material and spliced ​​together in a staggered, color-separated manner according to a pre-designed artistic composition. The original rabbit fur was about 20 mm long. To optimize visual layers and edge clarity, a small fur trimmer was used to adjust the fur height in some areas to 6 mm, and a natural gradient was retained in the splicing transition area to enhance the three-dimensionality of the image.

[0025] Use 0.8 mm thick cowhide as a backing and apply No. 1 white glue evenly to its surface. Cut rabbit skin strips and cowhide pieces are then spliced ​​together in a staggered manner according to the design pattern and glued to the backing as a whole. The seams are machine-stitched with a stitch spacing of 4 mm to form a composite fixing structure of bonding and sewing, which effectively prevents displacement or curling during handling or framing.

[0026] The surface is then gently vacuumed and brushed with a soft brush along the direction of the fur to make the fur neat and the color even. Finally, the finished product is placed in a frame with an acid-free cardboard backing and UV-protected glass to complete the fur patchwork painting.

[0027] After 500 bending and friction tests, there were no cracks or delamination at the splicing points; the pattern boundaries were clear and the color transitions were natural; compared with the untrimmed version, the image depth of this embodiment was significantly improved, and the visual contrast was increased by about 30%. Microscopic observation showed that the dermal fibers were intact, with no thermal damage or chemical residue.

[0028] This embodiment verifies that, without any heat treatment or chemical processing, a balance between high artistry and structural durability can be achieved through staggered color splicing, height adjustment (6mm), composite fixing, and professional framing.

[0029] Example 2 This embodiment provides another splicing process suitable for high-density long-haired leather.

[0030] Natural mink fur (original fur length approximately 25 mm) and dyed sheepskin pieces were selected as multiple fur materials. They were then pieced together in a staggered, color-separated manner according to an artistic design, utilizing the differences in color, luster, and fur length between the two materials to create a visual focal point. To enhance the three-dimensional effect, the fur height in the central area of ​​the pattern was adjusted to 3–4 mm, while 8 mm was retained in the surrounding area, forming a controllable difference in fur height.

[0031] A 1.2 mm thick canvas is used as the backing, and No. 1 white glue is used for bonding. The layers are pressed together at room temperature for 90 minutes to ensure full curing. The seams are further reinforced by hand-sealed concealed stitching to achieve a strong and concealed composite fixation.

[0032] After completion, the surface is vacuumed and combed in a directional manner to make the fur smooth and uniform in direction. When framing, acid-free cardboard is used to separate the fur from the glass, and UV-resistant glass is installed to prevent fading caused by long-term exposure to sunlight.

[0033] The finished product exhibits rich texture variations and natural light and shadow effects. The pattern is entirely composed of the natural color of the fur and the spliced ​​structure, without any artificial branding or coating. After accelerated aging test (simulating 3 years of light exposure), the color difference is E1.0, indicating that this pure physical splicing process has excellent color stability and durability.

[0034] This embodiment demonstrates that by using a design that combines height difference with precise staggered splicing, composite fixing, and professional protective framing, highly artistic fur decorative paintings can be achieved without relying on any heat processing.

[0035] Comparative Example 1 This comparative example is used to verify the necessity of the key splicing process elements in this invention.

[0036] Rabbit skin strips and cowhide pieces were simply joined together (without misalignment or color separation), without trimming the fur (the fur was about 20 mm long and messy), and were simply pasted onto a plain cardboard backing with ordinary glue. No sewing or pressing reinforcement was done, and no surface finishing was performed.

[0037] After being placed directly into a regular picture frame, the following observations were made: the seams were clearly visible and the edges were raised; the messy hair covered the boundaries of the pattern, making the overall picture blurry and lacking in depth; after 200 slight bends, the adhesive layer at the seams failed, with more than 50% of the area peeling off; after being left for a long time, the cardboard became damp and deformed, causing the fur to wrinkle and peel off.

[0038] Compared with Examples 1 and 2, this comparison model cannot meet the basic requirements for decoration and structural stability, which fully demonstrates that if the core steps such as staggered color design, pile height adjustment, composite fixing (adhesion + sewing), professional backing and framing are omitted, even if the same raw materials are used, it is impossible to obtain high-quality fur patchwork paintings.

[0039] The above three embodiments collectively demonstrate that the present invention solves the common problems in traditional fur patchwork paintings, such as obvious seams, insufficient layers, unstable structure, and easy aging, through a purely physical splicing process including CNC precision cutting, staggered color separation composition, differential trimming of fur height (2-15 mm, preferably 3-8 mm), composite fixing of adhesive and sewing, and acid-free and UV-resistant framing.

[0040] The process requires no heating, carbonization, or chemical coatings; the patterns are entirely presented naturally by the colors, textures, and splicing patterns of the natural fur, combining eco-friendliness, artistic uniqueness, and long-term preservation value.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
