Description

Technical Field

[0001] This utility model relates to a decorative item, and more particularly to a decorative item with a silk visual effect. Background Technology

[0002] In the field of decorative materials, silk has long been regarded as a model of high-end decorative materials due to its unique luster, soft feel, and elegant appearance. However, silk has disadvantages such as high price, easy wrinkling, poor abrasion resistance, and difficulty in cleaning and maintenance, which limit its widespread application.

[0003] Existing decorative materials typically include ordinary textiles, paper, and plastic film. While each material has its advantages, none can fully replicate the effect of silk in terms of luster, texture, durability, and functionality. For example, while ordinary textiles offer advantages in feel and breathability, most cannot replicate the unique luster and delicate texture of silk. Paper can simulate various patterns and textures through printing and molding processes, but it still falls short of silk in terms of luster and texture, and is prone to moisture and mold, resulting in a limited lifespan and a rather monotonous texture. Although plastic film possesses a certain luster, this luster is significantly different from that of silk, offering a limited visual effect and failing to achieve the natural, elegant luster and texture of silk. In applications such as picture frames, the limitations of these materials are even more pronounced.

[0004] Therefore, developing a decorative material that can simulate the visual effect of real silk while possessing excellent performance and cost-effectiveness is of great significance for meeting the market demand for high-end decorative materials. This decorative material should visually reproduce the unique luster and texture of real silk, and its production process should be simple, cost-controllable, and environmentally friendly, thus providing a completely new solution for decorating photo frames and mobile phone cases.

[0065] Example:

[0066] Reference Figure 1 The decorative layer 1 is placed inside the picture frame, which includes a front shell 2 and a back shell 3. The front shell 2 is a transparent layer, and the back shell 3 is a transparent layer, a semi-transparent layer, or an opaque layer, preferably an opaque layer. (Light transmittance refers to the ratio of the intensity of light passing through a material to the intensity of incident light, usually expressed as a percentage. The higher the light transmittance, the stronger the material's ability to transmit light. The percentage of light transmittance is usually relative to the light transmittance of air.)

[0067] The front housing 2 and / or the rear housing 3 are made of one or a combination of at least two of the following materials: glass, acrylic sheet, polycarbonate (PC), polymethyl methacrylate (PMMA), polyvinyl butyral (PVB), crystal, transparent ceramic, transparent plastic film, transparent rubber, transparent silicone, graphene, cyclic olefin copolymer (COC), cyclic olefin polymer (COP), phenyl silicone rubber, and ethylene-tetrafluoroethylene copolymer (ETFE). The materials of the front housing 2 and the rear housing 3 may be the same or different. In this embodiment, both the front housing 2 and the rear housing 3 are made of glass.

[0068] The decorative layer 1 described in this embodiment is composed of fibers, with intersecting fibers forming a mesh 25. The fibers are arranged in a three-dimensional manner, forming a three-dimensional intersecting mesh 25. The fiber placement direction includes one or more of the following: horizontal, vertical, and inclined directions. Each fiber includes one or more of the following: horizontal, vertical, and inclined portions. One or more of the horizontal, vertical, and inclined portions of the fiber intersect each other. The mesh 25 includes horizontal, vertical, and inclined meshes. Each mesh 25 is interconnected with another or at least two other meshes 25. Figure 2 As shown, in the same plane, transverse fibers 21, longitudinal fibers 22, and diagonal fibers 23 intersect each other, with intersection points 24 between fibers, and the intersecting fibers form mesh 25.

[0069] In this embodiment, the fibers of the decorative layer are connected by one or more of the following methods: interlacing, sewing, embroidery, chemical bonding, chemical bonding, electrospinning, friction bonding, and thermal bonding, forming connection points. The number of fiber connection points in the decorative layer can be 1%-100%, 20%-100%, 50%-100%, or 70%-100%. The number of connection points refers to the percentage of fiber connection points relative to the total number of fiber intersections.

[0070] In this embodiment, the fibers are distributed in at least two layers. Fibers in the same layer intersect to form a first mesh, and at least some fibers in different layers intersect to form a second mesh. At least some of the first and second meshes are interconnected, forming a three-dimensional, interconnected network structure. Each fiber layer includes a two-dimensional network structure formed by interlacing fibers in the warp and weft directions and / or a two-dimensional network structure with fibers arranged in a bent pattern. Some fibers intersect at least two fiber layers (two fiber layers), and the fiber layers are staggered to form meshes in different directions. The volume of the mesh accounts for X% of the volume of the decorative layer, where 20% ≤ X ≤ 70%, more specifically, 45% ≤ X ≤ 50%.

[0071] In this embodiment, the fibers of the decorative layer 1 include one or a combination of at least two of the following: synthetic fibers, natural fibers, regenerated fibers obtained from processed natural fibers, metal fibers, and alloy fibers. Specifically, the material selected in this embodiment is synthetic fiber. For synthetic fibers, the materials that can be selected include one or a combination of at least two of the following: polyamide, polyimide, polypropylene, polytetrafluoroethylene, polyester, aramid, and polyphenylene sulfide. In this embodiment, polypropylene is selected. Polypropylene is non-toxic and has high chemical stability, and it does not release harmful substances during normal use. Furthermore, polypropylene has a relatively small environmental impact during production and waste disposal, and its recycling process is relatively mature.

[0072] In this embodiment, the cross-sectional shape of the fibers in the decorative layer 1 can be selected from various shapes, including one or more of the following polygons: circular, elliptical, semi-circular, pentagonal, cashew nut-shaped, corrugated, dumbbell-shaped, triangular, quadrilateral, pentagonal, and hexagonal. Specifically, a triangular cross-section is selected. Setting the cross-section of the fibers to triangular allows for better light reflection. When light shines on the fiber surface, the triangular cross-section of the fiber can refract and reflect light like a prism, producing a unique luster. This luster is very similar to that of silk, giving the user the visual effect of silk. The fiber diameter in the decorative layer 1 with the silk visual effect can be selected from 1μm to 5000μm, specifically, the fiber diameter is 10μm to 30μm. The thickness of the decorative layer 1 is 0.1mm to 10mm, specifically, the thickness of the decorative layer is 0.2mm to 0.4mm. The density of the decorative layer 1 is 10-300g / m³. 2 Specifically, the density of the decorative layer is 20-50 g / m³. 2 .

[0073] To further enhance the aesthetics of the decorative layer 1, the decorative layer also includes at least one pattern. The pattern may be formed with the same or different organizational structure as the decorative layer. The pattern may protrude, recess, or be die-cut into the decorative layer to form a pattern that penetrates the entire decorative layer. The pattern may be formed by a mesh arrangement that is denser or looser than other parts, or the pattern of the decorative layer may consist of a single mesh. The pattern can be presented through one or more of the following techniques: weaving, casting, molding, hot-pressing, sealing some mesh openings, and heat transfer. In this embodiment, the pattern is achieved through heat transfer technology. The pattern can be formed during the process of spinning to create a three-dimensional interpenetrating network structure in the decorative layer, or it can be presented by hot pressing after the decorative layer is formed.

[0074] In this embodiment, the fiber surface of the decorative layer 1 is colored, and there may be one or at least two colors. Furthermore, to further enhance the aesthetic appeal of the decoration, the colors are set as gradient colors.

[0075] The decorative layer 1 is fixed by the front shell 2 and the back shell 3 of the frame. Light passes through the front shell 2 or the back shell 3 (in this embodiment, both the front shell 2 and the back shell 3 are made of glass), giving the frame a silk-like visual effect.

[0076] Furthermore, the decorative item with a silk-like visual effect proposed in this utility model can be a mobile phone case or a decorative item, wherein, referring to Figure 3 The decorative layer 1 is placed on the inside of the phone case 5 (i.e., the side of the phone case 5 facing the phone 4), and the phone case 5 is made of transparent rubber. The decorative layer 1 is fixed in place by the interlocking of the phone 4 and the phone case 5, significantly enhancing the phone's appearance and making it look refined and elegant. The phone case 5 and the phone 4 (or the back cover of the phone 4) form a frame, sandwiching the decorative layer 1 between the phone case 5 and the phone 4. Alternatively, the phone case 5 can also be a transparent film, applied to the surface of the phone's back cover, forming an integral structure with the phone 4.

[0077] Alternatively, the phone case 5 can be a frame with a sandwich structure, with the decorative layer 1 located within the sandwich structure, thereby forming the phone case 5 as a separate decorative item with a silk visual effect as described in this application.
