The present disclosure relates to hobby art, and more particularly to diamond painting.
Diamond painting is a form of mosaic art in which small beads, referred to as jewels, diamonds or drills, are attached to a sticky canvas. Typically the canvas is pre-printed with an image divided into a grid of spaces. Each space includes a symbol corresponding to a particular color of drill, and the user places appropriate drills into spaces in order to create the image, similar to the paint-by-numbers concept.
A diamond art canvas includes a substrate that makes up the structural support for the canvas. The substrate can include a flexible textile with one or more layers, including a print layer configured to receive an image printed thereon. An adhesive layer is applied to the substrate atop the print layer so as to hold the drills that are placed thereon. A plastic protective film is disposed over the adhesive. During diamond painting, the user will peel back the protective film in order to access and place drills onto the canvas. After some time, the user may wish to take a break from diamond painting, and will re-place the protective film in order to protect the remaining exposed adhesive.
Upon manufacture, a diamond art canvas typically is rolled up and deposited into a cylindrical tube for storage and shipping. To use the diamond art canvas, a consumer will remove it from the tube, unroll it, and proceed to place drills for diamond painting. Due to the various layers and materials used, the canvas may be liable to wrinkle, curl at the ends, or otherwise tend to not lay flat.
The present specification discloses aspects that improve a diamond art canvas by reducing its tendency to wrinkle and curl. The improved canvas has a backing layer that is flexible enough to allow the diamond art canvas to be rolled and placed in a cylindrical tube for storage and shipping, but also urges the canvas toward a lying-flat disposition, thus resisting curling of the edges of the canvas and resisting wrinkling. The backing layer is a composite of fibers entrained in an adhesive, and is cured in a manner so that when the diamond canvas is laid flat, the fibers are generally straight. The fibers may have their lengths extend generally within a plane or may be randomly placed such as by spraying the bamboo fibers into the adhesive. When the diamond canvas is rolled up and placed in a tube for shipping, the fibers will bend. When the diamond canvas is taken out of tube, the fibers will urge the diamond canvas back to the flat configuration to thereby prevent wrinkles. Put simply, the fibers embedded within the adhesive will urge the backing layer, and thus the entire diamond art canvas, towards a lying-flat disposition. In order to accomplish this the fibers have a tensile strength between about 700-2000 MPa and a Young's modulus between about 15-45 GPa. The fibers for the backing layer can be bamboo fibers configured and treated to have suitable properties.
In some variations the fibers may have a tensile strength between about 900-1800 MPa and a Young's modulus between about 20-40 GPa. In still further variations the fibers can have a tensile strength between about 930-1770 MPa and a Young's modulus between about 15-45 GPa.
In accordance with one embodiment, the present disclosure comprises a diamond art canvas, comprising a substrate having a front side and a back side. The substrate comprises a flexible textile, a print layer defined on a front side of the textile layer, and a backing layer defined on a back side of the textile layer. An image is printed upon the print layer, the image including a plurality of markers with unique printed indicia. An adhesive is applied to the image surface. A plurality of unique diamond drills are attachable to the substrate via the adhesive and attachable in a pattern corresponding to the unique printed indicia. A protective film is disposed atop the adhesive, the protective film configured to be releasably removed from and reengaged with the adhesive. The backing layer comprises a composite comprising a plurality of fibers entrained in an adhesive, each of the plurality of fibers having a length. The backing layer is configured so that an at-rest condition of the fibers in the backing layer is generally planar. The fibers have a tensile strength greater than about 700 MPa and a Young's modulus greater than about 15 GPa.
In some variations the fibers have a tensile strength less than about 2000 MPa and a Young's modulus less than about 45 GPa. In further variations the fibers have a tensile strength greater than about 900 MPa and less than about 1800 MPa and a Young's modulus greater than about 20 GPa and less than about 40 GPa. In further variations the fibers can have a Young's modulus greater than about 25 GPa.
In additional variations the fibers comprise bamboo fibers.
In still further variations the fibers have a tensile strength between about 930-1770 MPa and a Young's modulus of between about 26-35 GPa.
The plurality of fibers can be randomly disposed in the backing layer.
Additional variations can additionally comprise a cylindrical tube having a diameter, wherein the fibers are selected to be flexible enough so that the diamond art canvas can be rolled up and deposited into the tube, and the fibers are selected to be stiff enough so that when the diamond art canvas is removed from the tube and unrolled the backing layer urges the diamond art canvas toward a planar at-rest configuration.
In accordance with another embodiment, the present specification discloses a method of making a diamond art painting kit. The method includes forming a substrate, which comprises applying a back sealing layer to a back side of a textile layer, applying a front scaling layer to a front side of the textile layer, and applying a backing layer behind a back side of the textile layer. The backing layer comprises a composite having a plurality of fibers entrained in an adhesive, each of the plurality of fibers having a length, the fibers having a tensile strength greater than about 700 MPa and a Young's modulus greater than about 15 GPa. The method can further comprise curing the backing layer when the textile layer is lying flat so that an at-rest configuration of the fibers in the backing layer, when cured, is generally planar.
Some variations additionally comprise applying an image to a front surface of the substrate, applying an adhesive layer atop the image, and applying a removable protective film to the adhesive layer.
Further variations additionally comprise rolling the diamond art canvas and placing the rolled diamond art canvas into a cylindrical tube.
In some variations the backing layer is applied prior to the image being applied.
In additional variations, the fibers of the composite layer are bamboo fibers.
The fibers of the composite layer can have a tensile strength between about 900-1800 MPa and a Young's modulus between about 20-40 GPa.
The fibers of the composite layer can have a tensile strength between about 930-1770 MPa and a Young's modulus of between about 26-35 GPa.
The fibers of the composite layer can be bamboo fibers.
In some variations, applying the backing layer comprises applying an adhesive to the back sealing layer and flocking bamboo fibers onto the adhesive.
In further variations, applying the backing layer comprises applying an adhesive to the back sealing layer and applying a textile comprising bamboo fibers onto the adhesive.
The present specification discloses an improved diamond art canvas that is flexible enough to be rolled and placed in a cylindrical tube for storage and shipping, but also tends toward a lying-flat disposition after removal from the tube, resisting curling of the edges of the canvas and resisting wrinkling.
A diamond art canvas 22 includes a substrate 24 having an image surface 26 upon which a layer of adhesive 30 (see
In some variations the fibers may have a tensile strength between about 900-1800 MPa and a Young's modulus between about 20-40 GPa. In still further variations the fibers can have a tensile strength between about 930-1770 MPa and a Young's modulus between about 15-45 GPa.
With initial reference to
The image 28 is divided into a grid 36 defining spaces 38, each of which includes a symbol. A plurality of drills 40 are provided. Drills are an industry term for clear or colored faceted resin bodies that absorb and reflect light similar to diamonds. It is anticipated that one drill 40 will be placed in each space 38. The symbol in each space corresponds to a particular color of drill 40, and the user is to place the corresponding drill 40 in each space 38 so as to create a mosaic matching the printed image 28. The drills 40 typically are resin beads having a flat side for placement on the image surface 26, and a plurality of facets adapted to produce a shimmering, reflective effect. Drills 40 are also sometimes called diamonds, gems, or rhinestones, and can be made of a variety of materials and also have a variety of specific shapes.
With continued reference to
To place a drill 40, a user first peels the protective film 33 back, exposing the adhesive 30. The user then dips the tip 54 of the applicator 50 into a wax pad 56. The wax 56 provides a light adhesive affect so that when the user applies the tip 54 onto the facet side of a drill 40 in the tray 46, the drill will stick to the tip 54 (as shown in
The protective layer 33 can be configured as a unitary film applied to the adhesive 30. However, with reference next to
In the variation shown in
In the variation depicted in
In some variations the sections B1-B11 can be configured to correspond to one or a limited number of colors of drills 40, so that when a user removes the protective film 33 within a particular section only a limited number of different types of drills 40 will be used for the exposed portion. In some variations the drills 40 can be packaged in bags 42 corresponding to particular sections. In such instances a label 44 of a bag 42 can correspond to a particular section B1-B11, which section number can be printed, for example, on the appropriate location of the protective film 33. A limited number of different types of drills 40 can correspond to that section, and each different type of drill 40 can be placed in its own bag (and with its own label) within the larger bag 42 that corresponds to the selected section. Thus, each section's drills 40 can be separately bagged for the convenience of the user in 1) exposing only the particular section being worked on in that diamond painting session; and 2) opening bags only for drills 40 being placed in that particular section. Thus, exposure of adhesive 30 is limited, and exposure of loose drills 40 is also limited to only those drills 40 relevant to the particular section.
As shown in
The protective film 33 can be formed of a variety of flexible materials, mostly plastics, that are configured to releasably adhere to the adhesive 30. In one variation the protective film 33 comprises a polyethylene terephthalate (PET) film having a thickness about 3.8 c (0.38 mm) and having a silica oil coating. Such a film, and other acceptable films, can be obtained from manufacturers such as Dow Corning. In one variation the tear lines 60 comprise lines of perforations through the protective film 33, and it is desired that the perforations are such that the protective film 33 tears readily along the tear lines 60. In one variation the PET film mentioned above is used as the protective film 33, and the tear lines 60 are made up of elongated perforations through the film, each elongated perforation having a cut length of 4 mm, and an uncut space between adjacent perforations is 0.5 mm. Other variations can include a similar, 8:1 ratio of cut/uncut portions defining the tear lines, or may employ greater or lesser ratios as desired and/or as allowed by the film material.
Upon manufacture, a diamond art canvas 22 typically is rolled up tightly and deposited in an elongated, cylindrical tube 70 for storage and shipping. Depending on the size of the canvas 22, it may be rolled so as to have a rolling diameter of about ½ inch to 5 inches, and more likely between about 1-3 inches. With reference next to
As discussed above, the diamond art canvas 22 comprises a substrate 24 having a front surface upon which the adhesive 30 is deposited and the protective film 33 is placed atop the adhesive 30. With reference next to
With continued reference to
Each of the above-described layers have properties that may be liable to wrinkling or remaining at least partly curled when the canvas 22 is unrolled for use. In some variations, a backing layer 90, comprising a composite of fibers entrained in an adhesive matrix, is applied to or behind the back sealing layer 82 and is configured to urge the substrate 24—and entire canvas 22—to lie flat and minimize wrinkling. The fibers of the backing layer 90 can be disposed embedded within an adhesive layer. The fibers embedded within the adhesive layer urges the diamond canvas to lay flat after it is removed from the shipping tube.
In some variations the backing layer 90 is applied to the back sealing layer 82 when the layers are in a flat disposition. Preferably, the fibers are applied so that their lengths are randomly embedded within an adhesive or the fibers may substantially lie in the plane of the backing layer 90 when lying flat. Also, preferably the fibers are applied randomly so that elongated fibers extend in all directions within the plane. Such application can be, for example, via entraining the fibers within an adhesive matrix that gets applied to the back sealing layer 82, by flocking the fibers onto an adhesive layer, by attaching and adhering a woven or non-woven cloth containing the fibers thereto, or the like when the canvas is flat.
The fibers should be chosen to have sufficient elasticity to accommodate rolling of the diamond art canvas 22 to a diameter of about 1-3 inches without exceeding the elastic limit of the fiber when the diamond art canvas is rolled up and placed in a shipping tube, but sufficient stiffness to urge the canvas 22 back to the fibers' at-rest position in which the diamond art canvas 22 can lay flat, substantially without wrinkles or curved edges. It has been determined that fibers having a length of about 1-10 mm (preferably 1 to 4 mm) and a tensile strength greater than about 700MPa, or more preferably greater than about 900 MPa, and/or a Young's Modulus of greater than about 15 GPa, more preferably greater than about 20 GPa, and even more preferably greater than about 25 GPa, will sufficiently bias the diamond art canvas 22 to lie flat so as to overcome most or all of the tendency of other layers to wrinkle or maintain a curve when being unrolled after being rolled up for some time. In order to accommodate such rolling, however, it has been determined that fibers should have a tensile strength less than about 2000 MPa, and more preferably less than about 1800 MPa, and/or a Young's modulus less than about 45 GPa, and more preferably less than about 40 GPa, so as to allow rolling of the canvas 22 as needed to place the canvas 22 in the tube 70 for storage and transport.
In some variations, the backing layer 90 comprises a composite material comprising bamboo fibers entrained in an adhesive matrix. The bamboo fibers can have an average length between about 10-40 mm and an average diameter of about 10-30 μm. Such bamboo fibers can be chemically or mechanically treated and can have a tensile strength between about 930-1770 MPa and/or a Young's modulus of between about 26.85-34.62 GPa, or about 26-35 GPa. The bamboo fibers preferably are applied within the backing layer 90 so as to, when at rest, lie at a plane. In other words, the bamboo fibers may be entrained in the adhesive matrix when the diamond art canvas is in a flat position. After entraining the bamboo fibers in the adhesive matrix, the adhesive matrix is allowed to cure while flat. In this regard, when the diamond art canvas is rolled up, the fibers bend within the adhesive matrix but does not exceed its elastic limit. When the diamond art canvas is removed from the tube, the fibers help to bias the diamond art canvas to the flat position or its original position when it was first cured (i.e., in the flat position). In some variations, the bamboo fiber backing layer 90 can comprise an adhesive upon which bamboo fiber are flocked, typically using a puffer or blown application method so that the fibers are randomly applied with their lengths oriented randomly and within the plane of the backing layer 90 (and applied adhesive). The adhesive can be applied to the back scaling layer 82 prior to application of the fibers. By curing the adhesive with the backing layer 90 in a flat, or planar, disposition, the at-rest configuration of the fibers is established to urge the diamond canvas toward a flat disposition when taken out of the tube. Once cured, the bamboo fiber-reinforced backing layer 90 will be flexible enough to allow the diamond art canvas 22 to be rolled up and placed within a tube 70. However, when the diamond art canvas 22 is removed from the tube 70 and unrolled, the bamboo fiber-reinforced backing layer 90 will urge the diamond art canvas 22 toward a flat orientation, resisting curled edges or wrinkles.
The composite backing layer 90 can be applied and configured in other ways. For example, in another variation fibers can be coated with adhesive and sprayed onto the back sealing layer 82. Alternatively, an adhesive can be applied to the back sealing layer 82 and a woven or non-woven fabric made up of fibers having the desired tensile strength and Young's modulus characteristics can be applied to the adhesive. Such application preferably is performed while the substrate 24 is flat so that the at-rest configuration of the backing layer 90 (and the fibers that make it up) is flat.
In some variations, the backing layer 90 can be applied to the back sealing layer 82 prior to printing an image on the print layer 86 or flash layer 88.
In still another variation, the textile layer can comprise a fabric made up of the same or similar fibers as are used in the backing layer. Such fibers can be bamboo fibers and/or other fibers having the desired tensile strength and Young's modulus characteristics as discussed herein. By way of example and not limitation, the various aspects discussed herein has been discussed in relation to bamboo fibers. However, other fibers can be used instead of or in combination with bamboo fibers. These other fibers include but are not limited to hemp fibers, fibers from the ramie plant, flax fibers, jute fiber, kenaf or hibiscus cannabinus fiber, sisal or agave sisalana fiber, pineapple or ananas comosus fiber, coconut coir fiber, or combinations thereof.
