FIELD OF THE INVENTION
The present invention relates to a moisture activated image. More specifically, the disclosure describes a process and related applications for applying an image onto an object, where the applied image remains concealed until the image is subjected to moisture.
BACKGROUND OF THE INVENTION
The present invention relates to a method and respective applications which apply a graphical image, a pattern, text, or any combination thereof onto an article, wherein the illustration appears, disappears, then re-appears through a multitude of cycles without compromising the durability of the article using a process defined as moisture activated invisible stencil technology.
It is common to apply or create an image, graphic, pattern or text on and into a fabric or material to enhance its aesthetic appearance. For instance, often times typical t-shirts are altered by applying artwork in a form of an image, a graphic, a pattern, and/or text to the front or back of the fabric or material of the t-shirt to share artwork, convey a message, display a logo, or present any other information. Other articles such as apparel, including shirts, pants, sweatshirts, sweatpants, coats, shoes, canvas shoes, hats, socks, and the like can also be adorned by the moisture activated invisible stencil technology. The technology can be expanded to other products, including backpacks, bedding including mattresses, bed sheets, cover sheets, mattress liners, and the like; table wear including tablecloths, napkins, and the like; pool decks; wet roadway warnings including road surface appliqués, road signs, and the like; absorbents, including sponges, towels, and the like; coolers; individual beverage coolers; umbrellas; and the like.
Artwork is commonly applied to the apparel or other material via an appliqué, silk screening, heat transfers, printing process, painting, embroidery, weaves, stone washing, tie dyes and/or other dyes, and the like. The artwork is generally of an opaque colored process, where the artwork remains visible throughout the life of the garment or other object. It is further noted that the artwork remains visible as applied to the material. More specifically, if the artwork were printed or applied to a single side of the material, it remains visible to and only to the first side of the material. If the artwork were applied to both sides of the material, such as embroidery, it remains visible to both sides of the material.
A first known related art utilizes nylon or other synthetic material that is treated to allow a variation in the shading of the fabric to appear as a pattern when the fabric is wet which is not visible when the fabric dries. The first known related art is limited wherein the nylon fabric does not allow the pattern to be visible on both sides of the fabric. The surface of the nylon fabric must be altered on the top of the fabric to allow the pattern to become visible on only the top of the fabric. The method is limited to nylon or very similar synthetic material, as process requires a branding or melting of the synthetic fabric surface of the nylon fabric to produce the effect. It is recognized that the synthetic nylon fabric dries very quickly, thus the image is only visible over a very short time period. Since the surface of the nylon fabric is altered, the image can become visible when the material is placed at an angle to the viewing party. The contrast created when the material is subject to moisture is limited at best, thus the artwork is only visible within a short viewing distance.
A second known related art utilizes a method forming of a distinct pattern on an article of apparel by applying a template onto a base substrate. A wax is applied over the stencil. The stencil is removed, leaving an exposed portion of the base substrate for application of a dye, paint, stain, or other color treatment. The exposed portion of the base substrate is colored. The wax is subsequently removed, leaving the applied image thereon.
A third known related art utilizes a method by which images on a disposable material fade when the material gets wet. The third known related art is limited where the visible image only fades when wet and fails to reappear when the material dries. The moisture causes degradation of the applied image, thus causing the image to fade away. This creates a single use application of the third known related art. The third known related art generally applies the images onto a disposable back-sheet which are typically made of a ‘breathable’ polyethylene film or a non-woven and film composite which is intended to prevent wetness transfer to the bed or clothes while helping the child to learn to stay dry. An example of this embodiment is a diaper, which includes an image. The image is dissolved by moisture to indicate that the image has been subjected to moisture. Since the image dissolves, it can't reappear when dry.
A fourth known related art utilizes a method of placing an opaque fabric over a secondary printed fabric such that when the opaque fabric subjected to moisture, the opaque fabric becomes partially transparent enabling the secondary printed fabric to show therethrough. The fourth known related art is limited in the requirement of two layers of material. The outer layer must be of a special type of opaque fabric, which would become partially transparent when wet. The opaque fabric must also remain in contact with the printed layer to ensure visibility of the artwork. Any gap therebetween would limit the viewing of the artwork of the second layer.
A fifth known related art is a toy that utilizes a frame which holds paper that has a highly colored substrate covered by a layer of silica and resins which becomes transparent when wet and opaque when dry so that the bright color does or does not show through depending on whether the surface is wet or dry. A fifth known related art is limited wherein the apparatus requires a layer of silica and resin across its entire surface. The concept severely limits any potential applications, as the material is not robust. Paper is not susceptible to applications for apparel, repeated use, heavy traffic such as floors, roadways, etc., and the like. The design is not capable of being cleaned.
A sixth known related art utilizes printed artwork using inks that remain concealed until exposed to an activator are currently available, wherein the activator is Ultra-Violet light. The image is commonly outlined with non-changing ink, such as a black outline, a colored image, and the like. The UV activated ink is generally colored and applied within the printed line drawing, where the UV activated inks become visible, revealing a color enhancement to the illustration. The ink required for this application is expensive. Applications using this ink are limited, as the process requires UV light to reveal the image.
Objects that are wet can create hazardous conditions. Wet roads generally have less traction than dry roads. Signs are commonly used to warn drives that roads may become slippery when wet. This process is limited, where the driver is not informed if the roads are actually wet. Wet pool decks can become slippery. Pool decks are subjected to a warning system similar to the process described for roads; relying upon signs. Floors, such as retail outlets, supermarkets, office buildings, and the like can become slippery when wet. When a floor becomes wet, the process commonly requires deployment of a warning marker, such as a cone or other warning device. A significant limitation is the time between when traction is reduced on a surface due to moisture and when a warning of the pending hazard is presented.
While the disclosed references may be suitable for the particular purpose to which they address, they fail to enable hidden or “phantom” artwork to appear when moisture is applied to the material and subsequently disappear when the material dries.
There is a need for a method of applying an illustration onto an object, where the illustration is revealed when subjected to moisture and disappears when the article dries. The desired process should be repeatable over a multitude of cycles without compromising the durability of the article. The illustration can be provided in the form of a graphical image, a pattern, text, or any combination thereof. The method should be repeatable, the process should not require costly equipment, and such method should not affect the use of the article and in which the article is unchanged by the process. It is desired to provide a method that can provide immediate notification of a hazardous surface.

DETAILED DESCRIPTION OF THE INVENTION
The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments or the application and uses of the described embodiments. As used herein, the word “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to make or use the embodiments of the disclosure and are not intended to limit the scope of the disclosure, which is defined by the claims. For purposes of description herein, the terms “upper”, “lower”, “left”, “rear”, “right”, “front”, “vertical”, “horizontal”, and derivatives thereof shall relate to the invention as oriented in FIG. 1. For purposes of description herein, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
A moisture activated image can be created by applying a moisture blocking agent to any moisture absorbent material as illustrated in a first exemplary embodiment presented in FIGS. 1 through 3. The moisture activated image is applied in a pattern representative of desired artwork. The artwork includes a graphical image, a pattern, text, or any combination thereof. The pattern is created by any means known by those skilled in the art. The exemplary embodiment utilizes a screen printing process to apply the moisture blocking agent onto the object; an apparel 200 in the exemplar embodiment. The applied moisture blocking agent 220 prevents wetting of any moisture into the apparel material 210, whereas areas of the apparel material 210 having exposed material (void of the moisture blocking agent) absorb the moisture and thus change shade or color to reveal the moisture activatable image 222. When the apparel material 210 dries, the moisture activatable image 222 returns to a concealed configuration. The appearance and disappearance of the moisture activatable image 222 is repeated throughout the life of the product.
The applied moisture blocking agent 220 can be any type of moisture repelling or blocking chemical compound including, a four carbon fluorocarbon chain and a sulfonic acid functional group acting as an anion or ion with more electrons than protons, giving a net negative charge which functions as a stable fluorosurfactant because of the strength of carbon-fluorine bonds, a synthetic hydrophobic surface-applied compound, a fluoropolymer, and the like, and any combinations thereof.
The applied moisture blocking agent 220 is applied by an exemplary printing process. It is understood that any application process can be used to create the moisture activatable image 222. The application process can be referred to as moisture activated, invisible stencil technology. The printing process utilizes a screen printer 100, the screen printer 100 comprising a printing screen 112 held in tension by a screen printing frame 110. A blocked screen image 120 is applied to a portion of the printing screen 112, wherein the blocked screen image 120 blocks transfer of the applied moisture blocking agent 220 to the apparel material 210. The blocked screen image 120 can be created by any stencil generation process; including a manual cut stencil, a photo developed stencil, a laser cut stencil, and the like. The stencil is applied to the printing screen 112 creating a blocked screen image 120. The balance of the printing screen 112 remains as an exposed screen background 122, allowing the applied moisture blocking agent 220 to pass therethrough. A screen lower surface 116 of the printing screen 112 is positioned to contact a desired application surface of the apparel material 210 in registration with the desired image location. The applied moisture blocking agent 220, in a liquid or paste form, is applied upon a screen upper surface 114 and wiped across the entire exposed surface of the printing screen 112. The applied moisture blocking agent 220 passes through the exposed screen section 122, transferring the applied moisture blocking agent 220 therethrough onto a receiving surface of the apparel material 210. The moisture blocking agent 220 is refrained from transfer by the blocked screen image 120 applied to the printing screen 112. The applied moisture blocking agent 220 penetrates into the weave of the apparel material 210, preferably penetrating through the apparel material 210 forming a barrier that protects the apparel material 210 against moisture without leaving the fabric or material discolored, stiff or sticky.
The contrast between a dry configuration and a wet configuration is demonstrated in the illustration of FIG. 3. The apparel 200 is shown having a dry view 242 and an adjacently shown moisture saturated view 252. The moisture activatable image 222 remains concealed to the naked eye when dry and becomes visible as a moisture activated image 224 when subjected to applied moisture 250. The applied moisture blocking agent 220 deters and adherence or wetting of applied moisture 250. The moisture activatable image 222 is exposed apparel material 210, wherein the apparel material 210 absorbs the applied moisture 250 and changes either shade or color, based upon the selected apparel material 210. Commonly, the wetted area creates a darker contrast to the dry portion of the apparel material 210. The process allows the apparel material 210 to retain long-lasting penetrating protection and can be used in apparel including shirts, pants, footwear, outerwear, sports gear, camping gear, hunting gear, furniture, upholstery, and the like. The base substrate material can be 100% cotton, a cotton blend, any fabric surfaces, canvas, polyester, polyester blend, leather, flannel, fleece, wood, concrete, cement, asphalt, and the like. The base substrate material can be expanded into certain versions of materials where the versions can absorb or retain moisture, including certain finishes of granite, marbles, unglazed ceramic and China, and the like. The disclosed moisture activated invisible stencil process does not affect the integrity of any of the aforementioned materials and can withstand repeated washings. The drying process or the use of a dryer also reactivates the blocking agent.
Alternatively, the blocking agent may be applied as a liquid, gas, solid, or plasma, which then disappears to leave a pattern of both treated or blocked areas and untreated or unblocked areas. The blocking agent may be applied to the apparel material 210 by various methods, including a spray can, air brush, brush, sponge, pen applicator, paint roller, and the like.
The graphic image 222 does not appear in dry conditions 242 on the fabric or material 210 exhibiting the blocking agent properties 220, but when subjected to a liquid 250, exposes through the use of a stencil or template bearing the desired marking pattern, the blocking agent 220 prevents a change in the fabric or material 210 of the blocking agent area 220 so that the artwork 222 remains invisible under ordinary dry conditions 242, and becomes visible 224 when exposed to moisture 250.
The first example presents a positive image, where the moisture activatable image 222 is in a form of the actual image and becomes visible when subjected to applied moisture 250. A positive image can be defined where the colorless moisture blocking agent 220 is applied representing a positive image of said artwork, wherein said blocking agent 220 is applied as a background, outlining lines of said artwork 222 and repels moisture where lines of said artwork 222 remains exposed for absorption of moisture.
It is understood that the image may be presented in a negative form, as illustrated in FIGS. 4 and 5. The screen image is reversed, wherein the screen image includes a blocked screen background 132, leaving an exposed screen image 130 in accordance with the artwork. The applied moisture blocking image 230 is applied to the apparel material 210, leaving a moisture activatable image background 232. When the apparel material 210 is subjected to applied moisture 250, the moisture activatable image background 232 wets causing the moisture activatable image background 232 to transition into a moisture activated background 236. The change to the moisture activatable image background 232 contrasts the applied moisture blocking image 230, wherein the applied moisture blocking image 230 becomes a visible blocked image 234. A positive image can be defined where the colorless moisture blocking agent 220 is applied representing a negative image of said artwork 232, wherein said blocking agent is applied as lines of said artwork 230 and repels moisture wherein the background 232 remains exposed for absorption of moisture.
The first two examples are presented to describe the process using an aesthetic application. The concept can be expanded into a variety of functional applications, having several examples presented in FIGS. 6 through 14. The technology can be expanded to other products, including backpacks, bedding including mattresses, bed sheets, cover sheets, mattress liners, and the like; table wear including tablecloths, napkins, and the like; pool decks; wet roadway warnings including road surface appliqués, road signs, and the like; absorbents, including sponges, towels, and the like; coolers; individual beverage coolers; umbrellas; and the like.
A first exemplary embodiment provides a calorie correlating apparel 300, presented in the illustration of FIG. 6. The calorie correlating apparel 300 includes a plurality of applied moisture blocking image 330 disbursed about the apparel material 310. The calorie correlating apparel 300 is placed upon the individual's torso prior to exercising. As the individual exercises, the individual perspires. As the perspiration wets the moisture activatable image background 332 (exposed, unblocked portion of the apparel material 310), represented as a perspiration wetted section 350, the moisture activatable image background 332 transitions into a moisture activated background 336, which in turn makes the respective portion of the applied moisture blocking images 330 transition into a visible blocked image 334. The individual can then count the quantity of visible blocked images 334 and would then correlate the quantity of visible blocked images 334 to the calories burnt during the exercise routine. The exemplary embodiment presents a negative image. It is understood that the same concept can utilize a positive image. The pattern can be arranged of any number of applied moisture blocking images 330 having any shape, and any spatial arrangement. It is desirous to have the pattern arranged to simplify the step of counting the visible blocked image 334.
A second exemplary embodiment provides a moisture indicating mattress 400, presented in the illustration of FIG. 7. The moisture indicating mattress 400 disposes the moisture activated invisible stencil technology upon a sleeping surface 412 of a mattress 410.

The moisture activatable image 422 can include artwork that would convey to an individual that the sleeping surface 412 has been wet. The moisture activated invisible stencil technology can be applied to a mattress, a bed sheet, a sheet cover, a blanket, and the like. The artwork can be located in a common central portion of the mattress or in smaller repeated images spatially arranged about a portion or the entire surface. When the sleeping surface 412 is wet, the moisture activatable image 422 transitions from a concealed image to a visible image. The exemplary embodiment presents a negative image. It is understood that the same concept can utilize a positive image.
A third exemplary embodiment provides a moisture indicating handkerchief 500, presented in the illustration of FIG. 8. The moisture indicating handkerchief 500 disposes the moisture activated invisible stencil technology upon a handkerchief material 510 to fabricate the moisture indicating handkerchief 500. The moisture activated invisible stencil technology is represented as an applied moisture blocking material 520 and a respective moisture activatable image 522. The moisture activatable image 522 can include artwork that would convey to an individual that the handkerchief material 510 has been subjected to moisture. The artwork can be located in a common central portion of the handkerchief material 510 or in smaller repeated images spatially arranged about a portion or the entire surface thereof. The moisture activatable image 522 does not appear in a dry view 542 of the handkerchief material 510, but when subjected to an applied moisture 550, as illustrated in a moisture saturated view 552, the moisture is absorbed by the moisture activatable image 522, which transitions the moisture activatable image 522 to a moisture activated image 524. The moisture activated image 524 converts back to a moisture activatable image 522 when the handkerchief material 510 returns to an ordinary dry condition. The exemplary embodiment presents a negative image. It is understood that the same concept can utilize a positive image.
A fourth exemplary embodiment provides a tablecloth 600, presented in the illustration of FIG. 9. The tablecloth 600 disposes the moisture activated invisible stencil technology upon a tablecloth primary surface 610. The tablecloth primary surface 610 is placed upon an upper surface of a table 650, creating a tablecloth skirt 612 about a peripheral edge thereof. The moisture activated invisible stencil technology is represented as a moisture activatable image 622 defined by an applied moisture blocking material 620. The moisture activatable image 622 can include artwork that would convey to an individual that the tablecloth primary surface 610 has been wet. The moisture activated invisible stencil technology can be applied to the tablecloth, a tablecloth cover, napkins, placemats, and the like. The artwork can be located in a common central portion of the tablecloth primary surface 610 or in smaller repeated images spatially arranged about a portion or the entire surface. When the tablecloth primary surface 610 is wet, the moisture activatable image 622 transitions from a concealed image to a visible image. The exemplary embodiment presents a positive image. It is understood that the same concept can utilize a negative image.
A fifth exemplary embodiment presents a pool area 700 comprising a wet surface warning system, presented in the illustration of FIG. 10. The pool area 700 includes a swimming pool 750 surrounded by a swimming pool deck 710. A pair of pool entry safety bars 760 provides aid to a swimmer during entry and exit of the swimming pool 750. A moisture activatable image 722 is applied upon a surface of the swimming pool deck 710. It is desired that a plurality of moisture activatable images 722 are spatially arranged about the swimming pool 750. It is further desired that the moisture activatable images 722 are applied in different orientations to warn individuals walking in any direction of a potentially slippery deck surface. The moisture activatable image 722 can be placed upon a water absorbent material, such as a fabric, sponge, rubber, concrete, and the like. When water splashes onto the swimming pool deck 710, the moisture activatable image 722 transitions into a visible state, thus warning individuals of the potentially slippery deck surface.

The moisture activated image 1130 is applied in either a positive image or a negative image. When moisture is applied to the drink cooler wrap exterior surface 1112, the image transitions from being hidden to a visible image. When the drink cooler wrap exterior surface 1112 dries, the image returns to a hidden state.
A summary of the present invention is described in a moisture activated invisible stencil technology flow diagram 1200 presented in FIG. 15. The process initiates with a step of creating desired artwork for the application (block 1210). The artwork is then used to create an image applicator for application of the moisture activated invisible stencil technology onto an object, wherein the stencil is representative of the artwork (block 1212). The applied moisture blocking agent 220 is applied to the object in accordance with the selected application method (block 1214). The applied moisture blocking agent 220 can be any type of moisture repelling or blocking chemical compound including, a four carbon fluorocarbon chain and a sulfonic acid functional group acting as an anion or ion with more electrons than protons, giving a net negative charge which functions as a stable fluorosurfactant because of the strength of carbon-fluorine bonds, a synthetic hydrophobic surface-applied compound, a fluoropolymer, and the like, and any combinations thereof. The applied moisture blocking agent 220 can be provided in any form factor, including a liquid, cream, paste, gas, solid, aerosol, plasma, and the like. The application method can include: screen printing, spray can, air brush, brush, sponge, pen applicator, paint roller, and the like. The process provides time for the applied moisture blocking agent 220 to dry or cure. The product is completed, packaged, and distributed for use (block 1220). Moisture is applied to the product containing the moisture activated image (block 1230). The moisture wets the unblocked portion of the image, causing the unblocked portion of the image to change in shade or color exposing the concealed image (block 1232). It is preferred that the base substrate material be moisture absorbent. The product containing the moisture activated image is subsequently dried (block 1234) returning the moisture activated image into a concealed state (block 1236).
It is understood that the concept of the moisture activated image can be used for authentication of goods, wherein the moisture activated image would be applied to an object. The object would be subjected to moisture to activate and present the moisture activated image. The moisture activated image would be verification of authenticity of the object. Essentially, this application would parallel functionality of a watermark.
Alternatively, the blocking agent may be a dewetting agent applied to a wettable surface, such as glass, glazed ceramic, and the like, wherein the applied dewetting agent repels moisture and the exposed surface wets. An example of a dewetting agent is a water repellant sold under the brand name Rain-X®.
Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
