Abstract
An example printable structure comprises a first fabric layer that includes a first side that is printable with water-based ink. The first fabric layer is permissive to migration of the water based ink through the first fabric layer. A first adhesive layer is bonded to a second side of the first fabric layer. An ink migration barrier is bonded to the first adhesive layer opposite the first fabric layer, a second adhesive layer is bonded to the ink migration barrier opposite the first adhesive layer, and a second fabric layer is bonded to the second adhesive layer opposite the ink migration barrier. The second fabric layer is permissive to migration of the water-based ink through the second fabric layer. The ink migration barrier is configured to provide resistance to ink bleed from the first fabric layer to the second fabric layer.
Description
- This application is a continuation of U.S. patent application Ser. No. 15/728,356, filed Oct. 9, 2017, the entirety of which is hereby incorporated herein by reference for all purposes.
- Dyes and inks may be used to adorn the surfaces of fabrics with designs, patterns, and/or images. Such fabrics may be incorporated into a variety of end products.
- This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.
- In one example, a printable structure comprises a first fabric layer that includes a first side that is printable with water-based ink. The first fabric layer is permissive to migration of the water based ink through the first fabric layer. A first adhesive layer is bonded to a second side of the first fabric layer. An ink migration barrier is bonded to the first adhesive layer opposite the first fabric layer, a second adhesive layer is bonded to the ink migration barrier opposite the first adhesive layer, and a second fabric layer is bonded to the second adhesive layer opposite the ink migration barrier. The second fabric layer is permissive to migration of the water-based ink through the second fabric layer. The ink migration barrier is configured to provide resistance to ink bleed from the first fabric layer to the second fabric layer.

FIG. 1 schematically shows a multi-layered printable structure. -
FIG. 2 schematically shows an ink migration barrier. -
FIG. 3 schematically shows a product assembly encased in a multi-layered printable structure including an ink migration barrier. -
FIG. 4A shows a first side of an example electronic device encased in a multi-layered printable structure including an ink migration barrier. -
FIG. 4B shows a second side of an example electronic device encased in a multi-layered printable structure including an ink migration barrier. -
FIG. 5 shows a flow chart illustrating an example method for encasing a product in a multi-layered printable structure. - Numerous consumer and commercial products feature two or more layers of fabric bonded together, often using one or more layers of adhesive there between. Designs, patterns, and/or images may be printed onto one or more sides of the layered fabric structure. However, when two fabric layers are bonded together back-to-back, if artwork is printed on one fabric or both fabrics, the ink printed on the first fabric may migrate over time to the second fabric. This may create an undesirable appearance defect when the ink bleeds onto the cosmetic (e.g., exterior) layer of the second fabric.
- This problem may be particularly an issue for water-based inks that are printed onto fabrics containing polyurethane (PU). In such fabrics, the PU material content may increase a rate of ink migration compared to other fabrics, potentially leading to a visible haloing effect. This effect occurs even if the fabric includes fibers that bind more strongly to water-based ink pigments, such as polyester fibers. However, polyurethane may impart numerous other desirable qualities to synthetic fabrics. For example, a polyurethane may impart flexibility, conformability, tensile properties, tear resistance, softness, touchability, and make the fabric easier to process.
- Accordingly, examples are disclosed that relate to mitigating dye migration through a layered fabric structure by placing an ink migration barrier in between two fabrics that are bonded back-to-back. Such an ink migration barrier may be constructed to allow for the layered fabric structure to retain flexibility without concerns for dye migration, regardless of what portions of the fabric are printed. Layered fabric structures including an ink migration barrier may be applied to single-sided printed fabrics, and may further be applied to product covers where one or both sides of the product are adorned with a printed design.
-
FIG. 1 shows an example multi-layeredprintable structure 100. Multi-layeredprintable structure 100 includes afirst fabric layer 110 having afirst side 112 and asecond side 114.First side 112 may be an external side, and may be a printable side offirst fabric layer 110. Multi-layeredprintable structure 100 further includes asecond fabric layer 120 also including afirst side 122 and asecond side 124.First side 122 may be an external side, and may be a printable side offirst fabric layer 120. -
First fabric layer 110 andsecond fabric layer 120 may be any suitable fabrics that are printable with water-based inks. As mentioned above,first fabric layer 110 andsecond fabric layer 120 may be permissive to migration of the water-based ink. For example, water-based ink printed onfirst side 112 offirst fabric layer 110 may migrate throughfirst fabric layer 120 tosecond side 114. Similarly, water-based ink printed onfirst side 122 ofsecond fabric layer 110 may migrate throughsecond fabric layer 120 tosecond side 124. - In some examples,
first fabric layer 110 andsecond fabric layer 120 may include at least polyurethane. As a more specific example, polyurethane fibers may be included in a synthetic fabric that further includes other fibrous material such as polyester fibers. As an example, the fabric layers may be generated from fibers that include a blend of at least polyester and polyurethane. In some examples, the fibrous polyester material may be bound, for example, using polyurethane. Other materials may additionally or alternatively be used as a binder for microfiber fabrics, such as polyamide and/or other suitable materials. - Additionally or alternatively, one or more of
first fabric layer 110 andsecond fabric layer 120 may be other dye-migratory microfiber-based fabrics, woven fabrics, etc. For example,first fabric layer 110 andsecond fabric layer 120 may include woven polyester fabric, knit polyester fabric, and/or other woven or knit fabrics that may or may not include polyurethane.First fabric layer 110 andsecond fabric layer 120 may be different fabrics and/or fabrics that include the same sub-components in different ratios or configurations. As examples,first fabric layer 110 and/orsecond fabric layer 120 may comprise one or more of PE fibers, polyamide fibers (e.g., nylon), cellulosic fibers, polypropylene fibers, polystyrene fibers, acrylonitrile butadiene styrene fibers, poly (vinyl butyral) fibers, and/or other fiber and microfiber types. - While described in the context of water-based inks and fabric layer materials which permit migration of water-based inks, it should be understood that other combinations of inks and fabrics may be used within multi-layered
printable structure 100 and other printable structures described herein, provided the fabric(s) are conducive to migration of the selected inks and/or dyes. For example, polyester-based fabrics, among other fabric types, may be conducive to the migration of oil-based inks, such as plastisol inks, organic solvent-based inks, latex inks, UV-curable inks, etc. - One or both of
first fabric layer 110 andsecond fabric layer 120 may be printable with water-based ink. In particular,first side 112 offirst fabric layer 110 and/orfirst side 122 ofsecond fabric layer 120 may receive printed dyes and/or inks. Water-based ink may be directly printed onto first and/orsecond fabric layers - As an example, dye sublimation ink pigments may be applied to
first side 112 offirst fabric layer 110 and/orfirst side 122 ofsecond fabric layer 120 through a sublimation process. Dye sublimation inks are typically water-soluble, allowing the inks to penetrate fibers in the fabric layer without modifying the characteristics of the fibers themselves. Dye sublimation inks may be ink-jet printed onto a carrier paper. The carrier paper may then be dried and put in to close contact with the selected fabric layer. Heat and pressure may then be applied over time, for example, using a heat press machine. The dye sublimation inks may then sublimate from the carrier paper to the fabric layer, where the ink may bind to the polyester fiber components of the fabric layer. However, porous fabric layers such as knit or woven polyester fibers may permit dye migration through the fabric layer. Further, the dyes may not bind well to polyurethane components of the fabric layer, allowing excess ink to migrate through the fabric layer. - To prevent migration of inks between
first fabric layer 110 andsecond fabric layer 120, anink migration barrier 130 may be deposed between the two fabric layers. In this example,printable structure 100 further comprises a firstadhesive layer 140 bonded tosecond side 114 offirst fabric layer 110 andink migration barrier 130 is bonded to firstadhesive layer 140 opposite fromfirst fabric layer 110. A secondadhesive layer 150 is bonded toink migration barrier 130 opposite from firstadhesive layer 140. Secondadhesive layer 150 is bonded tosecond side 124 ofsecond fabric layer 120 opposite fromink migration barrier 130. - First and second
adhesive layers fabric layers ink migration barrier 130. For example, first and secondadhesive layers adhesive layers - The thickness of first and second
adhesive layers adhesive layers adhesive layers adhesive layers adhesive layers adhesive layers -
Ink migration barrier 130 may comprise any suitable material that prevents and/or significantly reduces the migration of ink between first and second fabric layers 110 and 120.Ink migration barrier 130 may be a non-porous film that either binds or repels water-based ink or otherwise inhibits water-based ink from traversing the film.Ink migration barrier 130 may be bondable to other films and/or fabrics. For example,ink migration barrier 130 may include a heat-sensitive thin film. - In some examples,
ink migration barrier 130 may comprise a multi-layered film. For example,FIG. 2 schematically shows a multi-layeredink migration barrier 200 as an example ofink migration barrier 130.Ink migration barrier 200 includes afirst barrier layer 210.First barrier layer 210 may include a polyurethane resin-based film, which may include one or more additional materials (e.g., PET as a dopant). In some examples,first barrier layer 210 may alternatively or additionally include biaxially-oriented polyethylene terephthalate (BoPET), woven and/or non-woven polyester fabrics, polypropylene, PET, silicone membranes, polyimide films, etc. - A
first barrier layer 210 that is comprised of a polyurethane resin-based film may be advantageous in that, not only does the barrier block ink bleeding between two fabric layers that are bonded back-to-back, but the first barrier layer may be sufficiently thin to allow for minimal impact on the overall thickness of the printable structure. For example,first barrier layer 210 may have a thickness of less than 0.1 mm (e.g., 0.04 mm). - However, when applied directly to an adhesive layer, thin polyurethane resin-based films may soften before coating. As such, it may be advantageous to laminate other films to
first barrier layer 210 prior to bondingink migration barrier 200 to adhesive layers. As an example,ink migration barrier 200 may include one or more hot-melt film adhesive layers bonded tofirst barrier layer 210. As shown inFIG. 2 ,ink migration barrier 200 includes a first hot-melt filmadhesive layer 220 and a second hot-melt filmadhesive layer 230 applied to each side offirst barrier layer 210. - As an example, hot-melt film
adhesive layers adhesive layers adhesive layers adhesive layers - Multi-layered
printable structure 100 may be used for any suitable application in which two-sided fabric that is asymmetrically printed (e.g., printing on one side, different printing on opposing sides) is desired. As non-limiting examples, multi-layeredprintable structure 100 may be used in clothing garments, handbags, outdoor furniture, athletic equipment, window curtains and drapes, towels, table linens, umbrellas, wind/sun shields, bedding linens and textiles, etc. - In addition to two-sided fabric applications, multi-layered printable structures may also be used to decorate the exterior of a product. For example,
FIG. 3 schematically shows anexample product assembly 300.Product assembly 300 includes adevice 305 encased in a multi-layeredprintable structure 310 including anink migration barrier 315.Ink migration barrier 315 may be an example ofink migration barrier 200, and may thus include a polyurethane resin-based ink-migration barrier sandwiched between two hot-melt film adhesives. - As shown in
FIG. 3 ,device 305 is a relatively flat device including afirst side 317 and asecond side 319 that is relatively parallel to first side 317 (e.g., within 5 degrees of parallel). For example,device 305 may be a keyboard for a tablet computer, a tablet computer, a laptop computer, a smart phone, a wearable electronic device (e.g. wrist-worn device, head-mounted device), or other portable device. In other examples,device 305 may be an automotive sun visor, a stand and/or case for a secondary device, or other non-electronic device or soft-good. Other examples and configurations also are possible.Device 305 may be a relatively inflexible device, as compared to multi-layeredprintable structure 310. In other examples,device 305 may be a relatively flexible device that adjusts conformation in concert with multi-layeredprintable structure 310 when pressure is applied toproduct assembly 300.Device 305 may be composed of materials that are impermissive to the migration of ink or dye. - Multi-layered
printable structure 310 may be used to encasedevice 305, and thus provide a covering that is decorative and/or functional (e.g., comfortable, soft to the touch, tactile, protective). Multi-layeredprintable structure 310 includes afirst encasing subassembly 320 and asecond encasing subassembly 325. First encasingsubassembly 320 includesfirst fabric layer 327, firstadhesive layer 330,ink migration barrier 315, and secondadhesive layer 333. However, in some examples,ink migration barrier 315 and/or secondadhesive layer 333 may be included insecond encasing subassembly 325. -
First fabric layer 327 may include a first,printable side 335, and asecond side 337, oppositefirst side 335. As described with regard toFIG. 1 ,first fabric layer 327 may be a composite fabric structure that is permissive to migration of water-based ink, such as a structure that includes fibers containing a blend of polyester and polyurethane.First side 335 may be printed with water-based ink, such as dye-sublimation ink. Either prior to, or following printing and drying,first fabric layer 327 may be die-cut to a geometry that is close to a desired final geometry for encasingdevice 305. The die-cut fabric may include features (e.g., holes) that enable loading of the fabric onto a device for laminating and/or bondingfirst fabric layer 327 to other components offirst encasing subassembly 320 and/orsecond encasing subassembly 325. -
Ink migration barrier 315 may be assembled by heating and pre-tacking hot-melt film adhesive layers to both sides of a polyurethane resin-based barrier layer in a roll form, for example. The assembled ink migration barrier roll may then be die-cut to a geometry similar to that offirst fabric layer 327. Bothink migration barrier 315 andfirst fabric layer 327 may then be placed in fixture to be pre-tacked together. - First
adhesive layer 330 and secondadhesive layer 333 may include heat-activated adhesive films, such as ester-based polyurethane films, nylon-based polyamide films, etc., though pressure-sensitive adhesive films and UV curable adhesive films may also be used. Firstadhesive layer 330 and secondadhesive layer 333 may be applied to opposite sides of assembledink migration barrier 315, for example, by thermal bonding. As an example, the adhesive layers may be applied toink migration barrier 315 in roll form, staged and settled, then die-cut to a near-final geometry. In some examples, one or both adhesive layers may be die-cut prior to being applied toink migration barrier 315. -
Second encasing subassembly 325 includessecond fabric layer 340 and thirdadhesive layer 342.Second fabric layer 340 includes afirst side 345, and a second,printable side 347, oppositefirst side 345. As described with regard toFIG. 1 ,second fabric layer 340 may be a composite fabric structure that is permissive to migration of water-based ink, such as a structure that includes fibers containing a blend of polyester and polyurethane. As per first and secondadhesive layers adhesive layer 342 may include one or more heat-activated adhesive films, pressure-sensitive adhesive films, and/or UV curable adhesive films.Second side 347 ofsecond fabric layer 340 may be printed and dried, and thirdadhesive layer 342 may be applied tofirst side 345 ofsecond fabric layer 340, for example, by thermal bonding.Second encasing subassembly 325 may then be die cut for assembly arounddevice 305. However, in some examples, one or both ofsecond fabric layer 340 and thirdadhesive layer 342 may be die-cut prior to being bonded together. - First encasing
subassembly 320 andsecond encasing subassembly 325 may be placed on opposing sides ofdevice 305. In this configuration,first side 317 ofdevice 305 is in contact with secondadhesive layer 333, on the opposite side of secondadhesive layer 333 fromink migration barrier 315.Second side 319 ofdevice 305 is in contact with thirdadhesive layer 342, on the opposite side of secondadhesive layer 342 fromfirst side 345 ofsecond fabric layer 340. - When encasing
subassemblies device 305, the subassemblies may undergo a product lamination process (e.g., heat lamination), wherebyfirst encasing subassembly 320 is bonded todevice 305 andsecond encasing subassembly 325 via secondadhesive layer 333, andsecond encasing subassembly 325 is bonded todevice 305 andfirst encasing subassembly 320 via thirdadhesive layer 342. This generatesproduct assembly 300, whereindevice 305 now has a decorative and/or functional covering. - The final lamination process generates fabric-on-
fabric regions first fabric layer 327 andsecond fabric layer 340 are coupled together withoutdevice 305 in between. At the edges ofproduct assembly 300, fabric-on-fabric regions ink migration barrier 315 within the fabric-on-fabric regions limits the bleed-through of ink from one fabric layer to the other. - As an example, a product assembly as described with regard to
FIG. 3 may be an electronic device.FIGS. 4A and 4B depict aproduct assembly 400 including adetachable keyboard 405 that may be encased in a printedcover 410.Product assembly 400 may be an example ofproduct assembly 300, anddetachable keyboard 405 may be an example ofdevice 305. Printedcover 410 may be an example of multi-layerprintable structure 310, including two printable fabric layers, two adhesive layers, and an ink migration barrier. -
Detachable keyboard 405 may include auser input region 415, including akeyboard 420 and atouch pad 425. As shown,detachable keyboard 405 further includes amid-spine region 430 and aspine region 435.Spine region 435 includes a plurality ofconnectors 437, which may be used to physically and communicatively coupledetachable keyboard 405 to an external electronic device, such as a display screen, tablet computer, etc. -
Mid-spine region 430 may include an inflexible or less flexible segment that spans the width ofdetachable keyboard 405. Mid-spine region may be used to house components and circuitry ofdetachable keyboard 405, and may further provide a magnetic and/or physical anchoring point for allowingdetachable keyboard 405 and an attached display device to be used akin to a laptop form function. - A first
flexible region 440 may be located betweenspine region 435 andmid-spine region 430. A secondflexible region 445 may be located betweenmid-spine region 430 anduser input region 415. First and second flexible regions may house componentry, such as flex circuitry and cables, connectinguser input region 415,mid-spine region 430, andspine region 435. Firstflexible region 440 and secondflexible region 445 may allow fordetachable keyboard 405 to adopt numerous configurations for operation and storage, either alone or when connected to an external device viaconnectors 437. -
FIG. 4A shows afirst side 450 ofcover 410.First side 450 includes a first fabric layer featuring printedartwork 455.FIG. 4B shows asecond side 460 ofcover 410.Second side 460 includes a second fabric layer which may be die-cut so thatcover 410 is not bonded tokeyboard 420,touch pad 425, orconnectors 437. The lamination process may generate aborder 465, wherein the two fabric layers are bonded together (via adhesive layers and an ink migration barrier) without a portion ofdetachable keyboard 405 there between. - As such,
border 465, firstflexible region 440, and secondflexible region 445 may include regions of fabric-on-fabric bonding. As shown inFIG. 4A , printedartwork 455 places ink within each of these regions. Without an ink migration barrier present incover 410, ink may thus migrate fromfirst side 450 tosecond side 460, generating discoloration and visible artifacts within six months or sooner after product assembly. In some examples, an ink migration barrier, such as BoPET strips, may be laminated exclusively onto the regions with fabric-on-fabric bonding, but this configuration may only serve to slow dye migration and may not stop dye bleed-through altogether. By including an ink migration barrier, such as a polyurethane-based film, dye migration may be prevented over the lifetime of the product, thus allowing artwork to be printed anywhere onfirst side 450 without risking dye migration tosecond side 460. Further, by using a thin, flexible ink migration barrier, the flexibility offlexible regions border 465 may maintain a pliability, rather than taking on a rigidity that may be less pleasant for a user to touch. -
FIG. 5 shows a flow-chart for anexample method 500 for encasing a product with a multi-layered printable structure. In some examples, various steps ofmethod 500 may be performed at distinct locations and/or in separate, temporally different processes. - At 510,

The first and second adhesive layers may be heat-activated adhesive films, such as ester-based polyurethane films. As such, the first and second adhesive layers may be applied to opposite sides of the assembled ink migration barrier by thermal bonding, such as thermal lamination. The adhesive layers may be die-cut to a desired geometry following, or prior to being applied to the assembled ink migration barrier. The first fabric layer may be printed with a water-based ink, dried, and die-cut to a desired geometry.
