Abstract
A sealable vacuum chamber has an outlet. A template within the chamber includes flow guides for guiding colorant under vacuum across and into porous material when in contact therewith toward the outlet to create a pattern in the porous material. The flow guides allow for at least slight variation in the pattern without being altered.
Description




BACKGROUND OF THE INVENTION




Technical Field




The present invention generally relates to creating colorant patterns in porous materials. More particularly, the present invention relates to creating colorant patterns in porous materials in a vacuum environment.




Background Information




In the past, patterns were created in porous materials, such as fabric for clothing, by hand, and by processes such as imprinting, stenciling, silk screening, dyeing, transfer, ink jet, tie dye, etc. Each has drawbacks and limitations. For example, creating fabric designs by hand (e.g., by ink application), by tie dye or by silk screening is time consuming and relatively low-volume producing. As another example, imprinting, stenciling and other similar methods place the exact same design on all the fabric created, resulting in a lack of uniqueness in the finished product, which may not be desirable for some applications. As still a further example, silk screening allows for no variation, is a relatively expensive pattern-creation technique, only allows the application of one color per screen, and lacks full penetration of colorant through fabric.




Thus, a need exists for a relatively fast, low-cost way to produce volumes of at least slightly varying, high-quality, high-penetration colorant patterns in porous material.




SUMMARY OF THE INVENTION




Briefly, the present invention satisfies the need for a relatively fast, low-cost way to produce high-quality, high-penetration colorant patterns in porous material with at least slightly varying design in volume, by using flow guides in a vacuum environment to guide multiple colorants simultaneously across and into a porous material to create a pattern with high saturation of the porous material. The guides allow for variations in pattern when repeated with another porous material.




In accordance with the above, it is an object of the present invention to provide a way to create a pattern in porous material with colorant.




The present invention provides, in a first aspect, a method of creating a colorant pattern in porous material. The method comprises guiding a colorant in a vacuum environment across and into a porous material to create a colorant pattern therein.




The present invention provides, in a second aspect, a system for creating a colorant pattern in porous material. The system comprises a sealable vacuum chamber with at least one outlet for exiting of the atmosphere, and a template with at least one colorant flow guide for guiding a colorant across and into porous material and toward the at least one outlet when in contact with the template to create a colorant pattern in the porous material.




The present invention provides, in a third aspect, apparatus for creating a colorant pattern in porous material. The apparatus comprises a template with at least one colorant flow guide for guiding colorant along the flow guide when under vacuum.




The present invention provides, in a fourth aspect, a system for creating a colorant pattern in porous material. The system comprises a sealable vacuum chamber with at least one outlet, and at least one barrier gasket for creating at least two zones in the porous material. Each of the outlets is couplable to one of the zones.




The present invention provides, in a fifth aspect, a system for creating a colorant pattern in porous material. The system comprises a sealable vacuum chamber with at least one outlet, and at least one reservoir for providing colorant to the sealable vacuum chamber.




These, and other objects, features and advantages of this invention will become apparent from the following detailed description of the various aspects of the invention taken in conjunction with the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION





FIG. 1

depicts one example of a system


100


for creating a colorant pattern in porous material in accordance with the present invention. System


100


comprises a sealable vacuum chamber


102


including, for example, a base


104


, non-conforming sealing membrane


106


, conforming rubber blanket


107


, and gasket (i.e., perimeter seal)


108


. The sealable vacuum chamber can take many forms, such as, for example, a conventional vacuum table. System


100


also comprises a raised layer


110


providing vacuum flow channels (e.g., channel


112


) for exiting of colorant


114


as described below. The vacuum is created by vacuum pump


118


drawing atmosphere through at least one opening


116


, and when in operation, sealing membrane


106


and gasket


108


create the seal for the vacuum chamber.




In the present example, colorant


114


is situated above porous material


120


, which can be any porous material lending itself to colorant patterning, for example, fabric. Colorant


114


comprises, for example, any fluid or semi-fluid with dissolved or suspended color particles. As used herein, the term “colorant” comprises one color, a plurality of different colors, multiple shades of the same color, or any combination thereof. Of course, the colorant(s) chosen and the viscosity thereof will depend on the particular application, for example, the type of porous material being patterned and the desired patterning effect.




A template


122


comprises a plurality of openings (e.g., openings


124


and


126


) between which is a flow guide


128


for guiding colorant across and into porous material


120


. Template


122


can comprise any number of materials (e.g., plastic, metal, etc.), so long as it is stiff enough so as not to be conforming under vacuum. The template is easily modified and inexpensive, relative to screens, thereby providing a cost advantage. The flow guide(s) can be arranged in any design, for example, the heart design shown in

FIG. 1. A

flow guide can take any number of forms, so long as it serves the purpose of guiding colorant across the porous material. The flow guide also helps ensure that most or all of the colorant is absorbed by the porous material, in order to significantly reduce or eliminate puddling of colorant. Even slight differences in the porous material, air flow and/or the amount of colorant typically result in slight variations in successive patterns. Preferably, the flow guide also allows for at least slight variations in successive patterns created without altering the flow guide itself. Each of the example flow guides below allows for such variations.




For example, the flow guide can take the form of a channel within or on (see

FIG. 1

) the surface of template


122


. Where the channel is within the template, it simply acts as a canal between openings. As another example, the flow guide can take the form of a wire (e.g., wire


160


) on the template strung between two points, for example, between two openings (in this example, openings


162


and


164


). As another example, the flow guide can simply be one or more openings in the template (e.g., opening


166


). In conjunction with vacuum pump


118


, and depending on the location of at least some of the colorant other than directly above the opening(s), the opening(s) serve to pull the colorant across the porous material and toward the opening(s). As still another example, the flow guide can take the form of at least two barriers (e.g., barriers


130


and


132


) on the template, spaced apart such that a channel


134


is created between them. As yet a further example, the flow guide can take the form of at least one capillary, tube or other conduit on the template with a plurality of openings along a length thereof (see FIG.


3


and the description thereof). Of course, through-openings in the template are not necessary for the operation of system


100


. However, the openings assist in exhausting the colorant to the porous material, helping to significantly reduce or eliminate puddling of the colorant. Where no openings are included in the template (e.g., in a situation where the porous material being patterned is relatively small), the colorant would simply flow, when under vacuum, toward a nearest edge (e.g., edge


129


) to a channel in raised area


110


and toward opening


116


, for example. Of course, there will be a size limit when no openings in the template are used where edge flow will result in insufficient “drainage” causing, for example, puddling of colorant.





FIG. 1

also depicts one example of an excess colorant collector


150


in the form of a trough between conforming rubber blanket


107


and gasket


108


around base


104


. The trough is pitched such that colorant


156


therein will flow toward an outlet


152


, which is generally covered with a cap


154


until draining of the colorant is required. As shown, opening


116


to vacuum pump


118


is placed above the trough to reduce the likelihood of colorant entering the pump. Of course, a trough is merely one example of an excess colorant collector. As another example, described in detail with respect to

FIG. 2

, the excess colorant collector could take the form of a collection trap couplable to the vacuum outlet(s) (here, opening


116


).




It will be understood that non-conforming sealing membrane


106


is stiff enough so as to prevent conformal covering of that which lies beneath it when a vacuum is applied. In the past, conforming bladders providing even pressure, for example, were purposely used to help force ink through a stencil opening and through the fabric underneath. However, such conforming bladders may actually interfere with the flowing of colorant across the porous material in the present invention, due to the even pressure. Examples of preferred materials for membrane


106


include glass, metal and rigid plastic.





FIG. 2

depicts another example of a system


200


for creating a colorant pattern in porous material, in accordance with the present invention. A sealable vacuum chamber


210


comprises a non-conforming sealing membrane


212


and base


214


, similar to that in

FIG. 1

, except that the seal comprises a compressible seal


216


made of, for example, rubber around a periphery of the chamber. In addition, the base


214


must be non-conforming where both sides of the hollow template are used for pattern creation. As with the system of

FIG. 1

, a seal is achieved by the application of the vacuum, resulting in a pressure differential.




A hollow template


218


is shown placed inside a shirt


220


. There are openings on the top


222


and bottom


224


of the template (e.g., openings


226


and


236


on the top, with similar openings on the bottom). Each of the top and bottom of the template serves the same purpose as template


122


from

FIG. 1

, relative to each of a front side


230


and a back side


232


of shirt


220


, respectively. For example, a flow guide


234


can be placed between openings


226


and


236


. Where there are openings on both the top and bottom of the hollow template, the sides (e.g., side


238


) are preferably closed off. In such a situation, colorant from a colorant layer


240


, shown partially in

FIG. 2

for simplicity, would be pulled down by a vacuum through front


230


, along flow guide


234


and into opening


226


and/or


236


. Similarly, colorant from a bottom colorant layer


237


would be pulled up through the back side


232


, and along flow guides and through openings (not shown) on bottom


224


of the template similar to top


222


. It will be understood that colorant layers


237


and


240


need not be separate layers, but could be colorant placed directly on the surface of shirt


220


. In addition, patterns need not be created on both sides of the shirt. Flow guides on the outer face of both top


222


and bottom


224


allow pattern creation on both front side


230


and back side


232


of shirt


220


. For example, a logo could be created on the front side and reversed on the back side. The vacuum for system


200


is achieved with, for example, a vacuum pump


246


pulling atmosphere through opening


228


via conduit


244


. Unlike the system of

FIG. 1

, system


200


does not include a raised layer, due to the hollow nature of the template. Further, it will be understood that hollow template


218


need not lie horizontal in a vacuum chamber; it could also be situated vertically to enhance drainage of excess colorant.




One example of an excess colorant collector


250


is also depicted in

FIG. 2

in the form of a collection trap coupled to conduit


244


. A combination of colorant


252


and atmosphere enter the collection trap where the colorant falls by gravity to the bottom, while the atmosphere continues back out conduit


244


toward vacuum pump


246


.




An alternative to one or both of the colorant layers is to employ one or more colorant reservoirs, e.g., reservoirs


260


and


262


. Each reservoir includes colorant (e.g., colorant


263


), an opening in the top (e.g., opening


264


), and is coupled to an opening in the non-conforming sealing membrane


212


or base


214


, respectively, via a conduit. For example, reservoir


260


is coupled to opening


266


via tubing


268


. In addition, valves (e.g., valve


270


) are preferably included (here, on the conduits) to regulate the amount of colorant entering the chamber. Of course, any of the external or internal colorant delivery methods disclosed herein could be used with system


200


.





FIG. 3

depicts one example of a conduit-type flow guide mentioned above with respect to FIG.


1


. Shown in

FIG. 3

is porous material


300


atop a template


302


that can be used with sealable vacuum chamber


102


from FIG.


1


. At least one conduit (e.g., conduit


304


) lies on top of the porous material, and is connected to a colorant feed


306


. Colorant feed


306


, in turn, is connected to a colorant reservoir


308


. Colorant reservoir


308


can be flexible or rigid, open or sealed. Further, the reservoir can be valved to control dispensing. Each conduit comprises a plurality of openings along its length for the colorant


310


to exit, when under vacuum, onto porous material


300


and move thereacross and into toward a nearest opening (e.g., opening


312


shown in phantom) in the template. The vacuum provides the draw for colorant


310


, such that a separate pump is not typically necessary. The capillaries are sized to achieve the desired transport of colorant based on, for example, the viscosity thereof. In the embodiment shown in

FIG. 3

, the colorant feed and reservoir are external to the sealable vacuum chamber (not show in

FIG. 3

for simplicity). However, the colorant feed and reservoir could also be internal to the sealable vacuum chamber, for example, if the colorant reservoir took the form of a collapsible bladder.





FIG. 5

depicts one example of a collapsible bladder


500


. Bladder


500


can comprise any number of flexible, non-absorbent materials, for example, plastic or vinyl. Colorant


502


is held within bladder


500


until some force, either direct or indirect (here, the vacuum), in effect squeezes bladder


500


. Colorant


502


then flows out of bladder


500


into one or more capillaries or tubes


504


with a plurality of openings therein (e.g., opening


506


) through which colorant


502


exits onto and into porous material (not shown).





FIG. 4

depicts another embodiment of a system


400


in accordance with the present invention. System


400


comprises a cylindrical vacuum manifold


402


with at least one vacuum outlet


404


to a vacuum pump


405


through conduit


407


. A plurality of openings are shown in phantom (e.g., openings


406


and


408


) leading to vacuum outlet


404


through passages (not shown) internal to cylindrical vacuum manifold


402


. Manifold


402


is made of any number of stiff materials, for example, metal, plastic, etc. As with the other embodiments, colorant flow guides (e.g., flow guide


410


) are provided between the openings. Thus, the manifold serves the same functions as both base


104


and template


122


in the embodiment of FIG.


1


. Also, it will be understood that no openings need connect the flow guides. Colorant could simply move under vacuum across the guides and toward an opening (e.g., opening


412


) not covered by porous material


414


. The colorant flow guides can take all the forms mentioned previously with respect to FIG.


1


. Also shown in

FIG. 4

is a non-conforming sealing girdle


416


that can seal to vacuum manifold


402


by, for example, a compressible seal


418


similar to that described with respect to FIG.


2


. The non-conforming sealing girdle can be made of any number of stiff materials, for example, metal, plastic, etc. One example of an excess colorant collector


450


is shown in

FIG. 4

in the form of a collection trap, similar to that shown and described with respect to FIG.


2


. Excess colorant


452


is trapped in the collection trap, while atmosphere


454


passes through to vacuum pump


405


.





FIG. 6

depicts another example of the present invention. System


600


comprises a top non-conforming sealing membrane


602


and a corresponding bottom non-conforming sealing membrane


604


, together comprising a sealable vacuum chamber. Both membranes are similar to membrane


106


in

FIG. 1

, with the bottom membrane capable of serving the functions of both base


104


and template


122


in system


100


. Of course, the bottom membrane need not function as a template, and a separate template could be used, or some combination of both used as templates. In addition, the system of

FIG. 6

does not require a raised layer for flow channels, like raised layer


110


in the

FIG. 1

embodiment. The top membrane is sized identical to the bottom membrane. System


600


further comprises a perimeter barrier gasket


606


, similar to weather stripping, that prevents colorant (not shown for convenience) from potentially seeping out. The same type of gasket material is used below porous material


608


to create areas or zones where colorant can be guided separately from other zones. In this manner, the gasket material creating the zones is also a further example of a colorant flow guide. Of course, the gasket material could alternatively be placed on the porous material itself. This allows a greater degree of flexibility in design when necessary, as compared to the previous embodiments. The gasket material can be placed passively on the porous material, to be held in place by compression under vacuum, or it can be temporarily adhered to the porous material or template with a non-permanent adhesive, for example.




Zone


610


is shown in

FIG. 6

as having a star shape, and is coupled, via opening


612


in bottom non-conforming sealing membrane


604


and conduit


614


ultimately to vacuum pump


616


. Zone


610


is created with a barrier gasket


611


like gasket


606


. Similarly, each of the other zones


618


,


620


and


622


are coupled to the vacuum source by conduits


624


,


626


and


628


, respectively. Atmosphere through each of the conduits is independently controlled. For example, the atmosphere could be controlled by valves coupled to the conduits (e.g., valve


630


). The valves could be controlled manually, or even by computer. Alternatively, each zone could have its own vacuum source controlled independently. Although not shown in

FIG. 6

for simplicity, it will be understood that any of the colorant delivery methods herein could be used with system


600


.




One example of an excess colorant collector


650


is shown in

FIG. 6

, taking the form of a common collection trap for excess colorant


652


interposed between the various conduits (e.g., conduit


614


) mentioned above with respect to the various zones and another conduit


654


coupled to pump


616


. Of course, as another example, the conduits from the various zones could also be commonly coupled to the air pump and each have their own collection trap.




Since bottom non-conforming sealing membrane


604


also serves as the template in this embodiment, it will be understood that one or more flow guides as described above with respect to

FIG. 1

could be included so as to correspond to one or more zones. This would allow a pattern to be created in a particular zone. Where no flow guides are included for a given zone, the pattern could be allowed to be random, or colorant could saturate the entire zone (e.g., the star zone


610


in FIG.


6


), or the zone could have a complete absence of colorant. Where an absence of colorant is intended for a given zone, there need be no vacuum established for that zone.





FIG. 7

depicts still another example of a system


700


in accordance with the present invention. Like system


600


in

FIG. 6

, system


700


comprises a top non-conforming sealing membrane


702


and a corresponding bottom non-conforming sealing membrane


704


, together comprising a sealable vacuum chamber


705


. As with system


600


, bottom membrane


704


serves as both a base and template. Bottom membrane


704


includes one or more flow guides as described herein. Although not shown in

FIG. 7

, it will be understood that the gasket material described with respect to

FIG. 6

could also be used to create zones in porous material patterned with system


700


. Another alternative is to have no flow guides or gasket material. Of course, a single reservoir could be used, or less or more reservoirs than shown in FIG.


7


. Each reservoir includes an opening in the top (e.g., opening


740


in reservoir


712


), and is coupled to an opening in top membrane


702


via conduits. For example, reservoir


710


is coupled to opening


714


via tubing


716


. In addition, valves (e.g., valve


718


) are preferably included (here, on the conduits) to regulate the amount of colorant entering the sealable vacuum chamber.




In operation, a vacuum pump


720


is coupled to outlets


722


and


724


in bottom membrane


704


via conduits


726


and


728


, respectively. When activated, and when the reservoir valves are opened, the vacuum pump pulls atmosphere through the conduits to cause colorant


730


entering the vacuum chamber to move across and into porous material


732


toward outlets


722


and


724


, in accordance with the flow guides on bottom membrane


704


. Where the gasket material is used, zones would be created in porous material


732


, as described with FIG.


6


. Of course, a separate template could also be used, rather than the combination bottom membrane and template described with respect to FIG.


7


. System


700


further comprises an excess colorant collector


750


in the form of a common collection trap for colorant


752


coupled to vacuum pump


720


via conduit


754


, similar to that of FIG.


6


.





FIG. 8

depicts yet another example of a system


800


in accordance with the present invention. System


800


is similar to system


700


in

FIG. 7

, except that the open-atmosphere colorant reservoirs have been replaced with closed, syringe-type reservoirs


802


,


804


,


806


and


808


. The vacuum created in the system by vacuum pump


810


pulls the colorant in the reservoirs (e.g., colorant


812


in reservoir


806


) into the vacuum chamber


814


. As with system


700


, some type of valving (e.g., valve


816


) is preferably included to regulate the colorant entering the chamber.





FIG. 9

depicts another example of a system


900


in accordance with the present invention. System


900


is similar to system


700


in

FIG. 7

, with the addition of a controller


902


for controlling valves


904


,


906


,


908


and


910


. In addition, controller


902


(or a separate one) could control vacuum pump


912


and/or valves


916


and


918


. Controller


902


is preferably programmable to precisely control the release of colorant via the valves and the vacuum level via the vacuum pump and/or vacuum pump valves. In this way, complex colorant patterns can be created on porous material


914


, as well as recreated in separate applications. Of course, due to the inherent random nature of the method of application, subsequent applications on other porous materials will yield a certain level of uniqueness to each one. Controller


902


could instead take the form of a processor or computer. In one example, a computer system is used, and one or more predetermined designs could be shown on a display


920


, with one of the designs chosen by a user via conventional input means


922


(e.g., mouse and/or keyboard) for automated application to a porous material.





FIG. 10

depicts yet another example of a system


1000


in accordance with the present invention. System


1000


is similar to system


700


of

FIG. 7

, except that two of the colorant reservoirs have been replaced with additional conduits


1002


and


1004


coupled to the colorant collector


1006


and the vacuum pump


1008


. In addition, valves


1010


,


1012


,


1014


and


1016


are preferably included (in this example, on the conduits) to regulate the vacuum. Also, an optional flow guide


1018


is included on an underside


1020


of top membrane


1022


. In this example, flow guide


1018


takes the form of a channel between colorant inlet


1024


and outlet


1026


. Of course, as in the other embodiments herein, the flow guide can take many forms, the purpose of which is to guide colorant across the porous material. It will also be understood that more or less colorant inlets and outlets could be used, depending on the application.




The present invention, as described above, provides a relatively low-cost way to produce colorant patterns in porous material with at least slightly varying design in volume. In addition, the penetration of the colorant, at least in fabric, is such that the pattern produced is clear on both the front and back of the fabric with a single application.




While several aspects of the present invention have been described and depicted herein, alternative aspects may be effected by those skilled in the art to accomplish the same objectives. For example, the controller/processor control described with respect to

FIG. 9

can be used in other embodiments that include valves and/or vacuum pumps. As another example, the multiple zones of

FIG. 6

are applicable to other embodiments. Accordingly, it is intended by the appended claims to cover all such alternative aspects as fall within the true spirit and scope of the invention.
