Description

METHOD AND APPARATUS FOR PROCESSING A DISCONTINUOUS COATING ON A SUBSTRATE FIELD OF THE INVENTION This invention relates to the processing of continuous sheets or webs of materials such as nonwoven substrates. In particular, this invention relates to the processing of discontinuous coatings on continuous webs, for example paper of cellulose fibers.

BACKGROUND OF THE INVENTION Non-woven webs or sheets made of paper find widespread use in modern society. The paper webs are usually processed as tissues, towels and other disposable absorbent articles. Paper towels, for example, are commodity trade items that have been used for a long time to absorb liquid spills and to remove stains and / or grime from hard surfaces such as window glass, cabinet covers , tiles, accessories of porcelain and metal, walls and the like, and other surfaces such as carpets or furniture. Non woven paper web substrates having lotions and other coatings are well known in the art. Lotions are often used in conjunction with substrates to soften the substrate. Lotions can also be used to relieve the skin when the substrate is used, for example, as a facial tissue. Examples of substrates having lotion and which are useful in the facial tissue technique are found in U.S. Patent 4,426,418, issued January 17, 1984 to Coleman et al. and commonly assigned U.S. Patent 4,481,243, issued November 6, 1984 to Alien, the disclosure of the Alien patent is incorporated herein by reference. Products have been developed, such as wipes. Certain wipes have an important advantage over the closest prior art cleaning products for removing dirt, particularly from the perianal region. These wipes comprise a substrate (e.g., non-woven or tissue) treated with an emulsion of water in lipid. The lipid water emulsion provides water in a solid external wax phase that prevents the loss of water until they are used. When used, the wax phase is broken by pressure, releasing the internal aqueous phase. Therefore, these wipes release significant amounts of water during use for a comfortable and more effective cleaning. The wipes are particularly advantageous for cleaning, especially when provided in the form of wet cleaning wipes used to remove perianal dirt. An example of these towels and their preparation is found in commonly assigned World Patent Application WO 96/14835, published May 23, 1996, in the name of Mac ey et al, the disclosure of which is incorporated herein. as reference. The mechanism for transferring the water from the emulsion to the surface to be cleaned includes several steps. First, the water is released or extruded from the emulsion due to the pressure imparted by the user. The pressure breaks the external phase of the emulsion, releasing the internal aqueous phase. The water then saturates the substrate. During saturation, water penetrates the substrate in the Z direction. Excess water, which is water that exceeds the local absorptive capacity of the substrate, is then transferred from the wipe to the surface. A potential approach to the problem of providing sufficient amounts of water to saturate the substrate and transfer water to the surface is to have a continuous layer of emulsion on the substrate. A continuous layer of emulsion may contain a larger amount of water than a discontinuous layer of the emulsion. This potential approach has several disadvantages. First, a continuous thin layer of emulsion may not exceed the local capacity of the substrate. Second, the excessive lipid phase in the emulsion causes an accumulation and may not be well received by the user and contribute to processing difficulties. Third, if the amount of the emulsion becomes too large, it can hinder the breakdown of the emulsion and the release of water from it. This difficulty occurs due to a larger amount of the lipid phase that is present. While the amount of lipid phase increases, the release of the emulsion with respect to itself occurs, rather than the breakdown of the emulsion. Fourth, the ratio of surface area to volume is far from optimal. Finally, the cost of the wipe increases directly with the amount of emulsion provided. In addition to the aforementioned disadvantages, it has been found unexpectedly, that a continuous coating of the emulsion on the substrate does not provide the most effective cleaning, particularly when it is desired to clean human skin. Preferably, a discontinuous pattern of emulsion on the substrate provides a more effective cleaning mechanism. One of these discontinuous patterns of the emulsion on the substrate is set forth in the patent PJ.0S3 of the United States assigned in common form, with Serial No. 08 / 909,449 filed on August 11, 1997, which is incorporated herein by reference. During cleaning, the water is released from the emulsion to remove the dirt from the skin. The area of the skin wetted by water and from which the dirt is removed is then cleaned dry with the substrate regions free of the emulsion. Similar benefits occur when the wipe is used to clean other surfaces, such as window panes, cabinets, faucets, porcelain and metal fixtures, walls and the like, and other surfaces, such as carpets or furniture. A disadvantage of coating cellulosic or non-woven substrates with materials such as emulsions is that the emulsion, once applied to the substrate, can be cleaned or scraped by the processing elements of the downstream web. For example, the emulsion can be collected in rolls such as tension rolls, while the web is guided during processing. The emulsion collected in the tension rollers represents waste and the accumulation on the rollers must eventually be removed, resulting in undesired equipment downtime and production interruption.

In addition to producing inefficiencies in production and waste, the roller contact alters the emulsion in the substrate. This is particularly undesirable if the emulsion is required to maintain a certain thickness on the surface of the substrate. Similarly, if the emulsion is required to be maintained in a certain pattern on the substrate, any rubbing or abrasion due to contact with a guide roller in the process should be minimized. For example, if the coating also serves a decorative or aesthetic purpose, rubbing or removal of the coating is undesirable. In addition, if an aqueous lipid emulsion is applied to the web, rubbing or scrubbing during the processing of the web will likely cause a breakdown of the solid wax phase, resulting in premature release of water. While these disadvantages are particularly undesirable in the context of the application of emulsion in the wefts, it may be equally undesirable in the context of coatings in general, which include: liquid inks and dyes, extruded polymers, liquid adhesives and the like. similar. Once applied as a liquid coating to a web, these materials are susceptible to being cleaned or rubbed, or altered in any other way by further processing them by means of guide rollers, driven rollers, tension rollers, and the like. As a result, the original placement of material in the weave is altered, and an undesired accumulation of material is formed in the rollers downstream of the coating apparatus. Accordingly, it would be desirable to apply a coating to a weft substrate and further process the weft in a manner that prevents the coating from rupturing. Additionally, it would be desirable to apply a coating to a weft substrate in certain patterns without the coating or pattern breaking during the subsequent processing of the substrate. In addition, it would be desirable to apply an emulsion to a cellulosic web substrate in a predetermined pattern or amount, without the predetermined pattern or amount being altered during subsequent processing of the web.

SOMARIQ OF THE INVENTION The present invention comprises an apparatus for producing a coated paper web in a selective manner. The apparatus comprises a coating means for applying a coating to a paper web in a plurality of coated regions, the coated regions being spaced apart, in parallel relation to a plurality of uncoated regions. The present invention further comprises supporting means for supporting the web after coating, the support means comprise a plurality of support members, each of the support members is in register with an uncoated region. In a preferred embodiment, the coating of a beneficial emulsion is applied in selected regions, by extrusion. Also disclosed is a method for forming a coated paper web without producing coating material accumulation on the tension rollers. The method comprises the steps of: (a) coating a web in a plurality of coated regions, the coated regions are in separate relation in parallel with uncoated regions; (b) providing support members, each of the support members is aligned in register with an uncoated region; and (c) guiding the coated web in contact with the support members such that each support member is in register with an uncoated region of the web.

DETAILED DESCRIPTION OF THE INVENTION While the following disclosure describes the method and apparatus of the present invention, primarily in relation to cellulosic substrates that are coated with a beneficial emulsion, it will be understood that neither the method nor the apparatus of the present invention are limited to the processing of paper webs. The method and apparatus of the present invention can be useful for the processing of any substrate and coating. For example, the coating can be made by printing, extruding or, otherwise, P1063 partially or completely coating a substrate with ink, colorants, emulsions, adhesives or other liquid or powder coatings. The substrates can include any materials that can be processed as wefts, including paper, cloth, textiles, polymeric films, nonwovens, or other laminated materials. As used herein, "substrate" refers to the material and, in particular, to the weft material processed by the method and apparatus of the present invention. For example, substrates suitable for use in the present invention include cellulose paper, fabrics, textiles, polymeric films, nonwovens, or other laminated materials, including rolled metal. The terms "substrate" and "frame" are used interchangeably here. As used herein, the terms "overlay" or "overlay", such as verbs, include covering, overcoating, finishing, or in any way, applying a layer of material to a substrate. For example, "coating" includes printing, spraying, extruding and laminating materials onto a substrate in a controlled, predetermined manner. Suitable materials include liquid materials, as well as powdered materials that can be applied as a coating to a large extent, in the same way as liquid materials. As used herein, the terms "coating" or "coating", as nouns, refer to the material on the substrate, after the process of applying the material to the substrate. The coating, in accordance with the present invention, is generally applied in a discontinuous pattern. In the form in which it is used herein, a "discontinuous pattern" of the coating is a pattern having intermediate coating regions of the regions of the substrate on which the coating is placed. For example, extruding separate pearls of an emulsion onto a substrate would produce a discontinuous pattern while printing a regular pattern of separate adhesive spots on a nonwoven material. As used herein, "selectively coated" refers to a web having a coating selectively applied to predetermined regions of a substrate. In accordance with the present invention, the predetermined coated regions are, in general, separated in parallel relationship with uncoated regions which are in register with the weft support means, as fully described below. For example, a paper web having a discontinuous pattern of substantially parallel strips or strips separated by strips or bands of uncoated regions is selectively coated. Moreover, the strips or bands that form regions P1063 coated in a selectively coated weft can themselves be applied in a discontinuous pattern. For example, a discontinuous pattern of separate adhesive spots can collectively form a coating strip or band. As used herein, the term "wipe" refers to a substrate, preferably coated with performance-enhancing materials, used for cleaning. For example, the wipe can be used as a facial tissue, tissue for bath, paper towel, a baby wipe, an adult wipe, a hard surface cleaner, etc. The use to which the wipe is intended does not, however, limit the final products. As mentioned in the above, the method and apparatus of the present invention can be practiced in a wide variety of applications and end uses. For purposes of illustrating its features and advantages, the present invention is described in detail below, in relation to a preferred embodiment of a cellulose paper substrate selectively coated with a beneficial emulsion.

The Apparatus _ Figure 1 shows in schematic form, a P1063 typical configuration of an apparatus 1 of the present invention. In general, the apparatus 1 comprises coating means 2, for example the printing roller 6, and support means 4, for example the tension roller 16, in operative relation. As used herein, "operative relation" means that during the processing of the paper web the coating means 2 and the support means 4 are configured in such a way that the coating means 2 selectively covers a paper web substrate 10. and the support means 4 subsequently supports the paper web with the support members 18 in register with uncoated portions of the selectively coated web. The coating 11 can be applied to a substrate 10 and placed thereon, by any suitable means permitting selective areas of application, for example gravure printing, flexographic printing, screen printing, spraying and extrusion. Preferably, the coating 11 is an emulsion (as described more fully below, with reference to Figures 10-12), applied to the substrate by means of a gravure printing process. More preferably, the emulsion is extruded as a series of continuous beads shaped into cylinders. A continuous cylindrical shape is preferred for the P1063 emulsion because this shaping reduces the ratio of the surface area to the volume of the emulsion. In a preferred embodiment, the coating means comprises a gravure printing roller 20, as shown in Figure 2, and the support means comprises a stepped roller, such as the tension roller 16, as shown in Figure 3. As used herein, "stepped" means that the tension roller is formed such that the roller has at least two diameters, with a plurality of steps 14 of larger diameter that are in separate relation, as shown in the Figure 3. The larger diameter steps 14 are preferably of the same diameter, so as to serve as support members 18 for a relatively flat paper web substrate 10 during processing. In a preferred embodiment, and as used herein, the rolls are typically tension rolls or guide rolls. The present invention is not limited to tension rollers, however; the rollers may be driven to aid in the transport of the weft during processing, without departing from the scope of the present invention. The gravure printing roller 20 functions as part of a gravure printing apparatus (not shown). The gravure roll 20 P1063 may be configured to print various patterns, including a regular pattern of generally square "points" 22, as shown in Figure 2. In general, for any pattern provided, the gravure printing roller is designed to selectively coat the web 10 such that the unprinted portions 24 correspond to uncoated regions 34 (as discussed below with reference to Figures 4 and 5) of a selectively coated web, processed by the method and apparatus of the present invention. Similarly, the printing portions 26 correspond to coated regions 36 of a selectively coated web processed by the method and apparatus of the present invention. As shown by the regularly separated points 22, in Figure 2, the coated regions 36 may comprise a discontinuous pattern of material, which collectively forms a strip or band of coated region 36. The steps 14 of the tension roller 16 are in relation to each other. separate such that they serve as support members 18, by contacting the record frame with the uncoated regions 34 of the selectively coated web. The weft being in contact only in uncoated regions, the support members 18 do not generate a coating build-up, and the P10S3 coating in the coated regions is not disturbed. Therefore, the coating remains in the weft in the specific pattern and in the desired amount, and the support means 4, for example tension roll 16, remains free of coating material that would otherwise be deposited on it. the roller during the processing of the frame. The width and spacing of the coated regions 36 (or conversely, the uncoated regions 34) of the weft substrate 10 can be adjusted as desired, with the mere requirement that during the subsequent support by the support means 4, the members of support 18 are in contact with the web in uncoated regions 34. It is not necessary, however, that there be a support member associated with each uncoated region. Depending on the width of the coated and uncoated regions, it may be desirable to have more than one support member in some uncoated regions, or, conversely, to have some uncoated regions not supported. For example, it may be desirable to have a minimum number of support members needed to accommodate the weft support, with the ability to vary the number of coated / uncoated regions between the weft support members. In this way, the quantity and placement of material on the plot can be changed by requirements of different products without necessarily having to change, correspondingly, the means of support. Figure 3 shows the preferred embodiment for the support means 4 as the stepped tension roller 16. In the preferred embodiment, the stepped tension roller 16 serves as a roll support member, with steps 14, preferably making non-slidable contact with the weft substrate 10, particularly in the uncoated regions of a selectively coated substrate. In other words, it is generally undesirable to have sliding, abrasive or rubbing contact between the tension roller and a selectively coated cellulosic web. By using the roller support, it is reduced and, preferably, there is no relative movement between the circumferential surface of the steps 14 and the weft substrate 10. If necessary, the circumferential surface of the steps 14 can be treated with a non-sticky, high coefficient of friction coating to ensure rolling contact with the weft substrate 10. As mentioned above, a tension roller is a preferred for the support means 4. However, the support means 4 may comprise a driven roller as necessary to process the weft selectively P10S3 coated. As shown in Figure 3, the steps 14 can be described as discs in contact with the weft, and can be formed integrally with the tension roller 16 by suitably machining a length of steel round or tube. For example, in a preferred embodiment, an aluminum tube length having an outer diameter approximately equal to the diameter of the steps 14, as with a lathe, is machined to remove material between the steps 14. At least enough is removed material to allow the applied coating 11 to pass between the steps without contacting the roller 16. Once completed, the steps 14 comprise discs in contact with the weft that are integral with the tension roller, ie they can not be moved, permanently placed on the roller. Alternatively, the discs in contact with the weft can be formed as circular, annular disc-shaped members and be fixed in a suitably dimensioned roller shaft. For example, the annular members may snap into the arrow, or be adjusted with positioning screw means to be fixed in a stationary position on a tension roller arrow. Another alternative to provide a bearing support for the coated weft substrate 10 P1063 is selectively shown in partial section view in Figure 4. As shown, the bearing support can be provided by placing discrete rolling members, eg, rollers 42, on a non-rotating arrow 40. The bearings 44 on the rollers 42 ensure free and smooth rotation of the rollers 42. The bearings 44 can be press-fitted onto the arrow 40, or alternatively fixed by any means known in the art, including the use of set screws. The rollers 42 can be coated with a non-adhesive coating material 15 and with high coefficient of friction, as necessary for the bearing contact. As with the tension roller 16, the rollers 42 are axially spaced and placed to register with uncoated regions 34 of selectively coated weft substrate 11. The arrow and roller embodiment shown in Figure 4 may be particularly desirable for use as a Mount Hope roller in a screen processing apparatus. A Mount Hope roller is a weft scattering device that creates a tension in the transverse direction on the weft to pull loose wrinkles. These rollers are known in the weft processing technique and generally comprise a curved arrow that produces an upwardly facing arc that forces P1063 to the frame to be prepared and extended while passing through the rollers placed on the arrow. The roller of the present invention can be adapted to be a Mount Hope roller by the selective placement of rollers in a curved arrow. Another means of support, both rolling and non-rolling, can be used with good results, depending on the substrate material. For example, for some substrates, such as polymer films, a non-bearing support means may be suitable. For example, instead of employing a tension roller or discrete rollers in an arrow, the support means may simply comprise rigid or spring loaded fingers or tabs (not shown) that make smooth contact with the moving weft substrate in sliding contact. The only requirement for the purposes of the present invention is that the sliding contact can be made in register with uncoated regions of the selectively coated weft substrate. Additionally, variations in the bearing support means are contemplated. For example, the discrete rolling members may be positioned at the end of adjustable arms on a stationary arrow as shown in Figures 5 and 6. The non-rotating arrow 50, Stationary P1053 serves as a mounting surface for a plurality of adjustable roller support arms 52 in a rotatable manner. In one embodiment, the roller support arms 52 can be mounted in an adjustable manner by tightening a fixing member 53 for engagement by attachment means 56. In this form, the roller support arms 52 can be adjusted both axially along the length of the support. arrow 50 as rotating around the arrow 50, as shown in Figure 5. The discrete rollers 54 can be mounted to the support arms 52. To accommodate the various coating patterns, several roller support arms 52 can be rotated in position in contact with the frame, or out of the position in contact with the frame, shown in Figures 5 and 6 as 52 '. For certain substrates, particularly very flexible, elastic or low strength substrates, the rolling support means 4 may be altered to provide air support for the interframe support members 18. A preferred roll for this purpose is illustrated in Figure 7. As shown in Figure 7, some weft substrates may be prone to buckling or sagging between the support members. Therefore, a porous, air-permeable roller 17 having an accessory 19 for P1063 air supply. The air pressure enters through the accessory 19 for axially mounted air supply and exits through the air permeable roller 17 as an air pressure layer around the circumference of the roller between the support members 18. As illustrated in Figure 8, the air layer 21,21 'dampens the weft 10 in the areas between the support members 18 and prevents contact between the roller 17 and the weft 10, or the coating 11. A preferred air-permeable roller 17 is a Mott Air Film Roll designed specifically to guide a weft on an air cushion during transport. The preferred air-permeable roller is formed of sintered metal to still allow the flow of air through the roller. The roller may be permeable to air around the entire circumference, but it is preferred to "mask" a portion of the non-active surface area of the roller. By masking the non-active portions of the roller, the compressed air is released only through the roller in the regions close to the weft being transported. The non-active surface area includes the areas that are not in the vicinity of the frame that is being transported. For example, in Figure 8, the air cushion layer 21 is shown in proximity to the weft 11 and is, therefore, in an active area. The air cushion layer 21 'is not in the vicinity of the weft 11 and is, therefore, in a non-active area. The actual range of the active and non-active areas will depend on the wrapping angle of the weft on the roller. The method for masking the air permeable roller 17, if used, depends on the configuration of the arrow and the rolling support means 14. If the support members 18 are mounted (eg, by snap fit) on the arrow 17 so that the arrow and the support members rotate as a unit, a non-rotating inner mask is preferred. If the support members 18 are mounted rotatably (for example, on roller bearings) so that the support members 18 rotate on a non-rotating arrow 17. Other masking means can be used, including painting the mask areas with a removable paint or grinding the porous metal so that the pores close. As shown in Figures 9 and 10, the coating can be applied in virtually any pattern, including decorative patterns. The only limitation to pattern selection is that the pattern is delimited within a band-formed region, shown by interrupted lines 38. The printed pattern bands then, inherently, leave the bands or strips of uncoated regions, shown in FIGS. and 6, P10G3 also delimited by interrupted lines 38. Although not necessarily in strict form, for the purposes of the present invention, it is highly preferred, that the bands of uncoated regions remain, in separate relation generally parallel in the direction of machining of the plot substrate. The machine direction is parallel to the longitudinal axis L, as shown in Figure 9, and perpendicular to the transverse direction T. As shown in Figure 9, the coating 11, which is preferably a beneficial emulsion 12, can be applied in a non-linear manner, i.e. by varying the width or placement in the transverse direction within the limits of the coated region 36. The only limitation for the transverse placement of the coating 11 is that a minimum width of the uncoated region 34 should be retained, each region 34 not coated in parallel, generally linear, relationship with other uncoated regions 34. The minimum width of the uncoated region 34 depends on the width of the support members 18 and must be at least equal to or greater than this width. As shown in Figure 10, the coating 11 can be applied in visually attractive patterns that provide the substrate with an appearance P10 < J3 beneficial aesthetic. For example, an emulsion 12 in the form of flowers can be applied in a repeating pattern to form a discontinuous coating band that forms the coated region 36. Each coated region 36 of repeated patterns is separated by uncoated regions 34, as shown by interrupted lines 38. Virtually unlimited variations of discontinuous patterns are possible by means of the method and apparatus of the present invention. For example, if the gravure roll of Figure 2 is employed, the pattern produced on the substrate would be bands or strips of coated regions comprising a discontinuous coating of separate square "dots". Although the stitches are spaced apart, thereby producing a discontinuous coating, together, they form strips or bands of coated regions 36. In a more preferred embodiment, the coating 11, preferably an emulsion 12, is applied by extrusion, as shown in Figure 11. While the weft substrate 10 is provided from a supply roll, it is selectively coated by means of a plurality of separate extrusion heads 60. As illustrated in Figure 11, the support means 4 may include supports for forces other than gravity. For example, as shown, while P1063 processes the selectively coated web, it may be necessary to guide it in a directional manner, requiring support means, for example, a tension roller support 16, typical of those shown in Figure 3. At any point in the processing of the web selectively coated in that the web should change direction, as shown in Figure 11, the support means 4 of the present invention may be necessary. Extrusion of the preferred emulsion in a selectively coated pattern is preferably achieved by the use of standard processing equipment configured by extrusion of hot melt adhesives. Referring again to Figures 3, 9-10, the selectively coated web processed by the method and apparatus of the present invention preferably comprises a substrate 10 and a coating 11 selectively positioned therein. The substrate 10 is preferably cellulosic, in particular a tissue, a non-woven material, a foam or any combination thereof. The coating 11 is preferably a beneficial emulsion 12, for example a lotion. Preferred substrates 10, emulsions 12 and standards are now described below with respect to the preferred wipe 30, as shown in Figure 12, produced from a preferred weft substrate 10.

P1063 A Preferred Substrate Suitable cellulose substrates 10 are described in U.S. Patent 5,245,025 issued September 14, 1993 to Trokhan et al. 5,503,715, granted on April 2, 1996 to Trokhan et al. 5,534,326 issued on July 9, 1996 to Trokhan et al. 4,637,859 granted on January 20, 1987 to Trokhan 4,514,345 granted on April 30, 1985 to Johnson et al. 4,529,480 granted on July 16, 1985 to Trokhan 5,328,565, granted on July 12, 1994 to Rasch et al. 4,191,609 granted on March 4, 1980 to Trokhan 4,300,981 granted on November 17, 1981 to Carstens 4,513,051 granted on April 23, 1985 to Lavash 4,637,859 granted on January 20, 1987 to Trokhan 5,143,776 granted on September 1, 1992 to Givens 5,637,194 issued on June 10, 1997 to Ampulski et al .; 5,609,725 granted on March 11, 1997 to Phan and 5,628,876 granted on May 13, 1997 to Ayers et al., Whose expositions are incorporated herein by reference. A suitable tissue substrate 10 has a basis weight of approximately 7 to 25 pounds per 3,000 square feet per sheet, preferably approximately 8 to 10 pounds per 3,000 square feet per sheet and more preferably approximately 8-1 / 2 inches. pounds per 3,000 feet P1063 squares per sheet for toilet paper applications, and approximately 18 to 22 pounds per 3,000 square feet per sheet for hard surface cleaning applications. A substrate 10 of multiple basis weights is possible for the claimed invention. A substrate 10 of multiple basis weights has high and low base weight regions juxtaposed together and, optionally, intermediate weight basis regions. Regions of high basis weight provide resistance. The low basis weight regions provide transfer of water released from the emulsion to the surface. In a degenerate case, the base weight regions may be openings, to increase the transfer of water to the surface. If the substrate 10 of multiple basis weights is used, the macro basis weight of the substrate 10 is considered, averaging both the high and low basis weight regions or the high, intermediate and low basis weight regions. If a substrate 10 of multiple basis weights is desired, such a substrate 10 may be made in accordance with commonly assigned U.S. Patent Applications No. 5,277,761 issued January 11, 1994 to Phan et al .; 5,443,691 issued on August 22, 1995 to Phan et al. and 5,614,061 granted on March 25, 1997 to Phan et al, whose expositions are incorporated herein by reference. If a multi-substrate 10 is desired P1063 base weights having radially oriented fibers, this substrate 10 can be made in accordance with commonly assigned United States Patents, No. 5,245,025 issued September 14, 1993 to Trokhan et al .; 5,503,715 issued on April 2, 1996 to Trokhan et al .; 5,527,428 issued on June 18, 1996 to Trokhan et al. or 5,534,326 issued July 9, 1996 to Trokhan et al., the disclosures of these patents are incorporated herein by reference. If one wishes to use a nonwoven or more durable substrate 10 for a wipe 30, this substrate 10 can be made in accordance with commonly owned U.S. Patent Nos. 4,097,965 issued July 4, 1978 to Gotchel et al .; 4,130,915 issued December 26, 1978 to Gotchel et al .; 4,296,161 issued October 20, 1981 to Kaiser et al. and 4,682,942 issued July 28, 1987 to Gotchel et al., whose expositions are incorporated herein by reference.

A Preferred Emulsion Coating The preferred coating 11 is a beneficial emulsion 12. The preferred emulsion 12 comprises: (1) a solidified continuous lipid phase; (2) an emulsifier which forms the emulsion 12 when the lipid phase is fluid; and (3) an internal polar phase dispersed in the lipid phase.

P1063 This emulsion 12 breaks when subjected to low shear stress during use, for example cleaning of the skin or other surface, to release the internal polar phase. 1. External Lipid Phase The solidified continuous lipid phase provides the essential stabilizing structure for the internal high phase reverse emulsions 12 of the present invention. In particular, this continuous lipid phase is what preserves the dispersed internal phase of being released prematurely before the use of the article, such as during storage. The continuous lipid phase may comprise from about 2 to about 60% of the emulsion 12 of the present invention. Preferably, this continuous lipid phase will comprise from about 5 to about 30% of the emulsion 12. More preferably, this lipid phase will comprise from about 6 to about 15% of the emulsion 12. The largest constituent of this continuous lipid phase is a Waxy lipid material. This lipid material is characterized by a melting point of about 30 ° C or higher, i.e., which is solid at ambient temperatures. Preferably, the lipid material has a melting point of about 50 ° C or higher. Typically, the lipid material has a point P1063 melting in the range of about 40 ° to about 80 ° C, more typically in the range of about 50 ° to about 70 ° C. Although this waxy lipid material is solid at ambient temperatures, it also needs to be fluid or plastic at the temperatures at which the inverse emulsion 12 of high internal phase content is applied to the carrier. Moreover, even when the lipid material is fluid or plastic at those temperatures at which the emulsion 12 is applied to the carrier substrate 10, it should still be desirable to be stable in some way (i.e. coalescence of micro droplet emulsion 12) for periods of time. prolonged times at elevated temperatures (e.g., at about 50 ° C higher) that are normally encountered during storage and distribution of the articles of the present invention. This lipid material also needs to be sufficiently brittle under the shear conditions of use of the article in such a way that it ruptures and releases the dispersed internal polar phase. These lipid materials should also desirably provide a good feeling to the skin when used in personal care products, such as for wipes 30 for wet appearance cleaning and tissue paper used in perianal cleaning.

P10S3 Waxy lipid materials suitable for use in the high internal phase inverse emulsion 12 of the present invention include natural and synthetic waxes as well as other oil soluble materials having a waxy consistency. As used herein, the term "waxes" refers to compounds or organic mixtures which are generally insoluble in water and which tend to exist as crystalline or microcrystalline or amorphous solids at room temperatures (eg, at about 25 ° C). Suitable waxes include various types of hydrocarbons, as well as esters of certain fatty acids and fatty alcohols. They can be derived from natural sources (ie, animals, plants or minerals) or they can be synthesized. Mixtures of these various waxes can also be used. Some representative animal and vegetable waxes that can be used in the present invention include beeswax, carnauba, whale white, lanolin, shellac wax, candelilla and the like. Particularly preferred animal and vegetable waxes are beeswax, lanolin and candelilla. Waxes representative of mineral sources that can be used in the present invention include petroleum-based waxes, such as paraffin, petrolatum and microcrystalline wax and ceresin or fossil waxes such as white wax, yellow wax, white wax and the like .

Representative synthetic waxes that can be used in the present invention include ethylenic polymers such as polyethylene wax, chlorinated naphthalenes such as "Halowax", hydrocarbon type waxes made by Fischer-Tropsch synthesis, and the like. Particularly preferred synthetic waxes are polyethylene waxes. In addition to the waxy lipid material, the continuous lipid phase may include minor amounts of other lipophilic or lipid miscible materials. These other lipid / lipophilic miscible materials are usually included for the purpose of stabilizing the emulsion 12 to minimize the loss of the internal polar phase or to improve the aesthetic feel of the emulsion 12 on the skin. Suitable materials of this type that may be present in the continuous lipid phase include hot melt adhesives such as Findley 193-336 resin, long chain alcohols such as for example cetyl alcohol, stearyl alcohol and cetaryl alcohol; water insoluble soaps such as aluminum stearate, silicone polymers such as polydimethylsiloxanes, polymers P1063 silicone hydrophobically modified as trimethicone phenyl, and the like. Other suitable lipid / lipophilic miscible materials include polyol polyesters. By "polyol polyester" is meant a polyol having at least 4 ester groups. By "polyol" is meant a polyhydric alcohol containing at least 4, preferably from 4 to 12, and more preferably from 6 to 8 hydroxyl groups. The polyols include monosaccharides, disaccharides and trisaccharides, sugar alcohols and other sugar derivatives (e.g., alkyl glycosides), polyglycerols (e.g., diglycerol and triglycerol), pentaerythritol, and polyvinyl alcohols. Preferred polyols include xylose, arabinose, ribose, xylitol, erythritol, glucose, methyl glucoside, mannose, galactose, fructose, sorbitol, maltose, lactose, sucrose, raffinose and maltotriose.

By "liquid polyol polyester" is meant a polyol polyester from the groups described hereinbefore, which have a fluid consistency at or below 37 ° C. By "solid polyol polyester" is meant a polyol polyester from the groups described hereinbefore, which have a plastic or solid consistency at or above 37 ° C. The liquid polyol polyesters and the solid polyol polyesters can be used successfully as emollients and immobilizing agents, respectively, in emulsions 12 of the present invention. In some cases, the solid polyol polyesters may also provide some emollient functionality. 2. Internal Polar Phase Typically, the main component of the high internal phase inverse emulsions 12 of the present invention is the internal polar phase dispersed. In preferred embodiments, the polar phase will contain a significant percentage of water, preferably of at least about 60% by weight of emulsion 12, more preferably, at least about 75% by weight, even more preferably, at least 90% by weight. The internal polar phase can provide a P1063 number of different benefits when it is released. For example, in wet cleaning wipes 30 for perianal cleaning where the internal polar phase is water, it is this released water that provides the main cleaning action for these wipes 30. In a preferred embodiment of the present invention, the Internal polar phase (which preferably comprises water as a major constituent) is a disinfecting polar phase comprising an antimicrobial compound, preferably an essential oil or an active thereof, and a bleach, preferably a peroxygen bleach. Disinfecting wipes 30 comprising an internal disinfecting polar phase of this type provide effective disinfecting performance on a surface while being safe for the treated surface.

Disinfecting wipes 30 in accordance with the invention are suitable for disinfecting various surfaces, including animated surfaces (e.g., human skin) as well as inanimate surfaces, including hard surfaces. Regardless of its composition, the internal polar phase will preferably comprise from about 67 to about 92% of the emulsion 12. More preferably, the internal polar phase will comprise from about 82 to about 91% of the 12 emulsion. internal polar comprises water as its main component, the internal phase can comprise dispersible or water-soluble materials that do not adversely affect the stability of the inverse emulsion of high internal phase content. One of these materials that is typically included in the internal aqueous phase is a water soluble electrolyte. The dissolved electrolyte minimizes the tendency of materials present in the lipid phase to also dissolve in the aqueous phase. Any electrolyte capable of imparting ionic resistance to the aqueous phase can be used. The electrolytes Suitable P1053 include the water soluble mono, di or trivalent organic salts such as the water-soluble halides, for example, chlorides, nitrates and sulfates of alkali metals and alkaline earth metals. Examples of these electrolytes include sodium chloride, calcium chloride, sodium sulfate, magnesium sulfate and sodium bicarbonate. The electrolyte will normally be included in a concentration in the range of about 1 to about 20% of the internal aqueous phase. Other dispersible or water soluble materials that may be present in the inner polar phase include thickeners and viscosity modifiers. Suitable thickeners and viscosity modifiers include polyacrylic and hydrophobically modified polyacrylic resins such as Carbopol and Pemulen, starches such as: corn starch, potato starch, tapioca, gums such as guar gum, gum arabic, cellulose ethers, for example: hydroxypropyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose and the like. These thickeners and viscosity modifiers will normally be included in a concentration in the range of about 0.05 to about 0.5% of the internal phase. Again, when water is a major constituent of the internal polar phase, the materials P1063 dispersible or water soluble which may be present in the internal phase include polycationic polymers to provide steric stabilization at the interface of the polar phase-lipid phase and nonionic polymers that also stabilize the emulsion 12. Suitable polycationic polymers include: Retention 201 , Kymene® 557H and Acco 711. Suitable non-ionic polymers include polyethylene glycols (PEG) such as Carbowax. These polycationic and nonionic polymers will normally be included in a concentration in the range of about 0.1 to about 1.0% of the polar phase. 3. Emulsifier Another key component of the inverse emulsion 12 of high internal phase content of the present invention is an emulsifier. In the emulsions 12 of the present invention, the emulsifier is included in an effective amount. What constitutes an "effective amount" will depend on a variety of factors including the respective amounts of the internal polar phase and lipid components, the type of emulsifier used, the level of impurities present in the emulsifier and the like factors. Typically, the emulsifier comprises from about 1 to about 10% of the P1053 emulsion 12. Preferably, the emulsifier will comprise from about 3 to about 6% of the emulsion 12. More preferably, the emulsifier will comprise from about 4 to about 5% of the emulsion 12. While the "emulsifier" is used in In order to describe these components, more than one emulsifier can be used when the emulsion 12 is formed. In fact, as discussed below, it may be desired to use both a primary and a secondary emulsifier when certain materials are used. Although it is not intended to limit the scope of the invention, when using two emulsifiers, it is preferred that the primary emulsifier comprises from about 1 to about 7%, more preferably from about 2 to about 5%, most preferably about 2. to about 4% by weight of the emulsion 12; and that the secondary emulsifier comprises from about 0.5 to about 3%, more preferably from about 0.75 to about 2%, more preferably from about 0.75 to about 1.5% by weight of the emulsion 12. The emulsifier needs to be practically soluble in lipid or miscible with the lipid phase materials, especially at the temperatures at which the material melts. It must also have a relatively low HLB value. Suitable emulsifiers for use in the present invention have HLB values typically in the range of about 2 to about 5 and may include mixtures of different emulsifiers. Preferably, these emulsifiers will have HLB values in the range of about 2.5 to about 3.5. Preferred emulsifiers for use in the present invention include silicone polymer emulsifiers such as alkyl dimethicone copolyols example (eg laurylmethicone copolyol Q2-5200 Dow Corning). Emulsifiers are described in detail in copending US Serial No. 08 / 767.120 filed 14 January 1997 L Mackey (Case 5653C), which is incorporated herein by reference. Other suitable emulsifiers are described in copending U.S. Patent Application No. 08 / 336,456 filed November 9, 1994 by L. Mackey et al. (Case 5478), and U.S. Patent Application No. 08 / 761,097 filed December 5, 1996 by L. Mackey et al. (Case 5478R), both incorporated herein by reference. The emulsifiers described herein include certain sorbitan esters, preferably sorbitan esters of C?-C22, saturated, unsaturated or chain fatty acids.

P O63 branched. Due to the way in which they are typically processed, these sorbitan esters usually comprise mixtures of mono, di, tri, etc. esteres. Representative examples of suitable sorbitan esters include: sorbitan monooleate (e.g., SPAN® 80), sorbitan sesquioleate (e.g., Arlacel® 83), sorbitan monoisostearate (e.g., CRILL® 6 manufactured by Croda), stearates sorbitan (for example, SPAN® 60), sorbitan triooleate (for example, SPAN® 85), sorbitan sorbate (for example SPAN® 65) and sorbitan dipalmitatos (for example, SPAN® 40). The laurylmethicone copolyol is a particularly preferred emulsifier for use in the present invention. Other suitable emulsifiers described herein include certain glyceryl monoesters, preferably glyceryl monoesters of the saturated, unsaturated or branched chain fatty acids C1S-C22, such as for example: glyceryl monostearate, glyceryl monopalmitate and glyceryl monobehenate; certain esters of sucrose fatty acids, preferably sucrose esters of the saturated, unsaturated and branched C C 2 -C22 fatty acids, such as sucrose trilaurate and sucrose distearate (eg, Crodesta® FIO), and certain polyglycerol esters of saturated, unsaturated or branched C6-C22 fatty acids, such as diglycerol monooleate and tetraglycerol monooleate. In addition to these primary emulsifiers, co-emulsifiers can be used to provide additional stability to the lipid emulsion 12 in water. Suitable coemulsifiers include phosphatidyl cholines and compositions containing phosphatidyl choline, for example lecithins; long chain C? 6--C22 gra fatty acid salts such as sodium stearate, long chain C dial 6--C22 dial dialiphatics, short chain C dial -C 4 dialiphatic quaternary ammonium salts such as dimethyl dimethyl ammonium chloride and dimethyl methylisulfate ammonium from disebo; long-chain dialkyl (alkenoyl) -2-hydroxyethyl) C-6-C2, dialiphatic short-chain C?-C4 quaternary ammonium salts such as dialkyl-2-hydroxyethyl dimethyl ammonium chloride, the dialiphatic imidazolinium ammonium C salts; 6-C22 long chain such as, for example, methylisulfate imidazolinium of methyl-1-tallowamido ethyl-2-tallow and methylisulfate imidazolinium of methyl-1-oleyl amido ethyl-2-oleyl; short chain C1-C4 dialiphatic, long chain C6- C22 monoaliphatic benzyl quaternary ammonium salts such as dimethyl stearyl benzyl ammonium chloride and synthetic phospholipids such as stearamidopropyl PG-dimonium chloride (PTS Phospholipid from Mona Industries). Interfacial tension modifiers such as cetyl and stearyl alcohol can also be included for more compact packaging.

P1063 Other emulsifiers useful in making the articles of the present invention include the high viscosity emulsifiers described in copending United States Patent Application Serial No. 08 / 759,547, filed December 5, 1996 by L. Mackey and B. Hird, which is incorporated here as a reference. These emulsifiers preferably have a viscosity at 55 ° C of at least 500 centipoise. (The viscosity can be measured using a rotary disk viscometer of the Lab-Line Instruments Brookfield type). This application specifically describes the use of emulsifiers such as those designated by The Lubrizol Corporation (Wickliffe, OH) as OS-122102, OS-121863, PS-121864, 0S-80541J and OS-80691J, which are reaction products of (i) ) anhydride or hydrocarbyl substituted carboxylic acid (preferably an anhydride or substituted succinic acid of polyisobutylene); and (ii) an amine or alcohol, to form an ester or an amide product. The materials and methods for their manufacture are described in U.S. Patent No. 4,708,753, issued on November 24, 1987 to Fosberg [refer especially to Column 3, lines 32-38 and Column 8, line 10 to Column 26, line 68] and in U.S. Patent No. 4,844,756 issued July 4, 1989 to Forsberg, both incorporated herein by reference.

P10S3 It is believed that other materials that are useful in the present invention include substituted hydrocarbon succinic anhydrides such as those described in U.S. Patent 3,215,707 issued November 2, 1965 to Rense; U.S. Patent 3,231,587 issued January 25, 1996 to Rense; U.S. Patent No. 5,047,175 issued to Forsberg on September 10, 1991; and World Patent Publication No. WO 87/03613, published by Forsberg on June 18, 1987. All of these publications are incorporated herein by reference. Still other useful materials such as the emulsifier, in particular as a coemulsifier with a high viscosity primary emulsifier, are the ABA block copolymers of 12-hydroxystearic acid and polyethylene oxide. Other materials are described in U.S. Patent 4,875,927, issued to T. Tadros on October 24, 1989, which is incorporated herein by reference. A representative material of this kind useful as an emulsifier herein, is available from Imperial Chemical Industries PLC as Arlacel P135. While all of the materials described above can be used as a single emulsifier, it may be desirable to employ more than one emulsifier when the emulsion 12 is formed. In particular, when used P1063 a high viscosity emulsifier, a "sticky" feel may result when the treated article is subjected to shear stresses when in use to break up the emulsion 12. In this case, it may be desirable to use a coemulsifier of relatively low viscosity with the primary emulsifier, to allow the use of a minor amount of the main emulsifier, thereby decreasing stickiness. In a preferred embodiment of the present invention, a primary emulsifier available from Lubrizol (ie, reaction product of substituted succinic acid of polyisobutylene and an amine) and a secondary emulsifier is an ABA block copolymer of poly-12-hydroxystearic acid and Polyethylene oxide (e.g. Arlacel P135 from ICI) are used to provide an emulsion 12 with improved water retention time levels, as well as reduced beneficial tack (by reducing the level of the primary emulsifier). The skilled artisan will recognize that the various desired end uses will dictate whether multiple emulsifiers are appropriate, and the appropriate relative amounts of each if appropriate. A determination such as this will require only routine experimentation by the skilled artisan in view of the present exposition.

PÍO53 4. Optional Emulsion Components The internal phase high content inverse emulsions 12 of the present invention may also comprise other optional components typically present in solutions of this type containing moisture. These optional components may be present in either the continuous lipid phase or the internal polar phase and may include perfumes, antimicrobial (e.g., antibacterial) active pharmaceutical actives, deodorants, opacifiers, astringents, skin moisturizers and the like, as well as as mixtures of these components. All of these materials are well known in the art as additives to these formulations and can be employed in effective and appropriate amounts in the emulsions 12 of the present invention. A particularly preferred optional component that is included in the emulsions 12 of wet wiping cleansers according to the present invention is glycerin as a skin conditioning agent. The component of the emulsion 12 of the articles of the present invention is described and claimed here in terms of the components, and the corresponding amounts of the components, which are present after the formation of the emulsion 12. That is, PÍO53 when the stable emulsion 12 is formed and applied to the carrier. It is understood that the description (components and amounts) of the emulsion 12 also encompasses the emulsions 12 formed by combining the components and the levels described, regardless of the chemical identity of the components after emulsification and application to the carrier.

C. Other Components of Optional Items In addition to the reverse emulsion 12 of high internal phase content, there are other optional components that may be included in the articles of the present invention, typically for the purpose of improving the cleaning performance of the article when the phase internal polar of emulsion 12 is released. Certain of these optional components can not be present in the emulsion 12 at significant levels (eg, greater than 2% of the internal phase) because they can cause premature breakdown of the emulsion 12. These include various anionic detergent surfactants having relatively high HLB values high (eg, HLB from about 10 to about 25), such as sodium linear alkylbenzene sulfonates (LAS) or ethoxy alkyl sulfates (AES), as well as nonionic detergent surfactants such as alkyl ethoxylates, alkyl amine oxides, P1063 alkyl polyglucosides, switterionic detergent surfactants, ampholytic detergent surfactants and cationic detergent surfactants such as cetyl trimethyl ammonium salts and lauryl trimethyl ammonium salts. See U.S. Patent 4,597,898 (Vander Meer), issued July 1, 1986 (incorporated herein by reference), especially columns 12 through 16 for representative anionic, nonionic, switterionic, ampholytic and cationic detergent surfactants. Instead, these high HLB detergent surfactants can be applied or included in the article separately from the emulsion 12. For example, an aqueous solution of these high HLB detergent surfactants can be applied to the carrier either before or after the application from emulsion 12 to the carrier. During cleaning, the emulsion 12 is broken, releasing the components of the polar phase so that they can then be combined with the high HLB detergent surfactant to provide improved cleaning to the hard surface. Although the description of the invention relates, in general, to the application of a single emulsion 12 to the carrier, it is recognized that two or more different emulsions 12 can be used in the preparation of a single article. In these modalities, emulsions 12 P1063 may differ in a variety of ways, including unrestrictedly, the ratio of the internal polar phase and the external lipid phase, the emulsifiers used, the components used either for the internal phase, for the lipid phase or for both, and the similar. The use of multiple emulsions 12 in an article may be particularly desirable when two or more components are incompatible with each other, but may each be included in a separate emulsion 12. Alternatively, if a particular reaction is desired at the time of use, the reagents can be provided in separate emulsions. During the breaking of the emulsions 12 by shear stress during use, the desired reaction will occur. For example, when foaming is desired during the cleaning process, a moderate acid may be incorporated into the internal polar phase of an emulsion 12, while bicarbonate is incorporated into the internal polar phase of a second emulsion 12. During the breakdown , of the emulsions 12 by shear stress during use, the reactants interact to provide the desired foam. Descriptions of the suitable emulsion 12 are also found in commonly assigned World Patent Application WO 96/14835, published May 23, 1996 in the name of Mackey et al., And incorporated herein by reference.

P1063 A Preferred Pattern As noted in the above, the emulsion 12 can be applied to the substrate 10 in a discontinuous pattern. As noted above, a discontinuous coating is a coating wherein the regions of the substrate are free of the intermediate regions of coating the substrate on which the coating is placed. Suitable discontinuous patterns comprise regions of discrete islands of emulsion 12, essentially continuous networks of emulsion 12 and discrete micropatterns of emulsion 12. In a preferred embodiment, emulsion 12 is applied in discrete strips of emulsion 12, as shown in Figure 12. The strips are preferably continuous, as illustrated, but may alternatively comprise a pattern of discrete, discontinuous segments that collectively comprise a strip. If the strips are selected, the strips are oriented, preferably, in the direction of the machine, to facilitate their manufacture. The emulsion 12 can be applied to the substrate 10 and placed thereon by any suitable means well known in the art, such as for example gravure printing, flexographic printing, spraying and, preferably, extrusion. More preferably, the emulsion 12 is extruded as a series of shaped beads Continuous cylindrical P1063. A continuous cylindrical shape is preferred by the emulsion 12 because this shape reduces the ratio of surface area to volume, of the emulsion 12. The straps can be straight, as shown, can be sinusoidal in configuration, etc. If the strips are selected in sinusoidal form, preferably the strips are in phase, so that the parallelism is maintained and that each strip remains equally separated from the adjacent strips. It is desired that the emulsion 12 have the minimum possible ratio of surface area to volume. Minimizing the ratio of surface area to volume reduces the water loss of emulsion 12 due to evaporation. Preferably, the emulsion 12 has a surface area to volume ratio of less than or equal to about 4 / unit length, more preferably less than or equal to about 3 / unit length and most preferably, less than or equal to about 2 / unit length, wherein the unit length is measured in the cross section of the emulsion 12. Suitable proportions of surface area to volume for the cylindrical emulsion beads 12 vary from about 400 to 200 inches "1 and preferably approximately 75 to 125 inches" 1.

However, optimal results are not achieved by presenting a single unit emulsion sphere 12 for the user with the wipe 30. While such an arrangement would likely provide adequate water, the water distribution would be highly localized and could not be dispersed properly. in the entire surface area of the wipe 30. Preferably, the distribution of the emulsion 12, or more particularly, the release of water therefrom, approximates the perception of a spray of water on the skin. It will be apparent to a person skilled in the art that as the basis weight and absorbency of the substrate 10 increases, the amount of water needed to locally saturate the substrate 10 would increase in the same way. Therefore, to the extent that the basis weight and / or the absorbency of the substrate 10 increases, the amount of emulsion 12 applied to the substrate 10 must increase proportionally. Preferably, about 5 to 35 percent and more preferably about 10 to 25 percent of the surface area of the wipe 30 has emulsion 12 disposed thereon. During the break, the emulsion 12 locally moistens the corresponding regions of the substrate 10. The moistened portion of the substrate 10 can vary from about 10 to 90 P1063 percent of the surface area of the substrate 10, with, of course, the remainder of the surface area of the substrate 10 remaining dry due to the discontinuous pattern. It will be apparent that when in use, the percentage of moistened surface area will be greater than the percentage of the surface area initially coated by the emulsion 12. It will be further understood that, of course, the entire towel 30 can be moistened according to a function of time and / or use of the wipe 30. In this way, the beads of the emulsion 12 are applied, preferably to the substrate 10 in an arrangement that adjusts both the diameter and the spacing of the beads in a preferred geometry. The amount of water carried by the emulsion 12 increases according to the square of the diameter of the beads. Therefore, while the diameter of the beads increases, the spacing between the adjacent strips of the emulsion 12 must be increased in the same way. Suitable spacings between adjacent emulsion beads vary from about 0.030 to 1,500 inches and, preferably, from about 0.175 to 0.375 inches. If the emulsion 12 is to be exposed directly to the surface, that is to say, arranged on the outside of the substrate 10 as the towel 30 is presented to the user, the emulsion 12 preferably comprises a P10S3 level of at least approximately 25 percent, more preferably of at least about 50 percent and more preferably, at least about 75 percent of the level of the basis weight of the substrate 10. Alternatively, if the emulsion 12 is placed between two sheets of substrate 10 in a laminated construction, for tissue applications, preferably the emulsion 12 comprises at least about 150 percent, more preferably at least about 200 percent and most preferably at least about 250 percent of the combined basis weight of the two leaves. In a laminated construction of this type for hard surface cleaning applications, preferably, the emulsion 12 comprises at least about 500 percent, more preferably at least about 650 percent and more preferably, at least about 800 percent of the combined basis weight of the two leaves. It should be noted that the basis weights described herein refer to the total base weights of the substrate 10, as an average of the various regions of different basis weight contained within the substrate 10. The basis weight of the substrate 10 can be measured in accordance with the Method of Test ASTM D3776-9, whose test method is incorporated here as a reference, with results reported in pounds P1053 for 3,000 square feet. The weight of the emulsion 12 is measured gravimetrically once the base weight of the substrate 10 is known, such as tare. If desired, the uncoated regions 34 of the substrate 10 free of the emulsion 12 may be slightly wider in the transverse direction (transverse to the machine) at the edges of the wipe 30 than the corresponding uncoated regions 34 disposed therein of the wipe 30. This arrangement adjusts the processing and cutting into strips of a wide, multi-roll paper web of the wipe 30 into narrower discrete units to transport and sell to consumers. It will be apparent to a person skilled in the art that the uncoated regions 34 free of the substrate can form an edge at the ends of the wipe 30 as well. This geometry can be easily achieved by applying the emulsion 12 in discontinuous form. Instead, the emulsion 12 can be applied intermittently in the machine direction. The substrate 10 is then cut or perforated in the transverse direction to the machine coinciding with the free regions 34 of the emulsion 12 in order to provide discrete or separable wipes 30. Referring again to Figure 10, the emulsion 12 can define decorative figures such as P1063 macropatterns. The macro patterns can be used as shown, or they can be superimposed on the strip pattern of the emulsion 12 described with reference to Figure 12. The emulsion macropatterns 12 provide the advantage that stronger water loads can be applied locally from a pattern that provides an aesthetically pleasing visual guide for the user from where the emulsion 12 is present. The macropatterns of the emulsion 12 can form decorative figures. The decorative figures can be provided in the form of flowers, butterflies, clouds, markings, advertising, or any other flat pattern devised by the user. In a preferred embodiment, the substrate 10 comprises a tissue of multiple basis weights. A substrate 10 of multiple basis weights can be made in accordance with the aforementioned patents which describe it and which were incorporated herein by reference. A substrate 10 of multiple basis weights provides the advantage that the excess water will more easily saturate the low basis weight regions and, therefore, will apply more quickly to the surface. Preferably, the substrate 10 of multiple base weights comprises a network region of substantially continuous high basis weight with discrete regions of low basis weight distributed throughout the essentially continuous network.

P1063 Alternatively, a substrate 10 having a semi-continuous pattern of high and low basis weight regions can be selected. Still in a less preferred embodiment, a substrate 10 having an essentially continuous network of low basis weight regions with discrete regions of high basis weight distributed therein may be used, provided, however, that one is willing to accept the inherent resistance transaction in a substrate 10 such as this one. Such a substrate 10, prophetically, provides the benefit that the essentially continuous pattern of low basis weight regions will allow more quickly that the water squeezed out of the emulsion 12 to penetrate the substrate 10 and be transferred to the surface. If the substrate 10 having a region of essentially continuous high basis weight is selected, preferably the separation of the discrete regions of low basis weight is less than the separation between the adjacent strips of the emulsion 12. This relative difference in the separations ensures that the emulsion 12 will intercept the low basis weight regions and will be more easily transmitted through it, as described above. For the embodiments described herein for tissue applications, a substrate 10 having a basis weight of approximately 7 to 10 pounds per 3,000 feet P1063 squares per sheet and from about 50 to 300, and more preferably from about 100 to 200 discrete regions of low basis weight per square inch, is adequate. For hard surface cleaning applications, a substrate 10 having a basis weight of about 20 pounds per 3,000 square feet and about 100 to 200 discrete regions of low basis weight per square inch is suitable. In a preferred embodiment, the wipe 30 can be made in accordance with commonly assigned U.S. Application No. 08 / 886,764 entitled "Cleaning Articles Comprising a Cellular Fibrous Structure Having Discrete Basis Weight Regions Treated with A High Internal Phase Inverse Emulsion ", presented on July 1, 1997, in the name of Nicholas J. Nissing et al., the exhibition of which is incorporated herein by reference. If the substrate 10 having a semi-continuous basis weight pattern is selected, the substrate 10 can be made in accordance with commonly assigned United States Patent No. 5,628,876, issued May 13, 1997 to Ayers et al. , and incorporated here as a reference. Preferably, the semi-continuous pattern is oriented in the machine direction. If this geometry is selected, prophetically, the emulsion beads 12 can be applied to the substrate 10 of semicontinuous pattern of P1063 so that the emulsion 12 is juxtaposed with, and preferably coincident with, the low basis weight regions of the substrate 10. This arrangement provides the advantage, set forth in the foregoing, that the water squeezed out of the emulsion 12 is more easily transmitted through of the low basis weight regions of the substrate 10 of semicontinuous pattern. The low basis weight regions of the semi-continuous pattern, if parallel to the machine direction, can be arranged in a gap less than or equal to the strips of the emulsion 12. It will be apparent to a person skilled in the art that they are possible. many variations and which are within the scope of the claimed invention. For example, a laminated construction comprising the emulsion 12 disposed between two sheets of substrate 10 can be processed as described above. It is not necessary, however, that the sheets are identical. A sheet can be non-woven for strength. The other sheet may be a tissue to provide water transmission to the surface. If desired, the non-woven sheet can be treated to make it hydrophobic and thereby ensure that the water released from the emulsion 12 is transferred to the surface by means of the tissue sheet. Alternatively, a laminate comprising two sheets of tissue may be selected. One of the leaves P1063 may have a region pattern of multiple basis weights described in the foregoing. The region of multiple base weights may comprise a semi-continuous pattern described in the foregoing. The other sheet may comprise a single region of basis weight, by resistance. This modality provides greater water transmission through one of the leaves than through the other leaf. Alternatively, the sheet of the multiple base weight region may comprise an essentially continuous network of high basis weight regions with discrete low basis weight regions distributed therein. In yet another embodiment, a laminate having a plurality of various sheets can be provided. The sheets may comprise alternate sheets of substrate 10 and emulsion 12. A laminate such as this may have two sheets of substrate 10 facing outwards, as described above. The emulsion 12 can be completely contained within the laminate. Alternatively, the emulsion 12 may be disposed on an exposed surface of one of these laminates. Still in another modality, the emulsion strips 12 may be comprised of discrete emulsion spheres 12. discrete spheres of emulsion 12 are preferably juxtaposed to collectively form the discontinuous pattern. This arrangement provides the advantage of P1063 a suitable ratio of surface area to volume, similar to the beads generally formed in cylinders described above. Although the strips of discrete spheres are preferred, a person with ordinary skill will understand that the discrete spheres of the emulsion 12 can be juxtaposed to form any desired discontinuous pattern. Yet another variation is to vary the amount of emulsion 12 within the discontinuous pattern. For example, certain emulsion strips 12 may have relatively more emulsion 12 than other strips. This arrangement allows locally heavier loading of the water on the surface to be cleaned, but still provides relatively drier edges to minimize the amount of residual water remaining on the surface. It will be evident that, depending on the desired application, the wipes 30 can be provided as discrete units, they can be joined successively by means of perforations, etc. The wipes 30 can be dispensed individually, as is normally done for facial tissues. If individual dispatch is desired, wipes can be provided in dispatcher "jumping" or to be taken from the dispatcher, as set forth in commonly assigned United States Patents, No. 4,623,074 granted on November 8, 1986 to P1063 Dearwester; 5,520,308 issued on May 28, 1996 to Berg. Jr. et al. and 5,516,001 granted on May 14, 1996 to Muckenfuhs et al., whose expositions are incorporated herein by reference. Alternatively, the wipes 30 can be center coiled, as set forth in commonly assigned U.S. Patent No. 5,318,235 issued June 7, 1994 to Sato, the disclosure of which is incorporated herein by reference. as reference. If desired, the wipes 30 can be lightly compressed for packing, provided care is taken not to break the emulsion 12. This packing can be accomplished as disclosed in commonly assigned U.S. Patent No. 5,664,897, issued on July 8, 1997 to Young et al., The exhibition of which is incorporated herein by reference. Accordingly, while the particular embodiments of the present invention have been illustrated and described, it will be obvious to those skilled in the art, that various other changes and modifications may be made without departing from the spirit and scope of the invention. It is therefore intended to cover all the changes and modifications within the scope of this invention in the appended claims.
