Abstract

Disclosed are disposable cleansing articles (1) which comprise a multi-phase, multi-component emulsion (5) and an activation web (2) that facilitates activation of the emulsion during use. In a preferred embodiment, the multi-phase emulsion is a high internal phase inverse emulsion having a continuous external lipid phase and a discontinuous internal polar phase. During use, the activation web facilitates breakage of the emulsion's external phase, thereby releasing the internal phase for its desired use. Because the internal liquid phase may account for up to about 97 % of the emulsion, significant levels of fluid (e.g., water or a polar liquid) may be delivered from a "dry" wipe.

Description

AREA OF INVENTION

The The present invention relates to articles that are in a broad sense Variety of cleaning applications are useful. The invention refers in particular to wet cleaning wipes, the from a textured carrier substrate made with a multi-phase, multi-component emulsion which can be activated to have a liquid Phase free.

BACKGROUND THE INVENTION

On the field of personal Cleaning and household cleaning a number of approaches have been developed the cleaning needs to fulfill. These approaches can largely into two main categories: those which is a substantially dry substrate and a separate detergent use, and those that have an integrated combination of substrate / detergent use.

Of the The first approach is typically one in which the user a dry substrate of its choice with the desired absorption and texture properties used. Usually used substrates include disposable and reusable Paper towels, Textile fabrics of natural and / or synthetic origin and the like. The user brings then an emulsion of the desired Composition on the target surface and / or on the dry Substrate and then brings the substrate to the target surface for the desired wiping or cleaning activity on. Although this approach over has been used for many years, it forces the user to separate To maintain supplies with substrates and emulsions. Furthermore it is common uncomfortable, the emulsion at remote locations in the container types, which are typically used to transport. Also subject it tries and mistakes that to determine the appropriate effective amount of an emulsion to be applied.

In an effort to meet these consumer needs in the most recent Time integrated products developed from substrate / cleaning agents, in which the substrate for packed the use with the already applied desired amount of emulsion is. One such example of a product of this type is the Pre-packed, pre-moistened Tuchlette, commonly found in convenience stores available for cleaning before and after meals. Another example are the pre-moistened "baby wipes" that are often used for activities used for child care. Although such products one they have to enjoy a fair degree of economic success a certain degree of packaging, to prevent evaporation, pollution or to prevent decomposition of the emulsion before use. About that It is also dependent from the desired Context inconvenient to dispose of the packaging, and, in the case of Multi-product packaging to separate wet substrates for single use.

The US-A-3965519, Hermann I.F. describes a disposable floor polishing cloth with a bonding material that forms a three-dimensional pattern. WO-A-96/14835 by Mackley L.N. and WO-A-96/34035 by Mackley L.N. both wet wipes for the perianal use with an emulsion.

In recently, Time, integrated substrate / detergent products have been developed, which the needs in terms of preserving a "wet" or activated device in one usable condition. These articles use a textured carrier substrate that comes with a Multiphase emulsion was treated, which is a dispersed polar Has phase and a continuous lipid phase. Have these items a number of significant advantages over previous cleaning products, especially if they are in the form of wet cleaning wipes. These articles set significant amounts of the inner polar phase (e.g., water) during Use free to effectively perform a cleaning. The continuous lipid phase of the emulsion is sufficiently brittle, so that they through a Very little shearing contact can be easily destroyed (for example, during the Wiping on the skin) to release this inner phase easily, but is sufficiently firm to allow early release of the internal Phase during to avoid the rigors of the treatment. The continuous lipids Phase of this article is also sufficiently stable during the Storage, allowing a significant evaporation of the inner polar Phase is prevented.

These articles can be used in many applications requiring the delivery of a polar or liquid inner phase, such as water, as well as active ingredients that are dispersible in such polar materials. These applications include cleaning hard surfaces of floors, counters, Ba taverns, toilets and the like, as well as the delivery of antimicrobial or pharmaceutical active substances which are soluble or dispersible in polar liquids. These articles can also perform several functions. For example, the emulsion applied to these articles may be formulated to have advantages at the same time of cleansing and waxing when used on articles such as furniture, shoes, automobiles, and the like.

Even though Articles of this variety have proven successful in use, it is often difficult either to activate a sufficient amount of the emulsion the need to meet the end user, or efficiently, the whole capacity of the emulsion loaded in the article leave. Therefore, it is common necessary, overcompensation to bring about by satisfying the emulsion charge on the carrier material, to make sure that an adequate amount of the inner polar Phase for the use available is done.

Accordingly, it would be desirable a cleaning article with an integrated substrate / activating agent to create which one for efficient use of the active agent.

It would be further desirable, to provide such a cleaning article, which for easy activation ensures the release and release of the active substance.

In some cases can be firm Polyol polyester also provide some emolliency functionality.

typically, is the main component of inverse high internal emulsions Phase of the present invention, the dispersed inner polar Phase. This inner phase can have a number of different advantages deliver when they are set free. In preferred embodiments The polar phase becomes a significant percentage of water contain. For example, in preferred moist cleaning wipes for the perianal Purify the inner polar phase a significant proportion of Contain water; provides this released inner water phase the primary Cleaning effect for these wipes. In these preferred embodiments The polar phase becomes a significant percentage of water contain, preferably at least 60 wt.% Of the inner polar Phase, more preferably at least 75% by weight, more preferably at least 85% by weight.

In preferred embodiments, in which the inner phase contains significant amounts of water, the inner polar phase may comprise other water-soluble or dispersible materials that enhance stability not adversely affect the inverse high internal phase emulsion. One such material, typically contained in the inner water phase, is a water-soluble electrolyte. The dissolved electrolyte minimizes the tendency of the materials present in the lipid phases to dissolve also in the water phase. An electrolyte which can impart ionic strength to the water phase can be used. Suitable electrolytes include the water-soluble mono-, di- or trivalent inorganic salts, such as the water-soluble halides, for example chlorides, nitrates and sulfates of alkali metals and alkaline earth metals.

Other water-soluble or dispersible materials that may be present in the internal water phase include poly-catianic polymers to provide sterol stabilization at the water / lipid interface and nonionic polymers that also stabilize the water-in-lipid emulsion. Suitable polycationic polymers include Reten 201, Kymene ^® 557H and Acco 711. Suitable nonionic polymers include polyethylene glycols (PEG) such as Carbowax. These polycationic and nonionic polymers are typically contained in a concentration ranging from 0.1 to 1.0% of the water phase.

In addition to or as an alternative to the content of water, the internal polar phase may include polar materials including solvents such as ethanol, isopropanol, butanol, and hexanol; Glycols or substituted glycols such as propylene glycol, butylene glycol, 2,2,4-trimethylpentane-1,3-diol or hexylene glycol; Polyglycols such as diethylene glycol or triethylene glycol; Glycol ethers, such as short chain (eg, C ₁ -C ₆ ) derivatives of oxyethylene glycol and oxypropylene glycol, such as mono- and diethylene glycol, N-hexyl ether, mono-, di-, and tri-propylene glycol, N-butyl ether, and the like. Also, solvents such as tetrahydrofuran, dimethyl sulfoxide, acetone and the like may be contained in the inner polar phase.

A another key component the inverse high internal phase emulsion of the present invention is an emulsifier. In the emulsions of the present invention the emulsifier is contained in an effective amount. What constitutes an "effective amount" depends on a number of factors, including their respective quantities lipid components and components of internal polar Phase, the type of emulator used, the proportion in the emulsifier existing impurities and similar factors. typically, The emulsifier comprises from 1 to 10% of the emulsion. Preferably comprises the emulsifier from 3 to 6% of the emulsion. Most preferably, the Emulsifier from 4 to 5% of the emulsion. Although the singular "emulsifier" is used, To describe this component can be more than one emulsifier used when the emulsion is formed. In fact, can it desirable be, as discussed below, both a primary also a secondary one Emulsifier to use when certain materials are used. Although not limiting the scope of the invention should, where two emulsifiers are used is preferred, that the primary Emulsifier from 1 to 7% by weight, more preferably from 2 to 5% by weight, most preferably from 2 to 4% by weight of the emulsion; and the secondary emulsifier from 0.5 to 3% by weight, more preferably from 0.75 to 2% by weight, most preferably from 0.75 to 1.5% by weight of the emulsion.

Such emulsifiers are described in detail in US Patent US-A-5,756,112, filed on April 27, 1995 by L. Mackey (Case 5653).

Other suitable emulsifiers are described in US Pat. No. 5,952,043, filed November 9, 1994 by L. Mackey et al. (Case 5478). The emulsifiers described herein include certain sorbitan esters, preferably the sorbitan esters of C ₁₆ -C ₂₂ saturated, unsaturated or branched fatty acids. Because of the manner in which they are typically made, these sorbitan esters usually comprise mixtures of mono, di, tri, etc. esters. Representative examples of suitable sorbitan esters include sorbitan monooleate (eg, SPAN ^® 80), sorbitan sesquioleate (eg, Arlacel ^® 83), Sorbitanmoniisostearat (eg CRILL ^® 6 made by Croda), sorbitan stearates (eg, SPAN ^® 60), Sorbitantriooleat (eg, SPAN ^® 85), sorbitan tristearate ( for example, SPAN ^® 65) and sorbitan dipalmitates (eg, SPAN ^® 40).

In addition to these primary emulsifiers, co-emulsifiers can be used to provide additional stability of the water-in-lipid emulsion. Suitable co-emulsifiers include phosphatidylcholines and phosphatidylcholine-containing compositions, such as the lecithins; long chain C ₁₆ -C ₂₂ fatty acid salts such as sodium stearate, long chain C ₁₆ -C ₂₂ dialiphates, short chain C ₁ -C ₄ dialiphate quaternary ammonium salts such as ditallowdimethylammonium chloride and ditallowdimethylammonium methylsulfate; long chain C ₁₆ -C ₂₂ dialkoyl (alkenoyl) -2-hydroxyethyl, short chain C ₁ -C ₄ dialiphatic quaternary ammonium salts such as ditallowoyl-2-hydroxyethyldimethylammonium chloride, the long chain C ₁₆ -C ₂₂ dialiphatic imidazolinium quaternary ammonium salts such as methyl-1-tallowamidoethyl 2-oleylimidazolinium methylsulfate and methyl 1-oleylamido-2-ethylimidazolinium methylsulfate; short chain C ₁ -C ₄ dialiphates, long chain C ₁₆ -C ₂₂ monoaliphatic benzyl quaternary ammonium salts such as dimethylstearylbenzylammonium chloride and synthetic phospholipids such as stearamidopropyl PG-dimonium chloride (Phospolipid PTS from Mona Industries). Interfacial tension modifiers such as cetyl and stearyl alcohol for closer packing at the water-lipid interface may also be included.

Further Emulsifiers used in the manufacture of the articles of the present Invention useful include, the high viscosity emulsifiers disclosed in US Pat. No. 5,980,922 on April 30, 1996 by L. Mackey and B. Hird. These emulsifiers preferably have a viscosity at 55 ° C of at least 500 centipoise. (the viscosity can be measured using a laboratory grade instrument in the manner of a rotary disk viscometer from Brookfield.). The application specifically describes the use of emulsifiers, such as those designated by The Lubrizol Corporation (Wickliffe, OH), as OS-122102, OS-121863, OS-121864, OS-80541) and OS-80691J, which are reaction products are of (i) a hydrocarbyl-substituted carboxylic acid or Anhydride (preferably a polyisobutylene substituted succinic acid or anhydride); and (ii) an amine or alcohol to form an ester or to form amide product. The materials and the processes for their production are described in US Pat. No. 4,708,753 issued November 24 1987 for Forsberg [see in particular column 3, lines 32-38; and column 8, line 10 to column 26, line 68] and US Patent No. 4,844,756, released on 4 July 1989 for Forsberg.

Further Materials which may be useful in the present invention include hydrocarbon-substituted succinic anhydrides, such as which are described in US Patent 3,215,707, issued on 02nd November 1965 for Rense; U.S. Patent 3,231,587 on January 25, 1996 for Rense; U.S. Patent No. 5,047,175 issued to Forsberg on September 10, 1991; and World Patent, Publication Number WO 87/03613, released by Forsberg on 18 June 1987.

Yet other materials that are useful as emulsifiers, especially as Coemulsifier with a highly viscous primary emulsifier, are ABA block copolymers of 12-hydroxystearic acid and Polyethylene oxide. Such materials are described in US Patent 4,875,927, published for T. Tadros on October 24, 1989. A representative material for this Class, useful here as an emulsifier is available from Imperial Chemical Industries PLC as Arlacel P135.

As indicated, although all materials described above may be used as a single emulsifier, it may be desirable to use more than one emulsifier when the emulsion is formed. In particular, when a high-viscosity emulsifier is used, a certain "sticky" feel may arise when the treated article is subjected to user-shear printing using the Break emulsion. In this case, it may be desirable to use a relatively low-viscosity co-emulsifier with the primary emulsifier to allow the use of a small amount of the main emulsifier, where the tackiness is avoided. In a preferred embodiment of the present invention, a primary emulsifier obtainable from Lubrizol (that is, reaction product of polyisobutylene-substituted succinic acid and an amine) and a secondary emulsifier which is an ABA block copolymer of poly-1,2-hydroxystearic acid and polyethylene oxide (eg, ICI's Arlacel P135) can be used to provide an emulsion with improved water retention levels over time as well as favorably reduced tackiness (above the point of reducing the proportion of the primary emulsifier). Those skilled in the art will recognize that different desired end uses will dictate whether multiple emulsifiers are suitable and the appropriate relative amounts of each, if appropriate. Such determination will only require routine testing by those skilled in the art in light of the present disclosure.

The high internal phase inverse emulsions of the present invention can Also include other optional components that typically in moisture-containing emulsions of this type are present. These optional components can either in the continuous lipid phase or in the inner polar phase and perfumes, antimicrobial (e.g., antibacterial) Active ingredients, active pharmaceutical ingredients, deodorants, opacifiers Astringents, skin conditioners, cosmetics, cleaners, surface conditioners, Insect repellent, PH buffer and the like, and mixtures of these components. All of these materials are in the art as additives for Such formulations are well known and can be used in effective, appropriate Quantities can be used in the emulsions of the present invention. A particularly preferred optional component used in the emulsions wet cleaning wipes according to the present Invention is glycerol as a skin conditioning agent.

The Emulsion component of the articles of the present invention described and claimed herein by components (ie, lipid phase components, internal polar phase components, emulsifier components) and corresponding amounts these components, which are present after the emulsion formation. This means, when the stable emulsion is formed and applied to the carrier becomes. It should be understood, however, that the description (components and amounts) of the emulsion also includes emulsions formed by combining formed of the components described in the proportions described irrespective of the chemical identity of the components after the Emulsification and application to the carrier.

D. Activation Lanes

In agreement With the present invention, the cleaning article also includes a sheet a material that forms an activation lane to release upon release a liquid to help out of the multiphase multi-component emulsion when used by one User "activated".

The Activation lane of the present invention is an activation lane from interconnected fibrous elements forming a pattern network from pentagonal form shaped capillaries.

Around "activate" the multiphase multi-component emulsion, have two physical properties in combination as improving the effectiveness of such cleaning articles out put by the degree of disruption of the continuous Phase of the emulsion is improved and the release of the active portion improves the emulsion from the interior of the article to the outer surface will, where to go for the intended function can be effectively used.

One feature that has been found to be important in activation webs of the present invention is a textured surface on the side or portion thereof, the activation web, which directly contacts the multiphase, multi-component emulsion during use. By "textured" is meant that the surface of the web has extensions beyond the two-dimensional plane bounded by the macroscopic trajectory. In other words, the activation path comprises a surface with a three-dimensionality. Without being bound by it, Applicants believe that such a surface imparts a degree of abrasiveness to the web surface, thereby helping to provide a friction activating property to break the continuous outer lipid phase and release the inner liquid phase from the emulsion put. Varying levels of abrasion can be selected by appropriately selecting the material of the activating sheet and the surface geometry. However, the activation lane should preferably provide sufficient relative lateral movement between the activation lane and the overlaying optional secondary lanes so as to provide shearing action on the multiphase emulsion thereby inhibiting release of the inner liquid phase terstützen.

A another property that is important in the activation pathways of the present invention, is the elasticity. activation pathways in accordance with the present invention should have an elastic property show, at least for a period of time that is typical for the article which enables the webs to be textured or three-dimensional character during activation of the emulsion to keep. For The purpose of the present invention is the elasticity of the activation web through their relationship from wet thickness to dry thickness (hereinafter referred to as "elasticity ratio"). Wet elasticity is measured in accordance with the procedure described below in the Test Procedure section becomes. The activating sheets of the present invention will have elasticity ratio of at least 0.9. Preferably, the activation lanes become a elasticity ratio of at least 0.95, more preferably at least 0.98. As stated, the activation lane should have the required elasticity ratio for a period of time which corresponds to the typical period of use of the article. So the activation path does not have the required limitless Show elasticity ratio. As will be discussed below, in certain embodiments the activation lane is a synthetic material (e.g., a polymeric material) Network) printed on a cellulosic material is. It is obvious that, although the cellulosic component of the activation element in the wet state to some extent coincide can (that is, will not be "elastic") polymeric network has its three-dimensional, textured character will keep and the desired Activation of the emulsion will create. In such embodiments the elasticity ratio is so adjusted that alone by the cellulosic component caused elasticity reduction is compensated.

Additionally, that an abrasive character with the help of a textured surface ready is made and the required elasticity ratio is created is the textured surface the activation lane in direct contact with the multiphase multicomponent emulsion while preferably a significant amount of a built-in void volume to provide which one for the emulsion accessible is. This gap volume provides a receiving space to receive the solid phase of the emulsion and withhold, if they are from the active liquid Phase during the activation process is separated, such that this part the emulsion does not affect the release or functioning of the liquid phase disturbs and / or leaves the cleaning article, when he is during use contaminate external surfaces could.

A another property that has arisen to optionally desired attributes in cleaning articles in accordance to provide with the present invention is a permeability. In accordance with the present invention, the activation web need not be permeable and can actually be liquid impermeable, at least for the liquid, which forms the multiphase multicomponent emulsion. In a such embodiment would the Activation path form a barrier and make sure that the released liquid remains on one side of the activation path. A liquid-permeable activation web however allows the liquid enter into the activation path, and, depending on from the design of the entire cleaning article, the one or several outer layers of the article on both opposite sides of the activation lane for the desired Use to wet.

For activation tracks, which permeable are, is an extra Property which for certain applications should be beneficial, the capillarity. If the fluid properties the special liquid Component of the relevant multiphase multicomponent emulsion the activation lane can be provided with passageways for the liquid which from a surface to the other surface extend and act as capillary structures for the particular fluid used impact. Accordingly, the Activating path a preferred liquid flow direction ready to make a liquid from one side of the activation lane to the other side of the activation lane to steer. Such a fluid motive power Also tends to be the fluid flow in the opposite direction. Such capillaries Properties can for many Functions are used, such as for providing a one-sided cleaning article, in which a page through the liquid is wetted to create an active cleaning surface, while the other side essentially unwetted by the therein liquid remains.

In addition, it has proven advantageous to use an activation web with a thermoplastic material. Such materials, while not essential to the present invention, provide an additional advantage over those provided by non-thermoplastic materials. Namely, such a web provides a material which can readily be thermally bonded to another component of a cleaning article, such as non-thermoplastic secondary webs, in the absence of adhesives and other binding agents.

One Material that for the use in accordance with the present invention comprises a three-dimensional, macroscopically expanded, formed film web of a polymeric Material, such as a polyethylene, polypropylene or another suitable material as a carrier for the emulsion. With openings provided shaped films are preferred because they are permeable for liquids and are not yet absorbent and also have a tendency to a preferred liquid flow to show in one direction. Suitable shaped films are described in US Pat. No. 3,929,135 for Thompson on December 30, 1975; U.S. Patent No. 4,324,246 for Mullane et al. on April 13, 1982; U.S. Patent No. 4,342,314 for Radel et al. on the 3rd of August, 1982; U.S. Patent No. 4,463,045 for Ahr et al. on July 31, 1984; 4,637,819, published for Ouellette et al. on January 20, 1987 and US Patent No. 5,006,394 for Baird on April 9, 1991. Other suitable shaped films include hydroformed Films such as those disclosed in US Patent No. 4,629,643, published on December 16, 1986 for Curro et al. and U.S. Patent No. 4,609,518, issued September 2, 1986 for Curro. The shaped films would preferably have micro-openings formed therein.

2 Figure 3 is an enlarged, partially segmented, perspective view of a particularly preferred embodiment of an apertured, macroscopically expanded, three-dimensional, fibrous, liquid pervious, polymeric web 40 generally in accordance with the teachings of commonly assigned U.S. Patent No. 4,342,314 issued to Radel et al. on August 3, 1982, which has been found suitable for use as a topsheet of absorbent articles. The term "macroscopically expanded," when used to describe three-dimensional plastic sheets of the present invention, refers to sheets, tapes, and sheets which have been made to conform to the surface of a three-dimensional forming structure so that both surfaces thereof show a three-dimensional pattern of surface asperities corresponding to the macroscopic cross section of the forming structure, the surface irregularities having the pattern being individually perceptible to the normal naked eye, that is, a normal naked eye with 20/20 sight, not assisted by an instrument that changes the visual size or distance of an object or otherwise changes the visual power of the eye when the vertical distance between the observer's eye and the plane of the trajectory is about 12 inches (30.5 cm). The term "fibrous" as used herein to describe the appearance of plastic webs of the present invention generally refers to a fine pattern of apertures of random or nonrandom type, reticulated or non-reticulated resulting in an overall appearance and appearance a woven or nonwoven fibrous web when viewed by the naked human eye.

As in 2 As can be seen, the fibrous appearance of the web comprises a continuum of fibrous elements, with the opposite ends of each fibrous element joined to at least one other of the fibrous elements. In the in 2 In the disclosed embodiment, the interconnected fibrous elements form a pattern network of pentagonal shaped capillaries 41 , The train 40 , which shows a fibrous appearance, embodies a three-dimensional microstructure extending from the first surface 42 the train in the plane 43 to their second surface 44 in the plane 45 which is used in absorbent articles for rapid liquid transport from the first surface 42 to the second surface 44 to support the web without transversely transferring liquid between adjacent capillaries 41 , As used herein, the term "microstructure" refers to a structure of such a fine degree that its minute detail is readily apparent to the human eye only by magnification through a microscope or other means well known in the art can be taken true.

openings 47 in the first surface 42 are formed by a plurality of intersecting fiber-like elements, for example elements 48 . 49 . 50 . 51 and 52 that are verbun to each other on the bodyside surface of the web. Each fibrous element comprises a base region, for example the base region 54 who is in the plane 43 lies. Each base region has a sidewall region, for example the sidewall regions 56 which are attached to each edge of the same. The sidewall areas 56 generally extend in the direction of the second surface 44 the train. The intersecting sidewall portions of the fibrous elements are joined together between the first and second surfaces of the web and terminate substantially in-plane with each other 45 the second surface.

In the in 2 shown specifically preferred embodiment terminate the interconnected side wall portions 56 essentially together in the plane 45 the second surface 44 to openings 58 in the second surface 44 to form the track. The network of capillaries 41 passing through the interconnected sidewall areas 56 between the openings 47 and 48 allows free transfer of liquids from the uppermost surface of the web directly to the lowermost surface of the web without cross-transfer of liquid between adjacent capillaries.

The base area 54 can be a microscopic pattern of surface irregularities 60 Generally, in accordance with the teachings of commonly assigned U.S. Patent No. 4,463,045 issued to Ahr et al. on July 31, 1984. When used in a visible configuration, the microscopic pattern provides surface asperities 60 a substantially non-shiny visible surface when the web 40 is hit by incident light rays.

When used as an activation lane, as in the embodiment of FIG 1 can be shown, the shaped film web 2 be used so that the first surface 42 the multiphase multi-component emulsion 5 is facing and touched directly. However, it is presently preferred to have the second surface 44 to use as the surface which directly contacts the emulsion during use. In such a configuration, the three-dimensional nature of the formed film provides its unevenly broken openings 58 in the second surface, an increased abrasive property compared to the first surface so as to provide an improved activation property in accordance with the present invention.

Accordingly provides such a material, if it acts as an activation path in accordance is used with the present invention (i) for a three-dimensional surface topography on the side of the material, which initially directly the multiphase Multi-component emulsion during touched, (ii) for a three-dimensional void volume, (iii) for wet elasticity, (iv) comprises a capillary structure; and (v) provides heat sealable material useful is when assembling the cleaning article.

Additionally, that thermoplastic films are used as activation webs, can relatively untextured orbits are modified in such a way that the texture amount increased significantly will be, with which the emulsion is touched, and thereby the fluid delivery of the article is improved. A special method for modifying such an untextured web is one or more Textured elements to print on a relatively untextured web. The printed component can cover the entire surface or just one Part of the surface, which is in contact with the emulsion. Potential embodiments include, for example, printed polymeric networks, unbound Particles or particles adhered to the substrate are printed Polymers "hooks", which in detail are described in US Patent Nos. 5,230,851, 5,318,741, 5,058,247, 5,116,563, 5,180,534, 5,540,673, 5,326,415, 5,325,569, 5,392,498, 5,300,058, 5,385,706, 5,397,317 and 5,586,979. It is for the expert It is clear from the prior art that this technique applies to each of its wide variety of substrates can be applied such that the total elasticity ratio of Materials increased and the entire texture that is in contact with the emulsion, is increased. For The purpose of this invention is a modified web such as described here, require that the calculation of wet elasticity ratio is modified as described below in the section Test methods.

In such a specific embodiment, the activation web may be in the form of a polymeric network printed on a substrate (eg, a cellulose substrate) in a predetermined bond pattern to provide a plurality of textured, three-dimensional regions on the substrate. One embodiment of such an activation lane is generally in 4A as a train 200 shown. The train 200 includes a substrate 114 with a polymer printed thereon containing 110 is designated.

In this preferred embodiment, the adhesive is 110 on the substrate 114 applied by screen printing an adhesive in a grid pattern, as generally described in US Pat 4A is shown. A suitable screen for this embodiment is a four-mesh galvano screen manufactured by Rothtec Engraving Corp., New Bedford, MA. One suitable adhesive is a hot melt adhesive commercially available as H1382-01 from Ato-Findley Adhesives of Wauwatosa, Wisconsin. A suitable screen printer is available from ITW Dynatec, model SP-117.

The adhesive is preferably water-insoluble so that the printed structure retains its geometric integrity when wetted. The adhesive is preferably also tolerant to interfaces active substances. By "surfactant tolerant" is meant that the bonding characteristics of the adhesive is not degraded by the presence of surfactants. Suitable adhesives include EVA (ethylene vinyl acetate) based on hot melt adhesives.

With further reference to 3 the hot-melt adhesives can be applied to the substrate (eg the cellulose layer) 114 can be applied in a continuous network that limits a discontinuous plurality of unbound regions. In a preferred embodiment, as shown, the adhesive is applied as parallel, spaced-apart lines in a first direction, cut by parallel, spaced-apart lines in a second direction. The intersecting lines form diamond-shaped patterns of unbound regions in the activation lane.

E. Secondary tracks

The article of the present invention may also comprise one or more secondary webs. Webs or sheet materials useful in the present invention as secondary webs in conjunction with the activating web (such as that described in U.S. Pat 1 shown) to receive the multiphase multicomponent emulsion prior to use may take a variety of substrate forms. Suitable substrates include tissue materials, nonwoven materials, foams, sponges, wadding, beads, tuffs, films. Particularly preferred substrates for use in the present invention are nonwoven types. These nonwoven substrates may comprise any conventionally formed nonwoven web or web having suitable basis weight, caliper (thickness), absorbency and strength properties. Nonwoven substrates may generally be defined as bonded fibrous or filamentous products having a web structure in which the fibers or filaments are randomly distributed, such as by "air laying" or certain "wet-laying" processes, or with a degree of orientation, as in certain " wet-laying or carding processes. The fibers or filaments of such nonwoven substrates may be natural (eg wood pulp, wool, silk, jute, hemp, cotton, linen, sisal or ramie) or synthetic (eg rayon, cellulose esters, polyvinyl derivatives, polyolefins, polyamides or polyesters) and may be polymeric Bindeharz be interconnected. Examples of suitable commercially available nonwoven substrates include those sold under the brand name Sontara ^® from DuPont and Polyweb ^® by James River Corp. be marketed.

For reasons of cost, ease of manufacture and disposability of an article (eg, flushability), the preferred type of nonwoven substrate used in wipes of the present invention includes those made of wood pulp fibers, that is, paper webs. As noted, webs can be prepared by either air-laying or wet-laying techniques. Air-laid paper webs such as Air Tex ^® SCl30 are commercially available from James River Corp.

Yet conventional Paper webs are produced by wet-laying processes. In such processes, a web is made by adding a hydrous Papermaking material is formed, this substance deposited on a foraminous surface is, such as a Fourdrinier sieve, and then water is removed from the fabric, for example, by gravity through a vacuum assisted Drying and / or by evaporation, with or without a pressing process, to thereby obtain a paper web having the desired fiber consistency form. In many cases the papermaking apparatus is constructed so that the fibers in be rearranged to the pulp of papier mache when the drainage progress to paper substrates of particularly desirable Strength, handling, filling, Appearance, absorption capacity to build.

Of the Papermaking material used to form the preferred paper web substrates for articles of the present invention essentially comprises one an aqueous one Papermaking fiber pulp (ie, paper pulp) and can optionally contain a wide variety of chemicals, such as wet strength resins, surfactants Substances, pH regulators, softener additives, binders and the same. Wood pulp in all its variations can be used to form the papermaking material. Wood pulps, the useful here include sulphite and sulphate pulps as well as mechanical, thermome chanical and chemo-thermomechanical pulps, all well known to those skilled in papermaking technology are. It can Both pulps derived from deciduous and coniferous trees are used become. Preferably, the papermaking material used to become the preferred paper web substrates for wipes of the present invention to form a kraft pulp, derived from the northern softwoods becomes.

A number of papermaking processes have been developed which include a papermaking apparatus that makes paper webs with particularly useful or desirable fiber configurations. Such configurations can serve to impart such characteristics to the paper web, such as increased bulk, absorbency and strength. Such a method utilizes an imprinting material in the papermaking process which serves to introduce a bumpy pattern of high density, low density zones into the resulting paper web. A method of this type and the papermaking apparatus for carrying out this method is described in greater detail in U.S. Patent 3,301,746 (Sanford et al), published January 31, 1967.

One Another papermaking process uses a through-drying fabric with embossing bumps that over the Level of the substance are sublime. These impressions create protrusions in the throughdried fabrics and provide the sheet with a stretch in the cross machine direction. A method of this Type is described in European Patent Publication No. 677,612 A2, published on October 18, 1995 by G. Wendt et al.

Yet another papermaking process using a special papermaking apparatus accomplished is one that is a paper web of a distinct, continuous Network region, which is formed by a plurality of "vaults", the over distribute the network region on the substrate. Such bulges are formed by compressing an embryonic web, if this while the papermaking process in a foraminous Umbiegeelement with a patterned network surface formed which is defined by a plurality of discrete, isolated deflection channels in the surface the Umbiegeelements is formed. A method of this type and a device for performing of such a method is described in greater detail in FIG U.S. Patent 4,529,480 (Trokhan), issued July 16, 1985; U.S. Patent 4,637,859 (Trokhan), issued January 20, 1987 and U.S. Patent 5,073,235 (Trokhan), issued December 17 1991. Another type of papermaking process and a Device for performing same, which is suitable for the production of layered composite paper substrates, is described in US Patent 3,994,771 (Morgan et al.) on November 30, 1976.

Yet another papermaking process carried out with a particular papermaking apparatus is one which provides a paper web having regions of different basis weight. Such a process is described in US Patent 5,245,025, issued September 14, 1993 to Trokhan et al., US Patent No. 5,503,715, issued April 2, 1996 to Trokhan et al. and U.S. Patent No. 5,534,326, issued July 9, 1996 to Trokhan et al. See also the co-pending US patent US 6,133,166 , by Nissing et al. on July 1, 1997. Such substrates provide a carrier having regions which are more permeable (i.e., regions of relatively lower basis weight) than other regions (that is, regions of higher basis weight).

In addition to The papermaking fibers can be the papermaking material used for this purpose is to produce these paper web substrates, other components or contain materials therein as in the prior art can be known or later becomes known. The types of additives that are desirable will be dependent the specific end use of the considered tissue sheet. To the Example is in wipe products, such as toilet paper, paper towels, facial tissues, Baby wipes and other similar Products, high wet strength a desirable attribute. So it is common desirable, to add chemical substances to the papermaking material, the are known in the art as "wet strength" resins.

A general publication on types of wet strength resins used in paper technology can be found in TAPPI Monograph Serial No. 29, "Wet Strength in Paper and Paperboard", Technical Association of the Pulp and Paper Industry (New York, 1965 ). The most useful wet strength resins were generally cationic in nature. For permanent wet strength production, polyamide-epichlorohydrin resins are cationic wet strength resins which have been found to be particularly useful. Suitable types of such resins are described in US Patent No. 3,700,623 (Keim), issued October 24, 1972 and US Patent 3,772,076 (Keim), published October 13, 1973. A commercially available source of useful polyamide-epichlorohydrin resin is Hercules, Inc. of Wilmington, Delaware, that such resins marketed under the trademark Kymene ^® 557H.

Polyacrylamide resins have turned out to be useful wet strength resins. These resins are described in U.S. Patent Nos. 3,556,932 (Coscia et al.), Published January 19, 1971 and 3,556,933 (Williams et al.), Published January 19, 1971. An economical source of polyacrylamide resins is American Cyanamid Co. of Stamford, Connecticut, which markets one such resin under the mark Parez ^® 631 NC.

Yet further water-soluble Cationic resins which find application as wet strength resins are Urea formaldehyde and melamine formaldehyde resins. The more usual functional groups of these polyfunctional resins are nitrogen containing groups, such as amino groups and methylol groups, the Nitrogen attached are. Polyethyleneimine resins can also find application in the present invention. In addition, temporary wet-strength Resins such as Caldas 10 (manufactured by Japan Carlit), CoBond 1000 (manufactured by National Starch and Chemical Company) and Parez 750 (manufactured by American Cyanamid Co.) in the before lying Invention can be used. It is to be understood that the addition of chemical compounds, such as the wet-strength and temporary wet-strength Resins, as described above, to the pulp optionally is and is not necessary for the practice of the present invention.

In addition to It may also be desirable for the wet-strength additives to be certain in the papermaking fibers to include dry-fast and lint-regulating additives that are used in the State of the art are known. In this regard, starch binders have turned out to be particularly suitable. In addition to being a linting of the paper substrate lend small amounts of starch binders a moderate improvement in dry tensile strength, without stiffness confer on the addition of high levels of starch could. Typically, the starch binder in an amount such that it is based on a proportion of 0.01 to 2 wt.%, Preferably from 0.1 to 1 wt.% Of the paper substrate is held.

in the Generally, suitable starch binders for this Paper web substrates characterized by water solubility and hydrophilicity. Even though is not provided, the scope of suitable starch binder restrict, include representative starch materials corn starch and potato starch, with waxy corn starch, the industrially as Amioca starch is known, is particularly preferred. Amioca starch is different from conventional corn starch Going to make this complete consists of amylopectin, while general cornstarch contains both amylopectin and amylose. Different unique Properties of Amioca starch are further described in "Amioca - The Starch From Waxy Corn ", H. H. Schopmeyer, Food Industries, December 1945, pages 106-108 (Vol. Pages 1476-1478).

Of the starch binders may be in particulate form or in dispersed form, wherein the particulate form is particularly preferred. The starch binder is preferably sufficiently digested so that swelling the particle is induced. The most preferred are the starch particles, for example, by a cooking process, to a point short swollen prior to dispersion of the starch granules. Such strongly swollen starch granules are said to be to be called "fully cooked". The conditions for a dispersion in general can dependent on the size of the starch granules, the degree of crystallinity the granules and the amount of amylose present. Fully cooked amioca starch can prepared, for example Become an aqueous Broad of starch granules with about 4% consistency at about 190 ° F (about 88 ° C) is heated between about 30 and about 40 minutes. Further exemplary Starch binder, which can be used include modified cationic starches such as those modified to contain nitrogen-containing groups, including amino groups and methyl groups attached to nitrogen, available from National Starch and Chemical Company (Bridgewater, NJ), already earlier used as pulp additives to provide wet and / or dry strength to increase.

F. Other optional wiper components

Next the inverse emulsion with strong inner phase, there are more optional components included in the articles of the present invention can be included typically for the purpose of improving the cleaning performance of the article, when the inner polar phase of the emulsion is released. Certain of these optional components in the emulsion may not be present in significant proportions (e.g. of more than 2% of the inner polar phase), because they are early destruction can cause the emulsion. These include various anionic detergent surfactants Substances that have relatively high HLB values have (e.g., HLB's of 10 to 25), such as linear sodium alkylbenzenesulfonates (LAS) or alkyl ethoxy sulfates (AES) as well as non-ionic detergents surfactants Substances such as alkyl ethoxylates, alkyl amine oxides, alkyl polyglycosides, zwitterionic detergents surfactants, ampholytic detergent surface-active Substances and cationic detergents surfactants, such as cetyltrimethylammonium salts and lauryltrimethylammonium salts.

See US Patent 4,597,898 (Van der Meer), published July 1, 1986, especially columns 12-16 for respective anionic, nonionic, zwitterionic, ampholytic and cationic detergent surfactants. Instead, these high HLB detergent surfactants may be applied or incorporated separately from the emulsion in the article. For example, an aq emulsion of these high HLB detergent surfactants are applied to one side of the support substrate with the high internal phase inverse emulsion applied to the other side of the substrate. During wiping, the emulsion is disrupted, releasing the internal polar phase (eg, water) so that it is then combined with the high HLB detergent surfactant to provide improved hard surface cleaning.

Even though the description of the invention generally refers to a single Apply emulsion to the carrier, It can be seen that two or more different emulsions when preparing a single article can be used. In such embodiments can the emulsions differ in very different ways, including, but not limited on it, in proportion the inner polar phase to the outer lipids Phase, the emulsifiers used, the components used for the inner or for the lipid phase can be used and the like. Use of several Emulsions in an article can especially desirable when two or more components are incompatible with each other, but each may be contained in separate emulsions. alternative can, if a special reaction at the time of use is desired, the reactants may be provided in separate emulsions. At the Shearing the emulsion during the usage becomes the desired Reaction occur. For example, if foaming occurs during the wiping he wishes is a mild acid be incorporated in the inner polar phase of an emulsion while bicarbonate is incorporated in the inner polar phase of a second emulsion. During shearing of the emulsions during the use of the reactants interact and produce the desired Foam.

G. Other embodiments of cleaning articles

In addition to the in 1 As shown, cleaning articles in accordance with the present invention may be assembled in a variety of other alternative configurations while retaining the advantages of the present invention.

3 shows such an alternative configuration in which the cleaning article 1 in its structure is similar to that in 1 is shown, but in which the activation lane 2 itself forms an outer surface of the article. In such a configuration, if the activating sheet is liquid pervious, the article may look like the formed film web 2 , function as a two-sided cleaning article, and the active emulsion either through the activation lane or through the secondary lane 3 pass through. Alternatively, if the activating sheet is liquid-impermeable, the article functions as a one-sided cleaning article by delivering an active emulsion only through the secondary web.

H. Test Procedure - Wet Elasticity

A Wet resiliency (this means, The relationship from wet thickness to dry thickness) of an activation web measured using an electronic thickness tester model II of Thwing-Albert Instrument Co. according to the following procedure. The samples are heated at 70 ° F (21 ° C) and 50% relative humidity for conditioned two hours before the test.

The dry thickness of the activating sheet is measured using a limit pressure of 95 g / in ² (14.7 g / cm ² ) and a load foot with a diameter of 2 in (5 cm). The dry thickness is measured for eight samples. The eight thickness measurements are averaged to obtain a mean dry density.

each The sample is then wetted by placing the sample in a distilled bath Water for Immersed for 30 seconds. The sample is then removed from the water bath taken and allowed for Expire 5 seconds while she hung vertically is. The thickness of the wet sample will decrease within 30 seconds the sample is taken from the bath. The wet thickness will measured at the same place, at which the dry thickness before was measured. The eight wet thickness measurement are averaged to obtain a medium wet thickness. Of the relationship wet thickness to dry thickness is the average wet thickness, divided by the mean dry thickness.

Für diese Messung sei klar, dass eine Komponente der zusammengesetzten Bahn entfernt werde muss, um eine Messung von b, B; c, C oder beiden Werten unabhängig zu erleichtern.If the activation lane is a composite of several layers or materials, it will be necessary for the purpose of this measurement to calculate the elasticity ratio of the individual components. For the purposes of this calculation, the following definitions apply:

in which the elasticity ratio is defined as A / a; and in which it is believed that a, A and either b, B or c, C can be measured. For this measurement, it is clear that a component of the composite web must be removed to obtain a measurement of b, B; c, C or both values independently.

If a component of the composite web can not be measured after being removed from the composite, the elastic ratio can be calculated using the following expressions: B / b = (A-C) / (a-c) C / c = (A-B) / (a-b)

I. preparation of representative cleaning Supplies

At the Prepare the article according to the present Invention is initially the inverse emulsion with strong inner Phase formulated. Typically, this is achieved by using the lipid phase components and the emulsifier is blended or fused together. The special temperature to which this lipid / emulsifier mixture is heated, becomes dependent its from the melting point of the lipid phase components. typically, becomes this lipid / emulsifier mixture heated to a temperature range of 60 ° to 90 ° C, preferably from 70 ° to 80 ° C, before mixing, blending or otherwise with the polar ones Phase components is combined. The molten lipid / emulsifier mixture is then mixed with the polar inner phase components and then mixed together and typically under low shear conditions, to provide the emulsion.

The Inverse emulsion with strong internal phase is then in a liquid or plastic state at the above temperatures on the carrier substrate applied, for example on a paper web. Any variety of procedures, the materials with a liquid or plastic consistency can use be used to apply this emulsion. Suitable methods include spraying, Printing (e.g., flexographic or screen printing), coating (e.g., gravure coating), extrusion or combination these application techniques, for example, spraying the detergent surfactants Stoffes on a paper web, followed by a gravure coating the emulsion on the detergent-treated web.

The Emulsion can either be on one side or on both sides of the carrier web be applied or, in the case of multilayer webs, can on applied the one or more inner surfaces of the layers become. Once the emulsion has been applied to the carrier web is allowed to cool and a solidified, typically discontinuous coating or Film on the surface form the track.

The Inverse emulsion with strong internal phase is typically on the carrier web applied after the web has been dried, that is, it is a "dry run" addition process, for railways, which initially are wet-shaped. The emulsion can also be uneven the one or more surfaces be applied to the web. By "nonuniform" is meant that the set, the pattern of Distribution, etc. of the emulsion over the surface the carrier web can vary. For example, you can some areas of the surface the carrier web larger or have lower levels of the emulsion, including areas of the surface that do not wear emulsion.

The Inverse emulsion with strong inner phase may be on the carrier web Be applied at any time after being dried is. For example, the emulsion may be applied to the surface of a paper web be applied after being creped from a Yankee dryer has been. Usually will preferred to apply the emulsion to the carrier web when it is handled by a mother role and before it is minor Finished product rolls is wound up.

In applying the high internal phase inverse emulsions of the present invention Carrier webs are currently preferred spray coating methods. 5 shows such a process in which the emulsion is applied to a carrier web 10 is sprayed on. Regarding 5 This spray system has a spray head 12 containing a dispersed beam 14 the emulsion on the web 10 applies.

This spray system is actuated by an assembly consisting of a ball screw drive 16 that passes through a clutch 18 with a piston 26 a hydraulic cylinder 22 connected is. A part of the cylinder 22 is in 5 shown to be filled with inverse high internal phase emulsion, as with 30 is specified. The cylinder 22 is heated to the emulsion 30 to keep in a liquid or plastic state. The emulsion 30 enters the cylinder 22 via a four-way clutch 34 one with a lead 38 with a heated filling connection 42 connected is. The coupling 34 also has a lead 46 using a pressure gauge 50 and a spray head 12 connected is. There are three valves with 56 . 58 and 60 indicating the flow of emulsion in the pipes 38 and 46 regulate. The spraying system in 5 shown also has a lead 64 that with a spray head 12 connected to a general with 68 designated air allowed to be delivered to the spray head. The administration 64 also has a pressure gauge and a regulator 72 for controlling and measuring the air pressure in the pipe 64 and 46 are heated to keep the emulsion in a molten state prior to application to the web.

To the cylinder 22 with the emulsion 30 to fill, the valves are 56 and 60 closed and becomes the valve 58 open. The ball screw drive 16 is pressed, so that the piston 26 moved to the left. That in the cylinder 22 vacuum generated draws the emulsion from the filling port 42 through the pipe 38 and in the cylinder 22 , To the emulsion from the cylinder 22 to the spray head 12 to deliver, becomes the valve 58 closed and become the valves 56 and 60 open. The ball screw drive 16 is pressed, so that the piston 26 moved to the right. This pushes the emulsion 70 out of the cylinder 22 and the line 46 the clutch 34 , The emulsion then passes through the valve 60 through and into the spray head 12 into it, where it is through an intake with air from the pipe 64 is dispersed, so that the dispersed beam 14 is generated, which then on the web 10 is applied.

6 Figure 4 shows an alternative method of applying the high internal phase inverse emulsion comprising a rotogravure coating system. Regarding 6 becomes the carrier web 110 from the mother role 112 unwound (turning in the direction indicated by an arrow 112a is specified), and to turn rolls 114 . 116 and 118 advanced. From the revolving role 118 will be the train 110 advanced to a gravure station, which generally with 120 where the emulsion is then applied to both sides of the web. After leaving the station 120 will be the train 110 to a treated web with 122 is specified. The treated track 122 becomes a surface take-up roll 126 advanced (turning in the direction indicated by an arrow 126a is specified) and then on a finished product roll 128 wound up (turning in the direction indicated by arrow 128a is specified.

The station 120 includes a pair of heated, connected gravure presses 130 and 134 , The press 130 consists of a smaller anilox cylinder 138 and a larger pressure plate cylinder 142 ; the press 134 also consists of a smaller anilox cylinder 146 and a larger pressure plate cylinder 150 , The anilox cylinder 138 and 146 each have a ceramic or chrome surface while the printing plate cylinders 142 and 150 each have a textured rubber, urethane or photopolymer surface. These anilox and plate cylinders rotate in the directions indicated by the arrows 138a . 142a . 146a respectively. 150a are indicated. As in 6 is shown, lie the printing plate cylinder 142 and 150 face each other and ensure a gap area through 154 indicated by which the railway 110 passes through.

The hot, melted (eg 60 ° C) emulsion is applied to each of these bonded gravure presses 130 and 134 pumped or sprayed at the nip area as indicated by the arrows 158 respectively. 162 is given, in a constant volu metric flow rate. (The presses 130 and 134 delivered emulsion may be the same or different.) In other words, the emulsion is applied to the connected gravure presses 130 and 134 delivered at the same rate as the emulsion on the web 110 is applied. This prevents "build-up" of the emulsion in the system. Because anilox cylinder 138 and 146 turn in the directions indicated by the arrows 138a and 146a As shown, they act as rotary coating blades to uniformly apply the emulsions across the surfaces of the printing plate cylinders 142 respectively. 150 to distribute and excess emulsion from the pressure plates of the cylinder 142 and 150 to remove.

The emulsion applied to the printing plate cylinder 142 and 150 is distributed (turning in the opposite direction, as indicated by the arrows 142a and 150b is specified), then on both sides of the web 110 at the gap area 154 transfer. The amount of the train 110 transferred emulsion can be regulated by: ( 1 ) Adjust the width of the gap area 154 between the printing plate cylinders 142 and 150 ; ( 2 ) Adjust the width of the gap areas 158 and 162 between anilox / printing plate cylinder pairs 138 / 142 and 146 / 150 ; ( 3 ) the print image profile (that is, the valley depth) of the printing plate on the cylinder 142 and 150 ; ( 4 ) the pressure area (that is, the valley area) of the pressure plate on the cylinders 142 and 150 ; and or ( 6 ) the printing pattern of the printing plate on the cylinders 142 and 150 ,
