Description
SURFACE CLEANING PAD HAVING ZONED ABSORBENCY AND METHOD OF MAKING
SAME
FIELD OF THE INVENTION
The present invention relates to an absorbent surface cleaning pad, such as a floor cleaning pad, and to a method for fabricating the surface cleaning pad in such a way as to provide zoned absorbency.
BACKGROUND OF THE INVENTION
Conventional floor mops comprise a handle rotatably connected to a mop head and a disposable absorbent cleaning sheet coupled to the mop head.
One side of the disposable absorbent cleaning sheet is placed in direct contact with a surface to be cleaned and the opposing side of the cleaning sheet is coupled to the mop head. The cleaning sheet absorbs and retains fluids, and loosens and traps dirt particles on the cleaning surface.
The cleaning sheet may comprise an absorbent portion that includes superabsorbent polymer (SAP) particles. The SAP particles can escape from the absorbent portion during manufacture, shipment, and normal use conditions.
This phenomenon is commonly referred to as particle shake-out. A reduction in the amount or volume of SAP particles within the cleaning sheet hinders the performance and decreases the absorbency rating of the cleaning sheet.

The present invention relates to an absorbent surface cleaning pad, such as a floor cleaning pad, and to a method for fabricating the surface cleaning pad in such a way as to provide zoned absorbency.
BACKGROUND OF THE INVENTION
Conventional floor mops comprise a handle rotatably connected to a mop head and a disposable absorbent cleaning sheet coupled to the mop head.
One side of the disposable absorbent cleaning sheet is placed in direct contact with a surface to be cleaned and the opposing side of the cleaning sheet is coupled to the mop head. The cleaning sheet absorbs and retains fluids, and loosens and traps dirt particles on the cleaning surface.
The cleaning sheet may comprise an absorbent portion that includes superabsorbent polymer (SAP) particles. The SAP particles can escape from the absorbent portion during manufacture, shipment, and normal use conditions.
This phenomenon is commonly referred to as particle shake-out. A reduction in the amount or volume of SAP particles within the cleaning sheet hinders the performance and decreases the absorbency rating of the cleaning sheet.
Attempts have been made to overcome this problem in other fields such as the field of baby diapers, adult incontinence products, sanitary napkins and the like.
For example, an absorbent structure for such products is disclosed in U.S. Patent 6,562,742, which illustrates a diaper absorbent body with SAP particles placed in discrete locations or zones within the structure. According to U.S. Patent 6,562,742, superabsorbent polymer particles are placed in at least one strata of an upper ply in longitudinal discrete lanes along the length of the core, and the lanes are separated by adjacent lanes including fibers and a binder. Such a discrete placement of SAP particles is disclosed to allow for better containment of the particles, facilitate flow of liquid in the Z-direction because of the presence of areas with little or no SAP, and allow for easier flow and wicking of the fluid along the length of the core (x-direction). The areas with little or no SAP particles may be additionally densified to improve integrity and create higher capillary tension within smaller pores.
Nevertheless, there continues to be a need for an improved absorbent cleaning pad, such as a floor cleaning pad, and an improved method for fabricating the cleaning pad in such a way as to provide zoned absorbency.

DETAILED DESCRIPTION OF THE INVENTION
5 Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown.
Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the invention. Also, the embodiments selected for illustration in the figures are not shown to scale and are not limited to the proportions lo shown.
As used herein, the term "superabsorbent polymer (SAP) particle" refers to any absorbent material having a gig capacity for water of at least about 20 gig, when measured under a confining pressure of 0.3 psi. Non-limiting examples of suitable superabsorbent Referring to the overall structure of one exemplary embodiment, Figures 1-4 illustrate an absorbent cleaning pad designated generally by the numeral "110". Generally, the absorbent cleaning pad 110 has a pad body formed from an airlaid composite and having positioned facing, or attached to, a cleaning implement. The surface cleaning pad also has a barrier adhered to and substantially covering the opposite surface of the pad body and a pair of scrubbing members adhered to the cleansing surface of the pad body.
More specifically, the exemplary absorbent cleaning pad (or sheet) 110 is provided with an airlaid composite 120. Two folded dirt entrapment members 125 are adhered to a cleaning side 152 of the airlaid composite 120 by an adhesive 130 and extend along the length of the airlaid composite 120. A
barrier layer 140 is adhered to an opposing attachment side 155 of the airlaid composite 120 and is folded around the width-wise sides 124 of the airlaid composite 120, thereby enclosing the width-wise sides 124 of the airlaid composite 120. Two attachment members 145 are adhered to the barrier layer 140 by an adhesive 130.
The airlaid composite 120 of the exemplary embodiment absorbs and retains fluids and/or other matter residing on a cleaning surface. The cleaning side 152 of the cleaning pad 110 is in direct contact with the floor surface, and the opposing attachment side 155 of the absorbent cleaning pad 110 is in contact with a cleaning implement such as a mop head (not shown). The dirt entrapment members 125 serve to facilitate the removal of soils from the surface being cleaned by contacting and trapping larger soil particles. The barrier layer 140 substantially prevents fluid from passing from the airlaid composite 120 to the cleaning implement, to keep the cleaning implement substantially free of fluid. The barrier layer 140 also substantially prevents absorbent particles within the airlaid composite 120 from escaping out of the exposed width-wise sides 124 of the airlaid composite 120.

As used herein, the term "superabsorbent polymer (SAP) particle" refers to any absorbent material having a gig capacity for water of at least about 20 gig, when measured under a confining pressure of 0.3 psi. Non-limiting examples of suitable superabsorbent Referring to the overall structure of one exemplary embodiment, Figures 1-4 illustrate an absorbent cleaning pad designated generally by the numeral "110". Generally, the absorbent cleaning pad 110 has a pad body formed from an airlaid composite and having positioned facing, or attached to, a cleaning implement. The surface cleaning pad also has a barrier adhered to and substantially covering the opposite surface of the pad body and a pair of scrubbing members adhered to the cleansing surface of the pad body.
More specifically, the exemplary absorbent cleaning pad (or sheet) 110 is provided with an airlaid composite 120. Two folded dirt entrapment members 125 are adhered to a cleaning side 152 of the airlaid composite 120 by an adhesive 130 and extend along the length of the airlaid composite 120. A

Two attachment members 145 are adhered to the barrier layer 140 by an adhesive 130.
The airlaid composite 120 of the exemplary embodiment absorbs and retains fluids and/or other matter residing on a cleaning surface. The cleaning side 152 of the cleaning pad 110 is in direct contact with the floor surface, and the opposing attachment side 155 of the absorbent cleaning pad 110 is in contact with a cleaning implement such as a mop head (not shown). The dirt entrapment members 125 serve to facilitate the removal of soils from the surface being cleaned by contacting and trapping larger soil particles. The barrier layer 140 substantially prevents fluid from passing from the airlaid composite 120 to the cleaning implement, to keep the cleaning implement substantially free of fluid. The barrier layer 140 also substantially prevents absorbent particles within the airlaid composite 120 from escaping out of the exposed width-wise sides 124 of the airlaid composite 120.
. .
The attachment members 145 provide a single attachment mechanism that can be used to temporarily couple the absorbent cleaning pad 110 to a cleaning implement such as a mop head. In this exemplary embodiment, the attachment members 145 are composed of loop fastening material available from Velcro USA Inc. of Manchester, N.H., USA.
The exemplary embodiment of the absorbent cleaning pad 110 comprises a unitized airlaid composite 120 having an absorbent core composed of at least binder fibers, absorbent fibers and superabsorbent polymer (SAP) particles 150. The absorbent core should be of sufficient integrity to ensure that the absorbent core does not deform and 3.0 exhibit discontinuities during its normal use in cleansing a surface.
The SAP particles 150 provide the airlaid composite 120 with increased absorbency, while the binder and absorbent fibers form the overall structure of the airlaid composite 120. In this embodiment, the binder fibers are optionally bi-component fibers and the absorbent fibers are optionally cellulosic fibers.
The absorbency portion of the airlaid composite 120 may optionally be composed of pulp fibers, rayon fibers, superabsorbent fibers, a combination of superabsorbent and pulp fibers, a combination of superabsorbent and rayon fibers, a combination of pulp, superabsorbent and rayon fibers, a non-woven web and a in-situ (liquid) superabsorbent, a tissue and in-situ (liquid) superabsorbent, a pulp and in-situ (liquid) superabsorbent, rayon fibers and a in-situ (liquid) superabsorbent, pulp, rayon fibers and a in-situ (liquid) superabsorbent, or a combination thereof of any of the above. The absorbent core component is an essentially hydrophilic material capable of absorbing and retaining fluids.
The absorbent component may be composed of fibers, powders, and polymeric binders, any of which may be natural or synthetic. .
The exposed sides of the airlaid composite 120 may be sealed or covered to substantially limit the SAP particles 150 from escaping out of the exposed sides of the airlaid composite 120. According to exemplary embodiments of this invention, however, to prevent the escapement of the SAP particles 150, the SAP particles may be concentrated or zoned an adequate distance away from one or more of the exposed sides of the airlaid composite 120.
The matrix web of binder fibers would substantially inhibit the zoned SAP
particles from migrating a significant distance toward the exposed sides of the airlaid composite 120. An example of a zoned SAP region is illustrated in Figure 1.
In addition to airlaid composites, other absorbent pad body materials, structures and/or processes are contemplated as well. For example, in another exemplary embodiment, an absorbent core prepared by expanding a polymer tow is also contemplated for use as an absorbent pad. In one exemplary embodiment, the absorbent core comprises a plurality of filaments in the form of an expanded tow, and a layer comprising a liquid superabsorbent material on surfaces of the filaments. The liquid superabsorbent polymer may be applied to the expanded tow, for example, by spraying or by application using a gravure roller. In this embodiment, the liquid superabsorbent polymer is applied to a portion(s) of the width and/or the length of the expanded tow.
Referring now to Figures 1-4, specifically Figure 1, the SAP particles 150 are dispersed in a discrete zone of the airlaid composite 120. The SAP
particles 150 are substantially concentrated in the center of the width of the airlaid composite 120 to substantially limit the SAP from escaping out of the open length-wise sides 123 of the airlaid composite 120. The discrete SAP zone 150 comprises the width "C", the length "B" and the thickness of the airlaid composite 120.
Although the SAP particle 150 zone is contiguous with the exposed width-wise sides 124 of the airlaid composite, the portion of the barrier layer folded over the width-wise sides 124 substantially prevents the escapement of SAP 150 out of the exposed width-wise sides 124.
The SAP particles 150 are also substantially prevented from escaping through the cleaning side 152 and the attachment side 155 of the airlaid composite. The dense web of binder fibers at the cleaning side 152 and the attachment side 155 of the airlaid composite substantially prevents the SAP
particles 150 from escaping. In addition, the barrier layer 140 substantially prevents the SAP particles 150 from escaping out of the attachment side 155 of the airlaid composite 120, as illustrated in Figure 4.
The exemplary embodiment provides several advantages. The zoned SAP particles reduce particle shake out, gel blocking, and manufacturing costs and promote efficient fluid absorption throughout the airlaid composite. SAP
particle shake-out hinders the performance of the cleaning pad and degrades the cleaning pad's absorbency rating. By virtue of the zoned SAP, the exemplary cleaning pad 110 can retain a greater number of SAP particles within the airlaid composite.
The discrete placement of SAP particles also facilitates the flow of fluid along the regions of the cleaning pad devoid of SAP particles. The regions without SAP particles promote flow and wicking of fluid along the entire length and width of the exemplary airlaid composite. Therefore, the discrete placement of SAP
particles promotes the utilization of the entire airlaid composite for absorption.
The discrete placement of SAP particles also substantially reduces gel blocking within the airlaid composite, thereby improving the cleaning pad's ability to absorb and retain fluid. Gel blocking leads to the inhibition of fluid flow throughout the entire airlaid composite, thereby reducing the absorbency rating of the cleaning pad. In other words, the airlaid composite cannot efficiently absorb fluid if too many SAP particles are positioned or concentrated on the cleaning surface of the airlaid composite, as the swelled SAP particles prevent the fluid from traveling in the z-direction (i.e., along the thickness of the airlaid composite). The discrete placement of SAP particles promotes uniform fluid absorption throughout the exemplary airlaid composite.
From the manufacturing perspective, by virtue of the SAP zone 150 illustrated in Figures 1-4, the barrier layer 140 does not have to be folded over the length-wise sides 123 of the airlaid composite 120, as there is no need to prevent SAP particles 150 from escaping out of the length-wise sides 123. The cleaning pad 110 therefore utilizes less barrier layer material and does not require the additional operation of folding the barrier layer over the length-wise sides 123 of the airlaid composite 120. This represents a cost savings to the manufacturer by way of reduced barrier layer material expense and labor or equipment expense.
Another exemplary embodiment of a cleaning pad 510 is illustrated in Figure 5a. The SAP particle zone 550 is provided in a central region of the airlaid composite 520, remote from the entire periphery of the airlaid composite 520. The SAP particle zone 550 may adopt any form, e.g. square as shown, circular, rectangular, semicircular, etc. The outline of the airlaid composite 520 is shown in dotted line form to indicate that the airlaid composite 520 has no boundaries and that the zone 550 can be provided in any desired shape or configuration. In other words, the length and width of the airlaid composite may be any dimension larger than the length "D" and width "E" of the superabsorbent particle 550 zone. For example, the airlaid composite 520 of the exemplary embodiment may be an individual cleaning pad or a continuous cleaning sheet composed of a plurality of cleaning pads.
By virtue of the zoned SAP 550, the barrier layer (not shown) of the exemplary embodiment illustrated in Figure 5a does not have to conceal or otherwise cover the exposed length-wise and width-wise sides of the airlaid composite 520 to prevent shake-out of SAP. The zoned SAP particles 550 cannot migrate to the periphery of the airlaid composite, assuming that there is an adequate gap between the SAP particle zone 550 and the periphery of the airlaid composite 520. By zoning the SAP particles away from the periphery of the airlaid composite 520, a material and assembly cost reduction may be realized, as additional barrier layer material does not have to cover the sides of the airlaid composite 520 and the barrier layer folding operations are eliminated.
The exemplary embodiment of the absorbent cleaning pad 110 comprises a unitized airlaid composite 120 having an absorbent core composed of at least binder fibers, absorbent fibers and superabsorbent polymer (SAP) particles 150. The absorbent core should be of sufficient integrity to ensure that the absorbent core does not deform and 3.0 exhibit discontinuities during its normal use in cleansing a surface.
The SAP particles 150 provide the airlaid composite 120 with increased absorbency, while the binder and absorbent fibers form the overall structure of the airlaid composite 120. In this embodiment, the binder fibers are optionally bi-component fibers and the absorbent fibers are optionally cellulosic fibers.
The absorbency portion of the airlaid composite 120 may optionally be composed of pulp fibers, rayon fibers, superabsorbent fibers, a combination of superabsorbent and pulp fibers, a combination of superabsorbent and rayon fibers, a combination of pulp, superabsorbent and rayon fibers, a non-woven web and a in-situ (liquid) superabsorbent, a tissue and in-situ (liquid) superabsorbent, a pulp and in-situ (liquid) superabsorbent, rayon fibers and a in-situ (liquid) superabsorbent, pulp, rayon fibers and a in-situ (liquid) superabsorbent, or a combination thereof of any of the above. The absorbent core component is an essentially hydrophilic material capable of absorbing and retaining fluids.
The absorbent component may be composed of fibers, powders, and polymeric binders, any of which may be natural or synthetic. .
The exposed sides of the airlaid composite 120 may be sealed or covered to substantially limit the SAP particles 150 from escaping out of the exposed sides of the airlaid composite 120. According to exemplary embodiments of this invention, however, to prevent the escapement of the SAP particles 150, the SAP particles may be concentrated or zoned an adequate distance away from one or more of the exposed sides of the airlaid composite 120.
The matrix web of binder fibers would substantially inhibit the zoned SAP
particles from migrating a significant distance toward the exposed sides of the airlaid composite 120. An example of a zoned SAP region is illustrated in Figure 1.
In addition to airlaid composites, other absorbent pad body materials, structures and/or processes are contemplated as well. For example, in another exemplary embodiment, an absorbent core prepared by expanding a polymer tow is also contemplated for use as an absorbent pad. In one exemplary embodiment, the absorbent core comprises a plurality of filaments in the form of an expanded tow, and a layer comprising a liquid superabsorbent material on surfaces of the filaments. The liquid superabsorbent polymer may be applied to the expanded tow, for example, by spraying or by application using a gravure roller. In this embodiment, the liquid superabsorbent polymer is applied to a portion(s) of the width and/or the length of the expanded tow.
Referring now to Figures 1-4, specifically Figure 1, the SAP particles 150 are dispersed in a discrete zone of the airlaid composite 120. The SAP
particles 150 are substantially concentrated in the center of the width of the airlaid composite 120 to substantially limit the SAP from escaping out of the open length-wise sides 123 of the airlaid composite 120. The discrete SAP zone 150 comprises the width "C", the length "B" and the thickness of the airlaid composite 120.
Although the SAP particle 150 zone is contiguous with the exposed width-wise sides 124 of the airlaid composite, the portion of the barrier layer folded over the width-wise sides 124 substantially prevents the escapement of SAP 150 out of the exposed width-wise sides 124.
The SAP particles 150 are also substantially prevented from escaping through the cleaning side 152 and the attachment side 155 of the airlaid composite. The dense web of binder fibers at the cleaning side 152 and the attachment side 155 of the airlaid composite substantially prevents the SAP
particles 150 from escaping. In addition, the barrier layer 140 substantially prevents the SAP particles 150 from escaping out of the attachment side 155 of the airlaid composite 120, as illustrated in Figure 4.
The exemplary embodiment provides several advantages. The zoned SAP particles reduce particle shake out, gel blocking, and manufacturing costs and promote efficient fluid absorption throughout the airlaid composite. SAP
particle shake-out hinders the performance of the cleaning pad and degrades the cleaning pad's absorbency rating. By virtue of the zoned SAP, the exemplary cleaning pad 110 can retain a greater number of SAP particles within the airlaid composite.
The discrete placement of SAP particles also facilitates the flow of fluid along the regions of the cleaning pad devoid of SAP particles. The regions without SAP particles promote flow and wicking of fluid along the entire length and width of the exemplary airlaid composite. Therefore, the discrete placement of SAP
particles promotes the utilization of the entire airlaid composite for absorption.
The discrete placement of SAP particles also substantially reduces gel blocking within the airlaid composite, thereby improving the cleaning pad's ability to absorb and retain fluid. Gel blocking leads to the inhibition of fluid flow throughout the entire airlaid composite, thereby reducing the absorbency rating of the cleaning pad. In other words, the airlaid composite cannot efficiently absorb fluid if too many SAP particles are positioned or concentrated on the cleaning surface of the airlaid composite, as the swelled SAP particles prevent the fluid from traveling in the z-direction (i.e., along the thickness of the airlaid composite). The discrete placement of SAP particles promotes uniform fluid absorption throughout the exemplary airlaid composite.
From the manufacturing perspective, by virtue of the SAP zone 150 illustrated in Figures 1-4, the barrier layer 140 does not have to be folded over the length-wise sides 123 of the airlaid composite 120, as there is no need to prevent SAP particles 150 from escaping out of the length-wise sides 123. The cleaning pad 110 therefore utilizes less barrier layer material and does not require the additional operation of folding the barrier layer over the length-wise sides 123 of the airlaid composite 120. This represents a cost savings to the manufacturer by way of reduced barrier layer material expense and labor or equipment expense.
Another exemplary embodiment of a cleaning pad 510 is illustrated in Figure 5a. The SAP particle zone 550 is provided in a central region of the airlaid composite 520, remote from the entire periphery of the airlaid composite 520. The SAP particle zone 550 may adopt any form, e.g. square as shown, circular, rectangular, semicircular, etc. The outline of the airlaid composite 520 is shown in dotted line form to indicate that the airlaid composite 520 has no boundaries and that the zone 550 can be provided in any desired shape or configuration. In other words, the length and width of the airlaid composite may be any dimension larger than the length "D" and width "E" of the superabsorbent particle 550 zone. For example, the airlaid composite 520 of the exemplary embodiment may be an individual cleaning pad or a continuous cleaning sheet composed of a plurality of cleaning pads.
By virtue of the zoned SAP 550, the barrier layer (not shown) of the exemplary embodiment illustrated in Figure 5a does not have to conceal or otherwise cover the exposed length-wise and width-wise sides of the airlaid composite 520 to prevent shake-out of SAP. The zoned SAP particles 550 cannot migrate to the periphery of the airlaid composite, assuming that there is an adequate gap between the SAP particle zone 550 and the periphery of the airlaid composite 520. By zoning the SAP particles away from the periphery of the airlaid composite 520, a material and assembly cost reduction may be realized, as additional barrier layer material does not have to cover the sides of the airlaid composite 520 and the barrier layer folding operations are eliminated.
Another exemplary embodiment of a cleaning pad 510 is illustrated in Figure 5b. Similar to the exemplary embodiment illustrated in Figure 1, the SAP
particle zone 550 extends along the entire length of the airlaid composite 520. The width-wise sides of the airlaid composite 520 are shown in dotted form to indicate that the length of the airlaid composite 520 is optionally continuous. This exemplary embodiment may optionally represent a continuous airlaid sheet that can be divided, by width-wise cutting or other parting operation, into a plurality of individual airlaid pads.
Another exemplary embodiment of a cleaning pad 510 is illustrated in Figure 5c. Similar to the exemplary embodiment illustrated in Figure 5b, the SAP zone 550 extends along the entire length of the airlaid composite 520.
This exemplary embodiment provides multiple zones of SAP particle 550 of width "G".
However, the width of the multiple zones of SAP may vary as well, depending upon the fluid distribution and fluid management. The discrete placement of the SAP
particle zones 550 facilitates the flow of fluid along the regions of the cleaning pad devoid of SAP particles. The regions without SAP particles promote flow and wicking of the fluid along the length and width of the cleaning pad and limit gel blocking.
Alternatively, the cleaning pad embodiment shown in Figure 5c is provided as an interim substrate or step in forming an absorbent cleaning pad.
For example, a method of forming cleaning pad bodies can include forming a substrate of fibers, and then depositing superabsorbent polymer particles to the substrate in zones extending along the substrate separated by one or more gaps extending along the substrate to form the interim cleaning pad substrate 510. The substrate 510 can then be cut or otherwise parted along one or more of the gaps to form substrate portions each having an edge portion substantially devoid of superabsorbent polymer particles. Such an interim substrate 510 can then be parted in a direction substantially perpendicular to the gaps to form cleaning pad bodies. In other words, the substrate 510 can be divided along the gaps between adjacent zones and then cut or parted in a direction substantially perpendicular to the gaps to form shorter lengths, thereby forming a structure corresponding to the absorbent composite 120 used in the absorbent cleaning pad 110 shown in Figures 1-4.
Figures 6 and 7 schematically show an example of an airlaid composite forming system 600 that can be used to form an absorbent cleaning pad according to one aspect of the invention if the pad includes an airlaid composite. It is also contemplated that the absorbent cleaning pad is formed with an alternative structure, including any fibrous or non-fibrous material capable of defining a substrate.
Although only one example of an airlaid composite forming system is illustrated, this invention is not limited to the particular airlaid composite forming system selected for illustration in the Figures, and this invention is not limited to an absorbent pad having an airlaid structure. Other airlaid forming systems and other pad-producing processes are contemplated as well.
The airlaid composite forming system 600 comprises a moving perforated forming wire 602, which acts as a conveyor, with forming head equipment mounted thereabove. In the orientation illustrated in Figures 6 and 7, the upper surface of the wire 602 moves from right to left at a rate appropriate for proper distribution of materials on the wire 602. Alternatively, the wire 602 can remain stationary while other equipment (e.g., forming heads) move respect to the wire 602. Nevertheless, a continuous conveyer process such as that illustrated in Figures 6 and 7 is advantageous.
Forming heads 604 and 606 each receives a flow of an air fluidized fiber material (e.g., binder fibers, wood pulp, other fibrous materials, or combination thereof) via supply channels 608. A suction source 614 mounted beneath the perforated moving wire 602, draws air downwardly through the perforated moving wire 602. In one embodiment, the binder fiber material is distributed and compacted (by the air flow) over the width of the wire 602 to form an light web layer on the surface of the wire 602. A second forming head (not shown) is provided to distribute a second web layer 616 composed of a mixture of binder fibers and cellulosic fibers onto the light web layer.
The SAP particles are introduced into the particle dispenser 620 through a tube 618. The particle dispenser 620 is configured to direct (e.g., spray, sprinkle, release, etc.) the SAP particles onto the perforated moving wire 602 above the web layer 616. The SAP particles are either distributed over a portion of the width and/or length of the web layer 616 or distributed over the entire web layer 616. The SAP particles blend and disseminate through the web layer 616 and are thereby maintained throughout the entire thickness of the airlaid composite.
A third forming head 606 is provided to distribute another web layer 622 of binder and/or cellulosic fibers over the SAP particles. Although only two forming heads are illustrated, more forming heads may be required to distribute additional layers of binder fiber or cellulosic fiber. Thereafter, the web layers are heated for a period of time until the binder fibers melt together to form a web-like structure, i.e., an airlaid composite.
particle zone 550 extends along the entire length of the airlaid composite 520. The width-wise sides of the airlaid composite 520 are shown in dotted form to indicate that the length of the airlaid composite 520 is optionally continuous. This exemplary embodiment may optionally represent a continuous airlaid sheet that can be divided, by width-wise cutting or other parting operation, into a plurality of individual airlaid pads.
Another exemplary embodiment of a cleaning pad 510 is illustrated in Figure 5c. Similar to the exemplary embodiment illustrated in Figure 5b, the SAP zone 550 extends along the entire length of the airlaid composite 520.
This exemplary embodiment provides multiple zones of SAP particle 550 of width "G".
However, the width of the multiple zones of SAP may vary as well, depending upon the fluid distribution and fluid management. The discrete placement of the SAP
particle zones 550 facilitates the flow of fluid along the regions of the cleaning pad devoid of SAP particles. The regions without SAP particles promote flow and wicking of the fluid along the length and width of the cleaning pad and limit gel blocking.
Alternatively, the cleaning pad embodiment shown in Figure 5c is provided as an interim substrate or step in forming an absorbent cleaning pad.

Such an interim substrate 510 can then be parted in a direction substantially perpendicular to the gaps to form cleaning pad bodies. In other words, the substrate 510 can be divided along the gaps between adjacent zones and then cut or parted in a direction substantially perpendicular to the gaps to form shorter lengths, thereby forming a structure corresponding to the absorbent composite 120 used in the absorbent cleaning pad 110 shown in Figures 1-4.

A third forming head 606 is provided to distribute another web layer 622 of binder and/or cellulosic fibers over the SAP particles. Although only two forming heads are illustrated, more forming heads may be required to distribute additional layers of binder fiber or cellulosic fiber. Thereafter, the web layers are heated for a period of time until the binder fibers melt together to form a web-like structure, i.e., an airlaid composite.
In functional terms, the first light web layer including binder fibers is oriented toward the cleaning surface and provides structure to the airlaid composite. The second web layer 616 including binder fibers and cellulosic fibers is maintained over the first light web layer and provides structure and absorbency to the airlaid composite. The SAP particles are maintained over the second web layer 616 to provide additional absorbency to the airlaid composite. The third web layer 622 including binder fibers and cellulosic fibers are maintained over the SAP
particles and is oriented toward the cleaning implement. The third web layer provides structure and absorbency to the airlaid composite. The web layers collectively form an airlaid composite according to one embodiment.
Although not shown, in yet another exemplary embodiment, a preformed sheet comprising SAP particles may be positioned above the light web layer 616, as an alternative to using the particle dispenser 620. The preformed sheet may be of any size equal to or smaller than the light web layer 616.

particles to a zone of length "D" and width "E" above the web layer 616 to form a single airlaid composite. To form a continuous sheet composed of multiple airlaid composites 520, the particle dispenser 620 is configured to periodically distribute the SAP in zones onto the moving web layer 616. A processing unit (not shown) controls the operation of the particle dispenser 620 and the duration of each SAP
distribution period. The duration of each SAP distribution period is dependent upon the speed of the moving wire 602, the length of each individual airlaid composite and the length of the SAP particle zone.

particles and binder fibers are both introduced into tube 618 of the particle dispenser 620.
The particle dispenser 620 therefore distributes both SAP particles and binder fibers over a zone of length "D" and width "E" over the web layer 616. However, it should be understood that the particle dispenser 620 and the forming heads 604 and 606 can distribute any type of fiber or particle or combination thereof, as the dispenser and forming heads are not limited to merely distributing binder fibers and SAP particles.
