On the other hand, the present invention relates to be used for the preferably disposable cleaning foil of cleaning hard surfaces, described cleaning foil comprises functional cuffs, preferably free-swimming double-deck ring-type functional cuffs.

In the process of exploitation cleaning pad of the present invention and cleaning foil, the applicant finds that an importance of clean-up performance provides a such cleaning pad, this cleaning pad has multiple aperture film, the permeable subsidiary layer of liquid, and/or have density gradient, and/or have functional cuffs and the cleaning foil that functional cuffs is arranged.Under typical clean operation condition (promptly, cleaning pad and/or cleaning foil with they the y direction or the parallel direction of width on moved to and fro), each parts separately still works independently or is used in combination with other one or more parts and the clean-up performance of improvement is provided all for cleaning pad and/or cleaning foil.The multiple aperture formed film is preferred for scrubbing layer, can allow liquid transfer to other layer of cleaning pad effectively from surface to be cleaned by also making liquid, preferably can arrive one or more absorbed layers, to reduce the tendency that this liquid is stressed go back to surface to be cleaned.Functional cuffs is preferably free-swimming, make its can be on the y direction during typical cleaning operation " upset " back and forth, thereby can catch particulate matter and reduce the tendency that these particulate matters deposit to surface to be cleaned again.Density gradient is preferably introduced on the absorbed layer of cleaning pad to make lip-deep liquid to be cleaned be transported on the cleaning pad zone further from surface to be cleaned by " suction " or " capillarity ".Liquid-tight subsidiary layer provides a barrier, and it better is dispersed on the x-y direction liquid when the cleaning pad rear portion that arrives away from cleaning surface.These aspects of the present invention and the advantage that is proposed go through in conjunction with the accompanying drawings.

The technical staff will appreciate that and can use different raw materials to realize the present invention.Therefore, though the preferred material of different cleaning apparatus, pad and wafer assemblies is described below, we think that scope of the present invention is not limited to these descriptions.

Have been found that with density gradient be combined in unite use with the present invention the whole absorbed layer of cleaning pad to clean-up performance and cleaning pad fast Absorption liquid, comprise that especially the ability of the liquid of particulate matter has material impact.Though density gradient has been used for resembling absorbent articles such as diaper, sanitary napkin, incontinence article, the applicant finds that the concrete density gradient that is used for the cleaning pad absorbed layer has unique effectiveness.The uniqueness of cleaning pad density gradient has following two identifiable reasons at least: the first, and the absorbed layer of cleaning pad need be handled and contain soluble and insoluble component, and suspending components, as the water of undissolved particulate matter.With regard to diaper, sanitary napkin, incontinence article etc., absorbed layer obviously only needs to handle the liquid that contains soluble constituent, as body fluid.The second, the absorbed layer of cleaning pad need overcome gravity and absorb liquid.With regard to diaper, sanitary napkin, incontinence article etc., the absorbed layer typical case utilizes gravity that liquid is sucked, and makes it to be distributed in whole absorbed layer.It is very important that cleaning is lined with enough elastic force, and as described below, enough elastic force can be kept clean-up performance preferably, especially in comprising the cleaning pad of density gradient.The preferred cleaning pad that comprises concrete density gradient described herein, its improvement shows the importance of at least three influences to the clean-up performance of hard surface: infiltration rate (liquid is transferred to the required time of cleaning pad absorbed layer from surface to be cleaned); Dispersibility (for making full use of cleaning pad, absorbed layer is to the wicking capacity of liquid); Wetting power (amount that keep in the absorbed layer and the addle that in cleaning process, can not be squeezed out) again.

On the z of cleaning pad direction, absorbed layer can comprise a single absorbed layer with gradient of continuous density, thereby or has a multi-layer absorber layer that different density causes density gradient.Continuous density gradient is meant that the material that comprises cleaning pad is a homogeneous, but the density difference in whole material.Continuous density gradient preparation method is disclosed in the United States Patent (USP) 4,818,315 of authorizing people such as Hellgren on April 4th, 1989, and this patent is incorporated herein by reference.Preferably, the cleaning pad that uses in conjunction with the present invention comprises by many absorbed layers, optimum selecting three-layer, every layer of density gradient that has different density to produce.When the density of absorbed layer when lower absorbed layer increases to higher absorbed layer, density gradient typically is " by force ".Preferably, cleaning pad of the present invention comprises the density gradient of " by force ", it has rapid absorption ability, can be on z direction and x-y direction liquid being drained effectively better is utilized bedding core, and can reduce the liquid that has absorbed into, particularly those comprise the tendency that the liquid of molten particle not is stressed away.Strong density gradient preferably includes at least two absorbed layers, and the density of first absorbed layer is about 0.01 gram/cubic centimetre to about 0.15 gram/cubic centimetre, preferred extremely about 0.1 gram/cubic centimetre, 0.04 gram per centimeter about 0.06 gram/cubic centimetre extremely more preferably from about of about 0.03 gram/cubic centimetre; The density of second absorbed layer is about 0.04 gram/cubic centimetre to about 0.2 gram/cubic centimetre, preferred about 0.1 gram/cubic centimetre extremely about 0.2 gram/cubic centimetre, 0.12 gram/cubic centimetre about 0.17 gram/cubic centimetre extremely more preferably from about; The density of first absorbed layer is about 0.04 gram/cubic centimetre, preferred about 0.07 gram/cubic centimetre, 0.1 gram/cubic centimetre more preferably from about among the present invention, less than the density of second absorbed layer.

In another embodiment, the density gradient of cleaning pad derives from three absorbed layers, and wherein the density of first absorbed layer is about 0.01 gram/cubic centimetre to about 0.08 gram/cubic centimetre, preferred about 0.03 gram/cubic centimetre about 0.06 gram/cubic centimetre extremely; The density of second absorbed layer is about 0.03 gram/cubic centimetre to about 0.12 gram/cubic centimetre, preferred about 0.07 gram/cubic centimetre about 0.1 gram/cubic centimetre extremely; The density of the 3rd absorbed layer is about 0.05 gram/cubic centimetre to about 0.2 gram/cubic centimetre, preferred about 0.08 gram/cubic centimetre about 0.15 gram/cubic centimetre extremely; Wherein the difference of the difference of first absorbed layer and the second absorbed layer density and second absorbed layer and the 3rd absorbed layer density should be at least 0.02 gram/cubic centimetre, preferred at least 0.04 gram/cubic centimetre.

In another embodiment, cleaning pad comprises that density is the 3rd absorbed layer that first absorbed layer of about 0.05 gram/cubic centimetre, second absorbed layer that density is about 0.1 gram/cubic centimetre and density are about 0.15 gram/cubic centimetre.Have realized that such density gradient can cleaning pad have or do not have on the z direction, have a plurality of width the layer condition under be present in the cleaning pad.

Because density gradient, the porosity of absorbed layer, i.e. the ratio of the pore volume of material and the volume of material reduces the increase with density typically.Porosity is very important, and especially for the cleaning pad that is used for cleaning hard surfaces herein, this is because the liquid typical case that cleaning pad absorbed is contained the larger particles material of appropriate amount.When dirty liquid entered cleaning pad by scrubbing layer, the larger particles material was hunted down in the hole of low absorbed layer.Along with the reduction of absorbed layer porosity and the rising of density, the larger particles material is caught by the more macrovoid of low absorbed layer, and remaining liquid is transferred in the higher absorbed layer.So just make the easier high-density layer of transferring to of liquid, and particulate matter is stayed in the hole of low absorbed layer.Therefore, it is more more effective than the cleaning pad that does not have strong density gradient to absorb the cleaning pad of liquid and particulate matter simultaneously.

When absorbed layer density during less than 0.1 gram/cubic centimetre, the elasticity of described layer trend reduces, and another key property of the cleaning pad of the present invention that this discusses just below.In order to improve the elasticity of a low-density relatively absorbed layer, thermoplastic, preferred bicomponent fibre material can be used for combining with the fiber of absorbed layer.In molten state, the thermoplastic of at least a portion typical case is moved to the crosspoint of fiber because of the gradient of capillary force between fiber.These crosspoints become the binding site of thermoplastic.When cooling, the thermoplastic in these crosspoints solidifies the formation binding site, and fibre substrate or anastomose in each layer are incorporated into together.This is of value to makes cleaning pad have extra overall integrity.Though by known to the people, their typical amounts are less than about 15% in the art for bicomponent fibers.The applicant has been found to be and has obtained desirable elasticity, density less than the absorbed layer of 0.05 gram/cubic centimetre preferably include thermoplastic such as bicomponent fibers at least about 20%, preferably at least about 30%, more preferably at least about 40%.A kind of preferred bicomponent fibers comprises the copolymerization of ethylene bicomponent fibers, and it comprises and be less than about 81% polyethylene three titanates nuclear and be less than 51% copolymerization of ethylene shell that material is available from HoechstCelanese company, trade name CELBOND ^T-255.

After this will discuss more fully, the present invention is directed to the mop that is used in combination with detachable cleaning foil or cleaning pad on the one hand, cleaning pad or cleaning foil link to each other with the mop head of flexible bottom surface, and a part wherein preferably has the basic stepped profile that is, itself and the interlock of disposable cleaning pad.For simple and clear purpose, the present invention is a floor mop this discussion, but is appreciated that the present invention also is applicable to the mop of other type and has the cleaning foil releasably fixed thereon and the cleaning appliance of cleaning pad.

148 and 248 illustrates with illustration.Among Fig. 5, a pad that comprises the stepped design of three front parts 148,248 and 348 illustrates with illustration.Certainly, the pad of stepped design of the present invention is not limited to contain two or three front parts.Those skilled in the art know that other staged cleaning pad also is applicable to the present invention, for example have only front parts stepped design pad or contain pad more than the stepped design of three front parts.Preferred most the bottom surface of pad 48 and at least a portion of cleaning foil 44 engages in the use, as shown in Figure 5.

As described in Fig. 4 and Fig. 5, the bottom surface of pad 48 has contour shape, profile size and gap, makes mop head repeat to do oscillating motion in use.Be not subjected to any theory constraint, it is believed that mop 20 is when motion is cleaned in simple lasting doing forward and/or backward, the width 153 of contact-making surface 152 can repeat mop around contact-making surface 152 " waving " or " pivoting " or " rotation ", increase cleaning foil or the cleaning pad 44 direct surfaces that contact with dirt on the ground with this, or under the situation of " washing ", increase the area that contacts with the liquid that sprays on the ground.Therefore, this oscillating motion makes collection repeat contact along with the lower surface of thin slice and hard surface to be cleaned and separates, and can carry out on the surface area of the more vast scale of cleaning foil 44.The bottom surface cross-sectional profiles that phrase used herein " contact surface " is meant mop head 22 or cleaning foil 44 was cut the part of summit, bottom surface contact by straight line 56, and its cathetus 56 is vertical substantially with the lateral shaft 58 of mop head 22.

In one embodiment, the pad of stepped design obtains by adding front parts 148 with fixative on pad 48, and fixative can be adhesive, double-faced adhesive tape, Velcro ^Or other fixative as known in the art.Stepped design also can obtain by directly cast the front parts in the casting process of pad 48 and mop head 22, so it is permanent built-in.Preferably, the width of front parts is less than the width of mop head.In another embodiment of the invention, the front parts occupy the center of mop head, so mop head can axially move forwards or backwards equally.In another embodiment of the invention, stepped shape obtains by connecting in mop head or casting a plurality of fronts parts.The edge that is appreciated that these facade elements can be foursquare, circular, horn shape, structure or its any combination.The surface 152,252,352 towards being cleaned the floor of these front parts generally is flat, but noncontinuous surface can be employed and have same effect too.For example, these discontinuous shapes may exist with forms such as grid, projection, holes, and same effect can be used and have to the discontinuous shape of all the other kinds also.The front parts can be made with the material of different attribute.For example, these front parts can be made by general non deformable material.In another embodiment, all front parts can be made by general deformable material, and those materials comprise as filling body of foam, sponge, polyester filler, gel or liquid etc.Deformable material can be defined as anyly washes that (about 0.1 to 0.2 pound/square inch) loses its shape temporarily under the pressure normally dragging, and at the material that when pressure discharges, recovers their original-shape.Use the stronger material of morphotropism to form the front parts to when absorption pad is cleaned on the surface; the soakage that causes pump-absorb action to increase liquid by improved rocking action is very useful; because these materials easy deformation more when back and forth scouring of cleaning equipment; can also provide damping to protect ground to avoid possible damage; and cleaning is more prone to; particularly when use be thin pad or cleaning pad the time, thin pad or the absorption of cleaning pad nuclear core are narrower than the width of mop head or dedusting sheet.In another embodiment, general non deformable material is used in combination to make different front parts with deformable material.The combination front parts of being made by the material of different attribute can improve or improve the ability of mop head with respect to surperficial axially-movable to be cleaned.Mop head 22 and universal joint 26 preferred with ABS type polymer (as, come from terpolymer of acrylonitrile), polypropylene or other plastic material etc. prepare with injection moulding.Pad 48 and each independent front parts of stepped design can prepare with method of molding with polyurethane, perhaps use ABS type polymer (as, come from terpolymer of acrylonitrile), polypropylene or other plastic material etc. prepare with injection moulding.Mop handle 32 can use aluminium, plastics or other structural material to make.

The content of authorizing people's such as Policicchio United States Patent (USP) 6,101,661 is incorporated herein by reference, this patent disclosure a kind of cleaning pad that comprises the surface on a plurality of planes that contact with surface to be cleaned.In such cleaning pad, the thickness that forms all layers that absorb bottom enough produces desirable oscillating motion.Yet it is believed that this cleaning pad and improved cleaning appliance are used in combination to produce further improves and/or obtains optimized cleaning pad, it is thinner and/or make the pad optimization that optimized cleaning pad can be manufactured, and wherein thinner the and/or absorbability that can make of cleaning pad is lower.Make the thinner and absorbability of cleaning pad lower particularly useful when making those so-called " light-duty " pad.Less thereby need the less client of the area of cleaning concerning those houses, light-duty spacer has certain benefit.For these clients, the standard clean pad with several layers of absorbent material has too much " absorbability ", absorbability be defined as filling up before saturated the solution of absorbent maximum.Though it is useful making " light-duty pad ", reduces the absorbability of pad and make it attenuation and may produce greatly influence the cleaning function and the performance of cleaning pad.For example reduce absorbability and can cause lower " absorption efficiency ", absorption efficiency be defined as filling up the solution of specified rate and given time of contact a following absorbent solution amount.In addition, because fill up do very thin, " oscillating motion " during scouring obtained reduction.This is because reduction of " axle point " height causes, and " axle point " is defined as the core and clearance distance away from the marginal portion of the pad on ground of the pad of kiss the earth.Stepped design in the bottom surface of mop head, it is believed that the axle point highly results from mop head rather than the pad, the axle point height that the stepped design of mop head combines with the stepped design of pad and produces is than United States Patent (USP) 6,101,661 disclosed cleaning pads have more superiority.

It also is very favourable that the improved cleaning appliance that mop head has a pad of stepped design is used in combination with the cleaning pad that comprises functional cuffs.It is believed that more effective oscillating motion makes functional cuffs roll more freely or move forward and backward when cleaning.This is the result who oneself rolls because functional cuffs has obtained more space.

As mentioned above, a target of the present invention is to improve the cleaning efficiency of cleaning pad, and cleaning efficiency can interrelate with the absorption efficiency of cleaning pad.The absorption efficiency that improves in order to measure has been carried out following test.

Be used to measure the method for the absorption efficiency of the cleaning pad that is used in combination with improved cleaning appliance:

Surface test

Porcelain floor and finished in advance floorboards of wood are tested, be determined at the situation under the quality requirements of different floors.Resulting Different Results can partly be interpreted as because different " wettabilities " in surface, and such fact, the ceramic tile that promptly is used for this test has grouting line (6 mm wides * 3 millimeters deep), wherein solution can be resident, thereby owing to the reduction that contacts on cleaning pad and surface makes the absorption of cleaning pad difficult more.Test area is 5 * 1 square metres ceramic tile surface and 5 * 1 square metres finished timber.

Test plan

In this test, have the mop head and mop head of plain cushion with stepped design, measure in conjunction with two kinds of different " standard clean pads " with different characteristic and a kind of " light-duty cleaning pad " respectively.The pad of stepped design comprise one with the mop head bottom centre front parts of bonding connection substantially.The actual size of front parts is that 25 mm wides * 265 millimeters long * 1 is millimeter high.These front parts are connected the bottom of the mop head of 114 mm wides * 265 millimeters long.The mop head of flat mop head and stepped design measure-alike, different is that it does not comprise the front parts.

Test employed standard clean pad comprise have different in width, three absorbed layers of length and thickness.First and second standard pad also comprise the functional cuffs of different pairs " ring-type "." light-duty " cleaning pad comprises the functional cuffs of two absorbed layers and a pair of ring-type, to be used for those of second " standard clean pad " similar.The logarithm that is used for the functional cuffs of second standard pad and light-duty pad will be done detailed description in the back.

(the propoxyl group propyl alcohol solvent by 2%, 0.01% non-ionic surface active agent and 0.005 NaOH are formed to use 10 milliliters cleaning solution on first test zone of 1 square metre, the pH value is 10.5), cleaning solution is evenly distributed on the whole 1 square metre zone.The pad Velcro of the drying of weighing in advance ^Be connected the bottom of mop head utensil.From the left side of test zone, cleaning apparatus to and fro wiping 14 times up to the end that reaches the right.Next the right from test zone begins to the left side, with cleaning appliance back and forth wiping 14 times once more.Then, the personnel that test move on on another test zone of 1 square metre and repeat identical program.Be used altogether when 50 milliliters of liquid altogether dry on 5 square metres the ground and with cleaning pad after, test is finished, and cleaning pad is weighed once more.Being calculated as follows of absorption efficiency: the quantity of determining to be cleaned solution pad absorbing multiply by 100 then and is converted into percentage with respect to using ground 50 milliliters ratio.

The result

We find that with respect to flat standard mop head, when using the mop head wiping of stepped design, the absorption efficiency of two " standard " cleaning pads and " light-duty " cleaning pad has all improved.The pad of using by observation post after the test of every kind of mop head, stepped design has not only produced more significant axial height and better cuff motion as mentioned above obviously, and stepped design also produced the pressure span at the core of cleaning pad, and this can make cleaning solution be absorbed from the center rather than the leading edge of pad.Therefore, each tested cleaning pad can both absorb the liquid of bigger amount, so the cleaning efficiency of these cleaning pads has improved.Observed result illustrates with schematic diagram in Fig. 6 and Fig. 7.The cleaning pad that is to use flat mop head test that Fig. 6 represents is to the absorption of dirty solution, and the cleaning pad of the mop head test that is to use stepped design that Fig. 7 represents is to the absorption of dirty solution.The different layers that forms the absorbing material of cleaning pad can produce density gradient in the central area of pad.Therefore, these cleaning pads absorb manyly to the central area.The mop head of stepped design has been optimized and has been passed through the absorption of the central area of pad to liquid, this is because the solution that sprays on the ground is forced through the absorption of cleaning pad core and uses density gradient towards z direction and the diffusion of x-y direction to optimize, as Fig. 8 and shown in Figure 9.Fig. 8 represents is solution motion (Sm) to the cleaning pad that comprises three absorbed layers (higher layer density higher (Hd), lower layer density lower (Ld)) with flat mop head.What Fig. 9 represented is solution comprises motion from the cleaning pad of three absorbed layers (higher layer has higher density, and lower layer density is lower) to the mop head with stepped design.The flat design of mop head makes absorption point move to the leading edge of cleaning pad, and the advantage that cleaning is lined with density gradient has significantly been reduced.

A key character of preferred cleaning pad and/or cleaning foil is to comprise one or more improved functional cuffs among the present invention.The applicant finds that functional cuffs has been improved the clean-up performance of traditional cleaning pad and cleaning foil and cleaning pad of the present invention and cleaning foil.Functional cuffs has improved the particle capacity gauge of traditional cleaning pad and cleaning foil and cleaning pad of the present invention and cleaning foil.

The cleaning pad that comprises functional cuffs has been done illustration in Figure 10, Figure 11 and Figure 12.Figure 10 is the perspective view of cleaning pad 200 that comprises the functional cuffs 207 of free-swimming, ring-type.The functional cuffs 207 of ring-type has two surfaces 209 and 211.In typical cleaning method, such as dragging and wiping, cleaning pad 200 is at surperficial upper edge Y to be cleaned _fDirection moves ahead, then along Y _bDirection retreats.Along with cleaning pad 200 at Y _fMove on the direction, functional cuffs 207 upsets make its 211 to contact with surface to be cleaned.Particulate matter on the surface to be cleaned is adsorbed on 211 of functional cuffs 207.When cleaning pad 200 at Y _bWhen mobile, functional cuffs 207 upsets make its another face 209 contact with surface to be cleaned on the direction.Originally by the particulate matter of 211 absorption, will between the layer 201 of the surface 211 of functional cuffs 207 and cleaning pad 200, be hunted down.Other particulate matter also can be adsorbed in the surface 209 of functional cuffs 207.

Figure 11 and Figure 12 with graphic formal specification comprise the cleaning pad 400 of two free-swimming, closed functional cuffs 411 and 413, similar to functional cuffs among Figure 10 207.In typical cleaning method, cleaning pad 400 is along Y _fDirection is crossed hard surface and is moved, thus functional cuffs 411 and 413 the upset face 417 and 425 is contacted with surface to be cleaned can the adsorption particle material.Cleaning pad 400 is along Y then _bDirection is crossed hard surface and is moved, and causes that functional cuffs 411 makes face 419 contact with surface to be cleaned with 423 with 413 upsets.Be hunted down between face 425 and scrubbing layer 401 by the particulate matter of 425 absorption.Face 419 and 423 can adsorb the more particles material from surface to be cleaned then.When cleaning pad 400 along Y _fDirection is crossed hard surface when mobile backward, and adsorbed extra particulate matter is hunted down between face 423 and scrubbing layer 401.Functional cuffs is connected as a single entity with the cleaning pad of the layer that contains a plurality of width on the z direction, as shown in figure 12, the height of functional cuffs (being the functional cuffs of full extension on the z direction) thus enough make greatly when functional cuffs during the ply that it can be the narrowest with width to the center line upset of cleaning pad.What Figure 11 represented is the cleaning pad 400 that comprises two functional cuffs 411 and 413, and wherein functional cuffs 411 and 413 can both be to the center line upset of cleaning pad, and this is preferred to cleaning pad 400 packings are used for selling again.The action of cuff is shown in Figure 13 and 14, and it has shown that mop is along Y _fDirection is forward with along Y _bWhen direction was mobile backward, the cuff 207 how big particle is connected on cleaning pad or the cleaning foil 44 was caught.

When the cleaning pad that comprises functional cuffs and/or cleaning foil on hard surface back and forth during wiping, functional cuffs from one side to another side " upset " or " rolling ", thereby adsorb and catch particulate matter.Cleaning pad and cleaning foil with functional cuffs demonstrate the ability that can better adsorb and catch the larger particles material, this typical case occurs on the hard surface, and have reduced drop once more tendency on surface to be cleaned of these particulate matters.Except collecting the bigger particle, cuff is also helping the solution diffusion and is eliminating the line that forms owing to the texture structure on the floor, thereby is playing an important role aspect the formation that reduces striped between dry period to greatest extent.The characteristic of this help solution diffusion is even more important for the cleaning appliance of " wet ", because spray solution is in concentrated especially zone in this case, has lower dosage or surface humidity more usually with the system of routine, uses the absorption pad wiping then.Because dosage is lower and concentrate on the zone that the sprinkler width covers, pad need make dirt loose, and absorbs with controllable speed.If pad absorbs too soon, will form dried stain when mopping floor, this produces striped in the time of will causing doing pad wiping dirt face.When the outer side of cuff was made of non-woven material, the cuff typical case can absorb some liquid between the fiber slit of forming non-woven material.The liquid that is absorbed by cuff is released in the motion that mops floor subsequently, thereby helps liquid to distribute more equably, and the striped of generation reduces to minimum will mop floor with dried cleaning pad the time.As noted earlier, with the dried cleaning pad striped that produces that mops floor is because pad absorbs too fast, especially when the dosage of solution very low or solution be actually lower frequency interval spray (for example, 2 square metres of frequencies of spraying have at interval been adopted, and the frequency of the sprinkling of suggestion is 1/2 square metre of interval, because this is about width that the spray modes typical case covers).When the cuff of leading edge forward mop floor during motion towards the center or the cuff of trailing edge backward mop floor during motion towards the center time, the solution distribution character that cuff provided also is further enhanced.

When cuff was faced the center of pad, floor slice had been cut off with contacting of the floor that is covered by cuff.Pad has been reduced by the absorbability of the part that cuff covers, and this is because liquid before entering nuclear core absorbed layer, need pass a plurality of layers (liquid need penetrate the thin layer of poroid shaping potential in the layer that forms cuff and the cleaning pad).

As previously described, cuff is at " catching " bulky grain, hair and Soft flocks and sprawl aspects such as solution and play an important role.These characteristics are very crucial to the overall performance of cleaning pad.Equally as previously described, do up and down mop floor that cuff seesaws during motion the time cuff function be optimized.In order to optimize this ability that moves forward and backward of cuff, found that the characteristics (outside is meant the part on cuff actual contact ground when mopping floor) of outside cuff should be different with the characteristics (part of cuff and self friction when inside is meant and mops floor) of inner cuff.Found design, when the inside of cuff and self friction, lower frictional force or " sliding force " have been arranged, higher friction power or " sliding force " have been arranged when the outside of cuff and ground friction for the cuff of an optimization.The difference of frictional force has caused causing that material slides or the mobile strength that needs varying level.Cuff preferably can move around freely, is easy to greater than disconnecting cuff inside and self the instantaneous strength that is connected because disconnect the strength of the instantaneous connection between cuff outside and the ground.

Functional cuffs can comprise different materials, those materials surround polyester, the polypropylene of spunbond, polyethylene, cotton, the polypropylene of formula including, but not limited to the film of poroid shaping, polypropylene, artificial silk or polyester, the water of combing through combing machine for fur, and blend.In the place of using free-swimming cuff, the material of functional cuffs should have enough rigidity, so that cuff can be from one side to another side " upset ", rather than rotates own flattening or around oneself.Material that can be by using high basic weight (as, basic weight be higher than about 30 grams/square metre) increase the rigidity of functional cuffs, perhaps add other material such as plain weave cotton, adhesive, artificial rubber, rubber belt, foam, sponge, scrubbing layer waits and improves rigidity, perhaps material is pressed onto together.Preferably, functional cuffs comprises that water surrounds the formula bottom, and it includes but not limited to polyester, cotton, polypropylene, and composition thereof, its basic weight be at least 20 grams/square metre and have the plain weave cotton material to make it hardening.

In order to determine which type of material is suitable for obtaining the cuff with desired characteristic described above most, we have carried out following test.

Find that the material that shows among the embodiment 1,3,5,6 and 8 has good properties as the internal sleeve hoop material, because during test, as shown in table 1, material and storeroom demonstrate lower sliding force value, thereby frictional force is lower.The back is at interior exemplary aperture film (as embodiment 1,3, shown in 6) to form inner cuff, and perhaps nonporous film (as shown in Example 8) is preferred internal sleeve hoop material.Alternative in addition material can be a non-woven material, and wherein fiber is coated by the chemicals of height or adhesive coating or adhesive and makes structure level and smooth, shown in embodiment 5.

In double-deck ferrule designs, the material shown in embodiment 10,11,12 and 13 has good properties as the outer cover hoop material, because when test, as shown in table 2, outside cuff demonstrates higher sliding force value, thereby frictional force is higher.These materials typical case is a non-woven material, and they have left over many free fibers in forming process.In addition, fibre substrate have to a certain degree integrality and the space of capillary, this be (rotate bonding, melt-blown or combing) because heat bonding, the combination of different melting points fiber (bicomponent fibers of inserting by air dryer) or twine formation such as (waterpower embossing).The free fiber and the space structure of capillary can absorb liquid, and it is one of higher reason of frictional force when contacting the wetland face.The non-woven material of thermal makes too much fiber be fixed by embossing style closely among the embodiment 9.This has just stayed wandering fibre and capillary space seldom, thereby shows relatively poor sliding force when causing the test of outside cuff.The characteristics of the wandering fibre in these materials also help providing the hook that adheres to for bigger dirt such as velveteen, hair and dust (catching the key function that these dirts are cuffs) etc.

Though cuff can be made by two kinds of different material laminations, also be possible by selecting a kind of material that superperformance arranged to use the plain weave cotton to form an effective cuff in internal edges as outside cuff.Such material is shown in embodiment 12, wherein one side of plain weave cotton is tested as inner cuff, the wet and slippery power of material and storeroom is 0.55 pound of (0.2495 kilogram) power, and when reverse side was tested as outside cuff, the wet and slippery power between material and surface was 0.65 pound (0.2948 kilogram).Also can form a kind of cuff of unitary construction, its FS fiber is capped, handle the material of back gained and the wet and slippery power of storeroom like this and reduced one side method is carry out chemical treatment, bonding, polymerization or its combination at cuff.In addition, also find also can be used to form the individual layer cuff as embodiment 1-2, embodiment 3-4, the described special poroid film of embodiment 6-7 in table 1 and the table 2.In double-deck ferrule designs, typically, the shiny surface of aperture film (being often referred to the back) is inwardly placed, because the frictional force (wet and slippery power) of such material and storeroom is minimum.Reverse side (referring to that sunny side on one side) typical case has form outstanding in processing or perforation procedure, this makes its quality more coarse, thereby causes the frictional force (wet and slippery power) of higher material and storeroom.In fact, the material of the part that the quality of described poroid film is coarse and the sliding force between the surface are higher than the frictional force (wet and slippery power) of the back part material and the storeroom of this film.Embodiment 1 in comparison sheet 1 and the table 2 and embodiment 2, embodiment 3 and embodiment 4, embodiment 6 and embodiment 7 as can be seen each relatively in the back have the lower frictional force (wet and slippery power) in uniformity ground with respect to sunny side.This makes these materials be suitable for the ferrule designs of single entry.Especially, we find that this material is very favourable to the application on the surface to be cleaned that needs cleaning.The coarse structure of sunny side also helps catching velveteen, hair and dirt, also find its part or all of outer surface spraying, coating, screen printing etc. and adhesive phase, chemical treatment etc. have also been improved these performances and/or improved frictional force (wet and slippery power) between material and surface, if necessary.Alternatively, other the good material that can be used as outside cuff comprises following material: it has the character as (embodiment 10,11, the 12 and 13) fiber described in table 1 and the table 2, can be connected into band shape, square, circle, rhombus or the like by adhesive connection, thermally coupled, mechanical connection, ultrasonic bond, thereby, the prominent zone of some sun is arranged on scouring face by the outside cuff that the aperture film forms.Optionally be, do not use non-woven material completely, the actual fibers and/or the natural fibers such as cellulose, fiber crops that are made of non-woven materials such as polypropylene, polyester, polyethylene, nylon can be used for completely or partially covering the exterior portion of aperture film to form the cuff of single entry layer.

Above most discussion concentrate on design be used for as the wet cuff that function the best in the wet environment such as drags.Yet, have the performance that functional cuffs also helps improving dry dedusting sheet.But, the frictional force (dried sliding force) the when characteristics of inner cuff and outside cuff need not exist based on liquid.With the wet applications similar that drags, require the frictional force (dried sliding force) of inner cuff material on one side and storeroom less than the frictional force (dried sliding force) between outside cuff one side material and surface to be cleaned for the preferred characteristics of dry dedusting.

When considering the characteristics of inner cuff, the frictional force of material and storeroom or sliding force value should less than 0.6 pound (0.2722 kilogram), preferably less than 0.5 pound (0.2268 kilogram), be more preferably less than 0.4 pound (0.1814 kilogram).For outside cuff, the frictional force on its material and surface to be cleaned should be greater than 0.4 pound (0.1814 kilogram), be preferably greater than 0.5 pound (0.2268 kilogram), more preferably greater than 0.6 pound (0.2722 kilogram).In addition, the ratio of frictional force between the frictional force of internal sleeve hoop material and storeroom or wet and slippery power and outer cover hoop material and surface to be cleaned or wet and slippery power should less than about 1, preferably less than 0.9, be more preferably less than 0.75.

In another embodiment of the invention, two layers of material is used to form functional cuffs at least.These the layer by between inner cuff and outer cover hoop material optionally fixing point be connected to each other.These optionally fixing point allow interlayer to have open space and passage.This can not only provide the space for passing outer captive dirt, can also provide the loop for more volume, makes cuff make and flatten under pressure when mopping floor then and the tendency of crumple reduces to minimum initial.
