MULTILAYER SUBSTRATES COMPRISING INTERCALATED LAYERS AND POLYETHYLENE.

Abstract

Multilayer substrates comprising upper and lower surface layers comprising nonwoven synthetic fibers and a layer of molten thermoplastic material between the upper and lower layers, wherein the thermoplastic material comprises polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100°F to 350°F. The multilayer substrate may include a cleaning composition loaded onto the multilayer substrate, wherein a fluid path through the molten thermoplastic material allows the cleaning composition to migrate from the upper surface layer to the lower surface layer.The multilayer substrate can be devoid of chemical adhesives, where the adhesion between the upper surface layer and the thermoplastic layer and between the lower surface layer and the thermoplastic layer is instead provided by the thermoplastic material itself, which bonds to bundles of fibers in the upper and lower surface layers that are in contact with the thermoplastic material as it melts.

In addition to these 3 layers, a cleaning composition is provided, loaded onto the multi-layer substrate. Because there is a top plastic film layer inside the texture of the substrate, there is a melting point, which allows the cleaning agent to move from the upper surface layer to the lower surface layer, provided that the fluid path of the layer of plastic material is maintained. by bear..

An inner layer is provided that adheres the entire multi-layer substrate (for example, different from the caps between the upper and lower outer layers), which adheres the entire multi-layer substrate into a single mass, with low risk of delamination, providing the necessary textures in relation to the surface, the sensation of the fibers, and absorbing the capacity to load the substrate.<W .lit|> :íaHo:r®l,.providing trina at the same time ar-s via ds fluid through the thermopile layer! read through the: that the cleaning compound can migrate from the outer surface layer to the outer surface layer, and particularly given the characteristics of the thermoplastic material, the softened thermoplastic material. 1§ by fasíen encapenla, surrounds, wraps c covers Pe erro modo the adjacent individual fibers^ of the tissue layer.,: providing: sea arais strong between the two adjacent layers, so that delamination is not produced. The fibers of the previous surface layers can provide different characteristics, so that they do not soften by melting.

Thus, the intercalated layer of thermoplastic cheese does not typically penetrate through the previous surface layers, so that none of the thermoplastic materials softened by melting with specific characteristics of this type are found on the exposed outer faces of the layer. This results in the advantage that relatively softer fibers can be used for rubbing and cleaning in contact with: fiber®: ata anda da®: by fusion Some pulp loading (e.g., a mixture of synthetic and pulp fibers) The fibers of the outer surface layers are advantageously held firmly to the melt-softened thermoplastic quasso layer. This gives the material a stable surface instead of wearing away slowly. Regardless of the paper and the layers, this configuration allows the 3 layers to be joined into an integral substrate structure without the need for adhesives. 1S qúdsrLopa..

Thermoplastic layer, which envelops or otherwise covers the adjacent fibers of the upper and lower layers, effectively bonding the adjacent layers together without any chemical adhesive to prevent the layers from delamining or separating. At the time that the dry layer layer is produced, any existing bond characteristics with the inner thermoplastic layer are broken, so that a fluid pathway is created through the thermoplastic layer, through which a cleaning composition or other liquids applied to the upper or lower layer can penetrate from one upper layer to the other, through the thermoplastic film layer. Once the dry substrate has formed, a desired cleaning composition can be loaded onto the multi-layer substrate. Due to the viscosity of the fluid path, even if the cleaning composition is loaded with a liquid into one of the upper or lower layers, it will pass through the substrate to the other outer layer through the thermal film layer. 2D XII.

' 7,696,109, already incorporated by reference. Any non-woven cape can be separated from a single fold, or each fold can be separated. When multiple folds are programmed, they can be adhered to each other to ensure adequate adhesion, using any suitable technique, including the use of adhesive tape. When a single fold is present in one of the upper and lower surface layers, there can be no chemical adhesive anywhere in the substrates of the single layer. When two folds are used in one or more outer surface layers, there may be a chemical adhesive present in the surface layers, i.e., between the folds, but it may not be present between the thermoplastic layer and the adjacent upper and lower surface layers. b. Intercalated layer in which a thermoplastic napa is provided, inside the wipe, intercalated between the upper and lower surface layers. Although the surface layers can also be thermoplastic, these outer layers may include: different types of tan delta than those of the intercalated thermoplastic layer. When no chemical adhesive is used to bond the 3 layers into a single integral structure that does not easily delaminate between layers, but in which the intercalated thermoplastic "cheese" layer is used for this purpose, the Applicant has found that any thermoplastic polymer will be suitable for such a purpose. For example, when testing various thermoplastic polymers, the Applicant found that various materials, even after the application, will readily bond to the adjacent upper and lower woven surface layers, but will form a weak bond if any exists.Of course, such a weak bond is unacceptable in a multilayer substrate that will be used as a cleaning wipe, as delamination must be avoided. According to the present invention, the multilayer substrates have sufficient adhesion between the layers so that they do not detach even when exposed to moisture (for example, when left to soak for weeks, in humid storage) or when used on hard surfaces. The inner thermolactic layer not only adheres to the multilayer substrate when it melts, but can also impart additional resistance to the outer layers.

The Applicant found a characteristic or key element of a thermoplastic material, such as a lower layer, which is of the value of the difference. The value of tan delta is an engineering characteristic that can be evaluated for polymeric and plastic materials and provides information regarding the amount of characteristics of the liquid viscous phase (3:Q) versus the characteristics of the solid electrical phase (T) in a given material at a given temperature.Tan delta is calculated simply as the ratio of the viscous modulus divided by the elastic modulus for a given material, at a determined temperature. Figure 4 shows the values ​​of 2% and 2% elastic iodine for three tested thermoplastic materials: polyethylene, polypropylene, and a bisque material comprising polyethylene.

After reaching a maximum around this temperature, the value of tan delta begins to decrease, to approximately 2.5, and falls somewhat below 0.2 (for example, approximately 0.18) at approximately 000 *5270SF. Tan delta for the material is between that of polypropylene and polyethylene for a large part of the temperature range, up to approximately t < 250 'F where it is higher than that of the polyethylene. Both polyethylene and polyethylene include points along the temperature range from 100°F to 150 'F where tan delta is at least 0.1 (for example, greater than 0.1 to 0.4, or greater than 0.2 to 0.3).

Therefore, in ana· area 11 sao i in ®i thermoplastic material selected for the inner interlayer has a tan delta value that is at least 0.2 (e.g., from 0.2 to 0.4, or from 0.2 to 0.3) at some point within the temperature interval of 100 °F to 150 °F. In: one embodiment, the selected thermoplastic material may: have: such a tan delta value at the particular temperature at which the thermal calendering stage is carried out (e.g., 150 °F, 175 °F, 200 °F, 225 °F, 250 °F, 75 °F, 300 °F, 325 'F, etc-.,) o ·' u ..

When including any pulp fiber in the outer surface layers, it may be important to ensure that the temperature is low enough so that these pulp fibers do not: ignite, become brittle, or break down due to combustion, even below the paper's firing temperature of 451. As such, the selection of lower-firing-temperature thermoplastic materials may be preferred, provided they can provide good bonding to the outer synthetic surface layers. Figures 51-55 show that the wipes present in the multilayer packs can be packaged within any of several example flexible packs (Figure 5a), cylinders (Figure 5b), or other containers for storage and dispensing. The wipes can be pulled through the opening provided with these containers without fear of tearing or separating the various layers. The intermediate neoplastic intercalated layer can be quite thick. For example, it can have a thickness that varies depending on the structural characteristics of said layer (for example, if loose fibers are deposited, for example, loose Pico fibers or loose fibers comprising otherwise a material that has a characteristic of such desired thickness), or an intact film, such as yarn (for example, yarn), an intact non-woven layer, a woven layer, or the like). It will be evident that the intermediate neoplastic intercalated layer can therefore have a thickness that varies from 1.1 mm to 5 mm, from 0.91 M to 3 M, from 1.01 mm to 1 mm, from 0.11 mm to 0.1 mm, from 1 mm to 1 mm, and the like. The strength and / or stiffness characteristics of the towel may be at least partly due to the characteristics of the intermediate thermoplastic layer. For example, the strength and stiffness of the substrate as a whole may progressively increase as fibers, a film, a yarn, or a non-woven material (e.g., a non-woven material) are used respectively for the intermediate interlayer. Such materials are generally listed in order of increasing strength, where the strength and / or stiffness of the overall substrate increases with increasing thickness of the intermediate layer. Therefore, the thickness of the intermediate layer also contributes to the strength. 1>. dtepnte: of 1© ©cal the structure of 1 ©apar: is subjected to heat and / or pressure, to adhere the layers to each other and cause the formation of cracks, figures and the like through the intermediate thermoplastic intercalated layer, through which © one cleaning lotion: which: avettualmette te .load on :tl substrate can pass from a surface layer or, ,, - - ,o, ,,? te Layer O tewteda intermediate thermoplastic, to the other layer Súpteficial éytericr 1 ter: tete-pite ©o podria proprocioste dá:a· nonwoven outer surface layer of ©any suitable material 1Θ: (for example, tEte, which serves as a support for. deposit loose fibers (or fibers: forteóte te .hilqf site© the bóte or other support layer ótete 1 suitable exterior Fite-tete 1 to cover tepes ti cite te titeo© ©pateta· (by te; ótente another ©apa o© woven tete can yosieionarte .©©bre· the© or teste teeltas o 15 the loose yarn, and the 3-layer structure can be processed with heat and / or pressure suitable for melt-softening the intercalated thermoplastic layer, as described in the present dteutteteo of some embodiments, it may be desirable to provide the substrate with a bulging ether, to increase the volume and ' t - a , , . . where such character ci tx- । � KOO siv < n synthetic layers, With the synthetic substrate layers, such Bulging can be provided by ©any technique 25Λk , te ou ©t ' k* u ' u 1 i X _ xi . adding bulging material to it, which includes spacing, air pockets and fe ufe carao tfeifefea afemfefe eum-afeñada. As an example, one possible method for increasing the bulging of a synthetic composite substrate (for example, where each of the at least 3 layers described is a composite) can be achieved by heating one or both layers to the rollers that heat and press the refined substrate. For example, the feed rate of one or both layers may be greater than the cooling rate of the rollers, which causes the material of the heated layers to bunch up into folds as it enters the rollers. fenfe se pfefece el 1S ablandapien:tp por fesfen de la. caga ifeermedla, bufe baño que bafea bofe- igurafeón abril nada,, plisada· o abombada s.imi lar, including air spaces, se bloques when the intermediate layer softens by melting and joins the outer layer febreallmentadá, including di.nha eenf iguratfea pleasada,. 0 otherwise bulging or domed.

Optionally, other solvents, tonic agents and various other adjuvants may be present. They are often included in cleaning compositions, for example, some compositions may include lower alcohol solvents (e.g., C alcohols). The amount of such volatile solvents may be limited, for example, to less than 10%, less than 1%, less than 1% of 1%, less than 2% or less than 1 1 min weight. In some compositions, the cleaning product may be free, or substantially free, of such lower alcohol or other volatile solvents. tiles. Ammonium ammonium compounds have broad-spectrum antibacterial properties. A variety of different types of ammonium compounds can be used in the cleaning composition.Non-limiting examples of quaternary ammonium compounds are typically alkyl groups (e.g., a chloride) of alkyldimethylethyl or similar compounds. The alkyl groups of such quaternary ammonium compounds can typically range from Cu to Cv. Quaternary ammonium compounds are described in more detail in reference to this document, and will already be familiar to those skilled in the art. Organic acids can also be used to provide antimicrobial properties. For example, the organic acid can be included in a quantity given to: less than 1.1 to the hands of the other 1, up to 5, up to 4, up to 3, up to 2% or up to 1.51; in a cleaning solution.

With respect to the pre-wetting substrates, a quantity can be added only if the substrates retain the desired amount of liquid. The substrates are necessarily charged to their saturation point, but typically they are charged according to the standardization of the lamp in a quantity that reaches total saturation. For example, some substrates are capable of retaining up to 14 times their volume in the liquid. Due to various factors. Iris substrates can be charged with a charge ratio less than saturation, for example, from 1 to 4, from 2:1 to 3.5:1, from 2.5:1 to 3.5:1, or from 2.5:1 to 3.75:1. When the substrate can be configured to be completely synthetic, this can offer additional flexibility in the chemistry that can be dosed (e.g., 2I during manufacturing) on ​​a suitable substrate for its use, simultaneously eliminating the risk of unwanted incompatibility that may exist between components of said substrate and substrate, which may include pulp, other natural fibers, or other natural respects. For example, and without limitation, a wide variety of options can be used.

Wipes or other cleaning substrates can be provided pre-moistened with a cleaning composition. Moistened wipes can be kept for a long time in a sealable container such as, for example, inside a can or tub with a lid, fitting, or plastic container, or simply, jars, bottles, etc. Ideally, stacked, moistened cleaning substrates are kept moist. The resealable is particularly desirable when dealing with aqueous volatile liquid compositions, since quantities of liquid can be evaporated while the first few layers are being sealed, thus leaving the flakes with no liquid at all.

Typically, the cleaning substrates are separated and heated into the container and the liquid is added during the process. The layer, in bulk, is made impermeable to the liquids, to facilitate the loading of the wipes. As described herein, even if the thermoplastic film is provided before the thermal calendering process, cracks and other fluid pathways open up within the film during the thermal calendering, as contemplated herein. While this: may: not necessarily occur: with each and every one of the thermal calendering operations, it does occur as specified in the present document, The presence of these cracks to other fluid pathways that open during manufacturing of the multilayer substrate allows the liquid cleaning composition to pass from the wiper to the opposite surface through the thermoplastic film layer. Similarly, this allows the cleaning composition to migrate from one substrate to the next, for example, where the substrates are stacked in a stack, absorbing the liquid from one to the next. For example, the finished volume or weight of the cleaning composition can be easily dosed into the substrate, allowing it to be absorbed into the wiper stack.In the case of a donut configuration, when placing the 1:1 wiper at the bottom of the cylindrical container, a training of each wiper makes simultaneous contact with the cleaning composition on the inside of the container, where it can be observed at the height of each wiper (and the height of the donut). In reality, this can occur with a donut configuration, the thermoplastic film layer overlaps to include the fluid paths described, that is, it remains impermeable, since the upper and lower layers come into contact with the cleaning composition on the lower part of the container. Simultaneously, when any initially impermeable feature of the film is broken by the thermal calendering process, this can help, in addition to the fact that the liquid coating is exposed to the air above, throughout the entire surface.height of each towel and the donut in its. 1Θ eonjunW lí'tóepondí ente^ del. yruce.s:© de -envas-ado y dosflección, una vez manufactura y paquete, el substrate se puede: ufllliar po-sterícrmdnW^ para frotar una superficie:, fus sus-t-rares de limpieza ftutwd® cadas se puedas utd-liraf para 25 tratar varias superficies.

Antimicrobial efficacy and other characteristics The Multó lid substrates, for example, are tested to determine their ability to effectively deliver an anti-rubroblating quaternary ammonium compound to a surface during 1m cleaning. For example, the substrates of the present invention can be loaded into cleaning solutions that include from 0.1 to 3%, such as from 0.1 to 2% by weight of water.

These wipes may provide a greater absorption capacity than the wipes available on the market that do not include the same absorbent geometry described herein. This may be due to several factors, including the limited chemical adhesive content, if any, as well as the presence of absorbent pockets or spaces, such as those observed in the product.

The degree of lamination and the strength of the interlayers adjacent to the multilayer substrate typically depend on the temperature, pressure, or setting time and the pressure applied during the calendering operation. The temperature can be a factor responsible for the strength of the bond, while the pressure, time, and pressure can also have an effect and can also affect the resulting texture. The texture is the surface layer of the pulp fiber and the pattern of a layer, giving the layers a non-metallic appearance.
