Abstract

A basesheet for a wet wipe which includes multiple fibrous layers. At least one of the fibrous layers of the basesheet includes either (1) polyethylene fibers formed by a blend of polyethylene and an additive or (2) polypropylene fibers formed by a blend of polypropylene and an additive. For example, a fully hydrogenated hydrocarbon resin may be used as an additive with polyethylene to form polyethylene fibers which have a lower melting temperature of about 87 degrees Celsius. Polyethylene layers produced with such fibers may have an enhanced strength, produce less lint and be more securely attached to an adjacent fibrous layer. Polybutylene may be used as an additive with polypropylene to form polypropylene fibers to produce a more flexible layer with an increased attachment to an adjacent fibrous layer. The polyethylene and polypropylene layers may also include natural fibers such as cellulosic fibers. These polyethylene and polypropylene layers may both be present in a basesheet or may be combined with other fibrous layers. One or both of the major exterior surfaces of the generally planar basesheet may be formed by a polyethylene layer to provide the basesheet with a relatively soft exterior wiping surface. The polypropylene layer may be advantageously combined with a softer layer to provide strength and resiliency to the basesheet. A three ply basesheet may include an inner polypropylene layer and two outer polyethylene layers to thereby take advantage of the different properties of these layers. The use of an additive with either the polyethylene or polypropylene fibers allows the properties of the basesheet to be further controlled to suit the basesheet for its intended purpose.

Description of the Invention (1) Field of Invention The present invention relates to multilayer wipes. This invention relates to a wet wipe comprising a multilayer substrate. Xiang Nao Technology Green i wipes are well known and have been made in many forms. The most common form of wipes is a large number of wet sheets packed in plastic containers. Wet wipes have been manufactured from a variety of materials and have been wetted with various suitable wiping solutions. Wipes have been used for baby wipes, hand wipes, household cleaning wipes, industrial wipes and the like. Generally, conventional wipes include a substantially single layer of a homogeneous material. For example, conventional wet wipes have been formed from the same airlaid material fabric that is mixed or distributed throughout the fabric. Wipes have been formed from a variety of polymeric, synthetic, and natural fibers such as polyester, polyethylene, polypropylene, and cellulose fibers. Other conventional wipes include the co-formation of polypropylene and cellulose fibers, where these fibers are uniformly mixed throughout the fabric. When Tian uses only a single type of fiber that is mixed throughout the thickness of the substrate material, the balance of the physical properties of the wet fabric (such as softness, flexibility, strength, integrity, and elasticity) is difficult to fully utilize. This is especially true for users who want to improve flexibility. For example, the fixed fibers used in wet wipes are stiff and provide strength and elasticity, but are not as soft or flexible as other fibers. Since other fibers used in wet wipes can also be made softer, but do not have sufficient wet strength to resist the force exerted by the user, and can produce bilita, the present invention understands the differences of the prior art 'and responds to the development 1 there are improved substances Multi-layer wet wipe substrate with characteristics including use in forming wet

Extra fiber dust, not including polyethylene or polypropylene fibers, was used on the substrate. The substrate including the polypropylene and polyethylene layers can be derived from the advantages of the different characteristics of the two fibers. Polyethylene fibers are generally more pliable and therefore softer than polypropylene. This is due to the inherent differences between polyethylene and polypropylene in viscosity, chemical structure, and fiber coagulation. Thus, substrates made of polyethylene fibers will generally be softer than similar substrates made of polypropylene fibers. In any case, the same properties that increase softness can negate other substrate properties, such as tension, layer adhesion, elimination of fluff, and fiber fluff. Among recent features, substrates made of polypropylene will generally be superior 'to polyethylene substrates but will not have the softness provided by polyethylene substrates. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs These substrates generally have two oppositely disposed major outer surfaces. The side ends of the substrate have a limited surface area and are generally not used as a replacement or cleaning surface. Therefore, the polyethylene layer provides the softness advantage, which can be used to define one or two major outside surfaces of the substrate. For example, in a two-layer substrate, a polyethylene layer may be defined as a major outer surface of the substrate, whereas in a three-layer substrate, a polyethylene layer may be used to define the two major outer surfaces of the substrate. Similarly, a polypropylene layer may be combined with a layer having greater flexibility.

These additives can be mixed into polyethylene or polypropylene to use fiber-forming additives. The additives stored in lie ethylene or polypropylene fiber can affect the characteristics of polyethylene polypropylene, and by changing the characteristics of the substrate to Other methods are available for substrates suitable for special use. According to an embodiment of the present invention, polyethylene and polypropylene layers may be combined to form a two-layer substrate. In a substrate, where the first layer includes polypropylene fibers and the second layer includes polyethylene fibers, the first layer of polypropylene has first and second major surfaces disposed oppositely. Similarly, the second polyethylene layer has an inwardly facing major surface and an outwardly facing major surface. The inwardly facing major surface of this polyethylene layer contacts the first major surface of the polypropylene layer. The outwardly facing major surface of the polyethylene layer is defined as the outside surface of the substrate and provides a softer wiping surface, while the polypropylene layer increases the strength of the substrate.

Invention Description (7

The weight ratio printed by the Intellectual Property Office of the Ministry of Economic Affairs and Consumer Affairs Co. is about 25/75 ~ 75/25, and it is beneficial whether it is about 50/50 or 65/35. A suitable polyethylene is obtained from Dow Chemical Company under the trade name ASpUN 683 iA. An additional embodiment of the invention may include an additional fibrous layer. For example, a three-layer substrate can beneficially include an inner polypropylene layer and two outer polyethylene layers. In this way, the outward facing surface of the two polyethylene layers can be defined as the main outer side of the two-phase T configuration of the substrate. surface. The inwardly facing major surface of the polyethylene layer is located in contact with the two major surfaces of the polylayer, whereby the polylayer provides strength to the substrate that does not negatively affect the softness of the major surface of the substrate. Natural fibers can also be included in one or more substrate layers. Polyethylene and polypropylene fibers do not coexist under heat and generally do not adhere well to each other. In any case, polyethylene and polypropylene fibers can be trapped in each other appropriately between layers. For example, in a substrate layer containing a co-formed layer of polyethylene and cellulose fibers and a co-formed layer of polypropylene and cellulose fibers, polyethylene and polypropylene fibers can be entangled with each other and with the cellulose fibers As a result, the foot is fixed between the layers and can be bonded to the cellulose fibers at least. Interlayer adhesion and entanglement can be improved by thermo-mechanical effects, in which the substrate layer is heated by _ heating flat and heated between printing rollers. The combination of additives in polyethylene or polypropylene fibers can also improve the adhesion between adjacent polyethylene and polypropylene layers. The use of adhesives as additives can provide these results. A variety of different adhesives are known in the art and can be used to improve adhesion or cohesive properties in bonding. These adhesives are effective in adding materials to limit the consistency of the adhesive. These adhesives often have widely distributed molecules.

The softening point of these adhesives can range from 50 to 150. C changes. These adhesives can improve the adhesion of synthetic rubber materials by reducing the deformation resistance of the material at a low rate of deformation (to promote the formation of bonds on contact), while at the same time at a higher rate of deformation (to provide stronger separation resistance) Increase deformation resistance. By reducing elastic recovery and promoting plastic deformation, this adhesive can make the amount of adhesion more intimately contact the surface, thus improving the bonding strength. The purpose of adhesives is well known, and the amount of special synthetic rubber materials and adhesives can be measured or confirmed by comparing the shear storage modulus of synthetic rubber materials with and without adhesives. It has been found that when the polyethylene fibers of the wet substrate are made of polyethylene and a fully hydrogenated hydrocarbon resin additive, such as the adhesive REGALREZ 1126® manufactured by the company HerCules Inc. in Wilmington, Delaware, adjacent to the polymer The peeling strength of Otome and polypropylene layer can be significantly improved. The degree of layer adhesion or peeling of adjacent layers can be determined in the manner described in the example below. Furthermore, it has been found that a polyethylene blend containing 80% polyethylene and 20% regalrez 1126 (R) made fibers has about 87. The melting temperature of C is printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. This is about 130 with virgin polyethylene. C Melting temperature comparison is used to form a mixture. By reducing the melting temperature of polyethylene fibers, and in the absence of a corresponding decrease in the effect temperature ', it is believed that during the formation of polyethylene compared to the original polyethylene, these 4, QS $ maintained in a semi-melted state for a longer period. It is also believed that this allows more adhesions to be formed between individual polyethylenes and truncated dimensions. It is assumed that the existence of additional adhesion is to increase the tension of the layer, reduce the number of soft cloths and improve the polyethylene and adjacent fiber layers. 11 Mavis-D: \ Patenf \ Pk001.06 ~ \ 0628 \ PK-001-0628-1.DOC March 21 2001 529924 A7 ___B7 * V. Attachment between inventions (9). Therefore, despite REGELREZ⑧1126's "bonding," the trait was originally any reason to increase the number of fiber-to-fiber bonds. It is also believed that lowering the resulting melting temperature of polyethylene can potentially have a beneficial and increasing effect on the number of bonds. It can be easily understood that increasing fibers The number of fibers bonded to the fiber will increase the tension of the layer. It is believed that the number of fibers and fibers bonded in the polyethylene layer will reduce the two types of soft cloths. All polyethylene layers have the possibility of manufacturing polyethylene soft cloths, that is, separation from the base cloth Polyethylene fibers are produced. When the polyethylene layer further includes natural or other fibers, the other fibers that are lost will also make soft cloths. Then, when the fibers of the polyethylene fibers are increased to bond with the fibers, the less loose polyethylene fibers and Individual polyethylene fibers generally adhere to the layer. Therefore, less polyethylene fibers are suitable for becoming loose and making soft polyethylene cloth. As the fiber and fiber bonding of polyethylene fibers are also increased, it will provide more firmness. Fiber web, which will enhance the mechanical capture of any non-polyethylene fibers present in the layer, The second reason to reduce S cloth. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs also believes that increasing the fiber-to-fiber adhesion in polyethylene fibers to improve layer adhesion. When there are more fibers between polyethylene fibers When bonding with fibers, individual polyethylene fibers that are not bonded to fibers or fibers from adjacent layers are suitable for other fibers that are more firmly fixed to the polyethylene layer. In any case, increasing the number of fibers and fiber bonding can also reduce the number of fibers. The softness of the ethylene layer. The base layer containing 65 wt% cellulose pulp and 35 wt% polyethylene fibers formed from 80 wt% polyethylene and 20 wt% REGALREZ 1 126® can be borrowed by individual ratios to 65 wt% fibers The layer formed by plain pulp and 35 wt% original polyethylene is less soft and clear.

Description of the invention (10) This item can reduce the softness of polyethylene material and affect it—some fairly individual methods The fiber characteristics in the formula. It has also been found that the use of additives with polypropylene fibers can improve the adhesion between polypropylene and adjacent layers of polyethylene. For example, the use of polybutene as an additive can increase the viscosity of polypropylene fibers And it has been found that a clear effect of at least 20% and 50% on the layer adhesion. The use of polybutene as an additive can also be found to reduce the stiffness of the substrate. The reduction of the stiffness of the substrate (ie Increasing flexibility) generally has a clear effect on the touch of the substrate. In addition, an increase in flexibility can cause a hafnium layer, and the inner layer does not form the main outer surface of the substrate, and this clear effect is created on the touch of the substrate. Polyethylene acrylic is another additive that can be incorporated into polypropylene fibers by itself or in combination with polybutene to increase the viscosity of polypropylene fibers. Polypropylene and polypropylene blends are described in U.S. Patent No. No., which is incorporated herein by reference.

Description of the invention (1 1) Natural fibers (such as cellulose fibers) can be used to wet wipe substrates to provide improved adhesion and moisture. Natural fibers can also provide space in substrates, which can increase substrates. The moisture content of the sheet. Examples of natural fibers suitable for use in the present invention include not only cellulose fibers (such as wood pulp fibers), but also cotton fibers, flax fibers, jute fibers, silk fibers, and the like. Thermoplastics suitably used in the present invention Examples of polymeric fibers, in addition to polyhydrocarbons (such as polypropylene and polyethylene), also include polyamides and polyethylene (such as polyethylene terephthalate). Another suitable synthetic fiber includes mainly nylon and man-made fibers. If the multilayer substrate is a combination of synthetic and natural fibers, such as polypropylene and fiber-plastic fibers, the relative percentage of synthetic fibers and natural fibers in the layer can be adjusted according to the ideal characteristics of the wipes. Variations in a wide range. For example, 'this layer may contain about 20 wt% to 95 wt%, ideally about 20 wt% to 60 wt%' and more desirably about 30 wt% to 40 wt% synthesis Fibers are based on the dry weight of the layer. Synthetic and natural fiber layers can be made by known methods that are good at technology. In general, it is desirable that layers containing synthetic and natural fibers can be formed by co-formation to provide Generally the same distribution of natural and natural fibers is found in individual layers. The manufacture of co-formed layers is described by Anderson et al. In U.S. Patent No. 4,10,324, issued on July 11, 1978 ; MaFarland et al., U.S. Patent No. 4,604,13, issued on August 5, I986; and U.S. Patent No. 5,3,50,624, issued on September 27, 1994; their merger This is for reference. Generally, this co-formed layer contains thermoplastic polymer melt-blown microfibers (such as polypropylene microfibers) and cellulose fibers (such as wood pulp fibers).

Description of the invention (1 2) At least one main airflow is formed to form' This airflow contains synthetic fibers and fuses the main bundle with at least one natural fiber bundle. In a violent state, the primary and secondary beams are fused to form a composite beam containing homogeneous fiber distribution. This integrated airflow walks directly towards the forming surface until the air forms a layer of material. A plurality of co-formed layers may be formed continuously to provide a majority of the co-formed fabric. As mentioned before, the adhesion of the polyethylene and polypropylene co-formed layers can be enhanced by thermomechanical action, where the substrate layer is occupied by a heated flat stone and a heated printing roller. The printing rollers can be gathered together with any raised pattern which provides ideal entanglement and interlayer adhesion. Ideally, the printing roller is defined as a protruding pattern at most bonding positions, and this bonding position is defined as about 4 to 30% of the bonding area of the total area of the roller. The pressure between the roll and roll temperature must be balanced to produce a substrate with sufficient strength and integrity while maintaining the softness of the outer layer. The temperature and pressure can be changed according to the type of fiber to provide the ideal wipes. In a particular embodiment, these layers include at least one layer of polyethylene fibers and other layers of polypropylene fibers, and the pressure between the rollers may be about 50-900 Newtons / cm, and at least one roller temperature Can be about 40 ~ 150. c to improve entanglement and adhesion. Under temperature and pressure conditions, polyethylene fibers deform to provide mechanical entanglement with polypropylene fibers and the possibility of sticking to polyethylene fibers. As a result, these layers are entangled and are stuck in individual areas in a pattern arrangement consistent with the embossed pattern on the printing roll. The multilayer substrate may have a total basis weight of about 25 to 120 grams / square meter, and desirably is about 40 to 90 grams / square meter. The basis weight of the substrate can also vary depending on the use of an ideal wipe. For example, a suitable substrate for wiping the skin can be this paper size (please read the precautions on the back before buying this) ^ eWOOi ^ fl-lDocMa ^ 21, 2001 529924 A7 B7 V. Description of the invention (1 3) The basis weight is 60 to 80 g / m², and ideally is about 75 g / m². In its If embodiment, the 'substrate layer may include a co-formed layer of polypropylene and cellulose fibers and polyethylene and cellulose fibers, and has a basis weight of about 60 to 90 g / m², ideally about 80 G / m². Depending on the desired characteristics of the wipes, each substrate may or may not have the same basis weight. For example, in a three-layer co-formed substrate, the substrate includes an inner layer of polypropylene and wood pulp fibers, and two outer layers of polyethylene and wood pulp fibers. The basis weight of these layers can be defined as about 10%. The weight ratio of the outer layer / inner layer / outer layer of / 8〇 / 1〇 ~ 4〇 / 2〇 / 4〇 'is preferably about 25 / 5〇 / 25 ~, and more preferably about 30/40/30. The total weight of the substrate is the basis. When wetted with the solution, the substrate has sufficient strength to resist the force applied by the user. In substrates comprising polypropylene and polyethylene layers, a layer comprising polypropylene fibers will generally provide a soft outer surface of the wipes. Thus, this substrate layer has higher tension than a single layer containing polyethylene fibers, and provides a softer outer surface than a single layer containing polypropylene. The multi-layer substrate according to the present invention can be manufactured on a single manufacturing line including a plurality of rows to form a row. Each forming row is constructed to provide a separate layer. For example, the first and last formation rows can be formed to lift and supply the outer layer, while the middle and inner formation rows can be formed to provide one or more inner layers. During the formation action, the mechanical entanglement of the fibers in the adjacent layers adheres to the adjacent layers. Bonding can also be formed between adjacent layers of fibers to provide further attachment of adjacent layers of the substrate. Subsequent thermo-mechanical bonding can also be used to improve the adhesion between adjacent layers. Each forming row will include a suitable outfit to provide the desired fabric type.

The slender bundles are then narrowed with a high-speed gas flow to cut the polymer bundles into individual small diameter microfibers. This melt-blown mold is a well-known technique. Natural fiber bundles concentrated in melt-blown microfiber bundles can be provided by the action of a conventional pulp roll, which is a well-known technique. Alternatively, one or more wet wipe substrate layers may be made from different materials, such as meltblown sheets of polymeric microfibers. For example, an inner strong elastic layer can be formed from meltblown polypropylene fiber, while a soft outer layer can be formed from polyethylene and wood pulp fibers (as described above). The soft and fertile outer layer can also be provided by different types of materials, such as airlaid, carded web or meltblown materials, which are made by well-known techniques. The base cloth of the present invention is used to form a wet wipe by adding an appropriate solution to the base cloth. This solution can be any liquid that can be absorbed into a wet wipe substrate and can include a variety of different ingredients that provide the desired wiping characteristics.

This solution may also contain lotions and / or medicaments. The amount of solution contained in each wipe can vary depending on the type of substrate used for the material, the type of solution used, the type of container in which the wipes are stored, and the wipes to be used. Generally, each wipe will contain about 150 wt% to 450 wt% solution ' based on the dry weight of the substrate. It is generally desirable that the number of solutions contained in the wipes is about 300 wt% to 400 wt%, and beneficially about 330 wt%, based on the dry weight of the substrate. .......... .... — |. |, |--,,,-..........

The constant speed printed by I Co. (or tensile tester) is used to perform this peel strength test. Appropriate tensile testers and negative components are available from Instron Corporation of Canton, Mass. Or Sintech, Inc. of Research Triangle Park, North Carolina. The handles of the tensile tester are mounted parallel to each other. The tensile tester device is as follows: the speed of the coupling is set to 20 soil 0.04 inches / minute (5.08 soil 10 mm / minute); the specification length is set to 1.0 soil 0.04 inches (25 soil 1 mm); the initial measurement was set at 0.5 to 0.04 inches (13 to 1 mm); and the final measurement was set to 0.04 inches (152 to 1 mm). This test was performed by initially separating polyethylene and polypropylene layers at the end of the sample. These layers are divided into lengths of about 1 inch and no more than 2 inches. The two layers were then placed in the opposite handle of the test equipment, so the sample was straight and not slack. The test equipment is then used to pull the layers away at a specified rate (by which the layers are separated to form an angle of 180 °), while keeping in mind the force (Fg) required to separate the layers. Fluff Removal For the measurement of fuzz removal of flakes, a modified Gelbo device can be used. A suitable test facility is available from American Test Corporation, PO Box 3189, 1415 Park Avenue, Hoboken, NJ (0730). This test is used to determine the relative number of particles separated from a fabric when continuous bending and twisting actions are added. Any sample determination uses at least five substrates. Initially, at least two substrates were selected, and upper and lower substrates were left only for sample defense. The test samples are clean, dry, and environmentally friendly.

Into any other deformation. Testing on six to ten samples is generally sufficient to provide a moderate degree of confidence in obtaining an average sample. When the average sample 估计 is estimated, ′ can exclude the number of biases 値. To perform this test, a 9,9 ×, 9 (23 cm x 23 cm) dry substrate was placed in a modified Gelbo bending device, where it was tied to a support sheet between two tubular discs. Install this sheet carefully and handle it to a minimum while bending the tip to the maximum distance. The sample has a gap at the top end of the tube formed by the sheet, and the mechanical direction of the sheet is consistent with the long axis of the tube. The sheet was then turned and bent for 5 minutes to eliminate fluff. The two holders have a curved stroke of 4.7 inches (119.8mm), a handle twisted to 180 and a scrap rate of about 60 cycles per minute. After 5 minutes, the flakes were removed and the amount of radiation-removed fluff was measured. Due to the amount of fluff removed, it is better to measure the basis weight of the sheet before and after bending the sheet than to use a particle counter. Weighing these samples rather than using a particle counter also prevents the need to perform tests in a sheet-like flow hood 100 clean room, or wrap the device in a clean Plexiglas® room and remove with filtered air. The test equipment is located in the general test atmosphere, and the samples have the general test atmosphere conditions. The test atmosphere is either in accordance with the ASTM state (65 ± 2% RH and 72 ° 2 ° F) or in the ΤΑρρι state (50 ± 2% RH and 72 ± 18 F). Individual fluff removal results are quite uncertain.

Regardless, from a comparative order point of view, the reproducibility of these tests has been found to be very good, thereby providing a comparative measure of important fabrics and a tendency to eliminate fluff. Total Energy or "Cup Pressure" Based on the "Cup Pressure," the test determines the total energy of the nonwoven fabric. This cup pressure test is estimated to measure the highest load (also called "Cup Pressure,") which requires a 4.5 cm diameter lower end of a hemisphere The stiffness of the fabric is estimated to extrude a 23 cm x 23 cm piece of fabric into an approximately 6 · 5 cm diameter × 6 5 cm high cup. However, the cup fabric is surrounded by a cylinder of approximately 6.5 cm in diameter to maintain the cup pressure. The same deformation of the fabric. An average reading between 5 and 丨 〇 can be used to measure the final number of feet, when there is little or no variability in individual readings, it can serve as a few readings, and when there is more variability in the readings , Prefer the number of Xingyi majority. The lower end is aligned with the cup to avoid contact between the inside and the lower end of the cup, which will affect the reading. The lower end drops at a rate of about 25 inches / second (38 mm / minute). This cup pressure test causes the total energy required to squeeze the specimen ("cup pressure ,,"). This total energy is from the beginning of the test to the maximum load point. The total squeeze energy is calculated from the measured area under the curve formation. This curve is the load (g) on the shaft and the distance (mm) from the beginning of other tests to the upper and lower end of the maximum load. Therefore, the squeeze energy is recorded in grams-mm.

Description of the invention (24) Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5 as the peel strength, with a width of grams / 5_Q8 centimeters (g / 2 inch width) * The peeling strength was poor and insufficient. This is because the layers prior to separation, as demonstrated by the above test results, reduce the removal of fluff, and the era 3 proves to have a significantly higher peel strength than the control code. The peel strength of code 2 was not measured because the layer failed before peeling. This indicates a non-high peel strength indication. (First, if the peel strength exceeds the layer that cannot be attached, further increase in peel strength is limited.) These results are also shown in the sample additive combination in polyethylene fibers to provide a larger paper storage ' and increase layer adhesion. In any case, these results were produced simultaneously by adding cups 2 and 3. Increasing the cup pressure means increasing the stiffness of the substrate. This is generally interpreted as a decrease in softness. The main tactile comparison also indicates that the increased pulp preservation and peel strength 达成 is achieved by reducing the softness of code 2 and 3. Some test results also prove that the use of additives with polypropylene fiber to adjust the material parameters of the substrate is effective. When comparing cup presses, code 4, all have lower softness than PP control code (formed in the same way as code 4 to 6), and two of these samples are even lower than PE control code Softness. In any case, these results generally occur simultaneously by increasing tension. The above sample results provide proof that the combination of additives in the polyethylene or polypropylene fibers of a multilayer wet wipe substrate can provide the ability to improve the physical properties of the final multilayer substrate. These layers are then picked and combined to produce a substrate with the proper balance characteristics of the final wipes. The principle of pressure-retaining paper for 6 ene is always negative.
