Abstract

A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within its wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. The intake capability of the absorbent system is maintained or improved over current system by keeping a second layer of the absorbent system at allow saturation levels through as many insults of the product as possible, while providing optimum intake performance through appreciate control of the composite properties. The low saturation in this layer provides void volume for the incoming insult as well, as a high permeability, thus increasing the intake rate of the absorbent system as a whole, but the structure of the low saturation layer is also balanced to provide an appropriate high level of capillary tension to provide enough control of the liquid to stop leakage from occurring. This low saturation layer is used in addition to a surge material and provides intake functionality in addition to that provided by the surge material. In particular aspects of the invention, the body side layer of the absorbent core does not extend over the entire surface of the overall absorbent core, therefore is not used as the high saturation, wicking layer, but as the intake layer. This arrangement also allows the intake layer to be in direct contact with the incoming liquid, therefore allowing for more immediate access and improved intake function. In additional aspects, at least one primary layer region can have a non-uniform, selectively zoned basis weight distinction. Particular configurations of the at least one primary layer region can be constructed with a target area of the primary layer region having a basis weight which is less than a basis weight of another non-target portion of the primary layer region.

Description

4p727 Printed by the Consumers 'Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 Five' Invention Description (1) Distinguish the technology. The current invention is related to the layered absorptive structure. More specifically, the invention relates to layer-layer, synthetic absorbent structures in which each layer has a specific structure and arrangement to provide the desired number of functionalities of the synthetic layered structure. BACKGROUND OF THE INVENTION The goals of disposable absorbent articles such as baby diapers include that the product is not exposed, that the wearer has a dry feel, and that it has a comfortable fit when using the product. Therefore, absorbent articles generally include an absorption center that provides flow control and other absorption functions required to achieve product efficacy goals. The absorption center of the absorbent article is generally composed of wood pulp fibers, while the super-absorbent material is mostly distributed in the absorption center to improve the capillary effect of the fluid. The absorptive center Tongfeng is bell-shaped, T-shaped, or a similar shape to reduce the absorption width in the middle part and provide the wearer with fit and comfort. Absorbent articles often leak before fluid pores in the entire absorption center become full. One of the problems caused by leakage is that the suction and collection center will not be able to completely and quickly absorb mud after a large amount of fluid enters the absorption object. Another issue related to leakage is that the absorption center will not be able to move or distribute fluid, moving it from the target area area of the absorbent article to the more distal end area that the absorption center has not yet used. As a result, only the central target area of the absorption center is completely wet; this wet and heavy absorbent material is too thick and too large, resulting in poor efficacy and poor fit, and it cannot provide wearer comfort. The shortcomings of these absorption centers are particularly obvious in thin and narrow division and area absorption designs with bifurcation widths less than 4 inches. The absorption in the target area of this design is small, so there is a better fit. The paper size of the table applies the Chinese National Standard (CNS) A4 specification (210'〆297 mm)

The current absorption centers of absorbent articles have failed to meet current efficacy goals. The ability of the design can not provide the fluid absorption and distribution function of the absorption center fluid which is required for the design of subdivided and highly efficient absorbent articles countercurrent. Therefore, there is a need for a new absorbent structure that can provide better fluid absorption and analysis.

Matching force can move the fluid away from the target area, so that the product can maintain the expected fluid absorption during use. N Brief description of the invention Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economics The disclosed invention is an absorbent system that includes multiple layers of absorbent layers. Two or more regions of the absorbent layer can be staggered in a specific way, which allows the mud to fall into a specific layered area. Limiting the fluid to the stratified area increases the ability of the stratified area to move the fluid, because the wetting effect is increased and the role of capillaries is enhanced, which can increase fluid absorption. The capillary action of the absorption system can be improved or maintained through the eye system, because the second layer of this absorption system can maintain a low degree of wetting when the product absorbs a large amount of fluid, and at the same time through the appropriate control ability in the synthetic characteristics Provides maximum absorption. The low degree of wetting of this layer provides sufficient absorption space and higher throughput, thereby increasing the absorption rate of the entire absorption system. The properties of this layer can work simultaneously with high pore forces to provide sufficient fluid control to prevent leakage. The low wetting zone area can be used not only for the fluid control material layer, but also to provide another layer of absorption function in addition to the fluid control material. This invention is special in that the body-side layer of the absorbent structure does not stretch across the entire surface of the absorbent system, it provides an inhalation layer area outside the highly wetted, absorbent layer area. This security allows direct contact between the absorbent layer area and the fluid, so the fluid has a more convenient entrance, thereby improving fluid absorption.

However, the current invention can be used in other items such as children's training pants, feminine care products, incontinence items, protective outer pads, and similarly designed disposable items. Generally, the disposable items such as disposable clothes have limited uses, and do not need to be washed or reused after cleaning. For example, disposable diapers are contaminated by the wearer and discarded. In the present invention, the machine fixing system is a system 'which includes a common action component, which can provide a desired fixing effect through manual interleaving. The present invention provides: an absorption system including an absorption center, the absorption center including multiple layers, which can provide more space in a specific target area, better permeability, and better fluid absorption. Absorption systems, especially the system's central and central zones, can channel fluids from the target zone to produce the desired amount of space, such as by using absorption or other means. The fluid can also be concentrated in the layer area of the absorption center. This layer area can provide the expected relatively high fluid distribution force. At the same time, this layer area can provide space, absorb the fluid, and maintain low wetting. In the larger case, the relative basis weight or super-absorbent concentration of the layer area can be designed or arranged so that it is in the system with the proper characteristics of the material to provide better efficiency. However, it turned out that certain combinations were more effective at improving efficacy than others.

It t 482727 A7 B7 V. Description of the invention (7) The ability of this layer to move and distribute fluids using capillary pores can be increased because of the relatively high degree of wetting and the designated layer also has more water. Capillary action of the absorption system, especially the capillary action of the absorption center, can be maintained or improved through the traditional system. The way is to keep the absorption system's initial and absorption layer areas low in spite of the large amount of fluid absorbed by the product. Clarity while providing synthetic properties! Appropriate control to maintain optimal absorption. Maintaining a relatively low wettability of q in the region of the absorbent layer can provide more space for fluid and penetration, thus increasing the absorption rate of the overall absorption system. At the same time, the absorbent layer area can be designed to provide an appropriate degree of capillary pore tension to control the movement of the mud 'and avoid unnecessary leakage. In addition to the independent fluid control region, this low-wetness absorption layer region can be additionally provided, which can provide an absorption control function in addition to the fluid barrier material. In special designs, this area of the absorbent layer can be located on one side of the absorbent structure body, or it can be designed not to extend across the entire area of the absorbent structure. Therefore, the original body side layer region can be used as the absorbent layer region, rather than the high-wetness absorbent layer region. This arrangement can also make the absorbent layer area directly contact the fluid that is about to enter, so that the fluid that is about to enter has a quicker and more convenient entrance, and provide more efficient absorption functions. Layers can be designed individually or in combination to provide better absorption and distribution functions, especially the absorption and distribution of aqueous phase fluids. For example, improved efficacy can be achieved by improving the physical and / or chemical synthesis of synthetic materials, or by improving the design of ingredients.

Description of the invention (8) --- = AP) The composition can provide a combination of absorption, distribution and retention functions. There has been a need to improve materials, systems, and structures to enable Lico to produce improved absorption, distribution, and retention functions. To provide improved resistance to leakage, the invention contains improved materials that can exhibit at least one of the better qualities. Therefore, the overall efficiency of the system has also improved. For example, the absorption function can be improved by controlling the fiber and molecular size of the relevant layer material, the capillary effect of the layer, the basis weight of the layer, and the composition of the layer. For example, the distribution or distribution function can be improved by controlling the fiber, grate, and knife sizes of the constituent materials, the fluid contact angle of the materials, the surface tension of the fluid, and the basis weight of the materials. To further improve the expected absorption characteristics, several important factors have been identified to work together to provide better overall system efficacy. These factors include the expected fluid conduction in the absorption system and the fluid absorption. Another factor is the system's conduction absorption. The volume conduction is a number, which is based on the physical characteristics of the absorbent material, especially the absorbent material located in the target area of the absorption system, and it is related to the capillary action of the absorption center structure. It is expected that the minimum fluid conduction 値 is not less than 2.5 * 10-6 cm3. Alternatively, the fluid conductivity is not less than 3 * 10-6cm3 'or 3.5 * 10-6cm3 to provide improved efficacy. Furthermore, in this invention, the fluid conductivity can be as high as about 5 * 10-6cin3. Alternatively, the fluid conductivity may be about 7 * 10-6cm3, or 9 * 10-6cm3, or larger, to provide better efficacy.

It represents the amount of fluid removed from the target area of the absorbent structure described above during vertical absorption. This number represents the ability of the absorbent structure to remove fluid from the target area between each absorption, and at least one layer of the absorption system is designed to provide the expected Liu body capillary effects. Desirably, at least one layer region of the absorption system, especially the original layer region of at least one absorption center, is required to provide not less than about 10% of the fluid absorption plutonium. Alternatively, the fluid absorbent is not less than 5%, or not less than 20%. In addition, in this invention, the fluid absorption of the absorption system can be as high as about 60%. Alternatively, fluid absorption may be as high as about 65%, or 70% or more, to further improve its efficacy.

Or, combined with conductive absorption, at least about 15 * 10-6cm3, or 16 * ι0.6cm3 'to provide improved average efficacy. In other arrangements, combined conduction absorption is at least about 18 * 10-6 cm3 to provide the desired efficacy. In the absorption design with narrow and small areas, the target area of the product cannot provide enough space to effectively absorb fluids such as urine in a dry state. To compensate for the lack of space, a certain amount of SAp can be added, which is sufficient to absorb the fluid absorbed during this time. Adding fAP retains the fluid, and after the fluid is absorbed, it provides the desired leak resistance. Although some features have been discussed separately in the past, it is still difficult to effectively combine these advantages in a single synthetic structure while retaining the expected consumption attributes. Difficulties faced in the past are often related to maintaining relatively low SAP content throughout the structure or in a single layer, with the goal of improving capillary action. While maintaining a low SAp concentration in the product, the relatively large thickness of the product can provide the desired pore effect.

Invention Note (1C) The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed a moderate absorption layer to increase the absorption power, while maintaining another layer of high SAP concentration to achieve the desired pore effect of small and small products. Similar systems fail to provide the expected efficacy because fluid preferences flow to relatively high SAP-centric regions. In layers with a lower relative SAP concentration, the amount of residual fluid is not sufficient to provide the expected absorption. In order to overcome the above-mentioned shortcomings, the present invention specifically includes an SAP control rate (contrOiled_rate sap) in the absorption system. Through the {AP control rate, such as a SAP-specific low rate, the fiber structure in a specific distribution layer region can maintain a high concentration even if a specific amount of SAP is contained in the distribution layer region. In a particular arrangement, the controlled low rate SAP is initially located in a layer area other than a distribution layer. As a result, the thin SAP design can selectively wet the low SAP layer while maintaining the expected overall high pore effect. In addition to adding low-rate sap, alternative mechanisms have also been considered to provide different levels of absorption fluid concentration between specific layers. For example, layer-specific relative wettability and / or density are designed to produce the desired distribution effect. = Figure 1 and Figure 2. For example, the absorbent synthesis system (26) of the present invention includes a fluid control zone ~ (84), and an absorbent pad or central structure (30). The absorption center (30) is divided into multi-layer structured layer regions, and the characteristics of the independent layer regions are arranged in a specific manner to uniformly absorb the inhalation and absorption effects of the composition, and provide an improved leakage effect. Generally speaking, the currently described absorption center is the first layer, which contains a super absorbent body (moved from the surface of the innermost body side of the object to the outermost surface of the object), and other layers that can maintain this layer intact during functional tests Sexual composition. Such a first layer contains at least about 5 wt% superabsorbent molecules. (Absorption center knot Read the notes on the back before filling this page)

Description of the invention (11) (Please read the notes on the back before filling This page) is tied to the final absorbent layer, and its placement order takes precedence over the fluid-impermeable layer that prevents leakage of the diaper, so it moves from the innermost side of the object to the outermost surface of the object. Therefore, the absorption center (30) in the illustrated design includes the first initial absorption layer (48), the outermost layer (28 or 36) covering the thin layer, and the components located therebetween. The absorption center does not include the surface layer (2 4), the fluid control layer (84) containing no superabsorbent molecules, and the bottom layer (22). 1 The proper balance of the absorption and absorption characteristics can be achieved by several determinants, such as fluid conduction. Capillary action, basis weight, density, molecular size, relative amount of fiber, etc., and a combination of the above factors. The fluid conductivity of the absorber is related to the available space and structural permeability in various wetting degrees in general use. To provide improved effectiveness of the absorption system, the rate at which fluid enters the absorbent junction should be as close as possible to the rate at which the fluid is transferred to the absorbent composite structure. Fluid conduction can represent the inhalation capacity of the overall absorption system (26), and it can also represent the absorption center (30 ). In addition, the fluid must be moved from the entry area to a longer area of the absorption system for storage, so that the entry area can more efficiently receive the next fluid entry. Fluid absorption 値 represents the ability of the absorbent structure to transfer fluid from the target area during each absorption process.

Extend to the side that is approximately 8.5 inches (2 16 mm) away from the foremost edge of the absorption center. At the same time as increasing the fluid conductivity, it is desirable to increase the volume of the absorption center structure, because the product thickness of objects with narrow points and widths will become too large. Therefore, there is a need for a design that can provide the desired inhalation effect, such as using a fluid-conducting plutonium as a standard, while maintaining a thin absorption center (30) and an absorption system (26).

Desirably, the superabsorbent Tau is about 値 minutes, or at least about 2 minutes, to provide improved efficacy. On the other hand, Tau 値 can be up to 40 minutes or more. In addition, the absorption center, especially the different layer regions of the absorption center, may contain a combination of certain superabsorbent materials, wherein the Tau- 値-ratio of at least one specially paired superabsorbent material is approximately equal to or greater than 2: 1. The Tau- 値-ratio can also be as high as about 5: i or greater to provide better efficacy. Desirably, a superabsorbent material having a relatively large Tau 値 is placed relatively near the surface of the body side of the absorption center. Techniques suitable for measuring the T au-値 -ratio of each • two absorbers can be found in the procedure of the Flooded Absorptivity section under no load in the current description. Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The super-absorber with specific control ratio can be a super-absorber, in which individual super-absorbent molecules are treated with hydrophobic covering to delay the absorption of the solution into the molecules. For example, the superabsorbent may be a superabsorbent coated with particles. The absorption center of the molecule is composed of partially carbonated polyproponic acid (formed by the procedure disclosed in US Patent No. 5,629,377), and the molecular center is covered with a hydrophobic silicone elastomer. Such control ratio super absorbers can be purchased through DOW Chemical Company, B: \ 0476 \ pk-001〇476.connie, April 3, 1.

Invention Description (30) The company is located in Midland, Michigan, USA. Another type of controlled ratio superabsorbent may contain relatively large molecular specifications to provide a low surface area to volume ratio, thereby producing the expected absorption rate. Controlled rate superabsorbent molecules can also have a spherical or other three-dimensional form, which can form the expected low surface area to space ratio, thereby delaying the absorption rate. i In addition, the bulk properties of superabsorbent polymers can be modified to provide the expected delayed absorption. ; For example, controlled rate superabsorption can be added to an anionic high-molecular electrolyte that is interleaved with the polyvalent metal cation in the reverse direction. Water-soluble composites can be used to pour their staggered connections. Another control ratio superabsorbent can be incorporated by covering or other treatments, which can simply affect the rate at which the fluid disperses into the superabsorbent molecules, or limit the fluid to provide a slower absorption rate. The covering or other treatment may be elastic or non-elastic, while the covering or other treatment may be hydrophobic or hydrophilic. Covers can be eroded, dissolved, or peeled in specific ways to provide the desired absorption characteristics. Alternatively, the absorption rate can be limited and / or controlled by improving the neutralization ratio of a specific superabsorbent material, or by modifying or controlling the chemical mechanism used to generate neutralization of a specific superabsorbent. The technology for determining the absorption under load (AUL) of super absorbers can be found in US Patent No. 5,550,189, filed by J.

Each layer should be independent and tested independently. Record the target position with a permanent ink pen. The target position of the test layer is determined when the layer area is located at a predetermined position in the absorption center. The target area is located in the side center area, which is spaced inwardly by approximately 36% of the entire length of the absorption center from the terminal front edge of the absorption layer extending in front of the absorption center. Therefore, the extension of the absorption layer at the foremost end of the absorption center is not necessarily a test layer. Permanent ink ratio in the sample record target area. The target area of the test sample layer is determined when the layer area is located at a predetermined position in the absorption center. The target area of the test sample layer is the middle area of the two side extension lines of the sample layer. The first line extends from the center of the absorptive center to the inward end of the absorptive layer and extends inwardly about 24% of the length of the carcass. The second line extends from the center of the absorption center and the foremost terminal edge of the layer extends inwardly about 59% of the entire length of the absorption center. Both lines extend perpendicular to the long axis of the absorption center. If the two target area lines fall outside the center line of the test absorption sample, the fluid absorption of the test sample by definition is equal to zero.
