Description of the invention (1) General aspects of the invention _ The invention relates to exhibiting improved liquid handling properties that make it particularly useful for receiving liquid body exudates such as urine, menstrual 'sweat, or Hygienic absorbent articles of low viscosity excretory substances such as fluid handling elements for baby diapers, trousers, adult incontinence articles, feminine hygiene articles. Background / Previous Obstacles Materials that exhibit specific fluid distribution properties are well known in the general field of disposable absorbent articles and structures. These materials are increasingly associated with references to highly absorbent materials, also known as absorbent gelling materials or superabsorbent materials, or superabsorbents for short. This highly absorbent material does provide storage for aqueous fluids such as urine Fluid is a good component, but it cannot improve fluid transport, and even when using suboptimal designs and / or suboptimal materials, a decrease in fluid transport may occur and what is commonly referred to as "gel blocking ( gei_ blocking) "phenomenon. For example, in a structure in which a superabsorbent is uniformly mixed with cellulose fibers, '' should not exceed a certain critical concentration, which is strongly related to the choice of superabsorbent material so as not to deteriorate the effectiveness of the absorbent core material. As a result, there is a separation effect in the design of the absorbent core material with a large I, such as not only containing liquid storage areas or materials, but also areas having special properties to increase the uptake and / or distribution of fluids. Generally, one area can achieve the purpose of improving absorption and distribution at the same time. At first, the requirements for knife cloth materials were not very high, and standard tissue materials such as those used in core materials as a wrapper and, for example, described in M⑸⑴Teng⑻, were used to improve fluid distribution at the same time, as described in 4-fjing (Please read the notes on the back before filling this page) -----— II · II I--II 1 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, China ’s National Standard (cns) IF ^ T ^ T's 7 public meals) Printed by the Consumer Cooperatives of the Ministry of Intellectual Property Bureau 44946? 1 1 Λ: Β7 Γ-'Π- V. Description of the invention (2 EP-0 343 941 (Reising) or US-A-4.578 .068 (Kramer). Further developments can be exemplified as follows: EP-A-0.397.1 10 (Latimer) Reveals the inclusion of an overflow treatment section to improve fluid treatment, with specific basis weight, absorption time and residual moisture absorption Objects; US-A-4.898.642 (Moore et al.) Reveals specially reinforced, chemically hardened cellulose fibers and absorbent structures made from them; EP-A-0.640.330 (Bewick-Sonniag et al.) ) Reveals that these fibers are used in a specific configuration with a specific superabsorbent material. The goal of his method is to improve the wicking properties of cellulosic fiber-based materials, such as US_a-3.575.1 74 or US-A-4.781.710, in which a part of the structure is compressed to a higher density, resulting in smaller pores For example, to increase the wetting height along the "wetting line" or in a closed mesh pattern. Since some of these materials can show an unpleasant hard feeling, it is well known to form post-treatments to improve softness. "After formation `` Treatment '' refers to the process of making or forming a paper towel instead of increasing or in addition to increasing the softness. After forming and drying the paper towel, it is usually just further processing, such as combining paper towels with other materials to form Tissues are mechanically treated in individual method steps before absorbing the core material or article I. Examples of such treatments are US-A-5.1 1 7.540 (Walton) or US-A-4.440.597 (Wells).

Unless otherwise specified, all percentages, ratios, and proportions used herein are by weight. The requirements of the improved Fenyou Yuanlin for the distribution element can be determined by the observation element or the material contained in the element. Therefore, it is necessary to make the entire element or the individual materials therein meet the requirements proposed by the present invention. Therefore, the distribution element or the material that may be used for these elements according to the present invention can be explained by the following important parameters: First, the permeability sand at which the element or material is completely saturated. This permeability of conventional distribution materials is balanced to provide minimal resistance to fluid flow (i.e. high permeability) and sufficient capillary pressure to provide wetting properties, such as those produced by smaller pore sizes (i.e. Low reputation transparency). Permeability (k100) under full saturation should generally be more than i Darcy (1 Darcy is equivalent to 9.869.10 seven square meters), more than 2 Darcy is better 'or even 8 Darcy' or More than 100 Darcy is even better. Full saturation can be measured using a capillary adsorption test described later as the maximum absorption amount, which is equivalent to the capillary adsorption absorption capacity result at a height of 0 cm (CSAC (Capiuary

Relevance. This property has not been taken into account in previous material design considerations, and the known materials have a strong Sub-proportionai behavior, that is, actual penetration below 100% saturation It is significantly lower than what it should be when there is a linear correlation between actual permeability and saturation. "The second is capillary adsorption pressure, that is, capillary adsorption desorption pressure, such as in the capillary adsorption test described later. Measured. This parameter describes the ability of a material or element to release liquid to fulfill its role as a distribution element in an absorbent article. In addition, the distribution material can satisfy the high fluid flow in the vertical infiltration flux test described later. The rate of measurement is required, and this is usually better. The material provides a pass of at least 0,045 g / cm2 / s at a wetting height of 15 cm. Preferably, more than 0.06 grams per square centimeter per second is better, and more than o square centimeter per second is even better. By carefully selecting materials that meet these parameters correctly, the absorbent structure and / or each Important benefits are obtained from other objects. First, liquid distribution materials can be easily dehydrated after being loaded with urine such as gushing urine. This makes these materials ready for subsequent loading, as often occurs in actual use Secondly, these materials allow the liquid to have a more uniform liquid fraction, even under a load that is very small compared to the designed capacity. The goal is to avoid the accumulation of large amounts of liquid in certain areas of the object. In order to maintain the improved fit on the wearer, it is even more important in the design that the storage liquid is evenly distributed. -12- < Please close the precautions on the back before filling out this page) Pack --- -Order .-------- I < ^ ί -.1 i'b S 1- ίί — (C \ h ^ A4 V-1U ^ 'S-j7 ^ * 4) 449467 A: B7 five 3.

The material according to the present invention exhibits at least 丨 Darcy's materiality ... It is better to call V2 Darcy. Higher permeability 値 can provide less reduced resistance to fluid transport, and is Preferably, as long as this is achieved without reaching the other points mentioned in the essay. In particular, materials with permeability of more than 8 Darcy or even more than _ Darcy may be very suitable. As can be seen from the equation Therefore, the higher the SDP parameter is, the higher the ratio of the system to the subscale behavior. If the SDP is equal to i, there will be a linear relationship. The conventional split materials show a strong subscale. Behavior, such as can be illustrated by an SDP with a depletion of 3 or more. For this one, the permeability at 50% saturation is only 25% at 100% saturation. Therefore, other liquids are accepted and distributed The capacity of the load is also drastically reduced. Therefore, 'the material according to the present invention has an SDP of less than 3, preferably less than 2.75, more preferably less than 2.5, and even more preferably less than 2.

For example, the illustrated defoamable foam exhibits a thickness depending on the degree of fluid load or saturation, that is, it has a certain thickness at saturation τ, and due to the pore size of the foam, when the liquid is removed from it, Pain relief, so this thickness decreases when fluid is removed. Conversely, a certain thickness can be set to define a certain loading degree. Therefore, for this material, a simplified wheat permeability test can be easily applied to determine the correlation between permeability and saturation.

It is measured in units of water column height ("capillary height"). The Capillary Absorption Capacity Test (also referred to herein as the Capillary Absorption Test) measures the amount of test fluid absorbed or released per gram of absorbent element or material when the material or element is placed at different heights on a capillary adsorption device. The capillary adsorption and absorption capacity test is described in more detail in the following test method paragraph, which produces a capillary adsorption desorption height (CSDH 50) that releases 50% of the fluid volume at an adsorption height of 0 cm-which may be used in the case of the present invention The material should have a CSDH 50 of less than 50 cm, preferably less than 1000 cm, even more preferably less than 75 cm or even less than 50 cm. Particularly useful materials for the present invention are hydrophilic, flexible interconnected open-cell polymeric foam structures. With regard to this type of foam, the mechanical strength of the foam may be such that when the foam releases its liquid, it will dissipate under the associated capillary pressure. The elimination process reduces the effective foam capacity by a substantial factor related to the density of the foam, as explained later. This elimination can also reduce the amount of liquid that is fixed at the point of liquid intrusion if it is fairly uniform throughout the structure. ^ In this respect, the strength of foamed plastic is lower than that of the capillary tube produced by foamed plastic. When removed by the core and material storage components, foam plastic will disappear. Capillary pressure is mainly controlled here by adjusting the cell size of the foam (which is inversely related to the surface area per unit volume). Strength is controlled by a combination of crosslink density and foam density, which can be expressed as the crosslink density per unit volume as defined below.

The cells in the open-cell foamed plastic structure on this temple are large enough so that the liquid can be easily transferred from one cell to the other cell open or "window". Such substantially open-cell foamed plastic structures will generally have a reticulated nature, with individual cells being bounded by a plurality of interconnected three-dimensional branched networks. The tow of the polymeric material that makes up these branched networks can be referred to as a "pillar." For the present invention, as in a foam structure, the size is at least! At least one cell of the micron has fluid communication with at least one adjacent cell, and the foam material is "open cell". In addition to being open-celled, these polymeric foam plastics are sufficiently hydrophilic so that the foams can absorb aqueous liquids. The inner surface of the foam bed plastic structure is rendered hydrophilic by residual surfactants and / or polymer foam residues after polymerization, salts, or by a selected post-polymerization foaming plastic treatment procedure as described later. Sex. The degree of "hydrophilicity" of these polymeric foam materials can be quantified by the "adhesive tension" exhibited when they come into contact with the absorbable liquid.

About 20 to about 65 dyne / cm is better. One important aspect of these foams is their glass transition temperature (Tg). Tg represents the midpoint of the transition between the polymer's broken glass and the rubbery state. Foams with Tg at a higher temperature may be quite strong, but they may also be very hard and have the potential to crack. Such foams also tend to creep under stress and have poor resilience when used at temperatures colder than the polymer's Tg. Mechanical properties, specifically the desired combination of strength and resilience, typically require the proper selection of the range and amount of monomer types to achieve these desired properties. For distributed foam plastics useful in the present invention, the Tg should be as low as possible, so long as the foam has acceptable strength. Because of &, as far as possible, monomers are selected that provide a related homopolymer with a lower Tg. The shape of the glass transition region of the polymer may also be significant, i.e. it is narrow or wide as a function of temperature. The shape of this glass transition region is particularly relevant where the temperature of the polymer (usually room temperature or body temperature) is at or near Tg. For example, a wider transfer area may mean that the transfer is incomplete at the temperature in use. Typically, if the transfer is incomplete at the temperature in use, the polymer will exhibit greater rigidity and lower resilience. Conversely, 'if the transfer is complete at the temperature in use, the polymer can exhibit a faster self-compressed state recovery1' It is hoped that the τ g of the polymer and the width of the transfer region can be controlled to obtain the desired mechanical properties. In general, the Tg of the polymer is preferably at least about lor lower than the temperature during use. ❿ and transfer area (Please read the precautions on the back before filling out this page) -------- Order ---------

Description of the invention (16) The degree is derived from the loss tangent (i0ss tangent) vs. temperature curve in the dynamic mechanical analysis (DMA) measurement, as explained on October 8, 1996 US Patent No. 5,563,179 (Stone et al.). The polymer foams useful in the present invention can be described by a number of parameters. The foams useful in the present invention are resistant to gravity and wet the aqueous liquid to a significant height, for example, at least about 15 cm. The liquid column staying inside the foam creates a noticeable reduction in capillary pressure. The foam will disappear at a height determined by both the strength of the foam (in compression) and the surface area per unit volume of the foam. This height is the Capillary Collapse Pressure (CCP; Capillary Collapse pressure) expressed in centimeters. At this height, 50% of the volume of foam plastic at zero pressure drop will be lost. ≪ The preferred distribution foam useful in the present invention will have a CCp of at least about 15 cm, more preferably at least about 20 cm, and even more preferably at least about 25 cm. Typically, it is better: the distribution foam will have capillary pain pressure from about 15 cm to about 50 cm, more preferably from about 20 cm to about 45 cm, and even more preferably from about 25 cm.

Useful techniques include simple based on scanning electron micrographs of foamed plastic samples Measured. T The foam used in the absorbent for aqueous liquids according to the present invention has a number from about 20 microns to about 60 microns. The average cell size will be better, typically from about 30 microns to about 50 microns. , And the number of average pores / same size from about 5 microns to about 5 microns, typically from about 8 microns to about 2 microns ^ "Capillary suction specific surface area" is a measure of the polymeric network structure accessible by the test liquid Test liquid reachable surface area. Capillary suction ratio depends on both the size of the cell units and the density of the polymer in the soil foam, so it is a kind of quantification provided by the foam network structure to the extent that the surface can participate in absorption The total amount of this solid surface. For the present invention, the capillary specific surface area is determined by measuring the amount of capillary absorption of a low surface tension liquid (e.g., ethanol) that occurs in a foam sample of known mass and size. A detailed description of this procedure for measuring the specific surface area of foams using capillary suction is described in the previous U.S. Patent No. 5'387,207, Test Methods paragraph. Any reasonable alternative method for determining the specific surface area of capillary suction can also be used. The distribution foams useful in the present invention will preferably have a capillary suction specific surface area of at least about 0.01 m2 / ml, more preferably at least about 03 m2 / ml. Typically, the capillary suction specific surface area is from about 0.00 to about 0.2

Description of the invention (21) In terms of shear mixing amount, temperature, and Water to oil ratio (which can be converted to the final density of dry foam). Polymeric foams useful in the present invention can be prepared by polymerizing in the art-commonly known as "HIPE j, a certain water-in-oil emulsion with a very high water-to-oil ratio compared to" " The resulting polymeric foam is called "HIPE foam". A detailed description of the general preparation of such HIPE is listed in U.S. Patent No. 5,563,179 and U.S. Patent No. among many other parameters. The relative amounts of the water and oil phases used to form the HIPE are responsible for determining the The structural, mechanical and performance properties of polymeric foam are particularly important. In particular, the water-to-oil ratio ("W: 〇 ratio") in the emulsion changes inversely to the final foam density, and will affect the cell size and capillary suction specific surface area of the foam and the pillars of the foam. size. The emulsions used to prepare the HIPE foam used in the present invention generally have a volume to weight ratio of water to oil phase in the range from about 12: 1 to about 12 5: 1, and from about 15: 1 to about 90: 1 is more typical. Particularly preferred foams can be made from HIPE having a ratio from about 20: 1 to about 75: 1. The major part of the oil phase of HIPE will include monomers, co-monomers and cross-linking agents, such as those listed in U.S. Patent No. 5,387,207 below. Basically, these monomers, comonomers and cross-linking agents are substantially insoluble in water 'so that they are mainly dissolved in the oil phase rather than the water phase. The use of such a substantially water-insoluble monomer ensures that HIPE with appropriate characteristics and stability can be obtained. Of course, the types of monomers, comonomers, and cross-linking agents used here are such that the resulting polymeric foam-24- (CNS) Al UMu χ ------------- 装- ------- Order --------- Line- < Γ Qing first read on the back; i sound?

Description of the invention (22), material = local non-toxic and suitable chemical stability is very good . These single-agent monomers and cross-linking agents should preferably have little or no toxicity during the processing and / or use of the polymer foam after polymerization at a very low residual concentration. ’From the other-the basic ingredients are emulsifier ingredients that can form stable HIPE. This emulsifier component contains a primary emulsifier and optionally a secondary emulsifier, such as those listed in U.S. Patent No. 5,387,207 below. The oil phase used to form the HIPE comprises an early body component from about 85 to about 98 weight percent and an emulsifier component from about 2 to about 15 weight percent. The oil phase will preferably contain monomer components from about 90 to about 98 weight percent and emulsifier components from about 3 to about 10 weight percent. The oil phase may also contain other optional ingredients. One such non-essential ingredient is well known to those skilled in the art-a general type of oil-soluble polymerization initiator, such as described in U.S. Patent No. 5,29,82,0 issued on March 1, 1994 (Bass et al.

Another preferred non-essential ingredient is an antioxidant such as a hindered amine light stabilizer (HALS) and a hindered phenol stabilizer (HPS) or any other antioxidant that is compatible with the initiator system used. Other non-essential ingredients include plasticizers, additives, colorants, chain transfer agents, dissolving polymers, and the like. The discontinuous internal water phase of HIPE is generally an aqueous solution containing one or more dissolved ingredients such as listed in U.S. Patent No. 5,3,87,207 below. A basic dissolved component of the water phase is a water-soluble electrolyte. Dissolving the electrolyte minimizes the tendency of the mainly oil-soluble monomers, comonomers, and crosslinkers to dissolve in the water phase. _____ -25- .- · i (CN. ^ Ai ilfS) ---- ------------- Install -------- Order -------- -Line (please read the precautions on the back before filling this page) 449 46 Λ7 B7. &Amp; Underground 11.¾ Property Bureau 3 Labor consumption f:-.: 1 ^^. 5: ¾ V. Description of Invention (23 It is believed that this can minimize the degree to which the polymeric material fills the cell window formed at the oil / water interface by the aqueous phase droplets during the polymerization process. Therefore, according to the existence of the rhenium electrolyte and the ionic strength of the resulting aqueous phase, it can be determined whether the better polymer foam produced can be open-celled and the degree of open-celled. HIPE will typically also include a polymerization initiator. This initiator component is generally added to the aqueous phase of HIPE, and it can be any conventional water-soluble free radical initiator. It includes peroxy compounds such as sodium persulfate, potassium persulfate and ammonium persulfate, hydrogen peroxide, sodium peracetate, sodium percarbonate, and the like. Conventional redox initiator systems can also be used. Such a system is formed by combining the aforementioned peroxidation sigma species with a reducing agent such as sodium bisulfite, L-ascorbic acid or a ferrous salt. The initiator may be present up to about 20 mole percent based on the total moles of polymerizable monomers present in the oil phase. Based on the total moles of polymerizable monomers in the oil phase, the initiator is more preferably present in an amount ranging from about 0.0000% to about 10 mole%. It is preferred that the polymer forming the HIPE foam structure is substantially free of polar functional groups. This means that the properties of the polymeric foam will be quite hydrophobic. These hydrophobic foams can be used in situations where hydrophobic liquids need to be absorbed. Such uses include situations where oily ingredients are mixed with water and it is desired to separate and isolate the oily ingredients, such as in the case of oil spills at sea. When these foams are to be used as water-supplying liquids such as fruit juice splashes, milk, etc. for cleaning purposes and / or body fluids such as urine absorbents, they generally require further processing to make the foams very useful Hydrophilic. If necessary, the hydrophilicity of foam can generally be explained in the following U.S. patents (please read the precautions on the back before filling out this page) ---- Order --------- line 26-. ^ ' 2- ^ INTELLIGENT PROPERTY-; dimgongxiao #; '-]' '-Counseling ", " 44946?. Λ; ---- Β7 _____ V. Invention Description (24) No. 5,3 87,207 The way 'is done by treating ΙΙΕΕ foam with a hydrophilized surfactant. These hydrophilizing surfactants can be any material that enhances the water wettability of the surface of the polymeric foam. It is well known in the art and can include various surfactants, preferably non-ionic, such as those listed in U.S. Patent No. 5,387,207 below. Another material that is typically added to the HIPE foam structure is hydratable 'and water-soluble inorganic salts with better hygroscopicity or solubility. Such salts include ' e.g., Toxicologically acceptable alkaline earth metal salts. This type of salt and its use with oil-soluble surfactants as foamed hydrophilic surfactants are described in more detail in US Patent No. 5,3 5 2,711 (DesMarais) issued on October 4, 1994, Its disclosure is incorporated herein by reference. Preferred salts of this type include calcified calcium, such as calcium carbonate, which, as previously described, can also be used in HIPE as an aqueous phase electrolyte. Hydrated organic salt can be easily added by treating the foam with an aqueous solution of such salts. These salt solutions can generally be used to treat foam after the process of removing the residual aqueous phase from the polymerized foam is completed, or as part of it. The use of such a solution to treat foamed plastics allows better deposition of hydratable inorganic salts, such as calcium carbonate, with a residual amount of at least about weight percent of the foamed plastics, and typically ranges from about 0.01 to about 12%. Treatment of these fairly hydrophobic foams with hydrophilizing surfactants (with or without hydratable salts) will typically proceed to the extent necessary to impart proper hydrophilicity to the foam. However, some of the better HIpE type foams have proper hydrophilicity when they are prepared, and may have added i · -------- ^ --------- I ( Please read the urgent notes on the back before filling out this page) _______- 27- ^^^^ ftiTA ^ p- ^ f-/ ^ ik 4 9 46?

In particular, such preferred HIPE foams include the use of some of the previously described oil phase emulsifiers and chlorinated Xuan foams in HIPE. In those cases, the inner surface of the polymeric foam will be appropriately hydrophilic 'and even after the polymeric foam is dehydrated to a suitable level, it will still include a residual aqueous phase liquid containing or depositing a sufficient amount of calcium carbonate . The preparation of foam plastic typically includes the following steps: 1) forming a stable high internal phase emulsion (H1PE); 2) polymerizing / curing this stable emulsion under conditions suitable for forming a solid polymeric foam structure; 3) visualizing The solid polymeric foam structure needs to be washed to remove the original residual aqueous phase from the polymeric foam structure, and if necessary, the polymeric foam structure is treated with a hydrophilizing surfactant and / or a hydratable salt to make any desired hydrophilic Surfactant / hydratable salt deposition; and 4) then dewatering the polymeric foam structure. This procedure is described more completely in the previous U.S. Patent No. 5,387,207.

Therefore, in use, the object is generally placed on the wearer so that the area between the two legs extends upwards on the front and back of the wearer (for the wearer in the standing position) — Generally speaking, these objects have a length dimension exceeding their width dimension.

The legs of the absorbent core material in the description of the invention (31) are split Point 9 Although the bifurcation point of an object is usually at the center of the object (in the longitudinal direction), this is not necessarily the case. An object intended to be worn on the front can be smaller than the back (or rear) part. Its length dimension, or width, or both, or surface area-but also quite satisfactory. Moreover, the bifurcation point of the legs need not be located in the center of the absorbent core material, especially when the absorbent core material is not placed in the object in the longitudinal center. The bifurcation area is around the bifurcation point of the legs to cover the respective body openings, which are the areas of the drainage area. Unless otherwise specified, this area extends to 50% of the total core material length (which is defined as the distance between the front and back waist edges of the core material, which can be approximated by a straight line perpendicular to the longitudinal centerline). length. If the two-leg bifurcation point is located in the center of the object, the two-leg bifurcation area starts at 25/0 of the total length (when calculated from the positive core edge) and extends up to 75 of the total core length %. Alternatively, the front and rear quarters of the sucker core's length do not belong to the bifurcation area of the legs, while the rest belong. The length of the bifurcated area of the legs, which is 50% of the total absorbent core length, is the result of a baby diaper ', in which case it has proven to be a suitable way to describe the phenomenon of fluid treatment. If the present invention is applied to objects having extremely different sizes, it may be necessary to reduce these 50% (such as in the case of severe incontinence objects) or increase this ratio (such as in the case of extremely light or mild incontinence objects) . More generally, the bifurcation area of the article should not extend excessively beyond the discharge area of the wearer.

L fe cz B7 V. Description of the invention (32) The area still covers 50% of the total object length (longitudinal). However, it is unevenly distributed between the front and back, but it is proportionally adjusted to this deviation. For example, for an object with a total core length of 500 mm and the bifurcation points of the legs in the middle, the two-leg area will extend from 125 mm from the positive edge to 37.5 mm from the positive edge. Alternatively, if the bifurcation point of the legs is 50 mm away from the edge of the positive core material (ie, 200 mm from the edge of the positive core material), the bifurcation area of the legs will extend from 100 mm to 350 mm. In general, for an object with a total core length of Le, the two-leg bifurcation point is located at a distance Lcp from the edge of the positive core material, and the length of the two-leg bifurcation area is Lcz. The edges will be positioned at the following distance (1 -Lcz / Lc). For example, 'Absorbent articles may be baby diapers for toddlers (ie approximately 12 to 18 kg of infant weight). The size is generally called the MAXI size. The article must accept and retain both excretory material and urine, however, in the case of the present invention, the leg area must be primarily capable of receiving urine. The total area and size of the two-legged area will of course also depend on the respective width of the absorbent core material, that is, if the core material is narrower on the two-legged area than on the outside of the two-legged area, the two-legged area Has a smaller area (surface) than the rest of the absorbent core. Although 9F can consider the boundary between the two-legged area and the rest of the object as a curve ', it is outlined in this description as a straight line perpendicular to the longitudinal axis of the object.

Design capacity and final storage capacity In order to be able to compare different uses; brothers, or absorbent articles of different sizes, it has been found that "design capacity" is an appropriate measurement method. For example, infants represent a typical use group, but even within this group, urine load, frequency, and composition of urine can range from smaller infants (newborns) to toddlers. And there is a wide range of changes, and for example, there are changes among different babies. Another use group may be older children who still suffer from some forms of incontinence. And 'incontinent adults will also use this kind of object, which again has a wide range of loading conditions' is generally called mild incontinence to severe incontinence. As those skilled in the art can easily transfer this instruction to other sizes, for further discussion, the focus will be on toddler-sized babies. For this type of user, it was found that the urine load up to 75 ml was excreted each time, and the average volume of dysfunction was four times during the period of the female / human dental belt, resulting in a total load of 300 ml, and 15 ml / s The excretion rate is fully representative. Therefore, these items that can cope with this demand should have the ability to absorb this amount of urine. For further discussion, this is called the "designed capacity". This amount of fluid must be absorbed by the material that will eventually store the body fluid, or at least

Description of the invention (62) The report shall perform at least 2 measurements on each sample, and record various output parameters as a function of time. Of course, individual parameters may be related to each other and are mapped accordingly. To illustrate the materials applicable in this note, the accumulated flux at a height of 15 cm has been found to be particularly useful. Simplified Liquid Permeability Test This simplified permeability test provides a measure of permeability in two special states: it can measure 100% of a wide range of porous materials such as non-woven fabrics made of synthetic fibers or cellulose structures. Measure permeability under saturation; or for materials that reach a different saturation and have a proportional change in thickness but are not air-filled (respectively the external vapor phase), such as digestible polymeric foam Measure the permeability at different thicknesses at different thicknesses. 0 Especially for polymeric foam materials, it has been found that it can effectively operate the test at a high temperature of 31 ° C to better simulate the in-use state of the absorbent article. . In general, this test is based on Darcy's law, according to which the volumetric flow rate of a liquid passing through any porous medium is proportional to the pressure gradient, and the proportionality constant is related to the permeability.

Therefore, for a fixed or given sample cross-sectional area and test liquid viscosity, permeability can be calculated by measuring the pressure drop and volume flow rate through the sample. K = (Q / A) * (L / AP) \ The test can be performed in two variants. The first is called permeability through the plane (that is, the direction of flow is basically along the thickness of the material), and the second is in-plane permeability. (That is, the flow direction is in the Xy direction of the material). The test equipment used for the simplified and penetrating permeability test can be seen in Figure j, which is a schematic diagram of the overall equipment, and the illustration is a partially decomposed horizontal drawing of the sample dish. The test equipment includes a Approximately circular or cylindrical sample dish (120) with an upper part (121) and a lower part (122). Three calipers (145) and adjusting screws (140) arranged around each can be used to measure and adjust accordingly The distance between these parts.

A round sample (110) with a diameter of 1 inch (about 2.54 cm) was placed between two porous screens (13 5) inside the sample dish (120). The sample dish consisted of two 1 inch (2.54) Diameter) cylindrical object (121, 122), which is connected to the inlet storage tank (150) through the inlet joint (132) by the pipe fitting (180) and to the outlet tank (133) An outlet storage tank (154), such a soft pipe fitting such as a tygon pipe fitting. Closed-cell foam plastic cymbals (1 1 5) provide leakage protection around the sides of the sample. The test sample (110) was compressed to a thickness corresponding to the desired wet compression, and unless otherwise specified, it was set at 0.2 psi (about 1.4 kPa). The liquid was allowed to flow through the sample (1 1 0) to reach a steady state flow. Once the steady-state flow through the sample (110) is established, the volume flow rate and pressure drop are recorded as a function of time using a dynamometer (1 98) and a differential pressure signal electrical transducer (1 97). The experiment can be carried out at any pressure difference up to 80 cm permanent column (about 7.8 kPa). This pressure difference can be adjusted by the height adjustment device (1 70). From these measurements, the flow rate of the sample under different pressures and forces can be determined.

The following tests are outlined below. The number of layers' is then adjusted to maintain the material during the test at a minimum pressure drop between 05 mcm / s and 15 mcm / s at the maximum pressure drop. The flow rate of the sample should be lower than that of a blank sample at the same pressure drop. If the flow rate of the sample exceeds the flow rate of the blank sample for a certain pressure drop, more layers should be added to reduce the flow rate. Sample size: An arch punch, such as supplied by MCMaster Carr Supply Company, Cleveland, Ohio, was used to cut the sample to a diameter of [inch] (about 2 54 cm). If the sample has too little internal strength or integrity to maintain its structure during the required operation, a conventional low basis weight support member, such as a PET scrim nonwoven or mesh, can be added. Therefore, pre-cut at least two samples (if required, each made of the required number of layers).

Unless otherwise required, use a conventional caliper with a pressure foot diameter of 1 and 1/8 inches (about 2 86 cm) to produce a pressure of 0.2 psi (about 1.4 kPa) on the sample (110) ( Such as those supplied by AMES, Waltham, Mass., USA), measure the thickness of the wet sample at the desired compression pressure for the experiment (after a stabilization time of 30 seconds if necessary). Choose the proper combination of gasket materials so that the total thickness of the gasket foam (11 5) is the thickness of the wet sample! Between 50 and 200% (note that a combination of gasket materials of different thicknesses may be required to achieve the total desired thickness). Cut the gasket material (11 5) into a circular size with a diameter of 3 inches, and use an arch punch to cut a 1-inch (2.54 cm) hole in the center. In case the sample size changes during wetting, the sample should be cut to obtain the required diameter during the wet phase. This can also be evaluated in this preparation test by monitoring the individual dimensions. If these changes occur such that gaps are formed, or the sample is creped to prevent smooth contact with the porous screen or frit, the cutting diameter should be adjusted accordingly. Place the test sample (1 1 0) in the hole in the gasket foam (丨 1 5), and place the composite on the bottom half of the sample dish to ensure that the sample is flat with the screen (1 3 5) On the other hand, the contact was smooth, and no gap was formed on the sides.

Description of the invention (Qiu) When the experiment is started via the computerized unit (190), the liquid outlet flow automatically comes from the waste liquid storage tank (1 5 6) Turn to the outlet storage tank (1 5 4) and monitor the grace and temperature as a function of time for several minutes. Once the program is completed, the computerized unit will provide the recorded data (in digital and / or graphical form). If necessary, the same test sample can be used to measure the permeability at different pressure height differences, thus increasing the pressure between tests. The equipment should be cleaned every two weeks and calibrated at least once a week, especially for glass, dynamometer 'thermocouples, and pressure signal electrical transducers, which follow the instructions of the equipment supplier. The green differential pressure was recorded using a differential pressure signal electrical measurement converter connected to the pressure probe measurement point (丨 94 '196) at the top and bottom of sample m. Since there may be other flow resistances in the room that increase the recorded pressure, each experiment must be corrected by a blank test. The blank test should be performed daily under the required pressure of 10, 20, 30, 40, 50, 60, 70, 80 cm. The permeameter will output the average test pressure and average flow rate for each experiment. For each tested pressure of the sample, the computerized unit (丨 90) records the flow rate green as the blank-corrected pressure 'which further corrects the average test pressure (actual pressure) at each height of the recorded green differential pressure, This produces a corrected pressure. This positive pressure should be used in the DP of the permeability equation below. The permeability can then be calculated at each required pressure and all permeability should be averaged to determine the k of the material under test.

Description of the invention () The permeability is measured under the difference, and then a new sample should be used for the second and third repetitions. The measurement of the in-plane permeability under the same conditions as the aforementioned through-plane permeability can be achieved by modifying the above equipment, such as outlined in Figures 2A and 2B. These figures only show a partial exploded view of the sample dish, which Not in proportion. Equal elements are represented in an equal manner, such as representing the sample m of FIG. 2 as (21) with respect to the number (110) of FIG. 1 and so on. Therefore, the simplified sample vessel (120) passing through the plane in Figure 1 is replaced by the simplified sample vessel (220) in the plane, which is designed so that the liquid can only flow in one direction (depending on how the sample is placed in the vessel, it is longitudinal or transverse ) Β must be carefully minimized the channeling (wall effect) of the liquid along the wall, as it will falsely produce high permeability readings. The test procedure is then carried out in a manner very similar to the simplified test for crossing planes. The 4-water PP dish (220) is designed to be placed in the device basically as described for the sample dish (120) in the above-mentioned through-plane test, except that the pouring tube is guided to the bottom of the dish (220) Inlet connector (232). Figure 2Λ shows the exploded view of the sample, and Figure 2B shows a cross-sectional view through the height of the sample. The test vessel (220) is composed of two objects: a bottom object (2 2 5) similar to a rectangular box with a flange, and a top object (223) assembled in the bottom object (2 2 5) and also having a flange. ). The test sample was cut into a size of 2 inches x 2 inches (, ··· spoon 5.1 cm by 5.1 cm), and placed in the bottom object. Then place the top object (223) of sample 罜 1 in the bottom object (225) and place it on the test sample (2 10).

Description of the invention (70) flows through the Thai arch fitting and inlet joint (232) to the sample space, and then through the outlet joint (233) to the outlet storage tank. Since the temperature control of the fluid passing through the sample dish may not be sufficient due to the lower flow rate during this test, the heating device (2 2 6) is used to maintain the sample at the desired test temperature, thereby maintaining the constant temperature. Water is pumped through the heating chamber (227). The gap in the test dish is set to a thickness corresponding to the desired wet compression, and is generally 0.2 pSi (about 1.4 kPa). Use shims (2 16) with a size from 0.1 mm to 20.0 mm to set the correct thickness, and use a combination of several shims as needed. At the beginning of the experiment 'the test dish (220) is rotated 90 degrees. (The sample is vertical), and let the test liquid enter slowly from the bottom. This is necessary to ensure that all air is expelled from the sample and the inlet / outlet connections (232/233). Next turn the test dish (220) back to its original position so that the sample (21o) is level. Subsequent particle sequences are the same as previously described for permeability through the plane, that is, placing the inlet tank at the desired height, balancing the flow, and measuring the flow rate and pressure drop. Calculate permeability using Darcy's law. This procedure is also repeated for higher pressures. For samples with very low permeability, it may be necessary to increase the driving pressure, such as by extending the height or by applying additional air pressure to the tank to obtain a measurable flow rate. In-plane material properties can be measured independently by placing the sample in a test dish in both the longitudinal and transverse directions. The general liquid permeability test for alkaline materials can be used to measure the permeability of a porous material as a function of saturation. 4 The principle is similar to the simplified test. The basic difference is that in addition to loading liquid, , --Β Π will load a certain amount of air and produce a fixed saturation.

Description of the invention (71) into' Figure 3 shows the principle and clear explanation of the general permeability through the plane, Figure 4 shows Differences in permeability in general planes. The unmentioned numbers are equivalent to the respective numbers in FIG. 1 (for example, the waste liquid storage tank (3 5 6) corresponds to the waste liquid storage tank (156), etc.). Among them, in addition to the inlet tank (350), the device (3 70) can be used to adjust the height. 'The fixed device (341' not shown in Figure 4) is also used to mount the sample dish (320/420) to the height adjustment device (372). on. This inlet storage tank is relative to the outlet storage tank (354) meaning the first south degree difference (357) ', which is related to the differential pressure Δp (which indicates the pressure difference used to calculate permeability). This inlet tank (350) defines a second height difference (359) with respect to the sample height, which is related to the differential pressure A p (c), and this ap (c) indicates the pressure difference related to the saturation in the sample 'where Higher capillary suction is typically about lower saturation. The real %% begins with a low Δp c (close to the cross-cutting water column) where the sample will be 100% saturated. The liquid flows through the sample due to the applied pressure drop ΔP (c) (the height of the inlet tank_the height of the outlet tank). In steady state, the amount of liquid absorbed in the outlet storage tank is measured as a function of time. Permeability can be calculated from pressure drop and volume ratio data using Darcy's law. The correct saturation can be obtained from the weight of the wet sample after the test compared to the dry sample before the test. For measurements below 100 0 ΰ /. Permeability under saturation, as in the previous paragraph, means that the new test sample will be saturated at 0%. Next move the sample to 軚 β π degrees (for example, 丨 0 cm) and allow it to equilibrate at that height. At this time, the liquid continuously flows from the inlet to the outlet storage tank. Saturation in the sample will decrease over time ^. When steady state is reached, that is, when the graph of absorption versus time is a linear force, the measured flow rate, pressure drop, and saturation are described.

Description of the Invention (72) This procedure is highly repeated for samples. As saturation decreases, it may be necessary to increase the pressure drop between the inlet and outlet tanks to obtain a measurable flow rate. This is because for most porous materials, permeability will decrease rapidly with decreasing saturation. It must be determined that the pressure drop between the inlet and outlet tanks is much less than the capillary suction. Wide liquid reservoirs (352, 354) must be used to ensure that the level does not change significantly while waiting for steady state to be reached. This test can produce permeability to saturation for the desorption cycle, i.e. the sample has a higher saturation at the beginning. Of course, although permeability data 'can be generated for the absorption cycle, it should not be used for this assessment because of some hysteresis effects. The difference between the sample vessel (3 20) for general penetration through the plane and the sample vessel (120) for simplified penetration through the plane is basically that it contains two glasses placed above and below the sample (3 10) Material (335). With regard to frit (3 35), it must be determined that most of the flow resistance is provided by the sample and that the frit resistance is negligible. The microporous film above the coarse material can be measured up to a high height without generating significant flow resistance. The frit should be selected to have a sufficiently high bubble point pressure equivalent to more than 200 cm of water column, but at the same time provide low flow resistance. This can be achieved adequately by selecting a sufficiently thin film with the required bubble point pressure above the more open support structure. For the general-property test, care must be taken to allow air to contact the sample via the side surface ' to visualize Δp (c) to change the Baohe degree. Therefore, the design of the sample dish 4 should be basically the same as the test for simplifying the through-plane test, except that the foam plastic gasket material is removed and the device is generated with a constant pressure, such as a weight ⑴ 7), . 丨, 丄: 21: ^ (CNS) A l {^ ιο χ vy;} ----- I I ----- 111 1 ------- I --------- --- 1 ί Please read the precautions on the back before filling in this page) 449 467 ^ -_ 5 :: ^ 分-" Property Bureau 裒 工 消 消 物-二 ， · ΐ 一 · trJk

Description of the Invention (73) Instead of adjusting the gap between the upper and lower parts, keep the sample under the pressure of $ (from the weight of the upper object (32 1)), unless otherwise Required, otherwise this expected pressure is 0.2 psi (approximately 14 kpa). The sample vessel (42) for the general in-plane permeability test is shown in Figure 4. This design is derived from the simplified in-plane test, and its principle is as explained above. Thus, the fluid enters the sample vessel (420) via the fluid inlet (M2) and the outlet (433) connected to a membrane (435), such as a frit of the type described above (for frit 335). The end of the test sample (41〇) is placed on the two frits, but the center part of 2 inches by 2 inches (approximately 5.1 cm by 5.:! Cm) is not, so it is necessary to avoid redundant samples and films Enemies and gaps. Place the test sample (410) between the upper part and the lower part of the sample dish (420), and use the weight (417) to adjust the pressure for the experiment (unless otherwise required and specified, otherwise 0 2 psi (about kPa)). Further, the sample is maintained at a constant temperature by a heating device (426), for example, by pumping constant temperature water through a heating chamber (427). In addition, for this device, air can enter the sample through the side surface, which is important for changing the saturation. Liquid viscosity Liquid viscosity is an important input parameter for the above determinations, and it should be taken from well-known tables or equations for each mud versus temperature, or measured using accepted measurement procedures.

Devices) (Novato, CA) project 202X4X34N-1D4B-84-P-C-S-E, which can be powered by a motor driven ZETA 6 104-83- 1 35 purchased from CompuMotor (Rohnert, CA). In the case where the data is measured and sent from the actuator 501 and the balance 507, the capillary adsorption and absorption capacity data can be easily generated for each test sample. In addition, the interface from the computer to the actuator 50 can control the vertical movement of the glass frit 502. For example, at each suction height, the actuator can make the glass frit 502 move vertically only after it reaches "balance" (defined below). The bottom of the glass frit 502 is connected to a Tygon® pipe fitting 503, which connects the glass frit 502 to the two-way drainage stop cock 5 0 9 ^ The drainage stop cock 5 0 9 passes through the glass tube 504 and the stop cock 5 I 〇 Instead, it is connected to the liquid storage tank 505. (The stopcock 509 only opens to the drain when cleaning the unit or removing air bubbles). The glass tube 5 11 connects the fluid storage tank 505 to the balance fluid storage tank 506 via the stopcock 5 1 0. The balance liquid storage tank 506 is composed of a lightweight i2 cm diameter glass disk 506A and a cover 506B. The cover 506B has a hole through which the glass pipe 5 11 can contact the liquid in the storage tank 506. The glass tube 5 1 1 must not be in contact with the cover 506B, otherwise unstable balance readings will be produced and the measurement results of the test samples cannot be used. The diameter of the glass frit must be sufficient to accommodate the piston / cylinder device described below for holding the test specimen. The glass frit 502 was mounted on a jacket so that the thermostat could be controlled by a heating tank.

The tea bag is then sealed with a heat sealer. This is called a sample tea bag. An empty tea bag was sealed and used as a blank sample. Then place the sample tea bag and blank tea bag on the surface of the saline solution, and soak it with a spatula for about 5 seconds to make it completely wet (the tea bag will float on the surface of the saline solution, but then it will completely Wetting). Immediately start the timer: After a 20-minute soak time, remove the sample tea bags and blank tea bags from the saline solution and place them in a Bauknecht WS130, Bosch 772 NZK096 or equivalent centrifuge (230 mm diameter) to make each tea The bag is adhered to the outer wall of the centrifugal blue. Close the centrifuge lid, start the centrifuge, and quickly increase the speed to M00 revolutions per minute (1,400 rpm). Once the centrifuge has steadily reached 1,400 revolutions per minute, start the timer. After 3 minutes, stop the centrifuge. Take out the sample tea bag and blank tea bag and weigh them separately. The centrifugal capacity (Dc) of the tea bag of the sample of the absorbent material is calculated as follows: TCC 忖 (weight of the sample tea bag after centrifugation) _ (after centrifugation (weight of dry absorbent material)) A specific part or the entire absorbent article, such as a part of the "cut", is to view a part or the whole of the structure, so at -95 f please read the phonetic on the back?

Description of the invention) The measuring point of the longitudinal axis of the object traverses the entire width of the object. The definition of "" can be used to measure "the volume of the bifurcation area of two legs". Other incisions can be used to determine the "basic capacity", that is, the amount of capacity per unit area contained in a specific area of an object 値). Depending on the size of the unit area (2 cm by 2 cm is better), how much averaging will be defined. Naturally, the smaller the size, the less averaging will be performed. Final storage Multiple methods have been proposed for measuring or evaluating the final storage of absorbent articles. In the case of the present invention, it is assumed that the final storage capacity of the article is the sum of the final absorption capacities of individual cows or materials. For these individual components, a variety of accepted techniques can be applied as long as they are applied consistently throughout the comparison. For example, 'the teabag centrifugal capacity developed for the superabsorbent polymer (SAP) and accepted by everyone is used for this SAp material, but it can also be used for other materials (see above). Once the capacity of an individual material is known, the total object capacity can be calculated by multiplying this amount (ml / g) by the weight of the material used in the object. "For materials with special functions other than the final storage of the adult, such as ° ^^, etc., can be ignored with 'final storage capacity, because this kind of material is compared with special: the final fluid storage material in fact has only very Low capacity 値 or these materials are not intended to carry fluids, so their fluids should be released to other final storage materials.
