Description

Stabilized Absorbent Material for Personal Care Products and Method for Making

Personal care absorbent products include items such as diapers, training pants, sanitary napkins, feminine hygiene products such as panty liners and tampons, incontinence garments and appliances, bandages and the like. The most basic structure of all these products typically includes a bodyside liner, an outer cover and an absorbent core disposed between the bodyside liner and the outer cover. In general, the bodyside liner and outer cover are sealed around to encapsulate the absorbent core, thereby enabling to capture and retain fluid contained within the absorbent core. Depending on the structure of the particular personal care absorbent product, other ingredients may also be included. That is, the product may include such types as elastic side panels, fluid-containing flaps, anchorages, and other layers of fluid transport or retention material.

Previous personal care products were made of materials that were manufactured separately and then joined together to form a laminate. In this case, the boundaries between adjacent layers become somewhat corrugated, which is often indicated by the presence of the adhesive used when fixing the layers together to create a laminate. Separately manufacturing the adhesives that bond the respective layers and laminates together to form a laminate is an expensive procedure requiring many different manufacturing equipment components. This manufacturing method results in a material for personal care products having a pleated contour between each layer at the contact surface or boundary, which may reduce fluid transfer between adjacent layers.

It is therefore an object of the present invention to produce a material for use in a personal care product, without having to perform a number of manufacturing steps. Another object of the present invention is to produce a material for personal care products in which fibers are mixed and entangled with each other so that adjacent fiber layers have indefinite boundaries in order to improve fluid transfer between adjacent layers.

Justice

"Disposable" includes the meaning that it is discarded after use and cannot be cleaned or reused.

"Front" and "back" are used herein to indicate a relationship to the garment itself, rather than to indicate where the garment is taken when the garment is positioned to the wearer.

"Hydrophilic" refers to the fiber or surface of the fiber that is wetted by contacting the aqueous liquid with the fiber. Again, the degree of wetting of the material can be described in terms of the contact angle and the surface tension of the liquid and material involved. Appropriate apparatus and techniques for measuring the wettability of particular fiber materials may be provided by a Cahn SFA-222 surface force analyzer system, or a substantially equivalent system. When measured with this system, fibers with a contact angle of less than 90 ° are called "wettable" or hydrophilic, while fibers with a contact angle greater than or equal to 90 ° are called "non-wetting" or hydrophobic.

"Inner" and "outer" refer to positions relative to the center of the absorbent garment, and in particular to positions transversely and / or longitudinally close to or away from the longitudinal and transverse centers of the absorbent garment.

"Layer" when used alone may have the dual meaning of a single element or multiple elements.

"Liquid" means a non-granular material and / or material that flows and may take the internal form of a container in which it is spilled or placed.

"Liquid delivery" means that liquid can be moved from one layer to another or from one location in another to another.

"Servant" and "cross" have their usual meanings. The longitudinal axis lies in its plane when the product is laid flat and fully unfolded, and is generally parallel to the vertical plane that divides the standing wearer into the left and right body halves when the product is worn. The abscissa is generally located in the plane of the product perpendicular to the ordinate. The article as shown has a longer length in the longitudinal direction than in the transverse direction.

As used herein, the term "particle" refers to such a geometric form, although not limited to spherical grains, fibers or strands, flat or rough surfaces, sheets, ribbons, strings, strands, and the like.

“Spraying” and variations thereof include forcibly releasing liquids as air streams, vortex filaments, or as atomic particles through holes, nozzles, etc., by pressurization, gravity, or centrifugal force of air or other gases.

"Conjugate fibers" refer to fibers formed from at least two polymers extruded from separate extruders but spun together to form one fiber. Conjugate fibers are also sometimes referred to as multicomponent or bicomponent fibers. Although the conjugate fibers may be monocomponent fibers, the polymers are usually different from each other. The polymers are arranged in specific zones located substantially constant across the cross section of the conjugate fibers and extend continuously along the length of the conjugate fibers. The arrangement of such conjugate fibers may be, for example, a seed / core arrangement in which one polymer is surrounded by another polymer, or may be in a side by side arrangement, a pie arrangement or a "depth" arrangement. It may be. Conjugate fibers are described in US Pat. No. 5,108,820 (Kaneko et al.), US Pat. No. 5,336,552 (Strack et al.) And US Pat. No. 5,382,400 (Pike et al.). For bicomponent fibers, the polymers may be present at 75/25, 50/50, 25/75 or any other desired ratio. The fibers may also have the same shape as described in US Pat. Nos. 5,277,976 (Hogle et al.) And US Pat. Nos. 5,069,970 and 5,057,368 (Largman et al.), Which documents describe fibers having an unusual shape. It is incorporated herein by reference.

"Biconstituent fibers" refers to fibers formed from at least two polymers extruded in the same extruder as a blend. The term "compound" is defined as follows. Bicomponent fibers do not have several polymer components arranged in specific regions located relatively uniformly through the cross section of the fiber, and the various polymers are not usually continuous along the entire length of the fiber, but instead are usually microfibers starting and ending randomly. Or to form microfibers. Bicomponent fibers are sometimes referred to as multielement fibers. Fibers of this general type are mentioned, for example, in US Pat. No. 5,108,827 to Gessner. Bicomponent and bicomponent fibers are also described in Polymer Blends and Composites, John A. Manson and Leslie H. Sperling, 1976 Plenum Press All Rights, a division of Plenum Publishing Corporation of New York, IBSN 0-306-30831-2, p. 273-277).

"Airlaying" is a known method by which a fibrous nonwoven layer can be formed. In the airlaying method, a bundle of small fibers having a typical length in the range of about 3 to about 19 mm is separated and incorporated into the air supply and then attached onto the forming screen, usually with the aid of a vacuum supply. The randomly attached fibers are then bonded to each other using, for example, hot air or spray adhesive. Airlaying is described, for example, in U.S. Pat. Reference is made to DE3508344 A1, European Patent Application 85300626.0 and British Patent Application 2,191,793.

"Personal protective product" means diapers, training pants, absorbent underpants, adult incontinence products, bandages and feminine hygiene products.

"Female hygiene" means a sanitary napkin or pad.

"Target site" refers to a site or location on a personal care product where insults are typically delivered by the wearer.

Test Methods

Material Caliper (Thickness) The material caliper is a measure of thickness and measured in millimeters at 0.05 psi using a Starret type bulk tester.

Density of the material by dividing the weight per unit area (grams per square area (gsm)) from 68.9 Pascals to the bulk of the sample (mm) and multiplying the result by 0.001 to convert the value to grams per cubic centimeter (g / cc). Calculate the density. All three samples are evaluated and averaged against the density values.

Personal care absorbent products include items such as diapers, training pants, feminine hygiene products such as sanitary napkins, panty liners and tampons, incontinence garments and instruments, bandages, and the like. The most basic structure of all these products typically includes a bodyside liner, an outer cover and an absorbent core disposed between the bodyside liner and the outer cover. In general, the bodyside liner and outer cover are sealed around them to encapsulate the absorbent core, thereby enabling to capture and retain the fluid contained within the absorbent core. Depending on the structure of the particular personal care absorbent product, other ingredients may also be included. That is, the product may include such types as elastic side panels, fluid-containing flaps, anchorages, and other layers of fluid transport or retention material.

Reference to materials for personal care products can be found in the patent application filed on the same date as this application and co-assigned (agent no. 13303.10). A reference to the method of making the material of Event No. 13303.10 can be found in the co-transferred pending patent application (Agent No. 13817).

The present invention relates to materials for use in personal absorbent articles, which are produced in such a way as to create an unclear boundary or contact surface between adjacent fibrous layers. Previous personal care products were made of materials that were manufactured separately and then joined together to form a laminate. In this case, the boundaries between adjacent fiber layers are somewhat corrugated and clear, which is often indicated by the presence of the adhesive used to fix the layers together to create a laminate.

The material of the invention is preferably prepared according to an airlaying method, in which the fibers are suspended and transported in a gas stream, preferably air, and adhered onto a substrate to form a layer. The material of the present invention consists of a plurality of layers attached in sequence. Sequential attachment of these materials is possible in a multi-bank airlaying method. In this way, the fibrous layers are not produced separately, stabilized separately and then taken together to form a laminate, but one layer is produced over one layer. Of course, although the entire material must be stabilized in some way, the individual layers of the invention need not be so. Stabilization is achieved through the use of a binder, and if thermally activated, there is a clear need for heat treatment of the material after fiber attachment.

Each of the fibrous layers of the material of the invention has fibers mixed and entangled with fibers of adjacent layers as a result of the airlaying method. By the absence of adhesive between the side and adjacent layers of this airlaying, the boundary or contact surface between adjacent layers is not creased or clarified but is unclear.

The manufacture of the material via the multi-bank airlaying method is much more cost effective than the method of making the individual layers and then combining them to produce a laminate, thus lowering the price for the ultimate consumer.

The material of the present invention has a bodyside layer, optionally a fluid transport layer, a fluid retention layer and a garment side layer. The material may also have a distribution layer or any other layer for providing a particular function.

The bodyside layer is sometimes referred to as a bodyside liner or topsheet. In the thickness direction of the product, the liner material is a layer on the wearer's skin, ie the first layer in contact with liquid or other emissions from the wearer. The liner is also for isolating the wearer's skin from the liquid retained in the absorbent structure and should be compliant, soft to the touch and non-irritating.

The bodyside liner may, for example, have a basis weight ranging from about 10.0 grams per square meter (gsm) to about 100 gsm and a density of about 0.05 grams per cubic cm (g / cc) to about 0.5 g / cc. The bodyside liner comprises synthetic fibers and a binder in a ratio of about 90/10 to 0/100, more particularly about 50/50 to about 20/80, and even more particularly about 30/70. It should be noted that binder fibers, rather than liquid binders, are preferred, especially in the case of having a binder of 10% or more.

The bodyside liner may be surface treated with a selected amount of surfactant, such as about 0.28% Triton X-102 surfactant, or otherwise processed to impart the desired level of wetting and hydrophilicity. If a surfactant is used, it may be an internal additive or may be applied to the layer by conventional means, such as spraying, brush coating or the like, prior to the attachment of the layer.

The fluid retention layer used in the present invention must absorb liquid from adjacent bodyside layers in a controlled manner that allows the liquid to be stored without contacting the body. Suitable retention materials for such applications should have a basis weight of about 50 to about 250 gsm and a density of about 0.05 to about 0.5 g / cc. Retaining materials include binders, synthetic fibers, and natural fibers. The binder should be present in an effective amount, generally in an amount of about 3 to 15 weight percent, more particularly about 10 weight percent. Synthetic and natural fibers, excluding the binder, may be present at a ratio of about 0/100 to about 50/50, more particularly about 10/90 to 20/80, even more particularly about 40/60. While any of the layers of the present invention may optionally contain a superabsorbent, the fluid retention layer is the most logical layer to contain such components. This layer may contain 0 to 85% by weight of superabsorbent, which should be included as natural fiber in the calculation of the proportion of materials present.

Although any number of layers can be formed according to the invention, a further useful layer is the second retention layer. This second retention layer is interposed between the first retention layer and the garment side liner and may contain an effective amount of binder and about 75% natural fibers and about 25% superabsorbent fibers, excluding the binder. As indicated above, the superabsorbent should be considered natural fiber in the calculation of the fiber ratio in the layer, where the ratio of synthetic fiber to natural fiber is 0/100 except for the binder.

The garment side liner layer, also referred to as the backsheet or outer cover, is the layer furthest away from the wearer. The outer cover is traditionally formed from a thin thermoplastic film such as polyethylene film, which is substantially impermeable to liquids. The outer cover serves to prevent body secretions contained in the absorbent structure from soaking or contaminating materials that come into contact with the wearer's clothing, bedding or other personal care products. The outer cover may be, for example, a polyethylene film having an initial thickness of about 0.012 millimeters (0.5 mil) to about 0.12 millimeters (5.0 mil), but the outer cover is preferably made as an integral part of the material of the present invention. In this case, the garment liner or outer cover has a basis weight of about 10 to about 100 gsm and preferably comprises synthetic fibers and binders in a ratio of about 50/50 to about 0/100.

The outer cover may be embossed and / or mat finished to provide a more aesthetically pleasing appearance. Other alternative structures for the outer cover include fiber fabrics or nonwovens constructed or treated to impart the desired level of liquid impermeability, or include laminates formed from fabrics or nonwovens and thermoplastic films. The outer cover may optionally be comprised of a vapor or gas permeable microporous "breathable" material, which is permeable to vapor or gas but substantially impermeable to liquids. The air permeability can be applied to the polymer film by, for example, using filler in the film polymer formulation, extruding the filler / polymer formulation into the film and then stretching the film sufficiently to create voids around the filler particles, thereby forming a breathable film. Can be given. In general, the more filler used and the higher the degree of stretching, the greater the degree of breathability. The back may also function as a mating pair of mechanical fasteners, for example when the nonwoven is an outer surface.

Any fluid transfer layer, also referred to as a surge layer, is most typically inserted between and delivers liquid in intimate contact with the bodyside liner and other layers such as fluid distribution or retention layers. The fluid transport or surge layer is generally capable of moving the fluid through itself towards the garment in the Z-direction, ie away from the body side. The surge layer is generally below the inner (unexposed) surface of the bodyside liner. The surge layer preferably has a density of about 0.05 g / cc to about 0.5 g / cc and a basis weight of about 10 to about 100 gsm. The surge layer may be a layer composed of synthetic fibers, binders and natural fibers, wherein the binder is present in an effective amount and the synthetic and natural fibers, with the exception of the binder, are present in a ratio of about 40/60 to about 10/90.

Any distribution layer may be embedded over the fluid retention layer (in the wearer's direction) and be able to move the fluid from the initial deposition point to the point at which storage is desired. Thus, the fluid distribution layer moves the fluid in the X and Y directions, in addition to being able to move the fluid through itself in the Z-direction. Distribution should generally occur at an acceptable rate so that a target attack site, such as a crotch, is ready for subsequent insults. The time between inserts can generally be from several minutes to several hours depending on the wearer's age and the corresponding personal care product. In order to achieve this carrying function, the distribution layer must have a high capillary tension value. Capillary tension in the distribution material is simply measured by the equilibrium vertical wick of 8.5 g / l saline solution and should be at least 15 cm. The wick test is performed by placing the tip of the material vertically in the saline solution, waiting for the solution to equilibrate, and then measuring the height reached. The material of the distribution layer may be made from synthetic and natural fibers with a small amount of binder.

Synthetic fibers include nylon, polyethylene terephthalate, rayon, polyolefins such as polypropylene, fibers made from lyocell regenerated cellulose, and other suitable synthetic fibers known to those skilled in the art. Such synthetic fibers may include staple or other length conjugates, biurea and homopolymer fibers and mixtures of these and other types of fibers. Synthetic fibers may also include a cosmomote for product degradation as mentioned below.

Natural fibers include cellulose such as wood pulp, cotton and the like. Pulp is a standard softwood fluff grade, such as Kimosaly-Clark Corporation's Coosa Mills CR-1654, a high grade available from the Weyerhaeuser Corporation of Tacoma, WA. Bulk additive formaldehyde-free pulp (HBAFF), crosslinked southern softwood pulp fibers with improved wet modulus, and chemically crosslinked pulp fibers such as Weihauser NHB 416. HBAFF is subjected to chemical treatments to impart curl and twist as well as to impart dry and wet stiffness and resilience to the fibers. Another suitable pulp is Buckeye HP2 pulp, and another suitable pulp is IP Supersoft from International Paper Corporation. Suitable rayon fibers are 1.5 Denier Merge 18453 fibers from Coutarulds Fiber Incorporated of Axis, Alabama, Asics, Alabama.

The binder includes fibers, liquids or other binder means that may be thermally activated. Examples of binders include conjugate fibers and liquid additives of polyolefins and / or polyamides. Many suitable binder fibers are known to those skilled in the art and are made by many manufacturers, such as Chisso and Hercules Inc., but one suitable binder is Trevira Inc. (Formerly Hoechst-Celanese) (Sea Core Conjugate fiber available under the trade name T-255 from North Carolina 28145-0004 Salisbury PO Box 4). Another suitable binder fiber is made from Danaklon a / s, located in Engdraget 22, KD-6800 Varde, Denmark, cut to 6 mm length. 2 denier conjugated PE / PP seed / core fibers. A suitable liquid binder is the Kymene ^(R) 557LX binder, available from Hercules Incorporated, Wilmington, Delaware.

Superabsorbents are AFA-94-21-5 from The Dow Chemical Company, Midland, Michigan, AFA-130-53C from Dow Chemical Company, W77553 from Stockhausen or Favor 870 from Stockhausen, and Trevi Sanwet IM 1500 from Laincorporated.

There is a growing interest in producing personal protective products that can be "pourable" or disposed of in conventional toilets and are safe for decay or fat disposal systems. One way to increase the biodegradability of personal care products is to manufacture products that readily degrade under the conditions present in such systems. There are a number of mechanisms that lead to this result, but most are inadequate or unreliable and eventually fail with improper or excessive time requirements before the product disintegrates.

One mechanism that can be used to induce water-degradability within an acceptable time frame is ion sensitivity, wherein the term "ion" refers to a group of atoms or molecularly bonded atoms in the conventional sense that gain or lose one or more electrons. And eventually have a negative or positive electron charge. Certain polymers have the acid held together by a hydrogen bond-containing components ^- base (R-COO). In the dry state, these polymers remain solid. In aqueous solutions with relatively high ionic concentrations, such as urine, the polymers are still relatively intact. However, when the same polymers are exposed to a large amount of water with a reduced ionic content that can be found in the toilet, the ion concentration decreases and the hydrogen bonds begin to break. As this occurs, the polymer itself begins to decompose in water. Materials having this feature are known as cosmomotrovs. See US Pat. No. 4,419,403 to Varona, which is incorporated herein by reference in its entirety.

In conjugate fibers, for example, the first component polymer that is stable in a high ion concentration solution environment (eg, infant or adult urine and menstruation) is the same as supplied by Eastman Chemical Company of Kingsport, Tennessee. Sulfonated polyesters encoded with AQ29, AQ38 or AQ55. Eastman AQ38 polymer consists of 89 mol% isophthalic acid, 11 mol% sodium sulfoisophthalic acid, 78 mol% diethylene glycol and 22 mol% 1,4-cyclohexanedimethanol. It has a nominal molecular weight of 14,000 Daltons, an acid value of less than 2, a hydroxyl value of less than 10 and a glass transition temperature of 38 ° C. Other examples may be a blend of poly (vinyl alcohol) or copolymers of poly (vinyl alcohol) combined with polyacrylic acid or methacrylic acid, or polyvinylmethyl ether combined with polyacrylic acid or methacrylic acid. Eastman polymers are stable in high ionic liquid environments, but are easily degraded in the toilet water during the process of flushing the toilet water (excess water) and thus reducing the ion concentration. Eastman polymers may also be blended with high component melting point second component polymers such as polyethylene.

Other first component polymers that are stable at high ionic concentrations include “induced water-dispersible polymers”. This means that when the first component of the conjugate fiber is exposed to a triggering component, such as sulfate ions or chloride ions, for example at the first concentration level found in normal tap water, the polymer forming the first component will disperse or It means to disintegrate. However, when the first component of the conjugate fiber is exposed to the same trigger component at the second high concentration level typically found in body fluids such as infant or adult urine or menstruation, the polymer forming the first component remains stable and does not disperse. . Suitable examples of such first components are water-dispersible polyester or polyamide polymers, or copolymers, such as copolys, available under the trade names 70-4395 and 70-4442 from the National Starch and Chemical Company. Ester polymers. Conjugate fibers with the first component, including the induced water-dispersible polymer, are not sensitive to the presence of specific triggers at concentration levels found in urine or menstruation, but are typically found in excess of tap water, such as found in toilets. The different low concentration levels are sensitive to the same trigger component and are dispersed within a period of no more than 30 minutes in the presence of the component. That is, the fibrous web formed from or comprising the induced water-dispersible polymer is, in terms of dispersibility, unaffected when attacked with body fluids such as urine or menstruation, but is not affected by the conjugate fibers when disposed in ordinary tap water. As the first component disperses, it tends to decompose.

Furthermore, it is preferable to emboss the whole material from the bodyside liner side preferably. Embossing may be weak enough to emboss only the bodyside liner, or may also include any fluid delivery and distribution layer and fluid retention layer. Embossing patterns can be chosen to maximize material densification, which increases fluid uptake and dispersion throughout the product and fluid distribution along the fore and aft axis. Embossing can also provide the wearer with a visual indication that the product capacity is at its highest and should be discarded, and can also be used to provide an aesthetic benefit. Examples of suitable embossing patterns are shown in the figures. 1 is an embossing pattern for a personal care product called a sinusoidal pattern, and FIG. 2 is an embossing pattern for a personal care product called a shell pattern.

While some embodiments of the present invention have been described in detail above, those skilled in the art will readily appreciate that many modifications are possible in the embodiments without materially departing from the novel teachings and advantages of the invention. Accordingly, all such modifications are understood to be included within the scope of this invention as defined in the claims below. In the claims, the means and functional claims are considered to include equivalent structures as well as structural and structural equivalents described herein as performing the enumerated functions. In other words, although nails and screws may not be structural equivalents in that the nails use cylindrical surfaces to hold the wooden parts together, while the screws use spiral surfaces, the nails and screws are It may be an equivalent structure.

It should also be noted that the patents, applications or publications mentioned herein are incorporated by reference in their entirety.
