Description

Stabilized absorbent material for personal care products and method for making same

field of invention

The present invention relates to the construction of materials in personal care articles such as diapers, training pants, absorbent underpants, adult incontinence products, bandages, and absorbent articles such as feminine hygiene products.

Background of the invention

Personal care absorbent articles include items such as diapers, training pants, feminine hygiene products such as sanitary napkins, panty liners and tampons, incontinence garments and appliances, bandages, and the like. The most basic form of all of these articles generally includes a bodyside liner and an outer cover with an absorbent core disposed between the bodyside liner and outer cover. Typically, the bodyside liner is peripherally sealed to the outer cover so as to enclose the absorbent core so that any fluid can be captured and retained within the absorbent core. Depending on the specific design of the personal care absorbent article, other ingredients may also be included. For example, the article may include other layers such as elastic side panels, liquid barrier sides, fastening means, and fluid transfer and retention materials.

In the past, personal care products have been produced by manufacturing each single-layer material separately and then connecting them into a laminate. In this case, the boundaries between adjacent layers are more defined, often revealing the adhesives used to hold the layers together into a laminate. The method of producing each layer separately and bonding them together into a laminate is an expensive procedure requiring several pieces of different production equipment. This method produces materials for personal care articles that have well-defined boundaries at the boundaries or interfaces between each layer, reducing fluid transfer between adjacent layers.

It is therefore an object of the present invention to produce a material for personal care products which does not require multiple production steps to make. Another object of the present invention is to produce a material for personal care products in which adjacent fibrous layers have indistinct boundaries, with fibers that intertwine and entangle with each other, thereby improving fluid transfer between adjacent layers.

Summary of the invention

The objects of the present invention are achieved by a material for a personal care product comprising: a bodyside layer having a basis weight of about 10 to about 100 gsm and a density of about 0.05 to about 0.5 g/cc comprising synthetic fibers and/or binder; and a liquid-holding layer having a basis weight of about 50 to about 250 gsm and a density of about 0.05 to about 0.5 g/cc, comprising synthetic fibers, binders and/or natural fibers, any of which The boundary between two adjacent fiber layers is indistinct, wherein the fibers at or near the surface of the adjacent layer are largely intermingled with each other.

The material may optionally include a fluid distribution layer and a fluid transfer layer and a garment side liner. Other optional ingredients include superabsorbents and odor control compounds. These layers may also be embossed for aesthetics and fluid control.

definition

"Disposable" encompasses items that are either discarded after use (disposable) or not intended to be washed and reused.

"Front" and "back" are used throughout this specification in relation to the article of clothing itself, rather than any position the garment assumes when the garment is on the wearer.

"Hydrophilic" is used to describe a fiber or fiber surface that is capable of being wetted by aqueous liquids that contact the fiber. The degree of wetting of materials can be described by the contact angle and surface tension between the liquid and the material. Suitable equipment and techniques for determining the wettability of particular fiber materials are provided by the Cahn SFA-222 Surface Force Analyzer system, or a substantially equivalent system. When measured using this system, fibers with contact angles of less than 90° are designated as "wettable" or hydrophilic, while fibers with contact angles of 90° or greater are designated as "non-wettable" or hydrophobic.

"Inwardly" and "outwardly" refer to locations relative to the center of the absorbent garment, specifically, laterally and/or longitudinally toward or away from the longitudinal and lateral center of the absorbent garment.

"Layer", when used in the singular, can have the dual meaning, ie, a single element or a plurality of elements.

"Liquid" means a non-particulate material, and/or a material that is capable of flowing and can take the shape of a container into which it is poured or placed.

By "fluid communication" is meant that liquid is able to migrate from one layer to another, or from one location to another within a layer.

"Portrait" and "landscape" have their customary meanings. The longitudinal axis lies in the plane of the article when placed on a flat surface and fully extended, and is approximately parallel to the vertical plane that bisects a standing wearer into left and right body halves when the article is worn on the body. The transverse axis lies in the plane of the article and is approximately perpendicular to the longitudinal axis. The article is drawn longitudinally longer than transversely.

"Particle" in the sense of the present invention means any geometric form such as, but not limited to, spherical particles, fibers or filaments, flat or roughened surfaces, sheets, ribbons, strings, threads, etc.

"Spray" and variations thereof cover a liquid, or a stream in the form of a helical filament, or a stream of micronized particles, which is forced through an orifice, nozzle, etc., by force of air or other gas, gravity, or centrifugal force. The spray can be continuous or discontinuous.

As used herein, the term "conjugate fiber" refers to at least two polymers extruded through separate extruders but spun together to form the same fiber. Conjugate fibers are also sometimes called multicomponent or bicomponent fibers. The polymers used are usually different from each other, although the conjugate fibers can also be monocomponent fibers. These polymers are arranged in substantially fixed and well-defined regions on the cross-section of the conjugate fiber, and extend continuously along the entire length of the conjugate fiber. The configuration (cross-sectional arrangement) of such conjugate fibers may be, for example, a sheath/core arrangement in which one polymer is surrounded by another, or may be side-by-side, fan-shaped, or "sea". -island" arrangement. Conjugate fibers are disclosed in US Patent 5,108,820 to Kaneko et al., US Patent 5,336,552 to Strack et al., and US Patent 5,382,400 to Pike et al. For bicomponent fibers, the polymers may be present in a 75/25, 50/50, 25/75 or any other desired ratio. Such fibers can also have a wide variety of shapes, as seen in US Patent 5,277,976 to Hogle et al. and US Patents 5,069,970 and 5,057,368 to Largman et al. The above patents and applications describing fibers of unconventional shape are hereby incorporated by reference in their entirety.

As used herein, the term "bicomponent fiber" refers to a fiber formed by extruding a blend of at least two polymers from the same extruder. The definition of the term "blend" can be found below. The various polymer components contained in bicomponent fibers are not arranged in relatively fixed regions on the cross-section of the fiber, and the various polymers are usually discontinuous along the entire length of the fiber. Instead, they tend to form randomly and start randomly. Ended microfilaments (fibrils) or native fibrils. Biconstituent fibers are also sometimes referred to as multiconstituent fibers. This broad class of fibers is discussed, for example, in US Patent 5,108,827 to Gessner. Bicomponent and bicomponent fibers are also in the textbook Polymer Blends and Composites, edited by John A. Manson and Leslie H. Sperling, copyright 1976 by Plenum Press, a division of Plenum Publishing Company (New York), IBSN 0-306-30831-2, pages 273-277.

"Airlaid" is a well known method of forming fibrous nonwoven layers. During air-laying, staple fiber bundles, typically between about 3 and about 19 mm in length, are dispersed and entrained by a passing air stream and deposited onto a forming wire, usually with the aid of a vacuum source. The randomly deposited fibers are then bonded to one another by means of, for example, hot air or a spray of adhesive.气流成网例如在下列文献中做了讨论：美国专利4,005,957、4,388,056、4,592,708、4,598,441、4,674,996、4,761,258、4,764,325、4,904,440、4,908,175以及5,004,579,德国专利DE3508344 A1、欧洲专利申请85300626.0以及英国专利申请2,191,793。

experiment method

Material caliper (thickness): Material caliper is the measurement of material thickness, which is measured by Starret type bulkiness tester under the condition of 0.05psi, and the unit is millimeter.

Density: The density of the material is converted to grams per cubic centimeter by dividing the sample weight per unit area, that is, the weight of the sample in grams per square meter (gsm) by the thickness of the sample in millimeters at 68.9 Pa, and multiplying the result by 0.001 Value (g/cc). A total of 3 samples were measured, and the average value was taken as the density value.

Detailed description of the invention

Personal care absorbent articles include items such as diapers, training pants, feminine hygiene products such as sanitary napkins, panty liners and tampons, incontinence garments and devices, bandages, and the like. The most basic form of all of these articles generally includes a bodyside liner and an outer cover with an absorbent core disposed between the bodyside liner and outer cover. Typically, the bodyside liner is peripherally sealed to the outer cover so as to enclose the absorbent core so that any fluid can be captured and retained within the absorbent core. Depending on the specific design of the personal care absorbent article, other ingredients may also be included. For example, the article may include other layers such as elastic side panels, liquid barrier sides, fastening means, and fluid transfer and retention materials.

A discussion of materials for personal care products can be found in Attorney Docket No. 13303.10, filed on the same date as the common assignee of this application. A discussion of methods of making the materials of Case 13303.10 can be found in co-assigned, co-pending Attorney Docket No. 13817.

The present invention is a material for personal care products produced in such a way that the boundaries or interfaces between adjacent fibrous layers are produced indistinctly. Previous methods of manufacturing personal care products have been to manufacture the materials separately and then join them together to form a laminate. In such cases, the boundaries between adjacent fibrous layers are more defined and defined, often marked by the adhesive used to hold the layers together to form a laminate.

The materials of the present invention are preferably produced according to the airlaid process, wherein the fibers are suspended in an air stream, preferably transported in air, and then deposited on a substrate to form a layer. The materials of the present invention consist of multiple layers deposited sequentially. Sequential deposition of such materials can be accomplished by multi-gas flow-laying. In this method, the individual fibrous layers are not manufactured separately, stabilized individually, and then brought together into a laminate, but are formed one on top of the other. Of course, the entire material must be stabilized in some way, but the individual layers of the present invention do not. Stabilization is achieved through the use of a binder which, if of the heat-activated type, obviously requires a heat treatment of the material after deposition of the fibers.

Each individual fibrous layer of the material of the present invention, as a result of the airlaid process, includes some fibers which are intermixed or entangled with the fibers of adjacent fibrous layers. This characteristic of airlaid, together with the general absence of adhesive between adjacent layers, makes the boundary or interface between adjacent layers not sharp and clear, but blurry.

Producing the material by multi-vent airlaying is much more cost-effective than producing the layers separately and then joining them together to form a laminate, thus reducing costs for the end consumer.

The material of the present invention has a body side layer, an optional fluid transfer layer, a liquid retention layer and a garment side layer. The material may also have distribution layers or other optional layers to provide specific functions.

The bodyside layer is also sometimes referred to as the bodyside liner or topsheet. Along the thickness of the article, the liner material is the layer that directly contacts the wearer's skin, and therefore is the first layer that contacts liquids or other exudates from the wearer. The liner acts to insulate the wearer's skin from retaining liquids in the absorbent structure, and should conform to the skin, be soft to the touch, and be non-irritating.

The body side layer may have a basis weight of, for example, about 10.0 g/m ² (gsm) to about 100 gsm, and a density of about 0.05 g/cm ³ (g/cc) to about 0.5 g/cc. The bodyside liner is composed of synthetic fibers and binder in a ratio of about 90/10 to about 0/100, more specifically about 50/50 to about 20/80, and still more specifically about 30/70. It should be noted that it is preferred to use binder fibers rather than liquid binders, especially if the binder content is greater than 10%.

The bodyside liner may be surface treated or otherwise treated with a selected amount of surfactant, such as about 0.28% Triton X-102 surfactant, to impart the desired degree of wettability or hydrophilicity. A surfactant, if used, may be an internal additive, or may be applied by any conventional means, such as spraying, brushing, etc., prior to depositing the next layer.

The liquid-holding layer employed in the present invention must be capable of absorbing fluid from the adjacent bodyside layer in a controlled manner so as to store fluid away from the body. Liquid-holding materials suitable for this purpose should have a basis weight of from about 50 to about 250 gsm and a density of from about 0.05 to about 0.5 g/cc. Liquid-holding materials include adhesives, synthetic fibers, and natural fibers. The binder must be present in an effective amount, generally between about 3-15 wt%, or more specifically about 10 wt%. Excluding binders, synthetic and natural fibers may be present in a ratio of about 0/100 to about 50/50, more specifically about 10/90 to 20/80, more specifically about 40/60. While any layer of the present invention may optionally contain superabsorbent, the liquid-holding layer is the most logical layer to contain such a component. This layer may contain from 0 to 85% by weight of superabsorbent, the amount of which should be counted as natural fibers when calculating the ratio between the materials present.

According to the present invention, any number of layers can be formed, however, a particularly useful additional layer is a second liquid-holding layer. Such a second liquid-holding layer will be inserted between the first liquid-holding layer and the garment side liner and may contain an effective amount of binder, and, not counting binder, about 75% natural fibers and about 25% superabsorbent fibers . It has been pointed out above that superabsorbents should be counted as natural fibers when calculating the fiber ratio in the layer, so in this layer, the ratio of synthetic to natural fibers, excluding binder, is 0/100.

The garment side liner, also known as the back panel or outer cover, is the layer furthest from the wearer (body). The outer covering layer has traditionally been made of a thin thermoplastic film, such as polyethylene film, which should be substantially impermeable to liquids. The function of the outer cover is to prevent bodily exudates contained in the absorbent structure from wetting or soiling the wearer's clothing, bed sheets, or other materials that come into contact with the personal care article. While the outer cladding may be, for example, a polyethylene film having an initial thickness ranging from about 0.5 mil (0.012 mm) to about 5.0 mil (0.12 mm), it is preferred that the outer cladding be made integral to the material of the present invention. part. In this case, it is preferred that the garment side liner or outer cover has a basis weight of about 10 to about 100 gsm, comprising synthetic fibers and binder in a ratio of about 50/50 to about 0/100.

The outer cover can be embossed and/or matte finished to provide an aesthetically pleasing appearance. Other alternative constructions for use as the outer cover include woven or nonwoven webs imparted by fabrication or processing with the desired degree of liquid impermeability, or laminates of woven or nonwoven fabrics and thermoplastic films. The outer cover may optionally be constructed of a vapor or gas permeable, microporous "breathable" material which is permeable to vapor or gas but substantially impermeable to liquids. The air permeability of polymer films can be caused, for example, by adding fillers to the polymer formulation, then extruding the filler/polymer formulation into a film, and then stretching the film sufficiently to form cavities surrounding the filler particles so that The membrane becomes breathable. Generally, the higher the filler level, the greater the degree of stretch, and the greater the degree of breathability. The backing (back panel), in the case of eg a nonwoven as the outer surface, can also function as a cooperating element of the mechanical fastening.

An optional fluid transfer layer, also known as a surge layer, is sandwiched between and in fluid tight contact with the bodyside liner and another layer, such as a fluid distribution layer or a liquid retention layer. The fluid transfer layer or peak layer moves fluid generally in its Z-direction, ie away from the body side and towards the garment side. The peak layer is generally placed adjacently below the inner surface (non-exposed surface) of the bodyside liner. Preferably, the peak layer has a density of from about 0.05 g/cc to about 0.5 g/cc; a basis weight of from about 10 to about 100 gsm. The peak layer may be a layer of synthetic fibers, binders, and natural fibers, wherein the binder is present in an effective amount and, not counting the binder, the synthetic and natural fibers are in a ratio of about 40/60 to about 10/90 ratio exists.

An optional distribution layer may be placed on top of the liquid-holding layer (facing the wearer) and must be capable of transferring fluid from the point of initial deposition to the desired point of storage. Thus, the fluid distribution layer, in addition to allowing fluid to pass through itself in the Z-direction, also allows fluid to migrate in the X and Y directions. Dispensing should be done at an acceptable rate so that the target discharge area, typically the crotch area, has time to prepare for the next incoming discharge. The time between discharges can range from just a few minutes up to several hours, usually depending on the age of the wearer and the particular personal care article. To achieve this transfer function, the distribution layer must have a high capillary tension value. Capillary tension in the dispensing material is simply measured by an equilibrium vertical wicking height of 8.5 g/l saline solution and should be greater than 15 cm. The wicking test method involves placing one end of the material vertically in a saline solution, waiting for the solution to equilibrate, and then measuring the height achieved. The material from which the distribution layer is made can consist of synthetic and natural fibers with a small amount of binder.

Synthetic fibers include those made from nylon, polyethylene terephthalate, rayon, polyolefins such as polypropylene, Lyocel regenerated cellulose, and any other suitable synthetic fibers known to those skilled in the art. Such synthetic fibers may include conjugate, biconstituent and homopolymer fibers, which may be staple or other lengths, and blends of such fibers with other types of fibers. Synthetic fibers may also include kosmotropes for degrading the product, as discussed below.

Natural fibers include cellulose such as wood pulp, cotton, and the like. Pulps include standard softwood staple fiber grades such as Coosa Mills CR-1654 from the Kimberly-Clark Company; High Loft Additive Formaldehyde Free Pulp (HBAFF) from Weyerhaeuser Company (Tacoma, WA), which is a high linked southern softwood pulp fibers; and a chemically crosslinked pulp fiber such as Weyerhaeuser NHB416. HBAFF has a chemical treatment agent that fixes crimp and twist, and it also imparts additional dry and wet stiffness and resilience to the fiber. Another suitable pulp is Buckeye HP2 pulp, and yet another is IP Supersoft, available from International Paper Company. A suitable rayon fiber is 1.5 denier, Lot No. 18453, available from Courtaulds Fiber Company (Axis, Alabama).

Adhesives include fibrous, liquid, or other heat-activatable bonding means. Exemplary adhesives include polyolefin and/or polyamide conjugate fibers and liquid adhesives. One suitable binder is sheath/core conjugate fiber available from Trevira Corporation (formerly Hoechst-Celanese) (PO Box 4, Salisbury, NC 28145-0004), trade designation T-255, but those skilled in the art Many suitable fibers are also known and manufactured by, for example, Chisso and Hercules. Another suitable binder fiber is manufactured by Danaklon Corporation, Engdraget 22, KD-6800 Varde (Denmark), which is a 2 denier conjugated PE/PP sheath/core fiber with a cut length of 6 mm. A suitable liquid adhesive is Kymene(R) 557LX adhesive, available from Hercules Corporation (Wilmington, DE).

Superabsorbents include AFA-94-21-5 from Dow Chemical Company (Midland MI); AFA-130-53C from Dow Chemical; W77553 from Stockhausen or Favor 870 from Stockhausen and Sanwet IM 1500 superabsorbent from Trevira Corporation produced.

Currently, there is a growing interest in producing personal care products that are "flushable," or that can be dropped into a conventional toilet and are safe for septic or municipal wastewater treatment systems. One approach to improving the biodegradability of personal care products is to produce a product that will disintegrate rapidly under the conditions present in such systems. There are multiple mechanisms that can cause this, but most are inappropriate or unreliable, causing the product to fail due to improper timing, or it takes an unduly long time for the product to disintegrate.

One mechanism that can be used to induce water degradability within acceptable time limits is ion sensitivity, where the term "ion" means an atom or molecularly bonded group of atoms that gains or loses one or Multiple electrons, thus carrying a negative or positive charge. Certain polymers contain acid group (R-COO-) components that are held together by hydrogen bonds. In the dry state, these polymers remain solid. In aqueous solutions with higher ionic concentrations, such as urine, the polymer remains relatively unchanged. However, when the same polymer is subsequently exposed to larger quantities of water with a low ion content, such as that found in toilet bowls, the concentration of ions decreases and the hydrogen bonds begin to break down. When this happens, the polymer itself will start to disintegrate in water. Materials with such properties are called kosmotropes. See, eg, US Patent 4,419,403 to Varona, which is hereby incorporated by reference in its entirety.

For example, in conjugate fibers, the first component polymer is stable in high ion concentration solution environment (such as infant or adult urine and menses), which can be sulfonated polyester AQ29, AQ38 or AQ55, manufactured by Eastman Chemical Company (gold Fort, Tennessee). Eastman AQ38 polymer is composed of 89 mol% isophthalic acid, 11 mol% sodium sulfoisophthalate, 78 mol% diethylene glycol, and 22 mol% 1,4-cyclohexanedimethanol. It has a nominal molecular weight of 14,000 Daltons (D), an acid value of less than 2, a hydroxyl value of less than 10, and a glass transition temperature of 38°C. Other examples include blends of polyvinyl alcohol or polyvinyl alcohol copolymers with polyacrylic acid or polymethacrylic acid, or polyvinyl methyl ether with polyacrylic acid or polymethacrylic acid. Eastman series polymers are stable in high ionic solution environments, but will disintegrate rapidly in toilet water where flushing (large volumes of water) reduces the ionic concentration. Eastman polymers can be paired with higher melting temperature range 2nd component polymers such as polyethylene.

Other 1st component polymers that are stable at high ionic concentrations include "()mutagenic water dispersible polymers". This means that when the first component of the conjugate fiber is exposed to a mutagen component, such as sulfate ion or chloride ion, at a first concentration of the ion at the level of ordinary tap water, the polymers making up the first component will Disperse or disintegrate within no more than 30 minutes. However, when the conjugate fiber first component is exposed to a second, higher concentration level of the same mutagen component typically found in, for example, infant or adult urine or menses, the polymers that make up the first component remain stable And don't scatter. Suitable examples of such first components include water dispersible polyester or polyamide polymers or copolymers such as the copolyester polymers available from National Starch and Chemical Company, Product Designations 70-4395 and 70-4442. Conjugate fibers having a first component comprising a mutagenic, water-dispersible polymer are insensitive to a particular mutagen component at concentrations normally found in urine or menses, however when the same mutagen component is present but Its concentration is at different, lower levels, typical values such as in large quantities of tap water, such as in toilets, are highly sensitive and disperse within no more than 30 min. Thus, webs that are or incorporate mutagenic, water-dispersible polymers are unaffected in their dispersibility when exposed to bodily fluid discharges, such as urine or menses, but are not affected when placed in ordinary tap water. With the dispersion of the first component of the conjugate fiber tends to disintegrate.

It is also preferred that the entire material is embossed, preferably from the body side lining side. The embossing effect can be so light that it is limited to the bodyside liner, or an optional fluid transfer layer and liquid holding layer can be included. The embossing pattern should be chosen to achieve maximum densification, which will improve fluid intake and distribution throughout the product, as well as fluid distribution along the front-to-back axis. Embossing can also provide a visual signal to the wearer that the article is nearing capacity and should be discarded, and can also be used to provide an aesthetic benefit. Examples of suitable embossing patterns are shown in the accompanying drawings. Figure 1 is an embossed pattern for a personal care product known as a sine wave pattern; Figure 2 is an embossed pattern for a personal care product known as a seashell pattern.

Although the above has only been described in detail with respect to a few exemplary embodiments of the present invention, those skilled in the art will readily appreciate that, on the basis of these exemplary embodiments, without departing from the novel teachings and advantages of the present invention, further Many modifications were made. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the following claims. In the claims, means-plus-function requirements are intended to cover the described structures as performing the recited function and not only structural equivalents but also equivalent structures. For example, although nails and screws are not structural equivalents in the sense that nails take a cylindrical surface to hold wooden parts together and screws use a helical surface, nails and screws can regarded as equivalent structures.

It should be further noted that any patent, application or publication cited herein is hereby incorporated by reference in its entirety.
