Nr.387310

The invention relates to absorbent products, u.zw. in particular those worn by the user against the body and intended to absorb body exudates, eg diapers, sanitary napkins, tampons, etc.

Such products generally comprise an absorbent element such as a filling or core of absorbent material, including wood pulp, which is optionally encased in a cover sheet which is permeable to body exudate, at least on the body-contacting side. Often, for example, disposable diapers and some sanitary napkins, the off-page is provided with a barrier (sealing) foil, ie a film of a body fluid impermeable material to protect the clothes of the user. This barrier film may form part of the cover layer surrounding the absorbent material or may be located on the far side of the body under this cover layer.

By and large, such products have fulfilled their main function, that is, they have absorbed and retained the body fluid. However, a major drawback of such products is that after being worn by the user for a while and before they have become completely saturated, the products have become inoperable due to the fluid striking an outer surface in contact with the user's laundry, or that the surface carried against the body becomes so wet with fluid that the user, due to the discomfort associated therewith, is prompted to discard the product. There is therefore a need for an absorbent product in which the intended absorbent material is fully utilized and the absorbent fluid is kept away from the outer surfaces of the product.

One attempt to solve this problem is described in U.S. Patent Nos. 3,017,304 and 3,612,055, in which there is provided on the body-distal side of the product a skin or layer which serves to withdraw the liquid from the proximal side. Unfortunately, as such, this skin has only a low retention capacity for liquids and soon becomes saturated and ineffective. After the US-PS no. No. 4,047,531 describes, as a proposed solution to this problem, a layer structure comprising superimposed layers of relatively hydrophobic and hydrophilic wood pulp. Unfortunately, the use of relatively hydrophobic material tends to reduce the overall absorbency of the product, which also does not provide a satisfactory solution. Therefore, no satisfactory product has yet been found which could meet the demand for an absorbent product which absorbs as much fluid as conventional products, or more fluid than these, but which keeps the absorbed fluid away from the outer surfaces of the product.

According to the invention, there is provided a body fluid absorbing product which is at least as absorbent as common products and also has the property of retaining a major portion of the absorbed fluid in an inner layer and which counteracts the tendency of fluid on the surface of the product or accumulates near this surface. In particular, the invention relates to an improved absorbent product, eg in the form of a disposable diaper, sanitary napkin or tampon, having a plurality of differently absorbent layers and containing wood pulp as the absorbent material, and characterized by an absorbent element consisting of a plurality of absorbent layers and at least one first absorbent layer and a second comprising absorbent layer adjacent thereto, wherein the first layer comprises cellulosic fibers and the second layer comprises a mixture of peat and finely ground mechanical wood pulp in a weight ratio of at least 0.35 g of the mechanical wood pulp per g of peat and a maximum of 50% mechanical wood pulp by weight of the second Layer, and the milled wood pulp has a CSF (Canadian Standard Freeness) value of 30 to 600, and wherein the second layer preferably absorbs at least about twice the weight of the fluid as the first layer.

Preferably, at least 0.4 g of finely ground wood pulp per g of peat is present in the second absorbent layer. Such finely ground mechanical wood pulp may be selected from materials such as ground wood pulp, refiner wood pulp or thermomechanical wood cell pulp. The particle size of the mechanical wood pulp is determined by the standard Canadian Roughness or the degree of milling (Canadian Standard Freeness, measured by TAPPI method T-227, hereinafter referred to as CSF). As already stated, the mechanical wood pulp has a CSF value of from 30 to 600, in particular from 60 to 300. The second layer may also contain longer fibrous absorbent materials, such as chemical wood pulp and / or rayon. Preferably, the peat is bleached to a brightness of at least about 70 as measured on a Hunter Color Scale System C type apparatus. This second layer has the property of retaining at least about twice the weight of fluid absorbed as compared to the first layer before the product becomes nonfunctional.

Preferably, the absorbent structure of the invention further comprises at least a third layer of cellulosic fibers. Preferably, the peat containing second layer is between the first and third layers to form an inner layer of the absorbent structure. Because of the excellent ability of the inventive structure to preferentially retain the absorbed fluid in the second layer, fluid is kept away from the outside and thus from the outer surfaces of the absorbent element. Surprisingly, this effect is achieved by the use of a material, namely peat, which in itself has no greater absorption capacity for fluids than ordinary wood pulp, is economical, and yet leads to the desired result in an original way.

In one embodiment, the absorbent element according to the invention is incorporated into a sanitary napkin, which also has a fluid-permeable cover layer of a non-woven fabric and optionally an impermeable barrier film. The excellent preferred retention of the fluid in the second layer, as compared to the first and third layers, keeps both the proximal surface and the near-wash surface relatively dry and increases

Comfort for the user and the life of the product.

In a second embodiment, the absorbent element is incorporated in a tampon in which it is preferred by the original construction of the element to that mentioned above

Liquid retention in the middle layer will allow the tampon to fill from the center out, thereby increasing the useful life of the tampon and reducing the tendency for fluid to ooze around an externally saturated tampon.

In another embodiment, the absorbent element is incorporated into a disposable diaper, again with the preferred liquid retention feature keeping both the body-proximate surface and the near-wash surface of the product drier and increasing the useful life of the product.

FIGS. 1 and 2 show, as a perspective view and a cross section, respectively, a sanitary napkin which contains a structure according to the invention as the absorbent element. The sanitary napkin -10- comprises an absorbent element -12- which is enveloped by a fluid-permeable cover layer -14- which consists of any woven material or of a non-woven material

- 4 Nr.387310, which is permeable to the body fluid impinging on the surface of this layer. Such cover layers are well known to those skilled in the art. On the side of the napkin proximate to the body, a fluid-impermeable barrier film 16 is provided which lies between the cover layer 14 and the element 12. The barrier film prevents the fluid from entering the undergarment and may be formed of any thin, flexible body fluid relatively impermeable material, eg, a polymeric film such as polyethylene, polypropylene, cellophane, or any of the commonly used , Fluid permeable material which has been treated in such a way that it becomes impermeable, eg an impregnated, fluid repellent paper. The illustrated napkin is of such type that it is attached to the user's undergarment by adhesive. For this purpose, the wäs chenahe side of the napkin is provided with an extending in the longitudinal direction of the binding element of pressure-sensitive adhesive -18-. A protective strip -20- is provided which overlies the adhesive element -18- and serves to cover the adhesive element before use.

According to the invention, the absorbent element -12- consists of a plurality of absorbent layers. A first layer comprises cellulose fibers and may be, for example, loosely bonded fibers of wood pulp, regenerated cellulose, cotton fibers or chemically or physically modified cellulose fibers such as alkyl carboxyl cellulose, cellulose grafted-on groups or the like. contain. In an alternative embodiment, the first layer may also take the form of a more ordered configuration of cellulosic fibers, eg, it may be a wadded tissue paper or other bonded structures. Next to this first layer -22-, and in coincidence with it, is a second layer -24-. This second layer comprises, in admixture, peat and finely ground mechanical wood pulp in a weight ratio of at least about 0.35 g of mechanical wood pulp per gram of peat. Preferably, at least 0.4 g of finely ground mechanical wood pulp is present per gram of peat. Such finely ground mechanical wood pulp may be selected from materials such as ground wood pulp, refiner wood pulp and thermomechanical wood pulp. Ground wood pulp consists essentially of trees and twigs, which are debarked, cleaned and then ground into small particles, Refiner wood pulp differs from ground wood pulp only in that when grinding a refiner, ie a disc-like device is used which is well known to those skilled in the art and which generally has metal ribs at its circumferentially located portions which last contact the wood particles and help to separate the wood fibers without unduly damaging them. Thermomechanical wood pulp is the same as refiner pulp, but the wood particles are heated during their stay in the refiner, usually with steam, this heating further helping to separate the wood fibers. The common feature of these mechanical pulps is that no attempt has been made to separate the fibers by chemical means, although later, once the fibers have been comminuted to a fine particulate material, they may be subjected to chemical treatment, for example by bleaching.

The particle size of the mechanical wood pulp can be characterized by the CSF (see above). Preferably, mechanical wood pulp has a CSF value of 30 to 600, especially 60 to 300. The second layer may also contain longer fiber absorbent materials such as chemical wood pulp and / or rayon. Preferably, the peat is bleached to a brightness level of at least about 70 as measured on a Hunter Color Scale System C scale.

Preferably, the peat is uniformly dispersed in the second layer and has been bleached or otherwise processed to achieve the specified whiteness. Sphagnum moss of this whiteness can be easily produced by the process of bleaching peat moss. In this method, the starting material is sphagnum-type peat which is capable of retaining at least about 15 times, preferably about 20 times, its weight in water. The peat is sieved through sieves with a mesh size of 1.8 mm (10 mesh) or with a mesh size of 0.149 mm (100 mesh). The material on a sieve with a light

Nr.387310

- 5 mesh of 1.8 mm remains, u.zw. primarily roots and branches, is thrown away. Likewise, the material passing through the 100 mesh sieve, namely the fines which are scarcely contributing to absorption and very difficult to bleach, is discarded. The peat used as the starting material therefore has a particle size of about 0.15 mm (100 mesh) up to about 1.8 mm (10 mesh). The peat is bleached by treatment with both chlorine and calcium in the form of limestone. The bleaching process can be carried out in batch mode; that is, the peat is diluted with water to a concentration of about 2% by weight, then treated with chlorine and then with calcium carbonate, and finally washed with acid and with water to achieve the desired whiteness.

Preferably, the finely ground mechanical wood pulp as a component of the second layer and optionally the long fiber absorbent material such as rayon and / or chemical pulp (eg Kraft or sulfate pulp) is added to the still wet, bleached peat. The mixture is then slurried and made into a cardboard. The paperboard is then dried and ground to form the absorbent second layer.

The components of this second layer may be present in loosely connected form, u.zw. of the kind obtained by methods of making absorbent fillings well known to those skilled in the art. It has been found that the presence of the finely ground mechanical wood pulp imparts a substantial degree of integrity to the second layer. In addition, the components can be stabilized using adhesive binders so that this layer obtains even greater structural integrity. In the illustrated embodiment, a third layer is also provided -26-, which consists of the same material as the first layer.

It has been found that the sanitary napkin of Figures 1 and 2, which contains a structure according to the invention, has the surprising property that, before it is completely saturated, it preferably retains liquid in the layer -24-. In other words, it has been found that the body fluid impinging on the proximal surface of the napkin neither remains on that surface nor is distributed evenly throughout the absorbent element. Rather, a disproportionate amount of the ingested amount of body fluid is retained in the second layer of the structure. Preferably, this layer retains at least about twice as much absorbed fluid weight as any other layer, such as layer -22 or layer -26-. In particular, this layer retains at least 2.5 times as much. This result is obtained regardless of whether the relative weight of the second layer according to the invention is greater than or equal to the weight of the first layer or not. This is particularly surprising insofar as, for example when using a layer of wood pulp as a first layer and a layer comprising 30 wt .-% bleached sphagnum peat, 38 wt .-% milled wood pulp, 8 wt .-% Kraft wood pulp and 24 wt .-% rayon fibers, at Saturation retained amount of water from each of these layers, each measured by itself, is substantially equal. Nevertheless, in combining these layers to form the multi-layered structure of the present invention, the aforementioned preferred retention of liquid is achieved.

Although the preferred retention occurs over a wide range of relative weights of the first and second layers of the inventive structure, preferably the weight of the first layer is about 0.1 to about 2.0 times, preferably about 0.5 to about about 10 times the weight of the second layer. If this weight ratio is too small, then the protective effect of the first layer is unfavorably reduced. However, if this ratio is too large then the effect of preferred restraint is minimal to negligible because the second layer will soon be saturated.

Figures 3 and 4 show another embodiment of the sanitary napkin -28- containing the structure according to the invention. As in the embodiment described above, the sanitary napkin -28- comprises an absorbent element -30- which is enveloped by a fluid-permeable cover layer -32-, which may be made of a woven material or of a non-woven material. Between the cover layer -23- and the element -30- is a fluid-impermeable barrier film -34-, which serves to protect the laundry of the wearer.

- 6 Nr.387310

The barrier film -34- overlies the near-wash major surface of the absorbent element -30- as well as over the side surfaces and over the extreme longitudinal portions of the body-proximate major surface of the element -30-. The illustrated napkin is of the type which is secured in the crotch area to the wearer's undergarment by adhesive. The napkin is therefore provided with a pressure-sensitive adhesive on its main surface near the wash, which is covered by a peel-off protective strip.

As in the embodiment described above, the absorbent element is composed of the first, second and third layers -40, 42, 44-, which layers are superimposed on each other. In this bandage -28- are the first and third layer -40 or 44- is formed of a generally rectangular sheet product of bonded wood pulp fibers which has been folded into a C-shape in such a way that the portions adjacent each longitudinal edge are folded against each other so that they collide and overlie the center portion of the sheet product. In this embodiment, the second layer comprises a mixture of peat and ground mechanical wood pulp in the proportions mentioned in connection with the first described embodiment, these components being bonded together to form a dimensionally stable second layer. This second layer is between the first and third layers -40 and 44-. This construction also has the preferred liquid retention described above.

Figures 5 and 6 show a disposable diaper -46- containing the inventive structure. The diaper comprises an impermeable wrap -48, which is also preferably a film here, and a permeable cover layer -50- comprising a nonwoven fabric, a spunbonded fabric, a permeable sheet material or the like. can be. In the illustrated embodiment, the cover layer and the cover are the same size and are sealed together at their edges. Between the cover layer and the cover there is an absorbent element -52- according to the invention. The absorbent element 52- is smaller than the cover sheet and the cover and is disposed within the edges of the latter two layers. The absorbent element comprises a first layer 54- which lies adjacent to the cover layer 50 and contains long fiber wood pulp. A second layer -56- is provided which contains peat and ground wood pulp according to the invention and corresponds to the conditions stated in connection with the second layer according to FIG. The opposite side edges of the diaper are provided with adhesive strips 58 which serve to secure the diaper to the user. In use, this construction demonstrates the preferred restraint described above and tends to keep the absorbed liquid away from the cover sheet.

FIGS. 7 and 8 show a tampon blank -60- and a finished tampon -62-, each containing a structure according to the invention. The tampon blank is provided with a generally rectangular first layer 66 of a structure according to the invention, this layer 66 consisting of a film of wood pulp fibers. Over this first layer -66- is a second layer -64- which consists of the above-described mixture of peat and ground mechanical wood pulp. The blank is deformed into a cylinder by rolling it from one end to the other in a direction parallel to the longitudinal sides of the composite layers. The rolled-up blank thus has alternating layers of the first and second layers in radial cross-sections. The blank is then compressed in a press tool to the desired Tampongestalt -62- of Figure 8. The tampon is provided with the usual pull-out thread -68- which may be sewn to the distal end of the tampon or may be attached by other means known to those skilled in the art, eg by wrapping around the rectangular structure according to the invention before curling or is bound.

Figures 9 and 10 show yet another embodiment of the invention in a tampon. A rectangular wood pulp filling -70- is placed on a cover layer -72- of porous, cellulose-containing nonwoven fabric and forms the first and third layers of the structure according to the invention. Over this filling -70- lies a layer 74 of an absorbent mixture of peat and ground mechanical wood pulp, which layer 74 is the second

Nr.387310

7 represents layer according to the invention. The filling -70- with the nonwoven cover sheet -72- is then folded along its center line in the longitudinal direction and then folded again to form a U-shaped blank as shown in Fig.9. The blank is then placed in a cylindrical die and compressed radially and / or longitudinally to the desired tampon shape -76- of FIG. At the distal end of the compressed tampon -76- there is a withdrawal thread -78- which can be attached in the same manner as described above, namely by stitching or by tying the thread before folding about -70 The finished tampon 76 then comprises mid-layers or layers of peat-containing absorbent material which layers are laid on layers of wood pulp. Because of the property of preferred containment having this structure, the outer layer -70- in use retains disproportionately less fluid than the inner layers -74- and, as a result, tends to become saturated as the last layer. In other words, this means that the tampon fills from the inside to the outside. Accordingly, fluid impinging on the outer surface of the tampon will always encounter unsaturated absorbent material so that the likelihood of fluid dripping out of the tampon is less.

The following examples illustrate the advantages of the invention. Unless otherwise stated, all percentages are by weight. In each of these examples, the absorbent material was treated to also contain a wetting agent in amounts less than 0.5% by weight, based on the dry absorbent material. As a wetting agent is a from the Fa. Rohm &amp; Haas Company under the designation Triton GR-5 used in the market containing sodium dioctylsulfosuccinate.

Example 1: According to the teachings of the invention, a series of samples are prepared. Each of these samples consists of several rectangular absorbent layers measuring 22.9 x 30.5 cm.

The first sample consists of a first and a second layer wherein the first layer weighs 18.5 grams and is made from 90% kraft wood pulp fibers and 10% rayon fibers. This mixture is stabilized with an acrylic resin latex emulsion as an adhesive binder and contains 5.7% of this binder, based on the weight of the binder-free fibers. The second layer weighs 15.5 g and consists of 35.0% bleached peat having a brightness of 70, measured on a Hunter Color Scale System C scale, 43.5% ground wood pulp with a CSF value of 80.8 , 5% long fiber Kraft wood pulp and 13.0% rayon fibers with a denier of 1.5 and a staple fiber length of 3.05 cm. The mixture is bonded with the same adhesive and with the same amount of adhesive as the first layer.

The second sample consists of a first and a second layer, wherein the second layer weighs 9 g and is otherwise identical to the second layer described above in connection with the first sample. The first layer is made from 9.0 g of air-laid Kraft wood pulp.

The third sample consists of three layers, the first layer being made of 12.5 grams of air-laid Kraft wood pulp and the second layer made of 14.5 grams of the same peat-containing material described above in connection with the first sample and the third layer consists of a single ply of paper wadding, weight 2.5 g.

These samples are assayed as follows to determine their ability to retain liquid preferentially. Each sample is placed on a flat surface with the first layer facing up. Then be 30 cm³ of a 1% by weight sodium chloride solution was applied to the middle of the first layer of each sample. The liquid is allowed to diffuse through the sample for 20 minutes. Then, from the middle part of the sample, u.zw. where the fluid had been applied, punch out a 7.5 cm diameter disc and measure the amount of fluid retained per unit weight of each layer in each sample. The results are shown in Table 1 below.

From Table 1 it can be seen that when laying the layers of the samples prepared according to the teachings of the invention the original, preferred fluid distribution according to the invention is achieved. In particular, it can be seen that 2.2 to 3.13 times as much fluid is retained in the peat layer as in the next best fluid retaining layer.

Example 2: A series of sanitary napkins having the construction shown in Figs. The bandages have a total length or total width of 24.7 or 6.0 cm. The bandages have a cover layer of nonwoven fabric, u.zw. a bonded nonwoven fabric consisting of 100% rayon fibers and a basis weight of 20.33 g / m² Has. To simplify the design, the samples are provided with a single layer of tissue paper between the 0.0125 mm thick polyethylene barrier film and the nonwoven cover layer. Each of the bandages is equipped with an absorbent element composed of several layers and in each sample the uppermost layer of the element (dl the layer which is closest to the side in contact with the body) and the lowest layer of the element (ie the layer closest to the side in contact with the washing), each consisting of 4 g of air-laid, fluffy bleached Kraft wood pulp comprising 90% by weight softwood pulp and 10% by weight hardwood pulp. The middle layer of the absorbent member is made of the following materials in each sample, with the peat and the ground wood pulp being of the same kind as in Example 1.

Control Samples: A layer of high-bulk cotton, consisting of three layers of creped

Tissue paper is folded four times, resulting in a total of 12 layers weighing 1.55 g.

Samples A and B: a second layer (from above) of high bulk cotton of the same type as the batting of the second layer of control samples, and a third layer consisting of:

35.0% peat, 43.5% ground wood pulp, 8.5% long-fiber Kraft wood pulp and 13.1% rayon fiber;

Sample C: a middle layer consisting of a laminate structure comprising a top layer of wood pulp, a middle layer of a mixture of 40% peat, 50% ground wood pulp and 10% kraft pulp, and a bottom layer of wood pulp; the laminate weighs 4 g and is bound continuously with 5% of an adhesive per g of glue-free material;

Sample D: a middle layer consisting of 1.55 g of a mixture comprising:

% By weight of peat, 50% by weight of ground wood pulp and 10% by weight of Kraft wood pulp; the layer is bonded with about 4% by weight adhesive;

- 9 - Nr.387310

Sample E: a middle layer consisting of a laminate whose topmost layer has the same composition as the middle layer of the sample D and whose bottom layer consists of wood pulp. Both layers are bonded with about 4 wt .-% adhesive and each have a weight of 1.2 g.

The samples are all tested by placing spare menstrual fluid at the top of the pads at a speed of 3.1 cm³/ h for 2 h and thereby a total liquid absorption of 6.2 cm³ creates. The samples are then weighed again to determine the distribution of the retained fluid. These results are in the following

From these results it can be seen that the middle layer of the control samples did not absorb more than 1.6 or 1.7 times as much fluid as the next best-retaining layer. In contrast, the peat-containing layer of the inventively constructed samples held back 2.2 to 5.8 times as much fluid as the next best-retaining layer. In addition, unlike the control samples, the next most conservative layer was the topmost layer. It was found that the lowest layer of the inventively constructed samples retained only a very small percentage of the total amount of absorbed fluid at most.

Example 3: A series of samples of sanitary napkins of the general construction shown in Figures 3 and 4 are made. In any case, the bandages have a total length of 19.7 cm and a total width of 5.7 em. The porous cover layer is a nonwoven fabric consisting of 100% rayon fibers. The barrier film used is a 0.0125 mm thick polyethylene film. The C-folded material consists of about 2.45 g of a mixture of 85% wood pulp and 15% rayon bonded with 1.5% by weight of an adhesive. For the control samples, the absorbent layer sandwiched between the C-fold consists of three layers consisting of a blend of 85% wood pulp and 15% rayon bonded with 1.5% adhesive, the absorbent layer having a total weight of 3, 7 g has. Samples prepared according to the invention were provided with an inlaid layer consisting of a mixture of 35.2% by weight of peat, 44% by weight of ground wood pulp, 8.8% long-fiber Kraft wood pulp and 12% rayon , 5% by weight of adhesive is bound. The samples were examined in vitro, u.zw. using replacement menstrual fluid containing fluid for 3 hours at a rate of 3 cm³/ h and in a total of 9 cm³ each bandage has been applied to this.

The pads were then weighed to determine the distribution of the amount of fluid retained in each layer. The results are shown in Table 3 below:

Table 3

<td>sample</td><td>% Fluid in the C-fold</td><td>% Fluid in the inlaid layer</td>

<td>control sample</td><td>37.0</td><td>59</td>

<td>Peat-containing inserted layer</td><td>20.0</td><td>79</td>

As can be seen, the center liner has retained only 1.6 times as much fluid as the C-fold, while the sample constructed in accordance with the invention retained nearly 4 times as much as this.

Samples of the above construction are tested in vivo by menstruating individuals, users 1 and 2. Each user wore both the control sample and the peat deposit samples during the active part of their daily routine. The pads are returned. The distribution of the menstrual fluid retained in each of the components is measured and is shown in Table 4 below:
