Definitions

  • the present invention relates to absorbent articles with a reduced carbon footprint, and methods for making such articles.
  • Cradle-to-grave is the full Life Cycle Assessment from extraction of raw material ('cradle') to use phase and disposal phase ('grave').
  • Cradle-to- gate is an assessment of a partial product life cycle from extraction of raw material ('cradle') to the factory gate.
  • the term "gate" can apply to a number of points in a manufacturing process - e.g. finished material at the material producers' gate, or finished products at the gate of a further manufacturing process. Using these tools, efforts can be made to reduce the amount of atmospheric C0 2 emitted during a process, and to even adapt the process so that the overall result is a reduction in the amount of atmospheric co 2 .
  • Carbon dioxide from the atmosphere is converted into carbon-containing compounds during photosynthesis. Plants are therefore considered able to "lock" atmospheric carbon dioxide into their structure during their growth. However, subsequent decomposition of the plant matter - or incineration thereof - releases the locked-in carbon as carbon dioxide again.
  • Absorbent products such as diapers typically comprise plant material (typically pulp fluff and cellulosic materials) where the carbon in these materials has originated from atmospheric C0 2 . Upon disposal in landfill sites, or upon incineration, absorbent products decompose, and atmospheric C0 2 is released again.
  • WO 1996/009248 describes the use of atmospheric C0 2 as a source for papermaking fillers.
  • the present invention thus provides an absorbent article such as e.g. a diaper, a sanitary napkin, a panty liner or a male or female incontinence article.
  • the article comprises inorganic material.
  • the inorganic material comprises carbon which is derived from atmospheric carbon dioxide (C0 2 ).
  • the inorganic material comprising carbon suitably has a 14 C/ 12 C ratio of 1 x 10 "13 or greater, preferably 3 x 10 "13 or greater, more preferably 5 x 10 "13 or greater.
  • the inorganic material is suitably a carbonate salt, e.g. a carbonate salt of an alkali metal (Group 1 ), alkaline earth metal (Group 2) and mixtures thereof.
  • the inorganic material may be calcium carbonate.
  • the absorbent article may comprise a plastic film, and the inorganic material may be located within the plastic film.
  • the absorbent article may comprise synthetic fibres, said inorganic material being located within the synthetic fibres.
  • the invention also provides a method for making an absorbent article, said method comprising the steps of:
  • the method may include the additional steps of:
  • the metal carbonate of the above method is suitably calcium carbonate.
  • inorganic is meant a material which is not of plant or animal origin, and does not comprise organic materials such as cellulose, or fossil fuels such as oil etc. Inorganic materials are typically salts. Examples of inorganic materials include metal carbonates, cyanides, cyanates, carbides and thiocyanates.
  • An absorbent article is an article intended to be worn in the crotch region of a wearer, and which is used for the uptake and management of bodily exudate: e.g. blood, urine, feces etc.
  • the article is worn closest to the skin, under the clothing of the wearer.
  • absorbent articles are articles such as diapers, sanitary napkins, panty liners or male or female incontinence articles.
  • Carbon dioxide (C0 2 ) occurs naturally in the atmosphere in trace amount (less than 0.05%).
  • “Atmospheric” carbon dioxide is used to mean carbon dioxide in gaseous form which comes directly from the earth's atmosphere. Additionally, “atmospheric" carbon dioxide can refer to carbon dioxide which is a waste product of industrial processes, e.g. obtained from the waste flues of other processes and recycled.
  • Figure 1 illustrates an absorbent article according to the invention, being a diaper.
  • Figure 2 is a cross-sectional view along the line ll-ll in Figure 1.
  • FIG. 1 shows an absorbent article 10 according to the invention, in the form of a diaper.
  • the invention is described with reference to a diaper, it is equally relevant to other absorbent articles, such as e.g. sanitary napkins, panty liners or male or female incontinence articles.
  • the term "absorbent article” refers to products that are worn against the skin of the wearer to absorb and contain body exudates, like urine, faeces and menstrual fluid.
  • the present invention mainly relates to disposable absorbent articles, which means articles that are not intended to be laundered or otherwise restored or reused as an absorbent article after use.
  • the absorbent article 10 typically comprises a liquid-pervious topsheet 1 1 which lies closest to the wearer when the article 10 is being worn.
  • An absorbent body 12 typically lies under the topsheet 1 1.
  • a liquid- impervious backsheet 13 is usually located between the absorbent core 12 and the wearer's garments.
  • absorbent articles 10 comprise all three of these components; however, certain absorbent articles 10 may lack one of these components.
  • the liquid-pervious topsheet 1 1 lies closest to the wearer's skin, and makes contact therewith. It also allows bodily exudate to pass through to the underlying absorbent body 12.
  • the materials suited as topsheet 1 1 should therefore be soft and non-irritating to the skin and intended to be readily penetrated by body fluid, e.g. urine or menstrual fluid.
  • the topsheet 1 1 can consist of a nonwoven material, e g spunbond, meltblown, carded, hydroentangled, wetlaid etc. Suitable nonwoven materials can be composed of natural fibers, such as woodpulp or cotton fibres, manmade fibres, such as polyester, polyethylene, polypropylene, viscose etc. or from a mixture of natural and manmade fibres.
  • topsheet 1 1 may comprise a plastic film, which is perforated to allow the passage of liquid.
  • the topsheet 1 1 may further be composed of tow fibres, which may be bonded to each other in a bonding pattern, as e.g. disclosed in EP-A-1 035 818. Further examples of materials suitable for topsheet 1 1 are porous foams, apertured plastic fiims etc.
  • the topsheet 1 1 may be different in different parts of the absorbent article.
  • the liquid-impervious backsheet 13 lies on the garment-facing surface of the absorbent body 12 and acts to prevent bodily exudate from leaking from the absorbent body 12 and staining the wearer ' s garments.
  • the liquid-impervious backsheet 13 covering the absorbent body 12 on the garment-facing side is therefore of a liquid impervious material, such as a thin plastic film, e.g. a polyethylene or polypropylene film, a nonwoven material coated with a liquid impervious material, a hydrophobic nonwoven material which resists liquid penetration or a laminate of one or more plastic films with one or more nonwoven materials.
  • the liquid-impervious backsheet 13 preferably comprises a soft nonwoven material on the garment-facing surface thereof.
  • the liquid-impervious backsheet 13 could be breathable so as to allow vapour to escape from the absorbent body 12, while still preventing liquids from passing therethrough.
  • breathable liquid-impervious backsheets 13 are porous polymeric films, nonwoven laminates from spunbond and meltblown layers, laminates from porous polymeric films and nonwovens.
  • the absorbent body 12 acts to accept and retain bodily exudate from the wearer. It therefore comprises absorbent material.
  • the absorbent body 12 can be of any conventional kind. Examples of commonly occurring absorbent materials are cellulosic fluff pulp, tissue layers, highly absorbent polymers (so called superabsorbents), absorbent foam materials, absorbent nonwoven materials or the like. It is common to combine cellulosic fluff pulp with superabsorbents in an absorbent body 12.
  • the thin absorbent bodies which are common in for example baby diapers and incontinence guards, often comprise a compressed mixed or layered structure of cellulosic fluff pulp and superabsorbent.
  • the size and absorbent capacity of the absorbent body 12 may be varied to be suited for different uses such as for infants or for incontinent adults.
  • the absorbent body 12 may comprise one or more layers which may be selected to improve the handling of bodily waste. Such layers are designed to receive a large amount of liquid in a short space of time and distribute it evenly across the absorbent body 12. They may include so-called transfer, distribution, surge or acquisition layers, and are usually located between the topsheet 1 1 and the absorbent body 12 and/or between the absorbent body 12 and the backsheet 13.
  • the topsheet 1 1 and backsheet 13 generally have a similar extension in the X-Y plane, while the absorbent body 12 usually has an extension which is somewhat smaller.
  • the topsheet 1 1 and backsheet 13 are joined to one another around the periphery of the absorbent body 12, so that the absorbent body 12 is enclosed within the envelope formed by the topsheet 1 1 and the backsheet 13.
  • the absorbent body 12 is at least located in the crotch portion of the absorbent article 10, and may also extend somewhat into the front and rear portions.
  • the topsheet 1 1 , absorbent body 12 and backsheet 13 may be joined to one another by any means common in the art, e.g. ultrasonic welding, thermal welding or gluing.
  • the absorbent article 10 comprises inorganic material.
  • the inorganic material may have various functions; e.g. to absorb liquid or odours, to provide bulk to the absorbent article and the materials thereof, or to provide breathability in that the inorganic material facilitates the formation of a porous structure.
  • the inorganic material comprises carbon. Most suitably, the carbon is present as a carbonate anion (C0 3 2 ).
  • Other inorganic materials comprising carbon include e.g. cyanides (CN ), cyanates (OCN ), carbides, thiocyanates (SCN ).
  • the inorganic material is a salt - i.e. a material consisting of cations and anions in a suitable ratio so that the overall charge is zero.
  • the inorganic material may consist of carbonate salts, e.g. the carbonate salts of alkali metals (Group 1 : e.g. Li, Na, K) and alkaline earth metals (Group 2: e.g. Mg, Ca) and mixtures thereof.
  • the inorganic material is calcium carbonate (CaC0 3 ).
  • the carbon in the inorganic material is derived from atmospheric carbon dioxide (C0 2 ).
  • the inorganic material is derived from atmospheric carbon dioxide (C0 2 ) within the preceding 20 years, preferably within the preceding 10 years.
  • carbon in the inorganic material is derived from atmospheric carbon dioxide, carbon dioxide is removed from the atmosphere during the manufacture of the inorganic material, and thus, the manufacture of the absorbent articles 10.
  • the absorbent articles 10 of the invention can be distinguished from known absorbent articles by analysing the ratio of carbon isotopes in the inorganic material (in a process similar to "carbon-dating").
  • the isotope of interest is 14 C, which is often created in the upper layers of the earth's atmosphere. 14 C decays radioactively. As 14 C is constantly being generated in the atmosphere, the ratio of ,4 C to 12 C in the atmosphere is relatively constant. However, when 14 C is trapped in rocks or minerals, or fossil fuels such as oil, the amount of 14 C gradually falls.
  • the invention thus provides an absorbent article, in which the inorganic material comprising carbon has a 1 C/ 12 C ratio of 1 x 10 "13 or greater, preferably 3 x 10 "13 or greater, more preferably 5 x 10 "13 or greater. Further details of the 1 C/ 2 C ratio, and suitable methods for its determination are discussed in US2007/0219521 and references cited therein.
  • the inorganic material is calcium carbonate
  • a suitable method for the manufacture of this material from atmospheric C0 2 may be found in W01996/009248.
  • the reaction formula to make this CaC0 3 is CaS0 4 + H 2 0 + C0 2 (atm) - CaC0 3 + H 2 S0 4
  • the inorganic material of the invention may be located in one or more components of the absorbent article 10 set out above. That is, it may be located in the topsheet 1 1 , the absorbent body 12 or the backsheet 13, or more than one of these components.
  • the inorganic material is usually present in particulate form.
  • the inorganic material of the invention may be located within a plastic film. Suitable polymers for making the plastic films include polyalkenes (e.g.
  • the polymer may come from a renewable source (so-called bio-polymers).
  • bio-polymers would have a further positive effect on the calculation of C0 2 equivalents emitted during the disposal or incineration of the materials and products of the invention.
  • Plastic films comprising inorganic material are known in the art, e.g. US6576809, JP2000136254 . Such films are typically manufactured by adding the inorganic material to the molten polymer, prior to stretching or blowing the polymer into a film. The inorganic material in such films provides porosity to the film.
  • the inorganic material may be present in 30-70 weight % in the films of the prior art. According to the invention, the inorganic material may be present in the plastic film in 2-80 weight %, preferably 5-70 weight %. If the inorganic material is located within a plastic film, this plastic film may be present in the topsheet 1 1 or the backsheet 13 of the article 10, preferably the backsheet 13.
  • the invention therefore provides an absorbent article 10, wherein the absorbent article 10 comprises a plastic film, said inorganic material being located within the plastic film. Even more preferably, the backsheet 13 of the absorbent article 10 of the invention comprises a laminate, in which the plastic film of the invention is one of the layers.
  • the inorganic material of the invention may be located within synthetic fibres.
  • Suitable polymers for making the synthetic fibres include polyalkenes (e.g. polyethylene, polypropylene, or mixtures thereof), polyesters and polyamides, or mixtures thereof.
  • the polymer of the synthetic fibres may come from a renewable source (so-called bio-polymers).
  • the fibres may be monocomponent, bicomponent or multicomponent fibres.
  • the fibres may be continuous fibres or staple fibres.
  • Synthetic fibres comprising inorganic material are known in the art, e.g. US 20090104831 , US 4341213. The inorganic material in such fibres provides porosity and other properties to the fibres.
  • Inorganic material may be added to the polymer from which the fibres are made, prior to the fibres being drawn or blown. Inorganic material may be present in the synthetic fibres of the invention in 2 - 40 weight %, preferably 5 - 25 weight %.
  • the synthetic fibres comprising the inorganic material of the invention may be formed into a nonwoven layer (e.g. as part of the topsheet 1 1 , backsheet 13 or another layer), or may be loosely arranged as part of the absorbent body 12.

  • the metal carbonate used in the above methods may be calcium carbonate.
  • Plastic film or synthetic fibres may be incorporated into any suitable component of the absorbent article 10.
  • the plastic film may be incorporated into the backsheet 13 of the absorbent article 10.
  • 1 mole C0 2 gives 1 mole CaC0 3 .
  • the molecular weight is 80g/mole for CaC0 3 and 44 g/mole for C0 2 .
  • CaS0 4 is a waste product from other industrial processes, no C0 2 contribution from producing this material is added. Comparisons are made with CaC0 3 which is mined from the ground. The mining process has itself a certain carbon footprint.
  • Example 1 polymer granules
  • C0 2 equivalents were estimated for the production of polymer granules.
  • the "gate" in this example is considered as the production of finished polymer granules.
  • the conversion of the polymer granules to films and fibres, and product manufacture can give different C0 2 equivalents depending on how efficient the converting lines are and the energy source used for production. Both the extrusion to film and spinning to fibres to production of NW are very dependent on the production unit, the technology and the energy source (which differ from country to country). In nonwoven production, energy consumption gives a C0 2 contribution of 0.7-1.4.
