Definitions
- This invention relates to absorbent materials and to their manufacture.
- the invention relates to absorbent materials comprising a laminate of two or more layers of fibres having absorbent material between the layers of fibres.
- the invention relates to materials suitable for use in diaper manufacture.
- Diapers manufacturers have been looking for ways of using super absorbent polymers (SAP) in diaper products based on their performance to cost ratio and the reduction, in thickness of the products. The problem has been how to get the SAP powder/granules into a stable product so that liquid is absorbed effectively.
- SAP super absorbent polymers
- Laminated products comprising two webs bonded together with SAP therebetween can allow expansion if there are spaces between points of lamination but in these cases the SAP is free to migrate during processing or before getting wet giving uneven loading and reduced performance i.e. the SAP moves to places that do not get wet or it collects in lumps which are less effective at absorbing than when in thin layers due to a reduction in surface area in contact with the liquid.
- Our co-pending British Patent Application No. 9318971.0 discloses a liquid sorbent article comprising at least one layer of sorbent fibrous material and at least one hinge about which the article may be preferentially folded, the hinge being formed by permanently bonding the fibres of the layer under pressure along a line.
- sorbent sheet material with hinges formed by bonding fibres under pressure the strength characteristics of the article is improved and the use of the article in a variety of formats is facilitated.
- suitable positioning of the hinges allows the article to be fan-folded for packaging and in use the article can be used in the form of a sheet, mini- pillow or boom by simple folding to increase the thickness of the article.
- the hinges enable the sheet material to adopt and maintain a folded configuration without the need for intermittent releasable bonds.
- the hinges are formed by welding the fibres under pressure, more preferably by pressure welding without application of heat.
- the article is preferably constructed of at least two contiguous layers of sorbent material which are bonded together by a plurality of hinges and optionally at one or more edges. Such a two layer product has improved strength over a single layer article of the same basis weight.
- the hinges are generally formed as a straight line extending across or along the length of the article.
- the hinges may be continuous or discontinuous, providing the article may be preferentially folded along the line.
- the hinge may be formed with perforations along the line to facilitate tearing the sheet into desired sizes.
- the articles comprise a plurality of parallel hinges.
- welds need not be formed in a straight line and may adopt other configurations, e.g., sinusoidal or zig-zag paths. Such configurations are particularly suitable for use with multilayered articles since it allows contiguous layers to be bonded in a similar manner to quilting. Furthermore, by suitable positioning of the welds it is possible to form a series of pockets between two contiguous layers which can be filled with particles, e.g., absorbents, indicators, neutralizers, etc. The pockets prevent the particles from moving freely about the material. Such particles may be dropped onto the lower web prior to application of the upper web and pressure welding.
- the blunt slitters used for pressure welding may have working edges adopting the desired sinusoidal or zig-zag configuration and are conveniently arranged such that the re-entrant portions of adjacent welds are adjacent thereby dividing the web into substantially discrete islands.
- EP 0146190 discloses an absorbent article comprising a layered absorbent structure having an upper surface and a lower surface, and comprising: (a) n webs of fibrous materials, n being an integer of two or more, said webs being layered such that there is an uppermost web, a lowermost web, n-2 intermediate webs, and n-1 interfaces of two opposed adjacent contacting surfaces of adjacent webs, each of the interfaces having a surface area; and (b) absorbent particles forming a discontinuous layer at one or more of the interfaces; the opposed adjacent contacting surfaces at each of the interfaces where the particles are present being substantially entirely frangibly bonded by fibre entanglement between the contacting surfaces, the particles being immobilized at the interface(s) substantially entirely by fibre entrapment.
- the particles are immobilized but free to absorb fluid as if they were unconstrained since the bonds between the contacting webs near a swelling particle will be easily broken allowing the particle to freely swell.
- an absorbent- article comprising two contiguous layers of fibre webs having therebetween particles of absorbent material, the layers being laminated together by a combination of permanent bonds and semi-permanent bonds which are positioned to define spaces which contain particles of the absorbent material, the semi-permanent bonds being releasable upon expansion of the absorbent material as it absorbs liquid, the permanent bonds ensuring dimensional stability of the article before and after absorption of liquid.
- the absorbent articles of the invention provide a simple, effective arrangement for incorporation of particles of absorbent material within a laminated structure. A series of spaces or pockets is defined by the laminating bonds in which the particles are contained thereby restricting undue movement of the particles without having to immobilize individual particles.
- a portion of the laminating bonds are semi-permanent or releasable which break or release as the particles of absorbent swell thereby allowing the particles to retain maximum absorbing capacity.
- the invention does not require fibre entanglement to form the releasable bonds.
- the permanent bonds are positioned at least at the sides and/or ends of the article, more preferably completely around the periphery.
- the article may comprise other permanent bonds spaced across the layers, e.g., one or more lines of bonds.
- the permanent bonds may conveniently be formed by welding the layers, e.g., by heat, pressure, ultrasonics or any combination thereof. The result of the welding is that the fibres are completely fused together at the bond, the identity of individual fibres not being discernible in the bond.
- both the permanent and semi-permanent welds are formed by cold pressure welding using blunt slitters, the blunt slitters having working edges having a sinusoidal or zig-zag configuration.
- the articles of the present invention can be formed from a wide range of sorbent sheet materials which can be laminated. Such sheet material include, for example nonwoven, fibre webs such as microfibrous sheet material, and wood pulp based webs which are well known to those skilled in the art.
- the article generally has a basis weight of from 20 to 500g/m 2 .
- the articles of the present invention are preferably formed from at least one layer of sorbent microfibrous sheet materials, particularly melt blown microfibrous materials.
- sorbent microfibrous sheet materials particularly melt blown microfibrous materials.
- Such materials are described, for example, in van Wente "Superfine Thermoplastic Fibres", Industrial Engineering Chemistry, vol. 48, pp. 1342 et seq. (1956), or in Report No. 4364, Naval Research Laboratories, May 25, 1954, "Manufacture of Superfine Organic Fibres" by van Wente, A. Boone, CD., and Fluharty, E.L.
- the articles of the present invention are formed from at least one layer of melt blown microfibrous materials containing a surfactant topically applied or incorporated by direct addition of the surfactant to the molten polymer stream. Sorbent articles based on these __ , _,___ 95/21596
- Articles of the present invention which are formed from melt blown microfibrous materials typically have sufficient strength, even when saturated with liquid, that an outer facing is not required to maintain 0 integrity.
- An optional outer facing may, however, be provided by applying a scrim material, for example, to the microfibrous sheet materials prior to lamination to improve the appearance of the article and coincidentally produce a more durable article. This can be accomplished by collecting the melt blown microfibrous web material directly on the facing or 5 alternatively bonding the facing to the microfibrous material by using an intermittent adhesive pattern or pin laminating the materials together.
- Facing material can also be applied to the microfibrous sheet material as a coating, for example, latex, at a level which does not substantially affect the sorbency of the microfibrous sheet material.
- the product can be incorporated directly into standard wood pulp filled diaper lines without large redesign of the lines because it is strong enough to be unwound and pulled through the lines without breaking.
- product may be supplied in long lengths, with the diaper manufacturer cutting the product to length (typically 44cm) and making the end welds.
- hydrophobic bottom web gives soft feel, bulk and strength to the product, whilst preventing the penetration of liquid through 5 to the outside of the diaper.
- heat or ultrasonic welding may be employed or combinations of these methods.
