Definitions
- the present invention relates to composite products and materials, used in particular as wiping articles, having improved absorbent qualities. It also relates to a process and a device for the preparation of these products or wiping articles, as well as their uses, in particular for the industrial wiping of various liquids (water, oil, greases, biological fluids, mixtures, etc.)
- the disposable wiping articles currently available are essentially composed of one or more thicknesses of sheets (or veils) of fibrous material, of the cellulose or viscose type, for example.
- these articles may contain from 1 to 5 sheets, linked together mechanically and / or chemically.
- the absorbency of these items is largely determined by the number of sheets. If these articles are suitable for domestic uses (handkerchiefs, paper towels, toilet paper, etc.) they are not, however, sufficiently suitable for industrial wiping, i.e. large areas, or large volumes of liquids, due to their limited absorbency.
- the wiping products made of non-woven fibers may have better absorbency and greater mechanical resistance, their cost is high, which limits their applications.
- a first object of the invention lies more precisely in an absorbent composite material, characterized in that it is composed of a superabsorbent product placed between two or more veils based on cellulose wadding, preferably bonded together by a full width mechanical embossing.
- a wiping article characterized in that it comprises, between at least two veils based on cellulose wadding, a super-absorbent product, preferably in pulverulent form, said veils preferably being linked together by a full width mechanical embossing.
- the products of the invention may be in the form of a roll, of a size suitable for the end use, or in the form of individual products, folded, tangled or not.
- another object of the invention relates to a roll of absorbent paper, comprising a strip of paper composed of two webs based on cellulose wadding enclosing a super-absorbent product, said strip comprising perforations allowing them to be torn according to a line, said webs being preferably linked together by a full width mechanical embossing.
- Another object of the invention resides in a process for preparing a wiping article or an absorbent composite material, comprising depositing, preferably uniformly, between at least two webs based on cellulose wadding. , of super-absorbent product, preferably in powder form.
- the invention also relates to a device for implementing the method, comprising (i) at least two cylinders making it possible to assemble the two webs and (ii) a means for depositing the super-absorbent, preferably in a uniform manner.
- Other aspects of the invention lie in the uses of materials and articles, in particular for industrial wiping or in methods for increasing the absorbency of cellulose wadding, as will be explained in the following text.

- the present invention now describes composite materials and absorbent wiping articles comprising, between at least two webs based on cellulose wadding, a super-absorbent product.
- the term “super-absorbent product” means any compound capable of swelling (or of forming a gel) in the presence of a liquid, without however dissolving. Such compounds can be of natural or synthetic origin, such as in particular alginates, starches, acrylamide, carboxymethylcellulose, acrylate, alone or in mixtures, or their derivatives.
- the super-absorbent compound used in the present invention is preferably in the form of a powder. This packaging ensures better dispersion of the product, without significantly affecting the thickness or texture of the final composite product. It is understood that the super-absorbent product can also be used in the form of a particle or a granule, without deviating from the present application.
- Preferred examples of superabsorbent products usable in the context of the present invention are crosslinked acrylic acid polymers and crosslinked norbornene polymers. Such superabsorbents are commercially available.
- Super-absorbent products have already been used in certain absorbent products for personal hygiene (diapers, periodic towels, etc.). However, these are complex products, often using fibrous mattresses, generally in combination with synthetic materials. In addition, in these products of the prior art, the super-absorbent is generally deposited selectively, in well-defined regions of the composite, which imposes significant technical constraints in terms of production.
- the present invention now describes new absorbent products, intended more particularly for industrial wiping, essentially comprising one or more veils based on cellulose wadding, between which is deposited one (or more) super-absorbent products. To our knowledge, such materials have never been reported in the prior art.
- the wiping products or absorbent materials according to the invention can comprise several thicknesses of webs based on cellulose wadding, in particular from 2 to 5 webs.
- the products according to the invention are composed of two veils based on cellulose wadding.
- the use of two sails is simpler and more economical, on the industrial level, and the introduction of a super-absorbent product in this type of product allows, according to the present invention, to considerably increase the absorbent power ( 300% or more).
- a more particular object of the present invention resides in a wiping article or an absorbent composite material, characterized in that it comprises two veils based on cellulose wadding between which a super-absorbent product has been placed.
- the sails (or sheets or sheets) based on cellulose wadding used in the context of the present invention preferably consist mainly of cellulose wadding. Preferably, they comprise more than 60% of cellulose wadding, even more preferably more than 75% of cellulose wadding. In a particular mode, they consist entirely of cellulose wadding.
- Other agents or products can enter into the composition of the veils according to the invention, such as in particular agents making it possible to increase the resistance of the veils in the wet state.
- mention may be made in particular of the use resins for example synthetic resins (typically epichlorohydrin resin), which protect the fiber bonds of the sails and improve their resistance to the action of disintegration by water.
- Such agents or resins generally represent less than 1% by weight of the composition of the veil.
- the sails may contain other materials or fibers, used in the paper or textile industry.
- sails made from cellulose wadding can be made from virgin or recycled fibers.
- sails from 12 to 60 g / m 2 per sail can be used, more generally from 16 to 40 g / m 2 .
- the width and length of the sails can be adapted by a person skilled in the art depending on the intended use. It can in particular be strips wound on rolls or individual sheets.
- the amounts of super-absorbent used can also be adapted by a person skilled in the art according to the desired use, the super-absorbent used, the number of veils, etc.
- the products and articles according to the invention comprise from 1 to 15 g / m by weight of superabsorbent. More preferably, they comprise from 1 to 8 g / m by weight of super-absorbent and even more preferably from 4 to 6 g / m by weight of super-absorbent.
- the super absorbent can be held between the sails in different ways.
- the super-absorbent is maintained by mechanical embossing of the sails. It is preferably a full-width embossing, that is to say affecting the entire surface of the web, and not just certain strips of it (knurling).
- the super-absorbent is maintained by mechanical and chemical embossing of the sails.
- the chemical embossing includes in particular the use of adhesives, in particular biological and / or synthetic glues. By way of example, mention may be made of a starch-based adhesive.
- a particular embodiment comprises the full width embossing of the “nested” type, preferably in the presence of an adhesive: this type of embossing is illustrated in FIG. 1.
- Another embodiment is a point-to-point embossing, as shown in FIG. 2.
- a specific embodiment of the present invention therefore relates to a wiping article, comprising at least two webs based on cellulose wadding between which a super-absorbent pulverulent product has been placed, the webs being linked together mechanically by an embossing. full width, preferably of the “nested” type, even more preferably combined with a chemical binder.
- the wiping articles according to the invention are generally devoid of fibrous mattresses and / or other synthetic materials encountered in personal hygiene articles.
- the products and materials according to the invention can be prepared in different ways.
- One of the advantages of these products also lies in the ease of industrialization of the process, since machines or parts of machines combined, commonly used at the final stage of the manufacture of cellulose wadding (for a semi-worked product), or machines or parts of machines commonly used in the processing of cellulose wadding (for finished products) can be used.
- An object of the invention therefore also relates to a process for preparing a wiping article or an absorbent material as described above, comprising depositing, preferably uniformly, between at least two webs based cellulose wadding, super-absorbent product.
- the method of the invention comprises an additional step of bonding the webs, making it possible to maintain all or part of the super-absorbent product.
- Another object of the invention relates to a process for increasing the absorbency, for various liquids, of cellulose wadding, comprising depositing, preferably uniformly, between two or more webs based on cellulose wadding. super-absorbent powdery product (s).
- the superabsorbent product or products can be chosen according to the liquid to be absorbed, and their quantity is adapted according to the desired use.
- the deposition of the super-absorbent is carried out dry. It can in particular be carried out by spraying (using air or compressed gas) or by electrostatic deposition, spraying being a preferred mode.
- the spraying is for example carried out between the two webs, during their assembly, and the deposit made is maintained by embossing as indicated above, preferably by embossing binder of the “nested” type.
- embossing as indicated above, preferably by embossing binder of the “nested” type.
- This process advantageously allows the use of machines commonly used in the transformation of cellulose wadding, after installation in the machine of the means for spraying the super-absorbent.
- Spraying also allows uniform deposition of the superabsorbent, and control of the amount deposited can be obtained by changing the flow rate or pressure of the carrier gas.
- the superabsorbent product can be introduced either between each veil, or between some of them only, or even between two of them only.
- a preferred embodiment of the process of the invention comprises the dry deposition of a super-absorbent product presented in powder form between two or more sails made of cellulose wadding, and maintaining the product thus deposited by creating a mechanical connection between the sails, possibly reinforced by partial sizing.
- the invention further relates to a device for the production of absorbent composite materials as described above, comprising (i) at least two cylinders making it possible to assemble two webs based on cellulose wadding and (ii) means for deposit the super-absorbent, preferably evenly. These assembly and deposition means are arranged so as to maintain the super-absorbent product in the final composite material.
- the means for depositing the super-absorbent can be a (ramp of) spray nozzle (s), or cylinders for electrostatic deposition.
- at least one of the cylinders allowing the assembly is engraved to allow the realization of a mechanical embossing of the sails.
- FIG. 3 A specific embodiment of the invention is shown in Figure 3.
- at least two veils based on cellulose wadding are unwound from the rollers (A) and (B), thus creating a separation between the two sails.
- the superabsorbent pulverulent product is deposited or projected between these sails (on one of the sails, on both, or in the area of separation of the sails), using spray nozzles distributed over the width (C). .
- a mechanical connection is then made (by points) between the sails in order to keep all or part of the super-absorbent product in place.
- the latter can for example be housed in the cells left by the mechanical junction.
- the mechanical connection is preferably obtained by pressure passage of the webs between the two cylinders (D), at least one of the two being etched in order to obtain a local extension of the web, allowing a junction (generally by point).
- the junction can also be reinforced by pre-gluing the points obtained by embossing, by means of the cylinder (E).
- the product is either wound in coils of large dimensions in order to obtain a semi-finished product usable as raw material for a later stage of processing, or wound into coils directly usable by users (F).
- the composite product can also, using a suitable processing device, be cut into folded or unfolded sheets, presented in entangled form or not.
- the products and articles of the invention are particularly suitable for industrial wiping, in particular in medical centers (hospitals, morgue, laboratories, etc.), technical premises, garages, factories, warehouses, in various industrial fields where the absorption of liquid is essential (automobile, aeronautics, printing etc.), in the transport of fruits and vegetables.
- the advantages of the invention are numerous, and in particular the manufacture of inexpensive, highly absorbent composite products, which can be produced economically and industrially by means of conventional installations.
