Definitions
- the present invention refers to a method of producing a fiber or group of fibers having a coating of at least two, preferably at least three, outside each other located thin layers of interacting polymers, at which the fiber or group of fibers is treated in consecutive steps with solutions of the interacting polymers.
- a coating modifies the properties of the fibers as well as the properties of the products, e g paper and nonwoven, in which the treated fibers are contained.
- Dual surface treatment of filler particles with anionic and cationic polymers is disclosed in EP-A-0 850 879, WO 95/32335, US-A-4,495,245 and US-A-4,925,530. There is no indication that the treatment takes place under such controlled conditions that a double- or multilayer is created on the pulp fibers with the anionic component in one layer and the cationic component in the other layer.
- the object of the present invention is to provide a method for producing fibers or groups of fibers, having a coating of at least two, preferably at least three, outside each other located thin layers of interacting polymers, at which the fiber or group of fibers is treated in consecutive steps with solutions of the interacting polymers. This has been provided by the fact that excess of the previous polymer is removed between each treatment step alternatively that the respective polymer is added only in such an amount in each step that substantially all polymer is adsorbed to the fiber surface.
- the fibers or groups of fibers may be of optional type, however e g cellulosic fibers, regenerated fibers and different types of synthetic fibers are mainly concerned.
- the interacting polymers are preferably alternating cationic and anionic polyelectrolytes, but they may also be so called zwitter ions.
- each of said thin layers is preferably between 3 and 100 ⁇ , more preferably between 7 and 20 ⁇ .
- the invention further refers to a paper- or nonwoven product, which contains fibers produced by the method described above.
- fibers or groups of fibers are treated with interacting polymers in order to build up thin multilayers of the interacting polymers on the fiber surface.
- interacting polymers in principle the technique described in for example above mentioned articles from Thin Solid Films is used in case alternating cationic and anionic polyelectrolytes are used as interacting polymers, with the difference that according to the invention the substrate is fibers groups of fibers.
- the fibers are treated in consecutive steps with solutions of the interacting polymers, at which the treatment time for each step is sufficient for forming a layer of the desired molecular thickness, preferably of the magnitude 5-100 ⁇ .
- the interaction between the fibers can be in the form of electrostatic forces, at which the polymers consist of alternating cationic and anionic polyelectrolytes, or by interaction between nonionic polymers by means of e g dispersion forces or hydrogen bonds. Examples of this type of interaction between nonionic polymers are adsorption of polyethylene oxide on unbleached cellulosic fibers and complex formation between polyethylene oxide and polyacrylic acid.
- the first layer should be a cationic polymer for particles or groups of particles having an anionic surface, which for example is the case for cellulosic fibers, and vice versa.
- Possible excess of the previous polyelectrolyte can be removed between every treatment step, e g by rinsing with water.
- the addition is controlled in such a way that no excess amount of the respective polymer is added in each step, so that substantially all polymer is adsorbed to the fiber surface.
- the method is based on electrostatic attraction between oppositely charged polyelectrolytes for building the desired multilayers.
- a solution containing polyions of opposite charge and pennit these spontaneously to adsorb to the particle surface multilayers of the stated kind are built up.
- all types of polyelectrolytes may be used.
- ion-exchanging fibers where "membranes" with ion-exchanging properties are provided on the fiber surface, wet strength agents where the added polymers are reactive with the fibers and with each other, in order to provide permanent bonds between the fibers and for the production of highly swelling surface layers, where the added chemicals form swollen gel structures on the fiber surface for use in absorbent hygiene products.
- Another possible application are new types of fibers for printing paper, where the adsorbed polymers change colour when they are exerted to an electric, magnetic or electromagnetic field. Such polymers are available today.
- the fibers that are treated with the method according to the invention can be of optional kind, natural as well as synthetic fibers. Mainly cellulosic fiber are concerned. However it would be possible to treat synthetic fibers, for example for giving them a more hydrophilic surface.
- groups of fibers can be treated according to the method.
- Anionic polyelectrolytes Anionic starch with different degrees of substitution, polystyrene sulphonate, carboxy methyl cellulose with different degrees of substitution, anionic galactoglucomannan, polyphosphoric acid, polymethacrylic acid, polyvinyl sulphate, alginate, copolymers of acryl amide and acrylic acid or 2-acrylic amide-2-alkylpropane sulphonic acid.
- Cationic polyelectrolyte Cationic galactoglucomannan, polyvinyl amine, polyvinyl pyridine and its N-alkyl derivatives, polyvinyl pyrrolidone, chitosan, alginate, modified polyacryl amides, polydiallyl dialkyl, cationic amide amines, condensation products between dicyane diamides, formaldehyde and an ammonium salt, reaction products between epichlorhydrine, polyepichlorhydrine and ammonia, primary and secondary amines, polymers formed by reaction between ditertiary amines or secondary amines or dihaloalkanes, polyethylene imines and polymers formed by polymerisation ofN-(dialkylaminoalkyl)acrylic amide monomers.
- the example below shows the increase of tensile strength of sheets made in a dynamic sheet former.
- the pulp that is used was bleached SWK (softwood sulphate pulp) beaten in accordance with SCAN-C 18:65, diluted to 3g/l and pH adjusted to 8.
- PVAm polyvinyl amine
- CMC carboxy methyl cellulose
- an anionic polymer was added in excess, and after 10 minutes non-adsorbed polymer was removed through washing. Admixture of PVAm and CMC was repeated in several steps.
- A-PAM anionic polyacryl amide
- DMDAAC canonic polydimethyl diallyl ammonium chloride
