Description
PAPIER COUCHE POSSEDANT UN TOUCHER SOYEUX
La présente invention se rapporte à une composition de couchage comprenant des microbilles de polyuréthane et au papier enduit sur au moins une face de ladite composition de couchage, et de manière avantageuse sur ses deux faces.
Des papiers de types ou de compositions diverses peuvent être couchés de façon à accroître la qualité de leur surface.
Une composition de couchage utilisée de manière conventionnelle dans ce but est une dispersion comprenant des pigments, lesquels peuvent être organiques ou minéraux.
La composition de couchage peut également comporter d'autres additifs.
Des papiers destinés à l'impression, tels que des papiers pour livres, magazines, brochures, ou rapports annuels, ou encore des papiers destinés à
l'emballage sont souvent fabriqués en enduisant un papier support à l'aide d'une ou plusieurs unités de couchage, suivis parfois d'un calandrage.
Le produit final doit en général posséder des caractéristiques de surface améliorées pour l'usage qui en est fait.
Ces caractéristiques de surface se traduisent pour l'essentiel par une modification de l'aspect visuel du papier soit par accroissement de sa blancheur, de sa brillance, ou encore de son opacité.
La recherche d'un certain toucher de surface pour la feuille recouverte de la couche est en soi assez nouveau.
Dans le brevet antérieur FR 2791368, la Demanderesse s'était intéressée à
fournir une feuille d'emballage qui comporterait une caractéristique qui rappellerait l'une des caractéristiques essentielles du produit à emballer, en particulier pour les produits cosmétiques à appliquer sur la peau.
La Demanderesse proposait donc de fournir une caractéristique qui évoque la destination, à savoir la peau, c'est-à-dire le toucher, la douceur de la peau.
Le toucher recherché pouvait être obtenu en appliquant à la surface de la feuille une couche qui comportait des microsphères thermoplastiques expansibles. LAYER PAPER HAVING A SOFT TOUCH
The present invention relates to a coating composition comprising polyurethane and paper-coated microbeads on at least one side of said coating composition, and advantageously on both sides.
Papers of various types or compositions can be coated way to increase the quality of their surface.
A coating composition conventionally used for this purpose is a dispersion comprising pigments, which may be organic or minerals.
The coating composition may also include other additives.
Papers intended for printing, such as book papers, magazines, brochures, or annual reports, or papers intended for packaging are often made by coating a paper backing using one or several sleeping units, sometimes followed by calendering.
The final product must generally have surface characteristics improved for the use made of it.
These surface features are essentially reflected in a modification of the visual appearance of the paper, either by increasing its whiteness, of its brilliance, or its opacity.
The search for a certain surface touch for the sheet covered with layer is in itself quite new.
In the previous patent FR 2791368, the Applicant was interested in provide a packing sheet that would include a feature that recall one of the essential characteristics of the product to be packaged, in particular for the cosmetic products to apply on the skin.
The Applicant therefore proposed to provide a characteristic that evokes the destination, namely the skin, that is to say the touch, the softness of the skin.
The desired touch could be achieved by applying to the surface of the leaf a layer which had expandable thermoplastic microspheres.
2 Ce brevet visait entre autre à résoudre les problèmes de machinabilité de ces feuilles lors de l'impression, notamment les problèmes de séparation de feuilles dans les piles du fait des propriétés antiglisse des microsphères ajoutées.
D'une manière générale, les papiers fins couchés soulèvent souvent de sérieux problèmes lors de l'impression ou lors d'opérations de transformation, les plus courants étant dans le cadre d'une impression offset : le poudrage et le maculage.
Le poudrage correspond au détachement de la couche sous forme de poudre sèche durant l'impression, phénomène qui peut s'accentuer avec les passages successifs de la feuille dans les machines d'impression ou de transformation.
Ce phénomène vient d'un mauvais dosage liant/pigment, le pigment étant en pourcentage trop important par rapport au liant.
Il peut provenir également de la taille et de la forme des particules de pigment.
Le maculage correspond au report d'impression d'une feuille à l'autre lors d'une mise en pile notamment.
On observe ainsi souvent au verso d'une feuille des tâches d'encre plus ou moins intenses qui proviennent de l'encre du recto de la feuille du dessous.
Lorsque l'on défait la pile, on entend plus ou moins fort le crissement des feuilles.
Ce phénomène, s'il est faible, se nomme le maculage.
C'est du piquetage si des éléments de papier participent au décollement.
C'est du collage en pile si on ne peut plus séparer les feuilles les unes des autres.
Le papier peut participer à ce phénomène du fait qu'un papier non adapté à
l'encre peut avoir une mauvaise capacité d'accueil de l'encre et qu'un papier possédant un état de surface irrégulier demande trop d'encre pour une impression correcte.
Au vu de ces considérations, la Demanderesse s'est attachée à fournir un papier ayant un toucher soyeux, couchés de préférence sur ces deux faces et ne présentant pas les problèmes d'imprimabilité et de machinabilité énoncés ci-dessus. 2 This patent aimed, among other things, to solve the problems of the machinability of these sheets during printing, including the problems of separation of leaves in batteries because of the anti-slip properties of the added microspheres.
In general, fine coated paper often raises serious problems during printing or during processing operations, more currents being in the context of offset printing: dusting and smudging.
The dusting corresponds to the detachment of the layer in powder form dries during printing, a phenomenon that can be accentuated with successive sheets in the printing or converting machines.
This phenomenon comes from a poor binding / pigment dosage, the pigment being in percentage too large compared to the binder.
It can also come from the size and shape of the particles of pigment.
The smearing corresponds to the transfer of printing from one sheet to another during stacking in particular.
This is often seen on the back of a sheet of ink tasks more or less intense that comes from the ink of the front of the sheet of the underside.
When we unpack the pile, we hear more or less loud the squealing of leaves.
This phenomenon, if it is weak, is called smearing.
This is picketing if paper elements participate in the detachment.
This is stacking if you can not separate the leaves any of the other.
Paper can contribute to this phenomenon because paper that is not suitable for the ink may have a poor capacity for ink and a paper having an irregular surface condition requires too much ink for a impression correct.
In view of these considerations, the Claimant has endeavored to provide a paper with a silky touch, preferably lying on both sides and not not presenting the printability and machinability problems set out above.
3 Un premier but de l'invention est donc de fournir une composition de couchage pour papiers couchés destinés à être imprimés en offset, caractérisée par le fait que les pigments utilisés dans la couche sont des microbilles de polyuréthanes possédant une taille moyenne inférieure à 10 micromètres, et de manière avantageuse proche de 7 micromètres.
En particulier, l'invention se caractérise par le fait que le liant utilisé
dans la couche est une émulsion aqueuse de polyuréthane, et de préférence un polyuréthane mou possédant un taux d'élongation supérieur ou égal à 500%, de façon à ce que les papiers couchés aient un toucher soyeux.
En particulier, l'invention se caractérise par le fait que le taux de liant par rapport aux pigments est supérieur ou égal à 40 % en poids sec, et de préférence supérieur ou égal à 200 %.
Un autre but de l'invention est de fournir un papier couché possédant un toucher soyeux, comportant au moins une face enduite d'une composition de couchage telle que définie ci-dessus, et de manière avantageuse ces deux faces.
Ledit papier se caractérise par le fait qu'il peut être imprimé en offset avec un maculage et un poudrage faible, voire inexistant.
Le papier est à base de fibres de cellulose, et possède un grammage compris entre 70 et 500 g/m2, de préférence entre 100 et 300 g/m2.
Selon un cas particulier, le papier est transparent ou translucide.
Plus particulièrement, le papier constitue un papier calque.
On entend par papier calque, un papier tel que défini par la norme internationale ISO 4046-1978 au point 6.94.
Plus particulièrement, l'invention se caractérise par le fait que le dit papier est un papier calque, en particulier obtenu par un raffinage poussé des fibres de cellulose le composant.
3a En particulier, l'invention se caractérise par le fait que le poids de ladite couche sur au moins l'une des faces est compris entre 2 et 10 g/m2 en sec, de préférence entre 3 et 6 g/m2.
Ledit papier se caractérise également par un coefficient de frottement dynamique entre sa face recto couchée et son autre face verso également couchée 3 A first object of the invention is therefore to provide a coating composition for coated papers intended for offset printing, characterized by the does that pigments used in the layer are microbeads of polyurethanes possessing a average size less than 10 micrometers, and advantageously close of 7 micrometers.
In particular, the invention is characterized in that the binder used in the layer is an aqueous emulsion of polyurethane, and preferably a polyurethane with an elongation rate greater than or equal to 500%, so that coated papers have a silky feel.
In particular, the invention is characterized in that the level of binder by ratio to the pigments is greater than or equal to 40% by dry weight, and preference greater than or equal to 200%.
Another object of the invention is to provide a coated paper having a silky touch, comprising at least one face coated with a composition of sleeping as defined above, and advantageously these two faces.
Said paper is characterized by the fact that it can be offset printed with a smudging and low dusting or nonexistent.
The paper is based on cellulose fibers, and has a grammage included between 70 and 500 g / m 2, preferably between 100 and 300 g / m 2.
In one particular case, the paper is transparent or translucent.
More particularly, the paper constitutes a tracing paper.
Tracing paper means a paper as defined by the standard International Standard ISO 4046-1978 in 6.94.
More particularly, the invention is characterized by the fact that the said paper is a tracing paper, in particular obtained by a refined refining of the fibers of cellulose the component.
3a In particular, the invention is characterized in that the weight of said layer on at least one of the faces is between 2 and 10 g / m2 in sec, of preferably between 3 and 6 g / m2.
Said paper is also characterized by a coefficient of friction dynamic between its front side lying and its other side also verso lying
4 inférieur ou égal à 1,0, mesure faite selon la norme NF-Q-03-082 avec un patin de 200 g.
Le coefficient de frottement dynamique reflète l'aptitude de la feuille à se bloquer au départ d'un déplacement ; plus il est élevé, plus l'amorce d'un mouvement d'une feuille dans une pile sera difficile.
Des exemples comparatifs et des exemples non limitatifs de réalisation de l'invention et d'autres avantages, éventuellement, sont décrits ci-après.
EXEMPLES :
Exemples 1 à 5 Sur une feuille de papier support ayant un grammage de 100 g/m2, plus spécifiquement la référence CONQUEROR CX 22 commercialisé par la Demanderesse, on applique, à l'aide d'une coucheuse à lame d'air, une composition comprenant des microbilles de polyuréthane de différentes tailles comme mentionné
dans le tableau 1, à raison de 5 g/m2 environ par face.
La composition comprenant des microbilles de polyuréthane est réalisée en milieu aqueux et contient en poids sec :
- 24,7 parts d'eau - 0,1 part d'agent mouillant - 33,3 parts d'une émulsion aqueuse de polyuréthane Witcobond 290 H
- 20 parts de microbilles de polyuréthane - 0,5 part de régulateur de pH
- 1 part d'épaississant.
Exemples 6 à 13 Sur une feuille de papier support ayant un grammage de 100 g/m2, plus spécifiquement la référence CONQUEROR CX 22 commercialisé par la Demanderesse, on applique, à l'aide d'une coucheuse à lame d'air, une composition comprenant des microbilles de polyuréthane de taille moyenne voisine de 7 micromètres à raison de 5 g/m2 en sec environ par face, en faisant varier le taux de liant par rapport au poids de pigment comme mentionné dans le tableau 2. 4 less than or equal to 1.0, measured according to standard NF-Q-03-082 with a skid of 200 g.
The dynamic coefficient of friction reflects the ability of the sheet to block at the start of a trip; the higher it is, the more the leader of a movement a leaf in a pile will be difficult.
Comparative examples and non-limiting examples of embodiments of the invention and other advantages, if any, are described below.
EXAMPLES
Examples 1 to 5 On a sheet of paper having a basis weight of 100 g / m2, plus specifically the reference CONQUEROR CX 22 marketed by the Applicant is applied, using an air knife coater, a composition comprising polyurethane microbeads of different sizes as mentionned in Table 1, at a rate of about 5 g / m 2 per side.
The composition comprising polyurethane microbeads is produced in aqueous medium and contains in dry weight:
- 24.7 parts of water - 0.1 parts of wetting agent - 33.3 parts of a Witcobond 290 H polyurethane aqueous emulsion - 20 parts of polyurethane microbeads - 0.5 parts of pH regulator - 1 part thickener.
Examples 6 to 13 On a sheet of paper having a basis weight of 100 g / m2, plus specifically the reference CONQUEROR CX 22 marketed by the Applicant is applied, using an air knife coater, a composition comprising medium-sized polyurethane microbeads of 7 micrometers at a rate of about 5 g / m 2 per sec, by varying the rate binder based on pigment weight as mentioned in Table 2.
5 La composition comprenant des microbilles de polyuréthane est réalisée en milieu aqueux et contient en poids sec :
parts sèches variables d'une émulsion aqueuse de polyuréthane Rolflex PAD
20 parts de microbilles de polyuréthane Daiplacoat RHU 5070 - 0,5 part de régulateur de pH
1 part d'un épaississant REALISATION DES TESTS :
On apprécie manuellement le toucher de la face comportant la couche de microbilles de polyuréthane.
- On détermine la réponse du papier vierge au test de poudrage de façon à
mettre en évidence la propension de la couche à se déliter lors d'un passage machine.
Le test de poudrage se fait de la manière suivante :
a) on applique un patin de 40 mm X 40 mm et d'un poids de 2 kg monté
sur un chariot et recouvert d'un feutre noir en tissu (mélange de 70 % laine, 30 %
polyamide) sur une ou plusieurs feuilles de papier enduites de ladite couche, b) on effectue un seul passage sur le papier de façon à couvrir une longueur totale de 6 m c) on retire le feutre du patin d) on mesure la réflectivité du feutre à l'aide d'un appareil ELREPHO (la valeur mesurée étant d'environ 1,4 pour le tissu brut) The composition comprising polyurethane microbeads is made of aqueous medium and contains in dry weight:
variable dry parts of an aqueous Rolflex polyurethane emulsion PAD
20 parts of polyurethane microbeads Daiplacoat RHU 5070 - 0.5 parts of pH regulator 1 part of a thickener REALIZATION OF THE TESTS:
We appreciate manually the touch of the face with the layer of polyurethane microbeads.
- The response of the blank paper to the dust test is determined so that highlight the propensity of the layer to disintegrate during a passage machine.
The dusting test is done as follows:
a) a shoe of 40 mm X 40 mm and a weight of 2 kg mounted is applied on a cart and covered with a black cloth felt (mix of 70% wool, 30 %
polyamide) on one or more sheets of paper coated with said layer, b) one pass on the paper to cover a length total of 6 m c) remove the felt from the skate d) the reflectivity of the felt is measured using an ELREPHO device (the measured value being about 1.4 for the raw fabric)
6 - on détermine la réponse du papier imprimé au test de maculage de façon à mettre en évidence la propension du papier à provoquer un maculage lors d'un empilage machine. Le test de maculage se fait de manière suivante :
a) on prépare des éprouvettes du papier à tester faisant 48 mm de large et 250 mm de long b) on utilise un appareil de test PRUFBAU possédant un poste n l d'impression et un poste n 2 de report d'impression c) on règle la pression du poste n 1 à 1000 N et la pression du poste n 2 à
d) on règle la vitesse de l'appareil à 0,5 m/sec e) on encre le rouleau d'encrage du poste n l durant 30 sec avec une encre bleue de type HUBER 408010 f) on place un transporteur muni d'une éprouvette devant le poste n 1 g) on place une molette non encrée sur le poste n 2 h) on imprime l'éprouvette sur le poste n 1 i) on déclenche le chronomètre immédiatement après l'impression j) on place à l'aide d'une bande adhésive une éprouvette du même papier sur la molette vierge du poste n 2 k) une fois que 120 sec se sont écoulées sur le chronomètre, on engage le transporteur muni de l'éprouvette imprimée jusqu'au niveau du blanchet 1) on sépare immédiatement l'éprouvette du poste n 2 de sa molette m) on mesure à l'aide d'un densitomètre XRITE la densité optique du cyan reporté sur l'éprouvette vierge.
RESULTATS :
Les résultats des tests pour les exemples 1 à 5 sont présentés dans le tableau 1.
On constate que, même si la plupart des papiers ont une réponse aux tests de maculage et de poudrage plutôt satisfaisant, seules des tailles de microbilles inférieures à 10 micromètres permettent d'obtenir un toucher soyeux acceptable. 6 the response of the printed paper to the smear test is determined to highlight the propensity of paper to smudge during a stacking machine. The smearing test is carried out as follows:
a) test specimens of the test paper 48 mm wide and 250 mm long b) a PRUFBAU test device is used with a position nl of printing and a post n 2 of print report c) the pressure of the station n 1 is set to 1000 N and the pressure of the station n 2 to d) set the speed of the device at 0.5 m / sec e) the ink roll of station nl is inked for 30 seconds with an ink blue HUBER type 408010 (f) a carrier fitted with a test-tube is placed in front of station No. 1 g) place a wheel not inked on the station n 2 h) the specimen is printed on station 1 i) the timer is started immediately after printing j) a test piece of the same paper is placed with the aid of an adhesive tape on the blank wheel of station 2 (k) after 120 seconds have elapsed on the stopwatch, the carrier fitted with the test specimen printed up to blanket level 1) the specimen is immediately separated from station n 2 of its wheel m) the optical density of the cyan is measured using an XRITE densitometer reported on the blank test tube.
RESULTS:
The test results for Examples 1 to 5 are shown in the table 1.
It is found that even though most papers have a response to smearing and dusting rather satisfactory, only microbead sizes less than 10 micrometers give a silky touch acceptable.
7 Les résultats des tests pour les exemples 6 à 13 permettent de conclure qu'en choisissant une taille de microbilles permettant d'obtenir le toucher soyeux voulu, il est nécessaire ensuite de choisir un taux de liant supérieur ou égal à 40 %
pour avoir un poudrage correct et supérieur ou égal à 200 % pour avoir un maculage correct.
En effet, le poudrage est jugé satisfaisant en dessous de 2 et le maculage en dessous de 0,1.
On a représenté sur les figures 1 et 2 une vue au Microscope Electronique à
Balayage d'un papier présentant du point de vue de la demanderesse un toucher soyeux.
Ce papier a été obtenu en déposant sur un papier support CONQUEROR CX
22 ayant un grammage de 100 g/m2 composition de couche suivante sur ces deux faces :
2,8 kg d'eau, 0,03 kg d'agent mouillant TEXAPON Z95P, 81 kg de liant ROLFLEX PAD commercialisé par LAMBERTI, 6,1 kg de microbilles de polyuréthane DAIPLACOAT RHU 5070 commercialisé par PROMECOME, 1 kg d'un épaississant CMC BLANOSE 7M65 à 2,5 % commercialisé par AQUALON, à raison de 5,4 g/m2 en poids sec par face, les quantités étant exprimées en poids commercial.
Le papier obtenu a été ensuite calandré.
Les photographies représentent respectivement une vue de dessus grossie 200 fois et une vue en coupe grossie 2000 fois.
Le papier obtenu présente effectivement un toucher soyeux sur ces deux faces.
En mesurant le coefficient de frottement dynamique du papier couché sur lui-même selon la norme NF-Q-03-082 avec un patin de 200 g, on obtient une valeur de 0,8 susceptible d'assurer une bonne machinabilité des feuilles sur les machines d'impression ou de transformation. 7 The test results for Examples 6 to 13 allow us to conclude that choosing a size of microbeads to obtain the silky touch wanted, he is then necessary to choose a binder rate greater than or equal to 40%
to get correct dusting and greater than or equal to 200% for smearing correct.
Indeed, the dusting is considered satisfactory below 2 and the smearing in below 0.1.
FIGS. 1 and 2 show an electron microscope view at Sweeping a paper presenting from the point of view of the plaintiff a touch silky.
This paper was obtained by depositing on a CONQUEROR CX paper 22 having a basis weight of 100 g / m2 next layer composition on these two faces:
2.8 kg of water, 0.03 kg wetting agent TEXAPON Z95P, 81 kg of ROLFLEX PAD binder marketed by LAMBERTI, 6.1 kg of DAIPLACOAT RHU 5070 polyurethane microbeads marketed by PROMECOME, 1 kg of a 2.5% CMC BLANOSE 7M65 thickener marketed by Aqualon, at a rate of 5.4 g / m 2 by dry weight per side, the quantities being expressed in commercial weight.
The paper obtained was then calendered.
The photographs respectively represent a magnified top view 200 times and a magnified sectional view 2000 times.
The paper obtained actually has a silky touch on both sides.
By measuring the dynamic coefficient of friction of the paper coated on it even according to the standard NF-Q-03-082 with a pad of 200 g, we obtain a value of 0.8 likely to ensure a good machinability of the leaves on the machinery printing or processing.
