Definitions
- the present invention relates to a transparent paper and / or translucent intense color, more particularly a tracing paper of intense color or a transparent paper of intense color.
- Tansparent or translucent papers are also known colored or not obtained from initially opaque paper using very hot calendering.
- This kind of paper called “crystal paper” or “glassine” is easily recognizable by the very high smoothness of its surface. Said smoothed being the direct consequence of the crushing to which he was subjected in the grille to make it transparent. Measurement of smoothness according to Bekk typically exceeds 2,000 seconds for papers of this kind.
- the technique used to make the base paper does not make call for a very advanced refining of the fibers before the formation of the leaves.
- a paper is colored, the fixation of the dyes on the fibers is not not favored and it's hard to get a paper having a color intense.
- DE-C-603 554 discloses a method of manufacturing printing paper, cardboard for printing or other cartons by assembly of unfinished paper sheets, wet, containing dyes or fillers with usual paper layers. This The process is such that fillers or dyes are added according to a amount of once or twice the dry weight of the fibers and thus laminates layers of paper. This document therefore concerns the manufacture of paper or cardboard that have multiple layers of fiber. In no way, this document only concerns the manufacture of a tracing paper colored.
- EP-A-0 097 371 relates to a manufacturing process of paper or other similar products by suspending fibrous material in a pulper, grinding the pulp to shorten, fibrillate and hydrate the fibers, possibly the mixture of the mass of fibers obtained with additives, dyes and / or binders, and on a grid, this method being characterized in that it replaces from 10 to 35% by weight of cellulose with reinforcing agents.
- These reinforcing agents can be reinforcing agents based corn, rice and wheat. Therefore, this document does not concern absolutely not making a layer. It only describes the manufacture of a paper with possibly mass dyes and with additives based on corn, rice, etc.
- US-A-2 128 739 relates to a laminated paper manufactured from two sheets of paper between which a film is interposed of wax. This gives a laminated sheet that is resistant to grease and moisture. It is possible to introduce a colored or tinted product in the fiber suspension.
- This document describes the coloring of a paper during the process of papermaking by adding a dye. It is well mentioned that the gloss and opacity of the paper is maintained. We carry out the control of the coloring of the paper with the brightness value L, the value a of difference in color between red and green and the value b which is the difference value between yellow and blue. This document does not describe absolutely not the manufacture of a colored tracing paper. He describes only the way in which colorings of a paper can be adjusted measuring L, a and b.
- DE-C-250 533 relates to a process for staining of the paper in mass.
- the dye solution is brought from the headbox using a hose.
- JP-A-49 125 614 describes the reduction of wood pulp in the presence of a hydrosulphite reducing agent and sodium hydroxide. We blend the pulp with a water soluble dye. It is not therefore a question of method of manufacturing a tracing paper.
- the present invention aims to provide a translucent paper and / or transparent made of very refined fibers to a very Schöpper degree high, at least greater than 80 or a medium-transparent paper of a chemical composition that has an intense color and that has a Bekk smoothness of less than 2,000 seconds, preferably less than at 30 seconds, whose cellulose is 100% in the form of fibers and which is usable in the field of printing and / or writing.
- the present invention also aims at providing a tracing paper comprising a high percentage of dye.
- the present invention also aims to provide a very tracing paper colorful having a good look.
- the invention also aims to provide a method of manufacturing a very colored tracing paper or a very colored transparent paper.
- One way is to double-sided printing on the paper.
- the inventors have carried out numerous tests consisting in make such an impression on the top and the bottom a translucent / and or transparent paper, more particularly a paper layer obtained with very refined fibers.
- a printing on the sides of a sheet of tracing paper whether it be a flexographic, heliographic or offset printing, transparency is heavily altered and the printability is degraded.
- a second way to color a paper is to perform a sleeping on the upper and lower faces, this sleeping being performed with a composition containing dyes, fillers and a binder.
- the inventors therefore made a coating of a paper translucent / and or transparent with a colored composition.
- the more we increase the percentage of dye the more we lose the transparency.
- a third way to color a paper is to introduce a dye in the aqueous suspension of cellulosic fibers. This The technique can only be used if the dye is introduced into the upstream part of the circuits where the pulp is mixed with the water and other traditional constituents of paper. Indeed, it is necessary that the dye remains in contact with the cellulosic fibers for a time sufficient for the dye to attach to the fibers.
- the skilled person know that if we increase the amount of dye, only a certain part of dye gets fixed on the fibers because once the fiber sites are When the dye is used, no more dye can be fixed. The skilled person therefore thinks that it is impossible to fix more than about 5% by weight of liquid dye relative to the finished paper. In addition, more dye is introduced, the more it is rejected in the sewage, which causes a pollution of the circuits of the machine and of the environment.
- a fourth way is to color the tracing paper after dryer rolls, in size-press.
- such a method does not allow not to get an intense shade of paper.
- the inventors have obtained such a paper, surprisingly, by refining the pulp to a Schöpper degree at least greater than 80, and introducing the dye just before the headbox, i.e. well downstream of the pulper, contrary to what has always been done traditional way for intense coloring.
- Paper has from 5 to 10% by weight of liquid dye relative to the weight of paper finished.
- the inventors believe that that the fibers are very refined, that is to say that they contain numerous fibrils, the number of dye binding sites is increased and that for the same weight of paper obtained with fibers unrefined, the amount of dyestuff can be increased up to 4 times.
- the fibers are very refined, one can introduce the dye into the headbox because it is not necessary for the contact time between the fibers and the dye is very long, the fibers having many dye binding sites, due to the presence of many fibrils.
- the pulp is refined to a Schöpper degree from 50 to 80.
- the temperature of the fibrous suspension between approximately 80 and 100 ° C to allow a better drainage of the leaf of paper. These relatively high temperatures are very favorable to fixing dyes on the fibers.
- the inventors have surprisingly prepared a paper transparent in intense color by producing an aqueous suspension of fibers and a water-soluble dye, by depositing the said hanging on a flat table of a paper machine, removing the water by gravity, then drying the sheet between drying rollers, depositing on the sheet thus dried a chemical composition of transparency and finally drying the leaf.
- the introduction of the dye in the headbox avoids polluting the part of the machine between the pulper and the headbox.
- the dye is retained by the fibrils, the water out of the drain contains very little dye, and so the pollution is diminished.
- each dye particle plays a visible role.
- the dye that is in the mass of the paper is visible.
- only the dye on the surface of the paper is visible, and therefore, to have an intense shade, it is necessary to introduce a lot more dye.
- the invention further relates to a transparent paper and / or translucent having a mass dye introduced into a headbox on which a dye has been deposited in an aqueous medium in a size press, for obtain an increase in intensity when using the same dye and material effects when using a different dye.
- the invention further relates to a transparent paper and / or translucent material comprising a mass or size press a fluorescent dye and possibly one or more other soluble dyes in the water.
- Figure 1 is a diagram representing coordinates obtained with a color measuring device for papers according to the invention.
- Figure 2 is a diagram showing the abscissa values of L and ordinate the values of c for papers according to the invention and papers of the prior art.
- the hues are characterized by a polar coordinate system L, c, H. It can also be used a system of orthogonal coordinates L, a, b.
- the first parameter L is the brightness of the hue. It is worth between 0 and 100 and indicates whether the hue is dark (0) or light (100).
- the brightness L on the abscissa and the saturation c on the ordinate are defined.
- White papers as well as papers of light shades and little are located in the sector at the bottom right of the graph of the Figure 2 and are represented by squares. They are not part of this invention. Tracing or transparency papers with bright colors and very saturated which are the subject of the present invention are found in the area at the top right of the graph of Figure 2; the tracing papers or transparencies having dark hues according to the present invention found in the left part of the graph.
- the papers according to this The invention is represented by dots on the graph of FIG.
- Fibers are suspended in water in a pulper long-lasting pulp from softwoods, and refined in a refiner until a Schöpper degree of 60 is obtained.
- temperature of the aqueous fiber suspension at a temperature of 80-100 ° C.
- the aqueous suspension of fibers is deposited on the canvas of a flat-table paper machine, the water is removed by gravity.
- the relatively high temperature of the aqueous suspension is necessary to remove the water by gravity, the fibers having a great affinity for water due to the presence of many fibrils.
- we press the leaf to remove the residual water The sheet is then dried between drying rolls. We then obtain a paper transparent. This paper is a traditional colored tracing paper greyish.
- An ink composed of a binder, a solvent and 15% is prepared by weight of a blue dye.
- the paper has lost its transparency. he can have some appearance defects due to printing.
- the coloring is not not homogeneous.
- Printing an ink on the paper changes the state of surface, so printability. Tracing paper printed with ink fat including the dye is more difficult to print.
- a tracing paper is prepared as in Comparative Example 1.
- An aqueous composition containing the dye is then prepared. fillers and a latex. This composition is then deposited by coating on both sides.
- the coating of a tracing paper would result in very important tiling of the paper.
- Fibers are suspended in water in a pulper long-lasting pulp from softwoods, and refined in a refiner until a Schöpper degree of 60 is obtained.
- temperature of the aqueous fiber suspension at a temperature of 80-100 ° C.
- one introduced into the aqueous suspension of fibers a blue dye in aqueous solution, the amount of dye being such that it is 6% weight relative to the weight of the finished dry paper.
- the dye is a dye directly attached to cellulose, brand CARTASOL ®, blue reference 3RF, manufactured and sold by Clariant (Switzerland).
- Clariant Clariant
- the water coming out of the machine is very light, which shows that the dye is well fixed on the fibers. Then, the sheet is dried between drying rolls. We gets a transparent and / or translucent paper that has a blue color dark. The weight of dye relative to the weight of finished paper is greater than 5%.
- the color of the paper obtained is measured using, for example, a apparatus manufactured by Hunterlab. Such a device allows measure the Cartesian coordinates in three directions a, b, L of a point P of a color. So the point P is spotted according to the four colors blue, red, yellow and green. If a is positive, the color draws toward the red, if a is negative, the color is greener. If b is positive, the color draws yellow, if b is negative, the color is bluer. On the face, the point P represents a rather red color and a little yellow, it is therefore an orange color.
- the third coordinate, perpendicular to the plane of a and b, represents the brightness of the color.
- the Hunterlab device also allows you to measure coordinates of the point P.
- the distance between the center O and the point P is c and called chroma. It represents the intensity of the color.
- the angle H allows to locate the point P with respect to the four colors yellow, red, Blue green.
- a transparent paper is prepared in the same way as in Example 1, but a red dye is added at the headbox which is a dye from Clariant, the same brand as Example 1 and Reference 2RF.
- the amount of dye is 10% weight relative to the weight of the finished paper.
- Papers are made in the same manner as in Example 1, using 5GFN and RF yellow dyes from Clariant and the same brand as those of the previous examples. They are mixed with the red 2RF dye to obtain a yellow, or orange or carmine hue. The color of the obtained papers is measured in the same manner as in the previous examples. The results are given in the following Table I. Ex. No.
- Papers are made in the same manner as in Example 1, using other dyes mentioned in the following Table II.
- a paper is prepared as in Example 2 by introducing the dye in the headbox. Then in size press, we put a dye red in aqueous solution. A red paper is obtained, the ratio c / 1 is 90%, hue more intense than in Example 2.
- the papers according to the invention are located in the part upper left from right A and right C, and preferably from right B and right D.
- Papers such as L> 60 and c / L ⁇ 50% simultaneously are located in the lower right part of the diagram and are papers from the prior art.
