Definitions

  • the invention relates to a method for producing a thin printing paper paper made by the process and the use of the paper.
  • Thin printing papers are mainly used for the printing of reference and Catalog works used, for example phone books, mail order catalogs and the like.
  • the latter are also called LWC papers (low-weight coated) or in the lowest Basis weight range referred to as ULWC papers (ultra-low-weight-coated).
  • LWC papers low-weight coated
  • ULWC papers ultra-low-weight-coated
  • Papers with an ever lower mass per unit area are not only made from Environmental reasons required to increase the amount of waste paper reduce, but primarily for reasons of freight cost savings when Paper transport and the reduction of postage costs when sending Printed matter, for example mail order catalogs, because one lightweight paper is the information area per unit weight of paper is bigger.
  • the reduction in the mass per unit area of printing paper is made up of two Limits set limits, namely on the one hand for reasons of still acceptable Strength of the paper, to which it is based both in its own production in a Paper making machine as well as processing on modern ones arrives at high-speed rotary printing presses, and on the other
  • printing opacity which do not fall below certain values allowed so that the paper can be printed on two sides without a print image shines through from one side to the other.
  • Higher opacity can be found in the generally due to a higher proportion of wood pulp or filler pigments
  • Raw paper or more coating mass on the paper achieve what at same paper mass per unit area but affects paper strength, because the strength-forming proportion of long-fiber paper pulp in the Rule must be reduced.
  • Coated papers are more expensive to produce than natural papers, they show also a smoother surface that better reflects the printed image, disadvantageous for reasons of environmental pollution and therefore also for reprocessing synthetic binders used in the coating compositions in the form of a cured polymer dispersion.
  • Coated papers are very low Weight per unit area due to the lower proportion of base paper and partly due to the Use of the synthetic binder, often very lobular, which is disadvantageous for the Handling can be. If you go with uncoated natural papers low grammages, so print opacity and print brilliance (Print gloss) and the bleeding through of the printing ink increases. This one known papers do not have a subsequent coating, the opacity only by increasing the filler or wood pulp content in the paper itself be improved.
  • paper strength is not only determined by Art and treatment of the paper pulp used, but among other things also through the uniformity of the paper sheet formation in the Paper production machine, because weaknesses with increased uniformity lower strength are reduced, which in the end for triggering a Tear or breakage of the paper web are responsible.
  • a Uneven sheet formation generally leads to more uneven Ink absorption, which causes the closeness of the print image to suffer.
  • bulk printing papers are not made from pure cellulose either made that would give the highest paper strength in itself, but it becomes as much mechanically or thermo-mechanically open-minded as possible Wood pulp or wood pulp used, which not only has cost advantages, but also besides also the paper opacity improved and positive on the achievable print result affects.
  • the wood sanding reduces the achievable Paper strength that could be obtained using pure pulp.
  • the price situation for bulk printing papers is such that such papers Cost-covering only on very powerful, fast production machines can be produced.
  • the invention has for its object to provide a method for producing a thin printing paper, the mass per unit area is below 49 g / m 2 , which is essentially free of synthetic binders, one in comparison to conventional natural papers in the range of over 50 g / m 2 comparable, if not better print quality and sufficient rigidity and strength to be produced at high machine speed and processed in conventional rotary printing presses.

  • the new paper has despite the small mass per unit area of a total pulp content of less than 40% by weight.
  • the proportion of pulp in the fiber composition of a paper can be determine microscopically or indirectly chemically. These methods are in the Paper inspection known. A microscopic method of determination defined counting of fibers in a microscopic image one out of one The fiber suspension obtained from the paper sample is specified in the US test method TAPPI T 401 om-82. In the indirect chemical determination of The proportion of cellulose is determined by means of a lignin determination chemically digested fibers and the pulp then determined as Difference calculated. Hägglund's lignin determination method is used for this applied.
  • the strength-giving pulp consists of fresh pulp, generally from long-fiber softwood pulp and the rest of the pulp from ground wood or wood pulp.
  • Embodiment of the invention should, based on total fiber material, at least 15 % By weight of a fibrous material used from the processing of Waste paper is won. This proportion should preferably even exceed 35% by weight. be.
  • Waste paper is not to be understood here as waste paper that occurs during of the manufacturing process and returned in the cycle and again be dissolved because these wastes have the same composition as the new fiber. Rather, waste paper should be mixed waste paper, in particular household goods and deinking goods are understood, which is based on bought the market and again in a special waste paper processing plant is processed.
  • waste paper pulp in general itself contains a certain proportion of pulp, through which a corresponding proportion of pulp can be replaced from fresh pulp.
  • a pulp just below 40% and a proportion of waste paper fibers of around 70% therefore close not logically mutually exclusive.
  • waste paper in a paper of the marked here Art was not common until now.
  • the use of waste paper can result in a cause slight graying of the base paper, which according to the invention by Measures to be described below is compensated.
  • the base paper In order to impart sufficient opacity to the paper according to the invention, the base paper already has an ash content of> 8% by weight.

  • the sheet formation for the base paper takes place on a Paper making machine, whose screening speed is more than 700 m / min is.
  • good leaf formation is necessary in order to With low basis weights, there is still sufficient paper strength achieve.
  • the lower the basis weight the better the leaf formation should be be.
  • Base paper preferably uses a wire section, at least in the form of a So-called.
  • Hybrid former is formed, a wire section with a second or Upper screen, which is attached to the lower screen shortly after the formation of the sheet is brought together so that the freshly formed paper web for their further double-sided drainage between the two screens.
  • a so-called gap former in which the top sieve already Merged with the bottom sieve immediately after the material suspension emerges is, so that already the first sheet formation in the converging gap between these two endlessly rotating sieves with double-sided drainage.

  • the use of a Film press preferred for surface coating leads to relatively short contact times of the base paper with the coating color, because the application quantity is pre-metered onto the application rollers and the paper only directly in the nip with the correct amount of ink and not with one Comes into contact with excess which, as in the doctor blade method, must be scraped off the paper itself.

  • Strength, as used preferably according to the invention normally reduces the Compressibility of the paper matrix and leads to stroke contraction at the Drying, which is why the necessary for optimal gravure ink transfer Surface smoothness and paper softness are partially lost.
  • Printing papers with a pure starch-kaolin line is not suitable for gravure printing.
  • the web offset printing process is due to high Ink viscosity and drawstring significantly higher demands on the Line binding as the gravure process, which is why in LWC coating color formulations for offset papers, binder content from 13 to 20%, mostly plastic binders mixed with starch are common. That with only 8% absolutely strengthened surface coating under practical conditions without problems, i.e. without blanket covers, by a Multi-color offset press runs, all the more astonishing because of its strength in the Binding force scale behind polyvinyl alcohol, synthetic binders and CMC ranked. The combination of the natural organic binder with the Sodium bentonite appears to have a special effect.
