Definitions

  • the invention relates to a cellulose-containing filler for paper, tissue or paperboard products and to production processes therefor, and to a paper, tissue or paperboard product containing such a filler or dry mixture used therefor according to the preambles of claims 1, 39, 52 and 38, respectively.
  • cellulosic fibers made from various vegetable raw materials have been used as the raw material for the production of paper and cardboard.
  • Today almost exclusively cellulose fibers are used, which are obtained from wood. What they all have in common is that they are long-fiber products produced in a wet process. Due to the large fiber length is a good Composite achieved in the paper and cardboard, which leads to sheet formation and which is of mechanical importance of the highest importance.
  • These long-fiber products are the basis of paper and board production; Without them, no paper or cardboard can be produced. Their bond leads to the necessary sheet formation. They can differ in the degree of purity and in the fiber structure (freeness 0 SR). Highly purified, lignin-free celluloses are known as well as lignin-containing fibers (groundwood, CTMP) and recycled fibers, which are obtained from waste paper and are accordingly still contaminated with various impurities.
  • Finely divided products such as native starch, calcium carbonate, kaolin or titanium dioxide were ⁇ used for various reasons in the production process of paperboard and Textilfabri ⁇ ken. Due to their small particle size, these products are easily washed out of the paper web. Additional measures are needed to achieve retention in the paper web, at least to some extent. But this involves higher costs and other technological disadvantages. According to Lite ⁇ raturan composite can be found on high-speed paper machines (> 1500 m / min) currently despite polymeric retention agents often below 40% retention of fillers and pigments.
  • the invention binds additives for paper, tissue or paperboard production to the cellulosic component of the filler, so that they also adhere to a considerable extent to the fibers in aqueous suspensions. It is also possible to use liquid substrates, such as wet strength agents or optical brighteners, which are used in the paper formulations anyway. Since these fibers are coarse enough to remain in the paper web without additional effort, the finely divided components adhering to the surface are also held in the paper web.
  • the new development according to the invention gives better retention on the sheet former.
  • the fixation reduces the amount of expensive additives and reduces the wastewater load.
  • complex processes such as starch coking or size press are replaced by simpler processes in the paper mill.
  • the filler according to the invention comprises cellulose, lignoceilulose or microcrystalline cellulose (ie a cellulosic component), this also means cellulosic precursors or intermediates which also comprise other herbal ingredients, such as protein, protein, starch and / or mineral constituents and other. It is therefore not absolutely necessary to drive too far a chemical treatment of the vegetable raw material. Rather, vegetable ingredients may be included in the cellulosic component, the proportion of which should not exceed 25% of the total cellulosic component.
  • the particle sizes of the cellulosic component will preferably be limited to not more than 1 mm particle size, preferably not more than 0.5 mm particle size, with no restriction being required for smaller particle sizes, since nanoscale particle sizes can also be used successfully.
  • the particle sizes are preferably not more than 0.1 mm, preferably not more than 0.05 mm. Again, a limitation of the particle size down is not required. Rather, care must be taken that the particle size of the additives used is generally lower, preferably considerably less than the particle size of the cellulosic component.
  • the mass ratio between the cellulosic component and the additive component is preferably not less than 1 to 10 and particularly preferably not less than 2 to 10. No limitation is required in the direction of relatively large mass ratios, since in some circumstances very small amounts of additive may suffice. to achieve the desired effect in paper, tissue or board production. Otherwise, it is also possible to apply the additives in several layers to the particles of the cellulosic component. This makes it possible to achieve very small mass ratios of cellulosic component to additive component. As additives, as mentioned in more detail below, not only additives in pure form come into consideration.
  • raw materials containing the additive can also be introduced into the production process of the filler according to the invention, so that the raw material preparation and the fixing or coating of the additives on the particles of the cellulosic component take place in one working process.
  • starchy raw materials such as soft wheat semolina, oat bran fractions, and extruded or cooked pregelatinized starches can be used to increase the strength of the paper or board on the one hand or the internal bond between fiber and coating on the other hand
  • nanodisperse celluloses for example based on a microcrystalline cellulose, can be used in order to provide a carrier for coating compositions, for example for optical brighteners, to additives such as polyvinyl alcohol, spray starch and CMC at least partially replace and improve the printability.
  • the following fillers have the common concept of using cellulose fibers, in particular those of the applicant, as a carrier for traditional papermaking additives, in order to increase the effectiveness of the additives, to reduce their consumption and to reduce COD wastewater loads:
  • a novel sizing compound consisting of fibers and a sizing complex that enhances the hydrophobicity and / or oleophobicity of the papers and cardboards, the durability and uniformity of sizing, and the retention of the sizing agent in sheet formation.

  • a novel mineral compound consisting of fibers and minerals (fillers, pigments).

  • the lightweight filler can reduce the volume of the paper, the machine speed and the filler
  • a novel starch compound which consists of fibers and native or cationic starch and can increase the strength values (mesh burst strength, PIy Bond ply strength, Tear Index, Tensile Index, tearing length,%) With identical grammage, or one Reduction of the grammage without strength losses zuiässt.

  • the starch on the fiber may be partially pregelatinised or homogenized with the fiber or in turn consist of starch mixtures. The modification of the fiber with starch leads to an improvement of the mechanical strength of the fiber composite in the end product.
