Description of the invention: [Technical field to which the invention pertains] [_ The present invention relates to a method for enhancing the internal bonding strength of paper and paper products. [Prior Art 3 _ _ Bond strength means the ability of paper to resist stress in the thickness direction of the paper. When the strength of the paper/paperboard in the z direction is exceeded, even if the surface _ is , the structure of the paper collapses. This internal bond strength is a particularly important feature in the printing of paper products as well as: board 0. The internal bond strength can be measured by various physical tests according to the τ 569 Pm-00 standard, such as the “ο” bond test, for example in lithographic and paperboard processing, at the stage of wrinkling, folding and coating. 'Paper/paperboard is exposed to great forces in its cross machine direction' because of its use with manufacturers or especially printing paper and paperboard, their internal bond strength should therefore be sufficient. 0 Various methods can be used to enhance the internal bond strength of the paper product, such as by paying attention to web formation, wet pressing, and fiber orientation, or by increasing the strength of the fiber bonds, such as by adding various chemical fillers or additives, Or by refining the pulp. In this regard, it is also known to enhance the strength characteristics of wood pulp or recycled pulp, e.g., internal bond strength, by mixing fractionated non-wood pulp or wood pulp with the pulp. Control of bagasse pulp 099135961 Form No. A0101 in El-Sharkawy, K., Rousu, P., Haavisto, s. & Paulapuro, H., Appita Journal 60(5), 2007, 404 to 409, 415 3 page/total 23 pages 1003021897-0 201118215 quality by fractionation and refining" describes the addition of fractionated bagasse pulp to softwood pulp, which is then refined together with the softwood pulp. The fractionation of the bagasse pulp is carried out by pressure sieving fractionation' from which the approved product and the waste fraction are obtained. It is mentioned that the waste fraction mainly comprises long and coarse fibers, and the approved fraction mainly comprises short fibers, fine and some fine fibers. Different amounts of this approved fraction were added to the softwood pulp prior to refining the pulp. The cockroaches that it found were added to the paper edge to increase the density of the paper. It also claims that this leads to enhanced internal bond strength" in "Upgrading of Recycled paper with" in Wanrosli, WD, Zainuddin, Z. & Roslan, S., Industrial Crops and Products 21(3), 2005, 325 to 329 Oil palm fibre soda pulp" describes the addition of oil palm pulp to recycled pulp. It was found that the tensile strength and the tear strength of the recycled pulp were enhanced after the addition of 2% unrefined oil palm paper or 10% refined oil standard pulp. In Sood, YV, Tyagi, S., Payra, I., Neethikumar, R., Tyagi, R., Kumar, A. & Kulkarni, AG, Cellulose Chem. Technol., 41 (1), 7 7 to 8 "F iberfracti ο na — tion as a tool for making better quality paper from agricultural residues pulp" in 3 (2 0 0 7), which discloses the fractionation of bleached pulp. The bleached pulp contains a mixture of 90% straw pulp and bagasse pulp. And 10% hardwood pulp. The pulp was fractionated into two fractions, the accumulator and the waste, by a Bauer McNett unit (hole size: 297 min). The waste fraction was refined and from two fractions, using 099135961 Form No. A0101 4 pages / total 23 pages 1003021897-0 201118215 Laboratory paper mold to prepare laboratory paper. A three-layer paper is produced using the obtained paper by sandwiching paper made of the embossed material between two sheets of paper made of the waste. It has been found that the three-ply paper thus obtained has improved 'e.g. tensile and tear strength, amount and stiffness. It has also been found that it is possible to improve the strength of the intermediate layer of the three-layer paperboard by using a fine fraction of birch cellulose fractionated by a hydrocyclone instead of a mixture of chemical thermomechanical pulp and long-fiber cellulose. ( Panula-Ontto, S. & Fuhrmann, A., "Effect of fractionation and refining on board and tensile stiffness 〇f board". SP-2 Sustain- pack seminar. Latest innovation in cellulose packaging,Ver〇na,Haly , 18 AprU 2〇〇7). The refined birch cellulose pulp is used. It is also known that the non-woody component can have a positive and negative carcass effect on the properties of the overall pulp. For example, it is only necessary to remove the fine parts of the J-knife of the specific class ^, and to improve the drainage capacity of the bee pulp and the π degree (FI Patent Application No. 5 (5) 35 is published on April 18, 2008). The problem with the above-described method is that the non-wood pulp composition is not smashed to make the internal bond strength of the paper and the paper product capable of being added by adding non-wood pulp. Way to enhance. For example, the additional refining stage is also intended to be a desired one.

Preferred embodiments of the present invention are disclosed in the scope of the appended claims. SUMMARY OF THE INVENTION The present invention is directed to a method of enhancing the internal bond strength of paper produced from the wood pulp by adding a particular type of non-wood pulp composition to the wood pulp. In accordance with the present invention, it has been discovered that a particular type of non-wood pulp significantly enhances the internal bond strength of the paper when mixed with wood pulp without substantially affecting other paper technical characteristics. It has been found that in particular a particular type of straw pulp composition is a good source of internal bond strength. An advantage of the method according to the invention is that an additional refining stage can be avoided without the need for additional chemical additives or additional ingredients. Definitions of the Invention "Thin wall cells" means parenchyma cells and the like, such as non-wood pulp. "Epidermal cells j means epidermal cells and the like, and non-wood pulp. "Approved" and "accredited fraction" means fractions that have passed through a screen or sieve, or have been used as a hydrocyclone by a hydrocyclone. The museum of the top product. “Waste” and “waste fraction” mean the fraction that has been left on the screen or sieve, or the product of the bottom of the hydrocyclone in the hydrocyclone. Unless otherwise stated, the amounts, ratios, and ratios of the ingredients have been calculated by weight. [Embodiment] [0004] 099135961 The present invention relates to an increase in the production of wood pulp by adding a non-wood pulp composition to wood pulp. The method of the internal bond strength of the paper, the non-wood pulp form No. A0101, page 6 of 23, 201118215 The composition has the following characteristics: · It contains fibers, parenchyma cells, and epidermal cells' length/width ratio of the fiber Falling in the range of 40 to 150, the length/width ratio of the parenchyma cells falls within the range of 1 to 20, and the length/width ratio of the epidermal cells falls within the range of 1 to 20, and when by weight The amount of the fiber is at least 25%, preferably at least 33% of the total non-wood pulp composition, the amount of the parenchyma cells being 20 to 35% of the total non-wood pulp composition, and the amount of the epidermal cells It is 10 to 25% of the total non-wood pulp composition.较佳 In a preferred embodiment of the invention, the amount of the parenchyma cells in the composition is greater than the amount of the epidermal cells. The non-wood pulp composition also contains small amounts of other common non-wood villocyte types, such as various catheter molecules, tracheids, cork cells, and hair cells. The ratio of the non-wood pulp composition to be added when calculated from the wood pulp is from 5 to 35% 'preferably from 15 to 25%, most preferably from 25 to 35%. Ο The non-wood pulp composition can be added to the wood pulp at a suitable stage before the manufacture of the paper. It can be added to bleached or unbleached papers. Typically, the non-wood pulp composition used for incorporation is produced by residual chemical non-wood pulp. This fractionation can be carried out using fractional distillation based on, for example, screening and classification of the pressure difference. Suitable industrial devices for these include screens, sieves, such as pressure screens, and hydrocyclones (eddy current cleaners). The pressure screen can be, for example, a mesh screen. In a specific embodiment of the invention, the eight-distillation is carried out using a hydrocyclone fractionation. Preferably, the hydrocyclone is fractionated by a hydrocyclone,: 099135961 Form No. A0101, page 7 / 23 pages & 4亍1〇〇3〇21897, 〇201118215, the diameter of the hydrocyclone is 30 Up to 70 mm, for example 30 to 50 mm or 50 to 70 mm In another embodiment of the invention, pressure mesh fractionation is used for the separation. 5毫米的范围内。 The size of the hole is preferably in the range of 0.15 to 0. 6 mm. In a preferred embodiment of the invention, a combination of pressure screen fractionation and hydrocyclone fractionation is used. First, the pressure sieve is fractionated to be an approved product and waste, and then the approved product is further fractionated into an approved product and waste by using a hydrocyclone. The approved product separated from the pressure-colvested fractionation by the hydrocyclone is re-acquired and added to the wood pulp. In still another embodiment of the invention, the accumulator separated from the pressure screen by the hydrocyclone is re-acquired and added to the wood pulp. When a combination of a pressure screen fractionation and a hydrocyclone fractionation is used, it is preferred to use a pressure sieve having a pore size of from 0.15 to 0.6 mm to carry out the pressure sieve fractionation. Fractionation of the accumulator obtained by fractional distillation from the pressure screen is preferably carried out using a hydrocyclone having a diameter of 30 to 50 mm. It is preferable to use a hydrocyclone having a diameter of 50 to 70 mm to carry out the branching of the waste obtained by fractionating the pressure sieve. It was found that fine fibers (the fiber length/width ratio in the range of 40 to 150) and a positive ratio of parenchyma cells to epidermal cells (the amount of parenchyma cells is larger than the amount of epidermal cells) for the internal bonding strength Has a positive effect. The certified fraction of the hydrocyclone fractionation is a typical representative of such a composition. The fraction that has also passed through the pressure screen prior to the hydrocyclone stage has even a stronger positive effect on the internal bond strength. 099135961 Form No. A0101 Page 8 of 23 1003021897-0 201118215 If the pulp drainage capacity is critical, the approval from the pressure screen waste by the hydraulic cyclone can be used to enhance the internal key The knot strength, since the fraction has no effect on the drainage capacity of the pulp. In the process according to the invention, the non-wood pulp composition is added to the unrefined wood. The non-wood pulp composition is also not refined with the wood pulp. According to another aspect of the present invention, the present invention relates to a method of entanglement of internal bond strength of a paper by adding a non-wood pulp composition to a wood pulp, the paper being produced from the wood pulp, the non-wood pulp composition Obtained by fractionating the non-wood pulp by a hydrocyclone having a diameter of 30 to 7 Torr, by regaining the hydraulic cyclone approval, and when calculating from the wood pulp, 5 to 35 The amount of %, preferably 15 to 25%, is preferably 25 to 35% by adding the hydrocyclone approval to the wood pulp.

According to Shuming, the paper and paper production = can be any paper product, including cardboard. Particularly preferably, the present invention is suitable for the manufacture of printing paper and coated paper, for example, different types of magazine form numbers, 月ίοι = month, for manufacturing by adding the above non-wood pulp composition to wood pulp. . The preferred embodiment of this aspect is the same as the specific embodiment described above. This (4) also relates to the manufacture of paper products by making the mixed pulp obtained therefrom, and the pulp contains wood and the non-wood pulp composition described above. The invention also relates to the use of the above non-wood pulp compositions for the manufacture of pulp, paper and other paper products. The preferred embodiment of this aspect is identical to the specific embodiment described above. The following examples are presented to clarify, not limit, the invention. Example 1. Internal bond strength of straw pulp and its different fractions First, the straw pulp is fractionated into two fractions by fine pressure sieve (hole size 〇. 2 mm), ie fractionated into approved and discarded. The approval is a fine fraction that passes through the pressure screen and the waste does not pass through the pressure screen. Next, using a hydrocyclone, both fractions were further divided into two fractions, resulting in a total of four different fractions: the pressure screen accredited by a hydrocyclone (a diameter of about 40 mm ja flow rate 1.4 Ι / s) Divided into accredited (PS accredited ~ HC accredited) and waste (PS accredited - HC waste)' and the pressure screen waste is hydrocyclone (diameter about 60 mm ja flow fan 2. 〇i / s) divided into accredited materials (ps waste - HC accumulators) and waste (ps waste - Hc waste) Table 1 shows the weight ratio of the pulp fraction on the total pulp, and Table 2 shows the cell type Composition. This cell type was determined according to the I s 〇 9184_ 1 _7 standard by using Fiber Atlas in Marja-Sisko ilvessab-pu ffli for identification. More than 5,000 cells were counted from each sample. Table 1.

The pressure screen approval clearly contains less actual fibers and more parenchyma cells and epidermal cells than the pressure screen waste. Most of the conduit molecules were found in the pressure screen waste that ended in the hydrocyclone approval. Most of the thin wall and epidermal cells are found in the pressure screen approvals that end in the hydrocyclone waste. Half of the fractions ending in the pressure screen and the hydrocyclone accredited contain fine fibers 099135961 Form No. A0101 Page 13 of 23 1003021897-0 201118215, and the Dessert also contains a large number of parenchyma cells and epidermal cells. The hydrocyclone affects the fractionation of the pressure screen accreditation such that the hydrocyclone accredit contains relatively more fibers than the waste, and the largest portion of the waste is comprised of epidermal cells. Laboratory paper is prepared from the original pulp and different pulp fractions in a laboratory paper mold. Table 3 shows the length, width, fineness, length/width ratio, linear density, and internal Scott bond strength of the virgin pulp with the different pulp fractions. The Lorenz-Wettre fiber analyzer was used to determine the cell size, and the width of the fiber was determined by microscopy. The Scott bond strength is determined by the T 569 PM 00 standard. In Table 3, the definition L(l) means the length-weighted fiber length, and L(n) means the calculated fiber length. 099135961 Form No. A0101 Page 14 of 23 1003021897-0 201118215[0006] Table 3.

The internal bond strength indicates that the internal bond strength of the original pulp is lower than the internal bond strength of any single fiber fraction. The pulp fraction that ends in the pressure screen and in the hydrocyclone approval is very well bonded, making it impossible to determine the internal bond strength of the paper produced therefrom by the Scott bonding device. 099135961 Form No. A0101 Page 15 of 23 1003021897-0 201118215 In addition, from the end of the pressure screen and the hydrocyclone approval (PS Accreditation - HC Approved), the pulp fraction, each particle type ( That is, the width and length of epidermal cells, parenchyma cells, and fine fibers are determined by microscopic measurement (width and length are measured from micrographs). The following results were obtained: • Epidermal cells: width 11 to 21 and length 120 to 220 /zm • parenchyma cells: width 20 to 110 //m and length 40 to 300 //m • fine fibers: width 5 to 11 /zm The length is at most 0. 6 mm. Example 2. Effect of Internal Bond Strength and Other Paper Technical Characteristics of Mixed Wheat Pulp Fractions According to Example 1, the straw pulp was fractionated. The eucalyptus pulp produced by the sulphate process is refined to the degree of refinement required for typical fine paper manufacture (SR 27.5). The 10% ratio of eucalyptus cellulose is replaced by wheat straw cellulose or straw cellulose fraction and, in addition, 30% is replaced by one of these fractions (PS approved - HC approved). Therefore, at one test point, the straw cellulose was used as such, while at other test points, different pulp fractions were used. 099135961 Form No. A0101 Page 16 / Total 23 Page 1003 201118215 Table 4.

A pulp fraction composed of small components (small average particle size) and having a large ratio of the thin fibers to the epidermal cells is the most effective fraction for enhancing the internal bond strength.

On the other hand, a slight decrease of less than 1% was found in the tear resistance of the paper. In addition, the air permeability of the paper is greatly reduced. In fact, the reduction in the air permeability of the paper and the increase in its smoothness can result in a reduction in the amount of coating material or printing ink required in coating and printing, respectively, thus reducing costs. Example 3. Effect of Different Compositions of Wheat Pulp on Internal Bond Strength of Paper The amount of straw pulp fraction in the fiber mixture was varied to determine the optimum internal bond strength. The proportion of the other ingredients (other fractions) in the fiber mixture remained fixed (same as in the original pulp), and different percentages of each fraction were added to the composition under investigation. Figure 2 shows the effect of the proportion of pulp fraction on the internal bond strength of the paper, as measured by the Scott bond measurement, and it shows 099135961 in the pulp mixture. Form No. A0101 Page 18 of 23 1003021897-0 201118215 The best effect of the straw fraction. The Scott bond strength of the original straw cellulose is shown in Figure 2 as a uniform line. The abbreviated meaning of Fig. 2 is the same as that of Fig. 1. As can be seen in Figure 2, the internal bond strength of the original pulp is weaker than any other combination, i.e., the internal bond strength can be enhanced by changing the original pulp composition. The maximum internal bond strength is achieved by using a double approval, i.e., a fraction passing through a pressure screen and a hydrocyclone (PSaHCa fraction) is used. (The results from the 100% PSaHCa fraction test point were not provided because the internal bond strength of the paper made from the fraction was too strong to be determined by the device under consideration). It will be apparent to those skilled in the art that the present invention may be practiced in many different ways. The invention and its specific embodiments are therefore not limited to the examples described above, and may vary within the scope of the scope of the invention.
