Paper with improved air permeability has the advantage of improved drying when used, for example, in gypsum board or wallpaper,
It is also highly useful as a packaging paper for fresh vegetables. Paper with improved water absorption has advantages such as improved adhesion when used on gypsum board, for example. On the other hand, paper provided with anti-slip properties is effective in making it difficult for the paper containers to slip when they are stacked and transported in multiple stages.

Description of the Related Art As a method for imparting air permeability to paper, air permeability improving agents are not generally used, and the air permeability is exclusively changed by physically changing the structure of the paper or by making small holes in the paper. It is an improvement. However, the method of improving the air permeability by changing the physical structure of paper or forming small holes has a drawback that the manufacturing cost is high and the strength of paper is not sufficiently obtained. there were. As a method of imparting water absorption to paper,
There is the addition of a surfactant-based hygroscopicity improver, but there is a problem that the effect is not sufficient unless a large amount is added.
On the other hand, as a method for imparting anti-slip properties, a method is generally applied in which a surface of the finished paper is coated with an anti-slip agent composed of a copolymer of styrene and an acrylic ester, or fine colloidal silicon oxide. In the case of applying the anti-slip agent to the surface of the paper as described above, the adhesion between the anti-slip agent and the surface of the paper is not sufficient and the paper easily comes off, and for the purpose of suppressing this omission, a starch The addition of surface enhancers was necessary.

By adding the rice husks of No. 2 to pulp, preferably by adding 2 to 50% by weight to the pulp,
It has been found that the object can be achieved, and the present invention has been completed based on this finding.

により任意にそろえて用いることが出来る。The rice husk used in the present invention has 63 husks.
It is finely pulverized to ˜2000 μm, and the finely pulverizing method is not limited. For example, the rice husk is marketed under the trade name “Sumiselco” in which the rice husk is ground into fine particles. Things correspond. The classification of the particle size of the powder or granular material in the industrial field is generally performed as a method that can easily separate the particles that pass through the mesh and the particles that do not pass by using a sieve. Regarding the mesh opening of the sieve, the standard sieve is defined in Japanese Industrial Standard JIS Z 8801-1987, and the grain size of the rice husk of the rice family grain used in the present invention is 63 to 2000 μm, and the standard sieve / mesh sieve is 63 μm, And the standard sieve / mesh sieve of 2 mm can be used to classify the minimum particle size and the maximum particle size, respectively, and the particle size between them can be arbitrarily adjusted by using a standard sieve having a desired opening. .

Although the particle size is 3 to 2000 μm, if the particle size is less than 63 μm, the structure of the obtained paper becomes too dense and the effect on air permeability and water absorbency becomes small, and the effect on slip resistance is also small. On the other hand, particles having a particle size of more than 2000 μm are effective for improving the air permeability, water absorption and anti-slip properties which are the objects of the present invention, but are not preferable in terms of general paper performance and appearance. The crushed rice husk of Gramineae grains is preferably 2 to 50% by weight, more preferably 5% by weight, based on the pulp.
˜15% by weight. If it is less than 2% by weight, the desired effect is not sufficient, and if it is more than 50% by weight, not only is it economically disadvantageous, but the paper quality, particularly the strength of the paper, is not sufficient, and the appearance is also unfavorable.

徴を有している。An attempt to finely pulverize the rice husks of cereals as a composition for paper has been described in, for example, Japanese Patent Application Laid-Open No. 3-152298, in which paper is filled with rice husk fine powder of 60 μm or less. According to this publication, the purpose is as a general filler for paper, and 20 to 40 μm is the best particle size. Since the intent of the present invention is to improve the air permeability, water absorbency, and slip resistance of paper, it is preferable that the rice husk used is larger than the particle size described in the publication, and since it is a paper used for industrial purposes, Even if it appears yellow to yellowish brown in appearance, it does not cause a big obstacle, and refines finely pulverized rice husks.
It has the feature that it can be used as it is without bleaching.

のではない。When the method of the present invention is applied, the papermaking method is not particularly limited. The addition of the finely pulverized rice husk processed product to the pulp in the present invention is not limited at which time of the papermaking process, but if the uniform mixing with the pulp is considered, the beginning of the process is preferable. For example, it can be said that a machine chest after the beating step is suitable. When adding this finely pulverized rice husk processed product to the pulp, it is possible to add the solid as it is into the pulp slurry, but if considering uniform mixing with the pulp, the finely pulverized rice husk processed product is It can be said that it is more preferable to disperse in water in advance, further add a dispersant if necessary, and put this in the pulp slurry.
It should be noted that, in the step after mixing the finely pulverized rice husks with pulp, it is often possible to use a usual paper-strengthening agent, retention aid, etc. as an additive aid for the paper stock together with good results. The addition of seed additives does not limit the invention in any way.
