給障とするものである。■ Conventional technology Conventionally, water-absorbing paper manufactured using a water-absorbing polymer compound is usually produced by spraying a water-absorbing polymer compound onto one or more sheets of paper or non-woven fabric for 10 to 10,097 m''. It is manufactured by laminating one or more sheets of paper or non-woven fabric on top of this and then applying embossing to it.When using this conventional technique, two or more sheets of paper or non-woven fabric are required, and it also has a water-absorbing property. The processing speed without embossing after dispersing the polymer compound is extremely slow compared to the paper making speed.As paper, etc. are placed above and below the water-absorbing polymer compound, when water is absorbed, the water-absorbing property is high. The swelling effect of the molecular compound is inhibited, and the performance corresponding to the amount added is not exhibited, and 5.0% or more of the water-absorbing polymer compound required for the amount of water absorbed is often added in excess.These disadvantages. The purpose is to improve the supply of water-absorbing paper that internally incorporates a water-absorbing polymer compound in large quantities and at low cost.

果本発明を完成するに至った。(Q Problem to be solved by the invention In order to manufacture water-absorbing paper containing a water-absorbing polymer compound internally in large quantities and at low cost, it is necessary to mix the water-absorbing polymer compound into the paper stock.However, When a water-absorbing polymer compound is mixed with water, it absorbs water and swells due to its affinity with water and osmotic pressure.In the case of pure water, it absorbs water and swells.
Water absorption swelling occurs at an extremely large value of 1000 times. This makes papermaking extremely difficult. Also, when drying, a hair dryer requires an extremely large amount of heat. Moreover, the swollen water-absorbing polymer compound has low physical strength and is crushed in the press part of the paper machine, making it impossible to obtain an amount of water absorption commensurate with the amount of the added water-absorbing polymer compound. In addition, if the swollen water-absorbing polymer compound is made into paper at a pressure that does not crush it in the press part, it will shrink significantly in the dryer part, resulting in gaps between the pulp fibers and the water-absorbing polymer compound. It becomes easy to fall off. In order to solve this current situation, the present invention has been completed as a result of repeated research.

バッグ法によった。■Means for solving the problem, that is, the present invention, consists of mixing a water-absorbing polymer compound with an aqueous solution of calcium chloride, which is an alkaline earth metal salt, and adding the mixture to the paper stock;
Furthermore, in the wet paper state, an ammonium carbonate aqueous solution is sprinkled on the wet paper to form a paper. Since the water used in the paper manufacturing process generally requires water with low hardness, the water-absorbing polymer compound exhibits high water absorption for the water with low hardness. Therefore, when making paper by internally adding a water-absorbing polymer compound, it is necessary to suppress water absorption by mixing the water-absorbing polymer compound with an aqueous calcium chloride solution before the wire part of the paper machine. In this way, while maintaining a state in which water absorption is suppressed, the wet paper is mixed with an aqueous suspension of pulp and introduced into a wire part) to form a wet paper. The wet paper moves from the wire bar to the press part and then to the dryer part, during which an ammonium carbonate aqueous solution is sprayed, passes through a Sakushihama box, and in the solution with water, the concentration is 1/100 of pure water. further decreased to 5
% chloride power μsium in an aqueous solution is reduced to one-fifth of that of a 2% solution, and in a 10% μsium chloride solution, it is 10 times lower than that of a 2% solution.
It decreases to about 1/2. The above-mentioned action of ysium chloride was utilized to form a wet paper. After forming the wet paper, it was confirmed that by washing with water and spraying an ammonium carbonate solution, the water absorbing power of the water absorbing polymer compound was significantly recovered. That is, the water-absorbing paper that was dried by only washing with water after forming a wet paper recovered about 85% when compared with the paper that had been embossed. In addition, water-absorbing paper that has been sprayed with ammonium carbonate solution and washed with water has the same effect as ene [F]. The amount of water absorbed by the polymer compound decreases. In the case of pure water, a water-absorbing polymer compound absorbs and swells by a value of 100 to 1000 times, but it is not 2% chloride power or sia water. Note that the measurement was performed using the tea bag method.
