出てきた。2. Description of the Related Art As a means of solving the problem of the natural environment, we reflect on the fact that paper, which has been used in large quantities, has been made of wood pulp. The movement to use it has been increasing. There is a large number of people who pulverize bagasse (sugar milled cake), which is easily and massively collected as a raw material, mix it in wood pulp in a small amount, and sell it as non-wood paper on the market. However, recently, some people have requested to use 100% non-wood pulp high quality paper if it is supplied.

（クラフトパルプ）をつなぎのパルプとして少量配合し
なければ上質紙は抄造できなかった。However, it has heretofore been considered that 100% bagasse pulp paper is too weak for general use. Bagasse has a lower lignin content than wood and a high content of cellulose and hemicellulose, so it is easy to pulpate, and it is likely that high-quality pulp will be obtained in high yield.
Defects have been pointed out, such as low yield, poor strength, and particularly poor tear strength. For this reason, KP of conifers with high strength and large fiber length is usually used for a large amount of bagasse pulp.
Fine paper could not be made unless a small amount of (kraft pulp) was blended as a connecting pulp.

諸強度が大きく向上することでも理解できる。[0004] If paper with 100% non-wood pulp is to be produced, the only option is to at least drastically improve the strength of the bagasse pulp, or to also convert the tether pulp to non-wood pulp and allow for its large supply. Was.
Bagasse pulp has low strength compared to the composition of its raw materials because sugar millet fibers are generally short in nature, and furthermore, during sugar production, the fibers are further destroyed by a strong mechanical shock, and even during cooking, This is probably due to chemical damage at high temperatures. Particularly, the damage by the AP cooking chemical (aqueous solution of sodium hydroxide alone) is severe, and the strength of the obtained pulp is not excellent. These drawbacks are that pulp obtained by cooking with KP cooking liquor (a mixture of sodium hydroxide and sodium sulfide) or PA cooking liquor (adding a cooking aid such as a stabilizer to an alkaline solution of hydrogen peroxide) It can also be understood that various strengths other than the tear strength are greatly improved.

な産業用紙を製造してきた。[0005] In any case, bagasse pulp alone is insufficient in strength. As the beating process proceeds, the breaking length and specific burst strength increase somewhat, but the freeness decreases, the suitability for papermaking decreases, the tear strength further decreases, and the resulting paper increases in density and becomes crisp and opaque. And the printability and writing characteristics were reduced, and high quality paper could not be produced. Thus, high-quality paper such as printing paper and writing paper and industrial paper such as paperboard have been manufactured by blending 10-20% of softwood KP with bagasse pulp as a main raw material.

る。[0006] In the south, both wood and non-wood generally have short fiber lengths, and it is not required to have long fibers other than hemp. However, hemp is precious because it is scarce in resources and has applications in ropes and woven fabrics. Pulp made from hemp is extremely valuable because it is used as a special high-grade pulp used in the production of special papers and the like, and it has been considered that it cannot be supplied in large quantities as pulp for the production of inexpensive general paper.
Hemp pulp has a long fiber, flax pulp has a particularly long fiber,
If beating is performed to obtain a strong, high-density paper, the fibers will be twisted and the fibers will stick together, creating so-called lumps, impairing the aesthetics of the paper and significantly lowering its commercial value.

の成功例や、新たな企画は報告がなかった。[0007] However, flax is too long in fiber and has a lot of dust, and it is difficult to use pulping in the conventional method, so that it can be collected in a large amount. But,
Flax contains a lot of non-fibrous impurities and dust, such as plant skin, and it is not easy to separate and remove unpulped products and remove dust when pulping by the conventional cooking method. Even so, the obtained paper is dirty and the commercial value is very poor, so there have been no reports of successful examples of commercial production of high-quality paper such as printing paper, and no new projects.

提供する。The present invention uses bagasse pulp obtained by pulping a large amount of by-product bagasse in a sugar mill by a conventional method or, preferably, a PA method, and using the obtained bagasse pulp as a main raw material. As main auxiliary raw materials, there are many impurities and dust, and it is difficult to digest,
Conventionally, flax dust that has been slightly used only for special purposes, such as the production of cigarette wrapping paper and India paper, is beaten with a beater after over-pulping treatment, and is processed by the PA method. A cooked product without cooked material is obtained, and is beaten in a free state at a low concentration to reduce the length of fibers, and then dust is removed to obtain a tethered pulp which is easy to handle. The PA method pulp and bagasse pulp made of flax dust can be suppressed in twist if lightly beaten lightly and have good strength without impairing aesthetic appearance.
0% non-wood pulp fine paper is obtained. In addition, if desired, straw pulp and / or cotton pulp may be added in addition to the PA pulp of flax dust to provide excellent surface smoothness and / or texture.
A high quality paper made of 100% non-wood pulp and a method for producing the same are provided.

Since the bagasse pulp obtained by the method or the PA method has a higher strength than that obtained by the AP method, the amount of tethered pulp added is small.

〜９２％の高白色度の晒パルプが得られる。Pulping bagasse by the PA method rather than pulping the bagasse by the KP method is because unbleached pulp has a whiteness similar to that of the semi-bleached pulp of the KP method pulp, bleach-free chlorination or bleaching. Since low chlorination is easy, it is desirable to address global environmental issues. Bagasse pulping by the PA method is performed by a conventional method. Its pulping conditions take wide, preferably at normal caustic and alkali carbonate, 15% to 30% in terms of Na 2 O as a total alkali, 65-85% caustic degree, hydrogen peroxide as the H 2 O 2 2 ~

%, Magnesium hydroxide or the like as a magnesium compound, and 0.05 to 0.2% as MgO to prepare a cooking chemical. Both liquid-phase cooking and gas-phase cooking are possible, but the gas-phase cooking in the PA method has a liquid ratio of 1.5 to 3.0 without uneven boiling.
L / kg, which is extremely small, and can significantly reduce the energy for pulping of pulp and concentration of pulp waste liquid, which is preferable in reducing carbon dioxide generation and preventing global warming. The digestion has a maximum temperature of 110-130 ° C, and the holding time is 3
0-120 minutes. The resulting unbleached pulp has an extremely low Kappa number of 3 to 7, and an extremely high Hunter whiteness of 45 to 60%. Unbleached pulp can be bleached by treating with a Pa chemical (alkali hydrogen peroxide solution) or with a Pa chemical in the presence of oxygen to obtain a semi-bleached pulp with high whiteness. Thus, chlorine bleaching can be achieved by chlorine dioxide bleaching at the subsequent stage, and chlorine-free bleaching can be achieved by ozone bleaching.
A bleached pulp of -92% high brightness is obtained.

用いる。[0012] The flax flax is not used as a raw material for the PA method pulp of flax. Ordinary flax has uses such as yarn and fabric, and is expensive and difficult to collect in large quantities as a pulp raw material. Conventionally, flax, which has not been used as a raw material for ordinary paper, has been made into a short fiber by free beating at a low concentration after digestion with a cooking chemical of the PA method or a chemical obtained by adding oxalate to this if desired. The pulp is not as strong as specialty paper pulp, but has the same strength and ease of handling as bleached KP of softwood. Contaminants and dust in the raw material are eliminated by PA digestion and selection, and the raw material pulp can be used for bagasse paper production. As for the cooking chemical of the flax PA method, the bagasse cooking conditions and the composition of the chemical can be applied mutatis mutandis, but the amount of alkali used is somewhat higher at 18 to 35%, and the cooking temperature is 135 which is slightly higher than the above-mentioned bagasse cooking temperature. ~ 15
5 ° C. Jordan or disc refiner or the like can be used as the apparatus used for the free beating, and flax pulp is operated at a raw material concentration of 1 to 7%, preferably 2 to 5% to shorten the fiber, and CSF 200 to 200% at the time of mixed papermaking. 600m

る。[0013] By blending straw pulp and cotton pulp, it has become possible to provide a high quality paper with 100% non-wood pulp, which is more favorable in writability, printability and texture, and a method for producing the same. In particular, the blending of straw pulp contributes to the improvement of printability, and the blending of cotton pulp contributes to the supply of high quality paper having excellent writability and a luxurious feel. Both of them have a small amount of addition, so that pulp by the conventional method may be used, but pulp by the PA method is more preferable from the viewpoint of quality improvement. For the pulping conditions by the PA method, bagasse pulping conditions can be applied to straw pulp, and flax pulping conditions can be applied to cotton pulp.

工程を管理することが望ましい。In the papermaking, the compounding ratio of bagasse pulp which is inexpensive and can be supplied in large quantities is made high, and is 70 to 95%, preferably 85 to 90%. The use of high-strength bagasse pulp makes it possible to reduce the amount of tethered pulp used. It is preferable to beat each separately, rather than to mix all the pulp at the same time, to obtain bagasse paper with high strength. Bagasse has a CSF of 350 to 6 because even if it is strongly beaten, the strength is not increased so much that the freeness is lowered and a trouble in the paper making process is easily caused.
It is desirable to stop at 50 mL, preferably 450-550 mL of CSF. The flax dust is relatively abundant as an unused resource, and the pulp obtained by the PA method is strong, so that twisting due to mild beating can be suppressed and CSF 400
It is desirable to control the process to ~ 600 mL, preferably 450-550 mL CSF. Straw pulp improves the surface smoothness of the paper and contributes to the improvement of printability. However, since reducing the beating to a small extent can prevent the drainage from dropping in the papermaking process, CSF is 400 to 600 mL, preferably CSF.
It is desirable to control the process to 450-550 mL. Cotton pulp contributes to improving the texture of bagasse paper for printing, and is good for giving a sense of quality. However, if the beating is not advanced, the surface of the paper may be extremely damaged.
It is desirable to control the process to 500 mL, preferably 200-300 mL of CSF.

The sizing agent gives the paper an appropriate level of water resistance and prevents bleeding.There is a conventional typical rosin size, but since the end of the sizing process is stopped with a weak acid, the paper gradually deteriorates. Unbearable for a century of preservation. Neutral size is preferred for long term storage of documents. The neutral sizing agent can be selected from commonly used ones such as alkyl ketene dimer and the like, and a surface size such as CMC or glue size can also be used.

Particularly, pulp such as bagasse and rice straw containing a large amount of pentosan in the pulp used is beaten to increase the density of the paper and to increase the crispness and decrease the opacity. Becomes intense. According to the present invention, the blending of flax pulp does not require excessive beating, and the blending of cotton pulp increases opacity and reduces the need for fillers. If added, fillers such as China clay, talc, titanium white, etc. are effective.
