であった。2. Description of the Related Art Conventionally, among sanitary papers such as toilet paper, tissue paper, roll paper towel, hand paper towel, and napkin base paper, high-quality waste paper called imitation or color in toilet paper is digested in an earth pot. Fibers obtained by a method of deinking after careful selection and washing processes have been used, but in recent years, imitation and color disintegration with a pulper, then aging in an aging tower, a washing process for deinking and It is common to use cellulose fibers obtained through a screening process for removing foreign substances, and more recently, a method of chemical treatment at a low temperature with a pulper instead of a method of cooking with an earth pot has been changing. However, in these methods, the ash removal is not complete, so that the paper quality of the toilet paper becomes hard, the fluorescent dye derived from high quality paper remains, and the fine fibers increase due to disaggregation, so that the paper making process increases the paper making speed. However, there are problems such as the inability to perform the cleaning and the difficulty in recovering the white water. In the case of tissue paper, roll paper towels, napkin base paper, and the like, it has been common to use virgin valves as raw materials.

The invention disclosed in Japanese Patent Publication No. 9-1990 discloses that coarse paper pieces obtained by crushing papermaking raw materials including laminated waste paper with a pulper with a strainer are stored in an aging tower for 10 hours or more, hydrated and swelled to loosen the bond between the paper pieces and the laminate pieces. Is a method of separating and removing a laminate piece with a screen after the process.
The invention disclosed in JP-A-163385 is characterized in that laminating waste paper is disintegrated into large flakes in a pulper with the addition of alkali and then aged in an aging tower for 30 minutes to 24 hours, and then the diluted slurry is screened. It is a method. Also, the invention disclosed in Japanese Patent Application Laid-Open No. Hei 6-313285 discloses a method of crushing waste paper raw materials for milk packs and poly-laminated paper with water, caustic soda, a deinking agent and the like by a pulper and then storing them in an aging tower for 10-20 hours. This is a method for pulping waste paper of plastic-coated paper, characterized by swelling and pulping, and then dusting and refining. However, in any of these methods, it is difficult to accurately remove contaminants generated from the raw material of the plastic-coated paper, and there is a ripening step of about 10 hours in a ripening tower in a state of adding chemicals, so that when used for sanitary paper, There were problems such as difficulty in maintaining sufficient flexibility and water absorption.

145 1976 It is necessary that the contaminants measured by the “test method for foreign substances on paper and paperboard” be 40 mm 2 / m 2 or less. This is because impurities in paper using cellulose fibers taken out of the raw material of plastic-coated paper were mainly made up of dust from shredded plastics and printed matter, and could not be completely removed in the dust removal and selection processes in the pulp process. As a result, the foreign matter made the skin feel worse, but if the foreign matter was 40 mm 2 / m 2 or less, it was possible to obtain sanitary paper of sufficient quality regardless of the type of pulp. By having determined.

Toilet paper is not formulated with a wet strong resin so that it can be easily dissolved in flush toilets. Because roll paper towels and hand paper towels are used to wipe off water on the skin, they usually contain a strong wet resin and have flexibility, water absorption, odorlessness, and wet strength. It is hoped that it is.

方法。BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, sanitary papers containing high-quality cellulose fibers taken from a plastic-coated paper raw material according to the present invention will be described with reference to Examples and Comparative Examples. High-quality cellulose fibers taken out of the plastic-coated paper raw material used in the present invention were prepared from milk packs by the following method. The milk pack is introduced into the pulper with a strainer into which warm water of 50 to 90 ° C. is injected without fragmentation so that the raw material concentration becomes 5 to 30% by weight, and the operation of the pulper with the strainer is continued. After adding the alkali chemicals to the pH range where the bleaching effect of the oxidized bleach to be subsequently added is suitably exhibited,
A series of pulper treatments in which an oxidizing bleach is added so that the oxidation potential is 0.2 to 1.2 volts is performed in a short time, and then a step of removing most of the plastic by a pulper strainer treatment is carried out. UM2
After the pulp content of the mechanical pulp according to 40 1985 was reduced to 0 to 5% by weight, the slurry from which most of the plastic was removed was then washed with a heavy foreign substance removing cleaner, a coarse screen, a fine screen and a lightweight foreign substance removing cleaner. A method of extracting high-quality cellulose fibers from a plastic-coated paper raw material obtained by performing a four-stage treatment of the cleaner series of No. 1.

Created. Waste paper raw material is supplied to a pulper with a strainer together with water, caustic soda, a deinking agent (if the waste paper raw material is a milk pack, no deinking agent is used), etc., and the waste paper raw material can be sent to the next process by the pulper. The crushed paper pieces are dewatered, thrown into an aging tower, and accumulated in the tower for about 10 to 20 hours. Pulp and swollen crushed paper pieces are drawn out from the bottom of the maturation tower, and then flowed to the next dust removal and selection process to form pulp.

衛生用紙である。When the sanitary paper is tissue paper, the water absorption measured by JIS 3104 1992 "tissue paper" is determined by the JIS of tissue paper.
To reduce the standard to 8 seconds or less, see Japanese Patent Application Laid-Open No. 6-313.
In the invention disclosed in Japanese Patent Publication No. 285, in order to use the cellulose fibers taken out of a plastic-coated paper material such as a milk pack into a sanitary paper, the mixing ratio of the cellulose fibers taken out of the plastic-coated paper material such as a milk pack Must be 60% by weight or less, and in particular, in order to reduce the time to 4 seconds or less as defined in claim 3 of the present invention, the blending ratio of cellulose fibers taken out of a plastic-coated paper material such as a milk pack. On the other hand, the sanitary paper containing high-quality cellulose fibers extracted from the plastic-coated paper raw material according to the present invention has a high content of cellulose fibers extracted from the plastic-coated paper raw material such as a milk pack. 6 of
Despite being 0 to 100% by weight, it is a sanitary paper having a water absorption of 4 seconds or less and comparable to sanitary paper of 100% by weight of virgin pulp.
