Definitions
- the present invention relates to a water-disintegrable sheet that disperses or dissolves in water.
- Ettowipes are well known. In addition, it can be dispersed or dissolved when thrown into water such as a washing toilet, and can be washed away as it is.
- Water dispersibility typified by EttWives Water-disintegrating sheets are also well known. Here, water dispersibility and water dissolvability are synonymous, and have such properties.
- Etto vibes have high strength when used in a wet state And quick dispersibility when poured into a large amount of water. In order to achieve both the strength and the dispersibility, Japanese Patent Application Laid-Open No. H11-68999 discloses a water-insoluble canoleboxime methylose cellulose sodium.
- JP-B-48-27605 discloses a papermaking method in which an aqueous solution of metal is sprayed on wet paper made by using water-insoluble carboxymethyl cellulose. Is disclosed.
- Japanese Unexamined Patent Publication (Kokai) No. 3-167040 papermaking is carried out by mixing an alkali metal salt of water-insoluble carboxymethylcellulose with a stock.
- Japanese Patent Publication No. Hei 5 — 257972 discloses that paper made by mixing an alkali metal salt of carboxymethylcellulose with paper stock contains polyvalent zinc. Impregnated with all hydrous organic solvents.
- the carboxymethylcellulose and the salt thereof used as a binder in the prior art generally have a substitution degree (D.S.), As the pH increases, it changes from water-insoluble to swellable and becomes water-soluble. When paper is made from these carboxyl methylcellulose or its salts, and the binder is made into a sheet, if the binder has a high swelling property, Uniform mixing with the fiber becomes difficult, and if it is water-soluble, the amount of adhesion to the sheet is small, and the sheet is suitable for the binder usage. Sometimes the strength does not improve. In addition, in the process of applying a binder to the sheet obtained later by spraying, the swelling ability of canolepox methylcellulose and its salt is high. As a result, the viscosity of the aqueous solution increases, and uniform spraying becomes difficult.
- D.S. substitution degree
- the present invention presupposes the use of cellulose and cellulose or its salt and water-dispersible fiber. This is a method for producing a water dissolution sheet.
- Water-insoluble or water-insoluble carboxymethyl cellulose or a mixture of its salt and water-dispersible fiber becomes the above-mentioned hydrolytic sheet through a papermaking process.
- a base may be added to the mixture either before or after the papermaking step in the production step.
- the base is sodium carbonate.
- the production method according to the present invention includes Sheet over preparative the ⁇ et Tsu preparative follower BEST MODE FOR impregnation step you implement also Oh O 0 invention and this that is part of the Lee TOPS chemical solution
- the raw material used in the production method according to the present invention can be made into a sheet together with carboxymethinoreserulose and / or a salt thereof.
- a base is added to the binder to change it to a highly water-swellable or water-soluble one.
- Any base can be used for the base, but it is preferable to use sodium carbonate. It is preferred to use well-known papermaking techniques to sheet the mixture of fiber and binder. In addition, a wet or dry nonwoven fabric manufacturing technology, a nonwoven fabric manufacturing technology using high-pressure jet water ( ⁇ tage jet), and the like can also be used.
- the base may be added to the binder at any time before or after the papermaking process. The papermaking process itself can be considered to be included either before or after these. The present invention will be described in detail below based on examples.
- Softwood pulp for papermaking (NBKP) and carboxy Suspension and its salt were mixed with tap water, and a required amount of sodium carbonate was added to the dispersed liquid to dissolve it into paper stock. After leaving it to stand, it is paper-made with a small test paper machine, and the obtained wet paper web is dried at 110 ° C for 90 seconds using a rotating drum type drier to obtain a basis weight of 40 g. A dried sheet of Z m 2 was obtained.
- propylene glycol, calcium chloride / ion exchange water 30 / 0.5 / 69.5 (weight ratio) The sheet is impregnated with this mixture by spraying only 2.5 times its weight and left still at 20 ° C for 24 hours.
- A The specimen shreds within 100 seconds.
- Breaking strength when pulling an Etwipes specimen of width 25 mm x length 150 mm at a check interval of 100 mm and a tensile speed of 100 mm Z min was measured. If the breaking strength was at least 300 g, ⁇ Ettowipes did not become insufficient in practical use o
- the amount of sodium carbonate is 10 to 400% by weight of carboxymethylcellulose and / or its salt.
- the weight ratio of pulp to carboxymethyl cellulose and / or its salt is in the range of 98: 2 to 55:45.
- the concentration of pulp and pulp in the paper stock occupied by sorghum and / or its salt is 0.5 to 5% by weight. %
- the standing time after addition of sodium carbonate is preferably 30 minutes or more.
- t t
- CMC Carboxymethylcellulose and / or its salt
- NNKP softwood pulp
- Table 2 shows the evaluation results of the examples and comparative examples.

- a low swelling or water-insoluble ureoboxyl methylcellulose and / or a salt thereof are combined with a binder. And then mixed with the water-dispersible fibers, it is easy to attach a large amount of binder to a sheet obtained from the mixture.
- Such an inorganic material is not water-swellable or water-soluble due to the addition of a base, contributing to the improvement of the wet strength of the hydrolyzed sheet, and is used.
- the water-disintegrated paper later is put into a large amount of water, it dissolves and swells quickly, enabling rapid dispersion of the water-disintegrated sheet.
