Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は使用時は充分な強度があり、わずかな水流に
よって容易に分散する水解性ウェットティッシュに関す
る。The present invention relates to a water-disintegratable wet tissue which has sufficient strength when used and is easily dispersed by a small flow of water.
従来よりトイレ周辺の清掃或いはおしりを拭い清める
用品として、使用後トイレに流すことができるように、
水解紙或いはこれに薬剤を担持させた洗浄用品が使用さ
れている。As a product that cleans around the toilet or wipes the ass, it can be flushed to the toilet after use.
Water-disintegrated paper or a cleaning article carrying a drug on it is used.
水解紙はトイレットペーパーに代表されるように一般
に水を含有する薬剤を含浸させると強度が著しく低下す
るので、従来含浸させる薬剤は殆ど水を含有しない非水
系薬剤に限られていた。In general, the strength of water-disintegrated paper is significantly reduced when impregnated with a water-containing chemical such as toilet paper. Therefore, the impregnated chemical has been limited to non-aqueous chemicals containing almost no water.
近年、多量の水を含有する薬剤を含浸させても清掃に
耐え得るような強度を有し、しかも使用後はトイレに流
せるような水解紙の研究がなされている。In recent years, research has been made on water-disintegrating paper that has strength enough to withstand cleaning even when impregnated with a chemical containing a large amount of water, and that can be flushed into a toilet after use.

も良好であることが例示されている。JP-A-61-296159 discloses carrageenan alone or a mixture of carrageenan and galactomannan (binder).
Discloses a water-disintegratable nonwoven fabric obtained by impregnating a water-disintegrated paper combined with an aqueous solution of salt. According to the publication, the binder is preferably contained in the nonwoven fabric in an amount of 5 to 10% by weight, and if the content is less than 5% by weight, the strength of the nonwoven fabric cannot be sufficiently obtained. It is described that if the binder needs to be long and the amount of the binder used is about 10% by weight, the basis weight of the nonwoven fabric is preferably 100 to 200 g / m 2 . In the examples of the publication, the binder amount is about 10% by weight,
It is exemplified that a wet tissue obtained by impregnating a water-disintegrable nonwoven fabric having a basis weight of 136 to 171 g / m 2 with an aqueous agent has sufficient wet strength and good water-disintegrability.

る。As is evident from these descriptions, in the case of the hydrolytic paper using carrageenan as a binder, when the binder amount is reduced, in order to obtain a wet tissue that can withstand the cleaning work, the basis weight of the nonwoven fabric is extremely increased, or the nonwoven fabric base material is used. Therefore, it is difficult to obtain a practical wet tissue economically and advantageously.

至った。The present inventors have conducted intensive studies to solve the above problems, and as a result, a hydrolyzed paper prepared using carrageenan or a mixture of carrageenan and galactomannan as a binder, adding an agent containing a specific amount of a water-soluble solvent to an aqueous solution of a potassium salt. It has been found that a wet tissue obtained by impregnation has a strength such that the hydrolyzed paper base material has a low basis weight and can withstand a cleaning operation even when the binder amount is reduced, and the present invention has been completed.

る。The water-disintegrable fiber product can be produced by any of the usual wet method and dry method. In the case of producing by these methods, after forming the web, carrageenan alone or a mixture of carrageenan and galactomannan is used as a binder in an amount of 1% by weight to 5% by weight based on the weight of pulp.
It is manufactured by spraying or applying so as to be less than. In addition, in the case of the wet method, a fiber product can be produced by mixing a binder with a pulp beating solution at the time of papermaking.

去効果が低下し、また火気に対する危険性が高まる。Examples of the potassium salt include potassium chloride, potassium sulfate, potassium dihydrogen phosphate, dipotassium monohydrogen phosphate, etc., so that the concentration of the aqueous potassium salt solution is in the range of 0.5 to 5%, preferably 0.5 to 3%. Used. When a potassium salt is used, a remarkable increase in wet strength is observed when a water-soluble solvent is used in an amount of 10% by weight or more. On the other hand, in the case of other salts such as calcium salts and ammonium salts, even if a water-soluble solvent is added, the wet strength does not increase much. When the amount of the water-soluble solvent exceeds 50% by weight, the effect of removing water-soluble dirt by wiping is reduced, and the risk of fire increases.
