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清掃物品に関する。Description: TECHNICAL FIELD The present invention relates to a water-disintegratable cleaning article 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清浄用品が使用さ
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。このような水
解紙の一つとしてポリビニルアルコールとホウ酸の交差
結合を利用したものが知られている。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. As one of such hydrolyzed papers, one utilizing cross-linking between polyvinyl alcohol and boric acid is known.

を含浸させた湿潤シート物品が充分な強度があり、水解
性も良好であるとされている。For example, Japanese Patent Application Laid-Open No. 54-104963 discloses a skin cleaning cloth in which a sheet bonded with polyvinyl alcohol (binder) is impregnated with an aqueous boric acid solution. The publication states that the binder is preferably contained in an amount of 5 to 50% by weight with respect to the sheet.
It is reported that a wet sheet article in which a boric acid aqueous solution is impregnated into a sheet having a weight of about 17% by weight and a basis weight of 35 to 82 g / m 2 has sufficient strength and good water dissolvability.

必要がある。As can be seen from these descriptions, it is generally difficult to obtain a wet cleaning article that can withstand cleaning work unless the amount of the binder is considerably increased in a sheet using polyvinyl alcohol as a binder. When the amount of the binder is reduced, it is necessary to increase the basis weight of the sheet to obtain the same strength.
