Description
上記課題を解決するため、請求項１に記載の発明は、
パルプ及び水溶性バインダーとしてＣＭＣを含有する実質的に水分散可能な複数プライの原紙シートに水性薬剤が含浸され、
シートの表面と裏面とのうち少なくとも何れか一方の面全体に亘って凸部のエンボスが形成された水解性シートであって、
複数プライの目付が３０〜１５０ｇｓｍであり、
前記凸部のエンボスは天面部分の面積が１０〜３０ｍｍ ２ であり、
水平に保たれた所定のタイルの上に当該水解性シートを４枚重ねて置き、さらに当該水解性シートの上に重さ１ｋｇの重りを載せ、当該水解性シートの一端より水平方向に荷重をかけ、当該水解性シートを６秒間で６０ｍｍ移動させたときの荷重を測定し、このときの最大荷重を摩擦力として測定する摩擦力測定をＭＤ方向、ＣＤ方向で各５回実施し、それぞれ各所定回数の測定値の平均を算出し、それぞれの平均値が４．５Ｎ以上であることを特徴とする。
In order to solve the above-mentioned problem, the invention described in claim 1
A substantially water-dispersible multi-ply base paper sheet containing pulp and CMC as a water-soluble binder is impregnated with an aqueous agent;
A water-decomposable sheet in which embossments of convex portions are formed over the entire surface of at least one of the front and back surfaces of the sheet,
The basis weight of the plurality of plies is 30 to 150 gsm,
The embossment of the convex portion has a top surface area of 10 to 30 mm 2 ,
Place four sheets of the water-decomposable sheet on a predetermined tile that is kept horizontally, place a weight of 1 kg on the sheet, and apply a load in the horizontal direction from one end of the sheet. Then, the load when the water-decomposable sheet is moved 60 mm in 6 seconds is measured, and the friction force measurement is performed five times each in the MD direction and the CD direction to measure the maximum load at this time as the friction force. An average of the measured values for a predetermined number of times is calculated, and each average value is 4.5 N or more.
