Wasserdispergierbares Faserflächenprodukt und Verfahren zu seiner Herstellung

摘要

Provided is a water-decomposable fibrous sheet including fibers containing at least 3 % by mass of fibrillated rayon. The fibrillated rayon has a degree of beating of at most 700 cc and has primary fibers of a predetermined fiber length and microfibers extending from the primary fibers. In the fibrous sheet, the microfibers are entangled with at least either of other microfibers and other fibers therein, and the surface friction resistance of the fibrous sheet in dry, measured according to the abrasion resistance test method of JIS P-8136, is at least three rubbing cycles. <IMAGE>
