WATER-DISINTEGRATABLE NON-WOVEN FIBROUS SHEET

摘要

A water-disintegratable non-woven sheet comprising fibers bound by a water-soluble cellulose ether can be produced by a) laying fibers to a base sheet, b) contacting the base sheet with a water-based composition comprising a water-soluble cellulose ether having a viscosity of up 500 mPa.s, measured as a 2 weight percent solution in water at 20 °C using a Haake Viscotester VT550 with a cylinder system, cup MV, at 2.55 s-1, and c) drying the sheet which comprises fibers being bound by the water-soluble cellulose ether.
