Process for the manufacture of non-woven desintegru00e1vel in water, and nonwoven desintegru00e1vel in water ".A nonwoven desintegru00e1vel in water having excellent quality of dissolution in water and high moisture resistance can be obtained by a step of forming a fibrous mesh with fibers possuinOf a fibre length of 10 mm or less.A step of applying a treatment by water jet to the fibrous mesh to obtain a fibrous sheet with moisture resistance of less than 100g / 25 mm in the MD (machine direction) and CD (direction transversAl), the moisture resistance defined by the tensile strength at break of the fibrous sheet, as measured by the use of a tensile tester with a distance of 100 mm mandrel.At a speed of traction of 100 mm / min of the fibrous sheet, which is cut with 25 mm wide and 150 mm length and impregnated with water in a volume of 2.5 times the weight of the fibrous sheet.And a step of adding at least one binder selected from a group consisting of carboxymethyl cellulose, alquilcelulose,Polyvinyl alcohol and polyvinyl alcohol modified fibrous sheet. The nonwoven desintegru00e1vel in water is sufficiently thick and has an excellent effect of cleaning by wiping.
