Abstract

The present invention relates to a dispersible non-woven fabric, a method for producing a dispersible non-woven fabric and a wipe or tissue. The dispersible non-woven fabric comprises natural pulp fibers in an amount of from 70 to 90 wt.-% based on the total weight of the non-woven fabric and cellulosic fibers in an amount of from 10 to 30 wt.-% based on the total weight of the non-woven fabric. At least a part of the pulp fibers and of the cellulosic fibers are entangled with each other. At least 20% of the natural pulp fibers have a fiber coarseness of from 1.0 to 2.0 dtex.
