<p>The fibrous laminate (2) is hydrodynamically-consolidated. Pressed deformations are introduced into the surface of the laminate. Numerous deformations are introduced by a hot calender (6) press. They are in lines. Their depth is preferably 0.5-3 mm. Onto the layer of hydrophilic fibers of the first pre-consolidated spun-bonded fleece, a second pre-consolidated spun-bonded fleece is applied. The laminate may be consolidated subsequently. Consolidation is by water jets, followed by drying (8). One structured pressing surface is hard, and works on one side of the cloth. Another pressing surface operates on the other side of the cloth. Pressing rollers are used. An independent claim is included for the corresponding method of making the cleaning cloth.</p> |
