CLEANING CLOTH |
摘要 |
<p>A cleaning cloth for domestic or industrial use comprising a soft non-woven elastic needled fleece material with a relief pattern of scouring. strips protruding from the working surface, the strips having a height to width ratio of about 0.2 to 0.4 with the height being up to about 0.5 times the thickness of the needled fleece. A continuous layer of open cell latex foam is placed on the back surface of the fleece material and extends into it for a distance of about 10% to about 40% of the thickness of the fleece. The length of each strip is about 3 to 8 times its width and is separated by a gap from its adjacent strips. The material of. the strips may have a cellular structure of which the pore volume is about 10% to 50% of the total volume of the material and the strips may be arranged in a regular pattern on the fleece. The continuous layer on the back surface may extend above the surface for substantially the same distance as it extends into the fleece material. Such a cloth has very good scouring, cleaning and polishing properties with particularly high liquid absorption capability.</p> |
