Abstract

A wet cleaning cloth for cleaning stoneware areas has a textile carrier, with individual unbundled elastic fibres in a range from 1,000 to 2,000 per square centimeter extend from one side of said textile carrier. Said individual fibres are arranged at a certain distance from each other and extend with a length range of 2 to 12 mm from said carrier, said fibres having a free end with a sharp edge.

Claims

1. Wet cleaning cloth for cleaning stoneware areas having pores in its surface, said cloth comprises:

a textile carrier having individual unbundled elastic fibers extending from one side of said textile carrier,

said individual fibers are arranged at a distance from each other for avoiding bunching of the fibers, the number of said fibers per square centimeter ranges from 1,000 to 2,600,

said fibers extend from said carrier with a length ranging from 2 to 12 mm, and

said fibers have free ends with a sharp edge resulting from a cutting treatment for cutting said fibers to said length.

2. Wet cleaning cloth of claim 1, wherein the fiber length is in the range between 4 to 10 mm.

3. Wet cleaning cloth of claim 1, wherein the fiber length is approximately 6 mm.

4. Wet cleaning cloth of claim 1, wherein the number of fibers ranges from 1,400 to 2,200 per square centimeter.

5. Wet cleaning cloth of claim 1, wherein approximately 1,800 fibers per square centimeter are present.

6. Wet cleaning cloth of claim 1, wherein the fibers are made of polyester.

7. Wet cleaning cloth of claim 1, wherein the textile carrier is made of a polyester material.

8. Wet cleaning cloth of claim 1, wherein a terminal surface resulting from said cutting treatment runs at a slanting angle with respect to the longitudinal axis of the fiber.

9. Wet cleaning cloth of claim 1, wherein the fibers are circular in cross-section.

10. Wet cleaning cloth of claim 1, wherein the fibers, are pre-bent in an undulating form.
