  • Patent number: 10406565
    Abstract: A cleaning cloth has a microfiber composite fleece material in which a first and a second fiber component are arranged in the form of alternating layers, wherein at least one first layer A has the first fiber component in the form of composite filaments which are melt-spun and deposited into a fleece and which are at least partially split into elementary filaments having an average titer of less than 0.1 dtex, preferably between 0.03 dtex and 0.06 dtex, and solidified, and wherein at least one layer B is arranged on the first layer A, wherein the layer B has the second fiber component in the form of fibers deposited into a fleece and solidified and having an average titer of 0.1 to 3 dtex, at least one second layer A is arranged on the layer B.

  • Patent number: 6706652
    Abstract: A cleaning cloth is described made of a microfilament nonwoven weighing from 30 g/m2 to 500 g/m2, the nonwoven being made from melt-spun, stretched continuous multicomponent filaments having a titer of 1.5 to 5 dtex, which are immediately laid down to form a nonwoven, and the continuous multicomponent filaments, optionally after pre-bonding, being split at least to 80% to form continuous micro-filaments having a titer of 0.05 to 1.0 dtex and bonded.

  • Publication number: 20030204926
    Abstract: An operating handle (1) for devices, particularly for cleaning devices, such as wiping devices, mops, brooms, or the like. The operating handle (1) has at least a first and a second tubular handle element (2, 2′) which are able to be joined to one another. The tubular handle elements (2, 2′) form a hollow space (5). A connecting link (4, 4′) is provided for connecting the first and the second handle element (2, 2′). The connecting link (4, 4′) extends at least partially into the hollow space (5) formed by the handle elements (2, 2′). A first connecting segment (6) and a second connecting segment (7) are provided. The first connecting segment (6) is designed to connect to the first handle element (2), and the second connecting segment (7) is designed to connect to the second handle element (2′).

  • Patent number: 6543082
    Abstract: A holder for securing mop at the end of a handle, in which a plurality of relatively moveable, absorbent strips made of a textile material are affixed as a result of being clamped between a headpiece and a plate, essentially at right angles to the longitudinal axis of the handle. In the region where the strips are fastened, the holder has a surface area having a length greater than its width, and boundary edges of which are curved to form two corners, without changing the direction of the curvature.
