Sponge cloth based on cellulose comprises: an internal reinforcement of a network and/or a lattice; fibers, which are uniformly distributed in the sponge cloth; and/or a permanent-softening polymer, which is not washable with water. An independent claim is also included for producing the sponge cloth, comprising: mixing viscose, a pore-forming agent, fibers and/or hydrophilic softening polymer into a homogeneous sponge cloth-raw material to be mixed; molding the sponge cloth-raw material into a layer; placing the network and/or the lattice on the layer; applying an additional layer of the sponge cloth-raw material on the network and/or the lattice; removing the pore-forming agent, and coagulating and regenerating the cellulose from viscose in alkaline or acid baths; washing the obtained sponge cloth; and optionally wetting the sponge cloth. |
