There is provided a treatment agent applicable to a recording surface of a recording medium which is recording paper or fabric. The treatment agent contains: a non-cationic sizing agent; and at least one cationic substance which is selected from the group consisting of: a cationic polymer capable of forming a flexible film in a case that the cationic polymer is dried, a cationic surfactant, a polyvalent metal salt and a polyvalent metal ion.

The application relates to the production of a soiled fabric, and more particularly to a method of manufacturing a standard carbon black soiled fabric for performance testing of washing machines. Water is adopted herein as the solvent to prepare a soil, which renders this method safe, environmentally friendly and economical. Moreover, this method introduces a fully-automatic continuous rolling-suction tentering and setting machine to control the pressure of the padder, the drying temperature, the air volume of the fan and the speed of chains, which reduces the manual intervention, achieving a highly-automatic printing and dyeing process. The reflectivity at four points on both sides of the standard carbon black soiled fabric according to the invention is 95% or more.

A whitening composition for fabric, in particular, unbleached cellulosic fiber-containing fabric is described. The composition includes a blue dye, a violet dye; and, optionally, a thickening agent; wherein the composition is free of bleaching agents and optical brighteners. A method of whitening a fabric using whitening compositions is also disclosed.

A dye-releasing product for dyeing of or for refreshing of dyeing in textile materials is provided. The dye-releasing product includes a flat, cloth-like carrier material, and at least one coating applied onto the carrier material. At least one indigoid dye in its oxidized form is encompassed by the coating. The coating contains at least one binding agent for the at least one indigoid dye such that the at least one indigoid dye is released in an aqueous solution with a temperature equal to or greater than 20 C. that is, the coating is soluble, at least in part from the flat, cloth-like carrier material, which is added to the textile material to be dyed or whose dyeing is to be refreshed in a washing process.

The disclosure relates to a coating composition that can be applied to a substrate, especially a cellulose substrate. A layer of the coating composition applied to the substrate provides an excellent ink receptive layer and can be used as a coating on paper. The disclosure also relates to aqueous compositions and method for applying the layer of the coating composition onto the substrate.
