ABSTRACT:
A process is described for obtaining finishing effects on textile material consisting, at least partially, of cellulose fibers, without seriously reducing the tensile strength, tearing strength or wearing strength of the fibers. A finishing agent, capable of cross-linking with the hydroxy groups of the cellulose fibers, in a solution or emulsion containing a mixture of water and at least one organic solvent, such as low aliphatic ketones, aliphatic chlorinated hydrocarbons or low aliphatic esters, is applied to the textile material. The stability of the mixture is controlled by a salting-in or salting-out effect so as to induce a phase separation between aqueous and solvent phase, this effect being induced by the use of neutral salts, acid salts, potentially acid salts, organic acids, synthetic resins or reactants. The finishing agent is concentrated in the aqueous phase in the interior of the individual fibers while the surface zones retain the good surface properties of the starting material. Subsequently the textile material is heated to produce a wash-resistant fixation in the textile material.
