A method is proposed for the application of a finishing layer to a textile support material. By means of the novel method, a water repellent or oil repellent layer, a so-called finishing layer, is applied to a textile support material selected from the group of fibers, tissues, and fabrics. The water repellent or oil repellent finishing layer comprises at least two water repellent or oil repellent components wherein a first component comprises one or more dispersants and a second component comprises one or more dispersed phases or colloids, and wherein the dispersant and the dispersed phase are present in the gel state. The colloids of the dispersed phase are distributed in the dispersant in an anisotropic manner so that the colloids are concentrated in the region of the upper surface of the finishing layer forming an interface between the finishing layer an the surrounding atmosphere. In a first step of the finishing method the dispersion in a sol state is applied to the support material, and in a subsequent step is transformed into the gel state. The components of the dispersion have an inherent capability to self-organize with is utilized to achieve an anisotropic distribution. Furthermore, textile articles are proposed having the novel water repellent or oil repellent finishing layer which are equal on a high level or even superior with respect to their functional properties to products prepared according to known finishing methods and at the same time allow a complete or partial substitution of the health and environmentally hazardous standard chemicals employed nowadays by novel compounds which have not been used to date.
