摘要:
Disclosed is a method for producing a finishing formulation for hydrophobically and/or oleophobically finishing surfaces. Said finishing formulation comprises a dispersing agent, activated particles that are dispersed in the dispersing agent and contain hydrophobic and/or oleophobic surface groups, and a binder. In the disclosed method, particles comprising hydrophobic and/or oleophobic surface groups are reduced in size in the dispersing agent in order to be activated, and the binder is added prior to or following the activation process. The obtained finishing formulation results in significantly improved physical properties of a transparent finishing while having a very good hydrophobing/oleophobing effect. Said finishing formulation is suitable for finishing all surfaces, particularly for finishing all types of fibers or fabrics.

摘要:
The invention relates to a method for applying a finishing layer to a textile carrier material. According to the inventive method, a water repellent layer or oil repellent layer, a so-called finishing layer is applied to a carrier material of the group of fibres, tissues and fabrics. The water or oil repellent finishing layer comprises at least two water or oil repellent components. A first component comprises at least one dispersing agent and a second component comprises at least one dispersed phase or a colloid. The dispersing agent and the dispersed phase are present in a gel state. The colloids of the dispersed phase are distributed in the dispersing agent in an anisotropic manner in such a way that the colloids are present in a concentrated form in the region of the finishing surface which forma a phase boundary layer between the finishing layer and the surrounding atmosphere. According to the finishing method and a first step thereof, the dispersion that is present as a colloidal solution is applied to the carrier material and is converted into a gel state in a subsequent step. The components of the dispersion are provided with an inherent capability of self-organisation. Said capability is used for obtaining the anisotropic distribution. The invention also relates to textile articles being provided with the novel water or oil repellent finishing layer. Said articles are equal or superior to products produced according to known finishing methods, with respect to the functional characteristics thereof and on the highest level. Said articles enable the chemicals which are ecologically harmful, might be harmful to health and are conventionally used to be entirely or partially replaced by novel compounds that are not in use until now.
