Abstract
A method is provided for the application of a finishing layer to a textile support material. 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.
Claims22
A water repellent or oil repellent finishing layer applied on a support material, the layer comprising at least two components wherein a first component comprises one or more dispersants comprising at least one polar component and a second component comprises one or more apolar dispersed phases, wherein the one or more apolar dispersed phases comprises at least one colloid, and wherein the one or more dispersants and the one or more apolar dispersed phases are present in a gel state, and wherein the at least one colloid of the one or more dispersed phases is distributed in the one or more dispersants in an anisotropic manner such that the at least one colloid is concentrated in an area of an upper surface of the finishing layer.
The finishing layer according to claim l4, wherein the prepolymers comprise compounds selected from the group consisting of the following:
- a) acrylic acid dodecyl esters;
- b) methacrylic acid dodecyl esters;
- c) acrylic acid and methacrylic acid esters having a terminal tertiary butyl group;
- and d) acrylic acid and methacrylic acid esters with trimethylsilane group the methacrylic acid esters with trimethysilane group being convertible into statically modified, meltable, crosslinkable prepolymers by emulsion polymerization.
A textile article comprising a textile fibers or fabrics, and a water repellent or oil repellent finishing layer applied onto a support material wherein the finishing layer comprises at least two components wherein a first component comprises one or more dispersant(s) and a second component comprises one or more dispersed phase(s), wherein the dispersed phase comprises at least one colloid, and wherein dispersant and dispersed phase are present in a gel state, and wherein the colloids of the dispersed phase are distributed in the dispersant in an anisotropic manner such that the colloids are concentrated in the area of the upper surface of the finishing layer.
