Abstract (en)
Flax structured textiles of low soiling tendency and good self-cleaning power which are not lost under mechanical loads can be achieved by the use of coatings containing at least 50 wt.% of finely divided particles unsuitable for film formation of a material (M), in which 80 wt.% of the particles are of diameter 0.5-100 micro m, and sufficient polymer binder as matrix builder. Flax structured textiles including a flax textile carrier and at least one coating on the carrier from (wt.%) at least one finely divided material (M) (50-80) in which 80 wt.% of the particles have a diameter of 0.5-100 micro m, and a matrix (20-50) including: (I) at least one fluorine-free conventional polymer binder (B); (II) at least one fluoroorganic polymer (FP) or a mixture of this with a hydrophobic wax, where the F content of component (II) is at least 1 wt.%; and (III) optionally adjuvants in amount up to 10 wt.% relative to the matrix, and the weight ratio of component (I) to component (II) is 1:2 to 100:1. Independent claims are included for: (1) a process for preparation of the textile material including application of at least one aqueous coating composition to a textile carrier and drying of the carrier, where the aqueous coating composition contains (wt.%) at least one finely divided material (50-80) in which 80 wt.% of the particles are of diameter 0.5-100 micro m and a matrix component (20-50 wt.%) including: (i) F-free polymer binder (B) in aqueous dispersion; (ii) a fluoroorganic polymer or a mixture of this with a wax , where the F-content of component (ii) is less than 1 wt. % as an aqueous dispersion; and (iii) optionally adjuvants in amount up to 10 wt.% on the matrix, where the weight ratio of binder (B) to component (ii) is 1:2 to 100:1; (2) a coating composition containing (wt.%) at least one finely divided material (50-80) in which 80% of the particles are of diameter 0.5-100 micro m, and a polymer component including: (a) at least one F-free polymer binder (B), in the form of an aqueous dispersion; (b) at least one fluoroorganic polymer (FT) or a mixture of this with a hydrophobic wax, where the F-content of component (b) is at least 1 wt.%, in the form of an aqueous dispersion; and (c) water and optionally up to 10 wt.% of binder (B), and conventional adjuvants, where the weight ratio of binder (B) to component (b) is 1:2 to 100:1; and (3) a two-component coating composition including a first aqueous coating composition containing at least one finely divided material in which 80 wt.% of the particles are of diameter 0.5-100 micro m, at least one F-free polymer binder (B) as an aqueous dispersion, water, and up 10 wt.% of adjuvants relative to binder (B).
