Abstract (en)
[origin: EP2108734A1] In a method for finishing fibers and textile sheets by fixing absorbent microspheres (a) using a film-forming polymeric binder (b), an aqueous dispersion of (a) is produced using 6-24C fatty acid alkali(ne earth) metal soap dispersant; the textile is introduced into the dispersion; the pH of the aqueous liquor is slowly reduced by adding acid to convert the soap into the corresponding fatty acid; and (b) is added. A method for finishing fibers and textile sheets, by fixing absorbent microspheres (a) on the textile surface using a film-forming polymeric binder (b), involves: (1) forming an aqueous dispersion of the microspheres (a) using 6-24C fatty acid alkali(ne earth) metal soaps (optionally formed in situ from the acid and hydroxide) as dispersant; (2) introducing the textile into the dispersion (optionally under dilution with water); (3) slowly reducing the pH of the aqueous liquor by adding (in)organic acid, so that the soap is converted into the corresponding acid; and (4) adding the binder (b), which is exhausted onto the (a)-charged textile in the acidic pH region.
