Abstract
The present inventions relates to a low solvent based method for the production of a microporous polymer coated fibrous fabric, comprising the steps of contacting the fabric with a composition dispersed in an aqueous medium thereby coating the fabric with the composition, and contacting the coated with a coagulation solution and drying of the fabric, crosslinking the polymer resin. Furthermore, the present invention relates to a cleaning cloth comprising a microporous polymer coating obtained by the method.
Claims12
A method for the production of a microporous polymer coated fibrous fabric, wherein the method comprises the steps of;
- a) contacting the fabric with a composition dispersed in in an aqueous medium thereby coating the fabric with the composition, wherein the composition is comprised of 1 to 20 wt % of an anionic polymer resin comprising one or more carboxylic acid groups, and 0.1 to 5 wt % of a cationic solvent, based on the total weight of the composition,
- b) contacting the coated fabric with a coagulation solution, wherein said coagulation solution is an acid solution, thereby precipitating the polymer resin on and/or in the fabric,
- c) drying of the fabric and crosslinking the polymer resin.
