| titleOfInvention | Non-woven composite material and process of preparing |
| abstract | Fibrous composite sheet materials which are particularly useful as dimensionally stable backings and interliners for surface covering laminates are produced according to papermaking techniques by … … a) separately mixing together with water to form a first aqueous dispersion,… i) a cellulose fibre component comprising internally and externally fibrillated predominantly softwood pulp fibres from a refiner (30), and… ii) a filler, preferably calcium carbonate (16); … b) mixing together with water to form a second aqueous dispersion (38),… i) at soft acrylic binder resin component, and… ii) a hard acrylic binder resin component … c) mixing with water to form a third aqueous dispersion (in tank 68),… i) a non-cellulosic fibre component chosen from the group consisting of glass fibres, rock wool and other mineral fibres; … d) preparing a first combined dispersion (in drop chest 26) by combining the first aqueous dispersion prepared in step (a) with the second aqueous dispersion (38) prepared in step (b); … e) adding an excess of a cationic first flocculant (50) to the first combined dispersion prepared in step (d); … f) preparing a second combined dispersion (in machine chest 74) by combining the first combined dispersion (in drop chest 26) prepared in step (d) with the third dispersion (in tank 68) prepared in step (c); … g) adding an anionic second flocculant (86) to the second combined dispersion prepared in step (f) to adjust the electrokinetic potential of this dispersion to from about -10 millivolts to about +10 millivolts; and … h) precipitating said resin and filler components into a bonded relationship with said cellulosic and mineral fibrous components. … …<??>A size, preferably an aqueous dispersion of a hard acrylic resin, may be applied to the formed composite sheet (96) in a size press (102) following the evaporative drying step (100). |
