ABSTRACT:
The present invention, in certain embodiments, discloses a method for treating cellulose fibers comprising treating cellulose fibers with an acidic medium, and applying an adhesive composition to the cellulose fibers, the adhesive composition including polyvinyl alcohol cooked without addition of an acidic substance. The present invention, in certain embodiments, discloses a method for spraying with a spray nozzle an insulation composition onto a substrate, the method including introducing cellulose fibers under pressure through a first hose into the spray nozzle, the cellulose fibers treated with an acidic medium, introducing an adhesive composition under pressure through a second hose into the spray nozzle, the adhesive composition comprising polyvinyl alcohol cooked without an acidic medium, and spraying from the spray nozzle the treated cellulose fibers and adhesive composition onto the substrate.
