Claim 1
Independent Claim
132 words
A PROCESS FOR PREPARING RIGID, SHAPED, FELTED, FIBROUS COMBUSTIBLE PRODUCT HAVING HIGH TENSILE STRENGTH COMPRISING THE STEPS OF 8A) TREATING A HOMOGENEOUS AQUEOUS MIXTURE CONSISTING ESSENTIALLY OF AN AQUEOUS SUSPENSION OF 1 TO ABOUT 5 PARTS OF NITROCELLULOSE AND ABOUT 1 TO 2 PARTS OF CELLULOSE FIBERS, AND 1 PART OF RESIN BINDER CONSISTING ESSENTIALLY OF AN ALKALINE REACTION PRODUCT OF PHENOL AND FORMALDEHYDE CONTROLLED TO YIELD A RESIN WITH A VISCOSITY IN THE RANGE FROM ABOUT 200 TO 400 CPS. AND ABOUT 250-400% WATER TOLERANCE AT ABOUT 5060% SOLIDS CONTENT, WITH AN AMOUNT OF HALOGEN SALT OF A TRIVALENT METAL SUFFICIENT TO PRECIPITATE SAID RESIN BINDER, (B) REMOVING EXCESS WATER FFROM SAID MIXTURE TO DEPOSIT A FIBROUS MASS, (C) SHAPING SAID MASS, AND (D) HEATING SAID MASS AT 120-180*F. UNTIL DRY.
