Abstract
THE PRESENT INVENTION OVERCOMES THE MALODOUR DEFICIENCY OF DELIBERATELY COAGULATED OR AUTOCOAGULATED RUBBERS FROM NATURAL LATEX DERIVED FROM HEVEA BRASILIENSIS. THE PROCESS ESSENTIALLY DEODORISE AND REODORISE THE RUBBERS RESULTING IN NATURAL RUBBERS THAT ARE ESSENTIALLY EQUIVALENTS IF NOT BETTER THAN SYNTHETIC RUBBERS IN THE AREA OF ODOUR. ESSENTIALLY THE INVENTION ACHIEVES THE REMOVAL OF HYDROLYSED PROTEINS, SULPHUR BEARING AMINO ACIDS AND THE FOUL SMELLING VOLATILE FATTY ACIDS TRAPPED IN THE AUTOCOAGULATED RUBBERS. THE DELIBERATELY COAGULATED OR AUTOCOAGULATED RUBBERS ARE TREATED WITH HYDROXIDES OF ALKALI METALS BEFORE THE DRYING PROCESS. THE TREATMENT CAN BE DONE DURING THE STORAGE OF THE LUMPS OR DURING THE FORM OF WET COMMINUTED CRUMBS OR IT CAN BE DONE IN BOTH FORMS. THE TREATED RUBBERS ARE SUBSEQUENTLY SUBJECTED TO A SPRAY OF ANTIOXIDANTS SUCH AS PHOSPHORIC OR OXALIC ACID TO MAINTAIN PLASTICITY RETENTION INDEX LEVELS. THE CRUMBS ARE FINALLY SUBJECT TO A SPRAY OF ANY COMMERCIALLY AVAILABLE ANTIBACTERIAL DETERGENT, PREFERABLY WITH AN ATTRACTIVE SMELL.
