Claim 1
Independent Claim
128 words
A METHOD OF MAKING A FABRIC THAT IS ABSORBENT TO LIQUID HYDROCARBONS COMPRISING THE STEPS OF IMPREGNATING A BIBULOUS SHEET OF LOOSE, UNSPUN, NATURAL COTTON FIBERS CARRYING A SUBSTANTIAL AMOUNT OF THE NATURALLY OCCURRING CUTOSE COATING, CONTAINING PECTOSE, WITH A BUTADIENEACRYLONITRILE SYNTHETIC RUBBER LATEX, APPLYING TO SAID IMPREGNATED SHEET IN THE PRESENCE OF SAID LATEX A STRONG MINERAL ACID HAVING A DISSOCIATION CONSTANT GREATER THAN ABOUT 2X10-**1 CAPABLE OF CONVERTING PECTOSE IN SAID CUTOSE COATING TO PECTIN BY REACTION THEREWITH AND CAPABLE OF COAGULATING SAID LATEX IN ADHERENT RELATION TO SAID CUTOSE COATING CONTAINING SAID PRECTIN, THE DURATION OF CONTACT WITH SAID ACID BEING SUFFICIENT TO OBTAIN THE AFORESAID RESULTS AND LESS THAN THAT WHICH RESULTS IN SUBSTANTIAL TENDERING OF SAID FIBERS, AND HEREAFTER DRYING THE IMPREGNATED SHEET.
