Abstract

See full text

A method of extracting hemp fibers from decorticated hemp bast skin involves pre-treating the decorticated hemp bast skin with an aqueous solution containing di-sodium citrate, tri-sodium citrate or a mixture thereof having a pH of from about 6-13 at temperature of about 90° C. or less; and subsequently treating recovered fiber with a enzyme. Determining the extent of completion of a plant fiber degumming process involves treating degummed fiber with a recombinant pectinase expressed in an organism that produces neither cellulose nor xylanase, to release reducing sugar from any residua pectin on the degummed fiber, and, quantifying the released reducing sugar.
