Depithing of Helianthus Tuberosus was performed for one and five minutes in a Morden Slush Maker at 115°C and 7% consistency. The pith and fines were removed, leaving the woody chips. The chips were pulped using sodium hydroxide in a bomb digestor at a five to one liquor to wood ratio using 20% active alkali for one hour at 170°C. The resulting chips were fiberized and handsheets were made according to Noble and Wood procedures. The handsheets were tested and reported.
The resulting fibers show little promise for use in papers requiring high tensile or tear.
