a 0 20 u2033 slotted screen the accepts that passed though the screen were saved for use in making product and testing fiber and product properties reported in this application harvested soy stalk was obtained in bale form and processed through a hay grinder with a 3 inch minus screen to provide chopped stalk fifty kilograms of chopped stalk was placed in a digester at 10 consistency and 10 naoh caustic by dry fiber weight the mixture was then cooked at 190 degrees fahrenheit for one hour the digested fiber slurry was then refined using a 12 u2033 sprout waldron double disc refiner set at minimum plate clearance the refined fiber was then dewatered to about 25 solids using a screw press the dewatered fiber was then diluted with water to 4 consistency the product was then pumped through a pressure screen using a 0 20 u2033 slotted screen the accepts that passed though the screen were saved for use in making product and testing fiber and product properties reported in this application laboratory hand sheets were prepared from the finished fibers of examples 1 and 2 as follows the wet slurries of wheat straw fiber soy stalk fiber and mixtures of both fibers were weighed in a beaker and transferred to a disintegrator and processed for 500 revolutions the slurry was then transferred to a hand sheet mold and wet laid into an 8 u2033 u00d7 8 u2033 sheet at 140 grams per square meter basis weight the sheets were then dried at 300 degrees fahrenheit and then pressed for one minute between polished steel plates the following hand sheet compositions were prepared 1 100 wheat straw fiber 2 100 soy stalk fiber 3 95 wheat fiber 5 soy fiber 4 75.
