Abstract
In experiments at the U. S. Forest Products Laboratory, aspen (Populus tremuloides) chips were given mild treatments with sodium hydroxide solutions at atmospheric pressure and then mechanically fiberized to produce pulps in the yield range . of 82 to 95 percent. Treatments were made with caustic solutions in concentrations of 24 and 63 grams per liter. Treating time varied from 15 minutes to 5 hours and temperature from 25° to 90° C.
