Evaluation of agricultural residues for paper manufacture

摘要: Five agricultural residues-olive tree fellings, wheat straw, sunflower stalks, vine shoots, and cotton stalks-were evaluated for use as raw materials paper manufacture. The untreated their pulps were tested hot-water solubles, 1%-NaOH alcohol-benzene extractables, ash, holocellulose, lignin, [alpha]-cellulose, pentosans. Handsheets breaking length, stretch, burst index, tear index. results showed straw to be the most promising material. Vine shoots least promise.
