Abstract:
|
Corn stalk, an agricultural waste, was valorized by the production of cellullose nanofibers (CNF), which were tested for impriving recycled paper properties. CNF from eucalyptus kraft pulp (E-CNF) was used as a reference. Addition of 0,5%wt. CNF produced from organosolv pulp (C-CNF) to recycled paper increased the tensile index by 20%, whereas the same improvement with E-CNF was achieved at 1.5%wt. Tensile index was further enhanced by increasinmg the E-CNF, whereas C-CNF achieved its maximum effect at this dose. Different recycled furnishes studied. The tensile index improvement caused by C-CNF did not depend on the proportions of old newspaper and old magazine paper used. Addition of C-CNF to recycled corrugated board fluting increased the tensile srenght, but to a slightly lower extent than in the case of recycled newsprint paper |
