Self-standing and flexible regenerated cellulose membranes were fabricated by using a facile ZnCl2/CaCl2/cellulose dissolution system. The filtration experiments of the membranes were conducted by using methyl orange and Congo red as water contaminations. To improve the selectivity and stability, the crosslinkers of glutaraldehyde and polyvinyl alcohol were introduced to the membrane network. The...
The objectives of this work were to investigate the effect of the degree of fibrillation and addition method of cellulose nanofibrils (CNFs) into the wet end of the papermaking process on the drainage, filler retention, strength and optical properties of handsheets. CNFs were produced with the grinding method, and the degree of fibrillation was manipulated by varying the passing number through the...
