Increased bonding of recovered fibres with cationic flours and enzyme hydrolysed sugarbeet pulp [Full subscriber]

Cationic flours (CF, wheat origin) increased both tensile and burst index plus internal bond strength of handsheets prepared from recovered fibres (RF, from recycled papers and cardboards) without or with 10% fibrous residue from enzymatic hydrolysis of sugarbeet pulp (EHSBP). Strength properties of handsheets from RF were higher with the combination of CF and EHSBP than with CF alone. CF increased bending resistance and reduced air permeation resistance of handsheets. Converse was true for EHSP. CF partially checked the negative influence of EHSBP on drainage time and water retention value of RF suspensions when both were combined. COD and BOD5…
