Competition issues with food industry have recently boosted the exploration of alternative solutions capable replacing starch in papermaking to a certain extent. Covalent grafting quaternary ammonium groups onto LignoBoost® Eucalyptus kraft lignin has shown promise this regard as cationic products feature excellent water solubility across entire pH scale. Considering these suitable properties, ...

Abstract In this investigation, softwood pulp and bleached wheat straw were used as raw materials, Calcium Sulfate Whiskers (CSW) fillers. Based on the structural properties characteristics of CSW, printing paper with such whiteness, opacity, pH value, uniformity, Z-direction tensile strength surface strength, analyzed. The results showed that CSW has low solubility, high retention fiber-like a...

the effect of bleaching with sodium hypochlorite, as one of the most important parameters in obtaining optimal alpha cellulose pulp from cotton linter was studied. in this respect, unbleached cotton linter pulp was prepared from parchin chemical industry co., bleached by hea sequence in ph=9, 11 and 13; and then its chemical structures properties such as alpha cellulose, degree of polymerizatio...

This study aims to understand the effect of micro- and nanofibrillated cellulose (MNFC) on tensile index, softness, water absorbency tissue paper. MNFC was produced from four different fiber sources. The results show that acts as an effective strength enhancer at expense a reduced softness. impact source manufacturing cost trade-off with performance also investigated. MNFCs southern bleached ha...

• Softwood Kraft pulp was successfully activated by mechano-enzymatic treatments. The activation endoglucanase TrCel45A surpassed that LPMO TrAA9A. Dissolution time decreased with increasing fines, fibrillation and porosity. combination of TrAA9A halved the original dissolution time. manufacturing man-made cellulose fibers starts wood fibers. Pulps can dissolve at different rates leave amounts ...

Abstract The energy demand to produce cellulose nanofibrils, CNFs, is high and additionally the cost of starting material, pulp, substantial as purity dissolving pulp generally used. Pulps aimed for board paper are produced at higher yield they contain hemicelluloses and, in case unbleached lignin, would be a more economical material CNFs. It interest understand how presence hemicellulose ligni...

HYDROGEN PEROXIDE HAS ALWAYS been a technologically attractive oxidant to the pulp and paper industry, with its significance becoming increasingly important as environmental regulations become more stringent. Beyond its ease of handling and application, hydrogen peroxide is also a versatile and benign compound whose decomposition products are water and oxygen. Among its major drawbacks are its ...
