The demand of tissue papers is increasing with the population increase. This will definitely increase need wood fibers as main raw material. However, due to shortages, there have been many attempts use non- substitutes for papermaking. In Indonesia, corn production has gradually increased last 5 years, hence it also an impact on raising in amount husk waste. Corn a high cellulose content which ...

Specific and strong cellulose-binding characteristics were utilized for promoting retention of additives in contaminated papermaking systems. Cellulose-binding domain (CBD) of cellulase derived from Trichoderma viride was separated by digestion with papain, and then introduced into anionic polyacrylamide (A-PAM) through a condensation reaction using water-soluble carbodiimide. The CBD-modified ...

Optimizing the desired properties for stretch monolayer separators used in Lithium-ion batteries has been a challenge. In the present study a cellulose nanofiber/PET nonwoven composite separator is successfully fabricated, using a wet-laid nonwoven (papermaking) process, which can attain optimal properties in wettability, mechanical strength, thermal resistance, and electrochemical performance ...

28 ❘ ❘ ❘ 105:4 (2004) T 83 Pulp & Paper Canada aper machine designs have historically included large volume wet end processes as a necessary part of an efficient and productive papermaking facility. The conventional large volume processes, as shown in Figure 1, provide mixing and blending of thick stock components and control of entrained air from the forming section white waters. When designed...

Colloidal chemistry is a science to study the physicochemical properties of generalized colloidal dispersion systems. Polymer new comprehensive subject that studies synthesis, chemical reaction, physical chemistry, physics, processing and application polymer compounds. The development mainly experienced four periods: utilization natural polymers, modification production synthetic polymers estab...

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, ...
