Laboratory tests were conducted to better understand effects on the papermaking process and handsheets when recycled copy paper furnish was treated with combinations of nanofibrillated cellulose (NFC), cat-ionic starch, colloidal silica, cationic retention aid (cPAM; polyacrylamide). Dosage-response experiments helped define conditions leading favorable processing outcomes, including dewatering...

This study aimed to evaluate the effect of size press coating on two types recycled papers using different nanofibrillated cellulose (NFC) and cationic starch (CS) physical mechanical properties. Wheat straw was used as a source, NFC obtained through oxidative enzymatic pretreatments. Recycled fluting coreboard were coated with starch/NFC blends at various concentrations (0.5%, 1%, 2%, 3%, 4%) ...

objective(s):the aim of this study was to improve flowability and compressibility characteristics of starch to use as a suitable excipient in direct compression tabletting. quasi-emulsion solvent diffusion was used as a crystal modification method. materials and methods: corn starch was dissolved in hydrochloric acid at 80˚c and then ethanol as a non-solvent was added with lowering temperature ...

A series of experiments were conducted on recycled pulp samples for the novel purpose of determining the efficacy of employing soy protein flour to increase the strength of dry paper. Values of short span compression and tensile strength were the prime criteria for comparison based on industrial considerations. Various conditions were considered to uncover effective schemes for applying the soy...

Abstract The use of paper dry strength additives is one the methods for producing packaging boards with a lower grammage while maintaining mechanical properties. In present work, papers were formed using dissolving grade kraft fibres, fibres and carboxymethylated cellulose (CMC) modified (C-kraft fibres), either cationic starch (CS), anionic polyacrylamide (APAM) or polyelectrolyte complexes (P...

The present paper reports the successful elaboration of exfoliated plasticized starch-based nanobiocomposites. This was made possible by using cationic starch as a new clay organomodifier to better match the polarity of the matrix and thus to facilitate the clay exfoliation process. To demonstrate the efficiency of this new approach, either natural (MMT-Na) or organomodified (OMMT-CS) montmoril...
