Chemical crosslinking is an established method for improving the wet performance of paper. In chemical process, covalent bonds are formed between cellulosic surfaces. The intra- and inter-fiber increase paper’s strength reduce its water absorptivity. majority published studies concern treatments with glyoxal, citric acid (CA), or 1,2,3,4-butanetetra-carboxylic (BTCA). most severe disadvantage C...

Because there is a lack of wood resources in many countries, this work focused on pulp and paper production from the waste agricultural residues non-wood plants. The aimed to nitrate-alkaline black mustard (Brassica Nigra L.) camelina (Camelina Sativa L.). were selected due expanding planted areas these crops Czech Republic. To characterize chemical composition camelina, cellulose, lignin, ash,...

Abstract Pulp refining is an essential process step prior to paper production. The contribution of fines production during the resulting strength so far has mostly been considered qualitatively. A quantitative and experimental evaluation regarding their effect not yet published. Unbleached softwood kraft pulp was refined using a PFI mill disc refiner at different intensities. Prior handsheet fo...

The presented research project describes the development of a copy paper product from recycled egg carton fiber material. included laboratory handsheet and machine-made produced on 12-inch (304 mm) wide Fourdrinier machine which was operated at speed 6.4 ft/min (1.95 m/min).
 final had content 70% 30% northern bleached softwood Kraft as reinforcement material to avoid sheet breaks machine....

Kraft mills have the potential to pre-extract hemicellulose from wood as another value added product. The impacts of pre-extracting xylan on pulp and handsheet properties, sodium and sulfur balances, and chemical make-ups in the kraft pulping process of Eucalyptus grandis were assessed. Xylan extractions using white liquor, green liquor, and NaOH were done under varying extraction times, temper...
