Corn stalk as a raw material for papermaking

摘要

Cornstalk was evaluated to verify the potential as a raw material for papermaking. Average fiber length of cornstalk was similar to those of hardwood, but small amount of long fiber fraction was observed. The important features of cornstalk are higher hemicellulose content and lower lignin content than those of wood. Therefore, the cooking and bleaching chemicals are required to get good quality of pulp. Another important thing is that cornstalk pulp does not require the refining. Deflaking was enough to get enough strength properties. Disadvantages of cornstalk pulp were lower bulk and opacity, but it can be overcome by the proper combination of hardwood pulp and filler.
