Abstract
An improved market pulp and process for making the same by adding a composite material are described. The composite material includes cellulose nanocrystals, cellulose nanofibers, or another high aspect ratio, high surface area cellulose material (or a starch, or both) and a crosslinking compound that crosslinks a portion of the surface hydroxyl groups to form a 3-D matrix. Adding the composite material to market pulp has been shown to improve the strength of twice-dried paper products, made from such an enhanced market pulp. By crosslinking a portion of the surface hydroxyl groups in the market pulp to form a 3-D matrix, a first drying step may be accomplished without loss of benefits afforded when the market pulp is later re-pulped to make a paper product.
