    摘要： A process for making an absorbent composite including absorbent fibers, superabsorbent polymer and, optionally, thermoplastic fibers and other ingredients is provided. The synthesis (i.e., polymerization) of the superabsorbent is completely integrated into the process for forming the absorbent composite. Specifically, the polymerization of superabsorbent is initiated from within a plurality of absorbent and/or thermoplastic fibers, which are then formed into a web. The integrated process eliminates the need for separate manufacture of superabsorbent polymer prior to the fiber forming and web forming processes. Also, the superabsorbent polymer thus formed tends to disperse better and remain adhered to the absorbent and/or thermoplastic fibers, providing a stable and uniform absorbent composite for various end use applications.

    摘要： In the manufacture of creped tissue products, the adhesion between the tissue sheet and the creping cylinder can be increased by applying one component of an adhesive complex to the sheet and another component of an adhesive complex to the creping cylinder. When the two components are brought into contact at the pressure roll nip, an adhesive complex is formed which adheres the sheet to the creping cylinder.
