  • Use of starch with synthetic metal silicates for improving a papermaking process
    Patent number: 7494565
    Abstract: The invention discloses a paper or paperboard produced from a slurry comprising cellulose fibers and an effective amount of SMS. In addition, a method for increasing retention and dewatering during the papermaking process is also disclosed. The method involves the addition of an effective amount of SMS to said papermaking process. The invention also discloses a method for increasing retention and drainage in a papermaking process comprising the steps of: adding both an effective amount of starch and an effective amount of SMS to a slurry of said papermaking process, wherein said starch is selected from the group consisting of: tapioca starch; potato starch; corn starch; waxy maize starch; rice starch; and wheat starch. Moreover, the invention comprises a method for increasing retention and drainage in a papermaking process comprising the steps of: adding both an effective amount of modified starch and an effective amount of SMS to a slurry of said papermaking process.
