    • 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.
    • 本发明公开了由包含纤维素纤维和有效量的SMS的浆料制成的纸或纸板。 此外,还公开了在造纸过程中增加保留和脱水的方法。 该方法涉及向所述造纸过程添加有效量的SMS。 本发明还公开了一种在造纸方法中增加保留和排水的方法,包括以下步骤:向所述造纸方法的浆料中加入有效量的淀粉和有效量的SMS,其中所述淀粉选自 的:木薯淀粉; 土豆淀粉; 玉米淀粉; 蜡质玉米淀粉; 大米淀粉; 和小麦淀粉。 此外,本发明包括一种用于增加造纸方法中的保留和排水的方法,包括以下步骤:将有效量的改性淀粉和有效量的SMS加入到所述造纸方法的浆料中。
