More Information
Summary:The invention provides methods and compositions for increasing the strength of a paper sheet. The method involves adding to the paper sheet an amine containing polymer. The amine containing polymer interacts with materials such as GPAM or starch to make the paper stronger in terms including tensile strength, surface strength and bulk strength. 本发明提供了用于提高纸张的强度的方法和组合物。该方法涉及向所述纸张中添加含胺聚合物。所述含胺聚合物与诸如GPAM或淀粉的材料相互作用以使得纸在包括抗张强度、表面强度和块体强度的方面更强。
