PAPER PRODUCTS HAVING WET STRENGTH FROM ALDEHYDE-FUNCTIONALIZED CELLULOSIC FIBERS AND POLYMERS |
摘要 |
PURPOSE: A paper product is provided to include a polyhydroxyl polymer being reactive to an aldehyde-functionalized cellulosic fiber and a cellulosic fiber. CONSTITUTION: Paper products having high initial wet strengths are disclosed. The paper products comprise cellulosic fibers having free aldehyde groups, which fibers are combined with a water-soluble polymer having functional groups that are reacted with the aldehyde groups to form bonds joining the fibers. In a preferred embodiment, the cellulosic fibers contain a polysaccharide in which the hydroxyl groups of at least a portion of the repeating units of the polysaccharide are cis-hydroxyl groups, preferred repeating units being man nose and/or galactose. Similarly, the water-soluble polymer is preferably a polysaccharide in which the hydroxyl groups of at least a portion of the repeating units of the polysaccharide are cis-hydroxyl groups. Preferred polysaccharides are derived from one or more sugars selected from man nose, galactose, allose, altrose, gulose, talose and lyxose.
