Chemically modified pulp fiber

摘要: The wet strength softness absorbency, absorbency rate and other valuable properties in paper products, tissues, wipes, towels, etc. can be improved by using, the forming process, a cellulosic material comprising carboxymethyl cellulose associated with monomeric or polymeric cationic additive material. A process of invention comprises fiber surface carboxymethylation an aqueous medium followed blending modified fibers under varying conditions tissue towel products. is typically that preferentially associates group on surface. affinity between positively charged groups to negatively carboxyl improves various attributes
