Starch compositions, including cationic crosslinked starches, and methods of using those starches in papermaking are disclosed. In particular, a cationized crosslinked starch and use of the starch in the wet end system of a paper machine is disclosed. The starch compositions of the disclosure are particularly adapted for customization for specific wet end systems, and allow for modification to correspond to variations in the wet end of the papermaking machine.

Starch compositions and methods for use in papermaking

There are disclosed cationic crosslinked waxy starch products having a Brookfield viscosity of about 700 cps to about 2500 cps and a method for preparing the starch products. Also disclosed is the use of the cationic crosslinked waxy starch products having a Brookfield viscosity of about 700 cps to about 2500 cps in the production of paper products.

Cationic crosslinked waxy starch products, a method for producing the starch products, and use in paper products

The disclosure provides a process of modifying a seed based fiber (SBF) to form an enhanced fiber additive (EFA). The process includes an acid treatment step and optionally at least one fiber modification step. Preferred EFA products and uses are described.

Enhanced fiber additive; and use

The invention relates to a paper product having 0.1 to 10 percent of an acid treated seed based fiber material incorporated into the paper making composition. The remainder of the paper product can be pulp fibers, for example wood fibers. The seed based fiber material is present on the surface of the pulp fibers and imparts certain properties to the paper product formed from it.

Plant seed based fiber products and processes

A hydroxyethyl starch composition including dent corn starch and waxy corn starch wherein a portion of at least one, and preferably both, of the dent corn starch and the waxy corn starch are hydroxyethyl starch. Also disclosed are paper products comprising a fibrous web having applied thereon the starch compositions.
