The present technology is directed to fluff pulps with improved odor control as well as methods of making such fluff pulps. A fluff pulp is provided that includes a bleached kraft fiber and a copper ion content from about 0.2 ppm to about 50 ppm by weight of the bleached kraft fiber. The bleached kraft fiber includes a length-weighted average fiber length of at least about 2 mm, a copper number of less than about 7, a carboxyl content of more than about 3.5 meq/100 grams; an ISO brightness of at least 80; and a viscosity from about 2 cps to about 9 cps.

Odor control pulp composition

This invention relates to a paper substrate containing high surface sizing and low internal sizing and having high dimensional stability, as well as methods of making and using the composition.

Paper substrates containing high surface sizing and low internal sizing and having high dimensional stability

A fluff pulp or other pulp, comprises a multivalent cationic metal ion selected from the group consisting of Al, B, Mn, Cu, Cu, Zn, Sn, Sn, water-soluble salt thereof, or combination thereof; an amine-containing anti-static agent; and pulp. Methods of making and using the pulp, as well as articles therefrom, are provided.

Composition containing a multivalent cationic metal and amine-containing anti-static agent and methods of making and using

Expandable microspheres formed by suspension polymerization using a shot growth method are provided. The microspheres are formed of a continuous, gas impermeable shell surrounding a blowing agent. The shell includes a first polymer layer formed from primary monomers and a second layer that includes a chemically reactive monomer or a high Tg monomer. To form the microspheres, the primary monomers are polymerized in a reaction vessel to an approximate 90% polymerization, at which time a secondary monomer that is either a monomer having a Tg of at least 85&#xb0; C. or a chemically reactive monomer, is added to the reaction vessel to drive the polymerization reaction to completion. The outer layer thus contains either a larger amount of the high Tg monomer or a chemically reactive monomer that possesses the ability to covalently bond a cationic species. The microspheres may be used in papermaking processes to increase the paper bulk.

Expandable microspheres and methods of making and using the same

This invention relates to composition containing expandable microspheres and at least one ionic compound and having a zeta potential that is greater than or equal to zero mV at a pH of about 9.0 or less at an ionic strength of from 10M to 0.1M, as well as methods of making and using the composition.

Compositions containing expandable microspheres and an ionic compound, as well as methods of making and using the same

The specification discloses a method for making a paper material having a reduced tendency to cut human skin. The method includes providing a papermaking furnish containing cellulosic fibers and from about 0.5 to about 5.0 wt % by weight dry basis expandable microspheres, forming a paperboard web from the papermaking furnish, drying the web, and calendaring the web to a caliper of from about 11.0 to about 18.0 mils and a density ranging from about 7.0 to about 12.0 lb/3000 ft/mil. Papers formed according to the method and articles formed therefrom are also disclosed.

Cut resistant paper and paper articles and method for making same

This invention relates to composition containing expandable microspheres and at least one ionic compound and having a zeta potential that is greater than or equal to zero mV at a pH of about 9.0 or less at an ionic strength of from 10M to 0.1M., as well as methods of making and using the composition.
