1. A fluff pulp or other pulp, comprising: (a) a multivalent cationic metal ion selected from the group consisting of Al+3, B+3, Mn+2, Cu+2, Cu+3, Zn+2, Sn+2, Sn+4, water-soluble salt thereof, or combination thereof;(b) an amine-containing anti-static agent comprising one or more of: a dialkyl ester quaternary ammonium salt, a triethanolamine-ditallow fatty acid, fatty acid ester of an ethoxylated primary amine, an ethoxylated quaternary ammonium salt, or a coco alkyl dimethylbenzyl ammonium chloride; and(c) pulp. 2. The pulp of claim 1, wherein the amine-containing anti-static agent comprises one or more of: a dialkyl ester quaternary ammonium salt, a triethanolamine-ditallow fatty acid, fatty acid ester of an ethoxylated primary amine, an ethoxylated quaternary ammonium salt. 3. The pulp of claim 1, wherein the amine-containing anti-static agent comprises a dialkyl ester quaternary ammonium salt. 4. The pulp of claim 1, wherein the amine-containing anti-static agent comprises a triethanolamine-ditallow fatty acid. 5. The pulp of claim 1, wherein the amine-containing anti-static agent comprises a fatty acid ester of an ethoxylated primary amine. 6. The pulp of claim 1, wherein the amine-containing anti-static agent comprises an ethoxylated quaternary ammonium salt. 7. The pulp of claim 1, wherein the multivalent cationic metal ion is selected from the group consisting of Al+3, B+3, Cu+3, water-soluble salt thereof, or combination thereof. 8. The pulp of claim 1, wherein the multivalent cationic metal ion is selected from the group consisting of Al+3, B+3, water-soluble salt thereof, or combination thereof. 9.

The process of claim 16, wherein the forming comprises one or more of contacting the fluff pulp mixture with a table in a papermaking machine, removing at least a portion of water from the fluff pulp mixture with a suction box under a table in a papermaking machine, or a combination thereof. 18. The process of claim 16, wherein the first pH is <5.0, and wherein the second pH is ≧5.0. 19. A process for making a fluff pulp sheet, comprising: contacting a multivalent cationic metal ion selected from the group consisting of Al+3, B+3, Mn+2, Cu+2, Cu+3, Zn+2, Sn+2, Sn+4, water-soluble salt thereof, or combination thereof with a composition comprising fluff pulp fibers and water at a first pH, to form a fluff pulp mixture;forming a web from the fluff pulp mixture; andapplying at least one amine-containing anti-static agent to the web and raising the pH to a second pH, which is higher than the first pH, to make the fluff pulp sheet, wherein the at least one amine-containing anti-static agent comprises one or more of: a dialkyl ester quaternary ammonium salt, a triethanolamine-ditallow fatty acid, fatty acid ester of an ethoxylated primary amine, an ethoxylated quaternary ammonium salt, or a coco alkyl dimethylbenzyl ammonium chloride. 20. The process of claim 19, wherein the forming comprises one or more of contacting the fluff pulp mixture with a table in a papermaking machine, removing at least a portion of water from the fluff pulp mixture with a suction box under a table in a papermaking machine, or a combination thereof. 21. The process of claim 19, wherein the first pH is <5.0, wherein the first pH is raised to second pH after formation of the web, and wherein the second pH is ≧5.0.
