Abstract
A fluff pulp or other pulp, comprises 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; an amine-containing anti-static agent; and pulp. Methods of making and using the pulp, as well as articles therefrom, are provided.
Claims38
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 coco alkyl dimethylbenzyl ammonium chloride;
- and (c) pulp.
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 first mixture;
- contacting at least one amine-containing anti-static agent comprising coca alkyl dimethylbenzyl ammonium chloride with the first mixture and raising the pH to a second pH, which is higher than the first pH, to form a fluff pulp mixture;
- forming a web from the fluff pulp mixture;
- and drying the web, to make the fluff pulp sheet.
