    摘要: Pulp fibers can be treated with chemical additives with a minimal amount of unretained chemical additives present later in the process water. The present invention is a method for preparing chemically treated pulp fiber. A fiber slurry is created comprising process water and pulp fibers. The fiber slurry is transported to a web-forming apparatus of a pulp sheet machine thereby forming a wet fibrous web. The wet fibrous web is dried to a predetermined consistency thereby forming a dried fibrous web. The dried fibrous web is treated with a chemical additive thereby forming a chemically treated dried fibrous web. The dried fibrous web contains chemically treated pulp fibers. The chemically treated pulp fibers retain from between about 10 to about 100 percent of the applied amount of the chemical additive when the chemically treated pulp fibers are redispersed in water.

    摘要: Modified polysaccharides (such as starches, gums, chitosans, celluloses, alginates, sugars, etc.), which are commonly used in the paper industry as strengthening agents, surface sizes, coating binders, emulsifiers and adhesives, can be combined into a single molecule with modified aliphatic hydrocarbons, which are commonly utilized, in conjunction with cationic moieties, as softeners, debonders, lubricants and sizing agents. The resulting molecule is a modified polysaccharide having an aliphatic moiety which can provide several potential benefits, depending on the specific combination employed, including: (a) strength aids that do not impart stiffness; (b) softeners that do not reduce strength; (c) wet strength with improved wet/dry strength ratio; (d) debonders with reduced linting and sloughing; (e) strength aids with controlled absorbency; and (f) surface sizing agents with improved tactile properties.

    摘要: Modified polysaccharides (such as starches, gums, chitosans, celluloses, alginates, sugars, etc.), which are commonly used in the paper industry as strengthening agents, surface sizes, coating binders, emulsifiers and adhesives, can be combined into a single molecule with amphiphilic hydrocarbons (e.g. surface active agents) which are commonly utilized in the paper industry to control absorbency, improve softness, enhance surface feel and function as dispersants. The resulting molecule is a modified polysaccharide having surface active moieties which can provide several potential benefits, depending on the specific combination employed, including: (a) strength aids that do not impart stiffness; (b) softeners that do not reduce strength; (c) wet strength with improved wet/dry strength ratio; (d) debonders with reduced linting and sloughing; (e) strength aids with controlled absorbency; and (f) surface sizing agents with improved tactile properties.
