    摘要: Methods are provided for creating covalent bonding of webs by combining cellulosic fibers having a carboxyl content approximately greater than 7 meq/100 g with one or more crosslinking agents. In a first step, a carboxyl group is placed onto a fiber. In an embodiment, the fiber is then reacted with an oxazoline-functional polymer which has been combined with a polycarboxylate compound. Heat is applied to the treated web, and this enables formation of a cross-linked bridge in the form of a covalent bond. In an embodiment, the covalent bonding of the carboxylated cellulose pulp webs utilizes oxazoline-functional polymers and polyacrylic acid. The oxazoline polymer in combination with polyacrylic acid should form a network polymer with covalent bonds to the cellulose carboxyl groups. The non-woven web may be strengthhened by covalent bonding, thereby improving overall wet/dry strength of the final product.

    摘要: An ink jet recording paper capable of compatible with high speed ink jet printers is provided. By using, as a fiber material, mercerized pulp obtained by applying an alkali treatment to pulp, an ink jet recording paper of high ink absorption speed and high ink coloring density is formed. Since the paper itself has excellent ink absorption speed, there is no requirement for applying coating for improving the ink absorption and it can be used as non-coated type ink jet recording paper.

    摘要: Differentially densified fibrous structures, methods for making same, and processes for treating fibers used in the fibrous structures are provided. More particularly, fibrous structures comprising two or more regions, at least one of which exhibits a density that is at least 1.6 times greater than another region within the fibrous structure, methods for making such fibrous structures and non-naturally occurring fibers useful in such fibrous structures are provided.

    摘要: A method for treating secondary fiber to achieve wet strength while retaining repulpability is provided. In an embodiment, the method involves supplying a first line of secondary fiber which represents a total supply of secondary fiber. The method has a further step of removing a portion of the total supply of secondary fiber in the first line and transporting the portion into a second line. The second line is treated with a cationic resin treatment. A third line supplies virgin fiber. The third line and the first line are combined. Next, the treated secondary fiber in the second line is combined with the mixed contents of the first line and third line. Separation of the virgin fiber line from the secondary fiber line at initial stages of the process lowers cationic demand for the system, and reduces an amount of resin required to treat the system.
