Publication number: 20130040121Abstract: Thermally expandable crimped hollow fibers having expandable regions interconnected with crimped portions are provided. The crimped hollow fibers may be formed from any hollow polymer fiber that is capable of being crimped and is reactive to heat. Pressure, such as from two opposed mating crimping dies, is applied to portions of a hollow polymer fiber to compress or crimp portions of the fiber, thereby leaving uncrimped or expandable regions containing an expandable substance. In use, the crimped hollow fibers may be contacted with cellulose fibers in the wet-end section of the paper-making process and the resulting mixture formed into a web of entangled fibers. Heat from the dryer section expands the expandable substance in the expandable portion of the crimped hollow fiber to bulk the thus formed paper product. The crimped hollow fibers are especially useful in papers having a basis weight from about 20 to about 200 gsm.Type: ApplicationFiled: July 20, 2012Publication date: February 14, 2013Applicant: INTERNATIONAL PAPER COMPANYInventor: KAPIL M.

Publication number: 20120040200Abstract: The present invention relates to a sizing or coating composition that, when applied to paper substrate, creates a substrate having improved waterfastness, surface strength, and surface strength as measured by resistance to abrasion. In addition, the present invention relates to paper substrates containing the composition, as well as methods of using and making the paper substrate and composition.Type: ApplicationFiled: October 27, 2011Publication date: February 16, 2012Applicant: INTERNATIONAL PAPER COMPANYInventors: MICHAEL F.

Publication number: 20120018109Abstract: A paper having thereon a coating composition including at least one pigment and at least one starch is provided. The pigment and the starch may be added to the surface of the paper at a size press during the formation of the paper in a ratio of at least 1:1. Papers coated with the coating composition have an enhanced surface ink density in a subsequent printing or tinting process at an ink usage that is equal or substantially equal to that used to tint conventional, uncoated papers. Accordingly, a paper coated with the coating composition requires the utilization of a lesser amount of ink than that required for conventional file folders to achieve the desired end color. In addition, the coating composition permits for an enhancement in print and/or tint quality if a reduction in ink use is not utilized. A method of forming a file folder is also provided.Type: ApplicationFiled: July 22, 2011Publication date: January 26, 2012Applicant: International Paper CompanyInventors: KAPIL M. SINGH, MICHAEL F. KOENIG, LARRY HOLLMAIER

Publication number: 20110274856Abstract: An article in the form of a paper substrate having a first surface and a second surface and an acid-resistant water-swellable substrate coating which provides an ink-receptive porous surface on at least one of the first and second surfaces. The substrate coating has an amount of an acid-resistant coating pigment sufficient to impart a Parker Print Smoothness value of at least about 4 to the at least one of the first and second surfaces and is dispersed in an acid-resistant water-swellable crosslinked polymer coating pigment binder matrix, with the coating pigment having from about 30 to 100% larger coating pigment particles with a mean particle size above about 1 micron in diameter. Also, a method for preparing such coated paper substrates.Type: ApplicationFiled: April 8, 2011Publication date: November 10, 2011Applicant: INTERNATIONAL PAPER COMPANYInventors: Michael F.
