20080241536 | Method for processing cellulose in ionic liquids and fibers therefrom - The present application is directed to a process of dissolving cellulose in an ionic liquid, regenerating the fibers and forming a nonwoven web. In particular it is directed to fibers produced from cellulose dissolved in ionic solvents and extruded by the meltblowing process. Bonded nonwoven webs can be obtained in the process. | 10-02-2008 |
20090084509 | Dissolution of Cellulose in Mixed Solvent Systems - A method for dissolving cellulose in which the cellulose based raw material is admixed with a mixture of a protic intercrystalline swelling agent and an ionic liquid at a temperature of 25° C. to 180° C. for a time sufficient to dissolve the cellulose based raw material. The molar ratio of protic intercyrstalline swelling agent to ionic liquid may be 0.05 to 1.5 moles of protic intercrystalline swelling agent to 1 mole of ionic liquid. | 04-02-2009 |
20090088564 | Dissolution of Cellulose in Mixed Solvent Systems - A method for dissolving cellulose in which the cellulose based raw material is admixed with a mixture of a dipolar aprotic intercrystalline swelling agent and an ionic liquid at a temperature of 25° C. to 180° C. for a time sufficient to dissolve the cellulose based raw material. The molar ratio of dipolar aprotic intercrystalline swelling agent to ionic liquid is 0.05 to 1.5 moles of dipolar aprotic intercrystalline swelling agent to 1 mole of ionic liquid. Dipolar aprotic intercrystalline swelling agents do not include imidazole based agents or amine based agents. | 04-02-2009 |
20100300329 | FIBER CEMENT BOARD WITH MODIFIED FIBER - A building material product comprising a cementitious binder, an aggregate and cellulose reinforcing fibers wherein the cellulose reinforcing fibers have been treated with cationic or nonionic oil. The resulting fiber when included in a fiber cement composite results in improved deflection of the composite at peak loading as well as improved impact strength while maintaining overall board strength. | 12-02-2010 |
20100300330 | FIBER CEMENT BOARD WITH MODIFIED FIBER - A building material product comprising a cementitious binder, an aggregate and cellulose reinforcing fibers wherein the cellulose reinforcing fibers have been treated with oil which is bound to the fiber by a retention aid. The resulting fiber when included in a fiber cement composite results in improved deflection of the composite at peak loading as well as improved impact strength while maintaining overall board strength. | 12-02-2010 |
20130206037 | Composite Polymer Molded Product - A molded part comprising 10 to 50 weight % wood pulp fiber, 45 to 85 weight % thermoplastic polymer and having an edge extending between two faces wherein the edge has two tactile defects or less per foot or less of edge length. | 08-15-2013 |
20150376835 | ESTERIFIED CELLULOSE PULP COMPOSITIONS AND RELATED METHODS - Esterified cellulose pulp compositions produced in high yield from commercially available wood pulp sources, methods for making the esterified cellulose pulp compositions, and articles prepared from the esterified cellulose pulp compositions. | 12-31-2015 |
20150376836 | ESTERIFIED CELLULOSE PULP COMPOSITIONS AND RELATED METHODS - Esterified cellulose pulp compositions produced in high yield from commercially available wood pulp sources, methods for making the esterified cellulose pulp compositions, and articles prepared from the esterified cellulose pulp compositions. | 12-31-2015 |
