| 20080284054 | Use of Aqueous Naoh/Thiourea Solution in Pilot-Scale Production of Cellulose Products - The present invention relates to the use of an aqueous sodium hydroxide/thiourea solution, specifically to the use of an aqueous sodium hydroxide/thiourea solution for pilot-scale production of cellulose products, wherein sodium hydroxide constitutes 8.1%-12.0% of the total weight of the aqueous solution, thiourea constitutes 3.0%-6.0% of the total weight of the aqueous solution, and said cellulose products include regenerated cellulose filaments, films, nonwovens, as well as composite fibers and/or functional materials of protein/cellulose, chitin/cellulose, Konjac Glucomannan/cellulose, nano-crystal particle/cellulose, etc. | 11-20-2008 |
| 20080275231 | Method for Preparing Regenerated Cellulose Fiber by Two-Step Coagulating Bath Process - The present invention relates to a non-toxic process and system for pilot-scale production of cellulose products, and particularly to a process and system for pilot-scale production of cellulose products by using aqueous sodium hydroxide/urea solution pre-colled to lower than −8° C., in which cellulose could dissolved rapidly. The said process and system can be used to produce fibers, films, chromatographic packings, or nonwovens of regenerated cellulose, as well as to produce a variety of high added-value products by adding other materials such as functional materials, nano-materials, etc. | 11-06-2008 |
