METHOD FOR PREPARING REGENERATED CELLULOSE FIBRE BY TWO-STEP COAGULATING BATH PROCESS |
摘要 |
<p>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.</p> |
