资源简介：
The present invention relates to a process for the production of regenerated cellulosic fibers from a cellulosic spin dope， said process comprising the steps of treating a recycled cellulosic waste material to remove at least one of lignin， hemicelluloses， and contaminants from the recycled cellulosic waste material thereby providing a purified cellulosic intermediate product， dissolving the purified cellulosic intermediate product in an alkaline liquor to form a cellulosic spin dope， injecting the cellulosic spin dope into a coagulation bath to form a tow， washing and stretching the tow under alkaline conditions and/or acidic conditions， and cutting the tow to form regenerated cellulosic fibers.
