摘要： Process for producing formed cellulosic articles, such as fibers, filaments, sheetings, membranes or tubes, comprising a) extruding a solution of cellulose in an aqueous amine oxide, particularly N-methylmorpholine N-oxide, through an extrusion die via an air gap and coagulating the formed article in an aqueous precipitation bath containing amine oxide, and b) passing the formed article through at least one washing stage for removing residual amine oxide from the article, characterized in that the liquor of the precipitation bath in the precipitation stage and/or the washing liquor of the washing stage(s) is treated with ultra-violet radiation. In this manner the formation and growth of coatings, films and slime deposits caused by microorganisms is avoided on parts of the plant which come into contact with said liquors containing the amine oxide.

摘要： A regenerated cellulose-encapsulated active substance and a method for encapsulating an active substance in a regenerated cellulose matrix are disclosed. The distribution of the active substance is preferably substantially homogeneous within the matrix of regenerated cellulose. The regenerated cellulose (i) has about the same molecular weight as the original cellulose from which it is prepared (ii) is substantially free of added substituent groups relative to the starting cellulose and is also substantially free of entrapped ionic liquid degradation products.

摘要： A method of manufacturing cellulose microspheres is proposed which is high in productivity, and takes into consideration the safety and environmental aspects. The cellulose microspheres are manufactured by mixing at least three parts by weight of a water-soluble polysaccharide with an alkaline cellulose solution containing one part by weight of cellulose to prepare a minute dispersion in which are formed minute droplets made of cellulose-rich phase, and coagulating and regenerating the minute droplets.

摘要： Waste raw uncoated and/or coated (such as saran, nitrocellulose and vinyl) regenerated cellulose film is treated to recover its plasticizer and cellulose components for recycling in the manufacture of regenerated cellulose film. The platicizer is first recovered from comminuted waste film particles via extraction with water. The moist comminuted film particles are then converted to viscose, from which coating solids, if any, are removed. The viscose is thereafter employed in the manufacture of regenerated cellulose film.
