Cellca: new method to produce cellulosic fibres 
Meinander, K 
1987 
English 
Two Finnish companies, Neste Oy. and Kemira Oy. Sateri, have collaborated in evaluating a new route to produce regenerated cellulose fibre. The Cellca process is based on the reaction between cellulose and urea, whereby a stable cellulose derivative, cellulose carbamate, is formed. If the carbamate groups are evenly distributed, the derivative is soluble in alkali. Fibres can be spun from cellulose carbamate solutions by conventional spinning techniques with only minor modifications. Discussion includes the effect of degree of substitution. Development is at the level of pilot scale operation. New products or applications are being revealed. See also abstract 1987/3102.
