Abstract
PURPOSE: A specific amount of cellulose alkali is aged until the Hottenroth number reaches a specific value, carbon disulfide and sodium carbonate are added thereto to form a solution, which is wet spun to produce the titled fiber suitably used as baby napkin of paper because of its high absorption and friction coefficient.
CONSTITUTION: An usual alkali cellulose that contains 7W9% cellulose and 5W 6.5% total alkali and is aged to 6W11 Hottenroth number in H, Z is combined with 0.5W6%, of carbon disulfide and 2W6% of sodium carbonate based on cellulose and they are dissolved sufficiently. Then, the spinning is conducted in a usual coagulation bath at 40W70°C to obtain the objective viscose rayon fiber. The resultant rayon has preferably higher than 170% degree of swelling in water and higher than 0.250 dynamic and higher than 0.170 static friction coefficients.
