The cellulose pulp with α-cellulose higher than 90% and polymerisation degree of range of 450~625 was treated with 14%~16% sodium hydroxide solution for 30~40 min under temperature of 40~50°C, and blended with urea in the ratio of 1:2~3. The product was reacted in xylene as solvent at 137°C for 2~3 h.
