Preparation of viscose by a reverse method, using wet cellulose

Conclusions

It is possible to prepare viscose in a single apparatus by treating wet cellulose by the reverse method, in which impregnation with carbon disulfide precedes treatment with a waster solution of caustic soda.

Use of the reverse method affords the possibility of preparing a viscose of higher quality as compared with the viscose prepared by the known method, in which either dry or wet cellulose is used.
