Conclusions

The effect of ionizing radiation on the molecular weight characteristics and ability to be dissolved of high-molecular, high-viscosity sulfite cellulose has been investigated.

A radiation dose range of 5–10 kGy has been established, on absorption of which by high-molecular, high-viscosity sulfite cellulose, the degree of polymerization is reduced to 840. The reactivity is increased to 80/11 (% CS2/% NaOH) and the share of the main fraction, having a DP of 200–800, rises to 52–60%. Irradiation of cellulose is suitable for use in the manufacture of viscose fibre.
