Concomitant scouring and oxidation process for making oxidized regenerated cellulose |
| abstract |
The present invention is directed to a process of concomitant scouring and oxidizing cellulose in a solution of nitrogen oxide and perfluorinated hydrocarbon and subsequent washings of the oxidized fabric with isopropyl alcohol,where the perfluorinated hydrocarbon solvent preferably has a boiling point in the range of between about 30 DEG C and about 100 DEG C, the nitrogen oxide concentration in the solution is in the range between about 2% and about 12% by weight, the reactants are maintained at a temperature between about 25 DEG C to about 40 DEG C for a total time duration of at least about 7 hours, the oxidized cellulose is subsequently washed with Fluorinert solvent, cold water, 50:50 isopropyl alcohol:water and 100% isopropyl alcohol, followed by drying with warm nitrogen gas. The resulting oxidized fabric exhibits a residual oil content substantially equivalent to fabric that has been scoured in hot aqueous and detergent but does not suffer the shrinkage associated with aqueous scouring. |
