ABSTRACT:
A process for improving the radiation resistance of cellulosic fabrics is disclosed. Fabric is immersed first in a 23% caustic solution for 15 minutes and then in a 5% caustic solution for 15 minutes. The excess caustic is removed and the fabric padded to 105% wet-pickup using neutralized pentafluorobenzoic acid. The fabric is then cured at 130.degree.-140.degree. C. for 6-8 minutes.
