Abstract:

Sheets of cellophane containing 0.87 ferric nitrate 0.2 ferric ion, were prepared by impregnating the cellophane with its own weight of a 0.036 MOLAL SOLUTION OF FERRIC NITRATE. Findings indicated that the treated cellophane suffered a complete loss in tensile strength when exposed for 300 hr and lost about 25 of its original strength after a 150-hr Fadeometer exposure. Degradation accelerators other than ferric ion on cotton were also used. Acenaphthene had a significant degrading effect on cotton. Several combinations of catalysts which were tested on cotton are ferric ion plus thionin, ceric ion as cerric nitrate plus thionin, ferric ion plus 2-anthraquinone sodium sulfonate, and ceric ion plus 2-anthraquinone sodium sulfonate. The strength losses caused by the combinations containing ferric ion were no greater and in most cases were a little less than the sum of the strength losses caused by the ferric ion and organic compound, individually. Most of the catalysts tested on cotton were tested on nylon fabric. In initial studies the degradation of nylon was determined only as loss in breaking strength.
