Abstract : Three ounce per square yard nylon cloths in greige, scoured, and dyed conditions were subjected to oxygen aging exposure of 300 psi at 158F for 96 hours. The expected 10 percent loss in breaking strength by oxygen aging was exceeded by 2 samples. Laundering produced no strength change but dry cleaning greatly increased oxygen aging strength losses. Room temperature dried perchloroethylene and toluene extracted cloths had strength losses up to 55 percent when oxygen aged. High temperature drying (250F for 1/2 hr) of a toluene extracted sample before oxygen aging eliminated the strength loss produced by toluene retention. (Author)
