“…The nylon yarns did not demonstrate this difference, possibly because of their very low rates of degradation. These findings are in agreement with those of Hirt and Searle [26] who have indicated that aging of lamps and filters reduces xenon-arc radiation intensity due to solarization of the filters and deposits forming on the lamp envelope. Based on this preliminary study, only exposures conducted within the lamp age limits of 200-1050 hr were used to give the general results of each exposure.…”

The effects of xenon-arc radiation, using an Atlas Weather-Ometer and a clear glass pyrex filter system, on the breaking strength, extension-to-break, and the energy-to-break for several nylon, polyester, and polyester/cotton yarns were compared to these of outdoor exposure behind window glass. Both types of exposure resulted in similar, related rates of loss for these properties for all yarns. Lamp age in the Weather-Ometer intluenced degradation rates in some cases. All nylon yarns degraded slowly during Weather-Ometer exposure and rapidly outdoors behind window-glass, in comparison to polyester, while the polyester/cotton yarns degraded at similar rates in both locations. Yarn-denier variation and the presence of an optical, brightener had no detectable effect on degradation rates. Sensitization by anatase in nylon and polyester yarns occurred during outdoor exposure, but not during Weather-Ometer exposure.

“…The effect of 521 hours on the Pyrex glass outer filter in a 6000-W device, reported by Searle et al (1964) is shown in Figure 7.5. Similar data have been published by Coblentz andStair (1929, 1934) and by Capron and Crowder (1975).…”

“…11 According to a study, only 5% of the total irradiated natural sunlight has sufficient energy to initiate effective photodegradation. 54 The need for continuous illumination for an efficient photocatalytic process has diverted solar utilization to an articial UV lampdriven process.…”
