项目摘要

The characteristics of lightfastness of dyed clothes were investigated by the use of monochromatic and multi chromatic radiations. The effects of substrate and ultraviolet ray absorbent (UVA) on the lightfastness were examined. One of the most distinguishable features of this research is the compilation of action spectrum which shows the wavelength dependency in the fading of dyed materials. As a result, the following characteristics were obtained:1. Four kinds of disperse dyes were selected to dye polyester clothes. These specimens were examined to reveal their fading characteristic under the experimental technologies as mentioned above. Moreover, the effect of UVA on the prevention of fading of the dyed specimen was studied. The usage of 1% o. w. f. UVA gave the control effects of 25% to 55% on four kinds of disperse dyes on polyester material. It was confirmed that the effect of UVA was high in the radiation of ultraviolet ray. Further, the prevention effect of fading was observed to be higher than the absorbing efficiency of UVA. This result was interpreted that UVA action is depending not only on UV filtration. but partially on controlling the radical oxidation reaction.2. Specimens of JIS blue scale were examined. Both of polyester and nylon were used as a substrate. The fading prevention effect of UVA was observed on polyester material. However, on the nylon specimens, no UVA effect was observed. It is considered that main fading mechanism on nylon is depending on the reduction and therefore UVA which may be related to control the oxidation process does not give the influence on the fading.

采用单色和多色辐射对染色后的织物的耐光性进行了研究。探讨了基材和紫外线吸收剂对织物耐光性的影响。本研究最显著的特点之一是作用光谱的编制，它显示了染色材料褪色的波长依赖性。其结果是，获得了以下特性：1。选用四种分散染料对涤纶织物进行染色。在上述实验技术条件下，对这些样品进行了测试，以揭示它们的褪色特性。此外，研究了UVA对防止染色试样褪色的影响。使用1% O。W. F. UVA对四种分散染料在涤纶织物上的防染效果为25%~ 55%。证实了在紫外线辐射中UVA的影响高。此外，观察到褪色的防止效果高于UVA的吸收效率。这一结果被解释为UVA作用不仅取决于UV过滤。但部分地取决于控制自由基氧化反应。对JIS蓝标试样进行了检查。聚酯和尼龙都被用作基底。观察了UVA对聚酯材料的防褪色效果。然而，在尼龙样品上，没有观察到UVA效应。认为尼龙褪色的主要机理是还原作用，因此UVA对尼龙褪色没有影响，UVA可能与控制氧化过程有关。
