《自然》周刊1993年3月4日号发表了维也纳大学的一封读者来信,称中国丝绸早在公元前一千多年就在古埃及使用。该来信引用的考古证据是:“我们通过电子显微镜仔细观察一具在底比斯出土的木乃伊的头发取样,发现了在鬈发间有一束类似丝绸的织物。为了证实这些样品是否是丝绸品,我们采用了多重内部反射红外线试验法,对之进行了无损伤鉴定。结果光谱清楚地鉴别出它是丝绸。” In a March 4, 1993, issue of the letter from a reader at the University of Vienna, Nature said that Chinese silk was used in ancient Egypt as early as 1000 BC. The archaeological evidence cited in the letter was: "We examined the hair of a mummified mound unearthed in Thebes by electron microscopy and found that there was a silk-like fabric in the middle of the wig.To confirm whether the samples were silk, We used a multiple internal reflection infrared test to identify it as nondestructive and the result was clearly identified as silk by the spectrum.
