Charles T. Currelly, first director of the Royal Ontario Museum, participated in excavations of the tomb of King Nebhepetre, now known as Mentuhotep II, (Dynasty XI) in Deir el-Bahri, Egypt in 1906. He brought to Canada many objects from the excavations, and objects that he purchased while in Egypt; these formed the initial collection of the museum. Among the objects were seven fragments of fine linen cloth with intricate pleat patterns. Recently, the cloths became the subject of a study to learn how they had retained their pleats for 4000 years. Samples were examined and analysed using polarised light microscopy, scanning electron microscopy-electron dispersive X-ray spectrometry, gas chromatography-mass spectrometry, and pyrolysis-gas chromatography-mass spectrometry. Three of the cloths were likely fragments of clothing re-purposed as bandages and were found to be saturated in mummification balms composed of resin, resin, and an essential oil characterised by a high abundance of cedrol, possibly originating from a juniper species. All seven of the cloths were found to have traces of polysaccharides from two probable sources: an arabinogalactan gum such as gum arabic or a fruit gum, and a polyglucoside, possibly starch.
加拿大安大略皇家博物馆的首任馆长查尔斯·T·卡雷利（Charles T. Currelly）于 1906 年参与了埃及代尔埃尔-巴哈里（Deir el-Bahri）的第十一王朝法老孟图霍特普二世（Mentuhotep II）墓的发掘工作。他从发掘地带回了许多文物，以及在埃及购买的文物，这些文物构成了博物馆最初的藏品。其中包括七块带有复杂褶皱图案的细亚麻布碎片。最近，这些布料成为一项研究的主题，旨在了解它们是如何在 4000 年内保持褶皱的。研究人员使用偏光显微镜、扫描电子显微镜-电子能谱法、气相色谱-质谱法和热解气相色谱-质谱法对这些布料进行了检查和分析。其中三块布料很可能是重新用作绷带的衣物碎片，它们被发现被由树脂、树脂和一种以雪松醇含量高为特征的精油组成的木乃伊油饱和，这种精油可能源自某种杜松属植物。这七块布料都被发现有两种可能来源的多糖痕迹：一种阿拉伯半乳聚糖胶，如阿拉伯树胶或某种水果胶，另一种是多葡糖苷，可能是淀粉。
