The Key Scientific Research Base of Textile Conservation (China National Silk Museum), State Administration for Cultural Heritage was commissioned by Archaeology Institute of the Chinese Academy of Social Sciences to study the textiles unearthed from a Zoroastrian cemetery in Pamir Jirzankal. Fiber identification, dye testing and weaving structure analysis were carried out on the samples. The results show that 1) the fiber materials include silk and wool; 2) dyes such as madder, indigo and protoberberines were found, and 3) the weaving structure mainly contains silk tabby and polychrome woolen taquete. Combined with other historical and archaeological data, the above research results have been interpreted so as to provide other valuable information.
