This is a research about the fabrics attached to the remains of the Okjeon old tomb which was built around the early 5th century to the mid of the 6th century. Most of the remains have one kind of fabric attached to them, but there are cases where different sorts of fabrics are attached, where one kind is attached in layers, and there are also cases where the layer is made of different types of fabrics. Although they are made of warps and wefts with no twists, there can be an S twist on the weft or on both the warp and weft, and only one Z twist can be seen. There are 81 fabrics of plain weaved, one of transformed plain weaved and five 4-end complex gauze in these remains. The sparsest plain weaved fabric has the density of 7.4 strands/cm, while the most dense fabric has the density of 148.2$ imes$129.1 strands/cm and 0.046$ imes$0.061/mm thickness in thread. All the fabrics observed by SEM are hemp except one silk.
