The unearthed textile is an important material for human existence.
The unearthed textile is an important material for human existence.
The material, property, design, spinning and weaving technology of unearthed textile is precious wealth left by ancient people [2].
Since ancient textile is like an encyclopedia, studying unearthed textiles not only can help us to understand the ancient science and technology, but also can help us to explore the relationship between textile and society, economy, politics, religion, culture, and art.
Data collection and reduction The data of unearthed textiles came from references such as Cultural Relics, Archaeology, Journal of Archaeology, and so on.

Materials and Methods For this work, a set of Bézier-based metamaterials was generated based on the methodology proposed in [15], but now controlling the position of the free control point by means of two independent variables: the distance r from the origin and the angle β describing its position.
The deformation of Bézier-based cantilever lattice-beams is strongly influenced by the curvature, which in turn affects the apparent stiffness of these lattice materials.
