As a result of analyzing Tang Dynasty silk samites and restoring the weaving techniques that created them, the opening of Silk Road resulted in the exchange of commodities, culture and technology between the east and west that became more and more frequent during the Tang dynasty. The warp-faced compound weave (jin-silk) that was popular from Warring States period to Wei and Jin dynasties was gradually replaced by the weft-faced compound weave (wei-silk). The motifs of the silk were greatly affected by the Middle and Western Asia. Floral patterns combined with animals suggested a mixture of Chinese and western styles, which was called, historically, Ling Yang Gong Yang. Weaving technology developed from use of the multi-heddle loom to the drawloom in Tang dynasty. Introduction of the drawloom led to great progress in weaving efficiency and artistic expressiveness in textile motifs.
