China’s fiber quality monitoring authorities have stepped up oversight of mulberry silk and Song brocade (songjin) raw materials, framing the work as protection of a national-level intangible cultural heritage craft. The push, reported in early July by China Daily citing provincial coverage, ties traditional brocade production to a modern quality-control regime.
Song brocade is one of China’s three traditional silk brocades, alongside Nanjing yunjin and Sichuan shu brocade. The technique originated in the late Northern Song period, primarily in Suzhou, and inherited the formal vocabulary of Song-dynasty woven silk. It was added to China’s first national ICH list in 2006, and in 2009 the broader traditional mulberry silk weaving technique, which includes Song brocade, was inscribed on UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity.
The brocade is woven on a loom that uses a two-warp and multiple-weft structure, allowing the weaver to express complex figured patterns through a system of compound sheds. The technique is paired with a color-blending approach known as paodao huose, in which the shuttle is changed by hand to produce soft color transitions in the woven design. The combination gives Song brocade its characteristic lightweight yet crisp hand and richly graduated pattern fields.
Quality control is a defining issue for high-end Song brocade. The brocade is woven exclusively from 100 percent mulberry silk, and the raw silk must clear more than thirty pre-weaving processes, from soaking and twisting to dyeing and finishing, before it reaches the loom. Mulberry silk’s natural luster and breathability are part of the fabric’s identity, and any compromise in raw material quality shows up immediately in the finished textile.
The fiber monitoring authority has built a full-chain inspection regime around the production cycle. Drawing on the Cocoon Silk Quality Supervision and Administration Measures, the agency now monitors mulberry silk procurement, processing, and inspection steps, and it has begun pushing standards alignment between traditional weaving know-how and modern quality metrics. Officials described the work as a way of keeping the brocade’s material purity intact while helping the craft find new commercial outlets.
The move is also being read as a way to support Song brocade’s expansion into the new Chinese-style apparel market, where the fabric’s lightness and pattern depth have made it a recurring choice for spring-and-summer jackets, qipao linings, and accessory pieces. Industry analysts note that the combination of ICH branding and verified raw material quality is increasingly used as a marketing point by Suzhou-based brocade weavers supplying national apparel brands.
