November 9, 2026. Led by Huoshan County Science and Technology Bureau, a delegation from the National College of Outstanding Engineers, Donghua University visited Anhui Furuiya Down, an affiliate of Anhui Yahua Down Group, for special technical guidance and industry‑university‑research exchange. Both sides conducted in‑depth discussions on core technical challenges across the full production chain of down, with duck down odor control — a long‑standing concern in the industry — as a key topic of the exchange.

This exchange focused on common pain points in actual down production. The university‑enterprise technical teams systematically analyzed core issues including the formation mechanism of duck down odor, critical prevention‑and‑control nodes in processing, and odor‑avoidance solutions for finished‑product warehousing and circulation. Drawing on years of front‑line production experience, the technical team of Yahua Down Group briefed visiting experts on prevailing difficulties in duck down odor control across the industry. Oxidation of inherent lipids in down, residual impurities during raw‑material sorting, deviations in washing process parameters, and inadequate temperature control in sterilization may all trigger odor formation in later stages.

Leveraging cutting‑edge research achievements in textile materials science, the professor team from the National College of Outstanding Engineers, Donghua University put forward multiple actionable optimization proposals for Yahua Down’s existing production processes. Proposals covered upgrading refined sorting standards in initial raw‑material screening, adjusting targeted treatment processes for lipid residues in washing procedures, and establishing a dynamic management‑and‑control system for high‑temperature sterilization as well as temperature and humidity in warehousing environments. A full‑chain technical reference scheme for odor control covering raw materials, production and storage was thus formulated.
At the meeting, Yahua Down Group and Donghua University reached a consensus to jointly set up the “Worry‑Free Down R&D Center”. This joint R&D platform will carry out special research in fields such as iteration of down de‑odorization technology, upgrading of high‑loft down processes, construction of a traceable digital quality system, and implementation of eco‑friendly processing technologies. It will facilitate the direct application of cutting‑edge university research outcomes to the enterprise’s entire production workflow, so that technological innovation can genuinely drive quality improvement of end‑use products.

A local enterprise with nearly four decades of experience in the down sector, Yahua Down Group draws on distinctive germplasm resources in Anhui Province such as West Anhui White Goose and Chaohu Ma Duck. It has long invested in R&D targeting down cleanliness, loftiness and de‑odorization technologies. During this exchange, building on Yahua Down’s existing smart wash‑label anti‑counterfeiting and traceability system, both parties discussed the feasibility of incorporating odor‑control nodes into the full‑chain traceability system, enabling traceability and verifiability of the de‑odorization treatment process for each batch of down.

Zuo Shengcheng, Chairman of Yahua Down Group, stated: “Down odor directly affects end‑consumers’ user experience and represents a core direction for Yahua’s long‑term technical research. The visit by the university’s expert professor team delivers new theoretical support and optimization ideas for technical iteration in our front‑line production.” He added that both sides will take this exchange as a starting point to further implement industry‑university‑research cooperation, conduct joint R&D on down de‑odorization technology and high‑loft down process upgrading, and promote continuous improvement of quality standards for the local down industry.

A relevant official from Huoshan County Science and Technology Bureau remarked that this liaison serves as a practical measure for local industrial authorities to connect university scientific research resources and advance the upgrading of deep‑processing industries for county‑level characteristic agricultural products. Going forward, the Science and Technology Bureau will keep building technical exchange platforms for university‑enterprise collaboration and push for the transformation and implementation of more down‑industry technical achievements locally.
