What Yi Jinn Industrial does

Yi Jinn Industrial Co., Ltd. (宜進實業, Taiwan Stock Exchange ticker 1457) is a Taiwan-based textile manufacturer founded in 1981, specializing in polyester processed yarn and specialty functional fibers. The company produces eight core product lines — basic polyester processed yarn (30D/72F to 1200D/288F), linen-like fiber, recycled eco-friendly fiber (from Far Eastern New Century's recycled PET bottles), air-covered yarn, dope-dyed color fiber, cationic dyeable fiber, high-elasticity fiber (up to 86% elasticity improvement), and two-tone fiber — marketed globally under its self-owned 'Sea Gull' (海鷗牌) and 'Green Guard' brands.

The business operates as a vertically integrated B2B group. After acquiring Hongzhou Fiber (1413) and Guangming Silk Weaving (4420) in 2017, Yi Jinn became a top-3 POY (partially oriented yarn) producer in Taiwan, with chairman Chan Cheng-tian (詹正田) simultaneously chairing Hongzhou. The company has built a specialty fiber portfolio through technology partnerships: exclusive Taiwan production rights for Cocona's 37.5 technology fiber (achieving 98%+ quality yield within 2 months of trial), and a joint development with DAZZEON for nano-copper antibacterial fiber launched at the 2018 TITAS exhibition.

Yi Jinn's revenue model combines textile manufacturing (hardware sales to garment manufacturers, sportswear brands, and textile mills worldwide) with a growing real estate investment and development operation. The company has committed NT$6 billion (approximately US$190M) over two years to commercial office developments in Nangang and Xizhi, including the joint 'Farglory Yi Jinn I-CITY' project with Farglory Group, with the chairman explicitly stating real estate is now a core business. The company is publicly listed, has paid its highest cash dividend since 1998 (NT$0.6/share), and received Net Zero certification from Taiwan's ETC in 2023.
