It has one 10,000 tons/year PLA bi-component fiber production line, one 1,000 tons/year polylactic acid air through/thremal bonding non-woven fabric production line, and three functional polylactic acid fiber production lines.Among them, the three functional PLA fiber production lines have an annual capacity of 5,000 tons and can produce various differentiated products such as three-dimensional curled fibers, dual-component PLA fibers, profiled fiber,PLA yarn, and solution-dyed PLA fibers.

eSUN Fiber's PLA materials, PLA fibers, and non-woven fabrics are at the leading level in the industry. Among them, PLA bicomponent fibers are its leading andfeatured products, and it has achieved large-scale production and sales in the development of PLA staple, bicomponent fibers and differentiated products.The project "Efficient Bioproduction of Polylactic Acid and Technology for Fiber Preparation and Application," in which eSUN Fiber participated, was awarded the First Prize for Scientific and Technological Progress by China National Textile And Apparel Council in 2023.

Founded in 2000, formerly known as Changshu Changjiang Chemical Fiber Co.,Ltd. In 2015, it joined Hengtian Fiber Group Co., Ltd. and was renamed "CHTCCHANGJIANG PLA CO., Ltd" In December 2023, Shenzhen Esun completed theacquisition of CHTC's controlling stake and changed its name to "Esun Fiber(Suzhou) Co., Ltd."
