Engaged in setting polyester yarn, cotton yarn and other textile materials

Changshu Tianrun Yarn Steaming Co., Ltd. was founded in 2003. The company is mainly engaged in the steam setting of textile raw materials such as polyester yarn and cotton yarn – i.e., high-temperature and high-pressure steam treatment before weaving to achieve various desired effects. The company possesses more than ten steaming autoclaves imported from Taiwan, as well as over 20 years of experience in steam setting and a dedicated professional team. Over the past 20 years, based on the Changshu market, the company has gradually expanded into the Yangtze River Delta region. By 2017, it had actively started developing overseas markets. In 2018, the company added dozens of advanced double twisters and a number of covering machines to further enrich the variety of textile raw materials.


Jiangsu Derun Fiber Technology Co., Ltd. was established in late 2014. It has 14 brand-new Barmag false‑twist texturing machines (draw texturing machines), mainly producing polyester DTY in specifications ranging from 75D to 300D. The product range includes regular single‑ply DTY, color yarns, two‑ply composite yarns, high‑elastic DTY, and more. Over the past three years, the company has continuously absorbed advanced experience, actively cooperated with downstream textile customers to develop new products, and won customer trust and praise. In 2018, the company began introducing its products to overseas markets, leveraging the new “Internet+” trend to gain more market opportunities.
