Our History

Changshu Polyester Co., Ltd. was founded in 1983. In 1986, it jointly developed high strength and low elongation polyester filament with Shanghai Synthetic Fiber Institute, which has filled the domestic gap. The products are widely used in the field of wire belt rope net and so on. The company has carried out industry-university-research cooperation with Hefei Institute of Solid State Physics, Chinese Academy of Sciences, Ningbo Institute of Materials Technology and Engineering, Donghua University, Soochow University, etc., jointly undertaken the national "863" science and technology project and independently undertaken the Jiangsu Province science and technology project, and has achieved a number of scientific research achievements. Changshu Polyester Co., Ltd. is the "National Torch Plan Changshu polymer new material industry base backbone enterprise", in 2007 to undertake the national and provincial "High strength and low shrinkage polyester industrial silk (fine dener) torch plan science and technology project", the same year by the Torch Center of the Ministry of Science and Technology awarded the "National Key high-tech Enterprise". In 2018 and 2021, it was rated as a high-tech enterprise by Jiangsu Provincial Science and Technology Department. In 2017, it was awarded the "Little Giant" enterprise of Changshu City, and in 2021, the polyester fine denier industrial silk was awarded the "special, fine and new" product of Jiangsu Province.

The company has Jiangsu Province "Engineering Technology Research Center" and Jiangsu provincial "Enterprise Technology Center". It has cooperated with Donghua University to set up "Engineering Center of Research and Development of high-strength functional fiber materials", established "Functional Fiber Research and Development Center" with Soochow University Textile and Clothing Engineering College, and co-built "Differentiated synthetic Fiber Collaborative Innovation Center" with Soochow University. Founded provincial graduate workstation with Soochow University, it is a private technology enterprise in Jiangsu Province. In October 2004 obtained ISO9001:2000 quality management system certification; In August 2008, it obtained ISO14001:2004 environmental management system certification, in September 2019, ISO45001 Occupational health and safety management system certification, and in 2020, it passed the "Informatization and industrialization integrated management system" certification.

The annual investment in scientific research funds reaches about 3% of the sales. The application fields of the company's products range from high-grade apparel leather thread, ribbon, climbing rope, sunshade, insect control, special mesh cloth, etc. Has expanded to wind power base cloth, electrical wire insulation coating, safety belt, mine wind tunnel cloth, and into the scientific research, medical and other requirements of fiber with anti-static, anti-ultraviolet, flame retardant and other special fields.

Nylon and polyester functional differential fibers are special fibers that have been rapidly developed in China in recent years and are used in new energy, industrial and civil fields, with high import dependence and great market demand. Have a strong technical base of chemical fiber enterprises are actively research and development. Functional, differentiated fiber with its unique performance, especially in the fiber strength, shrinkage, wear resistance, alkali resistance, as well as the characteristics of green environmental protection, become after the upgrading of products irreplaceable varieties. The development of functional special fiber has its positive and practical significance, and in line with the national industrial policy proposed in the rapid development of "carbon fiber, aramid fiber and other new fibers and multifunctional differential chemical fiber production" requirements, therefore, the company's new plant phase I project in March 2022, the second project will be put into production in April 2023.
