On September 24, Jiangsu Deli Chemical Fiber Co., LTD., a subsidiary of Hengli Petrochemical Co., LTD., five new products - "high uniformity ultra soft polyester fiber", "fine polyester fiber", "hydrophilic fast drying polyester fiber", "hydrophilic flame retardant functional polyester fiber", "hydrophilic antibacterial functional polyester fiber" passed the provincial new product identification.

Among them, the product of "super soft POLYESTER fiber with high uniformity" has been unanimously approved by the appraisal committee, which believes that its overall technology is at the leading level in China and fills the gap in China.

It is understood that DELI chemical fiber took the lead in the domestic implementation of melt direct spinning 5-8D/6f high-uniformity ultra-soft polyester fiber large-scale production, the fiber is the domestic bus density of the most fine polyester fiber, broke the technical bottleneck. At the same time, the production technology of the product "A kind of High-uniformity ultra-fine polyester fiber production equipment and preparation method" has also been authorized by the State Intellectual Property Office.

Adhering to the concept of "make a wire to be the best", Hengli Petrochemical is striving for excellence in the field of microfiber. In 2021, the company started to develop finer fibers based on the microfiber 15D/72f. Team to overcome the difficult development process, innovation, through the design of the spinneret, component equipment renovation and assembly process of innovation, the development of new oil godet superfine fiber device, technologies such as the modification of winding, drafting assembly optimization solution in the production of superfine fiber components out of silk, spinning tension fluctuation difference is big, drafting broken wires and molding difficult technical problems. In that year, 5-8D/6f high-uniformity ultra-soft polyester fiber was born, Hengli Petrochemical became the first domestic enterprise to mass-produce this fiber.

At PRESENT, THE market activity OF the fiber is gradually opened, can be used in the electronic information industry, mobile phone circuit board, radio wave shielding substrate, and considerable profit, compared with conventional fiber profit of about 10 times. Not only create greater value for the company, but also provide strong support for the high-quality development of the national advanced functional fiber industry!

The corporate power behind technology
