all flowers bloom together

Polyester fiber is the largest chemical fiber category and an important raw material to meet the needs of the national economy, but most of the polyester raw materials come from petroleum. With the implementation of the national "double carbon" strategy, bio based polyester materials have been paid more and more attention.

Professor, School of Material Design and Engineering, Beijing Institute of Fashion Technology Zhang Wenjuan The development status of bio based polyester fiber was introduced, and the research results of bio based PTT fiber, bio based PLA fiber and related catalysts were emphatically introduced. She believes that China is the world's largest producer and consumer of polyester fiber, and polyester fiber accounts for more than 80% of chemical fiber. Therefore, in the long run, the bio based polyester fiber is an inevitable trend. She proposed that in the future, we should break through a number of core key technologies of biological and chemical conversion of bio based monomers, create a number of new varieties of bio based polyester fibers, and form the original innovation system of bio based polyester industry; Excavate the characteristics of bio based polyester, and improve the added value of bio based polyester fiber products through fabric development and brand building; Innovative design is carried out from the development chain and the industrial chain, highlighting the product characteristics, breaking through the key technologies such as single system preparation and polymerization spinning, strengthening the research and promotion of key technologies in the application of the whole field, and reducing the R&D and production costs.

General Manager of Anhui Fengyuan Biofiber Co., Ltd Fan Yaqing Under the title of "Non grain line production of polylactic acid helps the green development of fiber industry", we shared the high-value application of crop straw, low-carbon and biodegradable biological material polylactic acid, the application of polylactic acid fiber, industrial background and industrial policies. He said that the biological fermentation technology route with grain as raw material has certain limitations. Fengyuan Biology uses crop straw as raw material to produce polylactic acid, realizing the high-value application of crop straw, ensuring national food security, and promoting social green development, sustainable development and ecological civilization. He introduced that the basic properties of PLA are between polyester and nylon, with light weight, low melting point, energy saving and environmental protection in production and processing, but its softening temperature is also low, so attention should be paid to temperature control in the subsequent processing process. The degradation of polylactic acid is artificially controllable, which ensures that the performance of the finished products of polylactic acid is durable and stable before being discarded, and can meet the needs and requirements of downstream applications. It is one of the inevitable choices for green and sustainable development.
