PDT fiber is a bio-based fiber with broad future application prospects.

Polyethylene terephthalate multicomponent glycol ester fiber, referred to as PDT fiber, is a bio-based PET fiber produced by spinning polyol terephthalate multicomponent glycol ester. PDT fiber raw materials can be converted from biomass resources and are low-carbon, environmentally friendly, and green. Under the background of carbon neutrality and carbon peak strategies, PDT fiber is expected to gradually replace some traditional polytrimethylene terephthalate fibers (PTT ), polyethylene terephthalate fiber (PET), etc., have broad application prospects in the future.

PDT fiber is a new type of fiber material with good stretchability, resilience, antistatic properties, dyeability, etc. It can be blended with natural fibers such as wool and has broad application prospects in functional clothing, decorative materials and other fields. my country is a major textile production and export country, and the PDT fiber market has a large space for development. However, due to high costs, the large-scale production and application of PDT fiber is subject to certain restrictions.

According to the “China polyethylene terephthalate multi-component glycol fiber (PDT fiber) industry market situation monitoring and future from 2023 to 2027 released by the Industrial Research Center The Development Prospects Research Report” shows that my country has independent intellectual property rights for PDT fiber, and its technical level has reached an international leading position. my country’s PDT fiber-related companies include Dacheng Group, Haitian Materials, etc. Among them, Haitian Materials is a domestic leader in the development and application of PDT fiber.

PDT fiber is mainly obtained by polymerizing bio-based ethylene glycol or bio-based terephthalic acid. The synthesis process is mainly direct esterification method (PTA method), which involves esterification, pre-polycondensation and final polymerization. Bio-based ethylene glycol is one of the raw materials for PDT fiber production. In China, bio-based ethylene glycol suppliers include Haitian Technology, Dacheng Group, Jilin Boda Biochemical, Changchun Yu Bio, etc. There are various preparation processes for bio-based terephthalic acid, and relevant global companies include Primus in the United States, Gevo in the United States, and Avantium in the Netherlands.

Against the background of increasingly depleted fossil resources and intensified environmental pollution, low-carbon circular economy has gradually become a global consensus. Bio-based products have the advantages of environmental friendliness and renewable raw materials. They are an important breakthrough in the strategy of replacing fossil resources and an urgent need for high-quality and green development of the global economy. It is estimated that in the next ten years, more than 20% of the world’s petrochemical products will be made of Bio-based product alternatives. As a new bio-based fiber, PDT fiber is bound to have broad development space.

Industry analysts said that PDT fiber has the characteristics of low carbon, environmental protection and green, and is used in functional clothing, decorative materials and other fields. Extensive and broad market development prospects. my country is a major country of chemical fiber. Under the strategic background of carbon neutrality and carbon peaking, the transformation and upgrading of the chemical fiber industry will be the general trend, and the bio-based fiber industry will usher in broad development space. PDT fiber is a bio-based fiber. my country currently has scale and technological advantages. As manufacturing costs decrease in the future, the PDT fiber market is expected to further expand.
