2022On September 28th, Lycra, an international leader in textile and apparel, announced that it had signed an agreement with Qore® to become the world’s first large-scale commercialization of bio-based spandex with bio-based BDO as the main raw material production company. Recently, Lycra announced again that under their cooperation, the world’s first large-scale commercial production of biologically derived spandex has been realized, “a transformative and more sustainable spandex is about to come out.” Industrial corn will become The main raw material of bio-based spandex.
Bio-based synthetic fibers are made from natural plants or crops, through genetic engineering, fermentation Purification and other processes prepare high-purity monomers, and then undergo polymerization reactions to form polymers, which are finally prepared by processes such as melt spinning. “Made in China 2025” and “Guiding Opinions on the Development of the “13th Five-Year Plan” for the Chemical Fiber Industry” both proposed that the development of high-performance fibers and bio-based chemical fibers be the key development direction of the textile industry.
In terms of the layout of bio-based spandex, domestic enterprises have also made a lot of progress progress. In 2022, Huafon Spandex announced that the company has officially acquired DuPont’s bio-based product-related business and technology. The acquired products are used to replace some of the existing raw materials to produce polyurethane with higher bio-based content, and further promote the downstream Research and development of bio-based spandex. Duzhong Spandex has developed a spandex with a bio-based content of more than 70%, and Bangtai Spandex’s bio-based melt-spun spandex products have already passed the United States Department of Agriculture (USDA) bio-based product certification. In August 2022, Hyosung announced that its spandex product “creora bio-based” with a bio-based content of 30% has obtained the global SGS environmental protection product certification, becoming the world’s first case of commercialization of bio-based spandex.
Renewable alternatives from the source, making bio-based fibers comparable to traditional fossils Base products have a smaller carbon footprint, which plays an important role in promoting the goal of carbon neutrality. The development of bio-based spandex drives the industry’s demand for bio-based improvement of the upstream raw material BDO-PTMEG, and promotes the further development of the industrial chain towards low-carbon and environmental protection.
