Longfu’s Polylactic Acid (PLA) filament with anti-bacterial effect receives a warm welcome from the Chinese market
Jun 24, 2024 ｜ by Zhong Mengxia
A recent news on CCTV highlighted the growing trend of antibacterial deodorizing textiles and the associated effects. The topic has generated significant interest and debate on social media, with the search for "antibacterial and deodorant textiles" becoming a popular query. Because this product uses polylactic acid, this topic has also aroused widespread discussion. The product is not only biodegradable but also has excellent natural and durable anti-sensitive skin-friendly properties, as well as moisture permeability and quick-drying properties. It is also flame retardant and provides warmth. These qualities have made it a highly favored product among consumers.
For instance, a polylactic acid silk fabric exhibits a superior antibacterial rate of over 99% against three major bacteria, showcasing an impressive antibacterial effect. This makes it an excellent antibacterial deodorant solution. As the first domestic production of high-end PLA filament brand enterprise, Longfu Recycling Energy Scientech Co., Ltd. Chairman Duan Jianguo introduced the current market demand for PLA products. Longfu’s high-end PLA filament orders have increased significantly, and the production workshop is operating at full capacity now.
In the future, Longfu will take the new quality productivity as the lead, take the low carbon industrial park as the platform, take the high quality production base as the support, take "Xing Yuan" and "He Yuan" as the two core brands, and strive to build a brand new Longfu that focuses on the two major development fields of recycled fibers and bio-based new materials!
Brand empowerment to build a new green ecology
"In addition to its unique functionality, PLA is made from renewable starchy raw materials (corn, cassava, sugar cane, etc.) produced by photosynthesis, which not only "turns waste into treasure" and contributes to rural revitalization, but is also healthy, environmentally friendly and green, and can be returned to nature through biodegradation, which has excellent green and low-carbon features. For example, compared with polyester T-shirts, PLA T-shirt production process can reduce carbon emissions by 86 percent." Duan Jianguo said: "Polylactic acid can be blended with traditional natural cotton, hemp, wool and silk and also other chemical fibers such as spandex, PTT blends made of fabrics, and the market application space is huge."
In order to realize green empowerment, after the implementation of the national "plastic ban", Longfu aimed at new business opportunities, cooperated with Zhu Meifang’s team, based on the State Key Laboratory for Modification of Chemical Fibers and Polymer Materials (SKLFPM), did innovative research and development of more than 30 varieties of cross-shaped, trefoil-type, hollow-type, and other series of moisture-absorbent filaments, and successfully linked with the industry chain upstream and downstream enterprises to achieve the development and mass production of high-end PLA filament-"He Yuan silk", and established a 10,000-ton high-end PLA filament production base. In 2021, Longfu cooperated with academician Zhu Meifang's team to develop and apply the project of high value development of domestic high-quality polylactic acid and its fiber industry chain. And it won the First Prize of Technical Invention of Chinese Materials Research Society.
"He Yuan Silk is the core brand that Longfu focuses on. It can realize multiple functionalities at the source without adding any antibacterial functional factors and additives in the manufacturing process, which is a truly natural, healthy and green product." Duan Jianguo said that this product highlights its sustainability,, it is natural, skin-friendly, soft and comfortable, as well as healthy and protective. The company has established a complete traceability system and certification standards from raw materials, filaments to downstream products throughout the life cycle, so that each PLA product has a unique "identity card". Through cooperation and authorization, the certified PLA products containing Longfu's genes not only represent high quality, but also guarantee safety and health.
"In the future, Longfu will join hands with the upstream and downstream enterprises of the industrial chain through brand empowerment, and continuously expand the application space of PLA filament, leading the new consumption." Duan Jianguo introduced that Longfu has set up Longchuang Fuyuan Fiber Science and Technology Co., Ltd. in Shanghai, established a green fiber brand operation center, led by the two brands of "Xing Yuan" and "He Yuan", relying on the front-end of the Longfu Low-Carbon Industrial Park, the middle of the docking fabric merchants, and the downstream of baby and children's wear, sports wear and home textile products and other brand manufacturers, through brand authorization, to achieve the value of the whole industrial chain symbiosis.
Creating the first recycled polyester industry chain
Longfor has integrated the concept of green and low-carbon development into the DNA of enterprise development from the very beginning of its establishment, and resolved to walk out of a high-end, differentiated, green and characteristic development road.
In order to avoid homogenization competition, Duan Jianguo bravely jumped out of the "comfort zone", increased scientific research investment in the recycling of waste polyester, under his leadership, after countless failures and difficulties, and finally succeeded in the development of the "Technology for the production of recycled polyester filament yarn from waste polyester bottle chips". This technology solves the world-wide technical problems of 100% production of polyester filament yarn from waste polyester bottle chips, and has won 8 national patents. on July 7, 2007, the first regenerated polyester filament production line using waste polyester bottle chips as raw material was put into production, completely rewriting the history of China that it can only produce staple fibers from waste polyester bottles.
In 2011, Longfu and Donghua University set up a joint research and development center. Professor Zhu Meifang is the technical director of the center, led the technical team to overcome the problems that waste polyester can not directly produce polyester filament. Five technical achievements have passed the provincial and ministerial level appraisal. It fills the gaps in the country, and reachs the international leading level. Not only it obtained the authorization of the invention of 13 patents, but also won the first prize of the Science and Technology Advancement issued by China National Textile and Apparel Council, the third prize of the Science and Technology Advancement of Shandong Province and more than 10 awards. We have won more than 10 awards, such as the first prize of scientific and technological progress of China Textile Federation, the third prize of Shandong Province, etc. ...... Longfu has participated in the formulation of 4 national standards, 7 industry standards and a number of association standards as the main drafting unit, and its two products have been listed in the program of "National Key New Products" of the Ministry of Science and Technology.
In addition Longfu continuously extends the industrial chain, and it established the world's first complete industrial chain from recycling of waste polyester bottles, processing of bottle chips, production of recycled polyester filament yarn and weaving of recycled polyester blankets. Nowadays, Longfu recycles and reuses 5 billion used polyester bottles every year, and produces 6 million household blankets; it can save 1.2 million tons of oil and 1.7 million tons of coal every year, and its products are exported to Europe, America, Japan and South Korea and other countries and regions.
It is worth mentioning that in the "Celebration of the 70th Anniversary of the Founding of New China" and the "100th Anniversary of the founding of the Communist Party of China", red carpet made from plastic bottles was paved to Tiananmen Square, fully demonstrating the brand value of Longfu. The company has made a lot of contributions to the green development of China’s textile industry.
As the pioneer of recycled polyester filament and PLA filament, Lonfu has an annual production capacity of 50,000 tons of high-quality recycled polyester filament and 10,000 tons of PLA filament, and has successively passed the certifications of GRS, Intertek, Oeko-Tex Standard100, and Green Fiber, and has been honored as a national "Green Factory" and a national "Industrial Product Eco-design Demonstration Enterprise" by the Ministry of Industry and Information Technology, and successfully passed the acceptance of "waste polyester resource recycling and high-value utilization of recycling economy national standardization pilot project".
In the future, Longfu will take the new quality productivity as the lead, take the low carbon industrial park as the platform, take the high quality production base as the support, take "Xing Yuan" and "He Yuan" as the two core brands, and strive to build a brand new Longfu that focuses on the two major development fields of recycled fibers and bio-based new materials!
