PET whole bottle recycling method will promote the circular development of the textile industry
In the past ten years, the chemical fiber industry has actively promoted the development of circular economy. The scale of the circular economy industry, which mainly recycles waste polyester, has grown rapidly, and the level of technical products has continued to improve. Recycled polyester refers to fibers made from recycled waste polyester bottle flakes, polyester blocks, polyester waste silk and other raw materials. It mainly produces three-dimensional curly hollow fibers (3D~15D), cotton-type, and medium-length polyester short fibers. , and polyester filament, recycled bottle flakes, etc. The large-scale production of these products has replaced a large number of primary products, effectively alleviating the serious shortage of oil resources in our country. By the end of 2010, my country’s annual production capacity of recycled polyester was more than 6 million tons, and the output was nearly 4 million tons, accounting for about 80% of the world’s total output. China has become a major producer and consumer of recycled polyester.
The recycling and cleaning of PET bottles is the first step in the recycling industry chain. In view of the complex and varying bottle source conditions in different countries and regions, adopting different cleaning processes and solutions is the key to the regeneration cleaning process. Our country has accumulated a lot of experience in the field of PET bottle flake recycling and cleaning technology. Zhejiang Baolute Environmental Protection Technology Co., Ltd., which has been exploring this field for more than 20 years, has developed a complete set of cleaning processes, techniques, and cleaning solutions and successfully introduced them to the market. Its equipment is currently exported to many countries around the world.
“Achieving a polyester cycle is an urgent need of the industry, and it is entirely possible to achieve it.” Wang Huaping, a professor at the School of Materials Science and Engineering at Donghua University, believes that there are two cycles in the polyester cycle life cycle. One is from polyester to to polyester bottles, to fibers and fabrics; another cycle is from polyester to fibers, to fabrics and fibers. The chemical fiber recycling system with recycled polyester as the main body is a systematic project, which involves the development of new technologies and new devices for efficient recycling, separation, cleaning, and spinning to achieve process continuity, cleaning, finishing automation, sealing, Production scale and stabilization. This will not only improve the existing drinking bottle recycling technology system, but also accelerate the construction of a recycling and finishing system for work clothes, home textiles, and industrial fabrics
Hangzhou Fuxing Group Co., Ltd. has spent 8 years building a complete industrial chain from PET bottle recycling to high-end carpet production, allowing people to see the bright prospects of the circular economy.
Shaoyang Cloth Machinery Co., Ltd. is one of the earliest companies in my country to get involved in the manufacturing and development of complete sets of equipment for recycling polyester bottle flakes and recycled polyester short fibers. The complete set of “imitation large chemical fiber” equipment it developed occupies the largest domestic market. Sales market share, the high-strength and low-elongation complete equipment with an annual output of 40,000 tons is the equipment optimized for the domestic recycled polyester short fiber production line. Huang Weijiang, a senior engineer at the company, hopes to promote this complete set of equipment domestically to help promote the development of circular economy.
However, the progress of circular economy still requires support from many aspects. Wang Huaping believes that the recycled polyester industry has low profitability, strong public welfare, and large investment scale. He hopes that the state will set up special funds and loan interest discounts for the revitalization of the recycled polyester industry to encourage investment by advantageous enterprises, and provide special government subsidies in accordance with international carbon emission standards. In addition, it is recommended that the country set up relevant national support plans and 863 projects for the recycling system construction, recycling technology, recycled products and quality and safety of recycled polyester.
