Description
Technical Field
The invention relates to the technical field of textile fibers, in particular to a device and a method for recovering and filtering regenerated PET fibers.
Background
China is a large country for producing and using fibers, the total consumption of the fibers exceeds thirty million tons every year, and the consumption of Polyester (PET) fibers is the largest and accounts for about 35 percent of the market. With the rapid development of textile industry and the environmental protection of chemical production in recent years, the yield of PET fibers gradually becomes a bottleneck restricting the development of textile industry. Meanwhile, the consumption of polyester also brings some subsequent environmental problems, for example, the amount of leftover waste of textiles and old clothes based on polyester is considerable, so that the environmental pollution caused by various waste chemical fiber waste materials is more and more serious, and the disposal of waste based on polyester becomes a troublesome problem. The establishment of recycling from waste to raw materials is an effective method for solving the two problems. The recycling of the waste polyester is realized, the problem of environmental pollution (waste polyester garbage comprises waste clothes, polyester films, mineral water bottles and cola bottles) can be solved, and the current situation that the yield, the scale and the like of the textile for industry in China are seriously insufficient at present can be improved. The inventory of terylene renewable resources in China mainly comprises waste polyester and waste textiles, at present, the social annual production of polyester bottles exceeds 500 million tons, and the inventory reaches 2500 million tons; the inventory of waste textiles reaches 2600 million tons, wherein 1800 million tons of chemical fibers and 800 million tons of natural fibers. Taking waste textiles as an example, the annual storage capacity of the waste textiles in key cities and areas in China is only 350 ten thousand tons at present. Therefore, under the strategic conception of strengthening ecological civilization construction and developing green recycling economy, the potential of recycling the waste textiles is great. The realization of the reasonable reuse of the waste polyester has great economic benefit and social benefit, and is an important field for developing circular economy in the textile industry of China.
The regenerated PET fiber is fiber which takes regenerated polyester as a main raw material, and comprises short silk, long silk and the like, the raw material sources mainly comprise waste drinking water and beverage packaging bottles, membranes, clothes and non-woven fabrics, waste silk and waste blocks generated in the production process of polyester and fiber, and the polyester bottle pieces are taken as the main raw material sources. The main recovery technologies of the regenerated fiber raw materials at present comprise physical recovery, chemical recovery, recycling recovery, direct recovery and infrared treatment recovery, wherein most of the technologies adopt a chemical method and a physical method to recover waste polyester materials, and then the recovered waste polyester materials are processed into regenerated PET fibers. The fabric developed by using the regenerated PET fiber as the raw material is not only environment-friendly but also meets the requirements of sustainable development, and with the continuous improvement of recycling technology in China, the quality of the regenerated PET fiber is also continuously improved, so that the fabric has a tendency of gradually replacing the original PET fiber.
However, when the existing recycled PET fibers are recycled and prepared, the materials cannot be efficiently and uniformly stirred by the stirring device when the materials are dissolved by stirring, meanwhile, the filtering device of the existing device after stirring cannot be disassembled and cleaned, and after the device is used for a long time, the filtering device can cause blockage, so that the filtering efficiency of the device is affected, the preparation of the fibers is affected, and the prepared fibers cannot be rapidly and effectively dried after filtering.
