Title：Talking about fiber production machinery
How can fibers be produced by machinery? This is the product of the development of science and technology in recent decades. Artificial fibers or synthetic fibers are produced by chemical synthesis, mechanical spinning and drafting using cellulose fibers or natural gas and acetylene as raw materials, which are collectively referred to as chemical fibers. These fibers are produced by chemical and physical changes and machinery. The production of chemical fibers is developing side by side with the production of natural fibers for the benefit of mankind.
With the development of science and technology, the production of raw materials for textile industry has extended beyond the field of fiber production. Can machinery and equipment for the production of man-made and synthetic fibers and the raw materials for these materials be called fiber production machinery?
The raw material for the production of man-made fiber is cotton pulp or wood pulp, and the cotton pulp and wood pulp are produced into pulp, with a complete set of host and auxiliary machines. The pulp is then crushed, aged, yellowed, dissolved, filtered, spun and post-treated to form a filament or staple of man-made fiber. The whole production line is composed of dozens of main machines and hundreds of auxiliary machines, as well as a complete set of equipment for the recovery and utilization of waste solutions. Different spinning processes, different varieties and specifications, and different sets of equipment are selected. The annual production capacity of the whole production line of staple fiber is 10,000 tons, 30,000 tons and 45,000 tons. Artificial fiber filament has semi continuous spinning and continuous spinning. The equipment selected varies with different processes.
The raw materials of synthetic fibers are mainly natural gas and acetylene gas, which are produced through polymerization, decomposition and synthesis, and belong to the discipline of chemical polymer.
Different raw materials of synthetic fibers lead to different processes and equipment for producing synthetic fibers. Traditional vinylon and polyvinyl alcohol, the raw material of vinylon, are polymerized, alcoholized, washed, dissolved, filtered, spun, and drawn with natural gas or acetylene gas to form filaments or filaments. There are dozens of main machines and hundreds of auxiliary machines for the complete set of equipment.
Traditional synthetic fibers, such as polyester, nylon, polypropylene, spandex and acrylic fibers, which are large in volume and wide in scope, are mostly made from the downstream of petroleum processing. With the development of science and technology, the change of process flow, and the connection between the previous and next processes, the connection between spinning and polyester production is generated, and the connection between polyester and the production of upstream products, terephthalic acid and ethylene glycol, forms the industrial chain of synthetic fibers.
At present, all the devices for the polymerization of terephthalic acid and ethylene glycol have been localized, and different process production lines with different process flows, single line annual output of 200000 tons, 300000 tons and larger capacity scale have been established.
Polyester has different raw materials, different uses of products, and different technical equipment. Fiber grade products are formed through esterification and polymerization, and solid phase tackifying is required after polymerization to form bottle grade and membrane grade products. The production of these products requires a complete set of technical equipment.
Different synthetic fiber materials, different spinning processes, and different production capacity of single line. For example, polyester staple fiber has an annual production capacity of 10000 tons, 30000 tons, 50000 tons, 60000 tons, and 75000 tons in Germany. The spinning and winding speed of polyester filament is improved, and the production capacity is also increased rapidly. The single line capacity of nylon industrial yarn, civil yarn, polypropylene civil yarn and carpet yarn can be determined according to the needs of the construction scale. The complete process and engineering of each product must be equipped with dozens of main machines and dozens of auxiliary machines.
After spinning, the filament of synthetic fiber also needs post-treatment and deep processing, including drafting, texturing and multifilament separation, so that synthetic fiber becomes the primary product in the market.
With the development of science and technology, the nonwovens technology of melt blown spinning and spunbonded spinning from polyester chips has become increasingly mature and developed rapidly. There is also recycling of waste polyester. These are all processed and produced by domestic equipment. With the change of polymer chemistry, many new and high-tech fibers used in aviation, aerospace, water conservancy, environmental protection, architecture, medicine, tourism, clothing and decoration have come out, including meta spun fiber 1313, para spun fiber 1414, and carbon fibers of different brands. There are also many high-performance fibers with high strength, high abrasion resistance, high temperature resistance, corrosion resistance and flame retardancy, as well as multi-component, composite, ultra-fine fibers and other differentiated fibers.
