How can fibers be produced by machinery? This is the product of the development of science and technology in recent decades. Using cellulose fibers or using natural gas and acetylene gas as raw materials, chemical synthesis, mechanical spinning, and drafting produce artificial fibers or synthetic fibers, collectively referred to as chemical fibers. These fibers are produced by mechanical and physical changes. Chemical fiber production goes hand in hand with natural fiber production for the benefit of mankind.
With the development of science and technology, the production of raw materials for the textile industry has extended beyond the field of fiber production. Is it possible to say that the machinery and equipment used to produce man-made and synthetic fibers and raw materials for these materials are called fiber production machines?
Man-made fiber production of raw materials is cotton pulp or wood pulp, cotton pulp, wood pulp into pulp, a complete set of host and auxiliary machine. The pulp is then crushed, aged, yellowed, dissolved, filtered, spun, and post-treated to form filaments or staples of man-made fibers. The entire production line consists of dozens of masters and hundreds of auxiliary machines and the recovery of waste solutions. , made up of complete sets of equipment. Different spinning processes, different specifications, and different sets of equipment are also used. The annual production capacity of the whole short-filing production line is 10,000 tons, 30,000 tons, and 45,000 tons. Artificial fiber filaments are semi-continuous spinning and continuous spinning. Different process selection equipment is also different.
Synthetic fiber raw materials mainly use natural gas, but also acetylene gas, after polymerization, decomposition, synthesis and production, belonging to chemical polymer science.
Synthetic fiber raw materials are different, and the process and equipment for producing synthetic fibers are different. The traditional vinylon and vinylon raw materials, polyvinyl alcohol, are subjected to polymerization, alcoholysis, water washing, dissolution, filtration, spinning using natural gas or acetylene gas. Stretching into filaments or short filaments. There are dozens of main equipments for complete sets of equipment, and there are hundreds of auxiliary equipments.
Traditional, large amounts of synthetic fiber - polyester, nylon, polypropylene, spandex and acrylic fiber, the raw materials of these products, mostly from the downstream of petroleum processing. With the development of science and technology, the change of process flow, the connection of the upper and lower processes, and the subsequent connection of spinning and polyester production, polyester is connected with the upstream product of terephthalic acid and ethylene glycol to form a synthesis. Fiber industry chain.
At present, the devices for the polymerization of terephthalic acid and ethylene glycol have all been domestically produced, and have different processes and single-line annual production capacity of 200,000-ton, 300,000-ton, and larger-scale, different processes. production line.
Polyester has different raw materials, different uses of products, and different technical equipment. There are fiber grades formed by esterification and polymerization, as well as solid phase viscosification after polymerization to form bottle-grade, film-level products. The production of these products must have complete sets of technical equipment.
Synthetic fiber raw materials are different, spinning process is different, single-line production capacity is not the same. Such as polyester staple fiber, single-line annual production capacity of 10,000 tons, 30,000 tons, 50,000 tons, 60,000 tons, Germany has an annual output of 75,000 tons. The spinning and winding speeds of polyester filaments have increased, and the production capacity has also rapidly increased. The single-line production capacity of nylon industrial yarn, civilian yarn, polypropylene civil yarn and carpet yarn can all be determined according to the scale of construction. Each kind of product's technological complete set, the engineering complete set, the configuration craft technology equipment and so on all must have dozens of kinds of host machines and dozens of kinds of auxiliary machines to match become.
Synthetic fiber filaments need to be post-processed and further processed after they are spun, including drafting, texturing, and multifilament yarns, making synthetic fibers the primary product of the market.
With the development of science and technology, the non-woven technology of melt-blown spunlaid and spun-bonded spunlaid webs from polyester chips has become increasingly mature and rapidly developed. There is also recycling of waste polyester. These are all produced by domestic equipment and equipment. The changes in the discipline of polymer chemistry, and many high-tech fibers used in aviation, aerospace, water conservancy, environmental protection, construction, medicine, tourism, and high-end apparel and decoration, have been introduced one after another, including meta-amphiron 1313, para-aralene 1414 Different grades of carbon fiber. There are also many high-strength, high-abrasive, high-temperature resistant, corrosion-resistant and flame-retardant high-performance fibers, as well as differentiated fibers such as multi-component, composite, and ultra-fine fibers. The advent and development of these products are formed by the close integration of machinery and equipment.
Fiber production machinery is a high-tech and sophisticated technology that includes chemistry and physics. It is a systematic project that cannot be underestimated. Using a 1 gram weight of polyester raw material to pass through the island spinning process, spun into 200 km of ultrafine fibers is easier said than done? There are still many difficulties in doing these tasks. What's more, these industries are still constantly changing and developing?
In the development of the textile machinery industry today, not only the primary stage of spinning natural yarns and woven fabrics, but also the level of production of textile raw materials. Therefore, the social status and social identity of fiber production machinery should also enter a new height.
