Talking about the fiber production machinery
?????How can the fibers be produced by machinery? This is the product of the development of science and technology in the last few decades. Using cellulose fibers or the use of natural gas, acetylene gas as raw material, through chemical synthesis, mechanical spinning, drawing and produce artificial fiber or synthetic fiber, collectively referred to as the chemical fiber. These fibers are produced by means of chemical and physical changes. Chemical fiber production, development and production of racing together bridle to bridle natural fiber, for the benefit of mankind.
?? Science and technology has developed, the raw material of textile industry raw material production and extends out, beyond the field of fiber production. Production of synthetic fibers and synthetic fibers and the production of raw materials for the production of mechanical equipment, can be referred to as the fiber production machinery??? Artificial fiber raw material is cotton pulp or wood pulp, cotton pulp and wood pulp production into pulp, a main and auxiliary set. Pulp through pulverizing, ageing, yellowing, dissolving, filtering, spinning and after processing, synthetic fiber filament or staple fiber formation, the entire production line by dozens of host and one hundred kinds of auxiliary equipment and recycling of waste solution, using complete sets of equipment and composition. The spinning process is different, the variety of different specifications, the selection of complete sets of equipment are also different. The annual production capacity of the whole production line of the short silk yarn is ten thousand ton, 30 thousand ton, and the. Man-made filament yarn has a semi continuous spinning and continuous spinning. The process of different selection of equipment is also different.
The raw material of the synthetic fiber is mainly used for natural gas, and also has acetylene gas, which is produced by polymerization, decomposition and synthesis, and belongs to the chemical polymer science.
Raw materials of synthetic fiber, synthetic fiber producing process and equipment is different, traditional vinylon and vinylon raw material polyvinyl alcohol, the use of natural gas or acetylene gas after polymerization and alcoholysis, washing, dissolving, filtering, spinning, drafting a filament or staple fiber. The host has dozens of complete sets of equipment, auxiliary by hundreds of components.
The traditional, large amount of a wide range of synthetic fiber polyester, nylon, polypropylene, polyurethane and acrylic fiber, these products, raw materials, mostly from downstream of the petroleum processing. With the development of science and technology, process, process under the connection, and then produce the spinning of polyester production connection, polyester and upstream product of terephthalic acid and ethylene glycol production and connection, formed the synthetic fiber industry chain.
At present, terephthalic acid and ethylene glycol were polymerization device have all realized the localization, and the different processes and single line with an annual output of 20 million tons, 30 million ton and larger production scale, different process production line.
Different, polyester raw material products for different purposes, with different technical equipment. There is the formation of fiber grade through esterification, polymerization, there is a need to re - stick after the polymerization, the formation of bottle grade, film grade products. The production of these products have a complete set of technical equipment.
Different synthetic fiber materials, spinning process is different, the production capacity of single line is not the same. Such as polyester staple fiber, single line annual capacity of 10000 tons, 30 thousand tons, 50 thousand tons, 60 thousand tons, Germany has an annual output of. Polyester filament spinning, winding speed is increased, the production capacity is also rapidly increasing. Nylon filament, civil silk, polypropylene filament, single capacity of civil carpet yarn can be based on the scale of construction and. Each a product of complete sets of technology, engineering sets, configuration technology and equipment have dozens of host dozens of kinds of auxiliary and.
Synthetic fiber filament spinning also need after processing, deep processing, including stretching, texturing and multifilamentary wire, synthetic fiber become the market's primary products.
With the development of science and technology, from polyester slice of meltblown spinning, spun spinning into network nonwoven technology become more and more mature and developed rapidly. And recycling of waste polyester. These are produced by domestic equipment and equipment to process. Changes in polymer chemistry, and many for aviation, aerospace, water conservancy, environmental protection, construction, medicine, tourism and high-end clothing, decorative high-tech fiber have been published, including between an Aramid 1313, para aramid 1414, different grades of carbon fiber. There are many high strength and high grinding, high temperature resistant, resistant to corrosion and flame retardant high performance fiber, and multicomponent, composite, superfine fiber arithmetic don't fiber.
