At present, the acetate fiber technology monopolized by several large foreign companies, production varieties in addition to cigarette tow and medical, chemical tow, only textile acetate fiber with more than a dozen varieties, the United States, Britain, Canada, Italy and other countries are now accelerating the development of new varieties to adapt to the needs of the popular fabrics market. Now, the international market price of acetate, filament about 4600 U.S. dollars / ton, the bundle of about 3830 U.S. dollars / ton.
Acetate fiber industry in China started relatively late in the late 1950s, the varieties are also limited to cigarette acetate tow, textile acetate fiber imports. China's textile imports of acetate fiber mainly from the United States Celanese Corporation, Japan Mitsubishi Corporation, the United Kingdom's Kautauerz Company, etc., imports of about 2,000 tons per year, in addition to direct imports of fabrics more than 700 million meters and a considerable number of filament fabrics of acetic acid, China's annual demand for acetic acid fiber is about 10,000 tons or more, and at present, the market price of domestic acetate fiber is about 36,000~38,000 yuan / ton. 38000 yuan / ton.
China's acetate and acetate tow of the main manufacturers are Nantong Acetate Co., Ltd., Guangdong Xinhui Acetate Fiber Factory, Xi'an Hui'an Chemical Factory, Jilin Chemical Factory, Wuxi Film Factory, Baoding Film Factory, Guangdong Zhongshan Sugar-coated Acetate Fiber Pilot Workshop, Zhuhai Acetate Fiber Company, Kunming Acetate Fiber Company, etc., with a total production of about 5.5 million tons of acetate, 9.6 million tons of tow.
Acetate do cigarette filter material, flexible, non-toxic, tasteless, good thermal stability, small suction resistance, filtering effect is significant, can selectively adsorb the harmful components of the cigarette, while retaining a certain amount of nicotine without losing the taste of cigarettes, since 1953 into the market, popular, the market outlook is better, and China's current acetate tow still have a considerable number of imports. Shortfall of about 20,000 tons or so, the import price of about 3830 U.S. dollars per ton.
Acetate staple fiber made of nonwoven fabrics can be used for surgical dressings, and wound non-adhesion, is a high-level medical hygiene materials. Acetate staple fiber can also be blended with cotton or synthetic fibers, made of a variety of fabrics with excellent performance.
Acetate filament in the chemical fiber most cool silk, elegant luster, bright dyeing, dyeing fastness, soft and smooth feel, light texture, low moisture retention, good elasticity, not easy to wrinkle, with good drape, thermoplasticity, dimensional stability, can be widely used to do clothing lining material, leisure suit, pajamas, underwear, etc., but also with polyvinyl chloride, polyester, nylon filaments and silk composite made of Composite silk, weaving a variety of men's and women's fashion, men's and women's dresses, high-grade sportswear and western-style fabrics, but also the development of satin fabrics and woven fabrics, decorative satin, embroidery products substrate, gingham silk, woven silk, vinyl silk ammonia wrapped yarn and so on. Currently in the United States, Britain, Japan, Italy, Mexico, South Korea, Russia, Pakistan and other countries and regions favored by consumers, especially in the U.S. market has been in short supply, while China's annual demand for more than 10,000 tons per year, due to the high price of imports, about 4,600 U.S. dollars / ton, there are only a small number of imports, about 2,000 tons imported each year, a lot of textile factories more than Substitute to solve the problem of the shortage of acetate fiber, so the textile acetate fiber market outlook is very promising.
According to the U.S. Celanese company's offer, the construction of an annual output of 6,000 tons of acetate filament production line, the introduction of a full set of technical equipment requires about 60 million U.S. dollars, of which investment in vinegar equipment accounted for about 80% of the total investment, the system of acetic acid filament equipment accounted for about 20% of the total investment in the production line, if you take the road of localization, only the introduction of key equipment, the scale of production line investment of about 300 million yuan About. Production of two-type acetate filament, unit cost it about 24300 yuan / ton or so, the product unit price of about 3800 yuan / ton, then the unit product to achieve profits and taxes 13700 yuan, profit 7520 yuan, taxes 2470 yuan, the payback period of about 4. 5 ~ 5 years, therefore, investment in the construction of China's production line of acetic acid fibers, the economic benefits of a good, small investment risk.
In terms of China's current development of acetic acid fiber, mainly to meet domestic needs and reduce imports, the scale of production should be based on capital investment in the development of localization technology and the supply of raw materials, product market demand to choose the appropriate scale, and then with the maturity and improvement of the localization technology and then expand the scale. 1, in terms of the acetic acid filament bundles to the construction of an annual production capacity of 4,000 tons to 6,000 tons of Domestic production line is appropriate, textile acetate fiber can be considered to build an annual output of 2,000 tons to 3,000 tons of acetate filament production line is appropriate, the total scale can be considered in the range of 6,000 tons to 10,000 tons. 2, in terms of the construction mode, you can consider acetate, tow, filament, filament, such as centralized construction of the project, 3, the production of equipment, most of China's cigarette acetate production equipment has been able to make, individual Key equipment or missing such as curling machine, spinneret, recovery valve and other domestic manufacturing difficulties, the need to introduce, 4, in terms of production methods and control methods, the main use of dry spinning, DCS centralized control system.
In short, acetic acid fiber with excellent performance, wide range of uses, high value-added products, the production process is pollution-free, raw materials can be regenerated, suitable for sustainable development, and China's cigarette acetic acid tow there is still a certain amount of imports, textile production of acetic acid filament yarn is still a blank, completely dependent on imports, therefore, our country should increase the development of acetic acid fiber! Therefore, China should increase the development of acetate fiber!
