Because polypropylene is not easy to color in the conventional dyeing process, it did not occupy an important position in the textile field in the past. However, now the method of dyeing with the original solution is adopted, which has excellent dye fastness and washing resistance, which opens up a very wide range of applications, such as sportswear, car interiors, etc. Especially the automobile industry uses a lot, because the automobile industry relatively needs fewer colors. Facing these markets, the spinning machine not only can provide high-quality fibers, but also can change the variety easily and reduce waste silk, and it must be able to spin some special fibers. These requirements are summarized as cost-effective production; high mechanical efficiency, low maintenance rate, and long component life; stable high-quality products; wide product range and flexible operating windows, which can quickly change varieties and waste Less silk; several different products can be produced at the same time. Timely meet market demand; easy operation and good production reproducibility.
　　Answer: The design idea of ​​the new machine. The new process methods and equipment of Lunqing viscose fiber. In the current slow-developing and low-priced market, most viscose staple fiber producers are looking for innovative methods. Process and equipment to reduce costs.
　　I kind of name is 53, and the new technology and equipment developed by Lunqing Company are introduced to the market for this purpose. The main advantages of this system are higher production; improvement of production capacity and quality parameters. Environmental considerations, increased labor productivity and reduced production costs are very important for the renovation of existing factories and the investment and construction of new factories. Barmag is committed to the new technology of polyester filament! Before 0, the method to improve labor productivity and economic benefits in spinning production was still to increase the spinning violation and expand the spinning position. The latest winding; head technology has achieved a winding rod length of 150, with each spinning position! More than ten nozzles. The size and weight of chrysanthemum are increased. In addition, it is still trying to increase the spinning speed of polyester 1 to 5000 meters, usually this requires some physical and chemical improvements to the polyester polymer. ! In addition to the polymerization modification method, 3! Shen 1 spinning process is another way to make the spinning speed reach 5000 m min without polymer modification.
The new type of synthetic fiber produced by the gel spinning method is based on the research of a new type of 1. Polyvinyl Alcohol Fiber Melon by Crowley, a food compress company. In 1998, due to the use of a new spinning process, that is, wet The cold gel spinning method uses organic solvents, a variety of 3 polymers can be spun, and the fiber structure is uniform. Some properties, such as high-strength bath water and separable peeling, are unique. 3 In the early stage of scientific research, the molecular weight of 13 and the solvent were studied. After that, 3 was used. Gel imitation silk 1 led to 7 ultra-high strength. 2.9, ultra-high molecular weight inner six fibers.
　　 In the process of commercialization, cold gel spinning method and 0 and 30 methyl sulfite were selected as solvents, and in many polymers, good fibers were obtained. The advantage of this spinning method is that there are many varieties of raw materials, such as PVAPAN. The fiber push structure is uniform, high strength, good spinnability, high productivity, and water-soluble skewer is produced.
Based on years of experience on polyester and nylon spinning machines, Barmag provided a new generation of polypropylene filament spinning machines, which are designed and modified according to the requirements of polypropylene using reliable components on polyester and nylon spinning machines. .
The spinning line is completely arranged vertically, that is, the extrusion spinning, drafting, winding melt and the filament travel vertically from top to bottom, and the guide wire and turning point are reduced to a minimum, so as to achieve high speed and fewer ends. , The polymer is melted in a 300 screw extruder, the geometrical size of the screw is specially designed for polypropylene, and the controlled melting temperature and conveying volume are very accurate.
　　The melt pipeline and the spinning box are not electrically heated but use a kind of heat transfer oil, so that the temperature of the entire system is absolutely constant, thus ensuring the quality of the silk.
The layout of the melt pipeline is optimized so that each melt channel is equal, and the conditions of each spinning position are the same, so the quality is also due to the description of 3. The system can feed the masterbatch or other additives to each spinning individually. Bit. Each 3 is equipped with a screw extruder to transport additives, and there are metering pumps at each spinning position. , The 300 mixer of the AC pump makes the two melts best mix to achieve uniform color diffusion. The greatest flexibility of this system is that it can control the metering and conveying volume of each spinning position, so that it can spin deniers and varieties of different process parameters.
　　Self-sealed bottom-loading spinning assembly to ensure that the flow rate and temperature of the body are the same. The side air adopts a horizontal form to cool the silk uniformly, and the Uster of the silk is excellent. At the same time, monomer suction reduces the amount of condensation of monomers and oligomers. The heating roller can reach a speed of 7 meters, with a large drafting force, and the bearing has a long life. The high-frequency heating system is divided into 6 heating zones to make the temperature uniform and the temperature difference is less than 1.5.
　　The winding head equipped with wing-type reciprocating device is very wear-resistant, and the angle of the thread can be freely selected to meet the requirements of high-speed winding and bobbin forming. Since the reciprocating transmission is separated from the main transmission, the traverse reciprocating angle can be changed during the winding process, so that it can be adjusted to prevent overlap without affecting the high water absorption polyester yarn. Japanese polyester fiber manufacturer Toyobo Co., Ltd. developed the energy The polyester filament absorbs sweat and discharges it. It is a kind of desiccant added in the manufacturing process.
　　 An independently developed and produced acrylate powder is added to the polyester molecule, which increases the water absorption capacity of the material by about 3 times, which is about twice as high as that of cotton. From September 2000, Toyobo will sell products to apparel manufacturers, first in the spring of 2001! For the 13-brand sportswear, the sales plan of Toyobo in the 2002 fiscal year will reach 2.6 billion JPY and USD 25 million.
　　The Federal Trade Commission, the world leader in polypropylene resins, has cleared the obstacles to the merger of 310, 81, Royal Dutch Shell and 863, BASF Polyolefins. The new 5050 joint venture project was approved because it met the requirements of the European competition authority. Its name is the Netherlands, 5 such as 4 cities, 5050 Shell and BASF and Ding, 00 BASF will merge into the joint venture, thus forming the world's largest polypropylene producer, with annual sales of 6 billion US dollars.
　　833 will be the world's largest polypropylene and polyethylene producer. It has 20 production bases in Europe, Asia and the Americas and employs approximately 10,000 people. 838 hopes to make at least 100 million U.S. dollars in profit in the joint.
　　 Dr. Juegen, Chairman of the BASF Board of Directors, said that this is the beginning of BASF's forward-looking strategy in the plastics field. Combining the two heavyweight market players will mark a breakthrough in the use of effective and economical production methods and market structure for innovative products. The chairman of 13; said that we will continue to provide high-quality products and solutions for users. We hope that 8 Ying will become the world leader in the polypropylene market.
　　 The tension of the silk. The method of using downstream silk capture therefore has a higher transmission rate.
　　 According to different needs, there are two design schemes for drafting, and the strength of each drafting zone can reach 3.5 and 4 grams denier. This kind of yarn can meet the requirements of a very low textile shrinkage rate. The medium-strength yarn can be used in a wide range. Depending on the polymer, a higher denier or a higher strength of 7 g denier can be obtained at a lower speed. If the normal speed of the equipment is used, the resulting silk strength is slightly lower by about 5 g denier.
　　The process achieves high speeds so that the full draft yarn speed can reach 4500 meters or higher. This has been achieved on the Barmag production line, and standard polymers and conventional masterbatches can be used. The difference between polypropylene and polyester and nylon is how to solve every detail of the production and try to optimize it, so as to get perfect. However, polypropylene is the opposite. In the past, it was only produced on small equipment without much optimization research. Now use polyester and nylon textile machine parts to improve, and use ordinary polypropylene raw materials to get high-speed spinning effects. The main characteristics of this spinning machine are vertical mechanical layout, linear raw material flow, and flexible and variable machines. Configuration, the controllable uniform temperature in the spinning box; the mechanical components can adapt to high spinning speeds and have potential; the operation is simple and the operation can be performed.
　　 Since the optimized polypropylene operating parameters are integrated, the standard gains can be achieved. Now the labor productivity of polypropylene fiber is completely comparable to that of polyester and nylon, and the cost is low, and the higher secondary investment can be quickly recovered.
　　 spinning machine can be used for small-scale production and large-scale production line, so it can be produced in large quantities, and can also be used to produce a small amount of special varieties for the market.
　　The recovery and improvement is expected to start from the key 4 in the middle of the production chain, and to establish a price chain and strive to get rid of the connection with consumer products. This means an important change in price adjustments. In the Asia-Pacific region, due to a better balance between supply and demand, this is the key to profiting parabenzoic acid.
　　Western Europe will form an integrated polypropylene production and operation. Ten European petrochemical companies have agreed to establish an integrated polypropylene production network in Northwestern Europe. Bayer 8, 88 people 0, 0 Amoco Celanese, 0 six 0 which 38, this 05 river 0 1 India 301 is also 886 scared 8 Tun 6 Dai, 13, 61, etc. are all suspected producers and users of polypropylene. They have already begun to plan to implement the so-called. This is a joint production line connecting the Cologne and Ruhr regions in Germany and the Rotterdam 76 India region in Helan. In order to prepare for the finalization of the line in mid-2001, the company Er, 0, came to engage in this work.
