There is much room for technological progress

The market outlook is promising

In his remarks, duan xiaoping pointed out that polypropylene is an industry with excellent product performance and green production process. According to the statistics of the national bureau of statistics, from 2012 to 2017, the actual output of nearly 50 enterprises above the scale of polypropylene fiber in China was stable at about 300,000 tons, less than 1% of the total output of synthetic fiber, a variety with a small proportion of synthetic fiber. According to the actual survey and statistics of chemical fiber association, the production capacity of polypropylene fiber in China is 1.036 million tons, and the actual output is about 800,000 tons, among which the capacity of filament (including single silk) is 521,500 tons, the capacity of staple fiber is 240 thousand tons, the capacity of BCF is 119,500 tons, and the capacity of high-strength industrial silk is 1545 thousand tons. Due to the excellent properties of polypropylene fiber, its application in certain fields such as rope, ribbon, nonwovens, geotextiles, eisai, and high-end sportswear, it has maintained a steady development trend in recent years. Due to the historical development track, the industrial development level of polypropylene fiber in Europe and the United States is higher than that in China, especially in the field of industrial use and high-end sportswear. The use of polypropylene in these two fields is different from other chemical fiber varieties, which also makes the polypropylene industry more room for technological progress.

Among them, the President of the unit for guangdong Montana high-tech fiber co., LTD., vice President of units has (in no particular order) : gold new materials co., LTD., zhejiang cixi cable chemical fiber co., LTD., donghua university, college of materials science and engineering, changzhou spirit of special fiber co., LTD., hubei bo towers synthetic fiber co., LTD., jiangxi donghua machinery co., LTD., fujian three macro renewable resources of science and technology co., LTD., qingyuan city YiTong weaving co., LTD. The new President is guo qinghai, general manager of guangdong mengtai high and new fiber co., LTD.

Guangdong Montana is currently focused on differentiation, functional polypropylene filament development direction, on the basis of conventional polypropylene fiber, DTY polyester FDY such, developed a high strength low shrinkage, superfine, profiled, and ultraviolet resistant, anti-aging, antibacterial, flame retardant, far infrared, noctilucent function and differential polypropylene filament, customers throughout Asia, Europe, South America, Oceania, Africa and more than domestic provinces and regions. In the past two years, the company has become the largest producer of polypropylene filament in China, according to the association.

In his speech, guo briefly reviewed the development history of the polypropylene industry. In 1954, he said, ziegler and natta published patents for the manufacture of isotonic polypropylene; In 1957, Italian company first realized the industrial production of isotactic polypropylene; Since the 1960s, Japan has continuously increased investment in the research and development of high-performance, functional polypropylene, vigorously developed the use of polypropylene in decoration and industry, and expanded the application field of polypropylene. In the 1970s, the United States, Italy, the Czech republic and other countries began the development of polypropylene fine wire; In the mid-1980s, concrete strong polypropylene made progress. The United States and Western Europe began to use it in the construction industry. Since the 1990s, with the improvement of the performance of polypropylene fiber, the variety of polypropylene fiber is more diversified. The United States has developed polypropylene fiber with flame retardant, anti-static electricity and other functions, while the western European countries have successfully developed the new differentiated polypropylene fiber such as conductive polypropylene fiber, electric polypropylene fiber, and bioabsorption and degradation polypropylene fiber. By the end of the 20th century, differential polypropylene fiber, such as fine denier, flame retardant, antibacterial, anti-ultraviolet, anti-aging, and far infrared, was developed successively in China, with a certain yield. In the early 21st century, China's industry has further developed high strength, uv resistance, dyeing, fine Dan, super fine Dan and other polypropylene products. So far, most of the differential polypropylene have been produced and developed in China.

At present, compared with large chemical fiber, domestic pp manufacturing is still dominated by small and medium-sized enterprises, and the degree of industrial concentration needs to be further improved. To this end, Mr Guo said: "" we hope to constantly promote and deepen industrial technology exchanges and industry-university-research cooperation with the help of industrial associations as a bridge to promote industrial agglomeration and enhance the comprehensive competitiveness of the industry. Although polypropylene is a small variety of chemical fiber industry, but can have a large role. Polypropylene fiber is also the environmentally friendly industry with the lowest energy consumption and the lowest pollution in all chemical fiber industries. It is a sustainable industry. I believe that with the joint efforts of my colleagues in the industry, and through the continuous development and application of the functions and characteristics of polypropylene, especially the application of the unique characteristics of "acid and alkali resistance", the market prospect of polypropylene industry in the future will be greatly promising.

At the same time, the research on the functionalization of polypropylene fiber in China has entered a period of vigorous development. According to the demand of the production and research of polypropylene fiber industry, the standardization strategy must be implemented. The purpose of conducting polypropylene research is to sort out the requirements of relevant laws, regulations and policies on the construction of projects, including public safety, environmental protection and energy conservation. Understand the total scale (project scale), planning layout, function, performance, key technical requirements and indicators of the project; Understand current construction standards and mandatory provisions analysis, highlight the coverage, feasibility and operability of the existing mandatory provisions; Understand relevant foreign laws and regulations, norms, standards research, comprehensive analysis of regulations, norms, standards elements, terminology connotation, the differences between various technologies and China, etc.; It provides basic data for preparing thematic "research report" and "draft engineering specification".

Guo renqi, research and development director of guangdong mengtai high-tech fiber co., LTD. He pointed out that the technical requirements of lithium battery diaphragm are mainly 6 points. First, the stability of blood circulation, including acid and alkali resistance and corrosion resistance, is stable for a long time in the battery. Second, security, since the temperature about 130 ℃ material closed, integrity of high temperature of 150 ℃ or higher, good insulation; Third, high mechanical strength and stable size; Fourth, the aperture is less than 0.5um and uniform. Five is the void rate in 40~50%; Six is the thickness of certain requirements. The physical properties of polyolefin fiber can meet the above requirements, including good chemical stability, salt resistance, alkali resistance and corrosion resistance. High mechanical strength and stable size; Good insulation; Autistic sex good, low melting point of PE melting point at 122-125 ℃ < 130 ℃; High temperature and good integrity, PP before fully drawn yarn at 170 ℃ still keep good strength.

Huang guofu, general manager of fubang chemical fiber machinery factory in changzhou city, Shared the "current situation of polypropylene equipment and intelligent development Suggestions". He pointed out that at present, China's chemical fiber industry is at the key point of transformation and upgrading, and the transformation from traditional production to intelligent manufacturing, reducing the production cost and human cost of chemical fiber industry is becoming an important direction of technological innovation of chemical fiber machinery, so the development of chemical fiber machinery has attracted much attention. The new equipment can make the production more efficient, more intelligent, and the operation index digitized. The addition of functional masterbatch and the inspection of finished products can be completed online. The products are more diversified, the defective rate of products is significantly reduced, and the fiber quality is further improved and more stable. Intelligent pp equipment can realize automatic material preparation, high-speed spinning and automatic packaging, which can not only solve the problem of high labor cost, low occupation and high efficiency, but also stabilize the quality of finished products, reduce overall cost and increase efficiency.

Li changqi, chairman of jiaxing shengbang machinery and equipment co., LTD., narrates "a method to rapidly upgrade polypropylene spinning equipment to the international level". He analyzed the current situation of domestic polypropylene spinning equipment (filament) : first, a large number of domestic equipment is used, and the equipment is produced by non-mainstream first-line chemical fiber equipment manufacturers. Second, the equipment is old and the technology is low. The hot roller USES steam jacket and multi - stage temperature control technology very few, winding head is basically a rabbit head form. Third, mainstream polypropylene equipment manufacturers basically do not have the high-end hot roll and winding first - class key components manufacturing capacity. Fourth, domestic polypropylene filament equipment technology development is a low gradually to high development process. Fifth, pp filament manufacturing enterprises are eager to get cost-effective equipment.

Li changqi said that around 1995, German and Japanese production of winding head to six (900.920 chuck) eight (1200 chuck) led, hot roller? 220 * 280,? 220 * 350,? 190*350mm long is dominant. The equipment is of higher quality than the equipment currently produced. However, due to its low production capacity and inadaptability to the high production requirements of domestic pet and polyamide fiber market, many of them are discontinued and in the state of being sold. If a large number of idle winding heads and hot rolls produced by Germany and Japan around 1995 are used for dressing and transformation in the polypropylene market, the equipment level of China's polypropylene market will be greatly improved.

In sharing "inventory management and optimization of polypropylene enterprises", huang yangming, technical director of China polypropylene network, pointed out that the inventory data of polypropylene enterprises cannot be updated in real time, manpower cost increases, and customer service quality needs to be improved. Under this background, if we want to do well inventory management, we need to carry out effective operation from three aspects: warehousing, material requisition and warehouse management. In this process, the management of input, sales, storage, and code scanning software is particularly important. Its advantages are: the number of electronic scale generation is directly input into the computer, and the accuracy is high; One-time investment, less labor, low cost, quick results, fast delivery; It can carry rich contents, trace quality problems and improve product competitiveness. Each code carries corporate information, increasing marketing opportunities and influence.
