During the Tenth Five-Year Plan period, on the basis of mastering the core technology of spandex production, they have invested 900 million yuan to carry out technical transformation and expansion of spandex projects for many times. The technical level is advanced every time, and the technical innovation points are more than once. Self-innovation triumphs all the way: The seventh phase of the project takes the lead in producing spandex with high elongation and low stress by using its own differential technological transformation and capacity expansion technology, becoming the first "10,000-ton class" in China. The eighth phase of the project applied the international advanced continuous polymerization process, the spinning speed was increased from 440 m/min to 800 m/min, and the total production capacity of spandex soared to 6,543,800 tons. The ninth project aims to produce fine denier yarn with high quality and high added value. Advanced continuous polymerization technology, circular tunnel and mechanical false twister are adopted for spinning, reaching the international leading production technology level, and the spinning speed is increased to 1000m/min, so that the total production capacity exceeds 20,000 tons, making it one of the five largest spandex enterprises in the world. Yantai spandex company's independent innovation not only endows spandex products with high-quality connotation, but also holds up many dazzling auras, and honorary titles such as national key new products, Shandong famous brand products and China famous brand products follow one after another. At this point, Yantai spandex company has realized the development of spandex products from "no one has me" to "people have me strong" and successfully completed its own one-legged jump. Leap: Meta-aramid realizes industrialization.
With the acceleration of innovation, breaking through the single product structure has become the new pursuit of Yantai spandex company. The prominent position and important role of meta-aramid fiber in the world's high-tech field has attracted great attention from the company's decision-making level.
Meta-aramid fiber is a kind of special synthetic fiber with high temperature resistance, flame retardancy and insulation, commonly known as "fireproof fiber". For a long time, only the United States, Japan and the former Soviet Union monopolized the production of meta-aramid fiber, and the technology was top secret. These products are regarded as important strategic materials and are strictly controlled. Yantai spandex company invested more than 20 million yuan in five years and was built in 2002 after repeated tests.
Become a stable and continuous pilot production line. After the success of the pilot test, the company's decision-making layer decided to invest 654.38 billion yuan to develop the industrialization technology of meta-aramid fiber after many demonstrations. After two years' efforts, the industrialization technology of meta-aramid fiber was finally developed and successfully industrialized in May 2004. All technical performance indicators have reached the international advanced level, making China the fourth country in the world to mass-produce aramid fiber after the United States, Japan and Russia.
In order to survive, enterprises must have core technology and scale advantage under core technology. For this reason, Yantai spandex Company, on the basis of summing up the previous construction experience of meta-aramid fiber, has carried out two expansions, greatly adjusted the equipment and technology, and greatly improved the product quality, with an annual production capacity of 2,800 tons, surpassing Teijin Company of Japan and becoming the second largest supplier of meta-aramid fiber in the world. At present, the market share of "Newstar" brand meta-aramid fiber in domestic high-temperature filter materials reaches 60%, and the fire-fighting clothing processed with aramid colored yarn has begun to be systematically equipped with forest police and fire-fighting forces in China. In addition, aramid products are also exported to Europe, the United States, Japan, South Korea and other developed countries and regions, and the company is included in the scope of suppliers by the US military. At this point, Yantai spandex company has realized the transformation from single product to multi-product and successfully completed their leap. Years of innovative practice have cultivated a research and development team with high technical level and strong combat effectiveness, which has reserved strong strength for the world's special fiber technology peak.
Aramid paper is a special paper made of pure meta-aramid fiber, which has excellent properties such as high strength, low deformation, flame retardancy and insulation, and can be used to make electrical insulation materials, honeycomb structure materials and heat insulation and flame retardant materials. This year, Yantai spandex Company will invest more than 80 million yuan to build an aramid paper project. At present, the project construction is in progress, and it is expected to be put into production early next year to fill the domestic gap.
Para-aramid fiber is a high-performance fiber with high strength, high modulus and high temperature resistance. It has the reputation of "synthetic steel wire" and can be processed into body armor, aircraft shell, cut-resistant protective gloves, submarine cables and so on. It has broad market prospects in the fields of national defense, information industry and automobile industry. Yantai spandex company's pilot project of para-aramid fiber was included in the major science and technology special plan of Shandong Province in 2004. More than 50 million yuan will be invested in the pilot project construction this year, and it is expected to be put into trial operation early next year. This project will fill the domestic gap, break the monopoly of DuPont and Teijin, and play an important role in promoting the development of China's aerospace and national defense industry.
Yantai spandex Co., Ltd. will complete the last action of this round of independent innovation triple jump-double-foot take-off on aramid paper and para-aramid paper. We are convinced that Yantai spandex company, which has the advantages of talent technology, market network and brand influence, will be more exciting in the future.
