On March 27, the "14th Five-Year" national key book publishing planning project "A Brief History of China's Chemical fiber" was launched, which recorded the magnificent struggle of China's chemical fiber industry. In the star-studded Chinese chemical fiber enterprises, Yizheng Chemical fiber as the first wonderful appearance of polyester enterprises.

Polyester, is an important variety of synthetic fiber, is also the largest variety, is made of polyester as raw materials by fusing spinning and post-processing fiber, also known as polyester fiber, "Dacron". In the 1970s, "Dacron" once became a popular commodity, which made an important contribution to easing the tension of fabric voucher supply and the outstanding contradiction between grain and cotton.

The construction of the "four chemical fiber" base is the initial battle of China's large-scale development of petrochemical and chemical fiber. In June 1977, the Ministry of Light Industry established the development goal of expanding the second phase of Shanghai Jinshan Project and building an extra large chemical fiber enterprise during the "Five Five" plan of the national economy. Approved by The State Council, Yizheng chemical fiber was included in the national 22 key introduction of one of the projects, the decision operation of Yizheng chemical fiber 530,000 tons/year polyester and polyester project, equivalent to the national chemical fiber production capacity at that time, is a fundamental solution to the people's dressing problems, alleviate the contradiction between domestic chemical fiber supply and demand, change the backward face of China's chemical fiber industry strategic measures.

However, due to the financial constraints of the state, Yizheng chemical fiber project was forced to postpone construction. In order to save this project, Yizheng chemical fiber builders dare to be the first and bold innovation, on the basis of the national advance allocation of 300 million yuan, a total of 700 million yuan of debt loans to domestic and foreign countries, raised the funds needed for the first phase of project construction, and opened state-owned enterprises to "borrow to build factories and operate in debt". This unique way of investment and construction is called "Yizheng mode".

In 1990, Yizheng Chemical fiber I and II projects were fully completed and put into operation, forming an annual production capacity of 500,000 tons of chemical fiber and chemical fiber raw materials, accounting for 1/3 of the national synthetic fiber output, 1/2 of the polyester output, equivalent to 1/8 of the national cotton output, which can provide a set of "Dacron" new clothes for each person in the country every year. Become the largest production base of chemical fiber and chemical fiber raw materials in China.

In 1998, Yizheng Chemical Fiber joined China Petrochemical Corporation as a whole with China Donglian Petrochemical Group Co., LTD., and the advantages of resources, industrial chain and integration were further highlighted.

In December 2000, the State Economic and Trade Commission "ninth Five-Year" major science and technology research project and Sinopec "Ten dragons" science and technology research project - the first set of 100,000 tons/year of domestic polyester device was completed and put into operation in Yizheng Chemical Fiber, breaking the foreign technology monopoly in one stroke, opening up the road of Chinese polyester device construction. It has greatly reduced the technical threshold and investment cost of polyester project construction, and led to the leapfrog development of China's chemical fiber industry.

In 2013, Chen Jinhua, vice chairman of the ninth National Committee of the CPPCC and the first general manager of Sinopec, wrote the article "Thirty Years of Sinopec" on the 30th anniversary of the establishment of Sinopec: In the TV special report of "reporters go to the grassroots", the people in the western region are living a difficult life, eating, living, traveling and using conditions are very poor, but men, women and children are warm and decent clothes.

Over the past 45 years, generations of Yichua employees have used wisdom and sweat, loyalty and dedication to meet the needs of the country and the people as their mission, dare to be the first, work hard, reform and innovation, and forge ahead. Yizheng Chemical fiber has produced more than 54 million tons of polyester products, equivalent to the output of more than 1 billion mu of high-quality cotton fields, and the clothes made from them can add 108 sets of "Dacron" new clothes for each person in the country.

In early 2020, with the outbreak of the novel coronavirus pneumonia and a serious shortage of anti-epidemic supplies, the demand for masks, as the most important protective supplies in the fight against the epidemic, has soared, and it is difficult to find a cover. The "heart" of the production of masks - melt-blown cloth (polypropylene melt-blown nonwovens), the domestic production capacity is seriously insufficient, and the supply is in short supply, which has become the "bottleneck" of the industrial chain.

In order to meet the urgent need to fight the epidemic and protect people's lives, health and safety, Sinopec decided to fully intervene in the production of melt-blown materials, melt-blown cloth and masks. Yizheng Chemical Fiber actively implemented the deployment of the Party Group of the Group company, and on February 24 and March 10, respectively, started the construction of the first phase of 8 and the second phase of 4 melt-blown cloth production lines, with a total production capacity of 6,000 tons/year.

Melt-blown fabric is a "zero basis" project for Yizheng chemical fiber. Under normal circumstances, a production line from scientific research project approval, administrative license approval, equipment procurement and manufacturing to delivery and production, at least one year. "State-owned enterprises have an unshirkable responsibility to meet the urgent needs of the country and society." Yizheng chemical fiber Party Committee issued a mobilization order to the whole company.

Yizheng Chemical fiber was ordered to move, hear the order, start from zero, emergency cross-border, break the routine, wall map combat, set up leading groups, professional groups and party members commandos, design, procurement, manufacturing, construction, production preparation, learning from Huoshenshan, Leishenshan hospital builders, fight speed, all work day and night, orderly development. On March 29, after 35 days, the first production line was completed and put into operation; On May 9, after 76 days, all 12 production lines were completed and put into operation, running out of the acceleration of manufacturing in China, helping Sinopec to become the world's largest melt-blown fabric production base. After all 12 production lines are put into operation, 18 tons of high-quality melt-blown cloth can be produced every day, helping to increase the daily increase of 18 million disposable medical masks.

From the first production line put into operation on March 29 to the end of July, Yizheng Chemical fiber high-quality meltblown cloth was put on the market at parity, targeted supply of national epidemic prevention and protection key enterprises, and implemented the solemn commitment of "SINOPEC let people buy masks and afford masks" with practical actions.

While fully ensuring the supply of domestic melt-blown fabric, since the second half of 2020, Yizheng Chemical Fiber has actively explored the international market, and its products have been exported to Japan, South Korea, Southeast Asia and other countries and regions. The usual medical masks are white, but Europeans like to wear colored masks, if the use of white melt-blown cloth as the middle layer, sometimes there will be defects such as leakage of white. Yizheng Chemical Fiber actively carried out research, through adjusting the formula, optimizing the process and other measures, to solve this problem.

Wearing masks and glasses in winter is easy to fog, which has become a worry for many people. As an important raw material for medical masks, the filtration efficiency and ventilation resistance of melt-blown cloth are a pair of contradictions, and the higher the filtration efficiency of general bacteria, the greater the resistance; The resistance is large, the permeability of the mask is poor, and the breath will leak out from the top of the nose bridge causing the glasses to fog. Yizheng Chemical fiber organization to carry out special research, through the optimization of raw materials, improve equipment, improve filtration efficiency uniformity and other technical innovations, successfully produced ultra-low gas resistance meltblow cloth. This achievement won the first prize for technical innovation achievements of outstanding workers in the national energy chemical geology system.

In mid-December 2022, Yizheng Chemical Fiber quickly responded to changes in market demand, resumed a number of melt-blown cloth production lines, and actively coordinated supply chain enterprises, strengthened quality control, rapidly increased the melt-blown cloth needed for KN95 and N95 masks in short supply in the market, and fully met the order needs of mask enterprises around the country.

In January 2023, Yizheng Chemical fiber used melt-blown microfiber and polyester hollow fiber composite made of new thermal floc successfully trial production, in the case of the same gram weight of the thermal performance increased by more than 30%, expanded the use of melt-blown microfiber in the post-epidemic era. At present, Yizheng chemical fiber is accelerating the development of lightweight thermal tooling in the petroleum and petrochemical fields, creating conditions for workers to operate flexibly outdoors in winter.

45 years ago, Yizheng Chemical fiber dared to be the first and work hard to solve the problem of people's dressing. 45 years later, Yizheng Chemical Fiber for the people's health core cross-border, played a central enterprise "ballast" role.

From June 1 to 2, 2023, SINOPEC successfully held reverse roadshow activities for investors in the whole industrial chain business in Yangzhou and Nanjing. More than 100 investors, analysts and media reporters formed a research group to visit the production line of Sinopec Yizheng Chemical Fiber, East China Oil and Gas, Jinling Petrochemical, Yangzi Petrochemical, Jiangsu Petroleum and other five enterprises, to learn about Sinopec's achievements in integration and collaborative efficiency, transformation and development, scientific and technological innovation and environmental protection.

On June 1, the reverse roadshow activity kicked off in Yizheng Chemical Fiber. At the meeting, Yizheng Chemical Fiber introduced the situation of accelerating the "five transformation" and creating "two bases" with PPT, data and charts. Then, the research group walked into Yizheng Chemical fiber Factory and visited the exhibition hall of scientific and technological achievements of the company. And the PTA project site with an annual output of 3 million tons is under construction.

As a derivative of petroleum, PTA (refined terephthalic acid) connects the two major industries of petrochemical and chemical fiber textile, and is an important part of the aromatic industry chain. As one of the important bulk organic raw materials, PTA can be further processed into polyester fiber, film, plastic products, etc., which is closely related to people's clothing, food, housing and transportation. In recent years, with the progress of science and technology and application development, new polyester products extended by PTA are increasingly widely used in life and health, energy conversion, aerospace, intelligent induction and other fields.

Yizheng Chemical Fiber PTA project with an annual output of 3 million tons is the first set of PTA project with an annual output of 3 million tons of Sinopec, which is an important step for Sinopec to strengthen the aromatic industry chain, expand high-end new materials, and accelerate the construction of "one base, two wings and three new" industrial pattern, and is included in the supervision project of the Sinopec Board of Directors and the key project of Sinopec. The project meets the requirements of the Jiangsu provincial government on improving the industrial chain and strengthening the chain, and is included in the list of major projects in Jiangsu Province in 2021.

Yizheng Chemical fiber annual output of 3 million tons PTA project adopts advanced energy saving and environmental protection and short process technology route, with the advantages of large scale single equipment, green and low carbon. On the one hand, it is conducive to the implementation of the existing two sets of PTA devices of Yizheng Chemical fiber to "free the cage and change the bird", achieve green and low-carbon development, enhance the supporting capacity of Yizheng chemical fiber polyester raw materials, and accelerate the follow-up smart fiber, biodegradable plastics and other new material projects; On the other hand, it is conducive to Sinopec to play the advantages of refining and chemical integration, strengthen and optimize the aromatic industry chain, accelerate the expansion of high-end chemical new materials, and meet the new needs of consumers for a better life.

In recent years, Yizheng Chemical Fiber has earnestly implemented the decision and deployment of the Party Group of the Group company to "strengthen and optimize the aromatic industry chain, promote the upgrading and appropriate extension of the industrial chain", improved the political position, and consciously strengthened the mission of "ensuring the safe development of the aromatic industry chain of Sinopec" with more open ideas, more active actions and more powerful measures. For Sinopec to enhance the competitiveness of the refining and chemical industry chain, play a responsible role, mind to build a "domestic leading, world-class" synthetic fiber and new materials professional company ambitions, always adhere to the people-centered development ideas, gather "devotion-based, to the strivers, not to let honest people suffer" value consensus, leading the majority of employees to seize the day and night, Work hard to accelerate the "five transformation", accelerate the annual output of 3 million tons of PTA and 4 million tons of high-end green new material integration project construction, strive to meet the new needs of the people for a better life, strive to build China petrochemical aromatic downstream industry chain demonstration base and special fiber research and development production base, leading the high-quality development of China's polyester fiber industry, Make greater contributions to writing a new chapter in Chinese modern petrochemical industry.
