When Mei Ziqiang returned to China in 1958, it was at the climax of the "Great Leap Forward", when high-speed spinning tests swept across the country. The Ministry of Textile Industry organized a working group, Mei Ziqiang as the Institute of Textile Science carding group leader, the main person in charge of the working group, and the Institute, Qingdao Spinning Machine Factory, Shandong Textile Research Institute of technicians, in Qingdao, China's cotton four factories to carry out high-yield carding machine research. In the Ministry, the leadership of the hospital attention and personal involvement, research, design, manufacturing and production of all aspects of the use of personnel work together, day and night, the newly designed 1181E card in June 1959 in Qingdao, China, passed the identification of five plants and batch production. Its prototype participated in the International Textile Machinery Exposition, attracted the attention of international counterparts. After the identification of the machine, the Ministry of leadership decided in Qingdao State Cotton Factory, Shandong Weifang Cotton Spinning Factory, Henan Huaxin Cotton Spinning Factory large-scale production tests. Mei Ziqiang for the large-scale production test problems exposed, one hand to improve and enhance the study of automatic dust absorption, fault automatic stop, large rolls and automatic tube change measures, and in May 1961 in Qingdao cotton five plant held a card three automatic experience exchange symposium; the other hand to grasp the process test, in-depth study of the laws of high-speed and high-productivity card. 1961, a number of improvements made in the design and manufacturing In 1961, in the design and manufacture of a number of improvements in the design and installation of an automatic dust-absorbing system of 20 sets of prototype, changed to the Shanghai State Cotton Factory to continue the production test, the end of 1963 and the beginning of 1964 has been carried out in the mechanical appraisal and process appraisal, affirmation of the direction of the high-yield and the main measures to make it clear that there are problems. 1964 in February, the working group to the Ministry of Textiles leadership report on the test in Shanghai, decided to design and manufacture of a new prototype. 1965 September. The use of four roller stripping two A185 card in Shanghai cotton factory passed the appraisal, and put into mass production, the output from the original 5 kg to 15 kg. May 1966, after another improvement of the A186 high-yield card in Qingdao cotton factory passed the appraisal organized by the Ministry of Textile Industry, and formally put into mass production, the output of 25 kg per hour.
1958-1966 years, high-yield card research from small pilot, pilot to large-scale production tests, test work from Qingdao to expand to Shandong, Henan, Zhejiang, Shanghai and back to Qingdao, three times to significantly modify the design, three times to manufacture new prototype, and finally make the domestic carding machine hourly output reached the then international advanced level. Cotton spinning mills with 10,000 spindles of fine yarn with carding machine from 48-50 units reduced to 16-18 units, a substantial savings in investment and labor, and achieved great economic benefits.
In conjunction with the experimental research work of high-yield carding machine in the past few years, Mei Ziqiang and the group published a series of papers. High-yield card on the various new technical measures in the old machine transformation has also played a good guiding role. Switzerland Uster company produced the dryness uniformity meter, as early as the 1940s was used by national textile mills to detect sliver, roving and spinning yarn dryness unevenness. 1949, Uster statistical values began to provide different spinning systems sliver, roving and spinning yarn unevenness of the world level of comparative values. Spinning mills used these statistical values to measure the gap between their products and the world level, and yarn users used the statistical values to evaluate the quality level and suitability of yarn. Strip uniformity has become an internationally recognized main index for evaluating yarn quality. China began to develop the strip drying instrument in 1950s, but failed to succeed. Since the reform and opening up, the textile products enter the international market in large quantities, but the spinning mill is in urgent need of the dryness meter can only rely on imports. 1981 October, in the Ministry of Textile Industry Production Division held the electronic yarn clearer use of experience exchange meeting, Mei Ziqiang suggested Shaanxi Changling Machinery Factory to give full play to the military industrial enterprises in talent, technology, development capabilities, quality assurance system and other aspects of the advantages of the development of dryness uniformity tester. Changling Machinery Factory accepted this suggestion and discussed the development plan with Mei Ziqiang for many times. in October 1982, Mei Ziqiang emphasized the work of the Research Institute, and after the consultation, he took the lead in organizing the cooperation between the Research Institute and Changling Machinery Factory, absorbing the advanced technology from abroad, and developing the home-made strip dryness tester to replace the imported one. Changling Machinery Factory also hired Mei Ziqiang as the general technical adviser of the factory's "high-precision textile electronic instrument development and production base". The development of the homemade strip dry uniformity meter was included in the Ministry of Textile Industry "Sixth Five-Year Plan" to tackle the trial production of new products, and in July 1984, the review of the overall design program, the development of a full-fledged.
In order to ensure that the performance and main technical indexes of the domestic drying instrument reached the level of the Uster drying instrument, Mei Ziqiang went to Changling factory three times to improve the overall design program. After three years' hard work, the domestic YG131 strip drying uniformity tester passed the appraisal jointly organized by the Textile Machinery Corporation of the Ministry of Textile Industry and the Radar Bureau of the Ministry of Electronics in November 1986, which considered that the strip drying tester had good testing accuracy, stability and consistency, strong anti-interference ability, high degree of automation, and reached the international advanced level at that time.The YG131 strip drying uniformity tester won the award of Outstanding Achievement of Technological Development of State Economic Commission in 1988, and was awarded the prize of Outstanding Achievement of Technological Development of State Economic Commission. YG131 type strip uniformity tester was awarded the prize of excellent achievement in technology development by the State Economic Commission in 1988, and the second prize of National Scientific and Technological Progress in 1990.
In 1964, the Ministry of Textile Industry set up a working group for the selection, design, trial production and appraisal of new cotton textile, printing and dyeing and knitting equipments in Shanghai, concentrating on the development of domestic complete sets of new equipments.At the beginning of 1965, the Ministry of Textile Industry decided to build a cotton textile model factory with 50,000 spindles and 1,500 looms. To this end, the second generation of domestic A series of new equipment for cotton spinning in June 1966 installed in the Institute of Cotton Spinning Experimental Workshop. Mei Ziqiang was appointed to be responsible for the cotton spinning new equipment for one-stop production test, for the construction of Sanmenxia Huixing cotton spinning model factory and for Tianjin and Hebei to undertake foreign aid projects to prepare. After the beginning of the "Cultural Revolution", the leaders of the Research Institute were sidelined one after another, and it was difficult to carry out the experimental work. Mei Ziqiang by all means, from Tianjin and Shijiazhuang to foreign aid engineers and technicians, and from the Huixing Cotton Spinning Factory borrowed a group of workers, only to complete a production test, accumulated a set of process data, and put forward the improvement of equipment. As a result of foreign aid projects in urgent need of this equipment, in October 1968, Mei Ziqiang and the Ministry of Mechanical Bureau of Yang Bingxun, Ma Debang was ordered to form a three-member team, convened by this set of equipment, the host plant's technical staff with the expansion of the production test to go to the Huixing Cotton Mill, to further test the performance of the equipment, in order to minimize the difficulties of the project and the failure of the foreign aid.
Hui Xing Cotton Spinning Factory's expanded production test is the same in the anarchy, leadership and command failure of the situation, living conditions are very difficult. Mei Ziqiang or do their best to overcome the difficulties, completed the test task, for this set of equipment to accumulate the quality of the process, suitable for spinning varieties, as well as maintenance management and other aspects of experience, and the spinning machine factory put forward a series of improvements in the design, improve the quality of processing and manufacturing of the comments and suggestions. In May 1975, Mei emphasized back to Beijing, participated in the organization and leadership of the Ministry of Light Industry, Textile Industry Bureau in the country's new cotton spinning mills to promote the activities of the Anlu experience, in stages and batches of study classes to carry out the cotton textile production "3850 on the level of the level" activities to help enterprises around the world to reach the Ministry of the first grade level: cotton yarn folding 20 count thousands of spindle hourly output 38 kilograms or more, yarn thousands of spindles with less than 50 broken heads, cotton yarn first-class first-class rate of 96% or more, pieces of yarn cotton consumption of 193.5 kilograms or less. From 1978 to 1980, we focused on helping 122 cotton spinning mills, which accounted for about 1/3 of the national cotton spinning production capacity at that time, with a total of 5.56 million spindles, to improve the level of production technology and management. Increased production of cotton yarn is equivalent to the production capacity of the new 500,000 spindles, and contributed to the completion of the national cotton production tasks.
In 1987, the Ministry of Textile Industry set up a science and technology committee, Mei emphasized science and technology appointed executive deputy director, presiding over the daily work. The party group of the Ministry of Science and Technology Committee was established in the decision clearly stipulates: Science and Technology Committee is under the leadership of the Minister, the development of science and technology in the textile industry guidelines, policies and major scientific research issues for consultation, staff organizations. Mei Ziqiang in the Science and Technology Committee work for more than ten years, seriously implement the decision of the party group of the Ministry, combined with the situation and tasks of the textile industry at all stages, investigation and research, for the revitalization of the textile industry advice. In view of the important role of automatic winder in improving product quality and labor productivity, and in view of the several ups and downs in the development of China's automatic winder and the difficulty of passing the test, he put forward the "proposal on accelerating the technological transformation of China's winder" and published the "trend of the development of foreign winding technology and the technological transformation of China's winder". In 1992, the Ministry of Textile Industry formed an expert evaluation group for the automatic winder project, with Mei Ziqiang as the head of the group. Evaluation group put forward the "automatic winding machine and shuttleless loom introduction of technology and localization of the overall program" of the assessment of the argument for the introduction of technology to provide a basis for decision-making on localization.
Cotton is the main raw material for textile production. 1980s, China's cotton production ups and downs. State to promote cotton production, several consecutive substantial increase in the purchase and supply prices of cotton, increasing the production costs of textile enterprises, affecting the export of textile products, cotton textile enterprises gradually fell into difficulties. 1990, Mei Ziqiang went to Xinjiang to visit the development of cotton production in Xinjiang has unique favorable conditions, he put forward the "on the support of Xinjiang to accelerate the development of cotton production recommendations". Development of cotton production recommendations. Suggested that "from the policy, funds to support Xinjiang to speed up the development of cotton production, Xinjiang to build China's stable cotton production and supply base". He also put forward proposals to adjust the layout of the national cotton planting areas and accelerate the reform of the cotton production and management system.
The end of the 1990s, China's textile industry after the pressure spindle reorganization, has entered a new period of structural adjustment, promote industrial upgrading. Mei Ziqiang and timely put forward "on the transformation of traditional cotton textile industry with high-tech proposals" and "on the comprehensive assessment of new domestic cotton spinning equipment, technical and economic performance and summarize the use of management experience," in order to adapt to the large-scale technological transformation of the cotton industry, to help enterprises use the new generation of cotton spinning equipment. To help enterprises use a new generation of new equipment for domestic cotton spinning. Mei Ziqiang also took the lead in organizing the Academic Committee of the Chinese Textile Engineering Society under the professional committees of the current situation of China's textile industry, the contradictions and problems faced by the international textile science and technology trends, our gap, the direction of China's textile science and technology development of various industries and countermeasures to carry out research, respectively, in 1990 and 1997 to write and publish the "textile industry", "the Eighth Five-Year Plan", "the textile industry". In 1990 and 1997 respectively, the company prepared and published the "Eighth Five-Year Plan" and "Ninth Five-Year Plan" textile science and technology development strategy study, which was welcomed by the relevant departments and engineers and technicians around the world.
Mei Ziqiang as a member of the Eighth and Ninth National Committee of the Chinese People's Political Consultative Conference (CPPCC) during the *** put forward more than 10 proposals related to the development of the textile industry, including the second meeting of the Ninth on the "proposal to take further measures to save the silk industry" proposal by the Committee on Proposals to pay attention to the convening of the special consultative forum, the State Economic and Trade Commission's response to the proposal. The reply of the State Economic and Trade Commission to the proposal put forward three points of view, such as strengthening product development, exploring domestic and foreign markets, and promoting the reform of trade, industry and agriculture integration. The proposal was also selected as the outstanding proposal of the Ninth CPPCC. In May 1988, the Chinese Textile Engineering Society held the 19th Congress, Mei Ziqiang was elected executive director and director of the Academic Committee. Mei Ziqiang presided over the academic work of the Society, the Society's older leaders Chen Weiji, Du Yansun, etc. as an example, to learn from their noble character, inherited their excellent academic style, and actively organize and carry out various forms of academic activities.
He establishes and improves the organization of the professional committees under the Society, plays the role of the academic groups under the professional committees, and carries out multi-level and multi-form academic exchange activities. Mobilize the majority of engineers and technicians to summarize the exchange of production technology experience, and promote the technological progress of the textile industry. Mei Ziqiang over the years to lead the cotton textile committee to organize and carry out combing combing machine, metal needle cloth, rubber rollers rubber ring, air twister and 1332-type winding machine technology transformation and other academic exchange activities, have received a better effect by the manufacturing plant, production plants and the relevant scientific researchers welcome.
In order to commemorate Chen Weiji for the textile industry and textile engineering society development and construction of outstanding contributions, the 19th Congress of the Chinese Textile Engineering Society decided to set up Chen Weiji excellent thesis award, every two years. Mei Ziqiang served as the director of the jury. As a result of adhering to the selection criteria and conditions, continuously broadening the channels for soliciting papers, and improving the methods for recommending and selecting papers, the Chen Weiji Excellent Paper Award and selection activities have been valued and supported by local societies and engineers, and have become an influential academic activity of the Chinese Society of Textile Engineering. The Third National Congress of the Chinese Association for Science and Technology (CAST) decided to prepare and publish the Biographical Sketch of Chinese Experts in Science and Technology. According to the deployment of CAST, China Textile Engineering Society set up the editorial committee of textile volume in November 1992, with Mei Ziqiang as the director of the editorial committee. After more than three years of efforts, the first volume of the textile volume was published in March 1996 by China Textile Press. Shortly thereafter, Mei Ziqiang began to organize the textile volume 2 compilation work.
Beginning in 1997, the Hong Kong Mulberry and Flax Foundation commissioned the Chinese Society of Textile Engineering to select the Mulberry and Flax Textile Science and Technology Award, and Mei Ziqiang was responsible for the selection work. This award is selected once a year, and has played a positive role in stimulating the cultivation of outstanding young and middle-aged talents and promoting the development of textile science and technology.
Since 1988, Mei Ziqiang and other leaders of the Textile Engineering Society together organized a number of large-scale academic activities. For example, in early 1990 in Beijing, the National Annual Conference, there are more than 200 experts from all over the country to the meeting, more than 90 papers selected for the development of the textile industry, "Eighth Five-Year Plan" science and technology development plan provides a lot of reference value of the information. In April of the same year, also organized and held in Shenzhen, the International Coating Application Symposium. 1999 November, Mei Ziqiang solicited the Chinese Academy of Engineering Department of Agricultural, Textile and Environmental Engineering and the State Textile Industry Bureau of the Department of Planning and Development and the China Association for Science and Technology's support for the convening of the "Twenty-first Century Youth Forum - - High-tech transformation of the traditional textile industry academic forum.
