Prior to this, due to the extremely tight foreign exchange in the country, the domestic textile companies needed only a small amount of imports, and most of the data tested by the company still relied on manual calculation or blackboard comparison. It is the first-generation YG131 dryness uniformity tester developed by Shaanxi Changling Textile Electromechanical Technology Co., Ltd. after digestion and absorption and secondary development. It has ended the history that China cannot manufacture strips. In the 20 years of development, the company has achieved high-tech, high-level and serialization in accordance with the model of “introduction, digestion, absorption and re-innovationâ€, and successfully made the company the largest spinning equipment manufacturing base in China.
The successful model of Changling's development of the dry instrument has brought considerable economic benefits to the people of the country, and it is also a successful reference for the development of innovative and intellectual property systems with Chinese characteristics.
Independent innovation fills the domestic gap
China is a big textile country. Its development and progress are largely due to technological innovation, technological level and equipment level. The predecessor of Changling Spinning Machinery, the state-owned Changling Machinery Factory, is a large-scale military enterprise built during the “First Five-Year Plan†period and one of the country's 156 key projects. Since 1980, the state-owned Changling Machinery Factory has begun to implement the strategic transfer of Baojun to the people. They have fully utilized the military technology advantages and set up research and development, production, and technical transformation services for China's textile industry as the key direction of civilian product development. A textile electronics company that sells in one.
As a standard test instrument necessary for the textile industry, the dry instrument is quite high in precision and complexity. It has been listed as a textile cutting-edge equipment. As of 1986, it could not be produced in China. China is also a big textile country. The demand for strips is large. If long-term dependence on imports is bound to cost a lot of foreign exchange, the road to self-reliance is imminent. To this end, the former Ministry of Textile Industry has made the development of domestically produced strips as a major scientific research project during the “Sixth Five-Year Plan†period and included it in the 38202 research project of the Ministry of Textiles.
In September 1983, Changling Machinery Factory, China Textile Science Research Institute and Shaanxi Textile Industry Company jointly submitted project proposals to the Ministry of Textiles, requesting the development and production of the dry instrument. In January 1984, the joint research and development team commissioned by the former Ministry of Textile Industry to form a joint dry instrument jointly undertaken the development of the instrument. The former Ministry of Textile Industry issued a new product trial plan in (84) No. 2, clarifying that Changling Factory is responsible for formulating the technology introduction and overall design of the instrument, and is responsible for the design, manufacture and final commissioning of the product, as well as localization. jobs. Changling Factory insists on the introduction of one hand and the development of one hand. On the basis of in-depth analysis of foreign products, it draws on its advantages, clarifies its overall design plan, and formulates specific implementation and research plans. They introduced the testing technology of UT-1B type dry meter and a small number of parts from Uster, Switzerland, and combined with the advanced digital processing technology at that time, developed a dry instrument with Chinese characteristics. After three years of research and development, the first domestic dry-line instrument YG131 prototype was born, and the subsequent inspection and assessment work officially began. In early June 1986, the former Ministry of Textiles entrusted a ministerial assessment team composed of Professor Yao Mu, the president of the Northwest Textile Institute of Technology, to conduct direct comparison tests on YG131 and UT-1B prototypes for more than three months at Northwest Textile Institute of Technology. . The test adopts the “up and down stacking†method, and 9 operators are selected from all over the country to collect 15 yarn varieties. The test yarn volume is 180 kg and 5000 tubes, and more than 50,000 data are measured, and hundreds of copies are compared. Spectrogram. After a large amount of data processing, the results of the comparative assessment are finally obtained.
On November 26, 1986, the YG131 strip uniformity meter was officially approved by the former Ministry of Textile Industry and the Ministry of Electronics Industry. The conclusion was that the main indicators such as the CV% value and the spectrum of the YG131 strip uniformity meter reached The level of the UT-1B type dry meter, in addition to the function of the UT-1B dry meter, also has its own characteristics, surpassing the level of UT-1B in some performance and function, in line with the requirements of the textile industry. It can be used in the same way as the UT-1B type dry meter.
The successful development of Changling YG131 dry instrument marks the birth of the first-generation domestic dry instrument, which ends the history of China's inability to manufacture the dry instrument and fills the domestic gap. Its successful development also means that the manufacture of China's textile electronic instruments has begun to enter the ranks of the world's advanced level, solving the urgent needs of China's textile industry. Throughout the development process, Academician Mei Ziqiang and Academician Yao Mu of the Chinese Academy of Engineering have done a lot of work from the program determination and testing of the instrument to the market through identification. The development of YG131 dry instrument successfully condensed the efforts of a generation of Chinese textile and textile experts. Since then, the YG131C type of filament yarn dryer, which is urgently used in the chemical fiber industry, has also been introduced in Changling Factory.
Casting Chinese dry goods brand
The creation of Chinese standards forms a unique production system. In order to better implement the principle of “introduction, digestion, development and innovationâ€, Changling Plant will closely combine the two tasks of digestion, absorption, self-sufficiency and localization, and establish a Chinese metrology measurement standard. .
In 1984, Changling Factory introduced 18 other technical materials at the same time as the introduction of UT-1B dry instrument technology, 46 sets of testing equipment and instruments, uster standard machine, 4 pieces of dry signal standard signal generator (PRG) and special The inspection tools have laid an important foundation for the development of domestically produced dry instruments and the establishment of Chinese metrological instruments. In order to make the measurement standard of China's dry instrument can be issued as soon as possible, at the end of December 1989, Changling Factory participated in the drafting of the "Regulations for the Calibration of the Standard Tester for Capacitive Dryers", which was approved by the Ministry of Textile Industry in November 1992. It was implemented in China in July 1992. At the same time, Changling Factory developed a special signal generator for the dry instrument special inspection tool-YG132 (PRG), so that China has its own instrument for calibration of the dry instrument. Subsequently, the Changling Plant was used as the main unit, and the “Regulations for the Calibration of Capacitive Strips Uniformity Instrument†was drafted. It was approved by the State Bureau of Technical Supervision in February 1995 and implemented in July 1995. Since then, it has formed a standard signal transmission system with independent property rights, and Changling Factory has become the only enterprise in China that has a standard delivery system for the dry instrument.
Continuous innovation to meet the needs of the domestic market. Through the development of the first generation of stems, Changling Textile has profoundly realized that not all technologies can be bought. The real core technology needs independent research and development, and only continuous innovation can continue to develop. Since then, Changling has followed the world's advanced technology and has successively launched the second, third and fourth generation serialization and high-level products, which have become the target of many domestic enterprises.
In the 1990s, in order to meet the user's higher requirements for the detection of yarn uniformity and defect characteristics, in April 1995, a new generation of YG135 series dryers was introduced to the market. For the first time, this series of products applies high-speed signal processing technology and computer technology to the strip uniformity test. It has high integration, good consistency and stability, and has self-checking function. Among them, the YG135CM type dry meter applied to chemical fiber filaments has improved the yarn traction system, can automatically change the roller position, and the YG135G dry instrument pioneered expert system software. The series of products are put on the market in batches, marking the successful birth of the second generation of domestically produced strip uniformity meter products.
With the continuous development of electronic technology, the processing speed of computers has increased dramatically. In January 2002, Changling Spinning & Electric Co., Ltd. first developed the YG136A dry instrument with increased hairiness test function based on the advantages of YG135G/YG136 dry-lighting method. The product uses computer software instead of hardware processing. The signal processing circuit and the data acquisition circuit are integrated, and a new mode of domestic strip processing technology is established. The monitoring software is integrated with the index processing software. The VC high-level language is used to replace the original DSP data acquisition and processing system, which makes the yarn defect processing software, the variation length curve and the spectrum processing software a step. The third generation of dry instrument has greatly satisfied the market demand and has become the representative of the development of domestic dry instrument technology.
Leading the development direction to establish a dominant position in the market. With the continuous development of various new technologies and its in-depth application in textile quality testing, the development of Changling Strip Analyzer has accelerated the research and development of products with independent intellectual property rights with developmental thinking and continuous innovation. In December 2005, the CT2000 automatic strip dryer developed by Changling Textile Electric Co., Ltd. was put on the market. The high-speed automatic features of this product continued to lead the development direction of domestic dry-talk technology, achieving high-speed test of 800 m/min, the first domestic test. Head, automatic yarn feeding system, automatic groove changing and roller automatic reciprocating motion technology, technically fill the domestic gap, compile monitoring software under windowsNT platform, with hairiness test function and fully automatic test spun yarn function. As the fourth-generation dry-hand instrument CT2000 dry instrument representing the domestic advanced level, it is a high-end product of domestic dry-talking instrument with its fast, efficient and fully automatic.
