Chinese Printing and Dyeing Lead from Lag

Fabric dyeing and finishing equipment lags behind in the entire textile industry. The reason is that the dyeing and finishing technology and equipment of fabrics are in a state of lag for a long time, and they also have some difficulties that are difficult to solve. First, there are many fabric dyeing and finishing processes, including mercerizing, sizing, batik, corrugation, calendering, lapping, stone washing, laundering, linting, discounting, and crimping, etc. There are many links, and the quality factors of the printing and dyeing process, management, and personnel also have some influence. The second is that printing and dyeing fabrics are closer to the market, close to the consumer, the market and the transient of consumption, the variety of fabric colors should keep up, the lag and need of process technology and mechanical equipment will also be long-term, if the processing is good, the lag interval The cycle may be shortened.

In this context, as early as November 26, 1997, the former China National Textile and Apparel Council reported to the State Economic and Trade Commission the proposal proposal for the “New Type of Dyeing and Finishing Equipment and Process Technology” project. This project received the support of the state. The State Economic and Trade Commission entrusted China International Engineering Consulting Corporation in February 1998 to conduct the assessment. Subsequently, China International Engineering Consulting Corporation organized relevant departments and experts to conduct research on printing and dyeing enterprises in Zhejiang, Shanghai, Jiangsu, and textile machinery enterprises in Shanghai, Jiangsu, Zhejiang, Hunan and Hubei, and in July 1998. The argumentation meeting was held successively and the demonstration assessment report was written. The China Textile Association compiled the supplementary report of the project according to the demonstration. The State Economic and Trade Commission quickly approved the implementation of the project.

The proposal and the main content of the project is based on the key and weak links of the printing and dyeing and finishing technology at that time, including the high-efficiency steamer in the new type of cotton, polyester and cotton dyeing and finishing equipment, retort bleacher, pre-shrinking finishing machine, and heat setting machine. , Servo drive flat screen printing machine, magnetic bar type rotary screen printing machine, intermittent dyeing machine, automatic color adjustment system and other special items. Synthetic fabric dyeing equipment in the refiner, wrinkling machine, alkali reducer, loose washing and drying machine. Rollers, rubber rollers, edgers, and weft-insertion devices in general-purpose and general-purpose devices.

In the research and implementation of this project, the policy of combining production, study and research was implemented. The project has singled out the technological test and cooperation units, including the research and experimental units of universities and colleges such as China Textile University, China Textile Academy, and Changzhou Dyeing and Printing Machinery Experimental Center. At the same time, it also considers the use of printing and dyeing machinery and equipment after the successful development of the use of units, including the production of cotton, polyester-cotton, apparel fabrics and production of chemical fiber simulation fabrics of technological transformation.

The printing and dyeing and finishing machinery production undertaking unit in the project, according to the company's conditions and the original division of labor, respectively by the Huangshi Textile Machinery Plant bear high efficiency desizing pretreatment machine, continuous pad dyeing machine, hot melt dyeing machine and magnetic cylinder type circular net Printing machine. Zhengzhou Textile Machinery Factory undertakes a shrinking finishing machine, and Shaoyang No.2 Textile Machinery Factory undertakes a heat setting machine, a roll dyeing machine, a flat loose-type scouring machine, and a flat loose-type alkali reduction machine. Shanghai Printing and Dyeing Machinery Plant undertakes a retort bleaching machine. Servo drive flat screen printing machine, large capacity jigger is undertaken by host production companies such as Hangzhou Dyeing and Finishing Machinery Equipment Co., Ltd., and automatic pulping system is produced by Shenyang No. 2 Textile Machinery Factory; general components and special components for textile machinery The cloth roll was separately undertaken by the Huangshan Textile Machinery Factory in Kunshan; the rubber roll was undertaken by Wuxi Erbi Rubber Co., Ltd.; the electric and pneumatic edgers and the optoelectronic full-wielding device were undertaken by Changzhou Textile Instrument Factory and Taicang Textile Instrument Factory respectively. The use of process equipment is based on the type of fabrics and relative to the printing and dyeing and finishing machinery manufacturing enterprises, which are respectively Changzhou Printing and Dyeing Machine Experimental Center, Wuxi Pacific Group Corporation, Wujiang Craft Manufacturing Plant, Hebei Ningfang Group and Jiangsu Bayi. Printing, dyeing and weaving group undertakes. The entire project consists of 15 units. The technological transformation of these units was integrated into this general project and received state funding and funding. When this project was applied for, including technical development and technological transformation, the total investment quota was revised, demonstrated and assessed, and the country's comprehensive balance was adjusted several times. The total investment officially released was RMB 198.9 million.

This project has two characteristics. First, the products developed are targeted, and they are all key process technologies and equipment that address the needs of the textile printing and finishing market. The second is the close integration of the research and development of machinery and equipment, and the use of printing and dyeing technology, which has achieved immediate results.

Through the implementation of more than two years, this project has achieved gratifying results and produced good corporate and social benefits. High-efficiency washing, steamer washing and high-feeding units in high-efficiency desizing and pretreatment facilities have been improved with new improvements; uniform rolling mills, reduction steamers, bake machines, and new-type pad dyeing machines in continuous pad dyeing machines. Efficient evaporating and bleaching machine has been adopted by Hebei Ningfang Group. The specifications of magnetic bar rotary screen printing machine have achieved 12 sets of colors and 16 sets of colors. The large-capacity jigger has realized the requirements of constant tension and constant speed limit. Flat pine loose base reducer, to meet the user's satisfaction requirements. General-purpose devices and special-purpose basic parts include optical full-width weaving, cloth guide rollers, and edge suction devices. After the unit's efforts have been implemented and the technology is solved, it is matched with the host to meet the host requirements.
