　　The development of printing and dyeing industry, without the support of the textile machinery industry of course not. In the early days of the founding of the People's Republic of China, China implemented the policy of organization, key breakthrough, overall design and complete production, and began to manufacture its own complete printing and dyeing and finishing production lines. Later, it gradually improved, improved, and improved, and then improved.

　　Compared with cotton textile machinery, printing and dyeing machinery foundation is relatively weak, only a few private enterprises in Shanghai in the early days of the founding of the People's Republic of China have some printing and dyeing machinery production, but the climate. However, at that time, there was a favorable condition that could be developed. That is, some printing and dyeing enterprises in coastal areas such as Shanghai, jiangsu and zhejiang had imported printing and dyeing equipment, which was still in operation and could be used for reference.

　　With such a foundation and a group of scientific and technological personnel familiar with printing and dyeing technology and equipment manufacturing, such as li chuanlu, ni wenlin, zhu dihua and xu tiehua, whom I came into contact with at that time, China soon organized the design and manufacturing of printing and dyeing and finishing complete sets of equipment.

　　Coincidentally, at that time, the raw material of cotton textile is mainly cotton, cotton production to a large extent depends on the weather. Cotton production seems to have a law, double harvest, single year yield. When harvest textile machinery enterprises full of production tasks, when the lack of harvest textile machinery enterprises downsizing, shutdown, training. In 1955, cotton textile machinery production, textile machinery enterprises have surplus production capacity. Textile machinery design company including the Shanghai office, a large number of technical personnel mapping design of printing and dyeing machinery drawings, technical data, mainly zhengzhou textile machinery factory, Shanghai printing and dyeing machinery factory and other textile machinery factory as a subsidiary division of labor, began to produce printing and dyeing and finishing complete sets of equipment. Before starting singeing machine, to processing, mercerizing, dyeing and printing until finishing rolling, folding, light packaging, took more than a year of time, the whole production line with the complete set of equipment is complete, and for the new dyeing factory of zhengzhou, shijiazhuang dyeing and northwest first dyeing factory provides complete sets of equipment, to open the precedent of printing and dyeing industry in China, then complete foreign aid exported to Asia, Africa and other countries.

　　At that time, the pre-treatment equipment was a long process, from the steaming, rolling, hydrogen peroxide bleaching of the fabric, rope and width washing of the fabric, and then to the washing of the nine-grid flat washing tank, rolling mill, steam box, drying, the process was very long. At that time, the rolling car was pressurized by heavy hammer, and the front and rear transmission of multiple flat washers was driven by long side shaft. The flat washers and steam boxes were castings, and only the heated cement plywood was made of steel plate. The pillars of the dryer were castings. The 570-mm diameter drying cylinder was made of copper. The 2.5-mm copper plate was welded and then rolled into a drying cylinder. According to the instructions of vice premier li xiannian at that time, we quickly replaced the drying cylinder and solved the problem. Later, the drying cylinder was changed to straight welding and the material was changed to stainless steel.

　　Dyeing part of the equipment is also a long process of hot melt dyeing machine, vulcanizing pad dyeing machine, hot air primer machine and color soaping machine. Batch dyeing is done with a coil dyeing machine.

　　Printing machine has four colors, six colors and eight colors drum printing machine, printing machine according to the number of colors divided into three models, 5-181 for four colors, 5-182 for six colors, 5-183 for eight colors. The locomotive is not universal, the second half is universal, forming a "big dog walk big hole, small dog walk small hole". Printing machine drying with drying cylinder is also copper, 1.5 meters in diameter, drying cylinder welding is manually into the large drying cylinder, outside with a small fan to send air, oxygen, to prevent the operation of workers hypoxia suffocation. Later there was a round screen, flat screen printing machine, drying room into hot air. Some of the old four, six, eight color drum printing machine into the museum.

　　After finishing equipment at that time only three roll, six roll calender, then long, short process of resin finishing, liquid ammonia finishing and other new technologies. Later, a variety of fabrics such as fuzz, milling, ginning and other finishing equipment have emerged at the right moment, a complete variety, greatly improve the quality of fabrics and fabrics.

　　When the complete set of printing and dyeing machinery and equipment started production, the policy of specialized production and cooperation had not been considered. The general parts and special parts of printing and dyeing machinery are produced by the main machine factory at the same time along with the main machine, such as edge absorber, cloth guide roller and so on.

　　Later, the production of printing and dyeing machinery was gradually adjusted, and the huangshi textile machinery factory and shaoyang no.2 textile machinery factory were built to undertake part of the production tasks of printing and dyeing machinery. The production capacity has been expanded and the variety has been gradually increased. In such a situation, the conventional finishing production line after printing and dyeing is finally formed, that is, step by step according to rolling, washing, steaming, drying units and special parts, special parts, to implement professional production and collaboration. After reasonable division of labor, Shanghai, jiangsu and the mainland three lines at the same time division of production, forming geographical support.

　　Circular screen and flat screen printing machine in printing equipment are researched and developed on the basis of introducing technology and digesting and absorbing, realizing industrialization and gradually replacing roller printing machine. The parts of printing and dyeing machinery, such as nickel mesh, cloth guide roller, drying cylinder, edge absorber, etc., have also formed a professional and intensive production, rotary screen printing machine USES a variety of specifications of nickel mesh annual output of several million, cloth guide roller annual output of tens of thousands of, reflects the efficiency, quality stability, cost reduction characteristics.

　　The development of printing and dyeing industry is relatively difficult, because it involves fabrics, dyes, auxiliaries, printing and dyeing technology, public works water quality, steam pressure and power stability and other special requirements, and equipment as a carrier, just a part of it; In addition, the printing and dyeing industry is close to the market, close to consumers, demand changes quickly, but also to achieve a low carbon economy, save water and reduce pollution requirements. Textile machinery production to adapt to the development of printing and dyeing industry and scientific and technological progress, but also need to make great efforts in the future.
