Wu Yongsheng: Textile Machinery Production Needs Great Efforts To Adapt To The Development Of Printing And Dyeing Industry And The Progress Of Science And Technology.

Development of printing and dyeing industry

Compared with cotton textile machinery, the foundation of printing and dyeing machinery is relatively weak. Only a few private enterprises in Shanghai produced some printing and dyeing machinery at the beginning of the founding of the people's Republic of China.

However, there was a favorable condition for development at that time, that is, some printing and dyeing equipment in some printing and dyeing enterprises in coastal areas such as Shanghai, Jiangsu and Zhejiang, and they are still in operation and can be used for reference.

With such a foundation, I am familiar with Li Chuanlu, Ni Wenlin, Zhu Dihua and Xu Tiehua.

It is also ingenious that cotton textile materials were mainly cotton and cotton production was largely dependent on the weather.

Cotton production seems to have a regular pattern, with a bumper harvest in two years and a reduction in output in a single year.

During the harvest, the production tasks of textile machinery enterprises are full, and the textile machinery enterprises lose their jobs, stop work and train when they fail.

In 1955, cotton textile machinery reduced production and textile machinery enterprises had surplus production capacity.

Textile machinery design company including Shanghai office, a large number of technical personnel mapping design.

At that time, the pre-treatment equipment was a long process, from the fabric cooking, dipping, hydrogen peroxide bleaching, fabric rope and wash, and then to nine grid washing tank washing, rolling, steaming box, drying, the process is very long.

At that time, the rolling car was pressed by heavy hammer according to the pressure. The front and rear parts of the multiple washing flats were driven by long side shaft pmission, and the flat washing tank and the steamer were all castings, except that the heated water plywood splint was made of steel plates.

The dyeing part is also a long process hot melt dyeing machine, sulfurizing pad dyeing machine, hot air bottoming machine and color soaping machine.

Batch dyeing uses a tangle dyeing machine.

The printing machine has four color, six color and eight color roller printing machines. The printing machine is divided into three types according to the chromatic number, 5-181 is four colors, 5-182 is six colors, and 5-183 is eight colors.

The headstock is not universal, and the latter half is universal, forming "big dog walking big hole, puppy walking small hole".

The drying cylinder for printing machine is also made of copper. The diameter is 1.5 meters. The welding of the drying cylinder is manually entered into the big drying cylinder, and the outside is used to send air and oxygen to the interior with a small fan, so as to prevent operators from suffocating with oxygen.

Later, there was a rotary screen and flat screen printing machine, and the drying room was changed to hot air.

Some old four, six, eight color roller printing machines have entered the museum.

The finishing equipment had only three rollers and six roll calendering machines at that time. Later, there were new technologies such as resin finishing and liquid ammonia finishing for long and short processes.

Later, a variety of fabric finishing, grinding, knit and other finishing equipment came into being. The variety is complete, greatly improving the quality of fabrics and fabrics.

When printing and dyeing machinery and equipment were just started production, the principle of specialized production and cooperation was not taken into account.

The general parts and special parts of printing and dyeing machines are produced simultaneously by the main engine factory, such as sucking machine and cloth roller.

Later, the production of printing and dyeing machinery was gradually adjusted. The Huangshi textile machinery factory and the Shaoyang second textile machinery factory have undertaken some printing and dyeing machinery production tasks.

Production capacity has expanded and varieties have gradually increased.

Under such circumstances, the conventional printing and dyeing finishing production line is finally formed, that is, specialized production and cooperation should be carried out gradually according to rolling, washing, steaming, drying units, special parts and special parts.

After a reasonable division of labor, the three lines of Shanghai, Jiangsu and the mainland will work together to form regional matching.

The circular screen and flat screen printing machine in the printing equipment have been researched and developed on the basis of introducing technology and digestion and absorption, realizing industrialization and gradually replacing the roller printing machine.

The parts of printing and dyeing machinery, such as nickel mesh, cloth guiding roller, drying cylinder and sucking edge device, have also been professionally and intensively produced. The nickel screen produced by rotary screen printing machine has several millions of products per year, and the guide roller has tens of thousands of products per year, which embodies the characteristics of efficiency improvement, stable quality and low cost.

The development of printing and dyeing industry is relatively difficult, because it involves special requirements such as fabric, dyestuff, auxiliaries, dyeing and printing technology, water quality of public works, steam pressure and power stability, and equipment as a carrier is only part of it. In addition, the printing and dyeing industry is close to the market, closely related to consumers, and needs rapid changes, and it also needs to achieve low carbon economy, water conservation and sewage reduction requirements.

In order to adapt to the development of printing and dyeing industry and the progress of science and technology, textile machinery production still needs to make great efforts in the future.
