Technology And Industrialization Of Low Melting Point Polyester Staple Fiber

He has been engaged in research, development and production management of oil and downstream chemical fiber products for a long time. He is the head of the project.

Responsible for determining the overall design plan of the project, controlling key nodes and difficult points in the overall process of the project, guiding the direction and providing solutions.

Decision making for technical pformation of existing production equipment.

Finally achieve low melting point polyester compound short.

Successful mass production, and create a profit of 100 million yuan / year.

Main innovation points of the project

1. develop independently low melting point of good spinnability.

It has produced low melting point polyester compounds with good spinnability and cohesiveness.

2. the coloring of the raw liquor was first applied to low melting point polyester, and the color masterbatch and coloured low melting point polyester fiber with low melting point polyester carrier were developed independently without dyeing.

The world's first developed a coloured and environment-friendly low melting point polyester staple fiber.

3. granulating equipment and spinning equipment innovation, strengthen the underwater device, solve the problem of paste and particle temperature in the process of granulation.

Using the screw extruder with vacuum device, the low melting point polyester wet cut pellet is directly fed into the extrusion melt, which solves the problem that the melting point is low and can not spin after hot air and high temperature drying of the normal polyester.

Since 2010, the quality of the product has been further improved, and the output has been successfully completed in 2013. The annual output reaches 25 thousand tons and the output value reaches 300 million yuan.

The gross profit of accumulated creation is nearly 100 million yuan and foreign exchange earning is 12 million US dollars. The processing and utilization of the products reach non-toxic environmental protection effect, and the grade of downstream products is greatly improved. All modified raw materials can be obtained domestically and easy to be industrialized.

Chou Zhenhua has been committed to the research of new technology and principle of jeans dyeing for many years. He is the technical director of the project. He is mainly responsible for the research and development of the technology of denim yarn, reactive dyestuff, wet short steaming, dyeing and finishing, cleaning and dyeing equipment, digital on-line detection and control integration technology, digital online collection system key technology research and development, modified liquid adding control technology, dyeing tank liquid balance balance water supply technology research and development, and the research and development of the antique style high-end colorful cowboy series products.

Main innovation points of the project

1. cowboy yarn coating and reactive dyestuff wet short steaming process technology, short process, realize salt free dyeing, compared with traditional cowboy yarn dyeing technology, 10000 meters through water saving 85%, energy saving more than 30%, basically realize zero discharge of waste water; denim yarn production process temperature and humidity control and salt free dyeing, enriching the variety of cowboy products.

2. independent research and development of clean dyeing equipment, digital online detection and control integration technology, digital online collection system key technology, to achieve precise temperature and humidity control technology in denim yarn production process, adding control technology of modified liquid, and water balance technology of dyeing tank.

3. development and preparation technology of unique modifiers, environment-friendly adhesives.

4. the dye is circularly distributed on the cross section of the yarn to meet the market's demand for the antique style colorful denim series products.

The project has built 1 clean and dyed yarn production lines for denim yarn. Through the implementation of this project, it can promote the synchronous development of the related textile printing and dyeing enterprises in China, and it has a positive and positive effect on the implementation of energy saving, environmental protection and cleaner production technology in the printing and dyeing industry.

In 2013, the sale of clean dyed denim fabrics was 7 million 200 thousand meters, with an additional profit of 11 million 730 thousand yuan and a tax of 5 million 570 thousand yuan.
