The arduous efforts finally succeeded in achieving functionality.

。

In 2016, "the key technology of polyacrylonitrile filament and conductive fiber industrialization" was passed.

The identification of scientific and technological achievements fills the gap in the manufacture of polyacrylonitrile filament and conductive filament in China.

It has been greatly improved.

The overall technological level and international influence of the industry.

Through expert appraisal, the overall technology is achieved.

。

At present, the functional polyacrylonitrile filament has entered the batch production stage with an annual output of 100 tons.

Go into the acrylic filament industry.

Looking back on his research and development process, Tao Wenxiang, chairman of the company, always laughs. It seems that past difficulties and frustrations can be laughed away and everything is so calm.

In fact, no one or one thing can be casually succeed.

In 1995, Tao Wenxiang began to pay attention to the sales and production of acrylic filament in China. At that time, only Japan's MITSUBISHI Li Yang was produced on a small scale, but the technology blocked China, and the polyacrylonitrile filament in the market was in a difficult situation, and the conductive fiber of Pan was completely blank.

Tao Wenxiang has a keen market sense of smell. He thinks that the development of Pan filament and its conductive fiber is imminent.

At that time, he began to set up market research, set up the first production line, purchase and install equipment, in order to further understand the production characteristics of the product, he even tracked the factory's waste disposal vehicle.

Do not remember how many days and nights are "boring" on the production line, from day to night, and from dawn to dawn, is often a workshop, and a day passed.

In the workshop, Tao Wenxiang looked at the replacement machine of the five generation, and smiled with emotion: "when I was young, I could stay up late."

In countless days, the people around us changed their minds. Tao Wenxiang said, "I can't remember how much money I put in, how much energy I spent, how many questions I put up with, and I felt very difficult several times."

In 2006, Tao Wenxiang completed the design and process exploration of filament equipment, and the first production line of acrylic filament was launched. Many years of R & D work has finally come to the surface. In 2008, the 12 spindle test spinning machine came out; in 2010, a stepped modular polyacrylonitrile filament device was developed to complete the modular test stage.

After that, in the cooperation with Donghua University, the project progressed more smoothly. In 2013, the ladder type modular acrylic filament production system was established. In 2015, the automatic production line was established. In 2016, the automatic production line of polyacrylonitrile filament was developed, and the industrial production was realized. It is the only enterprise in the world to produce polyacrylonitrile filament.

During this period, Tao Wenxiang changed five production lines and developed a single ingot single spray technology to solve the problem of broken wire, no capacity, inefficiency and poor quality of the product.

Now, the machines that have been eliminated are quietly placed in the corner of the workshop, and years have passed over them, grinding the brilliance of an industry.

Polyacrylonitrile filament has the characteristics of anti-aging, anti-corrosion and easy to functionalization. It is a key material for high-end military fabrics such as high-end simulation fabrics, strategic weapons and aerospace, and is a symbol of high-end preparation in the field of fiber.

Compared with other synthetic filament yarn production capacity is low, China's Acrylic filament is still in the early stage of development.

At the symposium, Dr. Chen Ye of Donghua University introduced the process of research and development.

He said that the localization of polyacrylonitrile filament is faced with bottlenecks of homogenization and high purity requirements. The process stability is high, and there are no existing spinning and polishing equipment.

In order to break through these bottlenecks, the project group, based on fully studying the characteristics of polyacrylonitrile filament forming, has constructed the homogenization preparation technology of polyacrylonitrile filament and its stable and continuous production technology system, and made high-quality polyacrylonitrile filament and its conductive fiber. It has realized four major innovative technologies, namely, the efficient and stable preparation technology of filament grade polyacrylonitrile, the continuous preparation engineering technology of high quality polyacrylonitrile filament, the high-efficiency polyacrylonitrile filament spinning and twisting technology and the key technologies for preparing copper polyacrylonitrile conductive fiber.

Chen Ye said that every breakthrough in innovation and technology needs to overcome numerous difficulties. For example, in the process of high quality polyacrylonitrile filament continuous preparation engineering technology research and development, in order to solve the problems of small denim breakage, filament yarn, instability of fiber strand drafting points, and many defects in fiber interior and surface, the project group invented the key technologies of polyacrylonitrile filament spinning spinning, steam bath drafting, heat pipe densification and high temperature plastic deformation.

It is reported that at present, Xiangying special fiber company has high quality and high stability polyacrylonitrile filament preparation, ultra fine polyacrylonitrile plus twisting filament preparation and copper ion complex acrylic fiber conductive fiber preparation technology. The only 100 ton polyacrylonitrile filament production line in China is established. The product has high strength and stable quality, and its fabric has good air permeability, antibacterial and wrinkle resistance. It is applied to the field of shielding equipment, special clothing and other fields of military equipment.

At present, Xiangying special fiber company has declared more than 15 patents, authorized 6 national invention patents, 7 utility model patents, 3 self owned trademarks, and 1 leading industry standards, with complete independent intellectual property rights.

It also won many honorary titles of Jiangsu high and new technology enterprises, Jiangsu private technology enterprises, state-level Torch Plans, Jiangsu high-tech products, excellent science and innovation team and Suzhou Engineering Center.

In addition, the product is also included in the 2017/ 2018 China fiber fashion trend.

In the new era, technology, fashion and green become the new orientation of the textile industry. Every technological progress will push the industry forward.

As a leader of a private enterprise, Tao Wenxiang has always fought in the forefront. The joint Donghua University has seized the core technology, promoted the further development of the industry, enhanced the competitiveness of science and technology in the industry, and made contributions to the construction of a textile power.
