Discussion On The Application Fields Of German Industrial Textiles

Germany is one of the best economies in the euro area, and is less affected by the European debt crisis.

The famous commercial street in the eastern German city of Cologne is still a bustling scene of customers and tourists. It is similar to the scene of Beijing Wangfujing commercial street.

Chinese journalists who are in the bustling city are not at all aware of the existence of the European debt crisis. Instead, they add to the expectation of a turning point in the world economic outlook.

Germany is also a large industrial textile production and application country. In the fields of medical, health, automobile, urban rail, construction, wind power, engineering and other fields, many industrial textiles are used, such as the application of carbon fiber in building reinforced materials and glass.

Application in wind power generation equipment.

Recently, the reporter had the honor to interview on the spot, which deepened the understanding of Germany's application in the field of industrial textiles, and presented it to readers.

Application contest on Expressways

Industrial textiles can be seen at any time on the highways in Frankfurt, Germany, to Dresden, the former East German city.

In the far hills, dozens of wind turbines are made of huge glass blades made of glass fiber, rotating in the wind, forming a pastoral power map.

The European coastline is very long, and the wind power is large, and the potential of wind power generation is huge.

It is a good idea to use wind power to get clean energy. On the highway, the large trucks are PVC coated Pongab on both sides of the container, which will cover the freight pport strictly.

All freight cars in Germany must be shielded from both sides by Pongab. The bare cargo is fined.

Some of the trucks were painted with advertisements on Pongab, like moving galleries.

There are no billboards on either side of Germany's freeway, which makes up for this gap. At the gas station, there are often billboards, mostly woven with warp knitted fabric, which are good for the wind.

It is said that the speed limit of German freeway is largely based on the large number of geogrid materials used in the construction of the roadbed, which ensures that the road is flat, no collapse and no cracks. It provides a safety guarantee for drivers to drive at high speed.

The freeway is like a mirror, reflecting the speed of a country's economic development and its achievements in science and technology.

The application of industrial textiles in Germany Expressway shows the rapid development of German economy from one aspect.

There are not many places for China's highway application industrial textiles, even though there are many non-standard problems even though they are used.

For example, there is no national mandatory standard for truck cover cloth, freight trucks are running on their own, and the conditions of loading goods are not covered by regulations. This is very uncoordinated with the rapid development of China's economy.

From the perspective of the application of industrial textiles in Germany's freeway, is it enlightening to see the gains and losses in the application of industrial textiles in China's highways?

Preferred materials for future building reinforcement

Germany is the world leader in the use of carbon fiber and glass fiber as building reinforcement materials.

During his visit to Dresden University in East Germany, Sting, director of the center for industrial textiles research, introduced their research and development of reinforced materials for building textiles.

The carbon fiber grille woven with multi axial warp knitting machine is used in various building materials, such as sewer pipes, cement ceilings, road bridges and other cement components, and multi layer carbon fiber grid cloth is evenly laid. They are closely combined with cement and play a reinforcing role.

After such treatment, the building materials are lightweight, rusty, durable and so on.

Sting said that the carbon fiber mesh material used in bridge building structure has been reduced by 70% to 80%, and the strength has been greatly improved.

In an interview with Shanghai's "World Expo" in 2010, the reporter found that many German carbon fiber reinforced building materials were exhibited in Germany. This time, Germany witnessed its processing and production process, which impressed Germany's use of carbon fiber as building reinforcement material.

Due to the high cost of carbon fiber reinforced building materials, the penetration rate in China is very low.

In the construction of the 2008 Olympic Games venues, China Textile Research Institute of China Textile Science Research Institute used polypropylene as building reinforcement material, and explored a more economical method of building enhancement.

But carbon fiber as building reinforcement material should be the future direction of building textiles.

Carbon fiber has high strength, no corrosion, no rust, and light weight. For example, sewer pipes can ensure long-term safe use; making ceiling makes buildings light weight, small settlement, waterproof and impervious, and simple in construction.

These excellent performance indicators make carbon fiber the first choice for future building reinforcement materials.

Using 300K and below carbon fiber staple as building strengthening materials, the cost can be further reduced, and the enhancement effect is obvious.

Overcome the dilemma and take the lead.

The world's warp knitting leader, the German Carle Meyer group, has a history of 75 years.

His founder Mr. Karl Mayer and his family always believed in technological innovation and excellent product performance.

The current chairman, Fritz P Mayer (Fritz Mayer), told reporters that the success of Carle Mayer is the quality, performance and innovation of the product.

"Based on the global strategy at the beginning, we always focus on the future of our customers."

He said.

At the Carle Meyer group headquarters in Obertshausen, Germany, there are 200 engineering designers and developers who are engaged in research and development of new products for computers tomorrow.

In the east of Germany, Carle Meyer Marley, an industrial textile equipment factory, and vice president of marketing, AXS wtmeyer, visited the workshop of producing multi axial weft knitting machines.

Carle Mayer's high speed warp knitting machine technology has always been in the leading position in the world. The new RS Raschel warp knitting machine with parallel weft insertion device and the multi axial braiding machine with a speed of 2000 turn makes the visitors sigh for Karl Mayer's advanced technology.

In particular, multi axial weft insertion technology is a technical difficulty of warp knitting equipment. It is necessary to solve the problem of "dilemma" by Carle Meyer, not only for high speed weft insertion but also for high speed.

Just as "horses must run well and horses do not eat grass", there are much more intangible technological aspects than actually seen.

It is understood that the domestic production of high-speed warp knitting machine, reaching 1000 turns is already very difficult.

To achieve 2000 rotation and achieve uniform weft, the technical gap is not small.

Changde Textile Machinery Co., Ltd. is an early entry into the field of high-speed warp knitting machine production. At present, the speed of the high-speed warp knitting machine produced by them is about 1000 rpm, and the target 1500 becomes the goal of the company.

China

Zhu Xianmin, vice president of the equipment association, after watching the multi axial high-speed warp knitting machine manufactured by Carle Meyer, admitted that the overall technology of China's textile machinery manufacturing enterprises is still different from that of Carle Meyer, Germany, and there are still many things to learn from advanced foreign technology.

What is learning? Technological innovation is the first priority.

According to the introduction, Carle Meyer's annual R & D investment accounts for 20% of the company's sales. According to the sales amount of 16 million 80 thousand euros in 2011, the research and development input of up to about 3000000 euros makes the company's warp knitting machine technology always in the leading position in the world.

In the field of industry, multi axial high speed warp knitting machine can be used to produce carbon fiber and glass fiber grille for building engineering. Parallel weft knitting machine can be used to produce advertising cloth, tent cloth and printed coating base cloth. These fields are advanced in equipment and less employed, forming a market competition depression, and are favored by some enterprises.

It is understood that in 2011, Carle Meyer industrial textile equipment department exported 400 multi axial high-speed warp knitting machines to China, and only 300 warp knitting enterprises in Haining, Zhejiang.

Among them, 30 of the multiaxial equipment used in the production industry are purchased by Chinese enterprises, namely, enterprises in Beijing, Inner Mongolia, Shandong and other places.

Reporters noted that Carle Meyer's website has a saying: "we are concerned about your future."

The future market competition is the competition between technology and service.

To provide all customers with advanced technology and equipment and to maintain a fair and just partnership with their customers, Carle Mayer takes the lead in others.
