Innovation Leads The Market For Nonwoven Equipment: Catching Up With The US, Japan And Europe.

After the introduction, imitation and digestion stage, the production of nonwoven machinery in China is developing towards the direction of independent innovation.

In recent years, some nonwovens equipment enterprises aim at the world's advanced manufacturing technology.

With the use of industrial textiles

In August 8, 2011, the China Hi-Tech Group Corporation bought the unit of the Limited by Share Ltd nonwovens mechanical carding unit.

The purchase target involves automatic control system, short fiber packer, nonwoven staple fiber netting and needle punching reinforcement production line and other complete sets of technical equipment and related patents.

The acquisition, China Heng Tian Group will form a complete chain of nonwoven equipment products. At the same time, the acquisition is also interpreted by the industry as the upgrading of China's Nonwoven machinery and equipment manufacturing level.

The gap with foreign countries is shrinking.

China's nonwovens industry started late, and the overall level and manufacturing capacity of the nonwoven equipment have been in a state of catching up with developed countries.

In recent years, the rapid development of China's nonwoven industry has provided powerful equipment and technical support for nonwoven products, and the technical gap between domestic nonwoven industry and foreign countries is gradually shortening.

At the fourteenth (Shanghai) International nonwoven exhibition held recently, the reporters saw some newly developed nonwovens production lines, which fully demonstrated the rapid upgrading of China's nonwoven equipment level.

An Haojie, deputy general manager of China Textile Technology Development Co., Ltd., a member of China's Heng Tian Group, told reporters about the development of the 5 die head (SSMMS) spinning and weaving composite nonwoven production line.

He said that the 5 die head production line is not simply overlapped with the original 4 module production line, but requires a lot of technological innovation and improvement.

The production line adopts the most advanced spunbonded and melt blown technology in the world today. The flexible and integrated design idea is adopted in the design, and its stability and versatility are greatly improved.

He said that in the spunbonded part, the four component feeding device, the precision module spinning box, the digital control and the opening structure of the draft duct and so on have improved the quality, speed and control ability of the paving. In the melt blowing system, the fast spinning assembly can meet the adjustment requirements of different kinds of products.

It is understood that the production line can reach 8000 tons / year, spinning speed up to 500 meters / minute, melt blown monofilament diameter up to 2 microns ~5 microns.

"At the same time, the production line also used our patented technology, quick change melt blown system components, so that production enterprises can flexibly combine spunbonded and melted spray production units to produce single melt blown or spunbonded products according to market demand, thus greatly improving the production efficiency and economic efficiency of enterprises."

Only innovation can lead.

At present, the production of nonwoven machinery in China is developing towards the direction of independent innovation after the introduction, imitation and digestion stage.

In recent years, some nonwovens equipment enterprises aim at the world's advanced manufacturing technology, boldly practice and boldly innovate, and have made a mark in the world's nonwovens equipment manufacturing field.

For example, Dalian Huayang Chemical Fiber Engineering Technology Co., Ltd. launched the world's first polyphenylene sulfide (PPS) filament spunbonded needle punched nonwovens production line.

The production line adopts the spunbonded + needle process, the product weight range is 100 grams / square meter to 600 grams / square meter, 2.6 meters wide, and the annual capacity is 1200 tons.

Ceng Shijun, general manager of the company, introduced the trial production of the production line at Foshan sloop special materials Co., Ltd. at the end of 2010. In June 2011, it passed the technical appraisal organized by the China Textile Industry Association and passed the product appraisal organized by the China Environmental Protection Association.

"Compared with the short fiber PPS needle products in the market, the equipment has the advantages of short flow, low labor force, low cost, and good product performance.

At present, there are no similar types of production lines and polyphenylene sulfide filament products in the world.

PPS spunbonded needle punched nonwovens have the characteristics of acid and alkali resistance, corrosion resistance and flame retardancy. They can work in the range of 170 to 190 degrees, and are the preferred coil materials in the fields of high temperature bag filter, chemical filtration, insulating materials, flame retardant materials and composite materials.

For a long time, PPS resin has produced the filter material by spunbond + needle. Now it belongs to the world's first.

The successful commissioning of the production line has greatly improved the leading level of China's PPS filter material production technology in the world.

An improved engineering production line of Dalian polyamide Spunlaced superfine fiber production line, a new engineering company in Dalian, which is known for its production of new nonwovens equipment, was successfully tested in Langfang Xinyuan nonwovens Co., Ltd.

On the basis of the original two-component (polypropylene / nylon 6) spunbonded spunlace process, the production line has changed a die head to two die heads. A new multi component combination spunbonded spunlaced process has been realized.

The production technology of two-component orange petal microfiber is only a few countries in the world. It has been widely paid attention by the industry because of its high technology content, short production process and wide application of products. The products have been applied in high-end medical, health, high-grade leather substrate, advanced cleaning cloth, clothing and apparel, and so on, which has great market prospects.

Based on the original two-component equipment, Dalian Hua Lun has developed a multi component technology route, providing excellent technical equipment for producing high-grade, super soft and tensile non-woven fabrics.

Catching up with the US, Japan and Europe

At present, though some progress has been made in the innovation of China's nonwoven equipment, the development of high-end products is still insufficient.

Mr. Guo Hexin, the honorary president of the China Spunbonded Nonwoven Industry Association, told reporters that since China could not produce some high-grade nonwovens products, China had to import more than ten million tons of high-grade nonwoven products from abroad to make up for the shortage of domestic demand every year.

He said that although China has more than 800 polypropylene spunbond production lines, but basically they are producing the same species, which has also created fierce competition in the domestic market.

He believes that although the development space of our nonwoven equipment is very large, the production and construction of nonwoven projects must be changed. Specifically speaking, it is necessary to pform into four aspects: high, vertical, deep and wide.

For example, the single head should be changed into multiple heads, single varieties should be changed to many varieties, and functional, differentiated and diversified nonwovens should be produced to change the situation of single varieties.

"At present, none of the world's top forty nonwovens enterprises are produced by single breeds and single stations."

Mr. Guo Hexin said.

Li Lingshen, President of China Industrial Textiles Association, said that with the gradual expansion of the proportion of China's industrial textiles in the total fiber processing in 12th Five-Year, the huge market potential of China's industrial textiles industry will soon be stimulated, which will bring a rare opportunity for the development of nonwoven equipment manufacturers.

However, it is unavoidable that China's nonwovens equipment is still quite different from the international advanced enterprises in terms of automation level, equipment accuracy, technological experiment conditions and quality reliability.

At the exhibition, the reporter saw a nonwoven BOQ online automatic detection analyzer exhibited by a foreign company. It can realize on-line automatic detection, adjust nonwoven weight, achieve automatic control and ensure product quality.

Although the product is small in size, its technical content is very high.

As such a device, our country can not independently produce at present, so the nonwovens equipment enterprises are not self belittling, but should work hard. Only in this way can we catch up with the developed countries such as the United States, Japan and Europe in a very short time.
