Nonwoven Industry: A Leap From Big To Strong

Nonwovens are new recruits in the textile industry. They are textiles produced by chemical chips or staple fibers, such as polypropylene, polyester, nylon and so on. They do not need spinning, weaving, dyeing, and other complicated links. They can be directly woven directly.

Compared with traditional textile methods, nonwovens are a major change.

The production process of nonwovens is very short, and has the advantages of less people, less land occupation, less energy consumption, low cost, variety, wide use and high efficiency.

Compared with traditional textile methods, its efficiency can be as high as several times or even hundreds of times.

Promotion of non

Although we are the leading producer of Nonwovens in the world.

But compared with the developed countries (mainly the United States, Germany and Japan), we are not a powerful country.

In terms of nonwovens production, there are about 2000 nonwoven enterprises in China, but most of them are small enterprises, and there are less than 20 large factories with an annual output of tens of thousands of tons.

Most of these small enterprises focus on short-term benefits and are satisfied with the status quo. Their equipment technology, product quality and management level are generally not high, and they are quite different from those of advanced enterprises abroad.

In terms of nonwoven equipment, there are dozens of equipment in China.

In terms of technological innovation, although domestic enterprises will also have some small reform and innovation, most of them are copying foreign equipment and technology, and the quality of imitation is very different, lacking originality.

For more than 20 years, we basically ran behind others.

Take spunbonded equipment as an example, Germany has reached the 4 type ten years ago, and we are still very hard to reach the level of 2 type equipment. The gap is far too far.

We have hardly ever developed a new type of nonwovens production technology.

In terms of development mode, most enterprises are

In terms of product quality and variety, although the quality of non-woven fabrics produced by German imported equipment in some factories in recent years is of good quality and can reach international level, the quality of many products is obviously lower than that of the United States, Germany and Japan.

Our products are also very simple. For example, our more than 800 PP Spunbond production lines basically produce the same species and form fierce market competition.

Therefore, we import tens of thousands of tons of high-grade nonwovens from abroad to make up for our shortcomings and defects every year.

To sum up, China's nonwoven fabric is the largest producer in the world in terms of output, but there is still a certain gap in quality, variety, technology and modern management level of enterprises.

Change to high, vertical, deep and broad directions

Nonwoven fabric is a major revolution in the traditional textile industry. Although China's output has reached 2 million 795 thousand tons in 2010, it accounts for only 7.76% of the total output of 36 million tons of textile fiber products in the country, while the proportion is very small. For China's 1 billion 370 million population, the per capita possession is only 2kg, while the per capita possession of the national textile fiber products is 26kg, so the output of nonwoven fabrics is far from the peak, and there is still much room for development.

According to experts predict, the future textile industry in the world will form a "three cloth and vertical" situation, namely, the 3 production methods of shuttle weaving, knitted fabric and nonwovens are parallel; and experts predict that after 50 years, the textile will be mainly made of nonwoven fabrics.

The new textile technology of nonwovens has great vitality.

The output of Nonwovens in China in 2002 was only 632 thousand and 500 tons, but by 2010 it reached 2 million 795 thousand tons, an increase of 4.4 times.

In the future, if the annual growth rate is 8%, the output of China's nonwovens will reach 6 million 30 thousand tons by 2020, and 13 million tons by 2030.

This forecast is calculated at an average annual rate of increase of 8%, which is a very conservative measure. For the past 20 years, the actual annual growth rate of Nonwovens in China is over 8%, with an average increase of about 20%.

According to 8%, 20 years later, China's nonwovens output will exceed 1000 tons, that is to say, it will form a "three cloth stand" with shuttle weaving and knitted fabrics.

This is a very magnificent project, which is an epoch-making revolution for the national textile industry.

The pformation of nonwovens industry is imminent, and the extensive mode of development has no way out.

In the future, we must change from the big country to the production power. In the future, the production and construction of the nonwoven projects must be changed. In particular, we should change to the 4 aspects of high, longitudinal, deep and wide.

High: high and new technology, high production speed, high quality and high output.

In the future, when new engineering projects are being made, the advanced equipment should be selected as far as possible, and the existing equipment should be gradually reformed in this direction, so we must never repeat the production mode of low level, low speed and low yield.

Vertical: refers to the development of enterprises in the depth direction, and enlarges the pformation of old production lines, such as single head to multi head, single variety to multiple varieties, and production of functional, differentiated and diversified nonwovens.

Deep: the enterprise should march towards the depth of production, instead of simply staying on the production of white nonwovens. It should make deep processing of products and form diversified products to adapt to the market.

Conditional enterprises can also start from raw material production, so that the added value and economic benefits of enterprises can be greatly improved.

Guang: the so-called wide refers to the extensive opening up of new fields. The products of the factory are wide, customers are wide, the market is wide, the geographical area is wide, the use is wide, and the train of thought is wide.

We must let go of big strides, and we can not stop for a long time.

Research and development of Nonwovens for clothing

At present, all kinds of nonwovens produced in China are basically limited to the range of industrial textiles.

Although the market is quite large in this category, we still need to work hard to develop it.

In addition to industrial cloth, clothing will be more and more cloth, and nonwovens should be developed in this regard.

The technological innovation of nonwovens has many aspects, but its main direction should be to develop a new technology and technology that can be applied to garment fabrics.

At present, there is no such a mature technology in the world. If we want to become a world's nonwoven power, we must overcome this technical difficulty.

The requirement of this nonwovens is very strict. Generally, it must have very high uniformity of mesh, good vertical and horizontal strength, good drape performance, good handle, abrasion resistance, no fuzz, good air permeability, good moisture absorption, easy dyeing and printing, finer fiber, and stable dimension.

In recent years, the two-component superfine fiber spunbonded and Spunlaced technology developed in China has achieved initial success, but there are still problems in uniformity, non fuzzing and draping.

It is believed that within a few years, China's scientific research departments and enterprises will be able to overcome this technical difficulty.

Using nonwovens as clothing materials, the easiest way to start is to make casual clothes, camouflage clothes, which are not too high requirements, and their consumption is very large.

For example, in camouflage clothes, 6 million college students are enrolled in the country every year. When they enter school, each person has two weeks of military training. They must have one set of camouflage suits. Only 6 million of them will be required. A set of camouflage clothes should be used in 1kg calculation, and 60 thousand tons of cloth must be used, and the PLA and the armed police force are even larger.

In terms of casual wear, the amount of consumption in the country is even larger and difficult to calculate.

In a word, nonwovens can be made into garments. It will be a great revolution. This will be a revolution in the textile industry. It can greatly reduce the cost of clothing. It can save a lot of chemical fiber factories, spinning mills, weaving mills, printing and dyeing factories and other large factories, large quantities of equipment, large amounts of energy consumption, large module investment, a large number of pportation costs and a large number of textile workers' labor intensity. Its economic significance, political significance and social significance are very huge.

For thousands of years, traditional textile technology is a historic change.

It is impossible for our country to become a world nonwoven enterprise. It is impossible to rely on some small scale enterprises. We must build a large number of "aircraft carrier" large enterprises, such as the DuPont Co of the United States, Germany's Fort del fort and the company of Lai Feng house.

The state should plan and purposefully cultivate a batch of "aircraft carrier" enterprises, and help them with funds, talents and materials, so that the annual production capacity of these enterprises can reach 50 thousand ~10 tons or more, and they can develop world-class nonwovens equipment. In particular, these enterprises must have a high degree of enterprising spirit, be bold in innovation, attach importance to skilled personnel, and keep forging ahead.

If we can produce 10~20 DuPont nonwovens in the next 10~20 years, our dream of a powerful nation can be realized.
