Market and Application of Polyester Spunbonded Nonwovens

building material

Building materials include a wide range of materials. The materials involved in the use of spunbonded nonwovens mainly refer to roof waterproof materials, followed by materials for wall insulation and sound insulation, wall base waterproof, pipe protection, underground drainage, and prevention of tree root growth against buildings. At present, in China, the application is mainly concentrated in the field of roof waterproof materials.

In Europe and the United States, especially in Europe, this kind of waterproof material with superior performance has been widely used since the late 1980s and early 1990s. Its market share has reached more than 40%, and most of it is PET spunbonded base. The application of polyester linoleum tire base in China started late, and the consumption was only 20 million m2 by 2000. But since entering the new century, new waterproof materials have developed rapidly. By 2002, the application amount of modified asphalt waterproof coiled material based on PET fiber reached 70 million m2, and continued to grow. It is predicted that in the next 5 years, the modified asphalt waterproofing membrane will still develop at a rapid speed, and the proportion of the total will increase to more than 20% by 2010. The potential market of new waterproof materials in China is very large (about 8-1 billion m2). With the continuous development of China's economic construction, PET spunbonded linoleum base has an optimistic development prospect.


The application of geotextile in foreign countries began as early as the 1960s. The United States is the country with the largest consumption of geotextile in the world. Its annual consumption of geotextile was more than 300 million m2 in the early 1990s and 700 million m2 in recent years. Geotextiles in Europe and Japan have also developed rapidly. In recent years, the annual consumption of geotextiles in Europe has also been about 400 million m2, of which spunbonded nonwovens account for about 60% of nonwoven geotextiles; The application of geotextiles in Japan has increased significantly since the mid-1990s. Spunbonded geotextile is the most widely used nonwoven geotextile in Japan, accounting for about 60% of the total nonwoven geotextile, and mainly PET spunbonded geotextile.

The geotextile in China started in the early 1980s, but the amount of geotextile used was very small at that time, and it was only an experimental application. It was not until the catastrophic flood in 1998 attracted the attention of the government, the construction department included the application of geotextile in the design specifications, and formulated the relevant national standards that geotextile was really valued and developed. At present, the amount of geotextile used in China has exceeded 300 million m2, and the proportion of nonwoven geotextile in the total amount has reached about 40%. China's civil engineering construction has a huge potential market, which is by no means less than the current consumption of 700 million to 800 million m2 in the United States. Experts estimate that China's geotextile will continue to grow at a double-digit rate in the next 15 years, of which PET spunbonded filament geotextile will grow faster.

During the "Tenth Five Year Plan" and the "Eleventh Five Year Plan" period, China planned to invest heavily in water conservancy, power, transportation, environmental protection, river governance and other projects, including water conservancy construction, South to North Water Transfer Project, power investment, highway and railway construction, environmental engineering construction, as well as ports, airports, garbage disposal, river, lake and sea governance, sand control and other projects, with an investment of over a trillion yuan. In the next 10 years or more, China will have more infrastructure projects to build and more demand for geotextiles. China will become the largest marketing market for geosynthetics in the world.

Domestic production capacity of PET spunbonded nonwovens

At present, China has about 9 PET spunbonded production lines, with a total production capacity of about 31000 t/a. Among them, Yizheng Nonwovens Factory, Hunan Nonwovens Factory, Henan Sanli Company, Shanghai Jiasmaiwei Company and Jiangxi Guoqiao Company are production lines introduced from Italy or West Germany, while Shaoxing Lida, Xinjiang Tianli, Xichuan Nonwovens Factory, Dalian Hengda, Zhejiang Yongguang Nonwovens Factory and others are domestic production lines, with a minimum width of 2.4 m and a maximum width of 6 m. The maximum production capacity of these production lines is 4500 t/a, and the minimum production capacity is 1000 t/a. The 4.5m width PET spunbonded geotextile and linoleum base cloth dual-use production line designed and manufactured by the Nonwovens Technology Development Center in the textile industry and operating in Xinjiang Tianli Company is a domestic equipment with large production capacity and the best product quality, with an annual production capacity of 3500 t/a.

At present, the main products of these production lines include geotextile, engineering anti-seepage materials, building waterproof materials, composite reinforcement materials, automotive fabrics, cushioning materials, chemical sheets for shoes, etc. Its prospects are considerable.

Home textiles and composites

According to the characteristics of aging resistance and high temperature resistance of spunbonded non-woven fabric, it is widely used in home textiles, composite materials, luggage materials, etc. Through high-temperature transfer printing, high-grade and affordable cloth is produced; And because of its aging resistance; It is widely recognized by consumers.
