01 Building materials

Building materials include a wide range of materials, mainly referring to roof waterproofing materials when it comes to the use of spunbonded nonwoven fabrics. Secondly, there are materials for wall insulation and sound insulation, wall base waterproofing, pipeline protection, underground drainage, and preventing tree root growth from damaging buildings. At present, in China, the application is mainly concentrated in the field of roof waterproofing materials.

In European and American countries, especially in Europe, this high-performance waterproof material has been widely used since the late 1980s and early 1990s, with a market share of over 40%, and most of it is PET spunbond based. The application of polyester felt base in China started relatively late, with a consumption of only 20 million square meters by 2000. But since entering the new century, new waterproof materials have developed rapidly. By 2002, the application of modified asphalt waterproofing membrane based on PET fiber reached 70 million square meters and continued to grow. It is predicted that in the next five years, modified asphalt waterproofing membrane will continue to develop at a fast pace, and its proportion in the total amount will increase to over 20% by 2010. The potential market for new waterproof materials in China is very large (approximately 8-1 billion square meters). With the continuous deepening of China's economic construction, PET spunbonded asphalt felt base has optimistic development prospects.

02 Geomaterials

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. In the early 1990s, its annual usage was over 300 million square meters, and in recent years, its usage has reached 700 million square meters. Geotextiles in Europe and Japan have also developed rapidly, with an annual consumption of around 400 million square meters in recent years. Among them, spunbonded nonwoven fabrics account for about 60% of the total; Japan saw significant growth in the application of geotextiles after the mid-1990s. Among Japanese nonwoven geotextiles, the use of spunbond method is the largest, accounting for about 60% of the total amount of nonwoven geotextiles, and mainly PET spunbond fabric.

The geotextile in our country started in the early 1980s, but the amount used at that time was very small and only an experimental application. It was not until the 1998 catastrophic flood that the government paid attention to the application of geotextiles and the construction department included them in the design specifications and formulated relevant national standards that geotextiles truly gained attention and development. At present, the usage of geotextiles in our country has exceeded 300 million square meters, and the proportion of nonwoven geotextiles in the total amount has reached about 40%. China's civil engineering construction has a huge potential market, which is no less than the current usage of 700 to 800 million square meters in the United States. Experts estimate that China's geotextile industry will continue to experience double-digit growth in the next 15 years, with PET spunbonded filament geotextile experiencing the fastest growth rate.

During the period from the 10th Five Year Plan to the 11th Five Year Plan, China planned to invest heavily in various projects such as water conservancy, electricity, transportation, environmental protection, and river management, including water conservancy construction, the South to North Water Diversion Project, electricity investment, highway and railway construction, environmental engineering construction, as well as projects such as ports, airports, garbage treatment, river and lake management, and sand control, with an investment of over trillion yuan. In the next 10 years or more, China will have more infrastructure projects to build, and the demand for geotextiles will also increase. China will become the world's largest marketing market for geosynthetics.

At present, these production lines mainly produce products such as geotextiles, engineering anti-seepage materials, building waterproof materials, composite reinforcement materials, automotive fabrics, cushioning materials, shoe chemical sheets, etc. Its prospects are very promising.

03 Home textiles and composite materials

According to the aging and high-temperature resistance characteristics of spunbonded nonwoven fabrics, they are widely used in home textiles, composite materials, luggage materials, etc. By high-temperature transfer printing, high-end and affordable fabrics are produced; And due to its resistance to aging; Deeply recognized by consumers.
