The application of geotextiles abroad has already begun in the 1960s, the United States is the world's largest geotextile consumption of the country, it in the early 90s on its annual consumption of more than 300 million m2 in recent years, the amount of 700 million m2 The Europe and Japan, geotextiles have also been rapid development, the European geotextile in recent years, the annual consumption is also about 400 million m2, of which spunbond nonwovens accounted for about 60% of non-woven geotextile; Japan in the mid-90s After the application of geotextile has a significant growth. Japan's non-woven geotextile to spunbond the largest amount, accounting for about 60% of the total non-woven geotextile, and mainly PET spunbond cloth.

China's geotextile cloth started in the early 80s, but at that time the amount of very little, but the experimental application. Until the 1998 floods caused the attention of the government, the construction sector to the geotextile application included in the design specifications to go, and developed the relevant national standards, geotextiles really get attention and development. At present, the amount of geotextile in China has more than 300 million m2, the proportion of non-woven geotextiles accounted for about 40% of the total. China's civil engineering construction has a huge potential market, its potential is no less than the current US consumption of 7 to 800 million m2. Experts estimate that China's geotextile in the next 15 years will continue to double-digit growth, which is growing faster PET spunbond filament geotextile.
During the 10th Five-Year Plan and the Eleventh Five-Year Plan period, China's investment in water conservancy, electricity, transportation, environmental protection, river management and other projects is huge, including water conservancy construction, South-to-North Water Transfer Project, power investment, highway and railway Construction, environmental engineering construction, as well as ports, airports, waste disposal, rivers and lakes management, sand control and so on projects, investment amounted to one trillion yuan. China in the next 10 years or more, there will be more infrastructure projects to build, the demand for geotextiles will be more and more, China will become the world's largest geosynthetics marketing market.
