How does geotextile come from? What kind of history does it have?

Geotextiles, also known as geotextiles, are water-permeable geosynthetics made from synthetic fibers that are needled or woven. Geotextiles are one of the new materials geosynthetic materials. The finished products are cloth-like, generally having a width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextiles and non-woven geotextiles.

The application of geotextiles abroad began as early as the 1960s. The United States is the country with the largest geotextile consumption in the world. Its annual consumption in the early 1990s was more than 300 million? In recent years, the amount has reached 700 million? . Geotextiles in Europe and Japan have also developed rapidly. The annual amount of geotextiles used in Europe in recent years is also around 400 million tons, of which spunbonded nonwovens account for about 60% of non-woven geotextiles; Japan was in the mid-1990s. Later there has been a significant increase in the application of geotextiles. Japan's non-woven geotextiles use the largest amount of spunbond, accounting for about 60% of the total non-woven geotextile, and mainly PET spunbond.

Geotextiles in China started in the early 1980s, but at that time, the amount was very small, but it was only experimental application. Until the 1998 floods caused the government's attention, the construction department put the application of geotextiles into the design specification, and formulated the relevant national standards. The geotextile was really valued and developed. At present, the amount of geotextile used in China has exceeded 300 million m2, and the proportion of non-woven geotextiles has reached 40%. China's civil engineering construction has a huge potential market, and its potential is never lower than the amount of 7 to 800 million m2 used in the United States. Experts estimate that China's geotextile fabrics will continue to grow in double digits in the next 15 years, of which PET spinning spunbonded filament geotextiles will grow faster.

During the period of the '15th Five-Year Plan' and the 'Eleventh Five-Year Plan' period, China’s investment in various projects such as water conservancy, power, transportation, environmental protection, and river management is huge, including water conservancy construction, South-to-North Water Transfer Project, power investment, roads and railways. Construction and environmental engineering construction, as well as ports, airports, garbage disposal, rivers, lakes and seas, governance, sand control, and other projects, have reached trillions of dollars in investment. In the next 10 years or more, China will have more infrastructure projects to build and the demand for geotextiles will increase. China will become the largest market for geosynthetics in the world.
