How Does Geotextile Fabric Come From? Its Historical Development Reveals!

Geotextile iswater - permeable geosynthetics made from synthetic fibers that are needled or woven. Geotextile fabric is one of the new materials geosynthetic material. 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 nonwoven geotextiles.

1. high strength, due to the use of plastic fiber, in the dry and wet state can maintain full strength and elongation.
2. Corrosion resistance, in different PH and soil can be long -  term corrosion resistance.
3. It has good water permeability. There are gaps between the fibers, so it has a good water seepage performance.
4. Good anti - microbial properties are not harmful to microorganisms and insects.
5. Its construction is convenient, because the material is light and soft. Therefore it is convenient for transportation, laying and construction.
6. Complete specifications: width up to 9 meters.

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 geotextile fabrics in Europe and Japan have also developed rapidly. The annual amount of geotextile fabric non woven used in Europe in recent years is also around 400 million tons, of which spunbond nonwoven 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 geotextile non woven fabric, and mainly PET spunbond.

Geotextiles in China started in the early 1980s, but at that time, the amount was very small. However, it was only experimental application. Until the 1998 floods caused the government's attention, the construction department put the application of non woven geotextile 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 nonwoven 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.
