They have become a new growth pole of China's textile industry.In 2018, the total fiber processing of industrial textiles accounted for 28% of the entire textile industry, and geotechnical textiles accounted for 6.76 of industrial textiles.Since 2013, China's geotextile production has grown at an average annual rate of 9.28 per cent, reaching 1.0624 million tonnes in 2018;At present, there are about 500 geotechnical textile enterprises in China, mainly small and medium-sized enterprises that produce non-woven geotextiles.In the future, China's geotextiles will maintain a growth rate of about 7.5, and value enhancement will become an important driving force for the growth of China's geotextiles industry.
according to li lingshen,Geotextiles were used in China's water conservancy projects before the 1980 s. Plastic films, polyethylene films, woven bags, etc. were used as anti-seepage and anti-erosion materials. After the 1980 s, modern geosynthetic materials such as spunbond and needle-punched geotextiles, geotextile bags, drainage belts, geogrid, etc. were introduced into key projects.The catastrophic flood in 1998 accelerated the development of China's geotechnical textile industry, and the industry formulated and implemented a number of standards and technical specifications. After 2010, the pace of technological innovation in the industry has accelerated, the application has been fully rolled out, and domestic geotechnical materials have been widely used in a large number of national key projects.
In view of the market situation of geotechnical textiles, Li Lingshen pointed out,In the future, the focus of China's infrastructure construction will be concentrated in the central and western regions, where the geological environment is complex and the territory is vast, and the performance requirements for geotechnical materials are higher and the demand is greater.In addition, China is a major contracting country for foreign projects. It is estimated that the demand for geotechnical materials for foreign projects undertaken by Chinese companies exceeds US $1.5 billion. Regarding the standardization system of geosynthetics, he introduced that there are 39 national standards in the field of geoengineering, mainly concentrated in the textile field; nearly 50 industry standards, involving textiles, water conservancy, transportation, railways, urban construction and other fields, can basically meet domestic geosynthetics. The production, application, testing and evaluation of materials. Regarding the progress of science and technology, he gave a detailed introduction from the development of raw materials for geotechnical textiles, product quality improvement, technological innovation, and application expansion.
Finally, Li Lingshen concluded that the breakthrough and application of new materials and technologies will promote the expansion of the field of geotechnical textiles and form more revolutionary alternatives; continuous large-scale infrastructure construction is an important guarantee for the stable development of China's geotechnical textile industry; infrastructure investment along the "Belt and Road Initiative" route will become the growth point of China's geotechnical textiles; and the industry's standard system and application norms will be more perfect, the concentration of the industry will increase and the development of the industry will be healthy and sustainable.

National Institute of Waterway Engineering (BAW) Engineer Matthias MaisnerBringPerformance and Environmental Impact of Geosynthetics for FiltrationReport. He introduced,Geotextile filters in waterways are always in contact with soil, groundwater and surface water, and each fiber can affect the leaching performance.Improper use of geotextiles may lead to the formation of microplastics. In order to test and evaluate the release of hazardous substances into soil and water, a dynamic surface leaching test method (DSLT) was developed. Since leaching occurs in all surface areas in contact with the leach (water), the inner surface of the geotextile must be considered to evaluate the DSLT test results. The release of microplastics is an important factor affecting the environment, the European Union proposed that environmental protection is a long-term indicator of the performance of geosynthetics, ISO TC 221 WG3 for this purpose uses the wear test method, which can simulate the wear of geotextiles under wet conditions to determine the release of microplastics.
