After years of practice and hard work, Tianhai has been in a leading position in product technology for a long time, leading the development direction of the geosynthetics industry, and has been recognized by government departments, industry associations and all walks of life. It is a national high-tech enterprise, a well-known Chinese brand, Shandong Famous Brand, Shandong Province Famous Trademark, National Geotextile Top Three Enterprises.
Types of geotextiles
Polyester filament geotextiles: “Tianhai” polyester filament geotextiles are made by forming and consolidating polyester filaments, and the fibers are arranged in a three-dimensional structure. It has good tensile, tearing, bursting, and puncture-resistant physical properties and chemical properties such as biological resistance, acid and alkali resistance, and aging resistance. It also has a wide pore size range, tortuous pore distribution, and good permeability. and filtration performance. Polyester filament singeing geotextiles are developed for pavement, and have unique single-side and double-side singeing patents to prevent cracks and prolong the service life of asphalt pavement.
Polyester (polypropylene) staple fiber needle-punched geotextile: “Tianhai” polyester (polypropylene) staple fiber needle-punched geotextile is made of high-quality polyester and polypropylene staple fiber through carding, laying, acupuncture, and processing. Single-sided or double-sided hot rolling according to requirements. The product has good flexibility, acid and alkali resistance, corrosion resistance, aging resistance, high strength, stable size, good water permeability, filtration and isolation performance, and convenient construction.
Woven geotextile: “Tianhai” geotechnical filter / woven geotextile is made of polypropylene flat yarn, which is composed of at least two groups of parallel yarns (or flat yarn), and has the characteristics of light weight, high strength and low elongation. , good integrity, convenient construction, good reinforcement performance and low price.
After years of practice and efforts, Tianhai has long played a leading role in product science and technology, led the development direction of geosynthetics industry, and won recognition from government departments, industry associations and all sectors of society. Tianhai is a national high-tech enterprise, a well-known brand in China, a famous brand in Shandong Province, a famous brand in Shandong Province, and one of the top three Geotextile enterprises in China.
Characteristics of 3 kinds of Geotextile
Polyester filament Geotextile: “Tianhai” polyester filament Geotextile is made by polyester filament netting and consolidation, and its fibers are arranged into a three-dimensional structure. It has good physical properties such as tensile resistance, tear resistance, bursting resistance, puncture resistance, as well as chemical properties such as biological resistance, acid and alkali resistance, aging resistance, etc. It also has a wide pore size range, tortuous pore distribution, good permeability and filtration performance
Performance. Polyester filament singeing Geotextile is developed for pavement, and has unique single and double singeing patents to prevent cracks and extend the service life of asphalt pavement.
Polyester (polypropylene) short fiber needled Geotextile: “Tianhai” polyester (polypropylene) short fiber needled Geotextile is made from high-quality polyester and polypropylene short fibers by carding, netting, needling and processing. It can also be hot rolled on one or both sides as required. The product has good flexibility, acid and alkali resistance, corrosion resistance, aging resistance, high strength, stable size, good permeability, filtration, isolation performance, and easy construction.
Textile Geotextile: “Tianhai” geotextile filter screen/textile Geotextile is composed of at least two groups of parallel yarns (or flat wires) with polypropylene flat wires as raw materials, which is characterized by light weight, high strength, small elongation, good integrity, convenient construction, good reinforcement performance and low price.
Generally speaking, geotextiles are made of high-quality polymer materials, including polypropylene(PP), polyester(PET), polyethylene, or polyamides which are handled by woven skills, needle-punched skills, or some heating methods. Geotextiles are durable geosynthetic materials that can be widely applied in the separation, filtration, reinforcement, protection, retainage, and drainage of the soil.
Geotextiles are marvelous materials for civil constructing projects such as the anti-seepage engineering of bridges, harbors, reservoirs, canals, dams, and any other retainage project. The 4 types of geotextiles we produce are divided into Polyester(PET) Filament Nonwoven Geotextiles, Polyester(PET) Staple Fiber Needle Punched Nonwoven Geotextiles, Polypropylene(PP) Staple Fiber Needle Punched Nonwoven Geotextiles, and Polypropylene(PP) Woven Geotextiles.
