Geotextile Production Line stated that with the rapid development of our society, my country's infrastructure construction is increasingly closely related to my country's economic development, people's livelihood and ecological protection. High-speed railway projects, anti-seepage projects related to garbage or sewage treatment, mining and ecological bag slope protection projects are all constantly putting forward higher requirements and more demands on geotechnical construction materials. Generally, textiles that are used with foundations, soil, rock, soil or any other civil materials and are part of man-made works, structures and systems are geotextiles. High-performance geotextiles often have excellent mechanical properties, light resistance, temperature resistance, aging resistance and other characteristics, which can better play the role of reinforcement, protection, isolation, water conduction and seepage control in geotechnical engineering.

geotextile production line manufacturer said that geotextile can be divided into woven geotextile, nonwoven geotextile and composite geotextile according to different preparation methods. Woven geotextiles can be roughly divided into three types of products, produced by weaving, weaving and knitting processes. Nonwoven styling geotextiles refer to products made from oriented or randomly oriented fibers, filaments, strips, etc. Bonding by spunbonding, needle punching or hot melt. Nonwoven geotextile has high production efficiency, good extensibility, mechanical properties and horizontal filtration performance. Compared with the first two kinds of geotextile, composite geotextile has more advantages. It consists of two or more geotextile or geotextile-related products. It has good comprehensive performance and is a high-performance geotextile widely used in various projects. In addition, according to the product shape, geotextiles can be divided into plane, tubular, ribbon, grid, rope and other special-shaped geotextiles.

Geotextile Production Line Manufacturer stated that the selection of geotextile raw materials must match the actual needs of the project, considering both the performance requirements of the geotextile on site and the cost of the product. At present, the raw materials for the production of geotextiles are mainly synthetic fibers, and a small amount of natural fibers are also used. Although natural fiber has the advantages of renewable, easy degradation and low cost, it is limited in various engineering applications due to its own shortcomings. Compared with natural fibers, synthetic fibers have the advantages of high strength and corrosion resistance. At present, almost all geotextiles use synthetic fibers, including polyester (PET), polyethylene (PE), polypropylene (PP), polyamide (PA) and polyvinyl alcohol (PVA).

Among them, PP is currently widely used, while PET is not as good as PP in alkali corrosion resistance, and its usage in geotextile is second only to PP. In addition, polyvinyl chloride, ethylene copolymer modified asphalt resin, chlorinated polyethylene and other polymer materials with special functions are also used in a small amount. The production of high-performance geotextiles usually requires the addition of additives to improve the performance of geotextiles, such as antioxidants, light stabilizers, ultraviolet absorption stabilizers, long-term heat stabilizers, processing modifiers, flame retardants, lubricants, antibacterial agents, etc.
