In civil engineering where textiles are used extensively, prices are an important factor in determining the use of geotextiles. Polypropylene industrial yarn is one of the preferred raw materials for woven geotextiles when the fabric strength requirements are high. From the point of view of the process, the raw material for the production of polypropylene industrial yarn (polypropylene chips) is easily available, there is no special requirement for raw material slicing (compared with the production of common polypropylene yarn), the air-supply process does not require air conditioning, and the energy consumption is the lowest, so the polypropylene industrial yarn The production cost is much lower than that of the polyester industrial yarn and the nylon industrial yarn.

At present, the geotextile raw materials used in domestic projects are mainly nylon high-strength filaments, which have not been widely used due to high prices. With the development and application of polypropylene industrial yarn, due to its low cost and performance, it will surely replace it. Recently, their experimental results show that polypropylene industrial yarn can completely replace the nylon industrial silk weaving geotextile and geo-bag fabric, and the cost is reduced by one-third.
