The emergence of non-woven geotextile geotextiles later than weaving, the production methods are mainly spunbond method and acupuncture two, including acupuncture in our country a larger proportion. The raw materials used to polyester, followed by polypropylene and vinylon, the unit weight of 100 to 800 grams / square meter. Non-woven geotextile with greater elongation, to adapt to greater deformation, can be made into the appropriate size of the pores, and in the horizontal and vertical directions have better penetration. Therefore, the development of non-woven geotextiles fast, and has become a major component of geotextiles. (Bentonite waterproof blanket)
