Preparation method of geotextile with high tensile strength
The invention relates to a preparation method of geotextile with high tensile strength, which comprises a first geotextile layer, a second geotextile layer, a protective layer, a tear-resistant layer and a reinforcing rib layer, the upper end of the protective layer is connected with the lower end of the first geotextile layer, the upper end of the tear-resistant layer is connected with the lower end of the protective layer, and the upper end of the reinforcing rib layer is connected with the lower end of the tear-resistant layer. The first geotechnical cloth layer is connected with the upper end of the reinforcing rib layer, the second geotechnical cloth layer is connected with the lower end of the reinforcing rib layer, the tear-resistant layer is made of latticed glass fiber filaments, the thickness of the tear-resistant layer is 0.4 mm-0. 7mm, the reinforcing rib layer is made of polyester drawn wires, the thickness of the reinforcing rib layer is 0.2 mm-0. 5mm, the protective layer is made of polypropylene fabric, and the thickness of the protective layer is 0.6 mm-0. The process is simple, the tensile strength, toughness and mechanical strength of the geotextile can be effectively improved by utilizing the latticed glass fiber anti-tear layer, the geotextile is effectively prevented from being easily torn or damaged under the action of external force, the effect is remarkable, the service life of the geotextile is prolonged, the cost is saved, and the application prospect is wide. The market application field of the geotextile is further expanded.
本发明涉及一种具有高抗拉强度的土工布制备方法，包括第一土工布层、第二土工布层、保护层、抗撕裂层和加强筋层，保护层的上端连接第一土工布层的下端，抗撕裂层的上端连接保护层的下端，加强筋层的上端连接抗撕裂层的下端，第二土工布层连接加强筋层的下端，抗撕裂层的材质为网格状玻璃纤维丝，厚度为0.4mm‑0.7mm，加强筋层材质为涤纶拉丝，厚度为0.2mm‑0.5mm，保护层材质为聚丙烯织物，厚度为0.6mm‑0.9mm。本发明工艺简单，利用网格状玻璃纤维丝抗撕裂层可以有效的提高土工布抗拉强度，提高土工布的韧性和机械强度，有效的避免土工布在外力作用下轻易发生撕裂或者破损，效果显著，延长了土工布的使用周期，节约了成本，进一步扩大了土工布的市场应用领域。
