何为“经遍”复合土工布 What is "Jingbian" composite geotextile

经遍复合土工布是以玻璃纤维（或合成纤维）为增强材料，通过与短纤针刺无纺布复合而成的新型土工材料。

The warp composite geotextile is a new type of geotextile made by using glass fiber (or synthetic fiber) as a reinforcing material and composite with short fiber needle punched non-woven fabric.

经遍复合土工布不同于一般机织布。其最大特点 是经线与维线的交叉点不弯曲，各自处于平直状态。用捆绑线将两者捆扎牢固，可全面较均匀同步，承受外力，分布应力，且当施加的外力撕裂材料的瞬间时，纱线会沿初裂口拥集，增加抗撕裂强度。

The woven composite geotextile is different from ordinary woven fabrics. Its biggest characteristic is that the intersection point of the meridian and the dimensional line is not curved, and each is in a straight state. Binding the two firmly with binding wires can comprehensively and evenly synchronize, withstand external forces, distribute stress, and when the applied external force tears the material, the yarn will gather along the initial crack, increasing tear resistance.

经遍复合时，即利用经遍捆绑线在经、维纱与短纤针刺土工布的纤维层间反复穿行，使三者编结为一体。因而经遍复合土工布即具有抗拉强度，低延伸率的特点，又具有针刺非纺织布的性能。因此经遍复合土工布是一种可用于增筋增强，隔离防护，并且有三维整体法向及水平较好的聚水、异水的作用。因其固体基质和气孔均呈连续相、成为多孔隙的过滤效应，是一种多功能的土工复合材料。它是当今国际上高水平的应用土工复合的基材。

During the process of warp lamination, the warp binding thread is used to repeatedly thread between the fiber layers of warp, vinylon, and short fiber needle punched geotextile, making the three interwoven into one. Therefore, the composite geotextile has the characteristics of tensile strength and low elongation, as well as the properties of needle punched nonwoven fabrics. Therefore, the composite geotextile is a type of material that can be used for reinforcement, isolation and protection, and has a three-dimensional overall normal and horizontal effect of water accumulation and differentiation. Due to the continuous phase of its solid matrix and pores, forming a porous filtration effect, it is a multifunctional geotechnical composite material. It is a high-level applied geotextile substrate in the international community today.
