以长度为51、65和150 mm的涤纶短纤维为原料，采用非织造针刺技术加工制得土工布。研究了原料纤维长度、针刺密度和针刺深度对土工布力学性能、厚度、垂直渗透系数的影响。结果表明：增加土工布原料纤维长度可以明显提高土工布力学性能；合理地选择针刺深度和针刺密度，有助于提高土工布的力学性能及透水性能。
以長度為51、65和150 mm的滌綸短纖維為原料，採用非織造針刺技術加工製得土工佈。研究瞭原料纖維長度、針刺密度和針刺深度對土工佈力學性能、厚度、垂直滲透繫數的影響。結果錶明：增加土工佈原料纖維長度可以明顯提高土工佈力學性能；閤理地選擇針刺深度和針刺密度，有助于提高土工佈的力學性能及透水性能。

The needle-punched nonwoven geotextile was made using PET fibers of 51, 65 and 150 mm.The influence of process parameters such as length of the fiber , punching density and depth of needle penetration on mechanical properties , thickness and vertical permeability coefficient of geotextile was discussed .The results show that the mechanical properties of the nonwoven geotextile increased significantly with the increase of the PET fiber length .The reasonable choice of the process parameters could enhance the mechanical and hydraulic conductivity properties of the nonwoven geotextile .
