Climate change causes diverse disasters, such as landslides and debris flow, and civil engineering thus becomes a common strategy for prevention and remedy. Geotextiles are textiles that are made of polymer materials, and have a variety of functions. One common function of geotextiles is reinforcement that uses their mechanical properties to defend the externally exerted force or secure soils. Geotextiles have a large range of applications and for example are used as reinforcement in dikes, hillsides, and foundations. Additionally, geotextiles can be formed into different structures to meet the requirements of the environment. In this study, the recycled Kevlar selvages are combined with polyester (PET) and polypropylene (PP) fibers in order to form nonwoven geotextiles. The otpimal amount of Kevlar fibers is examined. PET cont. filaments are then laminated on the geotextiles that are made with optimal Kevlar amount, and then needle punched. The properties of the product are evaluated. The test results suggest that the addition of either Kevlar fibers or PET cont. filaments results in improvement in the mechanical properties of the geotextiles.
