Effects of Needle-Punch Depth on Properties of PET/LPET/Kevlar Nonwoven Geotextiles

Abstract:

Geotextile has been commonly used in civil and geotechnical engineering applications, and the majority of geotextiles is made of nonwoven fabrics. Therefore, this study combines crimped polyester (PET) fibers, recycled Kevlar unidirectional selvage fibers, and low-melting-point PET (LPET) fibers to form PET/Kevlar/LPET nonwoven geotextiles, and then examines how various neelde-punch depths influence mechanical properties of the resulting nonwoven geotextiles. The tensile strength, tearing strength, bursting strength, and static puncture resistance of the nonwoven fabrics increase as a result of an increase of 0.3 cm to 0.5 cm in needle-punch depth. However, an increase of 0.5 cm to 0.7 cm causes a slight decrease in all aforementioned properties.
