Mechanical and Physical Property Evaluations of Kevlar/Polyester Complex Nonwoven Fabrics

Article Preview

Abstract:

Geotextiles made of nonwoven fabrics can be used in different fields, such as groynes, dams, seawalls, revetments, dunes, and hillsides, and the structures of nonwoven fabrics can be changed accordingly. This study explores the influence of different content of Kevlar fibers on the mechanical and physical properties of Kevlar/Polyester (PET) complex nonwoven fabrics. As specified in a nonwoven fabric manufacturing process Kevlar fibers and PET fibers are blended with various ratios to form Kevlar/PET complex nonwoven fabrics, which are then tested for tear strength, air permeability, and water permeability. The experiment results show that increasing Kevlar fibers reduces the tear strength, air permeability, and water permeability.
