The effects of inclined water jets on bicomponent hydroentangled fabrics were investigated. The PET/COPET and PA6/PET hydroentangled fabrics were made by using designed inclined water jet apparatus. Effects of basis weight, water ts inclination angle and water jet pressure were discussed. The comparison was made on the average tensile strength of fabrics made by perpendicular water jets (0° inclination angle) and inclined water jets of 20° with pressure levels of 3 bars and 7 bars. It was found that increases of water jet pressure, the fabrics tensile strength were increased. Furthermore, increases of water jets inclination angle, fabric tensile strength of 60 g/m2 fabrics decreased while for 100 g/m2 fabrics tensile strength increased.
