Manufacturing Process and Practical Examination for a 3D Structural Geocell Made from Recycled PET Fibers
In the recycle trend, this study used the low-melt polyethylene terephthalate fiber and the recycle wasted materials in producing nonwoven products. These two materials were combined together to form nonwoven products, which have good drain ability and high stress. Then, the high frequency plastic welding machine was used to manufacture the geocell of three dimension nonwoven cubic structure. This study discussed the bonding strength with different bonding length and width. The results show that the uniform of the bonding area resulted from the high frequency plastic welding machine affects the bonding strength. In low-power (tuner point to 2) bonding strength increases while the bonding time increases.
