Weaving capability of the commingled yarns applied to thermoplastic composites

The weaving capability of commingled yarns (GF/PP), which include micro-braided yarn,friction spun yarn, winding spun yarn and glass fiber yarn was carried out. Under the designed experimental conditions, after 100 cycles friction test, there was only a few hair appeared on the surface of the micro-braided yarn,and it's strength was hardly changed; but the friction spun yarn's wrapped fiber was peeled off completely, and its strength decreased 60%.As the test reached to 70 cycles,the winding spun yarn was broken; the glass fiber yarn brought lots of broken thread,and its strength decreased 52%.3D weaving test shows that micro-braided yarn has excellent weaving capability while the other yarns are difficult to be used for weaving, especially for weaving high densiny fabric and 3D fabric.
