The existing three-dimensional woven fabric is woven by adopting a creel for warp feeding, but as the requirements of application ends on the thickness of the fabric are continuously increased, the number of required loom beams is also continuously increased, and the occupied area of the whole warp feeding system is huge. Taking the preparation of a three-dimensional woven fabric with the thickness of 1 cm and the width of 20 cm as an example, the rear warp let-off system needs to provide 5000 loom beams, the occupied area is up to 5 meters, and the length is up to 8 meters. Under the scale, because a single beam is adopted for yarn feeding, the yarn feeding amount is only about 70-100 m each time, the beam replacement labor intensity is extremely high and the frequency is frequent after the yarns are used up.

Meanwhile, the tension of the warp yarns on the shuttleless loom is often not well controlled, because the tension of the warp yarns can be large and small due to the phenomenon that the winding mechanism cannot hold the fabric when the loom is in a full shaft to an empty shaft, and the instability of the tension of the warp yarns has great influence on the quality of the woven textile.
