Abstract

Disclosed are a tension adjustment method of a warp knitting variable-speed and uniform-tension yarn feeding device, and a weaving method. The device includes warp beams, connecting rod frames, a guide bar, a looping mechanism and a drawing and rolling-up mechanism, where the connecting rod frames are connected to yarn winding wheels and yarn guide plates, yarns are wound on the warp beams, and the yarn winding wheels are positioned between the warp beams and the guide bar; each of the yarn winding wheels includes a yarn inlet, a yarn winding shaft and a yarn outlet. According to the present disclosure, the tension produced in a yarn feeding process is actively adjusted by the variable-speed tension yarn winding wheels to make up tension error caused by looping; and the present disclosure is capable of compensating in time, does not easily break the yarns, is high in knitting efficiency and quality.
