Carbon fiber is a high performance fiber that has the inherent intrinsic properties of carbon materials, as well as the soft processability of textile fibers. The carbon fiber has the characteristics of high strength and rigidity, but has small elongation, non-wear-resistant surface, poor spinning manufacturability and high dependence degree on spinning process equipment, and the current carbon fiber loom principle is as follows: the warp yarn is unwound from a beam (warp beam, creel), passes through a tension compensation device, passes through a heddle eye, is controlled by a heddle to move, forms a shed through the up-and-down movement of the heddle, interweaves with the weft yarn at the weaving shed to form a fabric, and is finally guided to a take-up roller through a take-up device to form a cloth roll. The let-off mechanism in the carbon fiber weaving process is particularly important, the warp is directly fed into the weaving machine through a plurality of groups of roller sets after being unwound from a bobbin in the prior art, and the problems that the tension is unstable and the fluctuation is large in the weaving process are caused, and finally the cloth cover quality of the carbon fiber fabric cannot be guaranteed.

Therefore, the let-off system of the traditional loom is not suitable for producing yarns with good elastic modulus such as carbon fiber and the like, and the let-off length difference of warp yarns on the inner layer and the outer layer and the tension difference caused by the difference of the friction force between the inner layer and the outer layer due to the large diameter of a wrapping roller or a false warp beam are not considered in the let-off yarn guide device.
