The yarn is subjected to dry-to-wet and then wet-to-dry in the sizing process, and the influence of the change of the elongation of the yarn caused by the change of the dry and wet is overcome in the process. Particularly, the change in elongation due to the change in dry and wet of the yarn before and after sizing, and thus the change in yarn tension, affects the sizing of the yarn and the sizing speed of the yarn. The yarn is kept at a stable small tension in the sizing process, the sizing is affected by the large tension, the sizing quality is reduced, and the yarn is broken accidentally; if the tension is small, the yarns can move left and right because of no binding force, so that the yarns are twisted randomly, the twisted yarns cannot be split after being dried, and the yarns cannot be normally used.
