Spinning device adopting moistening method and spinning technology adopting moistening method

The invention provides a spinning device adopting a moistening method and a spinning technology adopting the moistening method, and belongs to the field of textile industry. The spinning device and the spinning technology are used for improving strength and softness of spun yarns, and reducing spun yarn hairiness. The spinning device adopting the moistening method comprises upper drafting rollers, lower drafting rollers, guide wires, bead rings, spinning spindles and a fiber moistening device. The spinning technology adopting the moistening method comprises the steps that 1, a water tank is placed below the lower drafting rollers, and liquid dropping heads of a liquid dropping device are installed above the upper drafting rollers; 2, an operating button on an operating control panel enables size or water to drop from the liquid dropping heads; 3, fibers to be spun penetrate through gaps between the upper drafting rollers and the lower drafting rollers, and the size or the water adhering to the surfaces of the upper drafting rollers moistens the fibers passing through the portion below the upper drafting rollers along with rotating of the upper drafting rollers; 4, the moistened fibers are spun into yarns under rotating of the spinning spindles, and the yarns are wound around the spinning spindles after penetrating through the guide wires and the bead rings.
