Abstract

The invention relates to a production method of a roving pattern type colorful yarn. The production method comprises the following steps of A, manufacturing a colored cashmere wool net, that is, firstly, performing dyeing by adopting a cashmere loose fiber raw material, then performing mixing, and next, carding into the colored cashmere wool net through a cotton type carding machine; B, manufacturing a natural-color cashmere wool net, that is, performing mixing by adopting a cashmere loose fiber raw material, and then carding into the natural-color cashmere wool net through a 4-jointed wool type wool carding machine; C, enabling the colored cashmere wool net and the natural-color cashmere wool net to be overlaid to be synchronously fed into the wool carding machine to be cut into a plurality of wool rolls by belt wires; D, feeding the plurality of wool rolls into a self-acting spinning machine to reduce the draw for spinning, wherein in each wool roll, the wool roll of a half weight iswoven into S-twisted direction single yarn, and the wool roll of the other half weight is woven into Z-twisted direction single yarn; and E, performing combining and twisting on the S-twisted direction yarn and the Z-twisted direction yarn to form the roving pattern type colorful yarn, thereby greatly improving the evenness uniformity and improving fluffy feeling of the yarns.
