Abstract:

In order to develop new varieties of yarns and improve the efficiency of yarn production, the method and principle of digital rotor spinning process were explored in this paper and the color characteristics of its products were studied. During digital rotor spinning process, three rovings were fed by three-component asynchronous feeding rollers, after combed, mixed and drafted by carding roller, mixed again in the rotor under the action of centrifugal force and condensing into sliver, and then twisted and wound forming a special yarn. By this novel process, the linear density and blending ratio can be controlled online with digital controlling system. It can be concluded that single fiber with different colors are well blended during spinning process, and digital yarns show softcolors.

Key words: digital rotor spun, yarn structure parameter, colorspun yarn, blended yarn
