Abstract

A method and a device includes a drafting and twisting system. The drafting and twisting system include a first stage drafting unit, a successive second stage drafting unit and an integrating and twisting unit. The first stage drafting unit includes a combination of back rollers and a middle roller. The second stage drafting unit includes a front roller and the middle roller. The blending proportion and linear densities of the five ingredients are dynamically adjusted by the first stage asynchronous drafting mechanism, and the reference linear density is adjusted by the second stage synchronous drafting mechanism. The invention can not only accurately control a linear density, but also accurately control a color change of the yarn.
