Abstract

The invention discloses a yarn method and device for implementing color mixing of double-color roving through asynchronous / synchronous two-stage drafting. A drafting and twisting system comprises a primary drafting unit and a secondary drafting unit arranged at the front and back and a double-ingredient combining twisting unit; the primary drafting unit comprises a combined rear roller and an intermediate roller; the combined rear roller comprises a first rear roller and a second rear roller abreast arranged on the same rear roller shaft; the linear velocity ratio Vq / Vz of a front roller to the intermediate roller is constant, and the yarn blending ratio is dynamically regulated online so as to regulate the yarn color through regulating the rotating speed of the first rear roller and / or second rear roller. The color mixing proportion control for the colored spun yarn produced by the method is more uniform and precise, and the color change is richer.

Description

technical field [0001] The invention belongs to the field of ring spinning in the textile industry, and in particular relates to a yarn method and device for realizing color-mixing by different-synchronous secondary drafting of two-color rovings. Background technique [0002] There are two traditional color spinning processes, one is to make slivers of different colors by pre-spinning mixed colors, and then the spun yarn is drawn and twisted to form melange yarns; the other is to draw two different colored rovings by drafting The middle and rear rollers of the mechanism are fed separately, and one of the rovings is unevenly drafted, and then merged and twisted to form bamboo segment colored yarn. [0003] Color spinning is to selectively mix colored fibers (dyed fibers or liquid dyed fibers), and then spin them into colored yarns with a certain color. Use this colored yarn for yarn-dyed weaving, and form color distribution on the fabric by mixing colors, such as grid fabric...
