Problems solved by technology

[0005] ① When two different raw materials (or different colors) of roving are used as the main and auxiliary yarn strands, the blending ratio (mixing color ratio) of the slub yarn cannot be randomly adjusted; the three-component method has not yet been used to produce variable slub yarns, dot yarns, etc. Linear Density Yarn Method
[0007] ③The problem of uneven blending and yarn color matching can not achieve the expected purpose

Abstract

The invention discloses a three-component asynchronous and synchronous two-stage drafting colorful bunchy yarn spinning method. The method particularly comprises a drafting and twisting system which comprises a primary drafting unit and a secondary drafting unit, wherein the primary drafting unit and the secondary drafting unit are arranged front and back. The primary drafting unit comprises a combined rear roller and a middle roller. The secondary drafting unit comprises a front roller and the middle roller. The speed Vq of the front roller and the speed Vz of the middle roller are kept constant, only the rotating speed of the combined rear roller is adjusted, and the yarn intensity of yarn and / or the blending ratio can be adjusted at the same time. Color mixing of circle yarn, bunchy yarn and big-belly yarn produced through the method and device is more even and accurate, the middle roller is controlled to rotate at the constant set speed, it is guaranteed that the blending effect is more stable, and the color shading of the yarn of different batches has no obvious changes.

Description

technical field [0001] The invention relates to the field of spinning in textile engineering, in particular to a method and device for spinning colorful slub yarns by three-component synchronous two-stage drafting. Background technique [0002] Yarn is an elongated fiber assembly formed by twisting fibers in parallel orientation. When the fibers are unevenly distributed along the length of the yarn, there is a variation in its linear density or appearance. According to the size of this uneven distribution, it can be classified into slub yarn, belly yarn, dot yarn, etc., and they can be collectively referred to as fancy yarns with varying linear densities. If the blending ratio can be changed while the linear density of the yarn is changed, fancy yarns with variable linear density and color can be formed. We define this type of yarn as colorful variable density yarn, which can be divided into It is colorful slub yarn, colorful belly yarn and colorful dotted yarn. [0003] ...
