Abstract

The invention discloses a colorful bunchy yarn spinning method based on two-component combined type asynchronous and synchronous two-stage drafting. The method particularly comprises a drafting and twisting system which comprises a primary drafting unit, a secondary drafting unit and a combining twisting unit, and wherein the primary drafting unit, the secondary drafting unit and the combining twisting 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 two-component mixing ratio and dynamic changes of linear density are controlled through a primary asynchronous drafting mechanism, and datum linear density is controlled through a secondary synchronous drafting mechanism. The changes of the linear density (the shape of a bamboo joint attached to datum yarn) can be precisely controlled, and the change of the color of the yarn (the color of the bamboo joint and the color of the datum yarn of the bamboo joint) can be precisely controlled. Meanwhile, the middle roller is controlled to rotate with constant set speed, the reproducibility of the pattern type and color of the variable-linear-density yarn is guaranteed, and the spinning effect is more stable.

Description

technical field [0001] The present invention relates to the field of spinning in textile engineering, in particular to a method and device for regulating spinning thickness and blending ratio based on two-component heterosynchronous two-stage drafting, and a colorful slub yarn spun therefrom. Background technique [0002] Yarn is an elongated fiber assembly formed by twisting fibers in parallel orientation. The concept of linear density is generally used to express the thickness of yarn, and the thickness of yarn is its linear density. When the fibers are unevenly distributed in the length direction of the yarn, its appearance thickness (or linear density) will change, which is generally called slub yarn, also known as fancy yarn with varying thickness. If the blending ratio can be changed while the thickness is changed, fancy yarns with changes in thickness and color can be formed. We define this type of yarn as colorful slub yarn with changes in thickness and blending rat...
