Manufacturing process of high-count compact slubby yarns

Abstract

The invention provides a manufacturing process of high-count compact slubby yarns, which is characterized by comprising a spinning process. The spinning process includes: selecting raw materials including 60 counts of yarns and 30 counts of yarns according to the manner of combination of clearance piece control of low-count yarns and early drawing of high-count yarns, wherein the 60 counts of yarns include 50%wt of special long stapled cotton and 50%wt of fine stapled cotton, and the 30 counts of yarns include 85%wt of special long stapled cotton and 15%wt of fine stapled cotton. The manufacturing process of the high-count compact slubby yarns overcomes the defects of low strength and long and much hairiness of existing high-count slubby yarns and improves wearability of the high-count compact slubby yarns by technical innovation. Slubby yarns are combined by a compacting and bundling device so that the fabric surface has flat and clear appearance.

Description

technical field [0001] The invention relates to the technical field of textile fiber manufacturing, in particular to a manufacturing process of high-count compact spinning slub yarn. Background technique [0002] The existing slub yarn production method uses a single roving to be fed into the drafting area, through the slub yarn device, the rotation speed of the middle and rear rollers is changed, thereby changing the feeding amount of the roving, and the slub yarn with varying thickness is output through the front roller , under the action of the ring traveler, the output sliver is twisted around its own axial direction, but due to the change of the thickness of the yarn body, the transmission of the twist is concentrated in the detail part, and the twist at the thick place is relatively weak, especially When producing products with long slubs or large multiples, the yarn strength is low, the strength unevenness is large, and the hairiness is long, which makes the producti...

Problems solved by technology

[0002]The existing slub yarn production method uses a single roving to be fed into the drafting zone, and through the slub yarn device, the rotation speed of the middle and rear rollers is changed, thereby changing the roving The feeding amount of the slub yarn with varying thickness is output through the front roller. Concentrate on the details, and the twist at the thick joints is relatively weak, especially when producing products with long slubs or large multiples, it shows low yarn strength, large strength unevenness, and long hairiness, making it almost impossible to manufacture.
