Production device and process of rotor-spun filament as well as short-fiber core-spun yarn and covered yarn

Abstract

The invention relates to a production device and process of a rotor-spun filament as well as a short-fiber core-spun yarn and a covered yarn, and belongs to the technical field of spinning. The production device comprises a filament frame, a filament drum, yarn guide rods, yarn guides, filament guides, a yarn forming device, yarn introducing rollers and a spindle, wherein the filament drum is arranged on the filament frame; a plurality of yarn guide rods are arranged below the filament frame; the yarn guides are arranged on the yarn guide rods; the filament frame and the yarn guide rods are fixed above a vehicle body; the filament guides are arranged below the yarn guides; the filament guides are connected with the yarn forming device; the yarn introducing rollers and the spindle are arranged in turn above the yarn forming device. The production device has the advantages of high composite yarn forming efficiency, adjustable tension over a relatively wide range and the like, can producethe core-spun yarn with relatively large tension and the covered yarn with relatively small tension, and can produce the covered yarns with different filament coating effects by controlling the tension of the filaments.

Description

technical field [0001] The invention relates to a rotor spinning filament and short fiber core-spun yarn and covering yarn production device and its technology, belonging to the technical field of spinning. Background technique [0002] The yarn forming process of rotor spinning reduces the roving process and winding process compared with ring spinning, and at the same time, the yarn drawing speed is 5-10 times higher. The selection range of raw material length, fineness, stiffness and other indicators is wider. The yarn forming in the closed yarn forming device reduces the phenomenon of flying flowers, and has the advantages of short process, high efficiency and high cleanliness of the production environment. [0003] The composite yarn system of rotor spinning combines the excellent wearability of staple fibers and the functionality of filaments, and is one of the key development directions of rotor spinning. The existing rotor spinning composite yarn system adopts the fo...

AI Technical Summary

Problems solved by technology

During the position of the filament from B to K, it affects the merging and stripping of the short fiber in the circle of the condensation groove where the point B is located, resulting in the phenomenon of broken ends in the continuous yarn formation of the short fiber bundle.

And the adjustable range of filament tension is very small, once it is slightly larger, it will interrupt the process of twisting and twisting of short fiber bundles and cause yarn breakage

Filament tension is an effective means to regulate the variety of composite yarns, but the inability to effectively control the tension has seriously affected the development of composite yarn varieties.
