Problems solved by technology

[0005] However, the electrospinning technology usually has complicated equipment and inconvenient operation, and the nanofibers adsorbed on the surface of the filament will still peel off.
Moreover, in the process of combining nanofibers and spinning in the prior art, the nanofibers are often adsorbed on the side close to the nozzle, and the side far away from the nozzle is often unable to cover the nanofibers.

Abstract

The invention discloses a micro-nano-fiber yarn spinning device high in spinning efficiency and a spinning process thereof. The spinning device comprises a spinning head, a yarn feeding system, a fiber collection mechanism, a roller twisting mechanism and a twisting mechanism, the spinning head is constituted by a hot air pipeline, a polymer melt pipeline and a cold air pipeline, the yarn feeding system is constituted by yarn and a roller, the fiber collection mechanism is constituted by a receiving curtain, compressing rollers and winding rollers, the roller twisting mechanism is constituted by two roller twisting rolling wheels, and the yarn penetrates through the space between the two roller twisting rolling wheels. The micro-nano-fiber yarn spinning device is reasonable in structure and process design, convenient in practical operation, capable of spinning micro-nano-fibers into the yarn and achieving 360-degree complete cover, in particular to the surface of the yarn and high in fitting rate and work efficiency, redundant nano-fibers can be re-utilized, and the produced yarn has the functions of antisepsis, thermal insulation, sound absorption, filtration, adsorption and the like.

Description

technical field [0001] The invention relates to a spinning device and a process thereof, in particular to a micro-nano fiber yarn spinning device with high spinning efficiency and a spinning process thereof. Background technique [0002] Filament is a filament in a chemical fiber with a continuous length of several kilometers or tens of thousands of meters. It can be divided into two types: monofilament and multifilament. Chemical fiber filaments are widely used in various clothing, decoration and other industrial sectors, among which special filaments such as Kevlar fiber (Kevlar fiber), carbon fiber, and glass fiber are already wonderful in industrial applications. [0003] Nanofibers are easy to adhere to the filaments due to their good adhesion properties and surface adsorption, but they are also easy to peel off. The two filaments that have absorbed the nanofibers at the same time are further twisted and paralleled at the same time, and the effective embracing and twis...
