Abstract

The invention discloses a novel micro-nano fiber yarn spinning device and technology. The device comprises a spinning nozzle, a fiber polymerization mechanism, a drafting mechanism and a twisting mechanism. The fiber polymerization mechanism is composed of an irregularly-shaped exhaust pipe, a grid ring and a tension frame. The drafting mechanism is composed of a first roller, a second roller, a leather roller and a cotton collector, wherein the leather roller and the cotton collector are matched with the first roller and the second roller. The novel micro-nano fiber yarn spinning technology comprises the steps that micro-nano fibers are formed at first, then reach the receiving device irregularly-shaped exhaust pipe along with airflow, are drafted finally and enter the twisting area to be twisted to form a micro-nano fiber yarn. The structure and technology design is reasonable, actual operation is convenient, super fine micro-nanoscale fibers formed through melt-blown spinning can be spun into the yarn under high fitting rate and high production efficiency, the produced yarn has the advantages of excellent heat insulation, heat preservation, adsorption, filtration, sound absorption and the like, and production of the micro-nano fiber yarn with the features and functions of bacteria resistance and ultraviolet resistance is achieved through melt component design.

Description

technical field [0001] The invention relates to a spinning device and a process thereof, in particular to a novel micro-nano fiber yarn spinning device and a spinning process thereof. Background technique [0002] Melt-blown spinning technology is mainly used for the production of nonwovens. It was first successfully developed in the United States in the 1950s. At that time, the U.S. Naval Laboratory was funded by the government to research and develop radioactivity in the upper atmosphere after the nuclear bomb exploded. Particulate filter material, the process is to extrude the molten polymer into a convergent hot air flow through an extruder, and the ultrafine fibers formed under the stretching action of the air flow are blown to the condensing device to accumulate into a A superfine filter material. This process is the prototype of modern meltblown nonwoven technology. In the mid-1960s, the American Exxon company improved the method, and in the 1970s, it turned this te...
