Abstract

The invention discloses a micro-nano fiber yarn spinning device and a spinning process thereof. The micro-nano fiber yarn spinning device comprises a spinning jet, a yarn feeding system, a fiber polymerization mechanism and a twisting mechanism, wherein the spinning jet is composed of a hot air pipe, a polymer melt pipe and a cold air pipe, the yarn feeding system is composed of cheese yarns, an unwinding roller and a yarn guide rod, the fiber polymerization mechanism is composed of an upper roller and a lower roller which are mutually connected in a meshed mode, a plurality of micro-pores are formed in the bottom of the groove of the lower roller, and an irregular air pipe is further arranged inside the lower roller. The micro-nano fiber yarn spinning device is reasonable in structure and process design, convenient to operate actually and capable of spinning micro-nano fiber sprayed out of the melting-spraying spinning jet into micro-nano fiber core spun yarns, the micro-nano fiber wraps the surfaces of core yarns, and the attachment rate and the working efficiency are high, so that produced yarns have the functions of microbial resistance, heat insulation, heat preservation, filtering and adsorption, sound absorption 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 and a spinning process thereof. Background technique [0002] Melt blown spinning technology is mainly used in the production of nonwovens. Flame-blown nonwoven technology originated in the early 1950s, when the U.S. Naval Laboratory, with government funding, researched and developed filter materials for collecting radioactive particles in the upper atmosphere after nuclear bomb explosions. Extruded into a concentrated hot air flow through the extruder, the ultra-fine fibers formed under the stretching effect of the air flow are blown to the condenser, thereby accumulating into an ultra-fine 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 technology into civilian use, and jointly established a...
