Melt-blown nonwoven fabric production system capable of increasing particle embedding rate

Abstract

The invention discloses a melt-blown nonwoven fabric production system capable of increasing a particle embedding rate. The system comprises a feeding hopper, a system motor, a screw extruder, a die head, a reception roller, a hot air source, and a feeding device. The feeding device includes a stirring motor, a connecting flange, a rigid coupler, a sealing ring I, a stirring rod, a powder wheel, a powder falling cavity, a hot air channel, an air vibrator, channel steel, a storage chamber, a flexible coupler, a motor support, a drive motor, a T stand, a sealing ring II, a nozzle, an airflow inlet, and an airflow outlet. The characteristics and beneficial effects of the melt-blown nonwoven fabric production system are that activated carbon nanoparticles can be guided to melt-blow airflows, high-temperature and high-pressure airflows mixed with the activated carbon nanoparticles draw melt-blown fibers, the nanoparticles mixed in the hot airflows act on the melt-blown fibers at a certain speed and are adhered to the surfaces of the melt-blown fibers, and thus the binding strength between the activated carbon nanoparticles and melt-blown fabrics can be improved.

Description

technical field [0001] The invention relates to nonwoven fabric production technology, in particular to a melt blown nonwoven fabric production system capable of increasing particle embedding rate. Background technique [0002] For a long time, people have been wanting to produce nanoparticle composite melt-blown materials, that is, to keep a certain amount of nanoparticles in the melt-blown fiber web, and at the same time try to avoid particles falling from the melt-blown fiber web, that is, dusting. At the same time, nanoparticles must be introduced into the surface of the melt-blown fiber to improve the surface properties of the melt-blown fiber web. At the same time, they must be more uniformly dispersed on the surface of the fiber. Once they are coated, their efficacy is difficult to exert. The current methods of adding nanoparticles to meltblown fibers mainly include the following: [0003] The first is polymer melt blending, that is, adding functional nanoparticles w...

Problems solved by technology

However, there are still some outstanding problems, such as the low embedding rate of functional nanoparticles, poor firmness, etc.

[0007] Within the scope of the applicant's search, there are currently few domestic studies on the production system of melt-blown nonwovens that can increase the particle embedding rate, and there are no literatures on the production system of melt-blown nonwovens that can increase the particle embedding rate. see the report
