Abstract:

In order to develop micro-nanofibers fibrous with efficient air filtration performance, the micro-nanofiber fibrous nonwovens were formed by one step method of high speed hot gas flow drafting based on melt blown technology with polyethylene glycol/polypropylene (PEG/PP) as the materials. The relationships between fiber arrangement, fineness distribution, porosity and filtration efficiency, filtration resistance and mass factor were analyzed experimentally. Results show that the fibers with diameter less than 800 nm are interspersed among fibers with diameter more than 4 000 nm, showing the embedded feature of the macro superposition in the direction of thickness and the micro quasi continuous branch in the horizontal direction. With the increasing of the PEG mass ratio from 0% to 8%, the fiber embedding rate of the fibers with diameter less than 800 nm increases from 0.00% to 784.66%. At the same time, the filtration efficiency increases by about 1.12 times and the mass factor shows a gradual increasing trend. It is shown that the embedded structure of the micro nanofiber material is beneficial to the capture of fine particles in the continuous fluid, which is helpful to improve capturing the fine particles in continuous fluids.
