Miltas nanomanufacturing systems are specialized to produce nano structures. Our nano manufacturing technology is based on hybrid magnetic and electric field technology.

Hybrid systems use magnetic poles to oriente the nanofiber directions to produce uniform nano fibers, meanwhile electric field continously produces nanofibers. Miltas electromagnetic field spinning sytems can produce high quality nano fibers and nano particles.

Large surface area, brilliant surface adhesion, highly porous structure with uniform pore size, and light weight, to capture PM particles from the air. Nanofibrous membranes are among attractive air filters that exhibit fascinating features, including higher molecular orientation fibers and larger tensile strength.

Special properties, such as large specific surface area, high porosity, small pore size, and good interconnected pore structure provides the capture of fine particles and makes the electrospun polymer nanofibers applications in the filtration.

Nanofibers which continue to motivate the development of novel nanotechnology due to their extraordinary properties including small fiber diameters and the concomitant large specific surface areas, as well as the capabilities to control pore size among nanofibers and to incorporate antimicrobial agents at nanoscale.

Electromagneticspun nanofibers membranes for air filtration

Small fibers in the submicron range, in comparison with larger ones, are well known to provide better filter efficiency at the same pressure drop in the interception and inertial impaction regimes. From submicron and up, better filter efficiency can be achieved at the same pressure drop.

Nanofibers have fiber diameters that are 5-10 times smaller than the smallest meltblown fibers available. Nanofiber filter media has become available to the non-wovens and filtration industries for a broad range of filtration applications. Nanofibers provide dramatic increases in filtration efficiency at relatively small. 

Nonwoven fiber-based air filters suffer from the disadvantages of large pore size and low porosity due to their microsized diameters.
Compared with these fibers to nanofibers emerge as an advanced nanomaterial, which integrates the structural features of relatively small pore size, open stacking pores, and highly adjustable porosity.



The Bacterial Filtration Efficiency (BFE) test is performed on filtration materials and devices that are designed to provide protection against biological aerosols, such as face masks, surgical gowns, caps, and air filters. This test is used for FDA 510(k) submissions for surgical masks, is required by ASTM F2100 and EN 14683, and complies with ASTM F2101 and EN14683. 

The Viral Filtration Efficiency (VFE) test follows the same procedure as BFE, maintained at 1100-3300 plaque -forming units (PFU) with a mean particle size (MPS) of 3.0 ± 0.3 μm.

The combination of traditional textile technology and electrospinning technology provides a new preparation method for development of efficient, green, and durable textiles and has promising application prospects.Electromagnetic spinning technology has broadened the application field of nano-antibacterial/viral/fungal materials.
