摘要

Polypropylene and polylactide meshes were produced by additive technologies. The optimal parameters for producing polymer meshes on a 3D-printer were determined. It was shown that the specified mesh structural parameters differed from those obtained, which had to be considered for their production. Polypropylene and polylactide meshes obtained on a 3D-printer were capable of triboelectrification during use involving deformation of the hybrid fibrous material. The amount of retained xerographic powder after rubbing the meshes against each other and the appearance on them of a constant electric field were shown to increase significantly by 1.4-2.2 times for polypropylene mesh and by 3.2-3.4 times for polylactide mesh. Manufacturing multi-component filter materials by coextrusion of polypropylene and polylactide to produce non-woven polymer fabrics and air filters based on them was proposed.
