MORPHOLOGICALLY OPTIMIZED NONWOVEN TEXTILES BASED ON NANOFIBRES

摘要

The prepared space nanostructures contain drop-like spacing microspheres and/or are made of a combination of micro- and nanofibres and/or consist of nanofibres of polymers eventually polymeric mixtures that ensure formation of more voluminous space structures that may be prepared by a suitable combination of variables at the electrospinning process. The more voluminous space structures embody a larger thickness and area mass of the filtration material in comparison with planar structures, hence, the so much required enhancement of mechanical properties and of manipulability with the filtration nanomaterial. However, if we compare the planar and space nanostructures that have the same pressure drop, then the materials with space morphology have a larger effective surface of fibres and better filtration properties in elimination of ultrafine particles (filtration efficiency and, hence, also the quality factor).
