Polypropylene nonwovens with natural polymers addition for filtration applications (in English)
Polimery 2013, No 7-8, 557
Polypropylene composite nonwovens with microcrystalline cellulose (2 wt. %) and microbiological chitosan (3 wt. %) addition were processed by the melt-blown technique. The nonwovens were studied for filtration parameters and bio-destruction degree and the effect of chitosan on antibacterial properties of the polypropylene nonwoven was analyzed. The addition of modifiers resulted in impairing filtration parameters of polypropylene nonwovens but increased their biodestruction rate. Initial microbiological tests on nonwoven with chitosan indicated its anti-microorganisms effect towards selected colonies of bacteria and fungi.
Key words: melt-blown technique, microbiological chitosan, composite nonwovens, filtration
