The paper presents a method of obtaining poly(lactide) (PLA) nonwoven fabrics with antifungal properties using potassium iodide as a nonwoven modifying agent. PLA nonwoven fabrics were obtained by the melt-blown technique and subsequently surface modified (PLA→PLA-SM-KI) by the dip-coating method. The analysis of these PLA-SM-KI (0.1%–2%) composites included Scanning Electron Microscopy (SEM), UV/VIS transmittance, FTIR spectrometry and air permeability. The nonwovens were subjected to microbial activity tests against Aspergillus niger fungal mold species, exhibiting substantial antifungal activity. The studies showed that PLA-KI hybrids containing 2% KI have appropriate mechanical properties, morphology and demanded antimicrobial properties to be further developed as a potential antimicrobial, biodegradable material.

“…There is a broad range of different polymers which may be used in the melt-blowing process such as polystyrene, polyesters, polyamides, polyethylene, polycarbonate, polyurethane, polyphenylene sulfide but the one used most commonly is polypropylene [31]. Nowadays most nonwovens are made of neat polymers but there are some works that describes melt-blowing process in the presence of polyethylene glycol, magnesium stearate or silver nanoparticles to strengthen the filtration properties of the nonwovens [32,33] or with microcrystalline cellulose and microbiological chitosan to make them biodegradable [34]. For improvement of their thermomechanical properties, the nonwovens were fabricated with an addition of organo-modified nanoclay [35] or with graphite [36] as well as with CNT to obtain the temperature-sensitive sensors [37].…”

Thermoplastic nonwovens containing 2.5 wt% of multi-walled carbon nanotubes were manufactured by half-industrial melt-blowing process from two copolyamides belonging to the group of hot melt adhesives having different melt-viscosities. The initial masterbatches have been analyzed by their rheological and thermal properties to adjust the appropriate conditions of melt-blowing process which allowed to manufacture the nonwovens without structural defects. It was found using a scanning electron microscope that in 10 wt% masterbatches fewer agglomerates of the multi-walled carbon nanotubes occurred in less viscous coPA2 and their average diameter measured by ImageJ was 60 µm. For more viscous coPA1 some oval agglomerates with even 270 µm diameters have been detected but during the extrusion they were destroyed. Microstructural observations of the nonwovens showed that fibers occur in the entangled state and their average diameter is around 45 µm for each type of the copolyamides. Analysis of the electrostatic properties of the nonwovens with low and high areal weight showed that electrical surface resistivity is slightly higher for the nonwovens based on coPA2 and those with higher areal weight. Using high-resolution microscope, it was possible to ascertain that in the nonwovens made of coPA1 + 2.5 wt% the carbon nanotubes are well-dispersed with their visible alignment along the fiber axis, unlike those in the nonwovens made of coPA2 + 2.5 wt% which occur mainly as lightly connected bundles without any specific orientation. The developed nonwovens can be used as interlayers to increase the electrical and mechanical properties of composite structures in the aerospace and automotive sectors.

Recently, a substantial body of research has shown interesting possibilities of using nonwoven structures in advanced applications in a variety of sectors, including the construction industry, medicine, transportation, textiles, the automotive industry, and so on [4][5][6]. Such nonwovens may differ in terms of quantitative and qualitative composition, morphological structure, physical and chemical properties of the incorporated modifiers, hydrophilicity and hydrophobicity, as well as structural modification technologies [7][8][9][10][11][12][13][14][15][16].Over the past years, increased sensitivity to micro-and nanometric particles has induced greater user expectations concerning enhanced filtering properties of nonwovens. Highquality PP melt-blown nonwovens are needed, for instance, in sectors using the so-called clean technologies [17,18].

In this work, a method for introducing zeolites and mesoporous siliceous materials into the melt-blown process for the production of polypropylene nonwovens was developed and the functional materials obtained were tested. Both types of additives were introduced in the melt-blown technology using a device placed in the duct of the die assembly. Nine types of polypropylene melt-blown nonwovens were made with different types of zeolites (clinoptilolite, Na-X, Na-A, Na-P1, sodalite, Na-P1 with hexadecyl trimethylammonium bromide (HDTMA), ZeoEco 20, and BioZeo R.01) or mesoporous silica material (Mobil Composition of Matter No. 41, abbreviated as MCM-41). The nonwovens were studied in terms of protective and functional parameters: sodium chloride and paraffin oil mist aerosol penetration, airflow resistance, and sorption capacity for toluene, ammonia, acetone, and cyclohexane, in accordance with the requirements of the European standards concerning respiratory protective equipment. The tests showed that zeolites and MCM-41 can be successfully incorporated within the structure of elementary polymer fibers using an environmentally friendly “dry” melt-blown technology with nonwovens modified so as to impart multiple functionalities in one integrated technological process. The developed method of introducing the studied materials to polypropylene melt-blown nonwovens led to the production of new multipurpose materials with good protective and functional properties. The best polypropylene nonwovens were produced with the addition of 250 g/m2 of MCM-41 or Na-P1 zeolite modified with HDTMA.
