“…As it is known, many parameters affect the electrospinning process, which are well described in the literature [11][12][13][14]16] . It is worth remembering that the polymer molecular weight is one of the most important parameters [11−14, 16, 22] .…”

“…It is worth remembering that the polymer molecular weight is one of the most important parameters [11−14, 16, 22] . In particular: (1) the greater the molecular weight, the lower the polymer concentration that assures the occurrence of sufficient chain entanglements and, therefore, the avoidance of bead formation [22] ; (2) the fiber size increases [13,14,16,22] with increasing molecular weight and polymer concentration in the electrospun solution.…”

Light Electrospun Polyvinylpyrrolidone Blanket for Low Frequencies Sound Absorption

Light polymeric soundproofing materials (density = 63 kg/m 3 ) of interest for the transportation industry were fabricated through electrospinning. Blankets of electrospun polyvinylpyrrolidone (average fiber diameter = (1.6 ± 0.5) or (2.8 ± 0.5) µm) were obtained by stacking disks of electrospun mats. The sound absorption coefficients were measured using the impedance tube instrument based on ASTM E1050 and ISO 10534-2. For a given set of disks (from a minimum of 6) the sound absorption coefficient changed with the frequency (in the range 200-1600 Hz) following a bell shape curve with a maximum (where the coefficient is greater than 0.9) that shifts to lower frequencies at higher piled disks number and greater fiber diameter. This work showed that electrospinning produced sound absorbers with reduced thickness (2-3 cm) and excellent sound-absorption properties in the low and medium frequency range.

“…The reasons for the use of fiber material are an economic factor and excellent sound absorption performance. Examples of fiber-based absorbers including natural material groups such as cotton (Gossypium arboretum L.) [5,6], sugarcane (Saccharum officinarum L.) [7], wood [8], tea-leaf-fiber (Camellia sinensis L.) [9], rice straw (Oryza sativa L.) [10,11], kapok (Ceiba pentandra L.) [4]; synthetic material group such as glass woll [12], polyacrylonitrile [13] and polyester [14]. Synthetic fibers have negative impacts including production processes which require large amounts of energy, causing high global warming potential [15,16] and air pollution which irritates on eyes and skin, also cause pulmonary disease [17].…”

The purpose of this research is to investigate the effect of bulk density, thickness, and air gap to sound absorption performance on absorber based sugar palm trunk fibers. The fibers were obtained from solid waste on Small-Medium Enterprises of sago flour processing in Klaten, Central Java, Indonesia. The absorber specimens were formed from the fibers using a simple press molding in an oven at 150 °C. According to ISO 10534-2, the absorber samples were tested using two microphones impedance tube with random noise source to get the curve of the sound absorption coefficient. The result shows that the absorption performance can be improved by increasing bulk density and increasing of sample thickness. Especially at low frequencies, improvement of the sound absorption coefficient can be achieved (NAC > 0.8) by applying the air gap behind the sample. The best performance of absorber based sugar palm trunk fiber can be achieved for (1 000 to 6 000) Hz range frequency.

“…Polyacrylonitrile‐based nanofibrous membranes were selected since they were affected less from ambient relative humidity and temperature changes. Moreover, PAN has been shown to be quite promising as a sound absorber . Results of the mentioned studies lead to the conclusion that the sound absorption performance of commercial felts could be enhanced when the felts are combined with a nanofibrous membrane.…”

“…Moreover, PAN has been shown to be quite promising as a sound absorber. 10,11 Results of the mentioned studies lead to the conclusion that the sound absorption performance of commercial felts could be enhanced when the felts are combined with a nanofibrous membrane. As a result of that, the study discussed in this paper focused on improving the sound absorption properties of commercial wool and jute felts by coating them with PAN nanofibers and using them as a lightweight sound absorber material in white goods.…”

Acoustic felts are commonly used in white goods. Bearing that into mind, this paper aims to enhance sound absorption behavior of such felts, in particular, within the low and medium frequency ranges. In doing so, wool and jute felt samples were coated with electrospun polyacrylonitrile nanofibrous membrane. These nanocoated felts were studied in terms of their sound absorption performance, air permeability, and surface morphology. The results indicated that the air permeability of the felts could be drastically decreased by coating with nanofibers, which was required for better acoustic performance of felt‐like structures. Moreover, the samples having higher amount polyacrylonitrile nanofibers tended to demonstrate better sound absorbency.
