Non-biodegradable polypropylene, which poses a serious threat to the environment, is most utilized material in air filtration systems. Moreover, under conditions of high temperature and humidity, electrostatic charge melt-blown nonwoven fabrics treated with traditional corona electrets will quickly dissipate. Here, biodegradable polylactic acid, calcium stearate, an innovative hydrocharging tec...

Melt spinning of polypropylene nonwoven nanofiber mats is demonstrated using Forcespinning The effects of rotational speed and melt flow rate of polymer on fiber diameter were studied. It was observed that melt flow rate of the polymer plays a major role in nanofiber formation and uniformity. Differential scanning calorimetry and X-Ray Diffraction analysis indicate that the crystallinity of nan...

Thermal insulation and acoustic absorption materials play a significant role in the characteristics of energy-saving comfortable modern buildings. However, these two types are generally developed independently. This study highlights potential lightweight polypropylene nonwoven fabrics for building applications investigates how fabric structure affects thermal acoustical properties. An industria...
