Lipase production by Acinetobacter radioresistens was performed in a 2-L tank fermentor equipped with a nonwoven fabric, which was made of nylon 6 fiber and coated with a hydrophobic acrylic resin. The fermentation medium contained 2% (v/v) n-hexadecane as the carbon source. The use of the nonwoven fabric was intended for the dispersion of hydrocarbons; thus, the contact surface for the cells t...

In this paper, we present a new fuzzy selection criterion which takes into account both the sensitivity of measured data and human knowledge concerning the relations between process parameters and quality features of nonwoven product. This selection criterion permits to rank the process parameters of the related nonwoven production line and take the most relevant ones as input variables of the ...

The presence of jet-marks, or jet-streaks, on the surface of hydroentangled nonwoven fabrics, is usually regarded as an undesirable outcome of the hydroentangling process. Jet-streaks degrade aesthetic features and physical properties of the resulting fabrics. Jet-streaks are associated with low tear strength along the machine direction and nonuniform appearance. Reducing or eliminating the occ...

In this work, we present the development and characterisation of new cement-based composite panels reinforced with fibres recovered from wastes protective technical clothing. The developed a flexural strength (?15 MPa) fracture toughness (?3.5 kJ/m 2 ) that are suitable for their application on ventilated façades. environmental impact these was evaluated through life-cycle assessment (LCA) crad...

To accelerate healing of severe hemorrhagic wounds, a novel highly absorbent hemostatic dressing composed of a Tencel®/absorbent-cotton/polylactic acid nonwoven base and chitosan/nanosilver antibacterial agent was fabricated by using a nonwoven processing technique and a freeze-drying technique. This study is the first to investigate the wicking and water-absorbing properties of a nonwoven base...
