| titleOfInvention | Olive anti-attenuation high-strength PP spunbonded non-woven fabric |
| abstract | The invention provides an olive anti-attenuation high-strength PP spunbonded non-woven fabric, which has the MD strength of 41.74-42.45(N/5 cm); CD intensity 18.25-19.44(N/5 cm); the preparation process of the PP spunbonded nonwoven comprises the following steps: the polypropylene high polymer is melt extruded by a large screw extruder, and is subjected to filtration, spinning, air flow traction and stretching, then filaments are laid into a net, the fiber net is subjected to hot rolling and bonding by an upper compression roller, a lower compression roller and a rolling mill to form a spun-bonded non-woven fabric, and finally the spun-bonded non-woven fabric is wound and cut to prepare the polypropylene high polymer. The oral exam made of the spun-bonded non-woven fabric has good strong attenuation capability and electrostatic adsorption capability, the thermal attenuation resistance of the medical mask can be obviously improved, the number of charges is accumulated, and the electrostatic adsorption time of the medical mask is prolonged. |
