Abstract:
The present invention provides a meltblown wetlaid method for producing non-woven fabrics from natural cellulose using pulp as raw material and N-methylmorpholine N-oxide (NMMO) as solvent for dissolving into dope. The dope is then extruded out of a spinneret to form filament bundle by meltblown method. Subsequently, by means of ejecting mist aerosol of water, the filament bundle is coagulated with regeneration. Via post treatments of water rinsing, hydro-entangled needle punching, drying, winding-up and the like have been orderly applied, then final product of nonwoven fabrics with continuous filament are produced from natural cellulose.
