Spunbond wetlaid method for producing non-woven fabrics from natural cellulose |
| abstract |
The present invention provides a “spunbond 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. Then, the dope is extruded out of a spinneret to form filament bundle by spunbond method. The dope is extruded out of a spinneret bank of grouped spinnerets to form filament bundle for further stretching process under quench condition. The filament bundle is coagulated with regeneration in a coagulating solution. The coagulated filament bundle is rapidly stretched under high pressure by an air draw-off machine. The stretched filament bundle is collected and stacked on a collecting net as web nonwoven. After 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. |
