Abstract
A spunbond method for producing non-woven fabric with deodorant feature from bamboo cellulose comprises following process steps. Prepare bamboo pulp mixture by blending bamboo pulp and coffee residue in proper mixing ratio. Put N-methylmorpholine N-oxide (NMMO) as solvent and 1, 3-phenylene-bis 2-oxazoline (BOX) as stabilizer into prepared bamboo pulp mixture to form dope. Via spunbond method, orderly perform extruding, spinning, quenching and pre-drawing process to convert the dope into bamboo filaments of fibrous strand. Orderly process coagulation, regeneration and post-draw to the bamboo filaments of fibrous strand to transform them into uniform fine bamboo cellulose filaments. Bond and lay these bamboo filaments of fibrous strand on a belt collector to form a webbed nonwoven. After post treatments of water rinsing, hydro-entangled needle punching and drying have been orderly applied, then a resultant nonwoven fabric in continuous filament of bamboo cellulose with deodorant feature is produced from the webbed nonwoven.
