Fabricating method for meltblown nonwoven from natural cellulose fiber blended with nano silver
The present invention provides a fabricating method for meltblown nonwoven from natural cellulose fiber blended with nano silver, which comprises following steps. Firstly, prepare nano silver colloidal sol by reduction titration for mixture of polyvinyl alcohol (PVA), silver nitrate (AgNO.sub.3) and sodium borohydride (NaBH.sub.4). Secondly, prepare mixing cellulose serum by blending agitation for mixture of wood pulp, N-methylmorpholine N-oxide (NMMO) and stabilizer. Thirdly, prepare blending mucilage from mixing cellulose serum via blending process. Fourthly, produce spinning dope by blending and dehydrating the nano silver colloidal sol and mixing cellulose serum. Fifthly, produce molten filament tow by meltblown spinning method in association with coagulation, regeneration in coagulation bath, and water rinse. Finally, by post treatments of hydro-entangled needle punching, drying, winding-up processes in proper order, obtain final product of meltblown nonwoven from natural cellulose fiber blended with nano silver, which is biodegradable with features of antibacterial and antistatic capabilities.
