A stapled melt spinning method for producing nonwoven fabrics with hygroscopic metastatic feature. Firstly, fuse bio-polyamide 6,10 into melt, extrude and spin it out spin heads of extruder into filaments, cool, draw and collect filaments into tow, then extend, cut and card the filaments into the staples, and spread the staples on a conveyer to form fibrous web. Next, blend and dissolve pulp by N-methylmorpholine N-oxide (NMMO) dissolving solvent, dehydrate it to form dope, and extrude and spin it out spin heads of extruder into filaments, then cool, draw and collect filaments into tow, and extend, cut and card filaments into staples, then overlay the staples over existing fibrous web to form a composite fibrous web of bio-polyamide 6,10 and cellulose filaments. Finally, coagulate, regenerate and convert fibrous composite of bio-polyamide 6,10 and natural cellulose into nonwoven fabric with hygroscopic metastatic feature by hydro-entangled needle punching, drying, winding-up processes.
