A polyurethaneurea fiber with the excellent stabilization of inorganic materials is provided to maintain the stability of viscosity of polyurethaneurea with high concentration of above 35%. The isocyanate first polymer is manufactured by the reaction mol ratio of 1:1.5 to 1.8 of glycol to diisocyanate. The mixture of ethylene diamine of 90 to 99.9 mol% and 1,2-diamiopropane of 0.1 to 10 mol% is polymerized with the first polymer by means of the chain extending agent so that the polyurethaneurea is manufactured. Thereafter, the polymer and the inorganic dispersion solution containing the low molecular weight polyurethane are mixed and spun so that the polyurethaneurea elastic yarn is manufactured. The polyurethane with low molecular weight is included into the polyurethane elastic yarn above 5 wt% and below 30 wt% relating to the polyurethaneurea polymer. The low molecular weight is about the molecular weight of 4,000 to 10,000.
