| titleOfInvention | Method for preparing polyurethaneurea elastic fiber |
| abstract | The present invention relates to a process for producing a polyurethane precursor, which comprises polymerizing a polyol and a diisocyanate to prepare a polyurethane precursor and then dissolving the polyurethane precursor in a solvent to prepare a prepolymer solution; Dissolving the chain extender and the chain extender in a solvent to prepare an amine solution; Stirring and chain extending the prepolymer solution and the amine solution to prepare a polyurethane urea spinning solution having an intrinsic viscosity of 1.0 or more; Stirring the solution at 40 to 70 DEG C until the viscosity of the spinning solution becomes 4,000 to 10,000 Poise, and then storing the solution; And spinning and winding the polyurethane-urea spinning stock solution, wherein the chain extender comprises ethylenediamine and diethylenetriamine, wherein the polyurethane-urea elastic yarn comprises Method can provide a polyurethane-urea elastic yarn having excellent modulus and heat resistance by producing a polyurethane-urea elastic yarn as a spinning stock solution having excellent storage stability. |
