Polyurethaneurea elastic fiber and method for preparation thereof |
| abstract |
The present invention relates to a preparation method of a polyurethaneurea elastic fiber, in which the sub-reaction and reaction speed are regulated during the prepolymer reaction by adding 1- functional monoalcohol and an organic acid in order to provide an elastic fiber exhibiting excellent uniformity during the weaving and processing of a synthetic fiber such as polyester or nylon, a static mixer having excellent stirring efficiency and a tubular reactor are used for constant even reaction to give a primary uniform polymer, the primary polymer is dissolved in a solvent using a high shear mixer, and a chain extender and chain terminator are added with regulation to give the secondary polymer having intrinsic viscosity of at least 1.0. In the present invention, a high shear mixer for the secondary polymerization exhibiting at least 80% of stirring efficiency and a cylindrical pipe shaped static mixer were used to inhibit sub-reaction and gelation to give a secondary polymer exhibiting stable spinning. |
