Abstract

The present invention relates to a kind of polyurethane elastomeric fibers and preparation method thereof, firstly, carrying out prepolymerization after end hydroxy polyether is mixed with diisocyanate obtains performed polymer；Secondly, performed polymer is dissolved to obtain prepolymer solution；Chain extender is added in batches again and terminator carries out chain extending reaction and obtains polyurethane solutions, chain extender is anti-form-1,4- diaminocyclohexane and/or cis- -1,4- diaminocyclohexane, the ratio of anti-form-1, the total additional amount of 4- diaminocyclohexane and cis--total additional amount of Isosorbide-5-Nitrae-diaminocyclohexane is 1, cis--Isosorbide-5-Nitrae-diaminocyclohexane content is 25~100wt% in the chain extender that first batch is added；Final spinning obtains in polyurethane elastomeric fiber on molecular backbone while containing there are three types of hard segment structures.Present invention process is simple, safety and environmental protection, is convenient for large-scale production, and products obtained therefrom also has excellent heat resistance while ensure that excellent elastic performance.
