Abstract
The present invention provides a condensation type polyurethane fiber. The condensation type polyurethane fiber includes a condensation type polyurethane, the condensation type polyurethane includes a plurality of first segments having a plurality of terminal group having which is bonded to R2 of at least one of the first segments. R1 and R3 independently include a first organyl group of C2-C20. The first segments have the same or different R2. R2 includes a second organyl group of C2-C20. The amine value of the condensation type polyurethane is at least 10 meq/kg. The coefficient of variation of the condensation type polyurethane fibers is less than 6.
