Summary:PROBLEM TO BE SOLVED: To provide an elastic fiber structure durable to a plurality of high temperature dying at ≥130°C and capable of raising heat set temperature even the fiber structure is composed of polyurethane elastic yarn. SOLUTION: The invention relates to the elastic fiber structure comprising a polyurethane urea elastic fiber the polymer of which comprises (a) 5-25 mol.%. of a structural unit having a specific side chain and (b) 95-75 mol.%. of a structural unit derived from tetrahydrofuran, and is obtained by polymerizing a polyalkylene ether diol having 250-10,000 of number average molecular weight, a diisocyanate compound and a symmetric aromatic diamino compound.
