PROBLEM TO BE SOLVED: To provide elastic fabric having excellent high heat resistance in dying (high heat resistance when an unsaturated fatty acid or a heavy metal adheres thereto, in particular). SOLUTION: The elastic fabric includes polyurethane elastic fiber which is formed by copolymerizing polytrimethylene ether glycol having crystallization energy of 10J/g or more and crystallization temperature of -60 to -40°C diisocyanate and diamine chain extender, which has DSC melting point falling in a range of 120-150°C, and in which enthalpy in a range of 120-150°C is 5.5J/g or more.
