Beschreibung
Zusammenfassung:	A polyurethaneurea elastic fiber, a method for producing the same, and a composition for the same are provided to improve the chlorine-resistant property and the spinnability of the polyurethaneurea elastic fiber, by using basic magnesium carbonate as a chlorine-resistant additive. A composition for a polyurethaneurea elastic fiber contains 0.1-1.0 wt% of basic magnesium carbonate as a chlorine-resistant agent. The basic magnesium carbonate is coated with a coating agent in a wet type or a dry type, or capsuled in the coating agent. The 0.1-1.0 wt% of coating agent is used based on the basic magnesium carbonate. The coating agent is one or more selected from fatty acid of C1-C30, fatty-acid metal salt, fatty-acid ester, fatty-acid phosphoric ester, silica, silane, polyorganosiloxane, and a mixture of polyorganosiloxane and polyorganohydroxygensiloxane.
