PROBLEM TO BE SOLVED: To provide a polyurethane elastic yarn satisfying an acceptable quality level set based on an evaluation method for an elastic warp knit fabric using a polyurethane elastic yarn, prepared by assuming the use of a consumer such as repeating wearing, washing, drying in the sun and chlorine bleaching. SOLUTION: The level acceptable by the consumer is set by providing the method for testing complex embrittlement by assuming the wearing, the washing, the drying in the sun, and the chlorine bleaching. (a) A phenol-based antioxidant, (b) a phosphite-based antioxidant and (c) a hindered amine compound having a specific structure are compounded with the polyurethane elastic yarn used in an elastic woven or knitted fabric to satisfy the level.
