摘要 |
Disclosed is an elastic polyurethane yarn which can exhibit excellent heat resistance even when an unsaturated fatty acid or a heavy metal is attached to the yarn during dyeing at a high temperature, and which has high elastic recovery and high strenth/elongation. Specifically disclosed is an elastic yarn comprising a polyurethane mainly composed of a polymer diol and a diisocyanate, which contains (a) a hindered phenol compound, (b) an N,N-dialkylsemicarbazide compound and (c) a nitrogenated aromatic compound, wherein the nitrogenated aromatic compound (c) is contained in an amount of 0.01 to 0.30 weight % inclusive. |
