摘　　要：通过对膨体弹力真丝的热学性能进行研究探讨 ,指出 ,由于受加工工艺的影响 ,膨体弹力真丝纤维内部的结构变得松弛 ,纤维的热分解点有所下降 ,纤维的热失重速度有所加快 ,同时指出 ,膨体弹力真丝在热分解过程中存在二次结晶化特征 ,但热分解后纤维残渣量明显减少 。The investigations made on the thermal properties of bulk stretch real silk show that the fibre tends to relaxation in its internal structure, drops in thermal decomposition points and accelerates in thermogravimetric loss under the influence imposed by the processing. Meanwhile, bulk stretch silk features secondary crystallization during thermal decomposition, but the fibre residue decreases remarkably after thermal decomposition, thus reflecting in some degree its inner structural transformation from crystallization morphology to α conformation.
