通过强力测试、弹性测试、热重分析、差示扫描量热法等手段对纯氨纶丝、棉弹力布和T/C弹力布的断裂强力、回弹性、耐热性进行了分析。研究发现，纯氨纶丝和棉弹力布在150℃以下焙烘强力损失不明显；当温度上升到150℃以上时，强力开始明显下降；170℃时，弹性开始严重损失。说明要使纯氨纶丝或棉弹力布在加工后仍保持良好的弹性，纯氨纶丝和棉弹力布的加工温度不宜超过170℃。T/C弹力布有相似的规律，只是其弹性骤降对应的温度也为170℃，强力骤降对应的温度提高到了180℃。故为保持T/C弹力布的良好回弹性能，实际加工中焙烘温度不宜超过180℃。

The breaking strength, elasticity, heat resistance of polyurethane filament, cotton elastic fabric and T/C elastic fabric were analyzed by strength test, flexible test, thermal gravimetric analysis and differential scanning calorimetry. The results showed that the strength losses of polyurethane filament and cotton elastic fabric were not obvious with the baking temperature below 150℃. But the strength decreased significantly as the temperature increased above 150℃. The flexibility began to decrease seriously at 170℃. The processing temperature should not be higher than 170℃so that the polyurethane filament and cotton elastic fabric can still maintain good elasticity after being processed. For the T/C elastic fabric, the temperature of sharp decrease in flexibility was also 170℃, while the temperature of sharp decrease in strength increased to 180℃. And the processing temperature of the T/C elastic fabric should not be above 180℃.
