Spandex yarn is resistant to high temperatures.
The dry heat temperature of spandex is about 190 °C, and after exceeding 190 °C, the strength decreases significantly, so the setting temperature is generally controlled below this temperature; However, the temperature of spandex is about 130 °C, and after the temperature exceeds 120 °C, spandex begins to break, so its dyeing temperature should be controlled below this temperature.
