Optimum travel temperature: 21 °C (70 °F)
Glow temperature: 205 °C (401 °F)
Fire point: 210 °C (410 °F)
Autoignition temperature: 360 °C (680 °F) - 425 °C (797 °F)
Autoignition temperature (for oily cotton): 120 °C (248 °F)
A temperature range of 25 to 35 °C (77 to 95 °F) is the optimal range for mold development. At temperatures below 0 °C (32 °F), rotting of wet cotton stops. Damaged cotton is sometimes stored at these temperatures to prevent further deterioration.
Egypt has a unique climatic temperature that the soil and the temperature provide an exceptional environment for cotton to grow rapidly.
