If I understand you right, you are asking how much heat it takes to light cloth that has been charred.
We used to place cloth in an airtight container such as an old metal coffee can and seal the top with aluminum foil and wire. We would then put the can in the fire and let the cloth char inside the can. Because there was no air in the can, the cloth would just char and not burn or be consumed by fire.
After it cooled, we would place the charred cloth in a waterproof container to be used for fire starting later. A spark dropped onto the charred cloth which was placed inside a small bundle of tinder would burn much like charcoal without the flames and that was used to ignite small tinder and wood shavings.
The Temperature? Good question. I don't know. Whatever the temperature is of a small spark.

What is the difference between ignition temperature and spontaneous ignition temperature in a fuel cell?
The minimum temperature the fuel ignites self sustained combustion is known as spontaneous ignition temperature. The temperature at which the substance is preheated and burns smoothly is known as ignition temperature.
What will happen if the ignition temperature is lower than the room temperature?
If the ignition temperature of a substance is lower than the room temperature where it is, then that substance ignites.

Why do doctors advice to put strips of wet cloth on the forehead of a person having high temperature.?
The evaporation of water from the cloth lowers the temperature of the cloth and thus hopefully by conduction the temperature of the person. Note that this method does not work in spaces with 100 % relative humidity.
What damage the ignition coil?
Temperature can cause damage to the ignition coil. Temperature which is above 150 degrees Celsius can cause a great damage to it.
