A flame requires an adequate supply of oxygen to sustain combustion. The exact amount of oxygen needed varies depending on the fuel and the conditions of the combustion process. Generally, a balanced ratio of oxygen and fuel is necessary for efficient burning.
The minimum concentration of oxygen required for combustion is typically around 16% in air. Below this level, the fuel will not be able to sustain a flame or combust.
When the correct amount of Oxygen is mixed with the Acetylene a NEUTRAL flame is produced. Less than that amount produces a CARBURIZING flame. Too much Oxygen creates an OXIDIZING flame. Most welding/cutting is done with a NEUTRAL flame but all flame adjustments have their purpose.
Sulfur burns with a blue flame when it reacts with oxygen.
Copper burns with a green flame when ignited with oxygen.
The flame color of barium burning in oxygen is green.
OXYGEN
Oxygen is required in order for a fire to continue burning. Without oxygen a flame will extinquish itself.

flame needs oxygen in order to keep on burning. fabric might cut that source of oxygen and the fire might go out, but there is a limit to how much flame a fabric can put out I think...

Little/none
air will burst into flame in pure oxygen
The flame of a candle requires oxygen to continue burning. When you cut off the air supply, the flame is deprived of oxygen which is essential for the combustion process. Without oxygen, the flame cannot sustain itself and eventually dies out.

Mixing Acetylene and Oxygen in the correct proportions produces an extremely hot flame. Using just enough Oxygen so that the Acetylene is almost completely consumed in the flame is called a Neutral Flame. In most welding and cutting applications you would utilize this flame. Reducing the amount of Oxygen produces a Carburizing Flame. It is yellowish and not as hot as a Neutral Flame, but, is used in certain situations. Welding Aluminum is one. Increasing the Oxygen produces an Oxidizing Flame. It produces a flame that is pointed, colder, and louder than a Neutral Flame. It wastes fuel and isn't as efficient as a Neutral Flame.
